Definitions

  • the present invention relates to an automatic machine for bending, according to a predetermined configuration, thin and straight metal elements of constant thickness such as wires, strips or tubes, this machine comprising a dispensing member through which a metal element to be bent can be moved in a forward movement in steps by means of an advance device, a folding member which is located downstream and close to the outlet of the distributor member and which can, on the one hand, by means of of a first drive mechanism, being driven by an angular rotational movement about an axis perpendicular to the direction of advance of the metal element and, on the other hand, by means of a second mechanism drive, be moved in a reciprocating movement on a rectilinear trajectory parallel to this axis, the operations of the first and second drive mechanisms being synchronized with that of the advance device according to a pr cycle determined.
  • Cambering machines of this type are currently the most efficient because of their automatic operation and the possibility that they offer of continuously bending thin and straight metal elements.
  • the succession of these movements makes it possible, first of all, to bring the folding member into lateral contact with the segment of wire emerging from the dispensing member, then to rotate it, at a certain angle, in a direction or in the other, so that it folds this segment of wire around the point of exit from the dispensing member and finally retracts it to allow the advance of the wire for the next folding cycle.
  • the degree of wire bending is a function of the angle by which the bending member is rotated, while the length of the folded wire segment is determined by the pitch of the advancing device.
  • the essential mechanical element used in the construction of a bending machine of this known type is constituted by a cylindrical bending head whose axis of symmetry is perpendicular to the direction of advance of the wire to be bent.
  • this head On its face facing the outlet of the dispensing member, this head carries the actual folding member which is rormé by a fixed finger eccentric relative to the axis of symmetry of the head; the reciprocating movement of this folding member takes place under the action of a jack which moves the entire folding head while its angular rotation is produced by a stepping motor which rotates the folding head around its axis of symmetry-In this first known machine, the particular structure of the folding member and its drive means is the cause of 'a number of disadvantages.
  • the slides which are mounted side by side on the frame of the machine comprise folding heads of different shapes cooperating with complementary counter-dies and can be oriented in any direction of space.
  • a wire placed between the folding heads of the slides and the associated counter-dies can be bent, after actuation of the slides, according to a spatial configuration which is defined by the orientation and the working stroke of the slides as well as by the shape of their folding head.
  • the present invention proposes to remedy all these drawbacks and, to do this, it relates to a cambering machine of the type specified in the preamble, which is characterized in that it further comprises means for generating a rotational movement. relative angularity between the folding member and the metallic element, around a second axis coincident with the direction of advance of the metallic element, this relative angular rotational movement being synchronized with the two other movements of the member folding and forward movement by steps of the metal element.
  • the axis of rotation of the folding member can be oriented in any direction, with respect to the metallic element inside a plane perpendicular to the direction of advance of this latest.
  • the folding member can therefore bend wires in all directions of space and the machine according to the invention is able to produce, at a high and continuous rate, wires bent according to any configuration. spatial. It can thus be observed that the cambering machine according to the invention has all the advantages of the above-mentioned first known machine for folding in a single plane, without having the disadvantages of the multiple slide machine for spatial folding.
  • the folding member is mounted for rotation about the second axis and the means for generating said relative angular movement are constituted by a third drive mechanism under the action of which the member folding can be driven by an angular rotational movement around this axis.
  • This embodiment of the bending machine according to the invention is more particularly suitable for the manufacture of articles produced by folding a continuous metallic element; each finished article being separated from the latter by a shear which acts at the outlet of the distributor member,
  • the distributor member is constituted by a cylindrical barrel of circular section whose axis of symmetry constitutes said second axis
  • the folding member consists of a folding finger mounted to slide on said rectilinear trajectory, in a support head which has an axis of symmetry constituting the first axis and which is kept in rotation around this axis inside a frame itself mounted in rotation around the distributor barrel, the first, second and third drive mechanisms acting respectively on the support head, the folding finger, and the frame.
  • this folding finger is of a very reduced weight and opposes an almost negligible inertia to the actuation of its movement mechanism.
