How precision metal stamping solves the difficult problem of skipping scrap in manufacturing-hardware
In the process of precision metal stamping, such as due to the large gap between the mold, the short punch, the influence of the material (hardness, brittleness), the stamping speed is too high, the stamping oil is too viscous or the oil droplets are too fast to cause adhesion, and stamping vibration Dispersion of material scraps, vacuum adsorption and insufficient demagnetization of the mold core can cause scraps to be brought to the mold surface. How to solve this problem? Xiaoshuo will take you to understand: (1) The sharpness of the cutting edge of the precision metal stamping die. The larger the rounded corner of the cutting edge is, the easier it is to cause the scrap to rebound. For thinner stainless steel, the inclined cutting edge can be used. (2) For relatively regular waste materials, the complexity of the waste materials can be increased, or polyurethane ejector pins can be added to the punch to prevent the waste materials from jumping, and scratches can be added on the edge of the die. (3) Whether the gap of the mold is reasonable. Unreasonable mold gaps can easily cause scrap to rebound. For small diameter holes, the gap is reduced by 10%; if the diameter is greater than 50 mm, the gap is enlarged. (4) Increase the depth of entry into the mold. When each station die is stamped, the requirement of the modulus is certain, and the modulus is small, which is easy to cause the scrap to rebound. (5) Whether there is oil stain on the surface of the processed material. (6) Adjust the stamping speed and stamping oil concentration during production. (7) Adopt vacuum adsorption. (8) Demagnetize the punches, inserts and materials. Hardware, 15 years of rich experience in precision metal stamping, 5,000 square meters production workshop, monthly processing capacity of 100+ sets of molds, daily production capacity of 3 million punching times, 16 quality inspections strictly for quality control. The idea that the result of your needs is the result of the work, choose, choose rest assured!
