Definitions

  • the present invention relates to a machine for bending sections of thin and straight metal elements of the son, strip or tube type, this machine comprising positioning means for maintaining a section of metal element to bend on a first axis, and at least one folding member which cooperates with a folding counterpart placed on said first axis and which, on the one hand under the action of a first drive mechanism, can be driven by an angular rotation movement around a second axis perpendicular to the first at right of the folding counterpart and, on the other hand, by means of a second drive mechanism, can be moved in a reciprocating movement on a third axis parallel to the second, said folding member being further movable, together with the folding counterpart, in a direction parallel to the first axis, while said positioning means comprise a clamp which is intended to imm obilize the section of metal element to be folded on said first axis and which is also coupled to a third drive mechanism capable of imparting to it an angular rotation movement around this axis.
  • the succession of these movements makes it possible first of all to bring the folding member into lateral contact with the wire, then to make it rotate through a certain angle, in one direction or the other, so that it folds the wire around the folding counterpart, and finally to retract it before the folding member is moved with the folding counterpart.
  • the degree of bending of the wire is a function of the angle by which the bending member is rotated and the advance of the latter determines the length of the segment of bent wire.
  • the possibility of rotation of the clamp around the first axis makes it possible to modify at will the orientation of the folding member, with respect to the wire, in a plane perpendicular to the latter and consequently, the member bending can, at each of its stops along the wire, arch the latter in a different spatial direction.
  • the bending wire is, on each side of the pliers, retained between two positioning pins with fixed spacing, integral with the underside of the corresponding folding head, one of these lugs constituting the 'folding member and the other, centered on the second axis or axis of rotation mentioned above, constituting the associated folding counterpart.
  • This particular structure with fixed positioning lugs has the drawback of limiting bending to a single type of wire having a given diameter corresponding to the mutual spacing of the two lugs.
  • these positioning pins which enclose the wire to be bent may hinder the movement in translation, along the latter, of the folding head which carries them.
  • the present invention aims to remedy all these drawbacks by proposing a cambering machine of the type specified in the preamble, which is characterized in that said positioning mechanism further comprises a pair of jaws, movable in block together with the folding member. , and at least one of which can be moved laterally so as to be distant from the second jaw, under the control of an actuating mechanism which occurs during the movement of the folding member along the first axis, the beaks of these jaws constituting said folding counterpart.
  • This pair of jaws advantageously replaces the positioning pins of the prior art by eliminating the aforementioned drawbacks linked to the latter.
  • the cambering machine comprises two folding members each associated with a folding counterpart and arranged on either side of the clamp.
  • the clamp is formed by a disc provided with a radial slot opening on its periphery and mounted for rotation about its center on a support arm secured to the frame of the machine, this disc further comprising members for clamping the section of metal element to be folded.
  • the clamp opposes an extremely reduced inertia to its rotation.
  • the clamping members are constituted by tabs projecting from the edges of the slot opposite one another at the center of the disc, at least one of these tabs being movable and displaceable against the action of an elastic element which urges it towards the other cleat.
  • the cambering machine comprises a member for moving the movable cleat, constituted by a jack whose rod comes, in a certain angular position of the disc, in alignment with a bore of the latter, open on its periphery, in which slides a rod secured to the movable cleat.
  • the third drive mechanism ensuring the rotation of the disc comprises a motor coupled to a shaft which carries, over at least part of its length, a toothing meshing with a toothed crown carried by the periphery of the disc and tangent to the tree.
  • each folding member is constituted by a folding finger mounted to slide on said third axis in a support head which has an axis of symmetry constituting the second axis and which is kept in rotation around it. the latter inside a movable frame on a rail parallel to the first axis.
  • This folding finger is of a very reduced weight and opposes an almost negligible inertia to the actuation of its movement mechanism. As a result, its back and forth movement is instantaneous, which has a favorable influence on the working speed and the productivity of the bending machine according to the invention.
  • the first folding finger drive mechanism comprises an endless chain extending parallel to the first axis around two toothed wheels, one of which is fixed coaxially around the support head and the other is carried by a loose shaft mounted for free rotation in the frame, parallel to the axis of rotation of the support head, one of the strands of the endless chain being connected to the free end of the rod of a jack which is parallel.
  • the endless chain is a silent chain and the free end of the cylinder rod is slidably mounted along a guide rail parallel to the rod.
  • This mode of driving the folding member in rotation has the advantage, on the one hand, of being very precise as regards the repeatability of the folding angles, and on the other hand, of produce very low angular rotations of up to 1/10 of a degree.
  • the second folding finger drive mechanism comprises a jack integral with the frame, the rod of which passes freely through the support head along the axis of rotation of the latter, the free end of this rod being connected to the folding finger by a rotating side link.
  • the first, second and third drive mechanisms as well as the jaw control system and that of the movement of the folding members are actuated in synchronism by a programmable digital control with programming. assisted.