  • 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 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 lateral link, which allows the folding finger to rotate around the cylinder rod while being able to be moved in translation by the latter, in any angular position.
  • the first folding finger drive mechanism comprises an endless chain driven parallel to the direction of advance of the wire around two toothed wheels, one of which is fixed coaxially around the head and the other is carried by a loose shaft mounted to rotate freely on 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 extends in the direction of drive of the endless chain.
  • This mode of driving the folding member in rotation has the advantage, on the one hand, of being very precise with regard to the repeatability of the folding angles and, on the other hand, of producing very low angular rotations up to 1/10 of a degree.
  • a silent endless chain is used and it is further provided that the free end of the cylinder rod is slidably mounted along a guide rail parallel to the stem.
  • the third folding finger drive mechanism comprises a large diameter toothed wheel secured to the frame and centered around the axis of rotation of the latter, this large diameter toothed wheel meshing with a small diameter toothed wheel keyed to a shaft, which is driven, via a chain drive without play, by a stepping motor.
  • the various drive mechanisms of the folding member as well as the advance device are actuated in synchronism by a programmable digital control with assisted programming.
  • the machine which is the subject of the present invention is specially designed for producing articles of folded wire in succession, by bending a continuous metal wire.
  • this is not a limiting application of this machine which, with a reduced number of structural modifications, can be used to produce articles produced by bending any other type of thin and straight metal elements, of constant thickness, such as strips or small diameter tubes.
  • This machine can also be used for bending simple segments of metallic elements of this type.
  • This straightening device consists of a number of rollers 3 mounted free to rotate on the chassis 4 of the machine and arranged in staggered rows on two parallel rows which delimit a passage for the wire 1.
  • the wire which has a certain curvature at its exit from the reel, is made rectilinear.
  • the height of the passage defined by the two rows of rollers can be adjusted by known means depending on the diameter of the wire.
  • a step advancing device 5 housed in a casing 6 which is fixed to the chassis 4 of the machine.
  • This advance device 5 consists of a movable clamp 7 and a fixed clamp 8.
  • the movable clamp 7 is slidably mounted on a cylindrical rail 9 parallel to the direction of advance of the wire 1 and is fixed to the end of the rod 10 of a jack 11 carried by the casing 6.
  • the fixed clamp 8 is in turn secured to the rail 9, near its end opposite to the jack 11.
  • the opening and closing of the two clamps 7 ei are controlled by conventional means known per se.
  • the movable clamp grasps the wire 1 which enters the casing 6 through an opening in the rear wall of the latter. Then the fixed clamp 8 being open, the movable clamp 7, moved along the rail 9 by the jack 11, advances the wire 1 over a distance determined by the stroke of the latter. The fixed gripper is then closed and the jack brings the movable gripper back to its starting position in the open position for a new wire advance cycle 1. In this way, the movable gripper 7 advances the wire 1 according to a straight path and in successive steps not necessarily identical, in the direction of the folding device 12 of the machine.
  • this folding device 12 comprises a cylindrical distributor barrel 13 of circular section, which is secured to the chassis of the machine and which extends in the extension of the advancement device 5 so as to direct the wire 1, displaced in translation by the latter, up to a movable folding member 14 which ensures the actual bending of the segment of wire emerging from the dispensing barrel, around the point of exit of the latter.
  • a shears 15 is also automatically brought, by an actuation system not shown, to the exit point of the distributor barrel to separate by section each finished article from the wire 1.
  • the longitudinal passage 17 has a diameter significantly greater than the maximum diameter that the wire passing through it can have.
  • the channel 20 of the nozzle 18 has a diameter strictly equal to that of the wire to be bent so that the latter slides without play inside the nozzle. Consequently, there must be a set of nozzles adapted to each diameter of wire to be bent.
  • the nozzle chosen is fixed to the end 19 of the barrel 13 by a screw 21 but, as a variant, it is possible to provide for the same purpose, a bayonet fixing.
  • the movable folding member 14 is carried by a frame 22 so as to be arranged opposite and very close to the outlet point of the nozzle 18.
