    摘要： A tapered roll stand for making seamless pipe has a stationary frame formed relative to a workpiece-travel direction with a pair of laterally and horizontally oppositely open windows. Respective cover doors carried on the frame are vertically shiftable between respective closed positions covering the respective windows and open positions offset therefrom and exposing the respective windows. A pair of tapered rolls are each shiftable horizontally through a respective one of the windows into a use position inside the frame, lying to a respective horizontal side of the direction, and rotatable about a respective axis forming an acute angle with the direction. A pair of Diescher disks are vertically engageable with a workpiece extending in the direction between the tapered rolls, and respective roll-positioning actuators carried on the doors are couplable with the tapered rolls in the use position for setting positions of the tapered rolls.

    摘要： The invention relates to a method and a forming machine suitable for manufacturing a product having various diameters from a workpiece, such as a metal cylinder or plate, in which the workpiece is clamped down in a clamping device, the workpiece and a first tool are rotated about an axis of rotation relative to each other, the workpiece is deformed by means of said first tool by placing the tool into contact with the workpiece and moving the workpiece and/or the tool in a direction along the axis of rotation. At least a second tool is placed into contact with the workpiece at a position behind the first tool, seen in the working direction, and the workpiece is also deformed by means of said second tool. Thus, parts of the workpiece that have been deformed by the first tool are deformed by one or more subsequent tools practically immediately.

    摘要： A method and device for rolling tube to a smaller diameter, with which at least one area of the outside of the tube is brought into contact with at least one roll rotatable around its axis, whereby this roll and the tube are brought into a relative movement with respect to each other. The contact surface of the roll and tube, considered between two planes spaced in a longitudinal direction of the tube, lies at an angle to the longitudinal axis of the tube.The contact surfaces of the rotatable rolls with the deformed tube follow one or more spaced spirals with conically rolled tube or one or more helical lines with cylindrical rolled tube. The position of the effective roll surfaces is adjustable with respect to the longitudinal axis and the transverse axis of the tube, and the contact area with the one or more rolls is heated to the roll temperature before the rolling.

    摘要： The apparatus for changing the rolls (6) of a skew rolling mill comprises a roll-change carriage (14) movable along the direction of feed of material (10) being rolled. A carrier (11) is mounted on the carriage (14) and carries a plurality of roll-clamping devices (12). Locking means (19, 20) are provided for interlocking the rotor (2) carrying a plurality of roll heads (5) skew mounted thereon and the carrier (11) in a predetermined axially-aligned, spaced position for removing or replacing rolls by means of the clamping devices. In a preferred embodiment there are two carriers movable in alternate alignment with the rotor (2).
