Free forging productivity is low, the processing margin is large, but the tool is simple, versatile, it is widely used for forging shape simple single piece, small batch production forging. Free forging equipment with air hammer, steam - air hammer and hydraulic press, respectively, suitable for small, medium and large forging production. Die forging high productivity, simple operation, easy to achieve mechanization and automation. Die forging size accuracy, mechanical processing margin is small, forging the fiber structure distribution is more reasonable, can further improve the service life of parts.
Free forging the basic process: free forging, the shape of the forging is through some basic deformation process will gradually forging the blank. The basic processes of free forging are upsetting, drawing, punching, bending and cutting.
