Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to a plate pressing device used for plate shearing machines. Background Art

[0002] A shearing machine is a machine that uses one blade to make reciprocating linear motion relative to another blade to shear plates. It uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size. A shearing machine is a type of forging machinery, and its main function is in the metal processing industry. At present, the plate pressure columns used in metal shearing machines are mostly welded on the bracket, and the bracket is supported by a spring. When the shearing machine allows the bracket to drive multiple pressure columns to apply pressure to the plate and compress the plate at the same time, the horizontal accuracy of the pressure columns is high. When the height of the bottom end of the pressure column is different, the higher pressure column is difficult to fit the plate, which will reduce the clamping effect on the plate and the plate is easy to loosen.
