How to debug the thread rolling machine

The cold rolling process of thread rolling is an advanced non-cutting process, which can effectively improve the internal and surface quality of the workpiece. The radial compressive stress generated during processing can significantly improve the fatigue strength of the workpiece. and torsional strength, it is an ideal process with high efficiency, energy saving, and low consumption.

Let’s take a look at how to use the steel straight-thread rolling machine.

1. Adjustment of the machine.

To change the position of the automatic manual switch of the electrical control box, you can choose automatic or pedal rolling. Automatic circulation rolling: Turn the rolling button of the electrical control box to the automatic position, and the movable thread rolling shaft will reciprocate under the control of the time relay.

Manual rolling: Turn the rolling switch of the electrical control box to the manual position, and then press the manual rolling switch, the movable thread rolling wheel can be used for work.

Foot rolling: Turn the rolling switch to the manual position, and the movable thread rolling wheel can work under the control of the foot switch.

2. Installation of the thread rolling wheel.

Unscrew the hexagon socket head cap screw of the thread rolling shaft head cover of the threading machine, remove the front bearing seat of the thread rolling shaft to install the thread rolling wheel, and adjust the axial position of the thread rolling wheel with the spacer or fine adjustment.

3.  Adjustment of T-shaped bracket and support block.

The position of the T-shaped bracket is adjusted according to the diameter of the rolling wheel and the diameter of the rolling material. Loosen the two fixing screws on the T-shaped bracket and move the T-shaped bracket to the appropriate position. The support block used on the bracket is welded with cemented carbide, which is ground and ground. The surface of the cemented carbide is required to be smooth and straight. The choice of the width of the support block is related to the diameter of the workpiece to be processed.

Adjustment of the T-shaped bracket: The T-shaped bracket is used to support the workpiece and keep it in a correct position between the two rolling wheels for rolling. (If special specifications of T-shaped brackets or support blocks are required, users should prepare them.) The T-shaped bracket of this machine is fixed at the center position below the second rolling shaft. As the diameter of the workpiece changes, so does the position of the bracket.

At this time, the center distance of the two thread rolling wheels is the initial center distance of the rolled workpiece, and the final value should be further adjusted according to the center diameter of the workpiece during the test rolling.

Adjustment method of indentation method:

(1) The time method is the same as the above, but the workpiece blank without thread is placed in the opposite tooth position.

(2) Shake the center distance adjustment handle of the main shaft, so that the two thread rolling wheels are clamped to the workpiece blank, and the clamping degree is such that the visible indentation can be pressed out.

(3) Shake the pulley to drive the main shaft, and drive the two thread rolling wheels to press the workpiece to make the workpiece rotate half a circle.

(4) Reverse the “spindle center distance adjustment handle”, remove the workpiece blank, and observe whether the indentation tooth position is adjusted properly. If the tooth position is not adjusted, it needs to be adjusted.

(5) When adjusting by the indentation method, the center distance of the two main shafts is greater than the center distance of the normal rolling working time, so it is necessary to shake the “main shaft center distance adjustment handle” at the adjusted position to shorten the distance between the two rolling wheels by two The distance of the tooth height (that is, 2 2/3 pitches). The correct center distance should be adjusted and determined according to the working pitch diameter during the test rolling process. Hydraulic stroke consists of two parts: working stroke and idle stroke.

The working stroke corresponds to the tooth profile height of the thread. The idle stroke is the stroke required by the process and operation. Under the allowable conditions, the smaller the idle stroke, the higher the production volume.

RIDE ON POWER TROWEL

1. Product introduction 

A trowel is a tool for rough and fine troweling of the concrete surface. The machine-constructed surface is smoother and flatter than the manual construction surface, which can greatly improve the compactness and wear resistance of the concrete surface, and improve the work efficiency by more than 10 times compared with manual operation.  

