The purpose of this utility model is: propose a kind of novel rolling mill, further increase mill stiffness, simplify rolling mill structure.
The utility model content Description: the high milling train just of centering type is made up of rail chair, column support type frame, roller assembly, hold-down transmission device and main drive.Wherein roller assembly see accompanying drawing 1 and accompanying drawing 2(wherein Fig. 2 be the A-A cutaway view of Fig. 1): 1---bearing, 2---the integrated shaft bearing, 3---worm screw, 4---worm gear, 5---eccentric bushing, 6---gear, 7---roll.Be the non-transmission side of roll shown in the accompanying drawing, its transmission side is except that roll mandrel header structure difference, and is symmetrical fully with non-transmission side.
Roller assembly: roller assembly of the present utility model had in fact both comprised lower roll system, had also comprised roll-separating mechanism, and the bearing of each roll the same side is installed in the same integrated shaft bearing 2.Between roll bearing and integrated shaft bearing bore hole, eccentric bushing 5 is set, worm gear 4 and gear 6 are housed on the eccentric bushing 5.The roll gap adjusting device that the centering type symmetry is adjusted is realized roll gap adjustment by symmetrical rotating eccentricity cover, and the rotation of the symmetry of eccentric bushing 5 is to be driven by worm gear or equivalent slew gear.Tie up to roll number, diameter and turn to the different requirements of aspect according to dual roll type, three-roller type or four-high mill roller, eccentric rotating mechanism can be arranged on topping roll, central roll or the bottom roll.In the roller assembly of duo mill shown in the accompanying drawing, worm screw 3 is meshed with worm gear 4, worm gear 4 drives eccentric bushings 5 and rotates, and eccentric bushing 5 driven gears 6 rotate, and gear 6 is meshed with gear on the lower roll eccentric bushing, drives the rotation of lower roll eccentric bushing.Therefore, the worm screw 3 by independent driving one side or drive the worm screw 3 of both sides simultaneously, can realize one-sided symmetry adjust roll gap or both sides synchronously symmetry adjust roll gap.The worm screw 3 of both sides is driven by a gearbox.Because existing one-level speed change between worm gear 4 and the worm screw 3 so above-mentioned this gearbox designs is very simple, but will be provided with a cover gearshift, adjusts synchronously so that realize the one-sided adjustment or the both sides of roll gap.
Column support type frame: all have dovetail (seeing the left side of A-A section in the accompanying drawing) to match on the integrated shaft bearing 2 of the left and right sides with dovetail groove on the column support type frame, also be provided with the adjustment pressing plate therebetween, be used for left, right, front and rear to adjust the horizontal level of roller assembly.The column support type frame lower also is provided with the spiral lifting mechanism of vertical adjustment roller assembly height.Therefore the column support type frame can be adjusted, locate and lock at three degree coordinate direction breaker roll assemblies, and can change roller assembly by quick integral.
Below the column support type frame of and arranged on left and right sides is placed in and on the basic joining milling train rail chair.
Advantage of the present utility model is to simplify rolling mill structure and increases mill stiffness two aspects:
1. simplify the rolling mill structure aspect:
(1), makes roll-force have balance of one's own, thereby can cancel the memorial archway open frame and replace the pillar that only bears gravity in bearing block inside owing to adopted the integrated shaft bearing; And can realize the new technology of integral replacing roller assembly;
(2), thereby cancelled housing screw nut type screw-down because employing rotating eccentricity cover is realized the symmetry adjustment of roll gap;
(3) owing to adopt the integrated shaft bearing and cancelled the housing screw nut, matching surface is all adopted in roller assembly inside, does not have free clearance, thereby has cancelled the top roll bascule;
2. increase the mill stiffness aspect:
Owing to cancelled two key factors that influence mill stiffness on the old-fashioned milling train: the elongated tension and compression members that are subjected to such as housing post and housing screw, and adopted the bigger integrated shaft bearing of rigidity, so obviously improved mill stiffness.
The enforcement of utility model: the centering type stiff mill can be (the seeing accompanying drawing) of dual roll type: if below lower roll, install again one with the duplicate mechanism of top roll, can constitute three-roller type; If by the size of the diameter of backing roll and working roll configuration eccentric bushing with turn to, increase the roll number, then can constitute four-roller type; Other cluster mills (as long as roll axis is parallel, planetary except) all can adopt structure of the present utility model.
