  • Patent number: 7299673
    Abstract: Rolling device with two work rolls supported in a rolling stand by a chock and with at least two additional rolls supported in the rolling stand by an additional chock. At least one of the work rolls and at least one of the additional rolls is adjustable for adjusting a desired roll gap relative to the other work roll or relative to the other additional roll. The work rolls have axial shifting devices for axial shifting and holding the work rolls into a desired axial position relative to the rolling stand. The work rolls are operatively connected with bending devices, by which a bending moment can act on the work rolls. The axial shifting devices are arranged and act between the rolling stand and the work roll locking mechanism. The bending devices are arranged or act between the work roll chock and the chock of the additional roll.

  • Publication number: 20070251349
    Abstract: The invention concerns a drive spindle (1) for the main drive of a rolling stand, which has: a first shaft (3) for transmitting torque from a drive motor (2) to a coupling element, especially to a multiple spline profile, and a second shaft (5) for transmitting the torque from the coupling element, especially the multiple spline profile, via a swivel joint (4) to a roll (6) of the rolling stand, wherein the swivel joint (4) has a wobbler (7), which is rotationally rigidly connected with the roll (6), and a second spindle head (8), which is rotationally rigidly connected with the second shaft (5), and wherein the rotational connection between the wobbler (7) and the spindle head (8) is produced by sliding bearings and a journal (9), which is rotationally rigidly connected with the spindle head (8) but is supported in a way that allows an angle of inclination (?) between the axis of rotation (10) of the roll (6) and the axis of rotation (11) of the second shaft (5).

  • Publication number: 20070140781
    Abstract: The invention relates to an overload security coupling, in particular for main drivetrains on rolling stands, forming a bridge between a toothed spindle section (1) and a spindle section (6), with an interference fit. According to the invention, the security coupling for axial overload may be combined with a rotational fixing against torsional overload, whereby the same is embodied with a rotating sliding sleeve (3), housing the spindle section (1) with internal toothing in an axially-displaceable manner at one end and enclosing the spindle section (6) with an inner sleeve (4) in the interference fit at the other end and the rear sleeve-like projection (13) thereof generates a fixed functional connection which gives way in case of overload with a pressure sleeve (5) and a pressure gap (14), tensioned by pressure medium.

  • Publication number: 20070129228
    Abstract: The invention relates to a rolling device (1) comprising at least two working rolls (2, 3) which are respectively mounted in a roll stand (6) by means of working roll assembly pieces (4, 5). At least one of the working rolls (2, 3) is adjustable relative to the other working roll (2, 3) within the roll stand (6), especially in a vertical direction, so as to adjust a desired rolling gap. At east one working roll (2, 3) is effectively connected to bending means (7), with the aid of which said working roll (2, 3) can be impinged upon by a bending moment. The working roll assembly piece (4, 5) is provided with arms (9, 10) that laterally protrude relative to the axis (8) of the working roll (2, 3) to absorb the force generated by the bending means (7).

  • Publication number: 20070107482
    Abstract: The invention relates to a rolling device (1) comprising two working rollers (2) which are respectively mounted in a roll stand (4) by means of working roller inserts (3). The working roller inserts (3) in the roll stand (4) can be locked and unlocked by means of at least one working roller locking device (5). At least two other rollers (6), especially two support rollers are respectively mounted in the roll stand by means of other inserts (7); the position of at least one of the working rollers (2) and at least one of the other rollers (6) in the roll stand (4) can be adjusted, especially in a vertical direction, in relation to the other working roller (2) or other roller (6) in order to adjust the desired rolling gap. The working rollers (2) are provided with means (8) for axial displacement, enabling the working rollers (2) to placed in a desired axial position in relation to the roll frame (4) and maintained in said position.

  • Publication number: 20050254737
    Abstract: Disclosed is a device for influencing in a controlled manner the load-bearing force of supporting rollers (SW) that rest on working rollers. The neck (WZ) of said supporting rollers (SW) which is provided with an extension (ZA) is mounted in roller bearings or sliding bearings that are disposed in a bearing-supporting housing of the rollers of a roller stand. The neck extension (ZA) is mounted in a supporting bearing. The outside of the housing (LG) of said supporting bearing is connected to the bearing-supporting housing. An intermediate housing (ZG) which is inserted in the housing (LG) of the supporting bearing cylindrically encloses the supporting bearing, is impinged upon by a piston cylinder unit (RB, SK), and can be displaced within said housing (LG) in a radial direction relative to the axis of the neck extension (ZA).

  • Patent number: 6959805
    Abstract: A guide device on a vertical roll rolling mill frame (WG) which has vertical guide plates (FP) for the rolled product on both sides of the vertical roll pair (VW) above the rollers (RR) of the roller conveyor for feeding the rolled product 2 and removing the rolled product from the roll and on a carrier (TR) for each vertical guide plate (FP), shiftable transversely to the rolling direction, adjustable and lockable. The carrier (TR) of each guide plate (FP) is connected on its back side with the linear positioning member of a mechanically or hydraulically driven shifting device which is fixed on the bearing body (LK) of the vertical roll. The carrier (TR) is cantilevered slidably above the roller conveyer and parallel to its roller axed in a cantilevered kulisse (FK) which is fixedly connected with the rolling mill frame.
