Definitions

  • the invention relates to a double roller guide for rolling mills, consisting of at least two guide rollers arranged one behind the other in the rolling direction, which are mounted on assigned roller carriers, which are arranged pivotably and adjustable with respect to the feed of the guide rollers.
  • roller guide In various rolling processes, e.g. on open roads and on continuous roads with loop control, the roller guide should also have a certain straightening effect. Therefore, instead of one pair of rollers, two pairs of rollers are combined to form a double roller guide. Double roller guides are known in various embodiments.
  • the guides can be quickly and easily adjusted to adapt them to the changed conditions of the rolling stock when the quality changes.
  • the rollers connected in series are adjusted parallel to one another on one side of the rolling stock. There is no suitable facility for this.
  • the object of the invention is to improve a double roller guide of the type described at the outset so that at least two rollers connected in series in the rolling direction, but with four pairs of rollers arranged on both sides of the rolling stock, all four rollers can be fed centrally and in parallel.
  • roller carriers are each two-armed swivel levers, at one end the guide roller is mounted and the other end is supported on an adjustable stop, the transmission ratios of both roller carriers are the same and the end of a roller carrier on the other roller carrier in Distance from the pivot axis is supported.
  • the roller carriers form a lever gear because the end of one roller carrier is at the same time the adjustable stop for the end of the other roller carrier. It is therefore sufficient to adjust one of the roller carriers so that the other Roller carrier adjusted in the same way and thus both guide rollers are fed in parallel.
  • the respective distances between the axis of rotation of the guide roller-pivot axis of the roller carrier on the one hand and the pivot axis of the roller carrier-adjustable stop on the other hand should be the same for both roller carriers.
  • the result is a kind of parallelogram guidance, but both roller supports are only supported in the area of their swivel axes and are supported on the adjustable stops and on the guide roller on the rolling stock.
  • the distance between the adjustable stops (in the rolling direction) is expediently the same as the distance between the pivot axes (in the rolling direction).
  • the adjustable stop for one roller carrier can be a cam. By turning the cam, the end of the roller carrier supported thereon is pivoted more or less and the associated guide roller of the roller carrier is fed in the opposite direction. The same applies to the other roller carrier, which inevitably follows the movement of the end supported on the cam disc.
  • the axis of rotation of the cam should be arranged orthogonally to the swivel axes of the roller carriers, the cam having at least on one side a support surface with a circumferentially variable distance from the central plane of the cam. If the double roller guide only has two guide rollers on one side of the rolling stock, it is sufficient if the cam disc has a support surface on one side.
  • the cam can also have support surfaces on both sides, which are mirror-symmetrical to each other, so that a roller carrier of a double roller guide with four guide rollers can then be supported on each support surface. Since the support surfaces are mirror-symmetrical, all four guide rollers of a double roller guide are fed in the same direction and in parallel when the cam disc is rotated.
  • a particularly simple embodiment of the invention is characterized in that the support surfaces are flat.
  • the cam disc is then wedge-shaped in cross section. It is easy to edit.
  • a locking device can be provided for the cam. This can be, for example, a clamping screw with which the cam disc is fixed.
  • At least one spring can be provided, which presses the roller carrier against its assigned stops.
  • the supported ends of the roller carriers can have adjusting screws, by means of which they are supported on the assigned stops.
  • the double roller guide shown serves to introduce the rolling stock, not shown, into the roll caliber.
  • the double roller guide is arranged in a housing, not shown, or on a support frame, not shown. Only one half of the double roller guide with two roller carriers 1, 2 is shown. In mirror image to the center line 3 shown, two further roller carriers, not shown, are arranged.
  • Each roller support 1 or 2 is pivotally mounted about a pivot axis 4 or 5 in the housing or on the support frame.
  • a guide roller 6 or 7 is rotatably mounted for the rolling stock.
  • an adjusting screw 8 or 9 is held in an associated threaded bore, which extend orthogonally to the pivot axes 4 and 5.
  • the adjusting screw 8 of the outer roller carrier 1 is supported on an associated stop 10 of the inner roller carrier 2.
  • the adjusting screw 9 of the inner roller carrier 2 is supported on a rotatable cam plate 11, the axis of rotation 12 of which extends orthogonally to the pivot axes 4 and 5.
  • the cam plate 11 has a wedge-shaped cross section, so that flat support on both sides Surfaces 13, 14 are formed, each having the same distances from the central plane 15 of the cam plate 11 in the same coordinates.
  • the roller carrier of the other pair of roller carriers is supported in a corresponding manner and in mirror image on the support surface 14.
  • At least one spring is provided which presses the roller carriers 1, 2 against their associated stops 10 and 13, respectively.
  • the cam disk 11 can have a measuring scale on its outer circumference and, moreover, one or more approaches for a tool for rotating the cam disk 11. So that the cam disc 11 does not twist during operation, a locking device, not shown, is e.g. a clamping screw is provided.
  • the gear ratios of both roller carriers 1, 2 are the same.
  • the distances between the respective axes of rotation of the guide rollers 6 and 7 from the pivot axis 4 and 5 of the associated roller carrier 1 and 2 are the same and the distances between the pivot axes 4 and 5 of the roller carriers 1 and 2 from the adjustable stops 10 . or 11 the same.
  • the distance between the stops 10 and 11 is equal to the distance between the pivot axes 4 and 5.
  • the adjusting screws 8.9 serve to compensate for manufacturing tolerances and also for presetting with regard to the parallelism of the guide rollers 6.7 with regard to the rolling stock.
