How to control the deformation of Hardware Stamping Parts during the stamping process? | |
1. Reasonable design of molds Mold design is crucial to controlling the deformation of Hardware Stamping Parts. First, ensure that the gap of the mold is appropriate. If the gap is too large, the material is prone to tensile deformation during the stamping process; if the gap is too small, the material will be deformed by excessive extrusion force. For example, when punching thin plate hardware, a suitable gap can ensure the quality of the punching section and reduce deformation caused by undesirable conditions such as tearing. At the same time, the edge shape of the mold also needs to be carefully designed. The use of a reasonable edge angle can make the material receive a more uniform force during the punching process, thereby reducing deformation. 2. Optimize stamping process parameters The selection of stamping process parameters directly affects the deformation of Hardware Stamping Parts. Among them, the stamping speed is a key factor. Appropriately reducing the stamping speed can reduce the impact force on the material in an instant, thereby reducing the amount of deformation. For example, in some complex Hardware Stamping Parts processing with high requirements for shape accuracy, slowing down the stamping speed can effectively control deformation. In addition, the control of the blanking force is also very important. Reasonable blanking force can prevent the material from wrinkling and deforming during the stamping process. For stretching Hardware Stamping Parts, the material can be stretched evenly by adjusting the blanking force to avoid excessive local deformation. 3. Choose the right material The performance of the material has a great influence on the deformation of Hardware Stamping Parts. Selecting materials with good plasticity can better control the deformation. For example, under the same stamping conditions, aluminum alloy materials are easier to stamp than some high-carbon steel materials, and the deformation is relatively small. Moreover, the uniformity of the material thickness cannot be ignored. If the material thickness is uneven, it will cause large deformation during stamping due to different forces in different places. Therefore, when purchasing materials, the consistency of material thickness must be strictly checked. 4. Use appropriate auxiliary tooling Appropriate auxiliary tooling can help control the deformation of Hardware Stamping Parts. For example, the use of positioning devices can ensure the accurate position of the material in the mold, make the force uniform during the stamping process, and reduce deformation caused by position deviation. Elastic unloading devices can also be used to avoid additional deformation forces on stamping parts during unloading. Especially for some thin-walled Hardware Stamping Parts, these auxiliary tooling can play a good protective role and effectively control the deformation. | |
