Abstract

The invention belongs to the technical field of roll forging machining and relates to a roll forging machine. The technical problem of low production efficiency in the prior art is solved. The forge rolling machine comprises a blank feeding-heating mechanism, a blank conveying mechanism and a blank roll forging shaping mechanism which are arranged on a machine base and are connected in sequence, wherein the blank feeding-heating mechanism comprises a blank feeding module and an intermediate frequency furnace connected with the blank feeding module, and the blank feeding module can feed blanks into the intermediate frequency furnace to be heated. The blank conveying mechanism comprises a feeding groove connected with a discharging port of the intermediate frequency furnace, wherein a pulley group is arranged at the bottom of the feeding groove. The blank roll forging shaping mechanism comprises two oppositely-arranged rotary drums in rotary connection with the machine base, wherein a driving motor is arranged on the machine base and is connected with the rotary drums so as to drive the rotary drums to rotate. The forge rolling machine is simple in structure, reasonable in design, high in working stability, capable of achieving continuous production and forming roll forgings in one time and high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of roll forging and relates to a roll forging machine. Background technique [0002] The roll forging machine is mainly used for pre-forging of forgings, and can also be used for final forging. The essence of roll forging deformation is the rolling extension of the blank, and the section of the blank part becomes smaller and the range of the surface increases. When the section deformation is large, it needs to be rolled several times. Its process design is mainly to reasonably determine the amount of reduction, width and extension of roll forging in each working step. They depend on the size of the roll diameter, the shape and size of the pass, the temperature of the blank, and the deformation conditions such as cooling and lubrication. One end of the blank is clamped with a clamp, deformed under the rolling pressure of the first pass of the fan die (primary forming) and withdrawn, and then fed into the mo...
