Problems solved by technology

Therefore, the upper part of the movable beam and the lower end of the lifting screw of the movable row of work rolls installed on it cannot be connected in a hinged manner, but must be able to slide each other. The lower end of the lifting screw of the movable beam is close to each other, which is unfavorable to the inclination accuracy of the movable beam and the movable row of work rolls
In the roller plate leveling machine with backup rolls, the backup rolls increase the strength and rigidity of the work rolls, but since the contact between the work rolls and the backup rolls is a line contact between two parallel cylinders, there is a large contact stress , resulting in local wear of the work roll

Embodiment Construction

[0016] Fig. 1 is one of the embodiments of the present invention, a seven-roll plate leveling machine, in which 1, 2, 3, 4, 5, 6, and 7 are work rolls, and 2, 4, and 6 are movable row work rolls, without backup rolls Driven by the movable row of work rolls installed on the frame above it and the lifting screw of the bearing seat, the movable row of work rolls can be lifted or tilted along the inner guide plate of the frame, and 1, 3, 5, and 7 are fixed Row of work rolls, installed on the frame, A1, A2 are backup rolls of work rolls 3 and 5, installed on the lower beam or chassis between the two frames, and the plates are at the 2nd, 3rd, 4th, 5th, 6th rolls A total of five times of deformation, elastic deformation at the 6th roller of the discharge, elastoplastic deformation at the 2nd, 3rd, 4th, and 5th rollers, and the reduction decreases in turn, and the plate is downward at the 2nd and 4th rollers Bending, the plate bends upward at the 3rd and 5th rolls, the maximum reduct...

Abstract

The invention relates to roll-type plate flattening machine belonged to forging equipment for metals shaping, which comprises active row work roller that has larger roller diameter, no supporting roller and active beam and less roller number, fixed row work roller with supporting roller and a frame, lifting tilting equipment, balancing equipment, main gear, and electric controller; wherein, it is pin joint between bearing block and bottom end of lifting screw bar in active row work roller. This machine can reduce difference of deflections on upper and down directions and improve flattening precision.

Description

Technical field [0001] The invention relates to a metal material shaping forging equipment-roller straightening machine, in particular to a roller plate straightening machine. Background technique [0002] The existing roller-type plate leveling machine generally has the same roll pitch and roll diameter as the upper row of work rolls and the lower row of work rolls. When the overall inclination of the upper row of work rolls adopts the non-parallel correction process, the deformation of the plate will change from feeding to discharging. Decreasing in order, the ideal state is: the last deformation at the discharge point is elastic deformation, and the rest are elastic-plastic deformation. For example, in the seven-roll plate leveling machine, the 2nd, 4th, and 6th rolls are movable row work rolls, which can be lifted or tilted along the inner guide plate of the frame at the top, and the 1st, 3rd, 5th, and 7th rolls are fixed row work rolls. Underneath, installed in the fra...
