Hardware stamping parts are often used in our lives, and there will be damage during use, such as parts that are not fixed, loose, pulleys, etc. First, add a strong pressure function: that is, thicken the size of the unloading insert pressing part to increase the pressure on the material on the concave die side, so as to inhibit the turning of the Metal Stamping parts and twisting deformation during punching. Second, press the material: overcome the traditional hardware stamping die design structure, and open the capacity gap on the unloading plate. In this way, the unloading plate in the hardware stamping parts moves smoothly, and the material can be pressed tightly. The key forming part, the discharge plate, is made into an inlaid structure to facilitate the solution of the wear and tear caused by long-term stamping of the discharge plate pressing part, and the material cannot be pressed. Third, reasonable hardware die design: In the progressive die, the arrangement of the cutting sequence may affect the forming accuracy of the stamping part. For the cutting of the small parts of the stamping part, it is generally arranged to cut the material in a larger area first, and then arrange the punching and cutting of a smaller area to reduce the impact of the punching force on the forming of the metal stamping part.
