The forging machine is forging the metal blank by using a forging machine to make plastic deformation. The internal structure of the powder forging is uniform and there is no segregation. It can be used to manufacture small gears and other workpieces to obtain forgings with certain mechanical properties, certain shapes and sizes. The processing method, the material is solidified, crystallized, flowed, plastically deformed and formed under pressure, and the forgings of the desired shape and performance can be obtained. The forging materials of the coiling machine are mainly carbon steel and alloy steel of various compositions. .
The forging machine can eliminate the loose and welded holes of the metal by forging. The mechanical properties of the forgings of the coiling machine are generally better than those of the same material. The forging of the flat machine can be divided into free forging, die forging and cold rolling according to the forming method. Radial forging, extrusion, forming and rolling, roll forging, ramming, etc., important parts of the coiling machine machinery with high load and severe working conditions, except for the shape of the simple rolled sheet, profile or welded parts. More forgings are used.
The deformation of the blank under the pressure of the coiling machine is basically free from external limitation. The size and surface defects of the forged part are inspected. The forging is heat treated to eliminate the forging stress, forming, rolling, rolling and boring. There is a relative rotational movement between the tool and the blank, and the blank is subjected to point-by-point and asymptotic pressurization and forming. Different forging methods have different processes. The forging of the coiling machine can be divided into cold forging according to the temperature of the blank during processing. And hot forging, the recrystallization temperature of steel is about 460 ° C, but 800 ° C is generally used as the dividing line, higher than 800 ° C is hot forging, between 300 ~ 800 ° C is called warm forging or semi-hot forging.
