Definitions

  • the subject invention relates to a steering wheel driver with two rollers, wherein a first roller is arranged substantially stationary and a second roller against the first roller engageable, and with two pivotable rockers, in which the second roller is mounted, and in which for pivoting the Swinging a pressure medium cylinder is arranged in each case.
  • Steering drivers are typically used in rolling mills where they are placed in front of rolled strip reels to set the strip tension in front of the reel by means of two rolls. Another object of the steering operator is to prevent lateral migrations of the rolled strip before being coiled.
  • a pivotable roller is so driven and employed against a stationary roller, that by the position of this roller relative to the stationary roller, the rolled strip undergoes a desired strip tension and a desired lateral displacement.
  • Such a steering driver goes for example from the EP 192 982 B1 or the DE 26 15 254 A1 showing a driver whose pivotal roller is mounted in a continuous rocker.
  • the storage of this roller is movable by control cylinder, so that the roller can be moved according to their storage.
  • the EP 747 147 B1 shows a steering driver whose pivotal roller is mounted in two rockers, where each a pressure medium cylinder attacks and the wings can be controlled separately.
  • the two wings are rigidly connected to a torsion spring, which forms the axis of rotation of the rockers.
  • the spring constant of the torsion spring in the force control always considered.
  • the spring constant is not exactly known and also changes with the external conditions, such as the ambient temperature, material properties of the spring, etc., so that the scheme has a certain inherent inaccuracy.
  • a steering driver having the features of claim 1. Due to the separate wings, the steering actuator can be very easily built and it It is not necessary to take into account mutual influences of interconnected rockers, which makes the steering driver very simple and, above all, precisely controllable.
  • the rockers are mounted at one of their ends on the frame and is arranged in each case at the other end of the pressure cylinder and arranged between the two ends of the rockers, the bearing of the second roller, as there are, inter alia, favorable leverage.
  • a particularly preferred embodiment is obtained by arranging an axle rotatably mounted on the frame and one of the two wings rigidly connected to this axis, which can be further improved by the second rocker is pivotally connected to the axle.
  • the structural design is simplified because only a single axis is required to support both wings rotatably independently.
  • the reliability of the steering actuator is increased when a Verschwenksch is provided to prevent a rocker is pivoted too far and thereby parts of the steering drive or the rocker, e.g. a bearing or seal could be damaged or destroyed.
  • the bearing of the roller and the bearing of the rocker is arranged in a line, so that no tilting moment is created by the actuating force of the actuator.
  • the steering driver according to the invention is described below with reference to the exemplary, non-limiting FIG. 1 described, which shows such a steering driver in three-dimensional view.
  • the steering driver 1 in Fig. 1 consists essentially of a frame 12, in which a first roller 6 is mounted here in a storage 8 substantially stationary. Stored here means that although the roller can rotate, it has essentially no further degrees of freedom with respect to the frame 12.
  • a second roller 5 is rotatably mounted in a further bearing 7 and is arranged adjustable relative to the first roller 6, so it can be moved relative to the first roller 6.
  • two rockers 2, 3 are provided, which are arranged pivotably about an axis of rotation 13 on the frame.
  • the second roller 5 is rotatably mounted in the bearing 7 and at the free end of the rockers 2, 3 is in each case an actuating device 4, such as here a pressure medium cylinder, preferably a hydraulic cylinder arranged.
  • the rockers 2, 3 are mounted separately and independently movable on the frame 12.
  • rolling bearings such as a roller bearing or spherical roller bearings
  • the second rocker 2 is rotatably arranged on the axis 9 by means of a bearing 11, here again a rolling bearing.
  • the two wings 2, 3 can therefore be moved completely independently of each other.
  • the two wings 2, 3 each in a suitable manner pivoted on its own connected to the frame axis or its own pin, the rocker 2, 3 could be fixed to the axle or the pin or stored on this , or directly to the frame 12 to store.
  • an axis could be rigidly arranged on the frame 12, on which the rockers 2, 3 could be mounted pivotably.
  • the pressure cylinder 4 is fixed here with one end to the wings 2, 3 and with its other end respectively to the frame 12, so that by applying the pressure cylinder 4, the second roller 5 can be pivoted about the rotation axis 13 and moved relative to the first roller 6.
  • the point of application of the pressure cylinder 4, the bearing 7 of the roller 5 in the rocker 2, 3 and the bearing 11 of the rocker 2 on the axis 9 and the rigid connection between rocker 3 and axis 9 is preferably arranged in each case in a line, so no tilting moments are caused in the wings 2, 3 by the forces exerted by the pressure medium cylinder 4 forces.
  • the pressure cylinder 4 could also be attached to a laterally projecting projection of the wings 2, 3.
  • the spring assembly 14, which is arranged in each case between the rockers 2, 3 and the bearing 16 of the spring assembly 14, essentially serves to pull the bearing 7 of the roller 5 upwards so as to eliminate or at least reduce the bearing clearance. This should be avoided impacts on the bearing 7 of the second roller 5 when retracting the belt between the rollers 5, 6.
  • a Verschwenk puzzle 15 may be provided to limit the pivotal movement of the pivotable about the axis 9 rocker 2. This prevents that in case of malfunction a permissible swivel angle, for example, of the bearing or a seal can not be exceeded.
  • the Verschwenkêt 15 can be carried out so that on the axis 9 two stops are provided which specify the limits of the pivoting movement, between which another, connected to the rocker 2 and moving mitbetaineder stop moves.
  • the steering actuator 1 is already well known from the prior art and therefore need not be described in detail.
  • the strip tension and lateral movement can be adjusted by means of the steering driver 1, in which the rockers 2, 3 are pivoted by the pressure cylinder 4 and thus the second roller 5 in a desired manner against the first Roller 6 is turned on.
  • the pressure cylinder 4 are to be controlled accordingly and a corresponding regulation is optionally provided.
