Definitions

  • the invention relates to a canter for turning rolled material with a gripper-equipped edging head which is rotatable about an edging axis determined by the gripping device which grips the rolling stock and which is supported on a lifting device of a cross slide which can be moved transversely to the edging axis.
  • Canters are manipulators inserted in front of and / or behind rolling stands, in particular reversing stands, which capture the rolling stock emerging from the rolling stand, for example a rolling rod or billet, brake it, rotate it by a certain angle around the rolling stock axis, reserve it laterally for the next rolling pass move and bring the respective inlet stirrers.
  • the canters have angularly adjustable cantilever heads supported by a lifting device on a cross slide, which as grippers are usually equipped with a pair of pinch rollers which have pinch rollers which can be driven in both directions and are adjustable for gripping or releasing the rolling stock .
  • the gripper that grips the rolling stock also determines the edge axis, that is to say the axis around which the rolling stock is folded by the edge head.
  • the square heads are therefore also around this cantilever axis rotatably mounted on the lifting device, for which it is very expensive and space-consuming support structures made of interlocking, oppositely adjustable pairs of pivot levers u.
  • the lifting devices and cross slides receiving these support structures also allow the entire cantilever head to be lowered below the rolling axis and the cantilever head to be submerged under the rolling stock, or the cantilever head to be laterally displaced from the caliber to the caliber.
  • a pliers cantilever has already been proposed, the pliers of which are mounted on a cross slide so as to be pivotable about 90 ° about an axis of rotation lying below the roller table plane, the cross slide being connected to the pliers actuator via a toothed segment pinion gear and simultaneously executes a transverse movement with the swiveling movement of the pliers to compensate for the swiveling transverse offset of the rolling stock axis.
  • These tongs can therefore not edge the rolling stock around the longitudinal axis of the rolling stock and the transverse movement to compensate for transverse displacement can only be adapted to different rolling stock dimensions by exchanging the toothed segment pinion gear, which greatly limits the possible uses of these canters.
  • the invention is therefore based on the object to remedy these deficiencies and to create a canter of the type described which, due to its relatively inexpensive construction, allows extensive freedom of movement distinguishes its square head and thus its large area of application as well as its compactness and functional reliability.
  • the invention solves this problem in that the edging head is rotatably mounted about an edging head axis parallel to the edging axis, in that the edging head, the lifting device and the cross slide have their own drives and in that these drives are numerically controlled in terms of a composition of the respective edging movement from rotary , Lifting and transverse movement components can be controlled.
  • the edging head By breaking down the edging movement into individual movement components, the edging head itself no longer needs to perform the rotary movement about the edging axis alone and relative to the lifting device or to the cross slide, but can perform these rotary movements in combination with the movements of the lifting device and the cross slide.
  • the required edging movements can be carried out in a rational manner and even in addition to the usual edging movements, such as swiveling of the square head around the Understand the edge axis and the lifting and lowering of the edge head as well as the lateral movement, still special edge movements, for example elliptical or any radially directed movements. Since there is no longer any need for a complicated edging head support and edging head as well as lifting device and cross slide are used equally well, the design is relatively low-cost with a simple, easy-to-understand structure and despite its functionality, a particularly robust and compact edging is produced.
  • the respective actual positions of the square head, lifting device and cross slide can be read into the control device via displacement sensors, in particular angular step sensors, not only is a corresponding movement control achieved, but it is also possible to control the drives as it were, one of the actual positions, preferably the actual position of the square head, to be used as a master value for the control of the other drives, which allows various programming of the control device.
  • the lifting device could in itself be of any design, for example a support frame articulated on swivel arms, a lifting platform or the like supported on scissor levers could be provided, but it is particularly favorable if the lifting device consists of a high slide that can be moved in straight guides of the cross slide, since the guides of the high slide and the cross slide provide simple coordinate directions for component decomposition of the edge movements.
  • Raised sledges and cross sledges work together in the manner of a cross slide, which allows the most direct approach to any point in the plane spanned by the guides within the sled range.
  • a roller edging 1 has an edging head 2 which is equipped with two clamping rollers 3 for gripping the rolling stock to be edged.
  • the pinch rollers 3 are seated on pivoting arms 4 which can move in opposite directions to open and close the pair of pinch rollers and can be driven reversibly by means of a hydraulic motor 5.
  • the square head 2 is rotatable about a square head axis II parallel to the square axis I determined by the pair of rollers 3 on a high slide 6 and can be rotated at least 180 ° by means of a swivel motor 7 and a corresponding gear 8.
  • the high slide 6 is displaceably guided in straight guides 9 of a cross slide 10 which can be moved transversely to the edge axis I, a lifting drive 11 provided as a hydraulic cylinder ensuring the lifting movement.
  • the cross slide 10 is seated on rollers 12 in horizontal guides of a guide frame 13 and can be moved transversely to the edge axis I via a slide drive 14 which is also designed as a hydraulic cylinder.
  • a numerical control device 15 which is only indicated, is connected to the drives 7, 11, 14 of the square head 2, high slide 6 and cross slide 10 via corresponding control lines and, by means of a suitable computer program, allows the edge movements to be carried out by the pinch rollers 3 with respect to the edge axis I into three movement components , which correspond to a rotary movement around the square head axis II, a lifting movement along the straight guide 9 and a transverse movement along the guide frame 13, so that to carry out the respective edging movement, the drives 7, 11, 14 can be controlled via the control device 15 in accordance with these movement components and the edging movement of the clamping rollers 3 to be carried out is exactly reproduced by the mutual superimposition of these components.
  • An angle step encoder 16 is provided on the swivel motor 7 for detecting the actual position of the square head 2 and there are angle step transmitters 17, 18 for detecting the actual positions of the high slide 6 and cross slide 10, which are coupled to the slide movements via rack drives or cable connections 19, 20 or the like . These actual positions are read into the control device 15 via corresponding encoder lines, so that the controls of the drives 7, 11, 14 of the square head 2, high slide 6 and cross slide 10 can be exactly coordinated and also controlled.
  • movable cover carriages 22 are connected via actuators 21 parallel to the cross slide 10 in order to be able to cover the canter region with the square head lowered towards the rolling stock or the rolling stock guide.
  • the edging movements to be carried out by a canter 1 can be assembled component by component by individual control of the individual drives of the edging head 2, high slide 6 and cross slide 10, which results in a simple and robust construction of the canter 1 and brings with it a particularly efficient edging operation.
  • the canter 1 is shown in the usual gripping position, the cantilever head 2 being rotated clockwise 90 to the side of the rolling stock W from a central position with the clamping rollers 3 pointing upwards.
  • the clamping rollers 3, which are now directed laterally to the edge axis I, are open, the rolling stock W can run in between the rollers and is caught by closing the clamping rollers 3.
  • the square head 2 is in the central position and the high slide 6 is completely lowered, so that there is a plunging position in which, with the cover slide 22 closed, the square head 2 with its clamping rollers 3 could dip under the rolling stock, thereby detecting the rolling stock W from two opposite sides would be possible.
  • the range of motion of the canter 1 is not limited to the positions shown in FIGS. 3-6, but it is each one of the corresponding components of movement of the circular movement of the square head around the square head axis II, the lifting movement of the up carriage 6 along the straight guide 9 and the transverse movement of the cross slide 10 Movement that can be assembled along the guide frame 13 is easy to understand.
