For the stamping process die, we are no stranger, stamping die said simple and simple, said complex and complex. Today, let's talk about what kind of problems will arise in the production of stamping die.
1、 Planning skills and core theories
The planning and manufacturing skills and innovation of precision stamping die are not enough, and the key planning content and skills, production process, theory and core skills in many advanced dies are not mastered enough, which leads to the difficulty in improving the overall level of the die and mold. It has been in the stage of technical follow-up and tracking, and there is a lack of solid support for relevant planning and production skills to reach or surpass the international advanced level.
2、 Service life of mould
Due to the influence of die materials, heat treatment, manufacturing and installation skills and other related elements, the service life of stamping dies in China is basically lower than the international advanced level, and the gap is more than 30%. In particular, the increase of mold repair times reduces the production efficiency, disrupts the production rhythm, increases the mold maintenance cost, thus affecting the overall market competitiveness of the mold.
3、 Die trial and safety and reliability
Die trial is a process of theoretical experiment, comment and inspection on the die after the completion of die design and production; it is the actual display of mold design and production problems, and also the comprehensive reflection of stamping die design, production skills and professional technical level. The reliability and stability of the mold is the evaluation benchmark of the mold design and production quality and the guarantee of the normal use of the mold. Due to the lack of in-depth exploration of the invisible common sense and skill accumulation in the design and production process of multi-position and multi-function stamping die in China, compared with the world's advanced die and mold enterprises, the time for trial mold, adjustment and repair of multi-functional and multi-functional stamping die in China is increased by more than 30%. Compared with the cutting-edge technology of mould without trial procedure in foreign countries, the distance between mould testing skill and reliability and stability of mould in China can not be concealed.
4、 Mold foundation and core technology
Mold design is a professional skill with strong practicality. For a long time, China has paid great attention to the practice of mold design and production. However, due to the lack of deep research on the basic theory and skills of stamping die, the development of basic theory and skills of die design and production is slow. In addition, the specialized division of labor of stamping die enterprises can not be refined, small and complete mold enterprises still occupy a dominant position, the core competitiveness of enterprises is difficult to form, and the enterprise's own skills and innovation ability lag behind foreign advanced mold enterprises. In terms of die materials, standard parts and other related die matching, there is a backward technology, which directly affects the overall skill level of China's multi position and multi-functional stamping die. Therefore, there are still many weak links in the basic skills support of multi position and multi-function stamping die.
5、 New mould technology
With the continuous emergence of new technology and new products, foreign stamping dies have been developed from conventional single pair progressive die to multi-functional combined die, production line matching combined die tooling, super large progressive die and micro parts stamping forming die. However, most of Chinese enterprises still focus on the former single pair progressive die serialization and industrialization, and have not grasped the special high-precision Die such as super large high-precision, ultra-high-speed stamping, ultra-thin, super strong and micro parts of the core technology of stamping, multi-functional composite die is still not much contact. Therefore, our country still needs to continue to carry out the core technology research of new mold, broaden its application field, and lay a good foundation for catching up with and surpassing the international advanced level.
