Large head

The importance of the dimensional accuracy of the head is not high. There are fillet transition at the junction of the face and the face. It can be seen that the head can be formed by drawing, flanging, etc. at one time, without trimming the interior. Through the above process analysis, combined with the traditional process arrangement and the die structure used, a new process procedure is adopted: blanking, drawing, punching and flanging, and a four process composite die is used for one-time stamping.
