Definitions

  • the invention relates to an interchangeable rolling stand for a rolling installation, preferably for rolling cylindrical rolling stock such as rods, seamless tubes and/or wires, which can be moved along a maintenance direction between a working position and a maintenance position.
  • stretch-reducing and/or sizing mills which have several rolling stands arranged one behind the other in the conveying direction of the rolling stock.
  • the roll stands usually have three rolls which are arranged symmetrically around the cylindrical rolling stock at angular intervals of 120°.
  • constructions with fewer or more rolls per roll stand are also known.
  • the WO 2017/068533 A1 describes a rolling mill with a first section, which has several roll stands and is set up for rolling over a mandrel introduced into the tube, and a second section, which has several roll stands and is set up for rolling without a mandrel.
  • the roll stands each have three rolls.
  • Rolling mills for rolling metal rods and wires with a plurality of roll stands arranged on a rolling line are also disclosed, for example, in US Pat DE 38 30 101 A1 which forms the basis for the preamble of claim 1, DE 39 40 736 A1 , DE 100 15 285 A1 such as DE 101 08 418 A1 described.
  • All or some rolling stands of a rolling train can be set up to be exchangeable in order to service them outside of the rolling train.
  • a change in the dimensions to be rolled requires the relevant ones to be moved out Rolling mills from the rolling train or is thereby at least made considerably easier. This applies in particular to the last roll stands, seen in the rolling direction, since these, as “finishing roll stands”, may have to cover a large product range. Frequent changes in dimensions are the rule here.
  • the fact that rolling stands can be replaced means that rolling operations can be maintained while rolling stands outside the rolling train are being prepared for use. In this way, interruptions in the rolling operation are kept to a minimum. According to the one cited above DE 100 15 285 A1 For this purpose, rolling stands are moved out of and into the rolling train via stand-changing carriages.
  • media couplings are prone to wear and failure. Repeatedly mating the contacts or needles on the media couplers can cause contact problems; for example, the needles can bend, dirt and liquids can get caught in the media couplings, and the like. This can directly lead to electrical faults or dropouts during operation.
  • Robust media couplings that are sealed against external influences, especially for hydraulic applications, are large and expensive. The elimination of any flow resistance also requires generous dimensioning.
  • the media couplings are often difficult to access if they are arranged, for example, below the coupling between the gearbox and the changing unit of the roll stand. Due to the separation of the media lines, the roll stands outside the rolling line are also electrically and hydraulically unconnected.
  • the JP 2013-068303 A describes a mounting structure for attaching a cable protector for protecting and guiding a cable to a movable member.
  • An object of the invention is to specify an improved interchangeable rolling stand for a rolling installation, preferably for rolling cylindrical rolling stock such as rods, seamless tubes and/or wires, which overcomes at least one of the technical problems set out above.
  • the interchangeable roll stand according to the invention is part of a rolling mill or is designed for such a mill.
  • the rolling mill is preferably set up for rolling cylindrical rolling stock, such as rods, seamless tubes and/or wires.
  • the roll stand preferably has at least two rolls. The rolls are preferably arranged symmetrically around the cylindrical stock to apply a rolling force to the outer periphery of the stock.
  • the rolling mill preferably has a number of interchangeable roll stands.
  • the rolling stock is transported through the rolling mill along the rolling direction on a route referred to below as the "rolling line".
  • the interchangeable roll stand can be moved between a working position and a maintenance position along at least one direction, which is referred to below as the “maintenance direction”.
  • the working position is accordingly on the rolling line, with the rolling stand being arranged in the working position in such a way that a rolling stock which is transported along the rolling line can be rolled by the rolls of the rolling stand.
  • the maintenance position is outside the rolling line. In the maintenance position can For example, maintenance work is carried out on the roll stand.
  • a change in the dimensions to be rolled for example when the roll stand is to be equipped with rolls of changed caliber cross-sections, requires the relevant roll stand to be moved out of the rolling line or is at least made considerably easier as a result.
  • finishing rolling stands may cover a large product range. Frequent changes in dimensions are the rule here. Because the roll stand can be replaced, rolling operations can be maintained while the roll stand is being prepared outside the rolling line for later use. In this way, interruptions in rolling operations can be kept to a minimum.
  • the roll stand has at least one media line, which transports a medium used for the operation of the roll stand, preferably electricity and/or a fluid.
  • media includes, for example, electricity for powering electric actuators of the roll stand and/or for exchanging sensor signals, fluids, such as oil and/or water, for supplying hydraulic actuators, for lubrication, cooling and the like.
  • the roll stand also has a cable towing device that is set up in such a way that the roll stand can be moved along the maintenance direction by the distance between the working position and the maintenance position without having to separate the media line from the roll stand.
  • the cable towing device allows the roll stand to be transferred from the working position on the rolling line to the maintenance position without the use of media couplings. If the roll stand has a media coupler, the media line can remain connected for maintenance, stand replacement, and the like, thereby improving its durability.
  • the electrical and/or hydraulic contacts are spared, none can Impurities, oil and dirt enter the media coupling, improving mill stand reliability both at start-up and during operation. In this way, potential sources of error are eliminated by the cable towing device.
  • the electrical and/or hydraulic and/or other functions are also available in the maintenance position of the roll stand. This makes it easier, for example, to preheat the roll stand outside the rolling line. Sensors such as rotary encoders, pressure transmitters, thermometers, etc., actuators and other electronic devices of the rolling mill do not have to be disconnected from the mains during maintenance or during changeover, which simplifies their restart.
  • the maintenance direction is preferably perpendicular to the rolling line, as a result of which the rolling stand can be moved in and out of the rolling line in a space-saving manner in a technically simple manner.
  • the rolling line is clearly defined not only by the rolling mill, but also by the structure of the rolling stand itself, in particular by the location of the rolls.
  • terms of the spatial relationship such as “above”, “below”, “horizontal”, etc., are clearly defined by the usual arrangement of a rolling mill and its roll stands.
  • the roll stand is preferably located on a drag plate, for example firmly connected, which can be moved in the horizontal plane at least along the maintenance direction.

  • the rolling stand can also be moved along a changing direction that differs from the maintenance direction, for example perpendicular to it, with the cable towing device being set up in such a way that the rolling stand can be moved along the maintenance direction and the changing direction by the desired distance, without the Having to separate the media line from the roll stand.
  • the ability to move along a second direction, referred to here as "changing direction" enables or simplifies the exchange of roll stands.
  • the cable towing device preferably has a further cable towing system, which is referred to as an "inverted cable towing system".

Potentially unsafe interruptions in the power supply can be prevented by taking into account one or more electrical lines in the cable towing device.
  • the roll stand can be brought into an operating state or kept in such a state by means of a permanent oil supply "offline", i.e. outside the rolling line, for example kept at the right temperature. This means that the roll stand is ready for use more quickly.
