Bolt trimming die manufacturers tell you that the modern automobile industry is developing rapidly, and the process of sheet metal coverings for automobile surfaces is also developing. In the existing process, the processing of sheet metal coverings on automobile surfaces mainly includes blanking, drawing, punching Hole trimming, flanging, shaping and other processes are completed. For the processes of drawing, punching trimming, and flanging, the functions can be integrated into the trimming die and formed by stamping at one time.

Bolt trimming die manufacturers tell you that the trimming die mainly includes an upper die and a lower punch that cooperate with each other. The shape of the concave die and the lower punch is sufficient. The corresponding structure of the trimming die is different according to different processes. Usually in the drawing process, the structure of the trimming die is the simplest, which is used to complete the preliminary forming of the sheet, and then In the second step of the trimming process, the trimming die will increase the trimming function accordingly. For trimming, there will be two corresponding situations. The first edge to be trimmed is laid on the upper punch. Yes, this kind of edge is relatively easy to repair, first press the semi-finished product on the upper punch with the pressing plate, and then the upper punch and the lower punch are closed to complete the mold and cut the edge to be repaired orthogonally, because This type of edge is laid on the lower punch and can be cut orthogonally. The Bolt trimming die manufacturer tells you that the second type of edge to be trimmed is attached to the side wall of the lower punch, and this edge cannot pass through. Orthogonal cutting is carried out, and laser cutting is used for edge trimming in the existing process, which adds an additional process, which needs to be improved.
The Bolt trimming die manufacturer has introduced the production method of the trimming die here, and I hope it will be helpful to you.
