[0002] In the cold stamping process, a special process equipment is used to shape metal or non-metal materials into parts or semi-finished products. This equipment is called a cold stamping die, usually referred to as a cold stamping die. Cold stamping is a pressure processing technology that applies external force to the material through a die installed on a press at ambient temperature, causing the material to break or plastically change to form the required parts.

[0003] In some cases, the existing cold stamping dies can perform stamping and punching at the same time. For example, in the stamping production process of the door sill reinforcement plate of the car, the first order can be blanking and punching at the same time. However, in other special cases, in order to meet specific process requirements and product quality, stamping and punching need to be performed separately. For example, in the stamping process of the rear floor of the car, stamping needs to be performed first, and then the punching process, but the two processes need to be set up in two separate stations, which reduces the production efficiency. Therefore, the market urgently needs a flip stamping die for the rear floor of the car to solve the above problems. Summary of the invention
