Definitions

  • the invention relates to a feed device according to the preamble of claim 1.
  • Such feed devices are for example from the DE 32 00 840 C2, DE 34 13 786 C2 or AT-PS 335 262 are known.
  • the last-mentioned publication in particular shows that the pressure roller is pivotally mounted on a lever and from a rest position shown in dashed lines to one of the longitudinal wire adjacent working position is pivotally mounted.
  • the pressure roller should ensure that the line wire of the driven roller cannot evade and should in this way transfer the necessary driving forces to ensure.
  • Knurled driven rollers are sometimes used to ensure a safe loading of the line wire, whereby by profiling the driven rollers at the same Pressure force is the transmission of force from the roller to the line wire is improved.
  • the invention has for its object a generic feed device to improve that even when using of wire with very small diameter a more secure Feeding the wires is effected and at the same time a protection of the wire material is ensured.
  • the invention proposes not a single powered one Roller and an impression roller to use but two driven rollers, between which the line wire is guided and is promoted.
  • the transfer of the feed force is therefore from a single roller on two rollers, so that the same Contact pressure a significantly improved traction or power transmission he follows.
  • 1 is a longitudinal wire, which passes from below a driven roller 2 is applied. Above the A second driven roller 3 is arranged along the longitudinal wire 1. Counter rollers 15 ensure that the rollers 2 and 3 are not bend under the load. The second driven roller 3 does not act directly on the longitudinal wire 1, but by means of a pressure roller 4.
  • the pressure roller 4 is in the position shown in FIG. 1 in her working position in which she is on the one hand from the second driven roller 3 is driven itself and on the other hand Line wire 1 abuts and thus also drives it.
  • the lower driven roller 2 is smooth and without knurling trained so that even minimal wire cross sections Line wires do not damage or deform the Can lead longitudinal wires.
  • the pressure roller 4 is smooth and without Profiling trained.
  • the pressure roller 4 is by means of a small swivel arm 5 around one Hinge point 6 is pivotally mounted on a boom 7.
  • the Pressure roller 4 can swing freely around pivot point 6.
  • the boom 7 is pivotally mounted at a pivot point 8 and is at its free, i.e. movable end by a piston-cylinder arrangement 10 acted upon hydraulically or can work pneumatically and on an arm 11 of the Supports the welding machine.
  • the Pressure roller 4 even with progressive wear Pressure roller or with a wide variety of line wire diameters always occupy a position in which they are both on the second driven roller 3 as well as on the longitudinal wire 1.
  • the Pressure roller 4 can be moved to its rest position by the piston-cylinder arrangement 10 is drawn in so that the free end 9 of Auslergers 7 is moved up in the drawing.
  • the entire width of the mesh mat to be welded is one pneumatic or hydraulic loading of the piston-cylinder arrangement 10 advantageous because then even Pressure conditions of the entire system are ensured.
  • piston-cylinder assemblies 10 each offset be arranged, as can be seen from both drawings, so to enable that desired narrow grid dimension.
  • each boom 7 provided with two holes 14 from which only one is used as pivot point 8.
  • the choice of each hole 14 used for the pivot point 8 depends depending on which of the two points of attack 12 for the attachment the piston-cylinder arrangement 10 is used.
  • the geometry of the boom 7 and the swivel arm 5 and their the arrangement of the second driven roller 3 ensures that the pressure roller rests with more force on the roller 3 than on the Line wire 1, that is, the force vectors of the pressing force one larger vector from the pressure roller 4 to the roller 3 than to the line wire 1 result. This ensures that the pressure roller 4 is not as pure Pinch roller works with the mentioned possible disadvantages, but always represents a drive roller for the line wire.

Claims (5)

  1. Dispositif d'avance pour fils longitudinaux sur une machine de soudage par écrasement, avec un cylindre entraíné en contact avec les fils longitudinaux, et avec un rouleau presseur, qui est disposé du côté du fil longitudinal opposé au cylindre, et qui est monté mobile d'une position de repos dans une position de travail, dans laquelle il est en contact avec le fil longitudinal, caractérisé en ce que le rouleau presseur (4) est également entraíné par un deuxième cylindre entraíné (3), le rouleau presseur (4) étant en contact, dans sa position de travail, à la fois avec le deuxième cylindre entraíné (3) et avec le fil longitudinal (1).
  2. Dispositif d'avance selon la revendication 1, caractérisé en ce que le rouleau presseur (4) est monté libre à pivotement sur une console (7), la console (7) étant montée mobile au moyen d'un dispositif hydraulique, pneumatique ou similaire (arrangement piston-cylindre 10) et de manière à pouvoir se déplacer autour d'un point de pivotement (8), pour amener le rouleau presseur (4) soit dans sa position de repos, soit dans sa position de travail.
  3. Dispositif d'avance selon la revendication 2, caractérisé en ce que deux points d'attache différents (12) du dispositif d'entraínement hydraulique, pneumatique ou similaire (arrangement piston-cylindre 10) sont prévus pour la console (7), et en ce que deux points d'appui (alésages 14) sont également prévus sur la console (7), avec lesquels la console (7) peut être montée à pivotement, de telle sorte que, pour les deux possibilités différentes de fixation du dispositif d'entraínement (piston-cylindre 10), pour à chaque fois la même course de déplacement du dispositif d'entraínement, il en résulte un même déplacement du rouleau presseur (4) en raison du déplacement de pivotement de la console (7).
  4. Dispositif d'avance selon l'une quelconque des revendications précédentes, caractérisé en ce qu'à la fois le premier cylindre entraíné (2) et le rouleau presseur (4) présentent une surface lisse.
  5. Dispositif d'avance selon l'une quelconque des revendications précédentes, caractérisé en ce que dans l'arrangement du rouleau presseur (4) dans sa position de travail entre les deux cylindres entraínés (3) et la console (7), il existe un vecteur force de pression supérieur entre le deuxième cylindre entraíné (3) et le rouleau presseur (4) qu'entre le rouleau presseur (4) et le fil longitudinal (1).
