The technology and characteristics of spinning in the stamping process

Professional stamping parts processing manufacturers have many different processing methods in the stamping process, and spinning is one of them, so what are the spinning processes? What are its characteristics? Let's take a look below; 1. The spinning process is usually to clamp the metal sheet on the spinning machine, the spindle drives the blank and the core to rotate, and then applies pressure to the rotating blank. The local plasticity is gradually extended to the entire blank to obtain various shapes of hollow rotating body stamping parts. 2. Spinning can be formed into rotating bodies such as cylindrical, conical, parabolic or other curved shapes, and can also process stamped parts with relatively complex shapes. 3. The spinning forming has a wide range of applications. The spinning process can be used for the workpieces of the rotating body, but the spinning forming also has a drawback, that is, the production efficiency is relatively low. Most of them are used for small batch production, and the cost will be higher than that of ordinary stamping parts. high. Among spinning materials, carbon steel, aluminum and stainless steel account for the largest proportion. Fourth, the classification and characteristics of rotary processing; usually divided into: deep drawing spinning, shear spinning (conical thinning spinning), cylindrical thinning spinning, necking, bulging trimming, curling, and inward flanging , Corrugation or beading and surface finishing, etc. 5. Metal materials suitable for spinning are: 1), carbon steel 2), aluminum, aluminum alloy 3), stainless steel 4), copper, brass 5), silver 6), nickel alloy 7), titanium, molybdenum , Tungsten, tantalum, niobium and other difficult-to-deform metals 8), of which carbon steel, aluminum and stainless steel account for the largest proportion, more than 80% of the overall processed materials.
