③ maintenance and maintenance

  1. After CNC reinforcement straightening cutting machine is used continuously for half a year, it is recommended to conduct major maintenance, remove and wash the transmission parts, replace with clean lubricating oil, and carefully check the smooth condition of the oil road, which should be repaired in time when problems are found in the demolition and cleaning.
  2. Finds straightening tube deformation when in use and must stop use and regrinding.
  3. After the grinding times of the straightening roller, the diameter of the straightening roller is less than the requirements, the top of the transmission gear is tight and the gap between the rollers remains. At this time, the gear must be corrected.
  4. The front edge of the feed blade should be carefully corrected before installation, refined and smooth, allowing absolutely no sprinklers and cracks.
  5. After the blade is short, screw the sinking head screw and move out for use.

Cause and troubleshooting method:

The knife table is topped out for navigationExcessive movement resistance in the material tankAdjust the spin amount of the support column, adjust the offset, improve the straightening quality, and increase the pull rod spring to press the external force
Use a mirror with a knifeThe rod spring has the less tight force The increased tightening force method is the same as 1
Undetermined dimensions fall from the material tankThe support column is shortAdjust support column
Reinforcement is not straightThe alignment block offset is smallIncrease offset
Reinforced surface pull injuryThe roller pressure is too large, and the straightening block is damagedReduce the pressure and replace the adjustment block
Bend silk Adjust the straightening block angle, look at the regulator and roll slot, and cut off the total it all on a straight line
Short knots appear Slide with host pull spring over loose, adjust the pull spring
The machine vibrates too much Adjust the balance of the straightening block

What do we need to prepare before and after construction when we use a mortar spraying machine?

Before starting the construction, make sure that the wall of the construction wall has enough water absorption after repeated spraying to wet the wall so that there is enough wall treatment time after the wall is sprayed, and the cement shear wall that needs to be roughened should be roughened in advance.

Before each start-up construction, about 30 liters of 4:6 pure cement mixed water must be added to the hopper and sprayed out, and mortar should be added after the pipeline is fully lubricated. When spraying, the operator should wear protective glasses and wear protection Wear a jacket.

The downtime during construction should be determined by the solidification and denaturation time of the mortar material. If the solidification time of the material is short and the speed is fast, the downtime should be shortened. If the time is exceeded, it should be sprayed in time and handled in accordance with the end of construction.

At the end of each construction, the remaining mortar materials in the hopper must be completely sprayed out or cleaned up (the main machine must be turned off when manually cleaning the materials in the hopper to prevent mechanical injury). Then add 30-50 liters of 4:6 pure cement mixing water that is evenly mixed in advance to completely eject the remaining mortar material in the conveying pipe, and then repeatedly clean the inside of the pipe with clean water and spray to ensure that the conveying pipe is clean and free of residue.

Help you pave a smooth road— concrete vibratory screed

Concrete slabs can be seen everywhere-from your parking lot to the paved road, from your kitchen to your bedroom.

Have you ever wondered why they are so flat and smooth?

Can it be done only by manual labor? Maybe, yes, but to achieve such a precise, almost perfect horizontal surface, the answer is no. So how can we have such a level ground?

There is a magical machine called a vibrating ruler, which can perfectly smooth the surface and make the surface a single level with appropriate slope and smoothness.

A vibrating concrete screed is a piece of equipment made to screeding the concrete to make it smooth and level.

It is a machine-powered tool that allows labor to smoothen and level out fresh concrete from a standing position.

A motor produces attached to it produces the vibrating action. Hence there is a reduction of effort required by the worker. He or she will only need to pull the screed across the entire surface. Rest is left with the machine it will smoothen it out.

Vibrating screed is a commonly used tool in construction machinery, mainly used to remove the air in the concrete during construction and increase the viscosity of the concrete. The vibrating ruler has a wide range of uses. The vibrating screen is also called the hand-held vibrating ruler. According to the power, it can be divided into a gasoline vibrating screed and an electric vibrating flat ruler.

