Abstract

The invention relates to a ridging die for a damping package inner assembly of a vehicle exhaust system. The ridging die comprises a ridging assembly and a clamping tool assembly, wherein the ridgingassembly comprises a ridging movable plate, positioning rings, pull rods, a ridging fixed plate, outer sleeve rods, positioning mechanisms, cone rods, clamping and locking die bodies and end clampingheads, and the clamping tool assembly comprises a tool base plate, tool fixed plates, tool movable plates, pipe fitting positioning blocks, profiling plates, guide pillars, guide sleeves, oil cylinders, oil cylinder connecting rods and floating joint bases. By means of the ridging die, part of metal of a damping pipe is stretched and deformed, and the inner assembly assembling process of fixing two parts of a clapboard and the damping pipe is achieved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a ridge mold of an inner component of a muffler package of an automobile exhaust system. Background technique [0002] Continuous improvement of product quality is the foundation of enterprise growth. Improve the competitiveness of enterprises in the same industry by continuously improving product quality. The clapboard and pipe fittings of the components in the traditional sound-absorbing package adopt welding process, which is prone to welding slag and the risk of welding penetration, and the welding slag needs to be manually removed after welding. Now adopting the ridge process, the surface is smooth, free of welding slag, welding lumps, and no risk of weld penetration of pipe fittings. Contents of the invention [0003] The purpose of the present invention is to improve the problem of abnormal sound of the sound-absorbing bag caused by welding slag and weld spall falling o...