 2. Product use 

Mainly used for grouting, compaction, smoothing and troweling of concrete surfaces. The ground troweling machine can be widely used for grouting, troweling, and troweling of concrete surfaces of high-standard workshops, warehouses, parking lots, squares, airports and frame buildings. It is the tool of choice in concrete construction.

3. Operating Rules

1). Before driving the trowel, check whether the cables, switches, and other equipment are normal, and check whether the polishing pads, nuts, etc. are loose. Wear protective gear when operating.

2). When the trowel is to be parked on a slope, it should be turned off and placed on the slope, and wedges should be placed under the front and rear wheels. It should be ensured that the location where the trowel is parked will not cause traffic accidents.

3). The dragging of the trowel generally does not exceed 200m.

4). When towing the trowel, the hydrostatic device should be in a disengaged state, that is, the small button located under the hydrostatic device should be pressed into the pump body, and the towing speed should not be higher than 3km/h.

5). Whether it is rolling uphill or rolling downhill, the driving wheel of the trowel should be behind. Because when going uphill, the rear driving wheel can bear the driving force provided by the ramp and the machine itself, and at the same time, the front wheel performs preliminary compaction on the road surface to withstand the large shear force generated by the driving wheel; when going downhill, wipe The impact force generated by the self-weight of the light machine is offset by the braking of the driving wheel. Only the mixture rolled by the front wheel has the ability to support the rear driving wheel to generate shearing force.

6). After the work of the trowel is completed, turn off the switch in time and disconnect from the power supply. When placing the trowel, the blade of the trowel should be downward, so as not to hurt people due to the inertial rotation of the blade.

Analysis and countermeasures for common problems when bending pipes by pipe bending machines

1. The cross-section of the curved section is severely flattened:

Possible reasons: the mold cavity is not round; the position of the mandrel is behind, or the mandrel balls are few, which cannot effectively support the bending section, resulting in collapse; at the tangent point of the bending, the pressure of the die is not enough; when bending, the pipe is in the clamping die Slight sliding, at this point just check the gripping section for scratches.

Solution: Check the mold cavity, and replace the mold if it is not correct; move the position of the mandrel forward, if the tangent point of the curved arc cannot be reached, increase the number of balls; increase the die pressure and boost pressure; if there are slip marks in the clamping section, the clamping pressure should be increased.

2. Excessive collapse of the bending section:

Possible reasons: The mandrel is not supported enough; the rotation speed is greater than the boost speed, and the tube is clamped too tightly.

Solution: Move the mandrel position forward, if it is not enough, increase the number of balls. Or turn the plug into a ball, adjust the rotation speed or boost speed, and reduce the die pressure.

3. Tool indentation:

(1) Section indentation in the clamping die area

   ①Semi-circular indentation at the joints of the inserts

   Possible reasons: the inserts on the wheel die are not well matched, and there are steps.

   Solution: use the integral mold or modify the mating surface of the insert.

   ②Indentation at both ends or one end of the clamp

   Possible reasons: For deep indentation at both ends, the clamping pressure may be too high. If there is an indentation in the axial direction at the same time, it means that the diameter of the pipe is large; for indentation at one end, the clamping die may be inclined in the axial direction. Spend.

Solution: For deep indentation at both ends, reduce the clamping pressure and strictly control the size of the pipe; for indentation at one end, copper skin can be added behind the clamp to adjust the slope; when the straight section of the pipe is smaller than the length of the clamp, in order to increase the clamp Die clamping force, the auxiliary mandrel can be added.

   (2) Axial indentation in the clamping die/die area

    Possible reasons: The clamping force is too large, the size of the matching mold cavity is too large or too small; the center of the matching mold groove is misaligned; this phenomenon also occurs when the pipe diameter is large.

Solution: Use a mold with the correct cavity size; align the center of the mold groove, while reducing the clamping force appropriately; strictly control the diameter of the pipe.

