Brake pad steel backing precision stamping die assembly

Abstract

The invention belongs to the technical field of stamping manufacturing, and particularly relates to a brake pad steel backing precision stamping die assembly. According to the main technical scheme, the assembly is mainly composed of an upper die with a puncher pin and a lower die with a female die; the upper die comprises an upper die base plate and an upper die mounting bottom plate connected with the upper die base plate, the upper portion of the upper die base plate is used for bearing downward precision stamping pressure, the puncher pin is arranged on the lower portion of the upper die mounting bottom plate through a puncher pin mounting plate, the lower die comprises a lower die base and a lower die base plate connected with the lower die base, the female die is arranged on the upper portion of the lower die base plate through a die locking sleeve plate, a cavity in the female die vertically corresponds to the puncher pin, and a puncher pin device capable of stamping a sinking hole in a steel backing to form a convex pin is sleeved with the upper die, and the precision stamping die assembly has the beneficial effects of being easy to operate and capable of carrying out multiple procedures at the same time.

Description

technical field [0001] The invention belongs to the technical field of stamping manufacturing, and in particular relates to a steel back fine-blanking die assembly for a brake pad. Background technique [0002] Automobile friction brake brake pad is an extremely important part in the automobile braking system. It is generally composed of a steel back bonded with a heat insulating layer and a friction block. The purpose of the steel back is mainly to fix the friction material and facilitate installation on the braking system. Therefore, the stamping quality of the steel back directly determines the use effect of the brake pad. The traditional steel back stamping process includes blanking, punching and sinking to form convex nails, leveling, root cleaning, fine scraping and other independent processes. The manufacturing cycle is long and the production efficiency is not high; due to incoherent production steps, The integration level of the processing link is low, requiring a ...
