Description

Pressure-pulling device for producing exhaust connecting pipe Technical Field The utility model relates to the technical field of production of exhaust connecting pipes, in particular to a pressing and pulling device for production of exhaust connecting pipes. Background The exhaust connecting pipe is used as a key part of a plurality of devices, has extremely wide application fields and plays an indispensable role in the industries of automobiles, aerospace, industrial devices and the like. Taking the automobile industry as an example, the exhaust connecting pipe is an important component of an automobile exhaust system, and the performance of the exhaust connecting pipe directly influences the exhaust emission effect, the power performance and the riding comfort of a vehicle. With the increasing strictness of environmental regulations and the increasing demands of consumers on vehicle performance, automobile manufacturers put higher standards on the quality and performance of exhaust connection pipes.
