What is a metal stamping part?
We can understand it as the parts formed in the stamping process. The products are widely used in precision connector terminals, relay shrapnel, micro motor shrapnel, IC lead frames, automotive terminals, medical terminals and other consumer electronics industries, or outdoor, furniture and other industries. . What should we pay attention to when processing metal stamping parts? Let’s take a look.
1.Use a single-process mold to punch some simple parts. The complex-shaped parts are punched by multiple punching processes, and the structure or strength of the die is limited, and its inner and outer contours should be punched into several parts. For work pieces with high flatness requirements, a leveling operation can be added after the blanking process.
2. Whether the structure and shape are complex determines the number of processes to be used for the bending part, which is determined according to the number of bending angles, relative positions and bending directions. Why sometimes add a shaping process after bending? This is because the bending radius of the bending part is smaller than the allowable value.
3. When we re-blank the process and then add the trimming process or directly use the precision blanking process, this is because the requirements for the cross-sectional quality and dimensional accuracy of the work piece are relatively high.
4. For the processing of metal stamping parts, the designed stamping parts should be simple in shape and reasonable in structure, which is conducive to the stamping operation, which can not only improve labor productivity, but also facilitate the organization and production of stamping parts processing and mechanization and automation.
5. The properties of the material, the height of the drawing, the number of steps of the drawing, the diameter of the drawing, the thickness of the material and other conditions determine the number of processes of the drawing part, but the drawing process calculation can only be determined. If the fillet radius of the drawn part is relatively small or the dimensional accuracy is required to be high, a shaping process should be added after the drawing.
To improve the stability of the stamping process, we need to increase the number of processes to ensure the quality of 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 area, etc.
