  • the means 12 for moving the upper unit 3 are generally double-acting hydraulic cylinders to which the chassis 30 is attached.
  • the means 12 'for moving the lower unit 3' can be simple mechanical jacks on which the unit 3 'is placed and which also make it possible to adjust the position of the latter, returning to the rest position. by gravity.
  • the chassis 3 of the upper bending unit is rotatably mounted on two support members 5 and 6, by means of two pins 33, 34 placed respectively at its two ends and centered on a horizontal axis 35 parallel to the axis 40 of the working cylinder 4.
  • the support member 5 placed on the dismantling side that is to say on the operator side, comprises an annular part 51 constituting a bearing body in which the pin 33 is rotatably mounted.

  • the beam 3 is provided with suspension members 36 which can be removably engaged on jacks 12 fixed on the sides 10 of the frame and constituting the means for controlling the vertical movement of the bending unit 3.
  • the rod of each cylinder 12 can be provided with an enlarged head 13 which can slide into a mortise 37 formed on the corresponding suspension part 36 of the chassis 30.
  • the frame 30 of the upper flexion unit 3 is therefore fixed by the parts 36 to the rods 13 of the two support cylinders 12 which allow the flexion unit to be placed 3, either in a raised rest position for which the working cylinder 4 is moved away from the passage plane P of the strip, or in a lowered position, for which the working cylinder 4 is at a working level adjusted by stops and allowing to apply a determined flexion to the strip M.
  • the bending unit 3 can be detached from the jacks 12 by simple horizontal displacement parallel to the axes 40 of the cylinders.
  • the carriage 2 comprises a horizontal frame 21 bearing on the floor 15 by means of rollers 22 and being able to move horizontally and in a direction transverse to the longitudinal direction of travel under the action of a jack 23 whose body is articulated on the frame 10 of the machine and whose rod is articulated on the chassis 21 of the carriage 2.
  • the latter can thus take two positions, respectively a position of support for which the frame 21 is threaded into the base 11 of the frame 10 of the machine and a disassembly position, shown in Figure 2, for which the frame 21 is spaced laterally on the operator side.
  • the transfer carriage 2 further comprises support pieces 24, 25 in the form of an easel, integral with the horizontal frame 21 and extending vertically on different levels corresponding respectively to the different bending units.
  • the easel 24 for supporting the upper bending unit 3 extends to a level slightly lower than that of the axis of rotation 35 and is provided a removable fixing member of the support member 5, placed on the operator side, and which may be constituted by a jack 7.
  • the jack 7 comprises a body 71 mounted on the easel 24 optionally by means of shims of adjustable thicknesses and a rod 72 which is provided with a support plate 73 and a stud 74.
  • the easel 24 is aligned with the support member 5 and, by actuating the jack 7, the plate 73 comes to bear on the bearing body 51 which is provided with a housing 52 in which the stud 74 engages.
  • the support member 6 placed at the opposite end of the chassis 30 of the flexion unit 3 bears itself, by means of rolling rollers 63, on horizontal rails 14 extending transversely between the two 10 sides of the frame.
  • each roller 63 is mounted at the free end of an arm 64, the other end of which is articulated, around a horizontal axis 65, on the flange 61 of the member support 6.
  • Springs 66 stretched between each arm 64 and an attachment piece 67 secured to the flange 61 make it possible to maintain the chassis 30 in the raised position shown in FIG. 2 and for which the suspension pieces 36 are at the level heads 13 of the control cylinders 12.
  • Screws 68 make it possible to adjust the upper position in which the chassis 30 is returned under the action of the springs 66 so that, in this position, the mortises 37 are located exactly at the desired level.
  • the upper unit 3 When the upper unit 3 is in the disassembly position shown in Figure 2, it is possible to rotate it, for example manually, around the horizontal axis 35 defined by the pins 33 and 34, the assembly being able to be balanced to facilitate turning.
  • the unit 3 is locked in the inverted position by suitable means which will be described later.
  • the working cylinder 4 is turned upwards by resting on the intermediate cylinders 41 and it is therefore easy to intervene on the cylinders, for example to clean, repair or replace them.
  • the unit 3 can in fact be transported in its inverted position by means of hooks 48 placed at the level of the cylinders, or else of bars passing through holes 49 made in the chassis 30. In this way, it is avoided having to turn over unit 3 in the workshop, this operation being made more easily on site thanks to the arrangements according to the invention.
  • a means for locking the chassis 30 in the position reversed is shown in detail, by way of example, in Figure 5.
  • the support member 5 is provided with a fixing device 53 comprising a finger 54 which can engage in a bore 55 diametrically passing through the pin 33.
  • the support member 6, placed on the opposite side is fitted with a similar fixing device.
  • the chassis 30 is thus fixed in the inverted position presented in FIG. 3. In this position, each working cylinder 4 is turned upwards and simply rests on the intermediate cylinders 41, the latter resting themselves on the three rows of rollers 42.
  • the de-camber cylinder must have a larger diameter and can possibly resist bending alone by resting on its bearings 32, the support rollers 42 then being deleted.
  • the invention therefore makes it possible to intervene very easily on the bending unit 3 in order to maintain or replace one or the other of the cylinders 4 and 41 as well as the support rollers 42, if necessary. Then, it suffices to remove the two pins 54 and rotate the frame 30 to bring it back to the working position for which the working rolls are turned downwards.
  • each lower bending unit 3 ′ will be mounted in a simpler manner, the support members being eliminated.
  • the end plate 311 turned on the operator side is provided with a simple console portion 350 which can rest on a jack 75 mounted on the bridge 25 and whose rod is provided, as before, with a stud. coming to engage in a corresponding housing of the console 350 so that the chassis 30 ′ is driven by the transfer carriage 2 for disassembly.
  • the opposite plate 312 bears directly on rails 14' by means of rollers 63 '.
  • the chassis 30 ' can be provided with hooking members 37' which engage on the actuator rods 12 'for controlling the movement which, in the example shown, are mechanical jacks.
