Requirements and precautions for shearing machine in operation

Correct operation of the shearing machine is the premise of ensuring safety, because the blade of the shearing machine is very sharp, if there is a mistake in operation, it will cause danger. In order to ensure that you are not injured when operating the shearing machine, you must follow these basic operating points and precautions when operating the shearing machine.

How to use the hydraulic shearing machine is a must for those who use the machine for the first time. If you do not master it well, you may not be able to use the hydraulic shearing machine well. , resulting in various problems, thus affecting the normal operation of the shearing machine. As for the hydraulic pendulum shearing machine, today we will introduce its operating procedures. We have already understood how it operates, and today's operating procedures are perfect.

When using the hydraulic shearing machine, start the hydraulic shearing machine blade machine for several cycles to ensure that under normal circumstances, the trial shearing of different thicknesses from thin to thick, to ensure that the user is familiar with the hydraulic shearing machine blade performance. Different blade gaps must be adjusted for different plate thicknesses during trial shearing. If the corresponding blade clearance is not adjusted, the blade durability will be affected.

The blade of the hydraulic shearing machine opens the pressure gauge switch during the shearing process, and observes the pressure value of the oil circuit. When cutting a 12mm plate, the pressure should be less than 20MPa. When leaving the factory, the pressure is set at 20-22MPa, and the user must abide by this regulation. It is not allowed to increase the pressure for shearing the surface of the material that exceeds the specified limit, causing damage to the machine. The sound is balanced during operation. If there is noise on the blade of the hydraulic guillotine shearing machine, it should be stopped for inspection. Fuel tank temperature rises during blade operation of hydraulic guillotine shears

The operating procedures of the hydraulic pendulum shearing machine, before the work, before the dry running test, should be manually cranked for a working stroke, and the equipment can be started only after confirming that it is normal. Equipment with hydraulic devices, check the oil volume of the oil storage tank should be sufficient. After starting the oil pump, check whether there is leakage in the valve and pipeline. The pressure should meet the requirements. Open the air valve to release the air in the system.

During work, it is not allowed to cut the laminated sheet, trim the edge of the raw sheet, and cut the narrow sheet and short sheet that cannot be pressed tightly. The gap between the blades should be adjusted according to the thickness of the plate, but should not be greater than 1/30 of the maximum plate. The blade should be fastened firmly, and the upper and lower blade surfaces should be kept parallel. After adjustment, manual turning inspection should be used to avoid accidents. The cutting edge of the blade should be kept sharp. If the cutting edge becomes dull or cracked, it should be replaced in time. When cutting, the pressing device should firmly press the sheet, and it is not allowed to cut in a state where it is not pressed tightly.

For equipment with hydraulic devices, other than throttling and cutting, other hydraulic valves are not allowed to be adjusted without permission. For the thickness of the sheet sheared by the hydraulic pendulum shearing machine, it should be determined according to the 'Relationship Curve of Sheet Ultimate Strength and Plate Thickness'. After work, the upper blade should be placed in the lowest position.
