Definitions

  • a rolling stock guide with horizontal rollers which are rotatably mounted in a roller frame and are arranged one behind the other in the rolling direction is known and can be adjusted in groups to the respective dimensions of the rolling stock.
  • Rolling armatures of this type form an introduction and thus a stabilizing guide device for rod-shaped rolling stock emerging from hot rolling mills, which enters a subsequent rolling mill.
  • the known device has an odd number of mutually opposing stabilizing rollers, which are mounted in a fixed and an opposite pivotable part and also two offset in front of the stabilizing rollers, provided with an inlet funnel.
  • an adjustment fixture In order to adjust the adjustable roller group to a new rolling stock dimension, an adjustment fixture must first be released at one end and only then can the other end of the roller group be pivoted to the new rolling stock dimension.
  • the invention specified in claim 1 addresses the problem of ensuring by guiding the rolling stock in two mutually perpendicular planes and thus centric entry into the rolling mill that no more twisting of the rolling stock can occur in the roll gap and thereby centering the rolling stock in the control system can be integrated.
  • the advantages achieved by the invention consist in particular in that, with appropriate actuation or control of the actuator, twisting of the rolling stock in the roll gap can no longer occur, that the tensile or compressive stress in the rolling stock can be controlled, that this control (or Control) can be used both on the inlet side and on the outlet side.
  • this control or Control
  • the rolling stock guide can be used for both zero-caliber and for zero-mill stands.
  • a possible field of application of the invention is also the rolling of wire and the associated voltage regulation.
  • the invention provides that adjacent vertical rollers on the side surfaces of the rolling stock serve as centering rollers and are each rotatably mounted on an adjusting lever, with a pivot drive acting as an actuator on the adjusting lever.
  • the vertical rollers are not only lateral guidance, but also centering means for introducing the rolling stock, in particular flat material, into a desired width section of the roll gap.
  • a safe, precise and aligned over an extended length of the rolling stock is achieved with automatic adjustment to the respective rolling stock thickness or the respective rolling stock profile in that two mutually assigned roller frames can be adjusted by means of at least two pairs of laterally extending adjusting spindle pairs, the adjusting spindle pairs being among themselves are synchronously connected by means of first gear trains and are connected to a first drive motor in rotary drive connection by means of a second gear train.
  • a separately controllable guide on the sides of the rolling stock, in particular of flat material, is also advantageously achieved in that a vertical third drive train is also assigned to the vertical rollers, that each drive train has a worm gear that both sides can be driven by means of a synchronous shaft via an angular gear and a second drive motor is connected. These vertical rollers can therefore be controlled separately from the roller frame.
  • pairs of roller frames be provided on both the inlet and the outlet side, the roller pairs serving as smoothing rollers on the outlet side.
  • Efforts to automate the rolling process are also advantageously supported in that a force measuring cell is connected between two roller frames in order to detect the tensile or compressive stress of the rolling stock between two successive rolling stands in the rolling line.
  • rollers of a roller frame are provided with a controllable and / or adjustable rotary drive.
  • the rolling stock guide is particularly suitable for flat material, e.g. Strip steel, cast strips and the like. suitable. However, it is also possible to guide profile bars of any profile outline.
  • a roller frame 1 rotatably mounted rollers 2 are arranged one behind the other.
  • the roller frame 1 forms a lower roller frame 1a and an upper roller frame 1b.
  • the rollers 2 of two opposing roller frames 1a, 1b form groups 4 for the rolling stock 3, the roller center distances being selected such that there are no offset rollers and the rollers 2 forming a common tangent with their circumference facing the rolling stock 3.
  • a group 4 can thus be adjusted against the rolling stock 3 by means of an actuator 5, namely synchronously and symmetrically to the rolling stock axis 6.
  • the actuator 5 can also be controlled from an operating panel 7 (FIG. 1).
  • each roller frame 1a or 1b more than two roller pairs 2a are arranged axially and one after the other at predetermined intervals.
  • the lower roller frame 1 a and the upper roller frame 1 b formed are each adjustable in a guide 8 transversely to the rolling stock axis 6 (longitudinal axis in the rolling direction). Two such guides 8 are shown in FIG. These guides 8 are arranged offset to the rolling stock axis 6 (FIG. 4).
  • the actuator 5 moves the two opposite roller frames 1a and 1b towards each other symmetrically to the rolling stock axis 6 or away from one another when opening.
  • roller frames 1a, 1b are either horizontally parallel and / or vertically spaced apart across the width / thickness of the rolling stock 3.
  • a lateral guidance of the rolling stock 3 on side surfaces 12 by abutting vertical rollers 2b serves the purpose of using the rollers 2b as centering rollers.
  • the rollers 2b are each mounted on a swivel lever 13 on which the actuator 5 acts as a swivel drive.
  • the power transmission takes place via gear trains connected in series, whereby two mutually associated roller frames 1a, 1b can be adjusted by means of at least two pairs of adjusting spindles 14 and 15 each running laterally from the rolling stock 3 and among themselves by means of a first gear train 16, in each case a clutch 17 and a second gear train 18 are synchronized with a drive motor 19 as actuator 5 (Fig. 4).
  • the adjusting spindle pairs 14 and 15 are moved on both sides by means of the drive motor 19 against pressure springs 20, the relief of which is associated with opening the two roller frames 1a and 1b.
  • the two roller frames 1a, 1b are guided over the guide 8 by means of guide pins 21 in a ceiling 22a of a guide box 22.
  • the guide box 22 itself is aligned with the rollers 9a and 9b by means of retaining clips 23 and is fixed on a roller fitting carrier 22b in a stationary or displaceable manner parallel to the roller axis.
  • An inlet funnel 22c is also provided on the guide box 22 (FIG. 2).
  • the adjusting spindle pairs 14 and 15 are axially supported by an axial bearing 14a.
  • third drive trains 24 are also assigned to the vertical rollers 2b and, starting from a second drive motor 25, connect both sides by means of a synchronous shaft 26, a third Drive train 24 is assigned a worm gear 27a and 27b (FIG. 3) and a shaft 28a or 28b and an angular gear 29 to which the synchronous shaft 26 is non-positively connected.
  • roller frame pairs 1a and 1b can be used both on the inlet side 10 and on the outlet side 11 of the vertical rollers 9a, 9b.
  • the pairs of rollers 2a then serve on the outlet side 11 as smoothing rollers.
  • a force measuring cell (not shown in more detail) can be connected between two roller frames 1a and 1b in order to detect the tensile or compressive stress of the rolling stock 3 between two successive rolling stands in the rolling line.
  • rollers 2 of a roller frame 1a and 1b or the vertical rollers 2b are provided with a controllable and / or adjustable rotary drive.
