How to prevent stamping parts from turning over and twisting

When stamping parts are produced in stamping processing plants, stamping parts are often found to be turned over and twisted. In fact, through reasonable production control, this problem can be avoided. So, in the production process, how can the stamping factory avoid turning and distortion of stamping parts? The precise author will explain next. 1. Reasonable stamping die. In the stamping die, the distribution of the blanking sequence may endanger the precision of stamping forming. For the blanking of the fine parts of the stamping parts, generally the shearing blanks with a large total area are distributed first, and then the shearing blanks with a smaller total area are allocated to alleviate the damage of the punching force to the forming of the stamping parts. 2. Compact the raw materials. Get rid of the traditional stamping die structure, and give a gap in the discharge plate (that is, when the mold is closed, and the raw material can be clamped. For important forming parts, the discharge plate must be made into a block structure for convenience Deal with the wear (compression) loss caused by the pressing part of the discharge plate caused by the long-term stamping die, and the raw material cannot be clamped. 3. The strong pressure function is added. That is, the thickening specification of the discharge part of the discharge insert (all normal The thickness of the unloading insert is H 0.03mm) to increase the working pressure on the raw materials on the cavity side, thereby preventing the stamping parts from turning over and distorting during shearing. 4. The top of the knife edge of the mold base is trimmed into a slope or arc. It is A reasonable way to alleviate the punching force. Relieving the cold punching pressure can relieve the tensile force on the raw material on the cavity side, and then achieve the actual effect of restraining the stamping parts from turning over and distorting. 5. Pay attention to maintenance during mold processing. Maintain the sharpness of the cutting convexity and the cavity knife. When the cutting knife is damaged, the tensile stress on the raw material will expand, and the stamping parts will cause turning and distortion. 6. The cold stamping gap is unscientific or the gap is not scientific. Uniformity is also the cause of overturning and distortion of stamping parts, which needs to be overcome.
