Problems solved by technology

[0003] Making the metal thin plate test piece into a standard single-piece sample requires four-sided shearing, and the existing shearing machines are all for large steel plates and steel coils with standardized raw material sizes. If the existing shearing machine is used to shear metal For thin plate test pieces, at least two clamping and positioning are required, the work efficiency is very low and the shearing accuracy will be affected

Abstract

The invention discloses a metal sheet shearing machine, which comprises a rack, a shearing mechanism arranged on the rack, a material pressing mechanism and a feeding mechanism, wherein the shearing mechanism comprises a shearing hydraulic cylinder arranged on the top of the rack, a front end shearing device arranged at the front end of the rack, and a left shearing device and a right shearing device correspondingly arranged at the left side and the right side of the rack, the front end shearing device, the left shearing device and the right shearing device respectively comprise an upper tool carrier connected with the shearing hydraulic cylinder and a lower tool carrier fixed on the rack, and the upper tool carrier and the lower tool carrier are correspondingly provided with blades; the material pressing mechanism comprises a material pressing hydraulic cylinder arranged on the top of the rack and a material pressing device connected with the material pressing hydraulic cylinder, and the material pressing device is positioned behind the front end shearing device and between the left shearing device and the right shearing device; and the feeding mechanism can be arranged at the rear end of the rack in a back and forth reciprocating mode. The metal sheet shearing machine can complete four-side shearing in the state of one-step clamping, has high working efficiency and is safe and reliable.

Description

technical field [0001] The invention relates to a shearing device, in particular to a metal sheet shearing machine. Background technique [0002] In the research and development process of some new products of metal sheets, the metal sheet test piece is obtained after a series of processes such as smelting, hot rolling, cold rolling, heat treatment, etc., and then the metal sheet test piece is cut into a standard single piece of specified size Samples, in order to use the Epstein square circle to detect its magnetic parameters or conduct other tests. Through trial and error, new products that meet actual needs are obtained. The traditional standard single-piece sample manufacturing method is completed by die punching, but this method will generate shear stress on the edge of the test piece, which will affect the accuracy of the magnetic measurement of the test piece, and the unevenness and unevenness of the test piece Standardization makes the filming operation inconvenien...
