Same as Ruiping washer, what causes the burr + the stamping surface of the product is smooth and clean

The hardware responsible for manufacturing Tongruiping washers said that in the processing and production of flat washers, some burrs are often encountered, which affects quality and efficiency. At the same time, it is insufficient for customers' use. Xiaoshuo sorted out a few points and came to understand together, so as to be more refined in the production of flat washers: 1) Mold assembly errors. If the punch is not perpendicular to the fixed plate or is loose due to wear, or the positioning pin is loose, the correct fixed position of the male and female molds cannot be guaranteed. 2) Poor guiding accuracy. Excessive fit of the mold guides causes the axis of the upper and lower molds to not overlap and affects the uniformity of the stamping gap. 3) Installation error. When the non-guided mold is installed, the position of the upper and lower molds is not accurate, resulting in uneven clearance. The surface of the template or bottom plate of the mold is not clean, or the upper mold screw is improperly tightened, which will cause the working part to tilt. 4) The mold is deformed when it is working. For example, the leakage hole of the punching mattress board is too large, the template under the mold is too thin, and the rigidity of the die is not enough. The gap is affected by the deformation of the mold during the stamping. 5) The gap between the punch guide rails is too large, the parallelism between the bottom surface of the slider and the work surface is not good, or the sliding direction of the slider is not perpendicular to the work surface. 6) When the greater resistance of the flat washer during punching exceeds 80% of the nominal pressure of the punch, it is easy to deform the 'C'-shaped bed for an open punch, so that the upper and lower die axis lines do not coincide. Hardware, 15 years of focus on Tongruiping washer, 5000 square meters production workshop, hundreds of precision processing production equipment, 20000+ sets of customized mold production experience, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, 16 quality inspections Strict checks at all levels. It can quickly solve the time-critical problem of metal stamping parts, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose, rest assured!
