Definitions

  • the present invention relates to a device for pulling and / or guiding elongated goods, such as electrical cables, pipes, ropes and the like, consisting of collets which are moved in the pulling direction by endless chains and are mounted on tensioning carriages and which face one another in pairs transversely to the pulling direction and are mounted in this direction during their movement in the pull-off direction against one another until they come into contact with or away from the material, the tensioning carriages being guided laterally.
  • Devices of the generic type are used for example for the production of thin-walled corrugated metal pipes. This is because they are manufactured, for example, in such a way that a slotted tube is formed from a continuously running thin metal strip in a series of deformation stages, the edges of which are welded together and the smooth tube is then corrugated in a corrugating device. To achieve a flawless weld, it is necessary, in particular when using arc welding, to avoid transmitting the torque exerted by the shaft device to the smooth tube. Twisting the smooth tube results in the migration of the edges of the slotted tube to be welded together out of the welding device.
  • the contact pressure exerted by the collets of the trigger on the circumference of the smooth tube to be removed is dimensioned so that that the pipe to be removed is firmly guided and secured against rotation by the Weller torque, but on the other hand the smooth pipe is not pressed in, which can occur with very thin sheets with a correspondingly high contact pressure of the collets.
  • a known device provides that between the welding device and the corrugating device there is a trigger which secures the welded pipe against rotation and which consists of endless chains and collets attached to them at such intervals, that the tube is gripped by at least one collet.
  • the collets have clamping jaws, which in turn are mounted on so-called clamping carriages.
  • the tensioning carriages are directly attached to the endless chains, so that every component of motion that originates from the chains or their drives can be transmitted to the tensioning carriages and from these to the clamping jaws.
  • a measure known to create some compensation (“Communication cables with welded and corrugated metallic sheaths" by Dr. Carl Andresen and Dimitri R.
  • the fixation of the clamping carriages consists only in the attachment to the endless chains, which is usually not sufficient, however prevent unwanted impacts, for example due to increased speed of the tensioning carriage in the region reversing its direction of movement, from being transmitted to the material passing through. This is particularly problematic in cases where, as in high-frequency cable technology, even slight deformations in the continuous material become electrical Can cause reflections.
  • the invention has for its object to find a way that the circulation of the clamping carriage and thus the circulation of the collets is going on at a constant speed. In this case, interference factors originating from or transmitted by the chain drives or the chains themselves are to be avoided, if appropriate.
  • the lateral guide consists of endless guide rails extending along the entire orbit of the tensioning carriage. The result is that even in the reversal areas a uniform movement of the clamping carriage and with them the clamping jaws is guaranteed.
  • the guide rails have a profile which is U-shaped in cross section.
  • Guide rollers which are arranged on each tensioning carriage on the side facing the respective guide rail, expediently engage in this U-shaped profile. This measure entails a guide secured against tipping or twisting of the tensioning carriage.
  • the guide rail can be arranged as a prefabricated U-profile in a continuous piece on the straight line and divided into individual pieces in the area of the deflection of the endless chains.
  • a further advantageous embodiment of the invention results, however, when the guide rails are formed in several parts, ie the cross section of the guide rail z. B. consists of two L-shaped and attached to the housing of the trigger device individual profiles. This measure makes assembly considerably easier, it also facilitates the production of the guide rails, in particular, however, if, according to a further inventive idea, these Guide rails have special treads for guide rollers engaging in the U-shaped profile.
  • the guide rollers can be arranged on the tensioning carriage so that their axes are parallel to the housing axis and therefore engage in the U-shaped profile of the guide rail in such a way that they are only partially covered by the profile during the movement of the carriage in the withdrawal direction.
  • An advantageous variant provided in the implementation of the invention is that the axes of the guide rollers run parallel to the legs of the U-shaped profile, i. H. that the bilateral legs of the U-shaped profile form treads for the guide rollers.
  • these treads can also be coated, for example plastic-coated, in order to reduce the rolling resistance of the tensioning carriages on or in the guide rails, but at the same time also to ensure, through a certain damping effect, that the material passing through is free of any mechanical impacts to be led.
