Definitions

  • the invention relates to a chain pulling machine for continuous pulling of rod-shaped and tubular drawing material in particular according to the preamble of claim 1, in particular a chain drawing machine with at least two drive chains assigned to a common drawing section, each have interconnected tension members and the side of the Tension members provided means can be driven, the tension members on one side with a clamping jaw that can be pressed onto the drawing material and on one other side are provided with a sliding surface with which the tension members via rotating, load-bearing idler rollers on each drive chain support the assigned rigid roller guide.
  • EP 0 548 723 B2 shows a generic chain pulling machine.
  • the Tension links of the drive chains have on their back, i.e. who the Side facing away from the jaws on a sliding surface that acts like a roller bearing via a moving chain guided on a fixed, rigid roller guide of idler rollers.
  • the clamping force is achieved by means of the idler rollers directly from the clamping jaws over the sliding surfaces to the Transfer role management.
  • the idler rollers are used to counteract and counteract stress arranged in the middle, with all sliding surfaces of the arranged in series Tension members a single, opposite the rigid roller guide over the same width as the idler rollers and the roller guide width have extending sliding surface.
  • the object of the invention is to provide an improved chain pulling machine create that is simple and allows high clamping forces.
  • the idler rollers with the sliding surface and / or the roller guide interact via a divided contact surface and at the level of the contact surface division only by using the rollers guided guides are guided. That way one needs elaborate guide device on the sliding surface and / or the Roller guide can not be provided, which increases the presentation costs reduce significantly. Maintenance of the machine is also easier because a fixed guide or a guide running with the tension members only is very difficult to access.
  • roller guides for the drive chains by means of at least one essentially along the drawing line extending relief recess are divided into guideways. Since the Roller guides on which the idler rollers roll with tolerances are afflicted and in particular are never completely flat, they can Idler rollers better due to the relief recess Adjust the roller guide so that the effective load-bearing line of force increases.
  • the sliding surface of the is also to achieve the same advantages Tension members by means of at least one relief recess in slideways divided. It is particularly preferred if the idler rollers themselves are designed so that, based on the entire width of all Guideways and slideways are slightly flexible, so that they adhere to existing tolerances in the guideways and slideways can adjust.
  • the idler rollers move extend over at least two guideways, preferably thus one idler roller extends over all guideways.
  • the idler rollers each Relief recess associated with circumferential taper.
  • the follower wheels experience, depending on the location of the Relief cutouts, deliberate weakening or minimization of their Diameter, so that a within the width of the idler rollers elastic adjustment or elastic bend to compensate for the tolerances can take place within the guideways and sliding surfaces.
  • the idler rollers are made of parallel roller sets, each guideway and / or Slideway is assigned to a roller set.
  • the mechanical effort for that The guidance of the idler rollers or roller sets is reduced if the Roller sets are then connected to each other via roller cages, especially if the roller sets are designed as chains.
  • the Guideways and slideways uniform and / or with the same width opposite. It is also advantageous if at least one Relief recess, the roller guide and / or the sliding surface in the middle Splits. In a particularly preferred embodiment there are two Guideways and / or two slideways provided.
  • the tension members can be connected by means of a connecting bolt be connected, with the tension members on both sides of the connecting bolt Rollers and / or tension pieces are arranged.
  • An even one Force introduction and force distribution is favored when the jaws and the sliding surfaces on opposite, mutually parallel sides of the Tension members are arranged, the clamping hooks and the sliding surfaces or slideways can be integrated in one piece in the tension members.
  • the idler rollers are formed at least from two sub-roles on a common axis are stored.
  • This arrangement is particularly cost-effective since it is compatible with Standard components can be realized and still have the same advantages as the arrangements previously described.
  • a spacer for example one on the axle arranged sleeve, may be provided.
  • the Idler rollers are connected to a chain. Since the tabs of the Chain overlap partially, is a bending of the chain in the side Direction possible only to a limited extent. This creates in a simple way an outer guide of the idler rollers or the partial rollers. This outer Leadership can take on laterally acting managers.
  • inner guide elements act laterally Executives can take on, where they run with the roles and are arranged at the level of the contact surface division and in the lateral Direction not effectively in contact with fixed guide elements come. Because the inner guide elements are independent Executives can take on internal components, which in In the form of fixed guide elements, to be dispensed with. By eliminating such fixed Among other things, management elements also released space, which in turn for a more compact design is available.
  • Lateral executives are understood to mean forces that have a force component, which in the longitudinal direction to the The guiding surface has a fictitious orthogonal plane.
  • the inner guide elements are advantageously parallel to the Sliding surface and between the sliding surface and the guide surface arranged.
  • Fig. 1 shows in principle the drive chain guide one essentially shown chain pulling machine.
  • the drawn goods with 1 is between the jaws 2 of an endlessly rotating upper drive chain 3 and an endlessly rotating lower drive chain 4 is clamped.
  • the Drive chains 3, 4 each consist of several identical to each other trained tension members 5A, 5B, which by means of a connecting bolt 6 are connected to one another, the clamping jaws 2 on the outside 5 ' the tension members 5A, 5B, based on the orbit of the drive chains 3, 4, are arranged.
  • the tension members 5A, 5B are connected by nuts 7 secured.
  • the chain pulling machine has to drive the drive chains 3, 4 Spaced from each other, not shown here, sprockets, their teeth e.g. with the connecting bolts 6 directly or via tension pieces 5A work together.
  • 3.4 are preferably two for each drive chain spaced sprockets between which the Drive chains 3,4 through and around. In this way it becomes a drive guaranteed laterally of the tension members.
  • the drive chains 3, 4 are supported along a drawing line on which the Clamping jaws 2 are pressed against the drawn material 1 via idler rollers 8 a rigid one, generally designated 9 and on the machine frame 10 arranged guide surface.
  • the guide surface 9 has a center Relief recess 11 that the guide surface 9 in a first Guideway 9A and a second guideway 9B divides.
