Definitions
- the present invention relates to a wire bending device.
- the machines of this second category all implement the same bending process which consists in passing the wire between two bending tools, one of which is fixed and the other mobile in rotation concentrically to that which is fixed.
- the wire from a spool or a boot passes through a straightener, then is taken care of by a fitting system which brings the desired length to a bending head, which is generally mobile in rotation around of the axis of the wire, and comprises a fixed finger for holding the wire and a camber roller capable of rotating concentrically with said finger in order to camber the wire.
- the change of direction of curvature is obtained by modifying the starting position of the finger and the roller, the positions of which are reversed with respect to the wire, which is achieved by axial rotation around the wire or, when said rotation is not possible , by displacement after their retraction in the head.
- This process avoids the retraction phases of the bending roller, since the two rollers can at will alternately become bending roller or fixed finger for holding the wire.
- a device comprising, in a bending head movable in rotation about the axis of the wire, on the one hand two parallel shafts, between which passes transversely, externally to said head. bending, the wire to be bent, said shafts being connected by means of a part comprising two identical toothed wheels secured to one another not coaxially by their sides, said shafts each passing axially and integrally through one of said wheels gear; on the other hand, for each of said shafts, a guide path in an arc of a circle, the guide path of one shaft being coaxial with the other shaft; and on the other hand, a toothed wheel driven in rotation in one direction or the other, positioned in the region opposite the concave parts of said guide tracks and so as to mesh with said toothed wheels.
- This device is relatively complex and has the drawback of being unreliable over time.
- the object of the present invention is to remedy this drawback by proposing a cambering device operating according to the same method, and which is of a more robust design and therefore more reliable.
- the wire bending device object of the present invention is of the type comprising a bending head carrying two bending tools between which passes the bending wire, each of said tools being capable of being rotated concentrically around the other which then is fixed, and it is essentially characterized in that it comprises:
- the axis around which the tools can rotate is arranged at the intersection of the axis of movement of the wire to be bent and a line joining the axes of the tools.
- the bending tools consist of rollers.
- the mechanical means consist of stepping motors associated with transmission means.
- the bending head is mounted in rotation on an arm, itself mounts in pivoting relation to a means for supplying the wire to be bent.
- Figure 1 shows a partial schematic view of the bending device according to the invention.
- Figures 2a, 2b and 2c show partial schematic views of the same device during different phases of a bending operation.
- a bending device which comprises a means 1 for fitting a bending wire 2 and a bending head 3.
- the fitting means 1 is capable, under the action of not shown motor means, of driving the wire 2 axially, in the direction of the bending head 3, arrow X ⁇ , or in the opposite direction, an arrow X B.
- the bending head 3 comprises two bending tools, in this case two rollers 30 and 31 mounted in free pivoting on shafts 32 and 33 respectively, and between which the wire to be bent 2 passes.
- the bending head is movable in rotation about an axis 34, parallel to the shafts 32 and 33 and, in this particular embodiment, located in the middle of the segment which joins the latter, this rotation being able to be carried out clockwise , arrow Y A , or in the opposite direction, arrow Y B.
- the bending head 3 is pivotally movable relative to the fitting means 1, so as to describe a trajectory in the form of an arc of a circle, clockwise, arrow Z A , or in the opposite direction, arrow Z B.
- roller 30 remains stationary, while roller 31 rotates concentrically with the roller 30 according to an arrow B, to arch the wire 2.
- the movement along arrow B is obtained, starting from a starting position such as that shown in FIG. 1, by the superposition of a movement along Y B and Z B , as well as, successively, movements along X B and X A.
- the movement along arrow A is obtained by superimposing a movement along Y A and Z A , as well as, successively, movements along X B and X A.
- the bending device according to the invention makes it possible to bend the wire.
- Such a bending device uses proven mechanical means, which therefore have high reliability.