   (3) Axial indentation of bending section

Possible reasons: The center of the die and the wheel die are not vertically aligned or the die cavity is small; this phenomenon also occurs when the pipe diameter is large.

Solution: adjust the vertical alignment of the center of the die, increase the gap between the die and the wheel die, and reduce the die pressure; if there is still an indentation, measure whether the pipe diameter matches.

4. Bend the medial folds:

(1) The entire curved arc is covered with wrinkles and extends to the anti-wrinkle mold area

    Possible reasons: The anti-wrinkle die is located at the back and the size of the groove is large, which cannot effectively support the tube wall; the gap between the die and the anti-wrinkle die/wheel die is large, and the pressure of the die is small; the diameter and position of the mandrel are incorrect.

Solution: Check the diameter of the mandrel and the mold groove, and select the correct mold; narrow the gap between the compression mold and the anti-wrinkle mold or the wheel mold, increase the pressure, and push the anti-wrinkle mold forward; the mandrel gradually (1.5mm) advances forward, until a satisfactory result is obtained.

   (2) There are wrinkles between 45º~90º of the curved arc, and most of them are at the bottom

Possible reasons: The cavity of the wheel model is not round, and the alignment of the positioning ring and the positioning block is not concentric; the gap between the die and the anti-wrinkle die or the wheel die is large, and the pressure of the die is small.

Solution: reduce the gap, increase the pressure, and push the anti-wrinkle mold forward. If necessary, sink the die cavity as a whole, and place a copper sheet after the die.

   (3) Wrinkles appear in the straight line segment after bending the arc

Possible reasons: the inclination of the anti-wrinkle die is too large, and the tube wall cannot be effectively supported; the gap between the anti-wrinkle die and the die is large; the diameter of the straight section of the mandrel is small, and the gap is too large after inserting the tube, and the tube wall cannot be effectively supported; The boost force is large or the boost speed does not match the rotation speed; check the wall thickness of the pipe in the bending section, if the thickness is not reduced much, it means that the pressure of the die may be small; the tip of the anti-wrinkle die is worn, and the root does not fit well with the wheel mold cavity.

Solution: reduce the inclination of the anti-wrinkle mold, reduce the inclination of the anti-wrinkle mold, and reduce the gap between the anti-wrinkle molds; detect the wall thickness of the pipe in the bending section, and increase the pressure of the mold when the thickness is satisfied; detect the core If the diameter of the shaft is small, replace the mandrel; adjust the boost pressure, and adjust the boost speed to match the rotation speed; repair the anti-wrinkle mold, so that the contact surface between the rear root and the wheel mold cavity should be at least 80%, and the distance between the front and the wheel mold should be at least 80%. The cutting point of the wheel die is 2~3mm, and the thickness of the tip should be uniform up and down.

5. Scratches:

(1) Scratches appear in the curved arc and the anti-wrinkle die area

Possible reasons: There are burrs on the surface of the pipe; there are metal slag, chips, or irregular fluff on the surface of the die or the anti-wrinkle mold cavity; the size of the mandrel is small; The material of the tubing does not match.

Solution: increase the inclination of the anti-wrinkle die, the pressure of the die, or the surface roughness; clean or polish the surface of the pipe and the mold cavity; add diesel oil or lubricating oil to the anti-wrinkle die area; adjust the boost pressure or speed to match the rotation speed; Anti-wrinkle mold material compatible with the material of the pipe to be bent;

  (2) There are wrinkles in the arc segment, and straight line scratches appear in the clamping area

Possible reasons: The clamping force of the die and the clamping force of the die do not match; the position of the mandrel and the anti-wrinkle die may be wrong; the roughness of the die cavity is low; there are metal slag, chips, burrs on the surface of the pipe or the surface of the die cavity Or oil stains; excessive clamping force makes the clamping die against the ball of the mandrel, clamping the pipe and causing friction marks.

