一、通用模架我厂冲压件品种多、批量小、精度高，生产周期短。为此，设计了冲孔落料成形通用模架，通过配制不同的模芯便可冲制不同的工件。通用模架见图1。图1图中件l～10为通用模架，件11～18为专用模芯，件7上模板、件10下模板、件9导柱、件8导套、件6定位村套、件4及5定位 First, the common mold I stamping plant varieties, small batch, high precision, short production cycle. To this end, the design of punching blanking forming a common mold base, through the preparation of different mold core can be punched into different parts. Common mold frame shown in Figure 1. Figure 1 Figure l ~ 10 for the universal mold base, 11 to 18 for the special mold core, the template on the 7 pieces, 10 pieces under the template, pieces 9 guide posts, pieces 8 guide sleeve, And 5 positioning
