Definitions

  • the present invention relates to a machine for folding and the twisting of flat wire, particularly in view of the making a wiper arm for a motor vehicle (See, for example, US-A-4,367,641).
  • the arm of a wiper is made by folding a wire flat metal, for example substantially rectangular or similar, to allow it to resist the constraints to which it is subject, and to ensure the perfect maintenance of the wiper blade which, so, can not turn on said wire.
  • This wire is bent for a allow him to marry, at a distance, the contours of the vehicle, and on the other hand give it the best orientation adapted, so that during its alternative movement, the broom be perfectly applied against the glass.
  • the present invention aims to remedy this drawback by proposing a machine allowing to realize continuously folds and tendrils, alternately and possibly in simultaneous.
  • the machine for folding and twisting flat wire into particular view of the realization of a wiper arm for motor vehicle object of the present invention is characterizes essentially in that it comprises means feeding and maintenance of the yarn, and at least one means adapted to gripping and releasing said yarn at the output of said means and maintenance, and that is, under the action of means associated with transmission means, mobile in several directions, on the one hand in rotation around the axis of movement of said wire, and secondly on the move, in a direction or in another, in a direction perpendicular to faces of said wire.
  • the rotation about an axis of movement of the wire in allows twisting, while moving, in one direction or in another, perpendicular to the faces of said wire allows perform the folding.
  • the means capable of grasping and releasing the wire in output of said feeding and holding means is suitable for coming practically in contact with the extreme part of the means for feeding and maintaining said wire.
  • the means capable of grasping and releasing the wire at the outlet of the feeding and holding means is movable in rotation about a radial axis to the axis of movement of said wire and parallel to the faces of it.
  • Such a displacement in rotation of the means capable of grasping and release the wire at the outlet of the feeding and holding means said wire makes it possible to perform the folding movement of the wire.
  • the means capable of grasping and releasing the wire at the output of the means for feeding and maintaining the wire consists in a moving means in axial displacement along a radial axis at the axis of movement of said wire and parallel to the faces thereof.
  • the axial displacement of the means capable of grasping and releasing the wire output means for feeding and maintaining said wire allows disengaging said means after a folding operation and / or twisting.
  • the means capable of grasping and release the wire out of the means of feeding and maintenance present in the form of a stirrup intended to come, by a axial movement, straddling said wire, said caliper comprising two parallel branches separated by a space of a width corresponding to the thickness of said wire.
  • the machine of folding and twisting comprises a body annular shape positioned around the means of development and maintaining said wire, able to rotate axially about the axis of moving the wire, and on the edge of which is mounted a tool holder adapted to cause a tool to rotate about an axis radial to said axis of movement of the wire and parallel to the faces of the latter, and able to allow the disengagement of said tool said thread.
  • the single figure represents a view schematic partial and in perspective of a machine for the bending and twisting of flat wire in particular to the manufacture of a wiper arm for a motor vehicle according to the invention.
  • the yarn 2 is held by a feeding and holding means 3, able to drive axially along an axis X and to immobilize the wire 2.
  • the bending head 1 comprises a body 4 in the form of a ring in the opening 40 which passes the end portion 30 of the means of feeding and maintenance 3, of which only a part is visible.
  • the body 4 is mobile in rotation according to the double arrow V, around of the X axis, under the action of motor means associated with transmission means, not shown.
  • the body 4 carries an element 5 in which a tool holder can rotate 50 along a Y axis radial to the X axis and parallel to the faces 20 of the wire 2, and which preferably passes not far from the end, not visible, means for feeding and maintaining 3 of the wire 2, the rotation of the tool holder 50 being represented by an arrow double P.
  • the tool holder 50 carries, eccentrically relative to the Y axis, a tool 51 in the form of stirrup which thus comprises two branches 52 separated by a space of slightly width greater than the wire thickness 2.
  • the tool 51 is moving in axial displacement, parallel to the Y axis, this displacement being represented by a double arrow S.
  • the axial movement of the tool 51 can be realized either by its displacement in the tool holder 50, or by the displacement of the latter in element 5, either by movement of the element 5 on the body 4.
  • twisting movement according to V is carried out by the displacement of the element 5 on the body 4 by a system with rack and pinion for example.
  • the radius of rotation of the tool 51 according to Y is preferably small, too, the extreme part 30 has clearances 31 allowing the passage of the tool 51.
  • the machine according to the invention also comprises means, not shown, cutting the wire 2, allowing a manufacturing in continued.
  • the machine according to the invention makes it possible to enchain folds and the twists, these movements being of course made by through stepper motors digitally controlled.