Solution: adjust the clamping force of the die and the clamping die; check the position of the mandrel and the anti-wrinkle die and the lubricating oil condition; spray carbide spray to the clamping die cavity, or increase the roughness; clean or polish the surface of the pipe or Clamp the mold cavity, no particles, burrs or oil stains are allowed.

6. The wall thickness is smaller than the standard requirement:

Possible reasons: the boosting speed is lower than the rotation speed; the pressure of the die is large and the boosting force is small; the wall thickness of the raw material of the pipe is small.

Solution: increase the boost force and boost speed; reduce the pressure of the die or increase the gap between the die and the wheel die/anti-wrinkle die; detect the circumferential wall thickness of the pipe, and select the relatively thick side to put it out; down, minimize the length of the end of the pipe to facilitate metal flow.

7. A straight line segment appears before the tangent point of the bent end:

Possible reasons: The mandrel fails to effectively support the pipe, and the mandrel pitch is large.

Solution: Re-process the coupling joint of the ball to reduce the pitch.

8. Bend rebound:

Possible reasons: When the pipe is bent and loaded, the pipe wall material is elastically and plastically deformed. After unloading, the deformation due to the elasticity of the material must be restored, that is, bending rebound occurs.

Solution: mainly use compensation method and correction method to control.

The compensation method is to comprehensively analyze the influencing factors of bending spring back, pre-estimate the amount of spring back according to various conditions and spring back trends during bending, and modify the size and geometry of the working part of the convex and concave die when designing and manufacturing the mold. “Over-positive” bends.

The correction method is to take measures on the mold structure, so that the correction force is concentrated at the bend, changing the force state, trying to eliminate the elastic deformation and overcome the spring back. For example, in the stretch-bending process, tension is applied while bending, so that the entire section is under the action of tensile stress. When unloading, the elastic recovery is consistent with the deformation direction, which can significantly reduce the amount of rebound.

Classification and scope of application of pipe bending machines:

1. Classification of pipe bending machines:

According to whether the pipe is heated or not, it is divided into a cold pipe bending machine and a hot push pipe bending machine

The transmission mode is divided into 4 types: pneumatic, manual, mechanical transmission, and hydraulic transmission

Divided into 4 types according to the control mode: manual control, semi-automatic, automatic, and numerical control

2. Scope of application of pipe bending machine:

Pipe bending machines are generally classified according to the control method, and they are introduced one by one as follows:

Manually controlled pipe bending machine: Manually controlled pipe bending machine: Manual pipe bending is the use of simple pipe bending devices to bend pipes. It does not require special pipe bending equipment, the pipe bending device has low manufacturing cost, convenient adjustment, and use, but high labor intensity and low productivity, and is mainly used in single-piece and small batch production.

Semi-automatic control pipe bending machine: generally only automatically control the bending angle, mainly used for medium and small batch production.

Automatic control of pipe bending machine: The whole process of pipe bending (feeding, pipe bending, and space angle) is automatically controlled through the size pre-selection mechanism, feeding trolley, and program control system. This kind of pipe dazzling machine generally adopts hydraulic transmission and servo motor control. The production efficiency is high, but the initial investment is large, and it is not suitable for occasions where the pipe size parameters are changeable, and it is suitable for mass production.

CNC pipe bending machine: It can realize the automatic control of the pipe bending process by inputting data according to the size specified in the part drawing. It is suitable for mass production, especially when the pipe size parameters are changeable.

Countermeasures for analysis of common problems when using pipe bending machines to bend pipes:

From the process analysis, it can be seen that the common elbow defects are wrinkles, bulging, tool indentation, fracture, insufficient wall thickness, and bending spring back. The existence of elbow defects will have a great negative impact on the quality of the bent pipe. . Therefore, corresponding measures should be taken to prevent the above-mentioned defects before bending, so as to obtain the ideal pipe and ensure the various performance indicators and appearance quality of the product. The following is an analysis of common elbow defects in production, and corresponding solutions are proposed:

Metal accumulation:

Possible reasons: The tip of the anti-wrinkle die is thick and positioned at the front, and a step is formed after the cut point of the wheel die. When bending, the metal inside the tube is compressed. When the hardness of the tube material is low, accumulation is formed here.