  • the admission and evacuation of the working fluid into and out of the cylinders of the two jacks is done through conduits 14, 15 connected, by means of a relay 16, to a hydraulic unit not shown.
  • each of the folding devices 3 or 4 carries, on a vertical flat face, two jaws 17, 18 mounted on either side of the axis of rotation X of the support clamp 2, the upper jaw 17 being able to be moved away from the lower jaw 18 by means of a hydraulic jack 19 visible in FIG. 2, which represents in section, one of the folding devices 3 or 4.
  • the essential member of this folding device is constituted by a folding finger 20 projecting from the front face 21 of a support head 22 rotatably mounted about its axis of symmetry Y and, by means of two bearings 24, 25, in the frame 23, l ' axis of rotation Y of the support head 22 being horizontal and perpendicular to the axis of rotation X of the support clamp 2.

  • the support head 22 can be driven in an angular rotational movement under the action of a first drive mechanism 28 housed in an interior cavity 29 of the frame 23.
  • this first drive mechanism 28 comprises an endless chain 30, preferably a silent chain, which is wound around two toothed wheels 31, 32, the one 31 is fixed coaxially around the support head 22 and the other 32 is carried by a loose shaft 33 held in rotation in the frame 23 about an axis parallel to that Y of the support head.

  • the free end of the rod the jack 35 is also slidably mounted by means of a ball bushing 37, along a cylindrical rail 38 parallel to the strands of the chain 30 and fixed by its ends to the frame 23.
  • the endless chain 30, driven in one direction or the other by the jack 36 rotates the support head 22 by an angle determined by the stroke of the jack rod, this angular rotation being transmitted to the folding finger 20 which describes an arc of a circle with the same angle in the center, around the axis Y.
  • the finger 20 and the spouts 26 and 27 of the two jaws 17 and 18 are each provided with a groove intended to receive the wire F, these grooves having the shape of a V to be adapted to all wire diameters.

  • This second drive mechanism 39 more specifically comprises a pneumatic cylinder 40 externally fixed on the rear wall 41 of the frame 23, in which an opening 42 is made through which the rod 43 of the cylinder is formed.
  • the cylinder rod 43 passes freely through the support head 22, along the axis Y and, at its free end, opens into an interior cavity 44 of the support head where it is connected to the folding finger 20 by a rotary link 45. Thanks to this link, the finger 20 can be rotated about the axis Y while being able to be moved in translation by the jack rod 43, whatever its angular position. In this way, after having made a folding, the finger 20 can be retracted to then be placed on the other side of the wire in order to practice on it folding in the opposite direction, after a displacement of the folding device relative over.
  • the three jacks 19, 36 and 40 which have just been mentioned, are put into action by means of a working fluid coming from a power station through the relay 16 and conveyed by flexible conduits 19a held inside curved gutters 19b which are formed by several U-shaped elements 19c hinged end to end, so as to be able to follow the movement of the two folding devices 3 and 4 (see FIG. 1).
