Problems in the design and manufacture of precision stamping dies

Precision stamping parts are produced by stamping dies. The importance of stamping dies in stamping parts manufacturers can be imagined. The mold teacher often encounters some problems when designing and manufacturing precision stamping molds. Only by solving these problems can a good mold and a good product be produced. This also reflects the mold technology level and market competition of an enterprise. force. Common problems in the design and manufacture of precision stamping die are as follows: 1. Die design and manufacturing precision stamping die planning and production skills cannot be innovative, key planning content and skills, and skills, theories and core skills in the production process cannot be mastered, leading to It is difficult to improve the overall level of molds and lack the support of relevant planning and production skills. 2. Mold test and safety/full reliability test is a process of theoretical experiment, comment and inspection of the mold after the design and production of the fine punching die is completed. Comprehensive reflection of production skills and technical level of professional personnel. 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. 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-functional stamping dies. 3. 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 is basically lower than the national level. 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. 4. Mold foundation and core technology Fine blanking mold design is a very practical skill. For a long time, my country has paid great attention to the practicality of mold design and production. However, due to insufficient research on the basic theory and skills of stamping dies, The basic theory and skills of mold design and production are developing slowly. In addition, the specialization and division of labor of stamping die companies cannot be refined, and companies have their own skills and innovation to lag behind. 5. Commonly used facilities for mold matching and common parts and accessories for multi-station and multi-functional stamping dies are the basic conditions for the rapid development of the mold as a whole. Our country mainly depends on imports. It is necessary to improve the skills and skills of common mold parts and accessories. Quality level. 6. New mold technology. With the continuous emergence of new processes and new products, foreign stamping dies have now changed from the conventional single progressive die to the multifunctional combined die, the production line supporting combined die tooling, the extra large progressive die and the stamping forming of fine parts. Moulds and other directions are being developed, and most Chinese enterprises still focus on the serialization and industrialization of single-pair progressive dies in the past, and they need to continue to carry out research on the core technology of new molds to broaden their application areas.
