What are the processing techniques of CNC stamping?

It is inevitable to encounter some problems in sheet metal processing, but some problems can be solved by some common knowledge of sheet metal processing. For example, what are the processing techniques of CNC stamping?

1. The processing technology of cutting materials first and processing later. When blanking, you first need to cut the plate, use a shearing machine to cut the plate according to the external dimensions of the part, and then edit the CNC program to enter the processing stage. When processing sheet metal parts, the clamps hold the plate firmly before processing the parts. Pay attention to trimming the plate when blanking, and the four edges must have good verticality.

2. Stamping and nesting processing technology. Lay out the material directly on the entire plate, arrange the 18 parts neatly, and use the rectangular mold of the punch machine to cut each part separately. However, mainly to prevent the parts from falling off, micro-connections must be reserved to make the plate Maintain a holistic state. After one clamping is completed, there is a rectangular mold between the parts. The size of the mold must be fully considered, that is, the gap between the parts is 5mm, and the material utilization rate is below 94%. This processing technology requires the use of 7 types of molds, and one more set of rectangular molds is used than the first process. During the process of connecting and cutting parts, the rectangular mold is stamped 360 times, so that it takes 2034 stamping times to complete one piece, and the whole process takes 12 minutes. This kind of processing method has relatively low precision of parts. During the roundabout processing, it is easy to cause the coil material to malfunction between the upper and lower turntables of the machine tool. There are potential safety hazards in the processing. Therefore, it is best to use the cutting method to cut the parts. performed in a vulgar state. In addition, because there are micro-joints in the parts, the joints need to be burred and polished after the processing is completed.

The above is the analysis of sheet metal processing CNC stamping process. It is for reference only. I hope it will be useful to everyone.
