  • For maintenance or for changing roles are both straightening roller units transverse to the tape running direction by means of a Change device from the machine stand or machine unit on the side pulled out.
  • the chassis at least the upper Straightening roller unit is rotatably arranged on two aligned pivots, which each in two support elements arranged at the two ends of the chassis rotate and thus determine a horizontal axis of rotation around which the Entire upper straightening roller unit between a working position with the down aligned work roll and a twisted maintenance and expansion position with the work roll facing up.
  • the invention has for its object a straightening machine of the generic type Art in such a way that with less equipment and without the rotation of the upper straightening roller unit or the upper one Straightening roller unit in its entirety the roles of the upper straightening roller unit are accessible for their maintenance or removal and installation.
  • a generic straightening machine is developed in such a way that the roller cassette at least the upper straightening roller unit has a bearing unit which takes up at least the straightening roll or the work roll and which on the metal or the outlet side of the roll cassette between one closed position and a pivoted role maintenance and expansion or installation position is pivotally arranged.
  • This solution has the advantage that not the entire straightening roller unit as such must be rotated, but only the claimed roles, i.e. at least the straightening roller into the maintenance position. Because the solution expedient for the upper straightening roller unit is the Storage unit arranged below on the roller cassette. The swivel angle between the closed position with the straightening roller pointing towards the belt and pivoted position is to be chosen so that the role or roles accessible become.
  • the storage unit comprises at least two roller housings for the storage of the respective drive and operator side Reel ends. These roller housings are each attached to a bearing block, the is pivotally arranged on one side of the roller cassette and on its Pivot point opposite side detachable using fasteners - preferably a screw connection - for the closed position the roller cassette can be locked.
  • the front of the roller cassette is i.e. of the sides running parallel to the tape direction, a spring element arranged, which interacts with the respective pedestals and so is dimensioned that the total weight of the roller housing including Roll (s) and the bearing block is approximately balanced.
  • a gas pressure spring is recommended; a liquid spring or mechanical springs are also conceivable. Moves when swiveled the rod head of the gas spring slightly past its dead center, whereby the storage unit secured against kicking back in the maintenance or removal position is held.
  • bearing unit is pivoted manually. Is conceivable but also the use of manipulators that attack the storage unit and make the pivoting movement.
  • the function as a handle is a storage unit along the longitudinal axis of the roller cassette, i.e. transversely to the tape running direction, spanning bracket provided, the connected to both the drive and the operator-side bearing block is.
  • the pivoting movement in the rest position To perform straightening roll units, i.e. inside the machine stand in one position of the straightening roller units spaced from the metal strip. It recommends but above all for safety and handling reasons, the straightening machine to be provided with guide means, d. H. with a changing device for Movement of the two straightening roller units horizontally to the metal belt conveyor level to a maintenance and expansion position adjacent to the machine stand.
  • a system for straightening a metal strip in particular one cold-rolled thin strip - stretch straightening is also conceivable for hot-rolled strip Thin strip - proposed a plurality of such straighteners or a straightening machine with a large number of straightening roller units, for example six, as well as control means for moving the tape run.
  • Figures 1 and 2 show an overview of the longitudinal and cross section of a Straightening machine 4 for straightening metal strip 25.
  • the proposed according to the invention Solution of pivoting the storage unit on the roller cassette is described in more detail in Figures 3 to 6.
  • In the machine stand 5 of the straightening machine 4 are three upper and lower straightening roller units 1 a in each case to 1c, 6a to 6c, each provided with adjusting means 24a to 24f are the individual straightening role units or the straightening roles in the working position to the band 25 move almost vertically and in the desired working position hold.
  • the roller straightening units each consist of a roller cassette 2 or frame, which on their way from the tape 25 or the straightening roll End has guide rollers 3 which run on guide rails 8, around the respective straightening roller unit between a first position in a machine stand and a second maintenance adjacent to the machine stand and to change position (see FIG. 2).
  • the extend Guide rails 8 across the width of the machine stand 5 and above out. In the extended position, only the rear guide rollers are left 7 'contact with the rail 8 while the front end of the roller cassette is over a pin 10a on the extended changing and extending device 10 '(10th in the extended position).
  • the crane shown here (schematic indicated as a hook 9) supports the removal of the roller cassettes from the Exchange device if, for example, the expansion of not within the Roller cassette guided rollers - here the support rollers - is necessary.
  • the proposed according to the invention pivotable Arrangement of the rollers to the roller cassette 2 of an upper straightening roller unit 1 described.
  • the upper one Straightening roller unit 1 extends the stretch straightening rollers.
  • a straightening roller 10 which runs between two intermediate rollers 11a, b, which in turn are supported by three support rollers 12a, b, c (see also FIG. 4).
  • the straightening roll 10 and the two intermediate rollers 11a, b are each end in a roller housing 13 stored.
  • This roller housing 13 is connected to a bearing block 14, which on one side in the pivot point A at the lower part of the front of the Roll cassette is pivotally mounted.
  • the pivot point can either be on the metal strip inlet or outlet side.
  • An opposite side is the bearing block 14 by means of a screw connection 15 releasably locked on the front of the roller cassette. Via a lever element 16 attacks a gas pressure spring 17 on the bearing block 14.
