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.
