Roller type leveling machine

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...
