Repair methods for minor problems of metal stamping dies

After long-term use of stamping dies, there will be some problems. We need to pay attention to repair and maintenance. If the stamping die is too serious, it must be produced by changing the die. When the damage is relatively minor, how should the stamping manufacturer repair it? , The following is a brief description. 1. When the metal stamping die is tilted, loosened, and the template is deformed, the integrity of the stamping part will be destroyed when the template is tilted, making the blanking irregular, and the product deformed. First, analyze the problem. The angle of movement is not vertical, which may be a jump between the templates. Into the waste material, it cannot be flattened, the mold can be disassembled and reorganized, and the posture can be re-corrected; the problem of looseness can be adjusted by fine-tuning the gap between the two sides of the mold position to make it just right; replace the deformed template. 2. Metal stamping dies will also have problems such as blanking deflection, stroke interference, and deformation of the die base. The problem of semi-tilted metal stamping parts may be caused by insufficient punch strength and too close distance between the big and small heads, which makes the lateral force unbalanced. At this time, the size of the punch can be shortened or the heel length can be increased, and the protection of the guide plate can be strengthened to enhance its effect; affected by interference, check the correctness of the size and position of the die, and the degree of contact after the combination. The correctness of the mold frame, etc.; one of the simpler methods is to replace the mold base, otherwise, polish and correct the unbalanced part.
