一、模具结构 86年初,我厂承接图1零件的加工任务,该零件要求表面无折皱、无划痕、光滑无毛刺、不变色等。但加工工艺上碰到了很大问题。0.01mm厚、宽0.35±0.05mm、长150mm的金属箔条,无论用机加工、线切割、冲裁都难以加工出来。为此,设计如图2所示的手动冲剪模,冲剪出的零件满足了设计要求。 First, the mold structure 86 early, I plant to undertake the processing tasks of Figure 1 parts, the parts require no wrinkles on the surface, no scratches, smooth burr, no discoloration. But the processing technology has encountered a big problem. 0.01mm thick, 0.35 ± 0.05mm wide, 150mm long metal foil, whether machining, wire cutting, punching are difficult to process. To this end, the design shown in Figure 2 manual punching die, punching out the parts to meet the design requirements.
