Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die which is convenient for replacing a stamping head. Background Art

[0002] Stamping dies are special process equipment used to process materials into parts during cold stamping. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts.

[0003] For example, the Chinese authorized patent with announcement number CN217912495U (a stamping die with a replaceable stamping die head): comprises an upper die and a lower die at the bottom of the upper die, the top surface of the upper die is provided with a slot, the inside of the slot is connected with a screw, the lower end of the screw is connected with a punch, the top surface of the punch is connected with a bump, and the surface of the bump is connected with a spring. When the stamping die with a replaceable stamping die head is used, the stamping die first uses a screwdriver to disassemble the screw in the slot on the surface of the upper die, and then completely separates the screw from the punch, and then the force spring is subjected to an elastic force, thereby driving the bump to form an elastic force on the punch, so that the bump squeezes the punch, so that the punch quickly separates from the tight connection with the upper die, and then the punch can quickly separate from the groove, so as to achieve the purpose of easy replacement.

[0004] However, the punching heads of the existing stamping dies are mostly fixed by screws, and tools are needed to operate when disassembling and replacing them, which is time-consuming and labor-intensive; therefore, it does not meet the existing needs. In this regard, we propose a stamping die that is easy to replace the punching head. Utility Model Content
