The main advantage of pressure forging compared to drop forging is its ability to deform the entire workpiece. Drop hammer forging generally deforms only the surfaces of the workpiece in contact with the hammer and anvil; the interior of the workpiece will remain relatively undeformed.
The forging hammer belongs to a kind of free forging equipment. It is a forging machine that uses the kinetic energy generated by the falling motion of the hammer to continuously hit the workpiece blank to produce plastic deformation.
The double-arm (arch type) free forging electro-hydraulic hammer converts the potential energy of the hammer head into the kinetic energy of the hammer head, thereby striking the forging and performing work.
