How to solve the punching size of the metal stamping parts does not meet the request
In the production process of metal stamping parts, we will encounter situations where the punching standard is too large or too small, and the difference between the punch standard and the punch standard is large. In order to deal with such effects, we have to consider the processing standards and processing of the forming convex and concave molds. Accuracy and blanking are special, and we need to consider the following aspects. 1. In the production of metal stamping parts, if the blanking of the punching parts occurs during the punching, it is necessary to study the punching edge, and pay attention to check whether the blanking area is reasonable. The stamping parts become unstable during bending, mainly for U-shaped and V-shaped bending, guide the stamping parts before bending, guide the position beside the bending process, and press the data beside the bending process to prevent the stamping part Slippage during bending is the key to the treatment effect. 2. In the production of metal stamping parts, the tensile stress on the materials increases, and the tendency of stamping parts to turn over and misunderstand increases. When turning over, the punching standard will become smaller. The strong pressure on the material causes plastic deformation of the material, which will cause the punching standard to become larger. When the pressure is increased, the punching standard will become smaller. 3. In the production of metal stamping parts, if the end is trimmed with a bevel or arc, the punching force is likely to be turned over and misunderstood due to the slowdown of the punching force. Therefore, the punching standard will become larger. However, the end of the punch is three-dimensional, and the punching standard will definitely become smaller.
