AI Technical Summary

Technical Problem

Existing buffer bracket processing suffers from problems such as fragmented processes, large dimensional deviations, low production efficiency, and severe welding deformation, making it particularly difficult to meet the high-quality, mass production needs of complex structures such as bending, forming, and spring hooks.

Method used

The progressive die is processed using a buffer bracket. Through reasonable layout design and coordinated multi-station layout, the part can be formed in one step, continuously stamped and stably stripped. This includes the synchronous processing of multiple functional stations, especially the synchronous processing of positioning holes and hooks, to ensure accuracy.

Benefits of technology

It significantly improved production efficiency and product precision, ensured the stability of weak structures, and enhanced processing efficiency and product consistency.

Abstract

The application relates to a buffer support machining progressive continuous die for machining a buffer support provided with positioning holes, mounting holes and hooks, which can simultaneously machine two pieces of left-right symmetrical buffer supports, and sequentially comprises a first punching station section for machining the mounting holes, a second punching station section for synchronously machining the positioning holes and hook groove sections, a peripheral blanking station section, a bending forming station section and a cutting station section along a machining direction, the positioning holes and the hook groove sections are synchronously machined, so that the precision of the hooks relative to the positioning holes of the finished buffer support can be accurately controlled.
