How to judge the section quality of metal stamping parts?

How to judge the section quality of metal stamping parts? First of all, we have to understand what are the main factors that affect the blanking section, so that it is easy to find a way to judge. That is to say, we can judge the quality of the section of the metal stamping parts according to the width of the bright belt, the height of the burr and the flatness. In actual production, the larger the bright band size of the blanking section, the better, and the smaller the burr height size, the better; to obtain a blanking part with good blanking section quality, it is necessary to take into account other aspects of the blanking part forming process for optimal distribution; When the punching section is not flat and has a concave arc surface, the main reason is that the straight wall edge of the die has a reverse taper, which can be adjusted by grinding the die; when the punching section of the metal stamping part is rough, the slope is obvious, and there is For longer burrs, the main reason is that the gap between the convex and concave molds is too large, which can be improved by adjusting the gap between the convex and concave molds and sharpening the edge; when the punching section of the metal stamping part has obvious slope and burrs on one side, the quality of the surrounding section is not good. When it is uniform, the main reason is that the gap between the convex and concave molds is not uniform, and the center/center line of the convex and concave molds do not overlap. This can be improved by checking the gap and improving the assembly accuracy of the metal stamping parts. 【related suggestion】