  • the folding member 14 Under the action of a first mechanism drive, 24, the folding member 14 can be driven in an angular rotational movement about an axis Y which extends per to the direction of advance of the wire 1 in alignment with the point of outlet of the distributor barrel 13.
  • a second drive mechanism 23 makes it possible to move the folding member 14 in a reciprocating movement on a rectilinear trajectory X parallel to the axis Y.
  • the folding member 14 can be brought into lateral contact with the segment of wire leaving the barrel 13 and then bend it at a certain angle in one direction or the other around the tip of the nozzle 18. But as can easily be understood, a folding member having only these two possibilities of movement can only fold ier the wire in a plane perpendicular to its axis of rotation.
  • the frame 22 which carries the folding member 14 is rotatably mounted around the cylindrical distributor barrel 13, by means of two bearings 25 and can be driven by an angular rotation movement transmitted by a third drive mechanism which will be described later with reference to Figure 4. Therefore, the folding member 14 has a third possibility of movement which consists of an angular rotation around d 'a second axis coincident with the longitudinal axis of symmetry of the passage 17 of the barrel 13, that is to say with the direction of advance of the wire 1.
  • the member folding 14 can arch the wire 1 in all directions of space and the machine according to the invention can produce folded wires according to a spatial configuration.
  • the folding member 1 4 is constituted by a cylindrical finger mounted sliding along the path X in a support head 26 which is itself held in rotation inside the front part of the frame 22 via of two bearings 27, 28.
  • the folding finger 14 is eccentric relative to the axis of symmetry of the support head 26, which in fact constitutes the axis of rotation Y mentioned above.
  • the folding finger 14 Under the action of the second mechanism 23, the folding finger 14 can sometimes be taken out of its support head 26 for positioning against the wire 1, sometimes retracted to allow the wire 1 to advance at the end of a folding cycle. It will be observed that, by its reduced weight, the folding finger 14 opposes a practically negligible inertia to the action of the drive mechanism 23; its back-and-forth movement is therefore instantaneous, which has the consequence of increasing the working speed and the productivity of the bending machine according to the invention.
  • the drive mechanism 23 more precisely comprises a hydraulic cylinder 29 fixed to the upper wall 30 of the frame 22, in which an opening 31 is made through which the rod 32 of the cylinder is formed.
  • the actuator rod 32 passes freely through the support head 26, along the axis Y and, at its free end, opens into an interior cavity 35 of the support head where it is connected to the folding finger 14 by a rotary link 36. Thanks to this link, the finger 14 can be rotated m5 about the axis Y while being able to be moved in translation by the rod 34, whatever its angular position.
  • the first drive mechanism 24 of the folding finger 14 which can impart to it this angular rotation movement around the axis Y,. is housed in an interior cavity 33 of the frame 22.
  • this first drive mechanism 24 which firstly comprises an endless chain 37, the representation of which has been omitted for clarity in FIG. 2.
  • This endless chain 37 which is preferably a silent chain , cooperates with two toothed wheels 38, 39, one of which 38 is fixed coaxially around the support head 26 and the other 39 is carried by an idler shaft 40, held in rotation in the frame 22 so that its axis of rotation is parallel to that of the support head -
  • the two strands of the endless chain 39 are thus parallel to the direction of advance of the wire 1, and one of them is connected by a connecting link 41 , at the end of the rod 42 of a hydraulic cylinder 43 fixed to the rear face 44 of the frame 22.
  • the free end of the cylinder rod 42 is also slidably mounted by means of a bushing balls 45, along a cylindrical rail 46 parallel to the direction wire in advance and fixed by its ends to the frame 22.
  • the endless chain 39 driven in one direction or the other by the jack 43, rotates the support head 26 by an angle determined by the stroke of the jack rod, this angular rotation being transmitted to the folding finger 14 which describes an arc of a circle with the same angle in the center, around the axis Y.
  • the folding finger 14, in lateral contact with the wire 1 can bend the latter in a plane perpendicular to the axis Y, the degree of folding obtained being a direct function of the stroke of the rod of the jack 43.
