Definitions

  • the present invention relates to a method and a machine for bending metal wires in three dimensions.
  • roller feed which pulls the wires, coming from a boot or a reel, through a straightener.
  • wires before introducing them, step by step, into a rotary head which performs, at each step, the folds in different planes.
  • the roller feeding device has the disadvantage of not respecting the angular position of the folds in the different planes because, during the advance, the wire can turn on itself. Also, to do this, we tried to replace the roller feed by a clip feed, so as not to let go of the wire during the advance.
  • EP-A-0 108 695 discloses an automatic bending machine with a distributor member in the axis of which the element to be bent is moved step by step using a fixed feed comprising a fixed clamp, ensuring the straightening of the wire step by step, and a folding member carried by a frame rotating around the distributor member so as to be able to arch the wire in different planes during the stepwise advance of the wire, which is held stationary in rotation.
  • Patent EP-A-0 121 826 relates to a fixed bending head, equipped with various tools arranged radially, into which the wire is introduced laterally.
  • This invention solves the problem of defining a method and creating a bending machine, with a bending head and with fixed bending tools, allowing the bending of wires in three dimensions, wire straightening without having to push it through the straightening rollers, and process management by a programmable controller.
  • the method of bending metal wires in three dimensions consists in keeping the bending head fixed and in rotating and moving the feeding devices and wire straightener around the axis of the wire, keeping the latter integral with the straightener -wire of so as to orient the wire, with a view to folding, in different planes, and to advance this step by step, towards the folding head, with a view to the formation of folds.
  • This method also consists in retaining the wire by its end during the retraction of the feeding devices and wire straightener, while the wire, has been previously detached from the feeding system, in order to obtain the straightening of the wire during during the return, towards the rear, of the feeding device.
  • the machine operating according to this process essentially consists of a fixed folding head, equipped with a tool magazine or several fixed heads and a retaining clamp, and a feeding and dressing assembly, mobile in rotation and translation.
  • the set of feeding and dressing consists of the combination of a wire straightener and a slide equipped with a feeding clamp.
  • the feed and dressing assembly moves on a guide rail by means of two slides of a screw arranged parallel to the guide rail, driven in rotation by a gear motor, and of a nut integral with one of the slides.
  • the feed and dressing assembly is rotated relative to the sliders by means of a transmission and a motor fixed to one of the two sliders.
  • Folding is carried out using one or more reciprocating or rotating tools, on shaped mandrels, mounted in a folding magazine with rotary or reciprocating movement.
  • This machine is controlled by means of a programmable automaton or any other means of this type.
  • FIG. 1 we can see a machine for bending metal wires essentially consisting of a wire straightener 1 , combined with a feed slide 2 equipped with a feed clip 3 , a guide rail 4 , a feed motor 5 , a rotation motor 6 , a screw 7 for moving the feed, a non-return clamp 8 , a tool magazine 9 , d a bending tool 10 , a transmission 11 , a folding head 12 , slides 13 and and 14 and a nut 15 for driving the wire feed 16 .
  • the wire 16 enters the folding head 12 , after having passed through the wire straightener 1 , the feed slide 2 , equipped with its feed clamp 3 and by the anti-gripper back 8 .
  • step by step, of the wire 16 and its orientation as a function of folding in different planes it suffices therefore to temporarily secure the wire 16 in the feed slide 2 , by action on the feed clamp 3 , then to put the feed motor 5 and the rotation motor 6 into operation according to predetermined sequences, controlled by the programmable controller, in order to obtain the desired folding.
  • the movement of the feed is ensured by means of the screw 7 , driven in rotation by the gear motor 5 , and by the nut 15 secured to the slide 14 which, with the slide 13 , ensures the movement of the dressing and feeding assembly with respect to the guide rail 4 , while the orientation in the chosen planes, as a function of the unfolding of the folding sequences, is obtained by means of the motor 6 and the transmission 11 .
  • a folding is carried out by a tool 10 , alternating or rotary on shaped mandrels, mounted in a tool magazine 9 , with rotary or alternating movement.
  • wire straightener 1 is integral with the feed slide 2 makes it possible to roll back the wire 16 , without constraint on the latter, in order to carry out certain types of bending or particular cuts: cutting within the radius of the bending , for example.
  • FIG. 2 a variant of the folding head is shown.
  • the wire is always referenced 16 and the non-return clamp 8 is maintained.
  • the tool magazine 9 and the bending tool 10 are eliminated in favor of the head 20 .
  • This comprises a movable structure 21 relative to the frame 22 in the vertical direction as indicated by the double arrow 23 .
  • the movement can be obtained by a motor 24 secured to the frame 22 driving a ball screw 25 but could be by any equivalent means such as a hydraulic cylinder or a stepping motor for example.
  • the mobile structure 21 comprises two displacement means 40 and 50 respectively in translation and in rotation.
  • the first displacement means has the purpose of displacing rollers 26, 27 placed on a roller bearing head 28 .
  • the latter comprises a tenon 31 , one of the lateral faces of which is machined with notches 29 in the manner of a rack 30 .
  • the post can slide into a groove 32 of a head support 33 , a groove in which the teeth of a pinion 36 can be seen extending at the end of the shaft 34 of a motor 35 .
  • the second means 50 consists of a motor 51 driving a shaft 52 itself driving through a belt 53 a hollow shaft 54 coaxial with the shaft 34 and integral with the head support 33 .
  • this folding head is as follows:
  • the wire 16 being brought in and correctly oriented by the machine, has its axis 160 situated between the rollers 26 and 27 .
  • the displacement means 40 By actuating the displacement means 40 by the shaft 34 , the pinion 36 and the rack 30 , the head 28 is brought therefore the working roller so that its axis coincides with that of the motor 35 therefore with that of the hollow shaft 54 .
  • the third means constituted by the motor 24 makes it possible to adjust the axis 160 of the wire so that it is tangent to the surface of the working roller.
  • the folding is then carried out by actuation of the shaft 52 thanks to the motor 51 , the hollow shaft rotates by a corresponding angle, driving the support 33 which by the slide 32 simultaneously drives the roller carrier head and therefore the rollers.
  • the shaft 52 thanks to the motor 51
  • the hollow shaft rotates by a corresponding angle, driving the support 33 which by the slide 32 simultaneously drives the roller carrier head and therefore the rollers.
  • the radii of curvature of the rollers can be different, which multiplies all the more possibilities by making folds of different radii.
