Six major 'precision' stamping die designs in my country to overcome 'problems

Common precision stamping die design and manufacturing problems are as follows: 1. Mold design and manufacturing precision stamping die planning and production skills cannot be innovative, and the key planning content and skills in many advanced molds and the skills, theories and core skills in the production process cannot be mastered. Therefore, it is difficult to improve the overall level of molds. It has been in the stage of skill follow-up and pursuit. It is still lacking the support of relevant planning and solid skills to reach or even exceed the international advanced level. 2. Mold service life Due to the influence of mold materials, heat treatment, production and installation skills and other related factors, the use time of stamping dies in China is basically lower than the international advanced level, and the distance is more than 30%. In particular, the number of mold repairs has led to an increase in the number of mold repairs, reduced the production rate of precision metal stamping parts, and increased the cost of mold repairs, thereby affecting the overall competitiveness of my country's mold market. 3. Mold Trial and Safety and Reliability Trial is a process of theoretical experiment, comment and inspection of the mold after the design and production of the fine stamping die is completed. It is the actual display of the mold design and production problems, as well as the stamping die design and production skills. And a comprehensive reflection of the technical level of professionals. The reliability and stability of the mold are the benchmark for the quality of mold design and production and the guarantee for the normal use of the mold. Because our country lacks the in-depth exploration of the invisible knowledge and skill accumulation in the design and production process of multi-station and multi-function stamping dies, compared with the world’s advanced mold companies, our country’s multi-station and multi-function stamping dies test molds, Adjustments and repairs during mold use have increased by more than 30%. Compared with foreign countries that are currently studying the cutting-edge technology of molds without trial procedures, the distance between the mold trial skills and the reliability and stability of the mold in my country cannot be concealed. 4. Die foundation and core technology Fine blanking die design is a highly practical professional skill. For a long time, my country has paid great attention to the practicality of die design and production, but due to insufficient research on the basic theory and skills of stamping dies, As a result, the development of basic theories and skills of mold design and production is slow. In addition, the specialization of stamping die companies cannot be refined. Small but lacking, large and complete die companies are still dominant. The central competitiveness of the company is difficult to form. The company's own skills and innovation can lag behind the advanced foreign countries. Mould enterprise. In terms of mold materials, standard parts and other mold-related matching, there is a lack of skills, which directly affects the overall skill level of China's multi-station and multi-function stamping dies. Therefore, there are still many weak links in the basic technical support of multi-station and multi-function stamping dies. 5. New mold technology. With the continuous emergence of new processes and new products, foreign stamping dies have now changed from the conventional single-pair progressive die to multi-functional combined molds, production line supporting combined mold tooling, extra large progressive dies, and stamping forming of fine parts. Molds and other directions, while most Chinese enterprises still focus on the serialization and industrialization of single-pair progressive dies in the past, and have not yet grasped the special high-precision molds such as large-scale high-precision, ultra-high-speed stamping, ultra-thin, The core technology of forming stamping dies for super and fine parts has little contact with multi-functional composite dies. Therefore, our country also needs to continue to develop the core technology research of new molds, broaden its application fields, and lay a solid foundation for catching up with the international advanced level. 6. Commonly used facilities for mold supporting and parts. Commonly used parts and supporting parts of multi-station and multi-functional stamping molds are the basic conditions for the rapid development of the mold as a whole. However, due to the heat treatment, materials, standard parts and other common mold parts and supporting parts in my country The level of skills and quality is low, and the basic parts and accessories of advanced molds mainly rely on imports. Therefore, my country urgently needs to improve the skills and quality level of common parts and accessories of molds.
