To observe the challenges and opportunities of stamping parts in Dalian

    Stamping parts warping mainly due to the process of stamping process, there is a gap between the force and the reaction force is not a line of torque. Such as the die gap is too large and concave edge with reverse taper, or ejector and the workpiece contact area is too small to produce warpage, are prone to punching warpage. The industry is an important industry stamping processing industry is the basic industry of metal forming machinery manufacturing industry, its development level reflects the manufacturing technology of a country's competitiveness, the products involved in the aerospace industry, automobile manufacturing, electronic appliances, instrumentation industry, equipment manufacturing and other aspects, the scope of application is very widely. Among them, the automobile manufacturing industry is the largest industry demand for stamping parts, stamping parts of car number accounted for more than 75% of the total number of parts; in the automobile industry is developed in Japan, its sales accounted for total sales of automobile stamping parts stamping industry 68%. Wrinkling in the stamping process can cause the parts to be scrapped, which not only improves the manufacturing cost, but also causes the waste of raw materials, needs analysis and control.

    At present, the stamping die industry Chinese obvious characteristics, its development mainly shows: continuously more large sophisticatedcomplex and rapid economic development of products, technology will continue to improve, continue to shorten the manufacturing cycle, die stamping production will continue toward informationization, digitization, fine, high-speed and automation. The development, characteristics of enterprises will further enhance the comprehensive strength and core competitiveness of the various aspects of the. Because of obvious progress and the rapid development of the domestic stamping die technology, coupled with the domestic stamping die low prices, in recent years, some domestic joint venture brand car has many stamping parts imported from the past to be purchased in china. At the same time, with the development of the international competitiveness of China's auto stamping parts industry, some foreign brands have begun to increasingly purchase stamping parts from China.
