1. Stamping performance

The raw materials must be able to be stamped into precision parts at high frequency and low cost, which makes the materials and molds have special properties.

2. Plate size accuracy

Mold calibration is usually a time-consuming task, requiring a large number of workpieces to be stamped and reducing any maintenance process, so the optimal design and accurate manufacturing of the mold are very important. Of course, materials are also important. If the stamping is free of burrs, it should be manufactured to a more accurate width tolerance.Copper alloy springThe correct orientation of the plate as it enters the mould is equally important. In order to keep the elastic force fluctuating within a small range, it is very important that the thickness tolerance of the entire sheet in the longitudinal direction must be as accurate as possible. For curved components, the thickness tolerance of the plate also has a great influence on the accuracy. If the error is too large, the mold must be corrected in time.

3. Stability of mechanical properties

The mechanical performance and dimensional accuracy requirements are similar, and the function and dimensional accuracy of the connector assembly are affected by the overall strength characteristics. When the error is too large, it is necessary to adjust the die and bending die.

4. Internal stress elimination

It is very important to reduce the internal stress generated during the rolling and stamping process to a low level. The stress inside the plate cannot be recognized from the appearance, and it will be released after stamping, resulting in deformation of the stamping parts. The stamping results are related to the die and material. Guide rail asymmetry or grinding error of cutting surfaceCopper alloy springMold error will cause its deformation.

5. Tissue homogenization

The homogenization of the whole plate structure is of great significance to the characteristics of the stamping parts and the stamping process. When the microstructure of the work-hardening alloy is a single phase, its impurities should be reduced as much as possible, and the age-hardening alloy must have microstructure precipitation. In this case, the precipitated tissue should be as fine and evenly distributed as possible.

6. Die wear

Depending on the shape of the stamped part or the characteristics of the applied material, before polishing the edge of the die-cut surface again,Copper alloy springThe service life of the mold is different. But usually, the mold material must withstand about 2 million to 4 million impacts before it can be ground again. If the service life is too short, the cause may be the hard surface of the board or the precipitation of hardened structures, especially age-hardening materials.

This kindCopper alloy springThe surface film is mainly monovalent copper oxide, the same color as the substrate. Tin oxide may be present on the surface of tin bronze in addition to copper oxide. This corrosive oxide film is produced during the annealing process due to the inflow of impure protective gas and should be prevented. Once this occurs, it must be removed with a special pickling solution.

The hard tissue precipitates produced in some aging alloys can cause severe wear of copper alloy spring molds. These precipitates should be distributed as evenly and lightly as possible to reduce mold wear.
