What information can the stamping parts processing plant see on the scrap?

In the process of producing stamping parts, stamping parts processing plants cannot avoid the occurrence of waste, so what processing problems can we see in the waste? The waste that appears in the stamping parts processing plant is essentially the reverse image of the forming hole, that is, the same part at the opposite position. By checking the waste, you can judge whether the gap between the upper and lower molds is correct. If the gap is too large, the waste will appear rough and undulating. The fracture surface and a narrow bright zone area. The larger the gap, the larger the angle between the fracture surface and the bright zone area. If the gap is too small, the waste will show a small angle fracture surface and a wide bright zone area; too large a gap will result in a larger curl and edge The torn hole makes the profile slightly protruded with a thin edge. A gap that is too small will result in a slightly curled edge and large-angle tearing, resulting in a more or less vertical profile to the surface of the material; an ideal waste material should have a reasonable collapse angle and a uniform bright band, so as to keep the impact pressure to a minimum And form a neat round hole with very few burrs. From this point of view, extending the life of the mold by increasing the gap is at the expense of the quality of the finished hole; Recommended article: Several methods to adjust the gap between the molds of metal stamping parts : What's the problem with the surface roughness of stamping parts?