  • Another measure according to the invention also leads in this direction, which consists in the fact that the guide rails on both sides are the sole supports for the tensioning carriages. This eliminates from the outset that due to the kinematic sequence of movements of the chain links, mechanical shock impulses are exerted on the tensioning carriages. Lengthening of the endless chains during operation no longer has a negative influence on the uniform movement of the tensioning carriages achieved by the invention.
  • the endless chains themselves are freely movable below the associated tension carts.
  • Separate tension elements for example tie rods, are used for the frictional connection between the endless chains causing the movement of the tensioning carriages and the tensioning carriages themselves. which are connected at their ends both to the tensioning wagons and to the respective endless chain and are rotatably or pivotably mounted at these connection points. The result of this is that the tensioning carriages can easily pass through the path predetermined by the endless guide rails.
  • FIGS. 3 and 4 show an overall view of the trigger device according to the invention in two views, FIGS. 3 and 4 details of the invention.
  • the extraction device 1 is used, for example, to pull a tube 2 longitudinally welded from a strip in a welding device, not shown, and to feed a corrugating device, also not shown, when the initially smooth tube 2 is to be transferred to the corrugated state.
  • so-called clamping jaws 3 are used, as shown in FIG. 2, which are mounted on clamping carriages 4, which in turn are moved on the illustrated path by endless chains 5 .
  • the clamping jaws 3a and 3b which are provided with guide jaws in accordance with the size of the tube 2 passing through, also perform movements against one another, always when they are brought towards one another to enclose the tube 2 and, after the connection with the tube is released, are moved away from one another again .
  • the guide rail 6 is designed so that the jaws 3a and 3b are brought together and so that Grip the continuous pipe firmly.
  • Deflection wheels 8 and 9 serve to guide the endless chains, the deflection wheel 9 being driven by the drive 10 by means of an intermediate gear 11.
  • the guide rail 12 which extends along the entire orbit of the tensioning carriage, is used to achieve a movement sequence that is as uniform as possible and to avoid mechanical shocks, which are particularly noticeable on the continuous tube 2 when it is designed as a thin-walled metal tube.
  • This guide rail 12 is fastened to the machine housing 13 and, as can be seen in particular from FIG. 3, is U-shaped in cross section, in the exemplary embodiment this guide rail 12 is also formed in two parts. It consists of the partial rails 12a and 12b.
  • the tensioning carriage 4, which carries clamping jaws 3a and 3b which can be moved transversely to the direction in which the goods pass 2, is carried solely by the guide rails 12.
  • the guide roller 14 protrudes into the guide rail 12, which rolls on the running surfaces 15 and is connected to the tensioning carriage 4 via a bolt connection 16.
  • the guide rail 6 is used to bring the clamping jaws 3a and 3b together
  • the opening wedge 17 is used to separate the closed clamping jaws 3a and 3b, which engages between the pins 18 of the clamping jaws arranged on the underside of the clamping jaws and presses them apart.
  • This opening wedge 17 can be formed in one or more parts, it can advantageously be adapted in its outer dimensions determining the opening path to the continuous tube 2.
  • the opening width of the clamping jaws 3a and 3b that is currently required can be set, dead times due to unused width Opening paths are avoided by the invention.
  • the roller guides 19 and 20 are advantageously adjustable in the clamping jaws 3a and 3b. Compared to the tensioning carriage 4, the endless chain 5 is guided in a freely movable manner below the tensioning carriage.
  • the endless chains 5 serve as tension elements for the tensioning carriages 4 on the predetermined roller conveyor. So that the endless chains can perform this task without the tensioning carriages, as is provided in known arrangements, directly attached to the chains themselves, as shown in FIG. 4, separate tie rods 21 are provided, on the one hand on the tensioning carriage 4 and on the other are rotatably or pivotably mounted on the endless chain 5.
  • the bolt connections 22 and 23 serve this purpose. Also in the area of the idling of the collets, i. H. in the curved part of the endless guideway, the prestressing carriages are thus safely guided and are moved uniformly, and the exact guiding of the prestressing carriages in the intended guideway ensures uniform circulation. This effect enables higher production speeds, as is required, for example, in the production of high-frequency cables with a longitudinally welded tube as the outer conductor.
