Free forging is to use impact or pressure between the top and bottom anvil surface metal free deformation in all directions.
Free forging used simple tools and equipment, excellent versatility, low cost. Compared with the casting blank, free forging eliminates the defects such as shrinkage cavity, shrinkage, porosity, make blank has higher mechanical properties.
Forging shape is simple, flexible operation. Therefore, it is important parts on the manufacturing of heavy machinery and has special important meaning.Free forging points by hand free forging and cold forging machine.
Hand free forging production efficiency is low, the intensity of labor is big, only used for replacement or simple, small, small batch production of forgings. In the modern industrial production, the cold forging machine has become the main forging production methods, in the manufacture of heavy machinery, has a special important role in it. And the forging shape and size is mainly determined by the operator's technical level.
