Problems solved by technology

[0004] However, when the existing shearing machine cuts the metal sheet, it is easy to cause serious deformation of the metal sheet in the shearing area, which not only reduces the strength of the edge area of ​​the metal sheet, but also seriously reduces the requirements for aesthetics and size. Secondary treatment is required, which is time-consuming and labor-intensive, resulting in very low processing efficiency

Abstract

The invention discloses a self-balancing type metal plate shearing device and belongs to the technical field of plate shearing. Through the self-balancing type metal plate shearing device, a metal plate in can be sheared in a single direction in a mode that a cutter holding groove is formed in a working surface, and the plate is shaped and supported in the cutter holding groove by virtue of a self-supporting ball and a pre-supporting block. After a blade cuts the plate and the pre-supporting block by depending on sharpness, the pre-supporting block is rapidly melted firstly, then the half partof the self-supporting ball is extruded, the self-supporting ball is forced to deform to achieve self-filling supporting on the plate, released magnetorheological fluid is rapidly hardened under theaction of a magnetic field, good shaping supporting on the plate is achieved, and serious deformation is not prone to occurring. Compared with the prior art, the shearing error within a certain rangeis allowed, the self-supporting ball can automatically adapt to shearing of the blade to achieve attaching supporting, the shearing difficulty can also be reduced in the mode that the blade is subjected to heat treatment, and the shearing effect on the metal plate is comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of plate shearing, and more specifically relates to a self-balancing metal plate shearing device. Background technique [0002] In the production process of sheet metal, the sheet metal used in some industries has certain requirements for its thickness and length. In order to meet the supply requirements of such sheet metal products, it is necessary to cut the length of the long roll sheet metal produced. During the cutting process, it is necessary to straighten and inspect the surface quality of the long coils to prevent unqualified products from entering the market. [0003] The shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to the other blade to cut the plate. It uses the moving upper blade and the fixed lower blade to apply shearing force to metal sheets of various thicknesses with a reasonable blade gap, so that the sheets are broken and separated accor...