Features of the hand-held vibrating ruler

1. Lightweight body, easy to use, safe, handle height can be adjusted, suitable for people of different heights

2. The aluminum alloy blade is durable and has high flatness

3. The blade length is suitable for 1-3 meters, * easy to change

4. Fast speed and easy to carry. Scrape, complete in one time, construction is convenient and quick

5. The operator can adjust the excitation force at any time, and the vibration frequency can be controlled by the manual throttle

 It overcomes the hollow, bulging, and cracking phenomenon that has been trapped on the concrete floor for a long time after construction, and realizes a solid, solid concrete floor.

What is a threading machine?

What is a threading machine?

Threading machine is also known as electric threading machine, electric pipe threading machine, threading machine, pipe threading machine, steel bar threading machine. Threading machine is a motorized manual pipe thread twisting plate before 1980. It makes pipe thread processing during pipe installation easier and faster and reduces the labor intensity of pipe installation workers.

What is a rebar thread rolling machine?

The steel bar thread rolling machine is a machine that uses the advanced technology of stripping and rolling to process the straight threads of the connection ends of the steel bars. The steel straight threaded metal fiber processed by it is continuously dense and has good comprehensive mechanical properties. The tensile strength is increased by 20%-30%, the fatigue strength is increased by 40%-60%, and the corrosion resistance is increased by 50%-200%. The steel connection strength is higher than the steel base material, and the mechanical properties of the steel joints meet and exceed domestic and foreign standards. The steel bar rolling straight thread connection technology is suitable for industrial and civil buildings. It requires the connection construction of rigid, oblique, and horizontal steel bars in important parts of the structure that give full play to the strength and ductility of the steel bars. It has a simple and fast process, can be prefabricated, has no open flame operation, does not pollute the environment, has no hidden danger of explosion and fire, is safe and reliable, can be constructed all-weather, and saves a lot of steel and energy. Only a wrench is used to connect the steel bars, and each steel bar joint takes about one minute. The construction period of the structure was shortened, and the industrialized and civilized construction was realized.

How does the rebar rolling machine work?

The threading machine is composed of: body, motor, reduction box, pipe chuck, die head, cutter holder, feed device, and cooling system.

When the threader is working, first put the rebar to be processed into the rebar chuck, hit the chuck, press the start switch, the steel bar will rotate with the chuck, adjust the size of the die opening on the die head, and set the wire The length of the mouth. Then turn the feed wheel clockwise to make the die cutter on the die head stick to the end of the rotating rebar with constant force, and the die cutter will automatically cut the tube thread, and the cooling system will automatically spray oil for cooling on the die cutter. , When the threaded mouth is processed to the preset length, the die cutter will automatically open, and the thread mouth processing is completed. Turn off the power, knock the chuck open, and take out the bar.

Precautions for using thread rolling machine

Introduction to the use of thread rolling machine

1. Adjustment before thread rolling

According to the diameter to be processed, exchange the thread rolling wheel that is compatible with the diameter to be processed. When replacing the thread roller, replace the washer that is suitable for the thread pitch of the thread roller to ensure the correctness of the thread pitch and the relationship between the thread pitch and the thickness of the washer.

2. The rolling machine should be tested empty before debugging

The thread rolling machine is turning on. Check whether the cooling water pump is working properly. Operate the button to check whether the electrical control system is working properly.

Precautions for daily maintenance of thread rolling machine

1.Due to the humidity change, the button is exposed on the contactor, so measures must be taken to prevent a short circuit in the opposite direction of the contactor.

2.Remove the dirt on the body, especially pay attention to clean the dirt between the incoming and outgoing lines to prevent short-circuit between the phases. At the same time, pay attention to clean the dirt on the surface of the iron core board.

3.When the contact is found to be severely worn and cannot be used continuously, it should be replaced with a new contact in time.
