Definitions

  • the bending head 11 considered here has a body 14 of cylindrical shape, split longitudinally, which is rigidly connected to the carriage 8.
  • the longitudinal slot 15 of the body 14 has a width provided so as to allow the passage of the tube 4 to be bent.
  • a cylindrical slide 29 having at one end an annular groove 30.
  • a pusher 31 parallel to the axis 5 and eccentric relative to this axis, crosses slidingly the enlarged part 18 of the shaft 16.
  • One end of the pusher 31 forms an enlarged head 32, introduced into the annular groove 30 of the slider 29.
  • the pusher 31 laterally comprises a rack 33, coming in taken with the pinion 24 secured to the arm 25.
  • the second bending head 13 realizes according to the same process an elbow at a point on the right half of the tube 4.
  • the positioning and the control of this second bending head are provided by the geared motor 12 already mentioned, as well as by two other geared motors 40 and 41 (see FIG. 1), which correspond respectively to the geared motors 20 and 36 of the first bending head 11 .
  • the elbow executed by the second bending head 13 on the right half of the tube 4 can be produced in a bending plane which is different from the bending plane of the elbow executed on the left half by the first bending head 11.
