Some factors affecting the processability of metal stamping parts and the process requirements of metal stamping parts

The so-called craftsmanship of metal stamping parts is the difficulty of processing this metal stamping part. Perfect stamping technology should ensure high raw material usage, fewer processing procedures, simple structure of stamping die and long service life, high quality of stamping parts, and simple and convenient operation of stamping workers. There are many factors that affect the manufacturability of metal stamping parts, such as the product shape, size, accuracy and performance of metal stamping parts. The following motion is for the stamping author to analyze some factors affecting the processability of metal stamping parts and put forward the process requirements of metal stamping parts. First, the shape of the metal stamping parts should be simple and symmetrical, preferably composed of arcs and straight lines, so that less waste can be generated when designing the layout. Second, try to avoid long cantilevers or slots on metal stamping parts, and the minimum width should be greater than twice the material thickness. The distance between the hole and the hole, the hole and the edge of the metal stamping parts should not be too small. Third, the size of the punching hole should not be too small, so as not to break the punching needle during the stamping process. Fourth, under normal circumstances, the shape of metal stamping parts should not have sharp corners, but round corners should be used for transition, which is conducive to the processing of stamping dies and improves the service life of the dies. Fifth, when punching on the punching and bending parts and the punching and drawing parts, the distance between the edge of the hole and the straight wall of the workpiece cannot be too small. If the distance is too small, the hole will be deformed after punching and forming. After punching, the punching needle will easily break. 6. The position of the minimum incision and the width of the minimum incision are shown in the figure below: Seven, the limit size of the side incision is related to the length of the incision and the thickness of the material. You can refer to the figure below: 8. The limit size and curvature of the side cut curved incision The relationship between radius and material thickness is shown in the figure: Previous: Common problems and solutions in most small metal stamping factories
