  • Patent number: 10022775
    Abstract: A device and a method for forming hollow cylindrical bodies. The device has a plurality of stations. A tool is allocated to each station. The tools are arranged on a common carrier. The tool can be moved between two reversing positions via a main drive. This reciprocating movement is executed intermittently. One of the two reversing positions forms a rest position in which the tool carrier stops in a rest phase. While the tool carrier stops in a rest position in the rest phase, a transport device transports the bodies from one station to the respective next station.

  • Patent number: 10016797
    Abstract: Rolling unit including at least two adjacent rolling stands, each having a pair of rolling rolls mounted on respective motorized shafts. The rolls of one rolling stand are disposed orthogonal and close to those of the adjacent rolling stand. The shafts are eccentrically supported in respective support elements, which are selectively rotatable around their axis and are each provided with rotation means to cooperate mechanically with an adjustment member suitable to make the support elements selectively rotate to determine an adjustment of the gap between the rolls. The rotation means of one pair of the support elements are directly connected kinematically to each other. The adjustment member is disposed, with respect to the rolling stands, so that the center of its gear lies very close to the line joining the centers of the support elements, so that a substantial part is contained in the bulk defined by the rolling stand.

  • Patent number: 10010921
    Abstract: A method for bending a thin-walled tube to form a small radius bend on the thin-walled tube includes providing a die, lubricating the thin-walled tube, extruding the thin-walled tube, and thrusting elastomer fillers. A die defining a curved cavity enclosed within is provided. The curved cavity is configured to receive the thin walled tube. The thin-walled tube is lubricated using an antifriction coating material applied on an exterior surface of the thin-walled tube for reducing friction between the exterior surface of the thin-walled tube and the curved cavity of the die. The thin-walled tube is extruded into a curved section from an insertion end of the die. The elastomer fillers are thrusted into an inner surface of the thin walled tube via a mandrel. The mandrel is forced against the thin-walled tube to prevent damage of the inner surface of the thin-walled tube to form the small radius bend.

  • Patent number: 9968986
    Abstract: A thread rolling head includes a bearing housing, in which at least two profile rollers, preferably at least three, are each rotatably mounted on an eccentric shaft. A shank is coupled to the housing, and adjacent profile rollers delimit an insertion section into which a workpiece can be longitudinally inserted. The bearing housing includes two housing parts rotatable relative to each other to change the spacing between the profile rollers. An adjustment element interacts with one of the two housing parts and can rotate about the longitudinal axis thereof. Rotation of the adjustment element in a first direction causes rotation of the two housing parts in a third rotational direction, while its rotation in the second direction causes rotation of the housing parts in a fourth rotational direction counter to the third rotational direction. A display apparatus displays a change of the spacing between the profile rollers.
