How to promote the application of precision stamping technology

Precision stamping is a high technology in the stamping field. In all kinds of electromechanical and home appliance manufacturing enterprises, if their products reach a moderate economic production scale for mass production, reasonable application of fine blanking technology can obtain good technical economy and occupational safety. benefit. The promotion and application of precision stamping technology requires a good solution to the following problems: 　　 (1) Update the concept, put people first, and use fine blanking to replace more noise in the cutting process and stamping production and the occasional pressure on the hands and broken fingers. Injury accidents are two horrible problems, and there is no effective way to reduce them so far. 'People-oriented, adhere to sustainable developmentMost of the noise during stamping exceeds 95dB(A), which is harmful to the health of workers. Fine-blanking machines are mostly fully hydraulically driven. There are airtight protective screens outside the mold working area, fully automatic operation, low labor intensity, and noise generally does not exceed the standard specified 85dB(A). It can ensure safe production, and the work site has low noise pollution. The scientific development concept of 'people-oriented, sustainable development'. Moreover, the fine blanking process produces medium and thick plates with t>3mm, and parts with complex shapes. Cutting and other processing methods are difficult to implement mass production. It is the advantage of fine blanking high technology that should be actively promoted and applied. More Instead of cutting, it achieves high-quality, high-yield and low-consumption. (2) Carry out cooperation and mutual benefit to overcome the traditional concept of 'big and complete, small and complete' left over from the planned economy era, and to carry out large-scale cooperation to eliminate parts that require fine blanking but cannot be fine blanked. Committee cooperation. Carrying out fine-blanking processing on its own requires a complete set of relevant technologies and huge capital investment to purchase expensive fine-blanking equipment; it requires a group of technical personnel with different professions to support, long cycle, large investment, and cooperation with external commissions is the best policy. But for factories that have reached economic production scale and require a large variety and large quantity of fine blanking parts, such as automobiles, motorcycles, sewing machines, cameras, switch appliances, instruments, home appliance hardware, etc., establish their own fine blanking production workshops (Point) As long as the equipment load rate is sufficient, the benefits will be very good.　　(3) The supporting technology should keep up, and the related process should be perfect. The promotion of fine blanking technology involves many supporting technology categories and types of work, as well as directly related and applied process technology. It is a huge and complex system engineering.　　The technologies directly supporting the implementation of fine blanking process mainly include: fine blanking raw material pretreatment technology, physical and chemical measurement technology, lubrication technology, fine blanking die design and manufacturing and repair technology, CNC fine blanking machine operation and maintenance technology, etc. These supporting technical categories have professional process technology fields and complete sets of equipment, and there must be specialized technicians and technicians to perform operations to coordinate the work required for fine blanking.　　The metallurgical technology directly related to the promotion of fine blanking technology is related to the refining of fine blanking die steel and the development and finishing tasks of special steel grades for fine blanking. In addition, the forging of the forging blanks of the working parts of the fine blanking die is a difficult and demanding free forging process technology, and all need to adapt to the technical requirements of fine blanking and gradually improve. (4) The design, manufacture and repair of fine stamping dies take a professional path. Compared with ordinary all-steel dies, the manufacturing technology requirements of fine stamping dies are higher and more difficult. There are many types of high, precise and sophisticated equipment required for mold making. The process is also complicated. It is more economical to manufacture fine stamping dies by a certain basic stamping die manufacturing professional factory, and it is recommended and recommended to take the road of specialized production.　　(5) Cultivation of professional and technical personnel 　　Fine blanking technology is a high-tech and development direction in the stamping field. The state, related enterprises, institutions, and related technical categories and scientific research institutions should focus on cultivating professional talents and cultivating relevant professionals with the intention of fine-tuning expertise and skills. Training specialized technical personnel from practice, such as selecting and cultivating specialized personnel who promote fine-blanking technology from technical personnel in stamping process and die design and manufacturing, will quickly get started and achieve results.
