Springback occurs when metal stamping parts are formed? You should do this

In the production process of metal stamping parts, plastic deformation in the forming of stamping parts will also occur elastic deformation, and the parts will have certain springback. Springback is the deformation that occurs after the sheet metal is formed and the formed part is taken out of the mold. It will affect the final shape of the part. The amount of springback directly affects the accuracy of the stamping part. So how should this phenomenon of stamping rebound be prevented? Material aspect: On the premise of meeting the product requirements, try to choose materials that are not easy to bend, or increase the thickness of the material appropriately. Secondly, the design of the stamping shape, the stamping parts with complex shapes, in one bending, due to various directions The stress situation is complicated, and several components can be combined to solve the springback problem. The springback problem can also be solved by reducing the value of the R angle of the curved part. When the mold is designed for pre-forming, the one-time forming stamping parts can be distributed in different processes to complete, which can eliminate the internal stress during the forming process to a certain extent, so as to solve the springback defect. By optimizing the blank holder force of the part, adjusting the flow direction of the material, and improving the internal stress distribution of the material, the increased blank holder force can make the part more fully drawn. If the forming is sufficient, the internal and external stress difference will be reduced, thereby causing springback. Decrease. Utilize drawbeads and set the drawing position reasonably, which can effectively change the direction of material flow and effectively distribute the feed resistance on the pressing surface, thereby improving the material forming, and setting the drawing on the parts that are prone to springback The ribs will make the parts more fully formed, the stress distribution will be more uniform, and the springback will be reduced.
