Blanking die structure of bending press hood

Abstract

The invention provides a blanking die structure of a bending press hood. The structure can solve the technical problems that a stripper plate is easy to abrade and short in service life,overcome the defect of proneness to center deviation of a guide pillar, and not affect the production efficiency. The structure comprise an upper die base, a lower die base, an upper die block, a lower die block and the stripper plate, wherein the upper die base and the lower die base are assembled through guiding of the guide pillar, the root of the guide pillar is arranged on and in an interference fit with the lower die base, bushes are symmetrically arranged on two sides of the stripper plate, the upper ends and lower ends of the bushes are clamped to the upper and lower edges of the stripper plate respectively, the upper portion of the guide pillar of the stripper plate penetrates through the bushes, and discharging space is reserved between the stripper plate and the lower die block during die assembly. The structure is characterized in that stripper plate inserts are symmetrically arranged on two sides of the upper die block at the bottom of the stripper plate.

Description

[0001] technical field [0002] The invention relates to a forming die structure for press brake parts, in particular to a blanking die structure for a press brake cover. Background technique [0003] During the forming process of press brake components, especially the processing of press brake covers, the working process includes: blanking, forming, and punching. The so-called blanking die structure includes upper mold base, lower mold base, guide pillar, lower module, upper module, stripping plate, stripping plate guide pillar, H7 / P6 interference fit between guide pillar and lower mold base, unloading There is a space between the material plate and the lower module, which is called the space for the arrangement of parts. The existing blanking die structure has the following other disadvantages: 1. After repeated use, the unloading plate wears quickly and has a low service life, which affects production efficiency; 2. When blanking, the lock between the guide post and th...
