Metal Spinning process

Fix the flat blank or preformed blank to the rotating mandrel, apply pressure to the blank with a rotary wheel, and the rotary wheel is fed axially at the same time, and after one or more processing, various thin-walled hollow rotary products are obtained. process method.

During spinning, the contact area between the rotary wheel and the blank is very small, and the processed material only partially undergoes plastic deformation, and the deformation resistance is small. Large-scale products can be processed with small-tonnage equipment. It is ideal for manufacturing hollow cones, cylindrical parts, hemispheres and thin An effective method for precision products such as wall pipes. Spinning products have high precision, good mechanical properties and a wide range of sizes. Spinning tools and molds are simple and easy to replace; for some products, the production cost is lower than other methods. The main disadvantages are long production hours, low output and limited varieties. It is suitable for the production of small batches and multi-variety products.
