Background

Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation thereof, thereby obtaining a desired part. The stamping die is a special technological device for processing materials into parts in the stamping process.

The traditional Chinese patent with the publication number of CN202789036U discloses a catalyst inlet end cone, which comprises an inlet end cone body, wherein an oxygen sensor hole is formed in the inlet end cone body, and two 8-shaped interfaces are symmetrically arranged on the inlet end cone body.

Compared with the traditional four-interface air inlet end cone structure, the 8-shaped interface on the air inlet end cone reduces two punching processes and two welding processes, and simplifies the process steps. Therefore, in the manufacturing process of the air inlet end cone, the number of punched holes completed by one-time punching process is one, and the air inlet end cone needs to be placed on other punching dies for processing when other holes are punched.

However, because the machining precision requirement of the distance between the holes on the air inlet end cone is higher, after the air inlet end cone is placed on other dies to be clamped and machined, the distance between the holes may deviate greatly, the precision requirement cannot be met, and the defects are obvious.
