Narrow-sided flat washers, how to maintain flat washers concave and convex mold + 20000+ sets of stamping die customization experience

The hardware manufacturer responsible for the manufacture of flat washers with narrow sides said that flat washers are formed by stamping metal raw materials through a washer mold under the pressure of a punch press. Therefore, the quality of gasket molds and daily maintenance play an important role in production and processing. Xiaoshuo organizes several maintenance methods to share with you: 1. When disassembling the convex and concave molds, you should pay attention to the original condition of the mold to facilitate the restoration of the subsequent mold assembly; if there is a pad or shift, the pad should be engraved on the part. 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. 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 the punch and die cores are assembled, check the material belt to check whether 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 screw. 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 to avoid tilting the stripper plate. Cause the punch to break or reduce the accuracy of the mold. Hardware, 15 years of focus on narrow-side flat washers, 20,000+ sets of customized mold production experience, monthly processing capacity of 100+ sets of molds, 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 to rest assured!
