Matters needing attention when processing precision stamping parts

A new member who just joined the company asked the author what is a precision stamping part? The author summed up some knowledge about precision stamping parts: we can understand it as parts with constant thickness during processing. In fact, they are thin metal parts. Stamping, bending, stretching and other operations can be processed. What should be paid attention to when processing precision stamping parts? Let's take a look together. 1. Use single-process molds to punch some simple parts. Use multiple stamping processes to punch parts with complex shapes, and the mold structure or strength is restricted, and its inner and outer contours should be punched out in several parts. For workpieces with high flatness requirements, a leveling operation can be added after the punching operation. 2. Whether the structure shape is complex or not determines the number of processes required for the bending part, which is determined by the number of bending angles, relative positions and bending directions. Then why do we need to add a shaping process after bending? This is because the bending radius of the bending piece is smaller than the allowable value. 3. When we add a trimming process or directly adopt a precision blanking process after the blanking process, this is because the requirements for the quality of the section and the dimensional accuracy of the workpiece are relatively high. 4. For the processing of precision stamping parts, our goal is to use the least and simplest stamping parts to process. The designed stamping parts should be simple in shape and reasonable in structure. This is conducive to the stamping operation, not only can improve labor productivity, but also is conducive to stamping Organized production and mechanized and automated production of parts processing. 5. We must determine the number of processes based on the company's existing mold making capabilities and the status of stamping equipment. In addition, the mold making ability must ensure that the mold processing and assembly accuracy meet the standard, otherwise it can only increase the number of processes. Sixth, the nature of the material, the drawing height, the number of drawing steps, the drawing diameter, the material thickness and other conditions determine the number of drawing processes, but it must be determined by drawing process calculations. If the fillet radius of the drawn part is relatively small or the dimensional accuracy is high, it is necessary to add another shaping process after the drawing. Seven, if we want to improve the stability of the precision stamping process, we need to increase the number of processes to ensure the quality of the stamping parts. For example, the additional positioning process hole punching of the bending part, the deformation reduction hole punching in the forming process to transfer the deformation zone, etc. Well, the above 7 points are the points that must be paid attention to when processing precision stamping parts. It is worth discussing and learning together. [Related recommendation] Learn more: How much do you know about new energy automobile stamping parts?
