[0002] Cars are a very common means of transportation in modern daily travel. Since the C-pillar in a car mainly plays a supporting and protective role, the strength requirements of the car's C-pillar are relatively high. During the processing of the car's C-pillar, a reinforcement stamping die is generally used to assist in completing the stamping of the car's C-pillar.

[0003] Before stamping, the existing automobile C-pillar reinforcement stamping die needs to place the stamping material in the mold cavity of the bottom mold, and then start the hydraulic cylinder to drive the upper mold to stamp to complete the stamping process of the automobile C-pillar reinforcement. However, the stamping material needs to be adjusted by the staff before placement to ensure that the stamping can be correctly formed. Manual adjustment of the position is troublesome and time-consuming. In addition, during the stamping process, if the material is slightly misaligned, it will also cause defects in the C-pillar reinforcement.

[0004] Therefore, it is necessary to provide a new automobile C-pillar reinforcement stamping die to solve the above technical problems. Utility Model Content
