    摘要: The invention relates to a mill for rolling pipes or other bodies such as flat blooms, bars, rods and the like. The rolling mill is formed by an outer load-bearing structure in which holders are accommodated so as to be extractable therefrom; in the holders there are mounted lever arms (18, 19, 20) that are pivotable transversely to the rolling axis along which the pipes or bodies to be rolled advance. The arms support the working rolls (48, 49, 50) at one end and, at the other end, are secured to the respective holder by means of a pin (22, 23, 24). In the rolling mill of the invention, there are advantageously means for rotating the olders about the rolling axis; this enables the rolls (48-50) to be brought back to the ideal working condition when their dimensions are reduced as a result of periodic machining to which they are subjected for maintenance and their working attitude can no longer be reestablished solely by the swinging movement of the lever arms (18-20) that support them.

    摘要: The inventive relates to a rolling unit (5) for rolling rod-shaped or tubular bodies, such as pipes, hollow sections bars, wires etc. The unit (5) is provided with three or more working rolls (20) which have respective rotation axes (A1, A2, A3) lying in a perpendicular plane to a rolling axis (L) along which the unit (5) is disposed. Advantageously, the rolls (20) are mounted on corresponding swinging arms arranged to oscillate in respective planes, perpendicular to the rotation axes (A1, A2, A3) of the corresponding rolls (20) and containing the rolling axis (L). Such a rolling unit can prevent any uncontrolled thermal expansions induced in the swinging arm by the high temperatures sometimes involved in the process, by keeping the rolls in a symmetrical position with respect to the plane of oscillation of the respective arm.

    摘要: A rolling mill for rolling pipes on a mandrel (40) is formed by an alignment of rolling units according to the invention, each rolling unit comprises an outer annular structure (2) formed by at least two plate-shaped elements (3) connected rigidly to one another and housing a roll carrier (10) on which the rolling units (27,28,29), supported by respective pivoting lever arms (19,20,21), are disposed. Each roll carrier (10) can be removed transversely from its rolling unit which, for this purpose, is provided with guides (15) in addition to a loading-unloading device (50) on which the removed carrier is placed. The outer annular structure (2) enables the rolling unit and the corresponding rolling mill better to withstand the radial stresses produced during working, the replacement of the rolls of the respective carriers (10) at the same time being simplified by virtue of their lateral movement.

    摘要: An apparatus is described for adjusting the position of rolls (9) in stands with two working rolls for longitudinal rolling mills, in particular for rolling seamless tubes, with hydraulic capsule directly connected to the chock (8) of each roll bearing, wherein said capsule comprises a movable piston (2) and stationary parts (1, 3). At one end of said piston (2) there is provided a shaped axial element (12) for the engagement into a corresponding undercut groove (18) of said chock (8) to balance the own weights and take up the end plays along the capsule axis. Such an apparatus is preferably associated with a device for detecting the relative position between piston (2) and stationary parts (1, 3) by means of a transducer (7) in an out-of-center position with respect to the axis.
