Mechanism for buffering pressure during punching occlusion of automobile rear silencer shell

Abstract

The invention discloses a mechanism for buffering pressure during punching occlusion of an automobile rear silencer shell. The mechanism comprises an upper positioning base (1), a lower positioning base (2) and an upper punching rod (5), a positioning pipe (4) is arranged at the upper end face of the lower positioning base (2), a connecting pipe (3) corresponding to the positioning pipe (4) in position is arranged at the lower end face of the upper positioning base (1), the upper end of the upper punching rod (5) is embedded in the connecting pipe (3), a punch head (6) arranged on the upper punching rod (5) in a sleeved mode is arranged at the lower end of the upper punching rod (5), the punch head (6) corresponds to the positioning pipe (4) in position, a spring (7) winds the upper punching rod (5), and the two ends of the spring respectively act on the connecting pipe (3) and the punch head (6). By means of the structure, the mechanism is simple in overall structure and convenient to implement, and when the mechanism is applied, the action force between an upper pressure-application die and a lower pressure-bearing die can be buffered, and then the upper pressure-application die and the lower pressure-bearing die which are connected to an automobile rear silencer shell in a pressing mode are protected.

Description

technical field [0001] The invention relates to auxiliary equipment in the production line of the automobile rear muffler, in particular to a mechanism for cushioning the pressure when the casing of the automobile rear muffler is stamped and engaged. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the use of cars is also increasing. While automobiles are convenient for people's daily life, the noise generated during the exhaust process has also become the main source of noise in today's noise pollution. In order to reduce the noise pollution produced by automobiles, mufflers are all provided on today's automobiles, so the production of mufflers has increased dramatically. [0003] In order to facilitate core loading, the muffler cylinder of the automobile rear muffler includes upper and lower shells. After the core is installed, the upper and lower shells are crimped by pressing to complete...

AI Technical Summary

Problems solved by technology

Nowadays, in the process of pressing the muffler cylinder of the automobile rear muffler, when the upper pressure-applying mold and the lower pressure-bearing mold are in contact, the interaction force between the two is relatively large, which easily leads to the upper pressure-applying mold and the lower pressure-bearing mold. The pressure-bearing mold is damaged, and the replacement mold is expensive and takes a lot of time and effort
