Stamping parts and stamping introduction

Cold stampings are generally no longer machined or require only a small amount of machining. The accuracy and surface condition of hot stampings are lower than that of cold stampings, but they are still superior to castings and forgings, and the amount of cutting is small. Stamping is an efficient production method. It adopts composite molds, especially multi-station progressive molds. It can complete multiple stamping processes on one press, and realize the whole process of unwinding, leveling and punching to forming and finishing. Automatic production. High production efficiency, good working conditions, low production costs, and generally can produce hundreds of pieces per minute.

Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with ribs, ribs, undulations or flanging that are difficult to manufacture by other methods to increase their rigidity. Thanks to the use of precision molds, the precision of the workpiece can reach micron level, and the repeatability is high and the specifications are the same. It is possible to punch out the holes and the bosses.

Stamping is mainly classified according to the process, and can be divided into two major categories: separation process and forming process. The separation process is also referred to as blanking, and its purpose is to separate the stamped parts from the sheet along a certain contour line while ensuring the quality requirements of the separated sections. The surface and intrinsic properties of stamping sheets have a great influence on the quality of stamped products. The thickness of stamping materials is required to be precise and uniform. The surface is smooth, no spots, no flaws, no scratches, no surface cracks, etc.; yield strength is uniform, no obvious Directionality; high uniform elongation; low yield ratio; low work hardenability.
