Analysis on the Causes of the Breaking and Wrinkles of Stamping and Drawing Parts

For sheet stamping and drawing parts, let’s discuss in detail the main reasons for the fracture and wrinkles in the drawing process, so that everyone can have a comprehensive and in-depth understanding of this problem, so as to effectively solve the problem; Reason 1: The die gap of the stamping and drawing parts is unreasonable. If the die gap is too small, the material thickness will become thinner, which will cause the extension force to be too large, which in turn will cause the thin plate stamping and drawing parts to break. , If the gap is too large, it will cause the stretching part to wrinkle during the stretching process, thereby increasing the friction resistance. Furthermore, the tensile member will also experience breakage. The second reason for the fracture and wrinkles of the stamping and drawing parts: the second is that the smoothness is not good. If the smoothness is not good, it will increase the friction resistance, resulting in strains or even fractures on the surface of the sheet stamping and drawing parts. At the same time, the service life of the mold will be shortened. The third reason for the fracture and wrinkles of the stamped drawing parts: the blanking pressure is inappropriate, too large or too small. If the blank holder pressure is too large, the frictional resistance between the sheet stamping and drawing part and the die will be increased, and the drawing part will be broken. When the blanking pressure is too small, the stamped and stretched parts will appear wrinkles, making their surface uneven or even broken.
