Metal stamping parts forming bending hole when change the location of the problem how to solve?
Speaking of metal stamping parts we are not unfamiliar, mostly used for production class living supplies, forming forming more and with a hole for some products, we must seriously rise, because some stamping parts with a round hole and closer from the forming parts will be prone to hole deformation, and that we can study the reasons and countermeasures: metal stamping hole position size is not accurate, usually forming bending tension and thinning, hole different heart, usually forming highly enough, blank slip, resilience, and so on and so forth, forming more close to the hole more prone to deformation;
Position of metal stamping parts hole size is not correct, you need to strictly control the forming radius, Angle and the thickness of the material, to ensure both side stamping forming highly consistent, if because of wear and tear caused by mould does not reach the designated position requires correct positioning pin and positioning plate, in the design of forming die to ensure that when from forming parts to the side of hole spacing greater than a certain thickness of sheet metal, or design a auxiliary hole forming deformation to absorb the stress, can prevent the deformation of adjacent holes, we can also adopt multi-channel processes, such as for punching forming again can first;
