[0002] Shearing machine is a machine that shears plates by reciprocating linear motion of one blade relative to another blade. It applies shear force to metal plates of various thicknesses by using a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap, so that the plates are broken and separated according to the required size. Shearing machine is a kind of forging machine, and its main function is metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electricity, electrical appliances, decoration and other industries to provide special machinery and complete equipment required.

[0003] When shearing metal plates, shearing machines are often used. However, before current shearing machines shear the plates, workers are required to manually push the plates into the shearing opening and align the plates. Due to the manual support, one end of the plate is prone to tilt up when the cutter shears the plate, thereby causing impact on the workers' hands, causing the plates to not only shift, but also cause damage to the workers' hands.

There are two electric push rods 121, which are fixed on both sides of the top of the fixed plate 11. The output end of the electric push rod 121 is fixed to the top of the pressure plate 122. There are several first round rollers 123, which are rotatably connected to the bottom of the pressure plate 122. In this way, when the plate is pressed, the electric push rod 121 can be started and the pressure plate 122 can be driven to move downward, so that the first round roller 123 contacts the top surface of the plate to avoid warping when the plate is cut.

[0025] The driving structure 18 includes a third motor 181, a second gear 182 and a third gear 183. The third motor 181 is fixed to the top of the rack plate 15.
