[0002] 3D cutting and punching die is an efficient tool for cutting and punching materials, which is widely used in the manufacturing industry. It is usually made of carbide material to ensure the durability and precision of the tool.

[0003] A stamping die is a metal processing tool that is mainly used to stamp metal materials into parts of specific shapes and sizes. A stamping die usually consists of two upper and lower templates. The upper template is usually equipped with a male and female die, while the lower template is equipped with a corresponding die base. During the stamping process, the upper template moves downward, and the male and female dies interact with the die base to cause plastic deformation of the metal material, thereby obtaining the desired parts.

[0004] The prior art discloses a cutting and stamping die with limit protection, application number: CN202121885867.1, including a template, a plurality of knife rings are installed in the upper surface of the template, spring assemblies are installed in the two corners of the template, and the two spring assemblies are symmetrical with the center of the template. The spring assembly includes a connecting tube and a spring. A connecting groove is provided inside the template near the spring assembly, and a bolt is installed inside the connecting groove.
