Definitions

  • the invention relates to a traction unit for a drawing machine and a method for pulling an object to be drawn, in particular a long metallic object, with a pulling unit, the pulling unit interacting with a pulling tool and the at least one pulling slide with drive means for the Pulling carriage that back and forth in a guide of a machine frame is moved back.
  • Drawing machines are used to pull elongated metallic objects, such as pipes, strands or rods, through a drawing tool. It will be between continuously operating drawing machines, in which the length of the material to be drawn Dimension of the machine can exceed many times, and discontinuously working drawing machines, like drawing benches.
  • An example of a continuously operating straight drawing machine is from the DE-OS 28 52 071 known.
  • These two reciprocating reciprocating Pulling sled pulls the drawn material endlessly in hand-to-hand operation.
  • the drawing slides are each with a two-armed lever connected by means of a common axis seated double cam can be pivoted back and forth in opposite directions.
  • Another well-known drive system such as in the EP 0 371 165 A1 describes a rotating drum with a curved shape webs running on the surface to produce counter-rotating Drawing carriage movements.
  • the invention has for its object a pulling unit and a method for Operate tractors to create the one described above Does not have disadvantages.
  • the drive means for the drawing carriage of the drawing machine include individually controlled or regulated and electrically driven linear motor complexes for an independent movement of the respective slide.
  • the movement sequence of the individual slide much more flexible.
  • linear motors By using of linear motors is the stroke length or the travel of the individual slide no longer restricted or the drawing paths variable.
  • Linear motors can be exactly control and enable fast acceleration and quick braking. Taking advantage of an overall longer stroke, the average The overall pulling speed is higher because the acceleration or Braking distance is proportionately shorter. It is also possible that the respective Sled on the way back and forth with different and adjustable Speeds can be moved. This allows the pulling sled pull it back in faster. Another advantage is that due to the elimination of the drive mechanism underneath the slide the overall height of the drawing machine can be lower overall.
  • a linear motor complex for a carriage preferably comprises a linear motor unit or several linear motor units, such a complex according to a modular design by choosing the number and / or the driving force of the Linear motor units can be put together. Starting from a basic slide, either with no linear motor unit or a lower power unit is provided, a sled will have the desired performance according to the modular design compiled.
  • the primary part or the primary parts are the Linear motor units as movable primary parts on a slide after one Modular design arranged, the secondary part or the secondary parts of the Linear motor units as stationary secondary parts along the machine frame extend as a metallic track or tracks for the sled. The slides are guided along the track by separate guide rails accepted.

  • the secondary parts of the linear motor units are attached to the sled while the primary parts are stationary are attached to the machine frame.
  • the advance of the pipe start necessary for the drawing process is either by a separate pulling carriage, which is either a linear motor drive or, for example, also has a hydraulic drive, or after a particularly preferred embodiment by a combined pull-out Drawing carriages.
  • Such a combined pull-forward and pull slide preferably has two in a row arranged clamping or clamping jaw pairs, the first Pair for grasping the drawbar for the pulling process and the second pair for Gripping the tube itself is used.
  • a pulling unit with only one such slide forms a first basic unit of the proposed pulling units.
  • This pulling unit the pipe is pulled forward and then discontinuously pulled by a single sled by the sled constantly travels a certain short distance back and forth and therefore pipes themselves great length can pull.
  • This basic unit is particularly suitable for production systems with lower capacity taking into account lower investment costs.
  • This traction unit is advantageously further developed in that such Combined pulling and pulling slide with one, two or more others pulling carriage driven according to the invention is assembled.
  • a second basic unit of the pulling unit is made by means of a separate pulling carriage as well as one, two or more drawing slides.
  • This basic unit has the advantage that the separate pulling carriage does not have a pair of double jaws, but only with a pair of jaws to advance the Pipe start must be equipped.
  • Such a pull-up sledge with a pair of Bakken is lighter than a combined sled and allows higher accelerations.
  • Another advantage is that all sledges, i.e. the early and the pure Pulling sled, have only one pair of jaws and therefore a corresponding one Sled model, which reduces the investment costs.
  • the Traction unit more than two slides, with two or more slides at the same time are in pulling engagement with the drawn goods.
  • the function of a slide carriage can also be taken over by a combined pulling and pulling slide.
  • the respective pulling carriage be driven by a Linear motor complex is driven and the movement of each Flexible slide by controlling the respective linear motor complex is adjustable. This allows flexibility and variability that was previously not possible the slide paths and functions of the individual sledges.
  • the sequence of movements during the drawing process controlled by more than two pulling slides so that two or more pulling slides are at the same time pulling the drawing material.
  • At least one pair of pulling slides is in pulling engagement at the same time with the drawn material.
  • each "Pulling in pairs with alternating partner pulling sled" is always pulled with at least a pair of pulling sledges while the sleds are released be moved back. This results in a multiplication of the pulling force.
  • the drawing slide is designed according to the drawing material at the same time acting number. So if a pair of sledges attack at the same time, one kicks Double the pulling force. The same applies to a simultaneous pull attack with three, four, etc. slide.
  • a preferred drawing method with a total of three drawing slides results the following drawing sequence: pull the drawing material with two with the drawing material in Pulling sled engaged, while the third pulling sled with released Intervention against the direction of pull is then moved in Combine with one of the other two pulling sleds as a pair with the Draw material to engage and pull while the other of the two Pulling sled is moved against the pulling direction with disengaged engagement.
