What should be paid attention to in the processing of stepped deep drawing parts?

Today, let’s talk about stepped deep drawing parts. The processing technology of the stamping parts is basically the same as the drawing of cylindrical stamping parts. That is to say, each step is equivalent to the drawing of the corresponding cylindrical stamping part; how to judge whether it can be done once What about deep drawing? We can judge according to the ratio of the height h of the part to the minimum diameter dn; look at the picture in the stamping part processing, the method of drawing a stepped part multiple times includes the following points: 1. When the ratio of the diameter of any two adjacent steps (Dn / dn-1) is not less than the limit drawing coefficient of the corresponding cylindrical stamping parts; drawing method is shown in figure a; 2. If the ratio of two adjacent step diameters (dn / dn-1) is less than Corresponding to the ultimate drawing coefficient of cylindrical stamping parts; drawing method as shown in figure b; article recommendation: what points should be paid attention to when stamping parts processing plants try out the mold?
