The invention discloses a roll gap adjustment device which is arranged on a box body of a rolling mill. The roll gap adjustment device comprises an adjustment shaft and a spring locating pin, wherein a locating ring is arranged on the adjustment shaft, and internal splines are formed in one end of the adjustment shaft, and are fit with external splines in an adjustment screw rod on a roll box. When the roll box is mounted or dismounted, the adjustment shaft is moved to allow the splines to be combined or separated, a ball in the spring locating pin is clamped into the locating ring, and the adjustment shaft is prevented from loosening. The roll gap adjustment device is simple and reliable in structure; through spline connection, quick mounting and dismounting can be realized; a transmission gap is reduced; and the roll gap adjustment accuracy is improved. The invention further discloses the rolling mill employing the roll gap adjustment device. Compared with the original gear engagement of a gear, through the connection between the splines and a roll box roll gap adjustment mechanism, the gap is smaller, and the accuracy is higher.
Description
technical field [0001] The invention relates to the technical field of steel rolling equipment, in particular to a rolling mill and a roll gap adjustment device thereof. Background technique [0002] As the main equipment on the steel hot rolling production line, the rolling mill is used to roll the blank into shape. Among them, the roll is an important part on the rolling mill, and the steel is rolled by the pressure generated when a pair or a group of rolls roll. According to the actual production situation, the roll gap of the roll needs to be adjusted accordingly. [0003] At present, in the roll gap adjustment structure, the adjustment shaft cooperates with the adjustment screw rod in the form of a gear. [0004] But the adjustment accuracy of the existing equipment is not ideal enough. Contents of the invention [0005] In view of this, the present invention provides a roll gap adjustment device, which has smaller clearance and higher precision than the existing g...
