[0002] In the automotive manufacturing industry, as an important component of the emission system, the processing quality of the exhaust pipe directly affects the performance and environmental protection standards of the vehicle. After the automotive exhaust pipe is processed and formed, it usually needs to be subjected to reaming treatment on one end of the exhaust pipe by a flaring die. This operation can not only simplify the installation process of the exhaust pipe, but also enable the exhaust pipe to closely cooperate with other vehicle components.