 Solution: repair the root of the anti-wrinkle die and reduce the thickness of the tip of the anti-wrinkle die; grind the tip of the anti-wrinkle die to make it smoothly transition to the surface of the wheel die; in the case of no wrinkle, the anti-wrinkle die is withdrawn until the accumulation disappear.

Metal split layer:

Possible reasons: The tip of the anti-wrinkle die is thick and positioned in the front, forming a step after the cutting point of the wheel die, and the metal inside the tube is compressed during bending, and the layers are staggered here.

 Solution: Refer to the solution for metal buildup.

Bend pits:

 Possible reasons: The size of the mandrel is small or the boosting speed is too much greater than the rotation speed during mold adjustment, and the die pressure and boosting pressure are large.

 Solution: Select the correct mandrel size and reduce the boost speed, die pressure, and boost pressure.

Cracks appear on the outside of the bent tail:

Possible reasons: The surface of the mandrel is rough or there are metal shavings between the core ball and the shaft; the surface of the die cavity is irregular, with undulations or metal shavings; the die is too tight against the pipe, causing excessive frictional resistance, resulting in rupture.

Solution: Check the surface of the mandrel or the mold cavity for defects, and repair the mold if necessary; reduce the boost and mold pressure, increase the gap between the mold and the anti-wrinkle mold; eliminate metal chips and metal slag on the mold surface.

Bending fracture:

Possible reasons: There are obvious transverse pits on the surface of the pipe, and the die is too tight against the pipe, causing excessive frictional resistance and rupture; the size of the mandrel is large, and the pipe is too tight after being inserted; the position of the mandrel exceeds the cutting point of the wheel die too much; The pressure of the die is large, the booster and clamping pressure are not enough, causing slipping and breaking; the surface of the die, the clamping die or the pipe is oily, causing the surface to slip and break; the surface of the die is smooth, causing the pipe to slip and break; the boosting speed is less than the rotation speed, The tube wall is thinned and broken; the mandrel is not properly lubricated or the surface is rough, resulting in large resistance and rupture.

 Solution: Strictly control the surface quality of the pipe; adjust the boosting speed or rotation speed; check whether the size or position of the mandrel is appropriate; check whether there is oil on the surface of the clamping die and the die, and clean the surface; check the die, anti-wrinkle die, wheel die to Check whether the gap is suitable, adjust it properly; check whether the pressure of the die and the clamping die is suitable, and adjust it appropriately; if the clamping dies still cannot be clamped after adjusting the pressure and gap, an auxiliary mandrel can be added, or the surface of the clamping die cavity can be roughened; Lubricate the mandrel or polish with emery while checking that the mandrel material and lubricant are compatible with the pipe material.

Curved end section convex hull:

Possible reasons: The mandrel exceeds the cutting point of the die too much during adjustment.

Solution: withdraw the mandrel until the bulge disappears. If there are wrinkles, the number of heart balls can be increased.

The axial double convex hull of the curved segment:

Possible reasons: The size of the mold cavity is too small or the diameter of the pipe is large, and the metal is extruded into an ear shape under high pressure.

 Solution: Use a bending die with the correct cavity size; reduce the die pressure/assist pressure, increase the clearance between the die and the anti-wrinkle die/wheel die, or reduce the boost stroke; properly lubricate the edges and corners of the die cavity, strictly Control tube size.

Bending segment mandrel spherical mound convex:

Possible reasons: The compression molding is too tight, and the boost force is less than the bending tension; the mandrel ball pitch is large.

 Solution: reduce the die pressure, increase the boost force; reduce the mandrel ball pitch.

How should the maintenance of the concrete pump be carried out?

