今年二月,我站模具队和国营七○六厂共同研制成功了自动叠装级进模具。使U型铁芯片在冲压过程中实现了自动叠装,从而提高了U型铁芯产品的质量,缩短了生产周期,提高了经济效益。这种自动叠装级进模具在国内模具制造业中还是个首创,它为叠装技术在国内开花结果奠定了良好的基础。铁芯自动叠装技术,是国际上80年代发展起来的新技术,是利用一付高精度的级进模具直接从模具落料洞口中,将冲片按一定的先后次序,同一毛刺方向,一定的叠厚叠装 In February this year, I station die team and the state-owned 706 plant jointly developed a success of automatic cascading progressive die. So that the U-shaped iron sheet in the stamping process to achieve automatic stacking, thereby enhancing the U-core product quality, shorten the production cycle and improve economic efficiency. This automatic stacking progressive die in the domestic mold manufacturing industry is still a pioneer, it is stacked technology in the country flowering results laid a good foundation. Iron core automatic stacking technology is the international development of the 80’s new technology is the use of a pair of high-precision progressive die directly from the mold blanking hole, the punching film according to a certain order, the same burr direction, a certain Stacked stack
