Stamping process and processing characteristics

Stamping is a forming and processing method that relies on presses and dies to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamping). The most common stamping processes are: slitting and trimming, reverse stretching process, flaring, punching, embossing, embossing, stretch forming, bending, crimping and so on. Stamping processing is also divided into hot stamping and cold stamping. The difference is that hot stamping is suitable for forming, thinning and thickening, tensile strength, and high hardness. Cold stamping processing, in the state of the plate at room temperature, through stamping processing, to achieve product deformation or separation. The quality of stamping processing requires the following points: 1. Dimensional accuracy requirements, precise thickness and uniformity 2. Product shape accuracy, with the characteristics of beautiful, thin, uniform, and strong 3. Surface quality requirements, the appearance of the surface should be smooth, without ripples, and without wrinkles No scratches, no rust spots, smooth and even curve. 4. Stretching requirements, strong rigidity, high uniform elongation of the product 5. Good manufacturability, for the product design structure, during processing, the stamping process and stamping die design are safe, economical and stable, while ensuring high-quality products Stamping processing features 1. Stamping processing production must achieve high efficiency, easy operation, easy to achieve mechanization and automation. 2. The quality of stamping products should be stable. 3. The stamping strength and rigidity are both high. This article address: Previous article: Mold vibration management method
