what are precision stamping parts?

We can understand that in the process of processing parts of the same thickness, in fact, sheet metal hardware, stamping, bending, stretching and other operations can be processed, we pay attention to what things in the process of precision stamping parts?

1. Use a single mold to cut some simple parts. The use of multiple stamping processes to cut complex parts, and the mold structure or strength is limited, its internal and external profiles should be divided into multiple parts. For parts with higher flatness, leveling operations can be added after the blanking process as needed.

2. Whether the complexity of the structure shape determines the number of processes used to bend the part depends on the number of bending angles, relative positions and bending directions. So why is a plastic process sometimes added after bending? The bending radius of the bending part is less than the allowable value.

3. When we increase the finishing process or directly use the precision blanking process after the blanking process, it is because there are high requirements for the cross-section quality and dimensional accuracy of the workpiece.

4, for the processing of metal stamping parts, our goal is to use simple stamping parts processing, so that the design of precision stamping parts is simple in shape and reasonable in structure, which is conducive to the operation of stamping, not only can improve labor productivity, but also is conducive to the production of stamping parts processing mechanisms and mechanization and automation.

5. We should determine the number of procedures according to the existing capacity and stamping equipment of the enterprise. The ability of the mold needs to ensure that the processing and assembly accuracy of the mold meets the standard, otherwise the number of procedures can only be increased.

6. The properties of the material, drawing height, drawing steps, drawing diameter, drawing thickness and other conditions determine the number of drawing parts. However, the amount can only be determined by the calculation of the drawing technology, if the drawing part of the radius is small or the dimensional accuracy is high, the plastic process needs to be added after the drawing.

In order to improve the stability of the precision stamping process, we need to increase the number of procedures to ensure the quality of the stamped parts. For example, a positioning punching system is added for positioning bent parts, and deformation is increased during forming to reduce the deformation zone transferred by punching.
