Definitions

  • the invention relates to a chain drawing machine for the continuous drawing of particular rod and tubular drawn material according to the preamble of claim 1, in particular a chain drawing machine with at least two, a common pull track assigned drive chains, each having interconnected tension members and the laterally provided by the tension members means drivable are, wherein the tension members are provided on one side with a pressable to the pulling material clamping jaw and on another side with a sliding surface with which the tension members are supported by rotating, load-bearing idler rollers on a rigid roller guide associated with each drive chain.
  • the EP 0 548 723 B2 shows a generic chain drawing machine.
  • the tension members of the drive chains have on their back, ie the side facing away from the jaws on a sliding surface, which runs like a rolling bearing on a mitbewegte, guided on a fixed, rigid roller guide chain of idler rollers.
  • the clamping force is transmitted by means of the idler rollers directly from the jaws on the sliding surfaces on the roller guide.
  • the idler rollers are centered, with all the sliding surfaces of the tension members arranged in series a single, the rigid roller guide opposite and the same width as the idler rollers and the roller guide width extending sliding surface.
  • the individual tension members are connected to each other via bolts and have a complicated arrangement of other follower rollers and locking plates whose geometrical dimensions are coordinated.
  • the object of the invention is to provide an improved chain drawing machine, which is simple and allows high clamping forces.
  • the idler rollers interact with the sliding surface and / or the roller guide via a shared contact surface and are guided at the height of the contact surface division only by guides which follow the rollers.
  • a complex guide device on the sliding surface and / or the roller guide need not be provided, which significantly reduces the cost of the frame.
  • a maintenance of the machine is easier because a fixed guide or with the trailing members follower guide is very difficult to access.
  • roller guides for the drive chains are divided by means of at least one relief recess in guideways in a first alternative.
  • the relief recess may extend substantially along the pull section. Since the roller guides, on which the idler rollers roll, are subject to tolerances and in particular are never completely flat, the idler rollers can adapt better to the roller guide due to the relief recess, so that the effective load-bearing force line increases.
  • the sliding surface of the tension members is divided by means of at least one relief recess in slideways.
  • the idler rollers themselves are designed so that they are slightly articulated, based on the total width of all guideways and slideways, so that they can adapt to existing tolerances in the guideways and slideways.
  • the follower rollers extend over at least two guideways, preferably so that in each case a follower roller extends over all guideways.
  • the idler rollers particularly advantageously have a circumferential taper assigned to each relief recess.
  • the follower rollers experience deliberate weakening or minimizing of their diameter, so that over the width of the idler rollers a resilient adaptation or elastic bending to compensate for the tolerances within the guideways and sliding surfaces can take place.
  • the idler rollers consist of parallel guided roller sets, wherein each guideway and / or slideway is associated with a roller set.
  • the mechanical effort for the leadership of the idler rollers or roller sets is reduced when the roller sets are then connected to each other via roller cages, especially when the roller sets are designed as chains.
  • the guideways and slideways should be uniform and / or opposite each other with the same width. Furthermore, it is advantageous if at least one relief recess divides the roller guide and / or the sliding surface in the middle. In a particularly preferred embodiment, two guideways and / or two slideways are provided.
  • the tension members may be connected by means of a connecting bolt, on both sides of the tension members on the connecting pin rollers and / or pull pieces are arranged.
  • a uniform application of force and force distribution is favored when the jaws and the sliding surfaces are arranged on opposite, mutually parallel sides of the tension members, wherein the clamping jaws and the sliding surfaces or slideways can be integrally integrated into the tension members.
  • the follower rollers are formed at least from two sub-rollers, which are mounted on a common axis.
  • This arrangement is particularly inexpensive, since it can be realized with standard components and still shows the same advantages as the arrangements described above.
  • a spacer for example a sleeve arranged on the axis, is provided between the partial rollers.
  • the follower rollers are connected together to form a chain. Since the tabs of the chain partially overlap, a bending of the chain in the lateral direction is limited. This results in a simple way an external guide of the idler rollers or sub-rollers. This outer guide can absorb laterally acting executives.
  • inner guide elements can receive laterally acting guiding forces, wherein they run along with the rollers and are arranged at the level of the contact surface division and thereby do not come into effective contact with fixed guide elements in the lateral direction.
  • the fact that the inner guide elements can independently absorb management forces, can be dispensed with internal components, which would have to be executed in the form of fixed guide elements.
  • the laterally acting guiding forces are understood to be forces which have a force component which acts on an orthogonal plane which is imaginary in the longitudinal direction of the guiding surface.
  • the inner guide elements are advantageously arranged parallel to the sliding surface and between the sliding surface and the guide surface.
  • these inner guide elements are also arranged. As a result, can be dispensed with fixed side components for guiding the idler rollers.
  • Fig. 1 shows in principle the drive chain guide a chain drawing machine, not shown substantially.
  • the designated 1 drawn material is clamped between the jaws 2 an endlessly rotating upper drive chain 3 and an endlessly circulating lower drive chain 4.
  • the drive chains 3,4 each consist of a plurality of identical to each other trained tension members 5A, 5B, which are interconnected by means of a connecting pin 6, wherein the jaws 2 on the outer side 5 'of the tension members 5A, 5B, based on the orbit of the drive chains 3.4 , are arranged.
