摘要： An integrated transverse rolling mill for rolling seamless tubes with skewed axes comprising a piercing stand (2) with skewed axis rolling rolls for piercing a first tube (7) having a first length which is shorter than the space which separates it from the subsequent finishing stand (3) in cooperation with the stake (6), which has the first piercing tip (20) at its end and the second finishing tip (21 ) at the finishing stand (3). The finishing stand (3) is arranged downstream of the piercing stand (2) so that during the rolling operations the front end of the first tube (7) may only be gripped by the finishing stand (3) once the rear end of the first tube (7) is no longer gripped by the rolling stand (2).

摘要： A drive shaft (5) for transmitting motion to a roll (1) of a tube rolling stand comprising a telescopic body (51), a slide (50) and a support base (53). The telescopic body (51) is fixed by one end with a cardan joint (56) to the drive shaft of the gearbox, and on the other end has a fitting (12) for attaching the roll (1). The slide (50) is hinged to the support base (53) and may rotate under the bias of a jack (57) to either engage or release the telescopic body (51). A snap-action locking device (61), contained within the telescopic body (51), comprises a cylinder (64), on which two rocker arms (62', 62") are hinged, and a spring (63) which spreads the rocker arms (62', 62") making the two teeth fit into two holes in the wall of the cylinder (54), when the drive shaft (5) is at its maximum working length. The carriage has two pistons (66', 66") to work on the two rocker arms (62', 62") thus freeing the locking device (61) and allowing the telescopic sliding of the cylinder (55) in the cylinder (54) and the downward rotation of the drive shaft (5).

摘要： The invention relates to a rolling mill for tubes, in which a series of roll-holder containers (10) is housed in an external structure (2) extended along a rolling axis (L); the containers can slide inside the structure to be extracted therefrom and each one houses at least three rolls (17, 18, 19) controlled by respective driving motors (41 , 42, 43). In accordance with the intervention the rolls (17, 18, 19) can be moved inside the containers (10) in a guided way along directions radial in relation to the rolling axis, in order to regulate the distance therefrom.

摘要： A roll-holder cartridge for a three-tube rolling stand with means adapted to release a tube during rolling in case of emergency. The roll-holder cartridge (3) has on both side walls a substantially Y-shaped opening (10) laying with the foot at the vertical axis yoke support so as to be able to pull out the roll-holder cartridge according to a direction coinciding with the horizontal axis of the vertical axis yoke while leaving the support hanging from the fixed structure (13) of the rolling stand. In case of normal maintenance operation, the cartridge (3) is pulled out sideways from the structure of the rolling mill with the yoke support of the vertical axis roll anchored to the cartridge itself, like the other supports of the rolls.

摘要： In order to facilitate side extraction of the roller holder cartridge (3) in a rolling mill stand (100), the strokes of the hydraulic capsules needed to take the pistons of the same clear from the trajectory traveled by the roller holder cartridge (3) during the extraction of the same from the rolling mill, may reach values indicatively between 150 and 400 mm, values which can negatively affect response times of the position control system of said capsules (4"). In order to continue to apply the same capsule control methods but with a considerably more dynamic system capable of rapidly and accurately reacting to sudden changes of pressure, the servo valves in the control circuits are of the four-way type, instead of the three-way type.
