Analysis of stamping die status quo advanced level

      Marking the advanced level of stamping die is precision, long life, multi-position progressive die, it has a complex structure, difficult to manufacture large, high precision, long life, high efficiency and low energy consumption characteristics of supplies, is China's key One of precision molds breed development.
Representative of motor core lamination carbide automatic multi-position progressive die, precision of 2 m, step away from the precision of 3 m, 1 double rotary precision, precision pieces 1 m, surface roughness Ra0.1 ~ 0.4 m, life 100 million; US Oberg, Japan Kuroda, France, Czech Republic and other treasure double motor core laminations automatic mode, the accuracy of 1 m, Stepping accuracy 2 m, die life 200 million times. While the accuracy is close to the international advanced level, but life there is a certain gap.
       High levels of air conditioner fin multi-position progressive die, precision of Faces at nearly 2 m, convex, concave die, blanking gap of 0.01mm up to more than 300, a number of fins out of 36 column, die life more than 200 million times; Japan's high-precision machine, the United States OAK, Italy GBS manufactured 36 to 72 the number of fin progressive die, precision of 2 m, Stepping accuracy 3 m, life 500 million times or more . Similarly, the accuracy is close to the international advanced level, but there is a wide gap between the die life.
       CPT reflect the difficult forming electron gun parts (G5) 25 station carbide progressive dies, precision up to 2 m, mold applications in high-speed punch, punching 0.245mm thick non-magnetic stainless steel, after each procedure, Products accuracy of ± 5 m, die life more than 3 million times; Japan's Toshiba, Hitachi and other companies manufactured CPT electron gun parts progressive die, precision is 2 m, Stepping accuracy 3 m, die life over 5 million times . Likewise die life gap.
       High performance integrated circuit frame 32 position progressive die, precision up to 2 m, the speed punch punching speed of 350 to 500 beats / min, life of more than 30 million times; Yamada of Japan, the United States and other manufactured Oberg 100 feet above the framework of the integrated circuit die, accuracy of 2 m, step away from the precision of 3 m, die life 100 million times.

       Also as innovation phone connector 50-position progressive die, precision of 2μm, Stepping accuracy 3μm, die life 200 million times; digital cameras spring plate 18 position progressive die, connector 46-position progressive die, etc. We have reached a higher level.
