Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die that is easy to replace the stamping die head. Background Technology

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

[0003] A stamping die head is a metal part mounted on a stamping die, commonly called a punch or punch. The main function of a punch is to perform operations such as blanking, punching, or forming on the material during the stamping process, causing the material to separate or plastically deform, thereby obtaining the desired finished or semi-finished product.

[0004] Patent document CN217798462U discloses a stamping die that facilitates the replacement of the stamping die head, including a base. A lower template is provided on the base surface of the base, and a support plate is provided on the upper side of the base. Limiting slide rods are provided at the corners of the bottom of the support plate and between the support plate and the base surface of the base. A driving cylinder is provided in the middle of the base surface of the support plate. The driving end of the driving cylinder passes through the support plate and is provided with an upper template. A buffer spring is sleeved on the outer wall of the limiting slide rod and located on the lower side of the upper template. Through the provided fixed rod, fixed ring, pull button and fixed spring, the fixed rod can be moved by pulling the pull button, so that the fixed rod can be pulled out from the connecting hole, so that the mounting plate is not connected to the upper template, thereby allowing the stamping die head to be disassembled and replaced. The installation and disassembly are relatively convenient, making replacement more convenient.

[0005] As in the prior art of the aforementioned patent, when replacing the stamping die head, the stamping die head needs to be replaced in the space below the support plate. However, the location and space of the stamping die head are small, making replacement inconvenient. Furthermore, the die head is only fixed inside the mounting slot by a fixing rod on one side, making it difficult to fix the die head and resulting in a lack of stability during subsequent stamping processes.
