How do stamping parts manufacturers maintain concave and convex molds

Everyone knows that the stamping die production process requires frequent maintenance of machines and equipment, which is conducive to improving the life of the die, improving the efficiency of production and saving costs. Next, let us understand how to maintain the concave and convex mold as a qualified stamping parts manufacturer. 1. When disassembling the convex and concave molds, pay attention to the original condition of the mold so that it can be easily restored during subsequent mold assembly; if there is padding or displacement, the thickness of the gasket should be engraved on the part and recorded. 2. To replace the punch, try to insert the stripping block and the die to see if it is smooth, and whether the gap between the insert and the die is even; to replace the die, it is also necessary to try whether the gap between the insert and the punch is even. 3. In view of the shortening of the punch after grinding the punch, it is necessary to add gaskets to reach the required length, and check whether the effective length of the punch is sufficient. It is necessary to find out the reason for replacing the broken punch, and check whether the corresponding concave mold has chipping and whether it needs to grind the cutting edge. 4. When assembling the punch, check whether the gap between the punch and the fixed block or the fixed plate is sufficient. If there is a press block, check whether there is a margin for movement. The assembling die should be placed horizontally, and then a flat iron block should be placed on the surface of the die, and a copper rod should be used to tap it in place. Do not knock it in at an oblique angle. The bottom of the die should be chamfered. After installation, check whether the surface of the concave die is even with the surface of the die. 5. After assembling the punch and the die core, check the material tape to see if the parts are incorrectly installed or reversed, check whether the die and the die pad are reversed, whether the blanking hole is blocked, and replace it with a new one. Whether the parts need to be stolen, whether the materials need to be stolen enough, and whether the mold needs to be locked tightly. 6. The stamping parts processing plant should pay attention to the locking confirmation of the stripper plate screws. When locking, they should be balanced and cross-locked from the inside to the outside. Do not lock one screw first, and then lock the other screw, so as not to cause The stripper is tilted, causing the punch to break or reduce the accuracy of the mold.
