1 概述 多工位级进模在二十世纪四十年代已经出现,到六十年代有了很大的发展。发展的背景主要是由于: (1)电子技术的发展与发达,特别是集成电路的出现,使产品趋向于小型化。其零件多由薄的金属板材构成,在大量生产中,适宜采用多工位级进模。 (2)精密加工机床的发展,如座标磨床,精密线切割机床等,赋与多工位级进模
1 Overview The multi-position progressive die was introduced in the 1940s and has been greatly developed in the 1960s. The development of the background is mainly due to: (1) the development and development of electronic technology, especially the emergence of integrated circuits, the product tends to be miniaturized. Its parts are mostly composed of thin metal sheet, in mass production, suitable for multi-position progressive die. (2) the development of precision machining machine tools, such as coordinate grinding machine, precision wire-cutting machine tools, etc., and multi-station progressive die
