1. Analysis of punching structure of precision metal stamping die

Precision metal stamping molds are frequently used in practical equipment applications. The punching block structure of traditional precision metal stamping molds mainly adopts direct processing or directly stamping corresponding small holes on the template. In the process of improving and optimizing its punching structure, its structure is mainly embedded into the original template. The deep processing of punching structures is mainly due to the difficulty of traditional mold production processes, which require disassembling the entire mold. This not only wastes a lot of manpower and material resources, but also causes a significant waste of maintenance costs if problems occur. By adopting a new punching structure, the overall structural model can be improved, effectively avoiding the problem of blade wear during punching operation. The overall operation and maintenance system can be smoothly upgraded to achieve large-scale production and replacement, improving the overall equipment operation efficiency.

2. Improvement analysis of punching structure for precision metal stamping molds

After the improvement of the punching structure of precision metal stamping molds, it is necessary to change the original block structure to a two-piece structure, that is, to separately adjust the structure of the punching edge to a T-shaped circular structure, in order to ensure that the entire equipment has high application value. After improvement, the replacement of the equipment only requires dismantling and installing the structure of the small hole insert, which not only saves time but also makes the replacement operation of the small hole blade more convenient. In addition, in the application process of the T-shaped circular structure of precision metal stamping die punching structure, the processing operation is also time-saving and labor-saving, only requiring disassembly, cutting and processing of small hole inserts, which can shorten the processing time to a certain extent. The T-shaped structure of the new structure can be made into standard parts, mass-produced, and stored in the spare parts warehouse for future use. In short, the T-shaped circular structure of the new structure saves more overall materials and maximizes cost savings compared to the old structure.

And the specific improvement process: ① Combining traditional structural design with the style of new small hole embedded block structure, and effectively optimizing different unit molds according to actual situations to ensure that the drawings are designed after comprehensive analysis on the original basis. ② In the design process, relevant designers should separately divide the small hole processing part and ensure that the small hole insert structure and sheet metal processing parameters meet the actual requirements. Especially for T-shaped circular inserts with small hole structures, sheet metal treatment was carried out, and the material of the raw materials was analyzed in detail. Generally, small hole inserts are made of hard materials, molds are made of Cr12MoV, and T-shaped circular inserts are made of GBD-2. After the design is completed, centralized procurement of raw materials is carried out to ensure that the rough machining drilling operation can meet the thread requirements. ③ Heat treat it to maintain a hardness of HRC58-60, with a focus on the flatness of the entire small hole insert after heat treatment, and control its size between 0.02~0.03mm. In addition, technicians should pay special attention to wire cutting processing, strictly control the gap between the insert and the template, and ensure that the gap between the T-shaped circular insert structure and the small hole does not cause misalignment and cracking of the insert. Strictly supervise and control the small hole T-shaped circular block structure and pore spacing to ensure that the error is controlled at around 0.01mm.

Based on this, in the process of improving the punching structure of precision metal stamping molds, after the drawing design is completed, relevant designers will purchase raw materials centrally and process them according to the design requirements to ensure orderly rough machining. After heat treatment, flat grinding is carried out to ensure the integrity of the entire small hole block structure, and wire cutting technology is used to improve its accuracy. Finally, assembly and use are carried out to ensure the effectiveness of matching and replacement, and to a certain extent, to improve the effectiveness of the entire equipment operation and maintenance. Relevant equipment management personnel should strictly follow standardized operating procedures to complete the design and manufacturing, in order to improve the effectiveness and operational dimensions of the entire operating structure, and ensure the optimization and improvement of the entire small hole insert structure.
