Definitions

  • said part filling in elastic material is in two parts distinct, touching end to end once introduced in the profile, each part of said piece of filling with a channel opening to a single end and being blind at the opposite end, the end where the channel opens out being linked to a metal insert of jaw tightening and hydraulic pressure supply and equipped with a means of connection to means hydraulic pressurization, said metal insert penetrating into the corresponding end of the profile.
  • each part 20 A (20 B) of the filling part 20 is hollowed out with a blind channel 21 at one end and opening at the other.
  • it is equipped with means 23 for connection to a circuit hydraulics including 24 regulation and a pump hydraulic 25 ( Figures 2 and 3).
  • a counterform 15 with a recess 26 we have shown a counterform 15 with a recess 26.
  • hydraulic pressure P is sent, ensuring expansion of the filling part 20 and the plating of the profile 6 against the surfaces of the channel formed by form 3 and the platform 15 closed against each other.
  • Figure 7 is a section along VII-VII of the figure 6 but before the pressurization of the part 20 by the channel 21 while in FIG. 6 the filling part 20 is shown in expanded condition and the profile 6 plated against the walls of the canal.
  • An advantage of using the coin filling 20 for securing the profile 6 against the walls of its channel-shaped housing consists of that the profile does not need to be cleaned after its installation in shape since it is not in contact with the hydro-forming liquid, the two parts 20 A and 20 B of the piece of filling being waterproof.
  • the pressurization of channel 21 can be carried out at will before, simultaneously or successively with a drawing operation by the jaws 4.5 by means of the jacks 6.7.
  • Figures 8 and 9, respectively equivalent to Figures 6 and 7 show the case of bending and forming of a section 6 with open section.
  • This variant can in particular be used when the profile 1 to be formed is short in length.
  • the elastic filling part 20 is in one only part.
  • the effort F can be carried out only by a single end, in which case the other end is closed by a metal insert for clamping the jaws 4, solid, without piston tail hole, filler piece leaning directly against this insert.
