Compared with castings and forgings, Metal Stamping parts have the characteristics of thin, uniform, light and strong. Stamping can produce workpieces with ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of molds, the accuracy of the workpiece can reach the micron level, the specifications are consistent, and holes, bosses, etc. can be punched out. This or that problem may occur in the production of stamped parts, so let‘s find out today. Common problems in the production of metal stamping parts: 1. The closing height of the die for precision metal stamping parts is too low, and the cutting edge of the punch is too long to adjust the closing height; 2. The edge of the punch is not sharp and re-grind the edge; I. The surface of the punch is strained, and the force is uneven when removing the material. Replace the punch; 3. The lower die waste blocks the knife edge, causing the punch to break and re-drill the large blanking hole, so that the blanking is smooth; 4. The fixed part (splint) of the punch and the guide part are trimmed or re-wire cut into the block to make the punch go up and down smoothly (plate) offset; 5. The punch is too thin, too long, and the strength is not enough to replace the punch type; 6. Improper positioning of the stamping material causes the punching punch to cut unilaterally , adjust the positioning or feeding device due to uneven force fracture; 7, the plate guide is poor, causing the punch to be unilaterally stressed and repaired to the plate gap; 8, the punch knife edge is too short, and the punch is replaced with the interference of the plate, increasing the length of the knife edge part; 9, the punch is not fixed well, and the punch is re-fixed up and down so that it cannot move up and down; 10, the punch hardness is too high, and the punch material is not correct. Replace the punch material and adjust the heat treatment hardness. The above is provided by EMAR for you about the problems that will occur in the production process of metal stamping parts. After understanding, the problems can be reduced and work efficiency can be improved. If you need to know the problems of other stamping parts, please continue to follow us.
