The quality and service life of the mold are mainly affected by the mold material and heat treatment in addition to reasonable structural design and processing accuracy.

[0003] During the production and processing of mold steel, the mold steel is usually deformed due to pressure, load and tension. Therefore, a stress relief device is needed to perform stamping and stress relief treatment on the mold steel to ensure the quality of mold steel processing.

At this time, the vibration block in the vibration component has a certain distance from the corner of the mold steel, and the distance can be adjusted according to different mold steels and specific conditions. The application range is large, and then the second electric telescopic rod is started to drive the fixed plate to fix the mold steel around, so that the mold steel can be limited. However, this design has the disadvantage of being inconvenient to adjust, resulting in the inability of the stress relief device to perform multi-range stamping and stress relief on the mold steel, which limits the use range of the stress relief device, and further affects the effect of the stress relief device on the stress relief stamping of the mold steel, and cannot guarantee the effect of mold steel processing. It is inconvenient to use and cannot meet the actual use needs, which reduces the use efficiency and use effect of the stress relief device. Utility Model Content
