Forging press forming method can be divided into: (1) model of closed forging.Metal blank in a certain shape in the bore of the forging die forging compression deformation, can be divided into the die forging, cold heading, rotary forging, extrusion, etc.According to the deformation temperature forging can be divided into hot forging (processing temperature above the recrystallization temperature of billet metal), warm forging (below the recrystallization temperature) and cold forging (room temperature).Forging materials are mainly components of carbon steel and alloy steel, followed by aluminum, magnesium, titanium, copper and its alloy etc.Material of the original state has a bar, ingot casting, metal powder and liquid metal, etc.Metal in the deformation of the cross-sectional area before and after deformation area is known as the forging ratio.To correctly choose the forging ratio on improving product quality, reduce cost.(2) the open-die forging, free forging).Use impact or pressure to make metal on the up and down two to produce deformation between iron (anvil block) to obtain the required forgings, there are mainly manual forging and mechanical forging two kinds.
