Precautions and maintenance methods in use of plate shears

1、 Precautions for plate shears in use:

1. Start the plate shearing machine to idle for several cycles to ensure that under normal conditions, the plates of different thickness are cut from thin to thick. Ensure that the user understands the performance of the shearing machine.

2. It is necessary to adjust the gap of different blades when the plate thickness is different. If the corresponding blade gap is not adjusted, the durability of the blade will be affected.

3. Turn on the pressure gauge switch during the shearing process of the plate shearer, and investigate the pressure value of the oil circuit. The pressure shall be less than 20MPa when shearing 12mm plates. The remote pressure regulating valve No9 is set at 20-22mpa when leaving the factory. It is necessary for the user to abide by this rule. It is not allowed to increase the pressure for the data surface of the shear over rule to cause damage to the machine.

4. Sound balance during operation. If there is noise in the plate shearer, stop the machine to check.

5. During the operation of the plate shearer, the temperature of the oil tank shall be increased by less than 60 ℃ and the machine shall be shut down for rest if it is out of date.

2、 Maintenance methods of plate shears:

1. Operate in strict accordance with the operating procedures.

2. Add lubricating oil regularly, regularly and quantitatively according to the requirements of smooth chart before starting each time. The oil shall be clean and free of sedimentation.

3. It is necessary to keep the machine tool clean and unpainted.

4. The smooth oil in the motor bearing shall be replaced and filled regularly, and it is often checked whether the electrical part is normal, safe and reliable.

5. Regularly check whether the V-belt, handle, knob and key are damaged. If they are severely worn, replace them in time and report to the spare parts for compensation.

6. Check and repair the switch and handle regularly to ensure reliable operation.

7. Every day, 10 minutes before work, oil the machine smoothly and clean the machine.

8. It is forbidden to operate the equipment by non designated personnel. It is necessary to stop the equipment when people leave the aircraft.

Because of the circular arc motion of the hydraulic tilting shearing machine, and the manufacturing of the circular arc blade is appropriately difficult. Generally, the blade is used for pad iron compensation, so the resulting gap is not great, and the cut sheet material is not very ideal. Because of the arc motion, the blade can not be made into a rectangle, but should be made into an acute angle, so the stress condition of the blade is not ideal, and the blade damage is also serious.
