[0002] In the color steel plate production line, hydraulic shears are often arranged between the uncoiler and the tile press. The function of the hydraulic shears here is to cut the steel coil to facilitate operation when work needs to be stopped, such as changing the plate type, changing shifts, etc.

[0003] In order to meet the needs of hydraulic scissors shearing operations, the current technology in actual applications uses brass plates as limit guide blocks and cooperates with grease lubrication to meet the requirements. However, it can only meet application scenarios where shearing operations are not frequent. In certain special working conditions, frequent shearing operations are required, and the brass plates used for limit guides will be worn quickly, which will cause gaps between the upper and lower blades, which will greatly shorten the service life of the equipment.

[0016] In the above-mentioned hydraulic plate shearing device, the slider is fixed to the upper blade seat by bolts;

[0017] The linear guide rail is fixed to the adjustment plate by bolts;
