  • the jaw device 5 consists of a first clamping jaw said fixed jaw 6 and a second clamping jaw said movable jaw 7.
  • the electric machine 1 comprises between the electric motor 4 and the jaw device 5 and centered on the longitudinal axis xx 'a movable thrust trolley 8 which is guided in translation on rails 9 integral with the frame 2.
  • the electric motor 4 comprises an output shaft associated with a transmission screw 24 of thrust forces whose free end cooperates with the movable thrust trolley 8 to ensure said carriage its movements along the longitudinal axis xx 'in order to bring it closer or away from the end of the profile 3 to deform.
  • the movable thrust trolley 8 comprises, centered on the longitudinal axis xx 'of the electric machine 1, a tool carrier 10 which is slidably mounted on a slide device 11 so that said tool carrier 10 can move relative to the movable carriage thrust 8 in a transverse direction and perpendicular to the longitudinal axis xx '. of the electric machine 1.
  • the tool carrier 10 is driven in its displacements by means of an electric jack 12 fixed on the mobile thrust carriage 8.
  • the tool holder 10 comprises retaining devices 13 allowing the fixing of punches 14 shaped to ensure the deformation by successive pressures of the free end of the profile 3 retained in the jaw device 5.
  • the tool holder 10 comprises between two punches 14 a material-making stop 15 for adjusting the length of the end of the profile 3 to be deformed.
  • the movable thrust carriage 8 comprises, shifted laterally with respect to the longitudinal axis xx 'of the electric machine 1, a cam holder 16 carried by a longitudinal axis cc' parallel to the longitudinal axis xx '.
  • the cam holder 16 is integral with a cam 17 of rectangular section cooperating as a function of its axial position and longitudinal displacements of the mobile thrust carriage 8 with a clamping device 18 actuating the movable clamping jaw 7 of the jaw device 5.
  • the cam holder 16 is rotated about its longitudinal axis cc 'by means of an electric or pneumatic jack 19 fixed on the mobile thrust carriage 8.
  • the electric machine 1 comprises on the fixed frame 2 a pre-clamping device 22 consisting of an electric or pneumatic jack 23 acting on the movable clamping jaw 7 of the jaw device 5 to allow pre-clamping of the profile 3 between the jaws 6, 7.
  • a pre-clamping device 22 consisting of an electric or pneumatic jack 23 acting on the movable clamping jaw 7 of the jaw device 5 to allow pre-clamping of the profile 3 between the jaws 6, 7.
  • the figure 4 shows the adjustment of the length of the end of the profile 3 to be conformed.
  • the profile 3 is positioned and held between the jaws 6, 7 of the jaw device 5.
  • the tool holder 10 is moved on the movable thrust trolley 8 in a direction parallel to the yy 'axis of the electric machine 1 by the electric or pneumatic cylinder 12 to position the material stopper 15 on the axis xx'.
  • the movable thrust trolley 8 is moved by the thrust transmission screw 24 connected to the electric motor 4 in the direction of the end of the profile 3 along the axis xx 'to bring against the end of the profile 3 the stop of take material 15 and adjust the length of the latter depending on the conformation to achieve.
  • the cam gate 16 and more particularly the cam 17 is positioned (e) via the electric or pneumatic cylinder 19 in its angular position of smaller dimension so that said cam 17 does not come into operation. contact with the pressure rollers 20, 21 of the clamping device 18.
  • the figure 5 shows the pre-tightening of the movable clamping jaw 7 of the jaw device 5 around the profile 3 before the deformation of its end.
  • the electric or pneumatic cylinder 23 of the pre-clamping device 22 is actuated so that the movable jaw 7 comes to press pre-tightened against the profile 3 in order to maintain the latter between the jaws 6, 7 of the jaw device 5.
  • the movable thrust trolley 8 is remote from the end of the profile 3 to be deformed, causing the cam holder 16 and the cam 17 to retract.
  • the tool holder 10 After moving the movable thrust trolley 8, the tool holder 10 is moved transversely by means of the electric or pneumatic cylinder 12 along the slide 11 in order to position the first punch 14 on the axis xx 'and in front of the end of the profile 3 to conform.
  • the electric or pneumatic cylinder 19 rotates the cam 17 to place the latter in its angular position of larger size.
  • the figure 6 shows the clamping jaws 6, 7 in the tight position around the profile 3 just before the deformation of its end by means of the punch 14 of the tool holder 10.
  • the tight position of the jaw device 5 and more particularly the movable jaw 7 against the profile 3 is obtained by moving the movable thrust trolley 8 towards the end of the profile 3 to be shaped so that the cam 17 disposed in its angular position of greater dimension comes to bear against the pressure rollers 20, 21 of the clamping device 18.
  • the introduction of the cam 17 between the pressure rollers 20, 21 makes it possible to act more particularly on the mobile pressure roller 20 so that the latter, because of the dimensions of the cam 17, comes to push on a spring device 25 amplifying the pressure forces of the mobile pressure roller 20. Under the thrust of the mobile pressure roller 20, the spring device 25 exerts an amplified pressure allowing the movable jaw 7 to clamp and lock the profile 3 in the jaw device 5.
  • the figure 7 shows the electric machine 1 in striking position allowing the punch 14 to perform the deformation of the end of the profile 3 in a specific form.
  • the punch change 14 is obtained by a retreat of the movable thrust trolley 8.
  • the recoil of the movable thrust trolley 8 is provided so as to release only the punch 14 from the end of the profile 3 without completely removing the cam 17 of the rollers pressers 20, 21 for maintaining the pressure force on the spring device 25 and the movable jaw 7 of the jaw device 5.
  • the cam 17 has a working length which is sufficient to maintain the pressure rollers 20, 21 in pressure while the movable thrust carriage 8 makes movements of short stroke along the axis xx '.
  • the change of punch is obtained by moving the tool carrier in a direction transverse and parallel to the axis yy 'of the electric machine 1 so as to present on the axis xx' another punch 14 of different shape and complementary to continue conformation of the end of the profile 3.
  • profiles 3 are positioned between the jaws 6, 7 of the jaw device 5 via a feed device, not shown, for example to automate the supply of the electric machine 1.
  • the electric machine 1 is connected to a central programming and control unit, not shown, to act on all the mobile production elements.
  • the machine 1 may comprise a protective cap 30 hinged to the fixed frame 2 and coming to close and protect the production area and the moving elements.
  • the electrical machine 1 may have a tool carrier 10 with a circular profile rotated about its axis and making it possible to accept a greater number of punches 14 or other tools for shaping the end of the profile 3.
