Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to a hydraulic swing type plate shearing machine. Background Art

[0002] Shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear the plate. It uses the moving upper blade and the 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.

[0003] Compared with ordinary shearing machines, swing shearing machines mostly use oblique blade shearing. They are widely used due to their simple structure, low failure rate, high shearing efficiency and no bowing, warping or twisting of the plates after shearing. However, the feeding of swing shearing machines is generally done manually by workers, with poor accuracy and high workload. The plates are pressed only during shearing, which is dangerous. The sheared plates fall into the inside of the shearing machine, requiring workers to enter the inside of the shearing machine to pick them up after shearing, which is inconvenient. Therefore, we propose a hydraulic swing shearing machine. Utility Model Content
