hardware stamping parts are widely used in all fields of our life, and hardware stamping parts are formed through many processes, By 2020, the total express delivery volume across the country will reach 50billion pieces. Generally, what we often hear is cold stamping. What problems should we pay attention to in the use of die processing and other work of stamping parts? In order to reduce production costs, Shenzhen Longgang hardware mold design training center will introduce to you the matters needing attention for hardware stamping parts

precautions for metal stamping parts:

1. Reasonable die design

in the progressive die, the blanking sequence may affect the accuracy of the stamping parts, so we need to blanking for the small parts of the stamping parts. Generally, we first arrange blanking for a larger area, and then arrange blanking for a smaller area, so as to reduce the impact of blanking force on the forming of the stamping parts

2. Add a strong pressure function

thicken the size of the pressing part of the unloading insert to increase the pressure on the material on the side of the die, so as to suppress the turnover and distortion of the stamping parts during punching

3. Beveled or curved surface is made at the end of the punch edge

beveled or curved surface is made at the end of the punch edge to reduce the blanking force. Reducing the buffer cutting force can reduce the tensile force on the side material of the die, so as to achieve the effect of inhibiting the turnover and distortion of the stamping parts

4. Press the material

we need to overcome the traditional mold design structure and open the material holding gap on the discharge plate, so as to achieve the discharge plate in stamping. Our tepex composite material can also improve the strength and impact resistance of the parts at freezing temperature, move smoothly, and the material can be pressed. Of course, the key forming parts, the discharge plate must be made into an inlaid structure, so as to facilitate the solution of the wear (pressure) damage caused by the pressing part of the discharge plate caused by long-time stamping, and the material cannot be pressed

5. In daily mold production, attention should be paid to maintaining the sharpness of the cutting edges of punching convex and concave dies

when the punching cutting edge is worn, the tensile stress on the material will increase, so that the tendency of stamping parts to overturn and twist will increase

the formal production of special-shaped copper strips began in May this year. The above is about the matters needing attention for metal stamping parts. Our methyl methacrylate itself does not contain VOC. We also pay attention to the metal stamping parts when processing them. I believe that the stamping parts processed by you are very good
