Maintenance of flat metal washers, concave and convex molds of washers + 20,000 sets of customized mold production

Metal flat washers are formed by punching metal raw materials through a washer mold under the pressure of a punching machine. Therefore, the quality of gasket molds and daily maintenance play an important role in production and processing. Xiaoshuo organizes a few maintenance methods to share with you: 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 are pads or shifts, the pads should be engraved on the parts. Record the thickness of the film. 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 change the die, it is also necessary to try whether the gap between the insert and the punch is even. 3. As the punch becomes shorter after grinding the punch, it is necessary to add gaskets to reach the required length. Check whether the effective length of the punch is sufficient. To replace the broken punch, it is necessary to find out the reason, 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 placed on the surface of the die with a flat iron block, tapped it in place with a copper rod, and must not be slanted and forcefully tapped, and 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 the punch and die cores are assembled, check the material tape to see if the parts are incorrectly installed or reversed. Check whether the die and die pads 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. Pay attention to the confirmation of the locking of the stripper plate screws. When locking, it should be balanced and tightened 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 plate to tilt. Cause the punch to break or reduce the accuracy of the mold. Hardware, 15 years of ingenuity and focus on metal flat washers, 20,000+ sets of mold customization production experience, monthly 100+ sets of mold processing capacity, 3 million punching times per day, stamping accuracy up to 0.01mm, and 16 quality inspections strictly. You can quickly solve the time-critical problem of precision stamping parts, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose rest assured!