  • this second drive mechanism is very precise. It makes it possible to produce very small angular rotations of the bending finger of the order of 0.1 °, which allows the latter to perform bends according to non-polygonal curves and in particular according to arcs of a circle.
  • the finger 14 exerts its folding action on the wire 1 by means of a V-shaped groove 47 which adapts to all the wire diameters.
  • the folding finger is further mounted with the rotary link 36, inside a removable cover 48 which is fixed to the rotary head, the rotary link coming to be snapped on to the free end of the rod 32 .
  • the bending plane of the wire 1 is determined, before the finger 14 comes into action by the third drive mechanism 49 which will now be described with reference to FIG. 4.
  • this third drive mechanism 49 comprises a large diameter toothed wheel 50 secured to the frame 22 and centered around the axis of rotation Z of the latter.
  • the toothed wheel 50 meshes with a toothed wheel of small diameter 51 which is keyed onto a fixed shaft 52 and which is driven by a stepping motor (of which only the shaft 54 is visible in FIG. 4), via of a silent chain transmission 53 forming a backlash without play.
  • the chain transmission 53 comprises an endless chain 55 winding around two toothed pinions 56 and 57, respectively integral with the shaft 52 of the small toothed wheel and of the motor shaft 54.
  • the endless chain 55 is further tensioned by an adjustable tension roller 58.
  • this third drive mechanism 49 a given angular displacement of the large toothed wheel 50 around the axis of rotation Z systematically orients in a desired direction, the axis of rotation Y and therefore the folding plane of wire 1, which is thus determined by the pitch of rotation of the motor.
  • the assembly constituted by the chain transmission 53, the small toothed wheel 51 and the stepping motor is housed inside a protective casing 59, which is partially open at the level of the gear of the two toothed wheels 50 and 51 and can be moved, perpendicular to their axis of rotation, for adjusting the backlash.
  • FIG. 4 also shows support pins 60 arranged in a spiral and around which the supply pipe 61 for hydraulic fluid under pressure of the jack 43 is wound during the various rotations of the wheel 50.
  • the different jacks 11, 29 and 43 of the cambering machine according to the invention are, as can be seen in FIG. 1, supplied with pressurized fluid by a hydraulic unit 62 under the control of a schematic digital console. by a square under the reference 63.
  • the motor for rotating the frame 22 as well as the device for actuating the shears 15 are also controlled by this digital control console.
  • the digital control panel contains a playback device into which a magnetic tape cassette can be inserted on which a program is pre-recorded in the form of a succession of digital instructions which. govern and synchronize the operations of the various drive mechanisms 23, 24, 49, the feed device 5 and the shear actuation device 15 of the machine according to the type of bent wire article that is wish to achieve.
  • these instructions relate, for each folding cycle, to the speed and the angle of rotation of the folding finger 14 around the two axes Y and Z, to the length and to the speed of advance of the wire, at the diameter of the latter and at the time of intervention of the shears 15.
  • the program also allows an automatic search for the origins of the various movements of the cambering machine and the management of breakdowns. It will be understood that this programmable digital control considerably increases profitability in the case of a medium or small series production since a change in the type of manufacturing requires only one replacement of a program cassette by another.
  • the program of an article can also be viewed on a standard video screen in the form of a table and the operator has the possibility of modifying any parameter of the table by the cursor of the video screen.
  • the speeds of rotation of the folding finger around the axes Y and Z can reach 277 rpm and 66 rpm respectively and that the speed of advance of the wire can go up to 1 m / s.
  • cambering machine can bend metal wires whose diameter can reach 8 mm as well as metal strips or ribbons. To fold the strips or ribbons, it is of course necessary to adapt the shape of the central passage 17 accordingly . of the distributor barrel 13 and of the channel 20 of the nozzle 18.
  • the machine according to the invention can even produce bent tubes, more particularly thanks to the very high precision of the second drive mechanism 24 of the folding finger 14, which allows a arching in a circular arc by successive keys close together.
