Abstract

The invention discloses a slant wedge locking device for eliminating the clearance of a rotating drum of an oblique rolling machine and the oblique rolling machine. The slant wedge locking device comprises a frame (20), a driving slant wedge (21), a follow-up slant wedge (22) and a hydraulic cylinder (23). When the hydraulic cylinder (23) drives the driving slant wedge (21) to move in the Y-axis direction, the driving slant wedge (21) slides relative to the follow-up slant wedge (22) and moves in the X-axis direction along with the follow-up slant wedge (22). The slant wedge locking device foreliminating the clearance of the rotating drum of the oblique rolling machine is mounted in a rack; the slant wedges are driven by the hydraulic cylinders; the device is used for eliminating the clearance of the rotating drum for adjusting the rolling feeding angle of a roller of a perforating machine or the oblique pipe rolling machine; and the device is simple in structure, steady and reliable.The number of times of replacing a sliding plate or a liner plate can be effectively reduced, and in addition, the service life of the hydraulic cylinder can be improved conveniently; the adjustmentaccuracy and precision of the rolling feeding angle are improved; and rolling quality is further guaranteed.

Description

technical field [0001] The invention relates to the field of rolling equipment, in particular to a wedge locking device used for eliminating gaps in a drum of a skew rolling mill, and also to a skew rolling mill. Background technique [0002] At present, skew rolling mills such as piercing mills and pipe rolling mills generally use drum rotation to adjust the rolling feed angle of the rolls, and the slide plate embedded on the drum slides relative to the liner plate installed on the frame. Such as figure 1 As shown, for a two-roll piercing machine, there are two matching drums, and two sets of lining plates corresponding to the drums, four respectively; the drum 3 equipped with the roll 1 rotates around the center of rotation R, and the surrounding is surrounded by perforation The liner 4 in the frame 5 guides and guards, and the liner 4 is all fixed and non-adjustable; figure 2 As shown, for a skew rolling mill or a three-roll piercing machine with a drum structure, ther...
