In the progressive die, the shape of the punch is formed by punching the spare material around the punch. The influence of blanking force is the main reason of blanking and distortion. During blanking, because of the blanking gap, the data is stretched on one side of the die (the data is warped upward) and…
In the processing of precision hardware parts of aluminum profile drawing and bending encountered in the surface defects and other problems of the solution, Huiyuan precision hardware to share with you including the adjustment of the curvature of the molding profile, surface defect treatment, stretching and bending after the distortion treatment, perpendicularity over the treatment…
The reasons for the concave and convex metal stamping parts are mostly caused by the dust or iron filings attached to the appearance of raw materials or molds. It makes the appearance of products low in character and also makes the productivity drop dramatically. So how can we avoid this problem? The following is based…
Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce work pieces with undulating or hemming that are difficult to make by other means to improve their rigidity. Due to the use of precision mold, so the workpiece accuracy can reach micron level, high repeatability, the same specifications.…
