Problems solved by technology

The gear drive uses a reducer to drive a pair of gears installed on the two lower work rolls to drive the two lower work rolls, so that a bending moment is generated on the lower work rolls, which affects the long-term work of the lower work rolls
The universal joint drive uses the universal joint to connect with the reducer and the two lower work rolls respectively to drive the two lower work rolls. This transmission method takes up a lot of space and the structure is not compact enough.
At the same time, the two transmission modes are both driven on the same side. Since the two lower work rolls are relatively long, a torsion angle will be generated during rotation, and the rolled sheet will easily form a wrong side.

Abstract

The invention relates to a bottom working roll transmission device of a super wide lapping machine, belonging to the field of metal forging and pressing machinery and especially belonging to the technical field of the transmission of the super wide lapping machine. The bottom working roll transmission device of the super wide lapping machine comprises a base plate and two bottom working rolls distributed on the base plate, wherein one end of one of the two bottom working rolls is connected with a working roll actuating mechanism, and the other end of the other one of the two bottom working rolls is connected with another working roll actuating mechanism; the end parts of output shafts of speed reducers of the working roll actuating mechanisms are provided with homocentric inner holes, the end parts of the two bottom working rolls are arranged in the inner holes, and the outer sides of the output shafts of the speed reducers are provided with expanding and tightening discs. The invention can overcome the technical defect and prevent the bottom working rolls generating bending moments and has compact structure.

Description

technical field [0001] The invention relates to the technical field of transmission of forging machines, especially ultra-wide plate bending machines. Background technique [0002] The transmission mode of the existing plate rolling machine adopts gear transmission or universal joint transmission. The gear drive adopts a reducer to drive a pair of gears installed on the two lower work rolls to drive the two lower work rolls, so that a bending moment is generated on the lower work rolls, which affects the long-term work of the lower work rolls. The universal joint drive uses the universal joint to connect with the reducer and the two lower work rolls respectively to drive the two lower work rolls. This transmission method takes up a lot of space and the structure is not compact enough. At the same time, these two transmission modes are both driven on the same side. Since the two lower work rolls are relatively long, a torsion angle will be generated during rotation, and the ...
