Washer manufacturer, how to solve the burr caused by the excessive spacing of the stamping die

In the production process of the flat washer, the gasket manufacturer may have too large mold intervals due to the design, processing, and wear of the stamping die, and the phenomenon of excessive burrs on the flat washer produced by the stamping. How do you encounter this problem? Solve it? Xiaoshuo will work with you to understand: 1. Processing and manufacturing errors. When the processing of die parts does not meet the requirements of the drawings, it will affect the gap after assembly. If the parallelism of the bottom plate is not good, the convex and concave molds have reverse tapers, and the deviation of the size of the convex and concave molds will cause the punching gap to be unreasonable. 2. Mold assembly error. If the punch and the fixed plate of the punch are not assembled perpendicularly, the guide part has a large gap, and the punch and concave molds are assembled out of concentricity, all of which can change the punching gap. 3. The accuracy of the punch is poor. If the gap between the punch guide rails is too large, the bottom surface of the slider and the surface of the worktable are not parallel, or the stroke of the slider is not perpendicular to the press table, the rigidity of the worktable is poor, and the deflection during stamping can cause the gap. The change. 4. The installation error of the mold. If the surface of the bottom plate of the die soil is not cleaned during installation, or the method of fastening the upper die of the large die is improperly, the upper and lower die of the die are installed out of center (especially the die without guide post), causing the working part to tilt. 5. The structure design of the mold is unreasonable. If the rigidity of the die and its working part is not enough, deformation occurs during the stamping process and affects the change of the gap; or the design does not pay attention to the balance of the punching force, and side pressure is generated during the stamping process, causing the die to move. Hardware, 15 years of ingenuity and focus on washer manufacturer, 20,000+ sets of mold customization production experience, monthly 100+ sets of mold processing capacity, 3 million punching production capacity per day, stamping accuracy up to 0.01mm, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose to rest assured!
