Process dry goods: how to punch the process cuts of deep-drawn metal parts

In the previous article, we learned about the role of the deep-drawing ribs of metal deep-drawn parts. Today, the author will discuss with you the role of process cuts in metal deep-drawn parts and how to punch the process cuts; When some deep protrusions are punched out, the material cannot be supplemented from the outside of the blank, which leads to the partial cracking of the workpiece. At this time, it can be considered to punch out the process cut or process hole at the appropriate position of the local protrusion deformation zone to make the fracture area Material compensation can be obtained from the inside; and the process cut can be processed in two ways: 1. Punching out during blanking is used for workpieces with a shallow local forming depth; 2. Deep drawing metal parts are in the process of drawing This is a relatively common way to cut out. The plasticity of the material can be used to obtain a larger forming depth. When the process hole is cut in the process, it is often a tearing process method. The material is not completely separated, and the scrap of the cut can be The trimming process is also removed, because this type of waste is more difficult to remove from the stamping method at one time, so it is necessary to increase the subsequent process to achieve it.
