Design Ideas For Punching Structure in Precision Metal Stamping Dies

Design ideas for punching structure in precision metal stamping dies
1. Analysis of punching structure of precision metal stamping dies
Precision metal stamping dies are used frequently in the field of actual equipment applications. The punching insert structure of traditional precision metal stamping dies mainly uses direct processing, or directly punches out corresponding small holes on the template. In the process of improving and optimizing its punching structure, the main thing is to embed its structure on the original template. The reason for deep processing of the punching structure is mainly because the mold production process of the traditional processing structure is more laborious, and the entire mold needs to be disassembled, which will not only waste a lot of manpower and material resources, but also lead to a lot of maintenance costs if problems occur. The use of a new punching structure can improve its overall structural model, and can effectively avoid the problem of blade wear during the punching operation, smoothly upgrade the overall operation and maintenance system, realize mass production and replacement, and improve the overall equipment operation effect.
2. Analysis of the improvement of the punching structure of precision metal stamping dies
After the punching structure of the precision metal stamping die is improved, the original block structure needs to be converted into a two-piece structure, that is, the structure of the punching edge is adjusted to a T-shaped circular structure separately to ensure that the overall equipment application value is higher. After the improvement, the replacement of the equipment only requires the disassembly and installation of the small hole insert structure, which not only saves time, but also makes the replacement of the small hole edge more convenient. In addition, in the application process of the T-shaped circular structure of the punching structure of the precision metal stamping die, the processing operation is also time-saving and labor-saving. It only requires the disassembly and wire cutting of the small hole insert, and the processing time can be reduced to a certain extent. The T-shaped structure of the new structure can be made into a standard part, and can be mass-produced and stored in the spare parts warehouse for emergency use. In short, the T-shaped circular structure of the new structure is more material-saving than the old structure, and the cost is also maximized.
The specific improvement process: ① Combine the traditional structure to design the style of the new small hole insert structure, and effectively optimize the different unit molds according to the actual situation to ensure that the design is made after comprehensive analysis on the original basis. ②During the design process, relevant designers should separate the small hole processing part separately and ensure that the small hole insert structure and sheet material processing parameters meet the actual needs. In particular, the T-shaped round insert of the small hole structure is processed with sheet material, focusing on analyzing the material of the raw materials. Generally speaking, the small hole insert is hard material, the mold is Cr12MoV, and the T-shaped round insert is GBD-2. After the design is completed, the raw materials are purchased centrally to ensure that the rough drilling operation can meet the thread requirements. ③Heat treatment is performed on it, and the hardness is controlled at HＲC58-60. Focus on the flatness of the entire small hole insert after heat treatment, and the size is controlled between 0.02 and 0.03 mm. In addition, the technicians should also pay special attention to the wire cutting processing, strictly control the gap between the insert and the template, and ensure that the T-shaped round insert structure and the small hole gap will not have the problem of insert dislocation and cracking. The small hole T-shaped round insert structure and the distance between the pores are strictly supervised and controlled to ensure that the error is controlled at about 0.01 mm.
It is based on this that in the process of improving the punching structure of precision metal stamping dies, after the design drawings are drawn, the relevant designers will centrally purchase the raw materials and centrally process them according to the design requirements to ensure that the rough processing is carried out in an orderly manner. After heat treatment, it is plane ground to ensure the integrity of the overall small hole insert structure, and the wire cutting operation process is used to improve its accuracy. Finally, it is assembled and used to ensure the effectiveness of supporting use and replacement, and to a certain extent improve the effectiveness of overall equipment operation and maintenance. Relevant equipment management personnel must strictly follow the standardized operation process to complete the design and production to improve the effectiveness and operation dimension of the overall operation structure and ensure the optimization and improvement of the entire small hole insert structure.