A concrete pump is a kind of construction equipment commonly used by construction parties. It can greatly improve the efficiency of construction and is deeply welcomed by construction parties. However, in order to prolong the service life of the concrete pump, it is very important to maintain certain concrete pump maintenance skills.

So how should the maintenance of the concrete pump be carried out?

Specifically, we can start from the following aspects.

1. Hydraulic oil

Hydraulic oil is a working medium that requires a high degree of cleanliness. The upper cover of the hydraulic oil tank cannot be opened casually, so as to prevent impurities from mixing into the hydraulic oil. It should be reminded that the hydraulic oil should be replaced after 300 hours of work for the first time, and the hydraulic oil should be replaced every 600 hours after the work.

2. Thermometer

Under normal circumstances, the thermometer usually displays the oil temperature of the hydraulic oil, and the normal working temperature of the hydraulic oil is generally 30℃-60℃, and the highest oil temperature generally does not exceed 70℃.

3. Oil level gauge

The oil level gauge can generally be used to observe the amount of oil in the oil tank. Usually, the oil level of the oil level gauge must be located above the specified scale during operation. If it is missing, add hydraulic oil immediately.

4. Drain valve

The use of drain valve can generally be used to open the tank when cleaning, usually, the drain valve is closed. The drain valve can be opened once a week after 24 hours of the shutdown to remove the water deposited at the bottom of the fuel tank.

5. Air filter (on the hydraulic oil tank)

The air filter can prevent foreign debris from mixing in and filtering the air, and it is recommended to replace it every six months.

6. High-pressure oil filter (one for the main system and one for boom system)

When the prismatic pointer on the oil filter points to the green mark, it means that the work is normal and the filter element is not blocked; when the pointer points to the yellow color mark, it means that the filter element is blocked, but it can continue to work; when the pointer points to the red mark, indicating that the filter element is seriously blocked and cannot continue to work, and the filter element must be replaced immediately, and the filter element should be replaced at the same time every time the hydraulic oil is replaced.

7. Fastening elements

Before starting the machine every day, check whether the fasteners are loose. If they are loose, they should be tightened before proceeding to the next step.

8. Cylinder seals

Cylinder seals should be replaced every 1000 hours of operation.

9. Electrical components

Before starting the machine every day, check whether the electrical components and connections are abnormally loose.9. Electrical components

10. Swing valve cylinder ball head and upper and lower spherical bearings

The ball head of the swing valve cylinder and the upper and lower spherical bearings should be checked once every 500 hours of operation, and if the wear is serious, it should be replaced in time.

A concrete pump is a kind of construction equipment commonly used by many construction parties at present. Good maintenance of concrete pumps in daily life can prolong their service life. Through the above introduction, I believe that the majority of users have already understood the maintenance skills of concrete pumps.

Do you know what are the main configurations of concrete pumps?

What is the concrete pump?

A concrete pump consists of a pump body and delivery pipe. It is a machine that uses pressure to continuously transport concrete along the pipeline. It is mainly used in housing construction, bridge, and tunnel construction.

A concrete pump has the following main technical parameters: delivery capacity, outlet pressure, motor power, and distribution valve form.

Do you know the main configuration of the concrete pumps?

Main engine power: Electric Motors or Diesel Engines

The motor power of a concrete pump is a prerequisite for determining the outlet pressure and delivery volume. With a certain motor power, the increase in pressure will inevitably reduce the delivery volume; on the contrary, reducing the outlet pressure will cause the delivery volume. increase.

In order to ensure that the concrete delivery pump must have a large delivery volume, but also have a certain outlet pressure and matching economic power, in the design of the concrete delivery pump, most of the constant power plunger pumps are used; that is, the constant power value After selection, when the outlet pressure rises, the output displacement of the oil pump will automatically decrease to reach the value corresponding to the power design; if you want to achieve high outlet pressure and large delivery volume The only way is to increase the motor power.
