The oil pressure is not smooth, resulting in abnormal shear

Hydraulic oil condition check

Sufficient oil: Ensure that the oil in the hydraulic tank meets the specified standard, and replenish it in time when it is insufficient.
Good oil quality: check hydraulic oil color, viscosity, impurity content, etc., if there is deterioration, pollution or emulsification, should be replaced with qualified new hydraulic oil.

Hydraulic pump and accessories inspection

Working state of hydraulic pump: Observe whether the operating sound and vibration of hydraulic pump are normal, no noise, overheating and other abnormal conditions. Check whether the oil suction port of the pump is smooth, no blockage, air leakage phenomenon.
Oil filter cleaning: clean or replace the oil filter to ensure that the oil filtration effect is good and no large amount of impurities enter the hydraulic system.

Hydraulic valve group inspection:

Valve body working status: check the hydraulic valve (such as direction valve, pressure valve, flow valve, etc.) is working normally, no stuck, leakage and other phenomena. Operate the handle or electronic switch to ensure that the valve is responsive and without hysteresis.
Pressure regulation setting: According to the equipment manual, check whether the pressure valve setting corresponding to the shear action is correct, and adjust it if necessary.

Hydraulic pipeline and joint inspection:

Smooth pipeline: Check the hydraulic pipeline without bending, extrusion, damage, to ensure that the oil flow is unimpeded. Clean up possible impurities and rust inside the pipe.
Joint fastening: Check all hydraulic joints to ensure that there is no loosening or oil leakage. Use a torque wrench to tighten to the specified torque.

Hydraulic cylinder and seal inspection:

Hydraulic cylinder action: Observe whether the shear hydraulic cylinder expansion is smooth, no crawling, abnormal sound and other phenomena. Check that the piston rod is not scratched, bent, and the seal is not aging or damaged.
Replace the seal: If the seal is found to be seriously worn or leaking, replace the new seal in time.

Check the control system:

Electrical wiring: Ensure that the electrical wiring of the control hydraulic system is not loose, damaged, and in good contact.
Electronic control unit: Check whether the electronic control unit (such as PLC, relay, solenoid valve, etc.) works normally, no fault alarm. Make necessary parameter Settings or program adjustments according to the equipment manual.

Machine debugging:

No-load test run: After eliminating the above faults, carry out no-load test run to observe whether the hydraulic system pressure, flow and other parameters are normal, and whether the shear action is smooth.
On-load test: After the no-load test runs normally, the on-load test is carried out to verify the working performance of the shear function under actual conditions.

Press tile machine deviation problem, edge grinding paint

Check the roughness of raw materials:

Raw material quality: Ensure the use of color steel coil, galvanized sheet and other raw materials flatness is good, no warping, wave edge and other defects.
Raw material end treatment: when feeding, the raw material end should be properly trimmed to avoid deviation due to uneven end.

Guide device adjustment:

Side guide plate: Check whether the gap between the two sides of the guide plate and the edge of the raw material is uniform, and there is no obvious deviation. Adjust the guide position as needed to ensure that the material remains centered during operation.
Front and rear guide posts: Check whether the front and rear guide posts are perpendicular to the direction of the raw material without tilt. If there is deviation, correct it.

Roller pressure adjustment:

Upper and lower rollers: According to the thickness of raw materials, hardness and other factors, adjust the pressure of the upper and lower rollers to ensure that the raw materials are evenly stressed between the rollers, and no unilateral force is too large to cause deviation.
Correction roller: If the equipment is equipped with correction roller, check its working status to ensure that it can effectively correct the slight deviation of raw materials.

Transmission system inspection:

Transmission chain: Check whether the tension of the transmission chain is appropriate, no slack, fracture phenomenon. Adjust the chain tensioning device to keep the chain tension constant during operation.
Drive shaft, bearing: Check whether the drive shaft, bearing and other transmission parts are worn, loose, no noise, heat and other abnormal conditions. If there is a problem, timely replacement or repair.

Check the control system:

Electronic control unit: Confirm that the electronic control unit (such as PLC, inverter, etc.) works normally, no fault alarm. Check whether the related parameters are set correctly, such as speed, acceleration and deceleration time.
Deviation correction system: If there is an automatic deviation correction device, check its working status, such as the sensor, the actuator, etc., is normal. Adjust the correction parameters as required to improve the correction effect.

Machine debugging:

No-load test run: After eliminating the above faults, carry out no-load test run to observe whether the raw materials run in the equipment is centered, and there is no obvious deviation.
On-load test: After the no-load test operation is normal, the on-load test is carried out to verify the working performance of the deviation correction function under actual conditions

Press tile machine counting wheel does not count how to do

Check the power supply and connection: Confirm the power supply, check the fuse or circuit breaker
Check the hardware of the counting wheel: appearance and mechanical damage, sensor status
Check the electrical connection: wire connection, interface plug
Check the control system Settings: count parameters, count function is enabled
Software failure or compatibility problem: control system software, communication protocol
Electromagnetic interference: Environmental electromagnetic interference, poor grounding
Reset or initialization: the counting wheel is reset and the control system is restarted

The reason why the two pinion gears behind the lifting knife edge of the tile press machine will beat when there is a lifting is the gear wear

Check gear wear
Adjust the assembly accuracy
Improve lubrication
Check the transmission system
Tighten the structural parts

Enter a number and press to confirm.

First troubleshoot operational errors and hardware failures, then check software Settings and storage media, and finally consider power and communication factors. If the problem is complex or difficult to solve, contact the device manufacturer or technical personnel for diagnosis and maintenance.

What is the reason for the inaccurate encoder count:

Usually from the most intuitive connection, installation, pollution, etc., and then to hardware failure, software Settings, electromagnetic interference and other in-depth issues. If necessary, professional technicians may be required to carry out inspection and repair, or to replace faulty parts. At the same time, regular equipment maintenance and calibration can prevent the occurrence of such problems.

What happened when the display did not light up

From the power supply, connection, display itself, video signal, host control and other angles to gradually check. In the case of inconclusive self-examination, it is recommended to contact the equipment manufacturer or professional maintenance service for further diagnosis and repair.

There is a lot of difference between the actual length and the set length, a difference is one or two meters, not a few centimeters

In this case, it is necessary to adjust the pulse in the program of the tile press

before the count is accurate, later with the use of the error, and the difference is the same

This situation is the counting wheel is not correct, wear caused by fast. Look at a few meters of thin wheel and plate contact point is not flat contact, the left and right need to be parallel, vertical up and down

Most of them are accurate, and occasionally one or two are too long or too short

Raw material problem: uneven quality of raw materials;
Improper equipment adjustment: mold wear or installation deviation, pressure adjustment is not appropriate;
Process parameter setting: speed setting is unreasonable, temperature control is not accurate;
Operation error: uneven placement of raw materials, abnormal equipment is not handled in time;
Maintenance is not in place: insufficient lubrication, cleaning is not in place;
