45 steel flat washers, what to do if the production of flat washers is uneven + stamping accuracy reaches 0.01mm

The technician in charge of the production of 45 steel flat washers said that in the production process, many reasons are often encountered that cause unevenness on the surface of the flat washers. So what caused it? How should it be solved? Xiaoshuo sorted out a few solutions, and let’s take a look with you: 1. Inspection and correction of flat washer molds: Stamping molds need to be regularly inspected and maintained to reduce the occurrence of bumps and maintain a stable state. The usual method is to use samples to check the bonding scratches and processing surfaces of the blank holder (die fillet, punch fillet). 2. Inspection and correction of the shearing step: The reason for the unevenness after the shearing process is that iron powder is produced during the shearing process. Therefore, the iron powder must be observed before punching to avoid the occurrence of unevenness. 3. Check the cut surface: When cutting the coil material, the wear and breakage of the cutting die will produce a lot of tiny iron powder attached to the cutting edge, so the double cut surface must be checked in the material area or the press line before stamping production, and cleaned in time The sheet is deburred. Hardware, 15 years of focusing on 45 steel flat washers, 5,000 square meters production workshop, hundreds of precision processing production equipment, 20,000+ sets of precision stamping die customized production experience, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, 16 quality Strictly check every layer of inspection. It can quickly solve the urgent problem of flat washer time, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose rest assured!
