Problems solved by technology

[0002] Automobile exhaust system refers to the system that collects and emits exhaust gas. It is generally composed of exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, automobile muffler and exhaust tailpipe. Oil system, ignition system and other faults, engine overheating, tempering, resulting in three-way catalytic converter carrier sintering, peeling off, exhaust resistance increases, therefore, the bracket connected to the exhaust system needs to bear a certain pressure, the existing car engine The connecting bracket is manufactured by assembly or stamping process, which saves the production cost, but the stability performance is poor, and the size of the support frame holes is not uniform, which is not convenient for parts replacement
