Definitions

  • DE-B-1 297 064 discloses a method for operating a pipe bending machine according to the preamble of the patent claim, in which the pipe to be bent is clamped between the clamping body of a bending template and the counter-clamping body of a jaw.
  • Bending template and clamping jaw are part of a swiveling bending table.
  • the tube held between the clamping bodies is bent around the bending template.
  • a push-off device is provided which acts on the still unbent tube section and pushes the tube away from the bending template. In the known method, therefore, a separate push-off device must be provided in order to detach the tube from the bending template.
  • the bending template is rotated further by a certain amount, in order to achieve by this additional rotation that the clamping surface of the bending template is removed from the bent pipe end.
  • the rotation of the bending template is carried out with the pipe standing above the amount necessary for the bending to such an extent that the bent pipe end no longer lies in the clamping surface of the bending template and the bending template is thus moved further when the pipe is "standing".
  • a slide rail 24 is pressed onto this pipe section part, which also has a groove that corresponds to the pipe radius.
  • the clamping sleeve 14 of the feed carriage 10 not only clamps the pipe section 15 firmly, but also turns it by amounts up to 360 ° if successive pipe bends are to be bent in different directions.
  • a hydraulic motor rotates a worm which interacts with a worm wheel (not shown) which is connected to the clamping sleeve 14.

Claims (1)

  1. Procédé d'utilisation d'une cintreuse de tubes, qui comporte :
       un plateau de cintrage (21) pouvant pivoter autour d'un axe, qui comporte un gabarit de cintrage (16) avec une mâchoire de serrage, et un chariot d'avancement (10) mobile qui comporte une douille de serrage (14) pouvant tourner,
       le gabarit de cintrage (16) et la mâchoire de serrage (19) comportant des corps de serrage (25) auxquels sont respectivement associées des surfaces de serrage (29 à 32 ; 33 à 35), qui sont adaptées aux tronçons de tube à cintrer,
       selon lequel, le tube (15) à cintrer est enserré entre des surfaces de serrage (33 à 35) du gabarit de cintrage (16) et de la mâchoire de serrage (19), et est cintré par une rotation du plateau de cintrage (21), et selon lequel la mâchoire de serrage (19) est desserrée du gabarit de cintrage (16) après le cintrage et le tube (15) retiré de la surface de serrage (33 à 35) du gabarit de cintrage (16),
       caractérisé en ce que,
       le retrait du tube (15) de la surface de serrage (33 à 35) du gabarit de cintrage (16) est effectué par le fait que le gabarit de cintrage (16) continue à être tourné avec le corps de serrage (25) associé, pendant que le tube (15) est retenu par le chariot d'avancement (10),
       et en ce que le tube (15) peut ensuite être tourné autour de son axe longitudinal non cintré sans obstacle de la surface de serrage (33 à 35) du gabarit de cintrage (16), et qu'ensuite l'avancement du tube pour le cintrage suivant est effectuée en même temps que la rotation de retour du gabarit de cintrage (16) dans la position de départ.
