摘要： PURPOSE:To obtain a rolling mill capable of performing both a rolling with movable work rolls and a rolling with fixed rolls by constituting said mill that supports attachably and detachably the roll chocks of work rolls by side beams installed movably by a driving means in the axial direction of the roll. CONSTITUTION:Roll chocks 3a, b, 3'a, b of work rolls 2, 2' are supported by side beams 11a, b, 11'a, b provided, movably on respective projecting guides (not shown in the figure) and in the axial direction of the roll, to the housings 1a, 1b placed at the operating side A and the driving side B of a mill, and are attachably and detachably engaged with the side beams 11a, b, 11'a, b by clamps 16, 16', 24, 24'. Said side beams 11a, 11'a, are moved by a driving means consisting of worm jacks 19, 19' and screw shafts 20, 20' to shift the work rolls 2, 2' together with the roll chocks 3a, 3'a. Further, supporting beds 29, 29' for supporting the couplings 35, 35', which connect the rolls 2, 2' to spindles 40, 40' in accordance with the length of roll, and the side beams 11b, 11'b are relatively movably connected to each other.

摘要： PURPOSE:To facilitate resetting work of rollers by installing a work roll shift mechanism and transferring upper and lower work rolls to a limit of stroke, and then performing resetting and zero-adjusting work. CONSTITUTION:Upper and lower roll chocks 2a, 2a' are arranged freely movably in vertical and horizontal directions on an internal window of work side housing 1a. Shafts of work rolls 3a, 3b are supported within the chocks 2a, 2a'. A bracket 5 is fixed to the housing 1a by bolts, and a cylinder 8 is arranged on the upper end face of the bracket 5 at a right angle to the rolling line. When the cylinder 8 is moved to Z direction, a lever 12 rotates with a center axis 11 as a fulcrum and move rolls 3a, 3b in the shaft direction X. In the case of resetting rolls, by transferring the rolls 3a, 3b to the limiting positions of strokes, the resetting and zero-adjusting works may be performed simply. Thus, the resetting work is simplified.

摘要： PURPOSE:To improve workability by providing a function by which upper and lower work rolls can be moved axially and a function to control the shape of a rolling mill to said mill. CONSTITUTION:Outside bearing boxes 2, 2' and inside bearing boxes 3, 3' are mounted freely rotatably at both shaft parts of a pair of upper and lower work rolls 1, 1' and the inside bearing boxes 3, 3' on a driving side (a) of a rolling mill are connected via shift bars 4, 4' to driving devices 5, 5' of a jack type. The bearing boxes 3, 3' and the rolls 1, 1' are made integrally movable in the axial direction of the rolls by the devices 5. The boxes 3, 3' restrain the movement of the works 1, 1' in the axial direction of the rolls. Chock supporting beams 7, 8, 7', 8' project in the axial center position on the outside of the boxes 3, 3' and are freely rotatably engaged with a pair of pins 10, 10'.

摘要： PURPOSE:To increase the possible quantity of roll shifting allowing the retreat of a pusher bar while a latch is held open. CONSTITUTION:A latch opening and closing lever 27 tilts vertically around a fulcrum shaft 28 when a lever driving cylinder 31 is driven to extend or contract. The latch 14 turns and attains the open state in which said latch is disconnected from the latch 15 of a roll assembly when the cylinder 31 is driven to extend. A claw part 24 of the latch 14 slides on the top surface of the lever 27 when a pusher bar 11 is retreated in this state in an arrow X direction. The latch 14 retreats therefore while maintaining the open state. The possible quantity of the roll shifting can be thereby increased.

摘要： PURPOSE:To prevent the clogging of grinding bodies and the chipping in corner parts and to improve the efficiency of a grinding operation by detaining the grinding bodies to prevent the rotation thereof when the grinding bodies are pressed to a roll surface and releasing the detention and rotating the grinding bodies at a prescribed pitch when said bodies are detached from the roll surface. CONSTITUTION:The grinding bodies 3 disposed in a plurality are made into a circular cylindrical shape and are supported pivotally by a grinding body holder 4 in such a manner that the axial line thereof is made parallel with the axial line of the roll R of a rolling mill and that the grinding bodies an rotate only in the same direction as the rotating direction of the roll R. An intermittent feed mechanism 15 which rotates the bodies 3 at the prescribed pitch by using a cam plate 15a operating cooperatively with a pressing mechanism 12, a locking mechanism 14 which has braking elements 14a to prevent the rotation of the bodies 3 and a pressing mechanism 12 which presses the bodies 3 by the elements 14a so as to press the grinding bodies 3 to the roll R surface are provided to the grinding body holder 4.

摘要： PURPOSE:To obtain a titled device capable of sliding work rolls with the aid of a small-sized mechanism by slanting an intermediate lever connected freely rotatably to spindles for driving spline-fitted upper and lower work rolls at a central fulcrum and enabling also the fulcrum to shift. CONSTITUTION:Driving spindles 8, 8' are telescopically fitted to spindles 6, 6'. Bearing boxes 11, 11' fitted to spindle shafts freely rotatably are connected to each other by a link mechanism 10-15, and work rolls 1, 1' are slid by slanting an intermediate lever 12 around its fulcrum 21. Further, the fulcrum 21 can be shifted by a hydraulic cylinder 17. In this way, the shafts of work rolls can be slid during operation by a small-sized mechanism.
