What are the precautions for processing precision stamping parts?
What are precision stamping parts? We can understand that in the process of processing parts of the same thickness, it is actually sheet metal hardware that can process stamping, bending, stretching and other operations. What do we pay attention to in the process of precision stamping parts? Follow the precise author to take a look. 1. Use a single die to punch out some simple parts. Use multiple stamping processes to punch complex parts, and the mold structure or strength is limited, the inner and outer contours should be divided into multiple parts for punching. For workpieces with higher flatness, as required, leveling operations can be added after the blanking process. 2. Whether the complexity of the structure shape determines the number of processes used to bend parts, which depends on the number of bending angles, relative positions and bending directions. So why sometimes add a plastic process after bending? The bending radius of the bent part is smaller than the allowable value. 3. When we increase the precision machining process or directly adopt the precision blanking process after the blanking process, it is because of the high requirements for the quality of the section and the dimensional accuracy of the workpiece. 4. For the processing of metal stamping parts, our goal is to use simple stamping parts to make the design of the stamping parts simple in shape and reasonable in structure, which is conducive to the stamping operation, not only can improve labor productivity, but also help stamping parts Production of processing institutions and mechanized and automated production. 5. We have to determine the number of procedures based on the company's existing capabilities and stamping equipment. The ability of the mold needs to ensure that the processing and assembly accuracy of the mold meet the standard, otherwise the number of procedures can only be increased. 6. Material properties, drawing height, number of drawing steps, drawing diameter, drawing thickness and other conditions determine the number of drawing parts. However, the quantity can only be determined by the calculation of the drawing technology. If the radius of the drawn part is small or the dimensional accuracy is high, a plastic process needs to be added after the drawing. 7. In order to improve the stability of the stamping process, we need to increase the number of procedures to ensure the quality of stamping parts. For example, positioning and punching systems are added for positioning and bending parts, and deformation is increased during the forming process to reduce the punching transfer deformation zone.
