What should be paid attention to when machining precision stamping parts?

Precision stamping parts are manufactured through multiple stamping processes, and its manufacturing is relatively difficult. In order to improve the pass rate of product processing and meet the needs of users, when we process this part, there are many things to pay attention to. Specific needs Pay attention to which ones? Let's take a look together.

1. Simple parts are completed by single-process molds, and complex parts are completed by multiple stamping processes. When machining, if the mold structure or strength is limited, then when machining the inner and outer contours of the part, it should be divided into multiple parts for punching.

2. If the part needs to be bent, the number of processes should be determined according to the complexity of the shape and structure during processing, and the number of bending angles, bending direction and relative position should also be considered.

3. If there are higher requirements for the dimensional accuracy and section quality of the parts, then after the blanking process is completed, an additional trimming process is required.

4. When the parts are deep-drawn, the use of the deep-drawing process requires precise calculation. When calculating, it is necessary to consider the properties of the material, the thickness of the material, the height of the deep-drawing and the diameter of the deep-drawing, so that the number of processes can be determined. The deep drawing fillet radius is relatively small, and it should be trimmed after the deep drawing process is completed.

5. To improve the quality of parts, it is necessary to improve the stability of the process and increase the number of processes.

6. Determine the number of processes according to the manufacturer's actual molding capacity and stamping equipment.

When machining precision stamping parts, if you want to process parts of qualified quality, you should pay attention to the above six points.
