Abstract
The invention discloses a working roll changing auxiliary device of a four-high reversing rolling mill used for steel belts. The device comprises a rolling mill stand and a mounting base. A first transmission shaft and a second transmission shaft are movably connected between the rolling mill stand and the mounting base. The first transmission shaft and the second transmission shaft are cooperatively connected with a driving portion. The first transmission shaft and the second transmission shaft are arranged in parallel. The inner side of the rolling mill stand is provided with an upper working roll and a lower working roll. The first transmission shaft is connected with the upper working roll. The second transmission shaft is connected with the lower working roll. Through the above method, the working roll changing auxiliary device of a four-high reversing rolling mill used for steel belts can improve working efficiency of a rolling mill, reduce roll changing time, reduce labor intensity, and the device is convenient in operation, simple in structure, and is safe and reliable.
Description
Technical field
The present invention relates to cold rolling band steel field, particularly relate to a kind of steel band four roll reversing roller work roll changing servicing units.
Background technology
Prior art reduce the number of single stand four-roller cold rolling mill work roller, the roll change of backing roll operates on two-layer changing track for roll.The surface quality of cold-rolled strip depends primarily on the surface of working roll, and in the operation of rolling, working roll is squeezed heating, and wearing and tearing are large, so need frequent roll change.The working roll driven type four-high reversing mill that current most domestic cold rolling mill uses, upper and lower power transmission shaft is exactly that simple screw mandrel supports, and when needs roll change by up-down adjustment nut, wastes time and energy.Working roll is after rolling-mill housing pull-out, and power transmission shaft does not effectively support, and the working roll difficulty newly changed is fitted in lower drive shaft.
