Electronic product stamping manufacturers share: blanking and layout design knowledge, learn about it

The designer of the electronic product stamping manufacturer tells the author that if you want to reduce the cost of stamping parts, the design and layout of the product is a very important step. Reasonable stamping and layout can effectively save materials and save costs. Today The author takes you to understand the knowledge of blanking layout design: 1. Reasonable use of materials: The waste generated by blanking can be divided into structural waste and process waste. According to the reasonable utilization of materials, the layout can be divided into three categories: Yes Scrap nesting, low-waste nesting and no-waste nesting; Second, nesting edge: the process waste left in the blanking room and the side of the strip during nesting is called edge overlapping, and its function is to compensate for positioning errors And the shearing error ensures that qualified parts can be punched out. In addition, it can increase the rigidity of the strip, facilitate the feeding of the strip, and can avoid the burr on the edge during stamping and strain the mold; Third, the layout designed by the electronic product stamping manufacturer Figure: Strip length L, sheet thickness T, step distance S, and side laps A between the workpieces, the position where the cross-section line is used to punch, manual feeding, and the side pressure device can have a smaller lap value. Material The thicker it is, the greater the edge value. The above article comes from 18 years of metal stamping parts processing and automobile stamping parts customization.
