Stamping process and characteristics of stamping parts

If stamping is classified according to the process, it can be divided into two major processes: forming and separating processes. The index of the forming process is to make the sheet metal produce plastic deformation without breaking the blank, and make the workpiece of the required shape and size. The separation process is also called blanking, and its purpose is to separate the stamping parts from the sheet along the pre-set profile line, while ensuring the quality requirements of the separation section. In practical production, multiple processes are often summed up and operated on one workpiece. Blanking, vertical, shearing, spinning, and replacement are frequently used stamping processes. The stamping parts are mainly made of metal or non-metal sheet materials by means of the pressure of a press machine and stamped and processed by a stamping die. It mainly has the following characteristics: The appearance and extension of the stamping sheet of 5 gold stamping parts are subject to the quality of the stamping waste. The impact is great, and the thickness of the stamping materials is roughly and uniform; the appearance is bright, no spots, no scars, no scratches, no appearance cracks, etc.; compliance with uniform strength, no appreciative bias; high uniform stretch rate; low yield ratio; processing The hardenability is low; the stamping parts have a high dimensional accuracy, which is uniform and common with the mold parts, and has good interchangeability. No further machining is required to meet the general assembly and use requirements; the stamping parts are made by pressing under the premise of low material consumption. The parts are light in weight and rigid, and the sheet material is plastically deformed. , The internal layout structure of the metal has been improved, so that the strength of the stamping parts has been improved; in the stamping process, because the heart of the material is not damaged, the stamping parts have a better psychological quality, and the exterior is smooth and beautiful. Electroplating, phosphating and other mental processing provide arbitrary conditions.
