Plate stamping device

Abstract

The invention discloses a plate stamping device. The stamping device comprises a stamping platform, an upper die fixing part is arranged on the stamping platform in a sliding manner, an upper die is installed on the upper die fixing part, a lower die is installed on the stamping platform, a hydraulic cylinder is fixed to the stamping platform, and an output shaft of the hydraulic cylinder is fixed to the upper die fixing part. Limiting pieces which are symmetrically distributed are arranged on the upper die fixing part and the stamping platform in a sliding manner, the limiting pieces on the upper die fixing part are located on the upper die fixing part and clamped on the upper die in a sliding manner to limit the upper die, and the limiting pieces on the stamping platform are located on the stamping platform and clamped on the lower die in a sliding manner to limit the lower die; and supporting pieces distributed in an array manner are installed on the lower die, first elastic pieces are connected between the supporting pieces and the lower die, and a driving piece used for jacking up the supporting pieces is fixed to the stamping platform. According to the stamping device, the supporting pieces are jacked up through the driving piece, and the problem that a plate is not easy to take out after stamping is solved.

Description

technical field [0001] The invention relates to the field of plate stamping, in particular to a plate stamping device. Background technique [0002] Stamping forming refers to the process of applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of required shape and size. It is processed by stamping. [0003] In the existing sheet metal stamping process, neither the upper mold nor the lower mold can be quickly disassembled, which makes the efficiency of sheet metal stamping low, and there is a problem that the sheet is not easy to take out after stamping. Contents of the invention [0004] The object of the present invention is to provide a sheet metal punching device. By pulling the limiting member, the limiting shaft is drawn out from the limiting groove, and the engaging block is engaged in the engaging groove by rotating the engaging member to fix the l...

Problems solved by technology

[0004] The object of the present invention is to provide a sheet metal punching device. By pulling the limiting member, the limiting shaft is drawn out from the limiting groove, and the engaging block is engaged in the engaging groove by rotating the engaging member to fix the limiting member. Take out the upper mold or the lower mold to realize the rapid disassembly of the mold of the stamping device, and lift the supporting piece through the driving part, which solves the problem that the plate is not easy to take out after stamping
