Analysis on the processing technology of stamping parts

  Compared with the casting and forging, the stamping parts of Dalian have the characteristics of thin, uniform, light and strong. Stamping can be produced from other methods is difficult to manufacture with ribs, rib rolling or burring of the workpiece, to enhance its rigidity. Due to the adoption of precision molds, the accuracy of the workpiece can reach micron level, and high precision, uniform size, can be punched out of the hole, the boss, etc.. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, the general production of hundreds of pieces per minute. Metal stamping industry in addition to its regional industrial clusters, the development in other areas, we can see that the current development of first-tier cities is fairly mature, no matter what the market will have the appropriate scale of operation. But relatively speaking, the two or three line of the city's development as well as the lack of. In the next three to five years, with the deepening of urban planning, I believe it will lead to the development of the two or three level of the city's hardware channel.

  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. Although the domestic stamping die for automobile stamping parts have a vision, but the domestic stamping parts of the development of the imbalance phenomenon is also worth looking at. Although China's auto production is amazing, but many of them are also from foreign well-known automobile brand capital investment and mass production. Stamping production technology and equipment is developing unceasingly, in addition to the traditional use of the press and steel die stamping parts manufacturing, hydroforming and spinning forming, superplastic forming, explosive forming, electric water formingelectromagnetic forming a variety of special stampingtechnology is also developing rapidly, the technology level of stamping has been raised to a new the height of the.
