  • 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: 9314828
    Abstract: In a rolling mill, an open-loop and/or closed-loop control device and a method for adjusting a discharge thickness of rolling stock which passes through a multi-stand mill train, wherein a first section of the rolling stock is rolled to a first discharge thickness, a second section of the rolling stock is rolled to a second discharge thickness which is different from the first discharge thickness. Because a transition from the first discharge thickness to the second discharge thickness takes place at a feed rate of the rolling stock into the mill train which is adjusted as a function of a discharge rate of the rolling stock of a unit which is arranged upstream of the mill train in the direction of mass flow, a method can be made available which runs essentially without reactions for units which are arranged upstream of the mill train in the direction of mass flow.

    Abstract: The invention relates to a method and device for producing metal sections having two profile flanges arranged opposite one another and having flange inner faces that are to be kept apart from each other by a closely toleranced final chamber dimension. In order to adapt the chamber dimension from a starting chamber dimension K0 to a desired final chamber dimension K1, the metal section is passed through the device, which forms working gaps between an inner working roll pair and outer support rolls. The working rolls that form the inner working roll pair roll over each other in order to brace the forming forces exerted on the working roll pair from the flange inner faces against each other.

  • Patent number: 8091397
    Abstract: A roll grooving apparatus has a back-up roller, a grooving roller positioned vertically below the back-up roller, and a linear actuator positioned below the grooving roller. The linear actuator drives the grooving roller linearly toward the backup roller. A drive is coupled to turn the backup roller. A tubular workpiece is mounted with its wall between the two rollers and compressive forces are exerted on the wall as the backup roller rotates, thereby extruding a circular groove in the workpiece.
