Definitions
- the present invention relates to a machine for bending and twisting flat metal wire, in particular for the production of a wiper arm for a motor vehicle.
- the arm of a wiper is made by bending a flat metal wire, for example of substantially rectangular section or the like, in order to allow it to withstand the stresses to which it is subjected, and to ensure perfect maintenance of the blade. 'wiper which, thus, can not turn on said wire.
- This metal wire is bent to allow it to match, at a distance, the contours of the vehicle, and on the other hand to give it the most suitable orientation, so that, during its alternative movement, the brush is perfectly applied against the glass.
- the object of the present invention is to remedy this drawback by proposing a machine making it possible to produce folds and twists continuously, alternately and possibly simultaneously.
- the machine for bending and twisting flat metal wire with a view in particular to the production of a wiper arm for a motor vehicle which is the subject of the present invention is essentially characterized in that it comprises means for arranging and wire retention, and at least one means capable of grasping and releasing said wire at the outlet from said supply and maintenance means, and which is, under the action of motor means associated with transmission means, mobile in several directions , on the one hand in rotation about the axis of movement of said wire, and on the other hand in movement, in one direction or another, in a direction perpendicular to the faces of said wire.
- the means capable of grasping and releasing the wire at the outlet of said supply and maintenance means is capable of coming practically into contact with the extreme part of the supply and storage means. maintaining said wire.
- the means capable of gripping and releasing the wire at the outlet of the supply and holding means is movable in rotation around an axis radial to the axis of movement of said wire and parallel to the faces thereof.
- Such a movement in rotation of the means capable of grasping and releasing the wire at the outlet of the means for arranging and holding said wire makes it possible to perform the movement of folding the wire.
- the means capable of grasping and releasing the wire at the outlet from the means for arranging and holding the wire consists of a means movable in axial displacement along an axis radial to the axis of displacement of said wire and parallel to the faces thereof.
- the axial displacement of the means able to grasp and release the wire at the outlet of the means for arranging and holding said wire allows the disengagement of said means after a folding and / or twisting operation.
- the means capable of grasping and releasing the wire at the outlet of the supply and maintenance means is in the form of a stirrup intended for come, by an axial movement, straddle said wire, said stirrup comprising two parallel branches separated by a space of a width corresponding to the thickness of said wire.
- the folding and twisting machine comprises an annular body positioned around the means for cleaning and holding said wire, capable of rotating axially around the axis of movement of the wire, and on the edge of which is mounted a tool holder capable of driving a tool in rotation about an axis radial to said axis of movement of the wire and parallel to the faces of the latter, and capable of allowing the disengagement of said tool from said thread.
- the single figure represents a partial schematic perspective view of a machine for bending and twisting flat metal wire, in particular for the manufacture of a wiper arm for a motor vehicle according to the invention. 'invention.
- the wire 2 is held by a fitting 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 from which the end part 30 of the fitting and holding means 3 passes, of which only a part is visible.
- the body 4 is movable in rotation along the double V arrow, around the axis X, under the action of motor means associated with transmission means, not shown.
- the body 4 carries an element 5 in which a tool holder 50 can rotate along an axis Y radial to the axis X and parallel to the faces 20 of the wire 2, and which preferably passes not far from the end, not visible, of the means 3 for arranging and holding the wire 2, the rotation of the tool holder 50 being represented by a double arrow P.
- the tool holder 50 carries, eccentrically with respect to the axis Y, a tool 51 in the shape of a stirrup which thus comprises two branches 52 separated by a space of a width slightly greater than the thickness of wire 2.
- the tool 51 is movable 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 achieved either by its displacement in the tool holder 50, or by the displacement of the latter in the element 5, or by the displacement of the element 5 on the body 4.
- the axial movement of the tool 51 is achieved by its movement in the tool holder 50, it is possible that the latter comprises several tools having different characteristics, dimensional for example, each capable of being extracted according to the nature of the folding to be carried out.
- twisting movement along V is carried out by the movement of the element 5 on the body 4 by a rack system for example.
- the production of a fold on the wire 2 is carried out in the following manner, the wire 2 is moved along X by the desired length, then it is held by the fitting and holding means 3 while the tool 51 is approached the wire 2 and that its two branches 52 straddle the latter near the end portion 30 of the supply means 3.
- the rotation P of the tool due to the axial rotation along Y of the tool holder 50, then allows the wire 2 to be bent.
- the radius of rotation of the tool 51 along Y is preferably small, also, the end portion 30 has clearances 31 allowing the passage of the tool 51.
- the wire 2 being bent and held in the tool 51, it is not possible to move it along X, nor to rotate the tool 51, also the latter is moved axially along S and then returned to its initial position, thus allowing the wire 2 to be released.
- the machine according to the invention also comprises means, not shown, for cutting the wire 2, allowing continuous production.
- the machine according to the invention makes it possible to chain the folds and the twists, these movements being of course carried out by means of stepping motors digitally controlled.
