How to suppress the twisting and distortion during the production of precision stamping parts? Dongguan Hardware will tell you

How to restrain the turning and distortion of precision stamping parts during the production process of precision stamping parts? Dongguan Hardware will tell you. 1. Reasonable mold design. In the progressive die, the arrangement of the blanking sequence may affect the forming accuracy of the stamping parts. For the blanking of small parts of stamping parts, generally a larger area of u200bu200bpunching is arranged first, and then a smaller area of u200bu200bpunching is arranged to reduce the impact of the punching force on the forming of the stamping part. 2. Hold down the material. Overcoming the traditional mold design structure, the discharge plate is opened with a material gap (that is, when the mold is closed, the discharge plate is attached to the concave mold, and the discharge plate and the concave mold where the material is contained-0.03, 0.05mm). In this way, the unloading plate moves smoothly during stamping, the gap is the material thickness t, and the material can be compressed. The key forming part, the unloading plate must be made into a block-type structure to facilitate the solution of the wear (compression) loss of the pressing part of the unloading plate caused by long-term stamping, and the material cannot be compressed. 3. Add strong pressure function. That is to increase the size of the press part of the unloading insert (normal unloading insert thickness H+0.03mm) to increase the pressure on the material on the side of the die, so as to prevent the stamping part from turning over and twisting during punching. 4. The end of the punch edge is trimmed with a bevel or arc. This is an effective way to reduce cushioning power. By reducing the buffer cutting force, the tensile force on the side material of the die can be reduced, so as to achieve the effect of suppressing the turning and twisting of the stamping parts. 5. In daily mold production, care should be taken to maintain the sharpness of punching convex and concave die cutting edges. When the punching edge is worn, the tensile stress on the material will increase, and the tendency of the stamping part to turn over and twist becomes greater. 6. Unreasonable or uneven blanking clearance is also the reason for the distortion of precision stamping parts, which needs to be overcome.
