[0002] As an important part of the metal processing field, the technical development of metal pipe stamping technology has always revolved around the core goals of improving production efficiency, ensuring product accuracy and reducing costs. Traditional metal pipe stamping dies mostly adopt an integral structure. Although this design is compact, it has many inconveniences when replacing and maintaining the mold, such as long mold replacement cycle, high cost, and difficulty in adapting to the processing needs of pipes of different sizes. In recent years, with the improvement of the level of automation in the manufacturing industry, modular and adjustable mold assembly structures have gradually become a research hotspot. This type of design allows the mold to be quickly adjusted to adapt to a variety of product specifications, significantly improving production flexibility.

[0003] However, the existing die assembly structure for stamping dies still faces some challenges. First, the stability and reusability of the connecting parts are one of the key issues. Many existing designs rely on welding connections, which not only limits the rapid disassembly and assembly of the die, but also easily leads to a decrease in accuracy due to wear after long-term use. It is not easy to replace parts separately. Therefore, we propose a die assembly structure for metal pipe stamping. Utility Model Content
