Metal plate shearing die

Abstract

The invention discloses a metal plate shearing die. The metal plate shearing die structurally comprises an upper die plate and a lower die plate, wherein the upper die plate comprises an upper die plate seat and an upper die fixed plate, the upper die fixed plate is fixedly connected to the surface of the upper die plate seat, an upper die anti-side block, an upper die cutting edge and an upper die pressing plate are arranged on the upper die fixed plate in sequence, and guide sleeves are arranged on both ends of the upper die fixed plate; the lower die plate comprises a lower die plate support frame bottom plate, a lower die support frame and a lower die plate seat, the lower die plate seat is fixedly connected to the lower die plate support frame bottom plate by virtue of a lower die plate support frame, a support plate, a lower die cutting edge adjusting block, a lower die cutting edge and a sliding plate are arranged on the lower die plate seat in sequence, a plate positioning device and a plate pulley are arranged on the support plate, guide posts are fixedly arranged on both ends of the lower die plate seat, and upper die support mechanisms are arranged on both sides of the guide posts. The metal plate shearing die has the advantages of high shearing precision and durability of the cutting edges and can be used for shearing the plate with the width of 300 to 450 mm.

Description

technical field [0001] The invention relates to the technical field of cutting devices, in particular to a sheet metal shearing die. Background technique [0002] Laser welding technology has the advantages of high power density, fast energy release, high work efficiency, and its own smaller focus point, which makes the adhesion between the stitched materials better and will not cause damage and deformation of the materials. It is widely used in manufacturing industry. At present, most of the metal cylinders are manufactured by laser welding technology. However, because the laser welding technology has higher requirements on the slump angle, straightness and verticality of the sheet metal, it increases the difficulty of cutting the sheet metal. [0003] In the prior art, sheet metal is usually cut using a shearing machine and a shearing die. After cutting with a shearing machine, the sheet metal is bent and has serious collapse angles, and the qualified rate of the sheet ...

AI Technical Summary

Problems solved by technology

After cutting with a shearing machine, the sheet metal is bent and has a serious collapse angle, and the qualified rate of the sheet metal is low

In the process of using the shear die punching of the prior art, because the upper die and the lower die of the shear die will be separated quickly after punching, there is a certain deviation in the size of the plate that has just been punched. A large amount of waste will also be generated in the process, which will increase the production cost
