A kind of cold rolling mill work roller side bearing device of the present invention, is characterized in that; Described collateral runner roller footpath is 0.8 ~ 1.2 times of working roll roller footpath, and the roller footpath of described backing roller is 1/2 ~ 2/3 of collateral runner roller footpath.
The course of work of cold rolling mill work roller side bearing device of the present invention is: during as-rolled condition, drive oil motor, drive worm-and-wheel gear, worm-and-wheel gear drives screw mechanism, screw mechanism drives mobile device, mobile device moves forward and leans on the walking beam of oscillating rod device, promotes walking beam and drives collateral runner system to side oscillation in milling train, make collateral runner system act on upper and lower working roll both sides respectively.During roll change state, drive oil motor to retract, drive mobile device retraction, the walking beam of oscillating rod device moves to backswing under hydraulic cylinder effect, makes collateral runner system shift out milling train window together, ensures the normal replacing of working roll and intermediate calender rolls.
Before normal rolling, first drive outlet side backing roll and be positioned at desired location (by two displacement transducer feedback signals) by displacement closed-loop control.Then the collateral runner of Driver Entry and by pressure closed loop control be positioned at desired location (by pressure sensor feedback signal), auxiliary control (by the displacement transducer feedback signal) of displacement makes entrance side supporting arrangement and outlet side supporting arrangement clamp working roll, ensures that working roll is operationally positioned at the fixed position of rolling outlet side all the time.
The invention has the beneficial effects as follows: ultra-thin in rolling, superhard cold-strip steel, when work roll diameter is less, the forward and backward tension force of band is large, the working roll of minor diameter can be made to produce the bending of horizontal direction, because working roll side bearing device can act on upper and lower working roll both sides when rolling, prevent working roll from producing the bending of horizontal direction, keep cold rolling mill in stable condition, be conducive to controlling finished product Strip Shape and surface quality.
This device has novel structure, the operation of rolling is stablized, the good product quality of rolling, advantages of simple structure and simple, will produce positive social benefit and significant economic benefit.
