[0002] The punch of the stamping die for the production of automotive parts is a key component of the stamping die in mechanical tools. It is mainly used for continuous blanking, stamping and breaking of automotive parts. This punch can separate or plastically deform the processed material to obtain the required automotive parts or semi-finished products.

[0003] Punches are usually made of wear-resistant and high-strength materials such as high-speed steel and cemented carbide to ensure that they can maintain sufficient durability and precision under high-load and high-frequency working environments. Their structural design is sophisticated, and their shapes and sizes are determined according to the specific automotive parts and stamping process requirements. They can be cylindrical, rod-shaped, flat-headed, ball-headed or special-shaped.

[0004] Punches are specially used to perform continuous blanking, stamping and breaking operations on stamping dies. Through direct contact with the material, the material is deformed or cut to obtain the desired finished or semi-finished product. Wear often occurs during use, which requires real-time replacement to ensure the accuracy and precision of the operation process. The traditional stamping die punch design is single, and the punch needs to be replaced as a whole when replacing it. Therefore, a stamping die punch for the production of automotive parts is proposed. The layered design facilitates later replacement and ensures stability during the operation. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a stamping die punch for the production of automotive parts, which has the advantages of good flexibility and high stability. It solves the problem that the traditional stamping die punch has a single design and the punch needs to be replaced as a whole when replaced, resulting in reduced utilization and waste of resources.

[0006] In order to achieve the above-mentioned purpose of good flexibility and high stability, the utility model provides the following technical solutions: a stamping die punch for the production of automotive parts, including a punch shell, a base component movably connected to the bottom of the punch shell, an adjustment component arranged inside the base component, and a positioning component used in conjunction with the adjustment component; the base component includes a connecting seat movably connected to the bottom of the punch shell, a positioning notch opened on the top of the connecting seat, and an exhaust hole opened inside the connecting seat.

[0014] Compared with the prior art, the utility model provides a punch for a stamping die for producing automobile parts, which has the following beneficial effects:

[0015] 1. The punch of the stamping die produced by the automotive parts is initially fixed by rotating the connecting seat into the inside of the connecting groove, and waiting for the punch shell to completely wrap the connecting position on the top of the connecting seat. Then, the adjusting seat is screwed into the inside of the hollow groove from the bottom of the connecting seat. When the adjusting seat enters to a certain depth, the adjusting wedge block on the top of the adjusting seat begins to squeeze the fan-shaped wedge block, and the fan-shaped wedge block pushes the positioning rod to squeeze the positioning arc plate and embed it into the locking groove, thereby realizing the secondary fixation of the connecting seat and the punch shell.

[0016] 2. The punch of the stamping die produced by the automotive parts can be replaced with different punch shells by rotating and unscrewing the adjusting seat. After the adjusting seat is removed from the inside of the hollow groove, the reset spring pushes the fan-shaped wedge block to begin to gather from the center of the hollow groove, and then drives the positioning rod to drive the positioning arc plate to slide out from the inside of the locking groove, and then rotate the connecting seat to unscrew it from the inside of the connecting groove to replace the punch shell. This solves the problem that the traditional stamping die punch has a single design and needs to be replaced as a whole when replacing the punch, resulting in reduced utilization and waste of resources.
