Maintenance essentials for punching and concave molds in stamping parts processing plants

Stamping parts processing plants need to maintain regular molds. What are the maintenance methods for convex and concave molds? Let's briefly talk about it; the stamping parts processing plant should pay attention to the original condition of the mold when disassembling the male and female molds, so as to facilitate the restoration during subsequent mold assembly. If there is a pad or shift, the thickness of the gasket should be engraved on the part and completed. recording. When replacing the punch, try to insert the unloading block and the die to see if it is smooth, and whether the gap between the insert and the die is even, and whether the gap between the die and the punch is even when changing the die. After grinding the punch, the punch is shortened and the gasket needs to be added to reach the required length. It is necessary to check whether the effective length of the punch is sufficient. To replace the broken punch, find out the reason, and check whether the corresponding concave mold has chipping and whether it needs to grind the cutting edge. 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 any movement margin. The assembling die should be placed horizontally, and then set it with a flat iron block such as a copper rod on the die surface to tap it in place. Do not place it obliquely and force it in. 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. After assembling the punch and die core, check the material belt to check whether the parts are installed incorrectly or reversely. Check whether the die and die pads are reversed, whether the blanking hole is blocked, and whether new parts are needed. Stealing materials, whether the material needs to be stolen is enough, and whether the mold needs to be locked tightly. Pay attention to the confirmation of the locking of the stripper plate screw. When locking, it should be cross-locked from the inside to the outside with a balanced force. Do not first tighten one screw and then lock the other screw, so as to avoid the stripper plate tilting and causing the punch to break or The accuracy of the mold is reduced.
