一、进行相对板厚比大的小 直径拉深加工 1.不采用压边圈的条件 当相对板厚比t/D大于2.5％时,则可以不必采用压边圈进行拉深。 t——板厚 (毫米) D——毛坯直径 (毫米) 2.没有压边圈的模口形状 图1表示在不用压边圈进行拉深所用的几种模口形状。
First, the relative thickness ratio of the larger diameter of the small diameter drawing 1. Not using blank holder conditions When the relative thickness ratio t / D is greater than 2.5%, you can not have to use blank holder for drawing. t - plate thickness (mm) D - blank diameter (mm) 2. die without blank holder shape Figure 1 shows the die without blank holder used in several die shape.
