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： 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： The present invention relates to a multi-stand rolling mill (1) for tubular bodies. The rolling mill comprises a first section (10) for rolling on mandrel defined by a first plurality of rolling stands (15′, 15, 15″) arranged in sequence along a rolling axis (100). According to the invention, the rolling mill also comprises a second rolling section without mandrel, arranged down-stream of said first section, which comprises a second plurality of stands (25′, 25, 26, 27, 26′, 27′) arranged in sequence along said rolling axis (100). Each stand (25′, 25, 26, 27, 26′, 27′) of said second section (20) comprises three rollers having rotation axes which are arranged at 120° from one another. The rotation axes for each stand (25′, 25, 26, 27, 26′, 27′) are rotated by 180° with respect to corresponding rotation axes of an adjacent stand. According to the invention, at least one stand of said second section (20) comprises a motorized roller having a vertical rotation axis.
