以冲孔来代替钻孔加工,可以节省大量的工时,降低成本,提高工作效率。现向大家介绍一副以对向冲裁半盲孔来代替钻孔加工的模具。 一、模具结构 对于图1所示零件中的三个螺纹孔的加工方法,过去采用先钻孔而后攻丝。后曾采用二付模具冲孔来取代钻孔的方法,现采用了对向冲裁半盲孔的方法,使该零件的三个孔由一副模具冲制出来,从而大大地提高了工效,降低了成本。 模具的结构见图2,零件的总体尺寸是 To punching instead of drilling, you can save a lot of working hours, reduce costs, improve work efficiency. Now to introduce a pair of semi-blind punching to replace the drilling mold. First, the mold structure For the three parts shown in Figure 1, the three tapped holes in the process, the first use of the hole before tapping. After using two pairs of mold punching to replace the drilling method is used to punching semi-blind hole method so that the three parts of the hole punched out by a pair of molds, thereby greatly improving the work efficiency, Reduce costs. The structure of the mold shown in Figure 2, the overall size of the parts is
