The roll forging machine is a forging process that uses a pair of fan-shaped dies rotating in opposite directions to make the blank produce plastic deformation, so as to obtain the required forging or forging stock. In the process of roll forging deformation, after the blank is compressed by the roll forging die in the height direction, most of the metal flows along the length direction of the blank, except for a small part of the metal flowing horizontally.Therefore, the essence of roll forging deformation is the extension deformation process of billet under pressure, which is suitable for the process of reducing the cross-section of billet, such as the stretching of shaft parts, the grinding of slab and so on.In industrial applications, roll forging can be used as a blank making process before die forging to provide forging blanks for long shaft forgings, or to realize the main forging forming process on a roll forging machine or to roll forgings directly.
The roll forging process has the characteristics of both forging and rolling, with high product precision, low surface roughness and good forging quality.Continuous rotation of roll forging, high production efficiency, simple equipment structure, low requirements for plant and foundation, long service life of the die, less relative sliding between metal and the die in the static pressure process of roll forging, and no need of processing after the precision roll forging;The roll forging process is a gradual and continuous deformation process, and the die is only in contact with a part of the blank at each moment of deformation, so only equipment with small tonnage is needed; and the process is simple, has no impact, vibration and the like, has good working conditions, is easy to realize automation,