  • nuts 7 the connection of the tension members 5A, 5B is secured.
  • the chain drawing machine spaced from each other, here sprockets, not shown, whose teeth interact, for example, with the connecting pin 6 directly or via pull pieces 5A.
  • sprockets for each drive chain 3,4 two spaced sprockets are provided, between which the drive chains 3,4 through and circulate. In this way, a drive is ensured laterally of the tension members.
  • the drive chains 3, 4 are supported along a drawing path, on which the clamping jaws 2 are pressed against the drawn material 1, via follower rollers 8 on a rigid guide surface designated overall by 9 and arranged on the machine frame 10.
  • the guide surface 9 has centrally a relief recess 11 which divides the guide surface 9 into a first guide track 9A and a second guide track 9B.
  • the continuous follower roller 8 which preferably extends at least over the width of both guideways 9A, 9B or both slides 13A, 13B, a circumferential taper 15 in the form of a Specially adapted groove or the like.
  • the circumferential taper 15 ensures that the follower roller 8 can flex elastically and thus can optimally rest with its remaining sections 8A, 8B on the guideways 9A, 9B and slide tracks 13A, 13B, so that the entire width of the Sections 8A, 8B in the support of the tension members 5A, 5B is available as a support surface.
  • the follower rollers 8 may be single roles in special guides or, as shown, be designed as connected with tabs 16 roller chains. Since the tabs 16 mutually partially overlap in the immediate vicinity of the connecting pin 6 and thereby allow only a limited lateral bending of the roller chain, thus the tabs can partially compensate laterally acting executives. The tabs 16 take the task of a direct outer leadership true.
  • the special guides may be formed as inner guide elements 31. These inner guide elements can hereby absorb laterally acting guiding forces and thus hold the follower rollers 8 in the region of the guide tracks 9. As a result, it is possible to dispense with fixed guide elements which are arranged between the sliding surface 13 and the guide surface 9.
  • Fig. 2 An alternative embodiment is shown in half only. Identical components are provided with the same reference numerals.
  • the difference to the embodiment according to Fig. 1 lies in the structure of the follower rollers 18.
  • the follower rollers 18 here consist of two roller sets 18A, 18B, thus divided over the guide surface or sliding surface individual follower rollers; the first roller set 18A is associated with the guide and slide tracks 9A, 13A, the second roller set 18B is associated with the guide and slide tracks 9B, 13B.
  • the roller assemblies 18A, 18B may be interconnected, eg, via roller cages (not shown), and / or the idlers 18 of the respective roller assemblies may be interconnected via tabs 16, as shown.
  • the tabs 16 may represent a direct outer leadership, since the tabs can absorb laterally acting executives.
  • the inner guide elements 31 can receive laterally acting guiding forces, so that fixed guide elements are no longer needed even in this alternative embodiment for a perfect function in the region of the drawing path of the chain drawing machine.
  • two sub-rollers 28A, 28B are provided for the follower rollers 28, which are arranged on an axis 29.
  • a spacer 30 between the sub-rollers 28A, 28B is arranged on the axis 29, which serves to guide the idler rollers 28.
  • the relief recess is dispensed with, and the adaptability or flexibility of the follower rollers is ensured by the spacer 30 between the sub-rollers.
  • the spacer 30 simultaneously constitutes an inner guide element 31.
  • the inner guide elements 31 can receive laterally acting executives. Since also in this embodiment lateral tabs 16 connect the idler rollers with each other, the tabs can also take direct external leadership here.
  • a guide plate 35 is arranged between the inwardly directed follower roller-side surface 32 of the tabs 16 and the opposite side surfaces 33 (lateral surface of the machine frame 10) and 34 (outer side surface of the idler rollers 28) and 36 (lateral surface of the tension members 5).
  • This guide tab 35 is made of a lubricious material and holds the tools in a preferred position.
  • the guide plate 35 slides in its inner upper region on the lateral surface 33 of the machine frame 10 and in its lower inner region on the lateral surface 36 of the tension members 5. At the outer lateral region, the guide plate 35 is partially in contact with the side flap 16 , The guide plates 35 preferably take on no or only very low tensile forces.
  • Fig. 5 is a longitudinal section of a chain drawing machine 38 with an endlessly rotating upper drive chain 3 and an endlessly circulating lower drive chain 4 is shown.
  • the tools or the tension members of the two drive chains 3, 4 converge in such a way that they convey the drawn material 1 in the direction of arrow 40 from left to right through the chain drawing machine 38.
  • a drive chain runs over two sprockets 41 and 42, each one of the sprockets serves as a drive.
  • the teeth of the sprockets 41, 42 engage in the spaces between the connecting pin 6 and thus interact with the connecting pin 6 of the drive chains 3, 4 together.
  • the follower rollers 18 and 28 are arranged. These idler rollers 18, 28 are in rolling contact in particular in the working area 43 with the tension members and the machine frame 10 and transmit the pressure forces arising in the working area 43 onto the machine frame 10.
  • two guide and slide tracks are shown. But it can also be arranged several guide and slide tracks or more relief recesses and the follower rollers are then provided with a corresponding plurality of circumferential tapers or running as multiple roller sets.
