“机械工人”(热加工)58年5期发表了“冲床多下料和自动滾料装置”及“在曲軸冲床上切料用的工具”两篇文章,其中介紹的工具是比較好的。但这两个工具也还有一些缺点。譬如,下料定位調整比較麻煩;刀刃間隙調整困难;没有拖板装置等。現在把我厂在生产中所用的冲床切料模具,介紹給大家参考。模具的結构如图1所示。軸1下端有螺紋与上盖板2固定在一起,用内六角螺釘38把上刀架27固定在盖板2上。上切刀5和下切刀17是通过楔鉄25、18以及 In the 58th issue of “Machinists” (Hot Processing), two articles, “Punch Multi-blanking and Automatic Roll-off Devices” and “Cutting Tools for Crankshaft Punch,” were published in the last five years. The tools presented are better. However, these two tools also have some disadvantages. For example, cut the positioning adjustment is too much trouble; blade clearance adjustment difficult; no drag device. Now I used in the production plant in the press cutting die, introduced for your reference. Die structure shown in Figure 1. The lower end of the shaft 1 is screwed together with the upper cover 2, and the upper knife holder 27 is fixed on the cover 2 by using the hexagonal screw 38. Upper cutter 5 and lower cutter 17 are passed through wedges 25, 18 and
