所谓抑制拉深法,即在拉深模压边圈上设置一种对材料起抑制作用的装置,以取代以往的拉深筋,是一种新型的模具结构。下面具体介绍其特性、效果以及与过去加工方法的对比数据。一抑制拉深的特性 (1)能大幅度节省原材料,降低零件成本。尤其目前各厂为了应付原材料价格上涨,正在推行最低限度控制压边废料,提高材料利用率。抑制拉深方法在这方面已获很多实绩,已引起各方面的重视。
The so-called suppression drawing method, which is set in the drawing of the molded edge inhibition of the material on the device to replace the previous drawbead, is a new type of mold structure. The following describes in detail its characteristics, effects and comparison with the past processing methods. A suppression of the characteristics of drawing (1) can significantly reduce raw materials, reduce part costs. In particular, at present, in order to cope with the rising prices of raw materials, various plants are implementing minimum control of edge burrs to increase material utilization. The method of suppressing deep drawing has won many achievements in this respect and has drawn great attention from all quarters.
