Several outstanding features of precision stamping parts

1. Due to the effect of cold work hardening, the punching surface of high-performance precision stamping parts has greatly improved its surface hardness and strength, and its friction resistance and weather resistance have been improved. It is used as fine-blanking parts such as the gear tooth profile of the moving surface and the friction surface, bushings, etc. , And its lifespan will be improved as a result. 2. Mass-produced precision stamping parts are generally mass-produced and moderately economically produced parts of electromechanical products, which are easy to realize mechanization and automation, including: medium-duty trucks, cars, motorcycles and other products, all of which are made of raw materials Finished parts are punched out in one die without cutting. 3. Complex shape and high precision. Most materials with thickness t>3mm～12.5mm are precision blanking parts for medium and thick plates. The punching surface is straight and smooth, and the quality is comparable to cutting processing, so as to obtain better economic benefits. of. 4. Clear outline, small collapse angle, some hole edge distance and hole spacing (wall thickness) ≤ t, and there are press convex, counterbore, blind hole and hub flange and other forming precision punching, especially the involute with small modulus, Fine-blanking gears with high-precision shapes such as cycloid, triangle, rectangle, trapezoid, etc., are all difficult to manufacture with other processing techniques.
