- damping heads 59 supported by the respective linear actuators 11 abut against a pivot 60 of axis C and the transmission 23 simultaneously actuates the four mandrels 14 which, rotating around the respective axes A, twist the wire obtaining the uprights 5.
- rollers 54b impose point by point to the respective actuating rods 28 the identical displacements defined by identical radial dimensions every 90 degrees on the rolling surfaces 62 actuating the jaws 15 together with the respective guide surfaces 34.
- the jaws 15a instead, co-operate with the shaped profile 35 integral with the respective actuating rod 28 and being positioned in the opening step along the concave segment 37, follow the entire concave segment 37 and then the rectilinear segment 36 until closing when they reach the rectilinear segment 38. Subsequently, the shaped portion 27 further advances until the rectilinear segments 36 impact with the planar surfaces 33 achieving the locking of the jaws 15a and actuating the spring assembly 31.
- the concave segment 37 locally a slope relative to the upper axis A with respect to the angle ⁇ , allowing a shorter closing time of the jaws 15a which close pressing on the end portions of the metal wire before the jaws 15.
- the jaws 15 are actuated similarly to the manner described above, but following the guide surface 34 and during the closing phase the projection 56 is coupled with a conjugated seat borne by a grip portion 25 opposite to the grip portion 25 having the projection 56 radially locking the segment in the radial direction.
- the jaws 15 close pressing on the metal wire after the jaws 15a, but radially retain the wire already when they are closing, whilst the jaws 15a retain the end portions of the wire only when the respective shaped portion 27 abuts against the actuating portions 26.
- the guide surface 34 and the shaped profile 35 are therefore studied to convert the long and relatively slow travel of the actuating rods 28 actuating by the cam 50 into rapid and shorter displacements of the jaws 15, 15a.
- the jaws 15a can be actuated independently from the jaws 15 to lock more rapidly the two ends which in case of excessively slow closure could escape, requiring the idling of the machine for maintenance purposes.
- the early closure of the jaws 15a stably secures the wire segment and makes more reliable the subsequent grip by the jaws 15, enhancing the precision of the subsequent work processes.
- both the guide surfaces 34 and the shaped profile 35 are dimensioned to obtain a rapid closure reducing the slopes of the rolling surfaces 61, 62 and thus minimising wear.
- the shaped portions 27 can be worked more easily and are less costly than the disk 50 and are easily replaceable enabling to correct any geometric inaccuracies of the guide walls 52 by acting on the geometry of the profile, which can differ from the one described to obtain other laws of motion.
- the choice of appropriate geometry of the rolling surfaces 60, 61, 62 respectively of the guide walls and grooves 51, 52, 55 allows reliably to reach particularly low elongation values, enabling to use various types of metal wires suitable for plastic deformation work processes without breaks.

- During an initial step of the productive process, the metal wire is automatically sheared and positioned at the pincers which close gripping it or retaining in an initial circular position so that respective ends are superposed and maintained tight by a single pincer.
- Subsequently, the linear actuators and the pincers move towards the origin of the axes in co-ordinated way, obtaining a cross-shaped body that constitutes the starting semi-finished product for the manufacture of the reticular body.

- According to the present invention, a device is provided for the manufacture of semi-finished products made of metal wire, as defined in claim 1.
- For a better understanding of the present invention, a preferred embodiment shall now be described purely by way of non limiting example and with reference to the accompanying drawings, in which:
- Figure 1 is a partial front view of an embodiment of the device according to the present invention;
- Figure 2 is an axonometric view of a cage for closing a bottle containing sparkling drinks;
- Figure 3 is a partial section according to the line III-III of Figure 1;
- Figure 4 schematically shows a detail of the device of Figure 1 in a first and a second position; and
- Figures 5 and 6 respectively show enlarged details of the device of Figure 1;
- In Figure 1, the reference number 1 globally designates a device for the manufacture of semi-finished products made of metal wire, particularly for the manufacture of a
reticular body 2 of a cage 3 further comprising a retention ring 4 connected to thereticular body 2 to close a cap of a body containing sparkling drinks. - In particular, the reticular body 2 (Figure 2) is obtained from a single segment of metal wire and comprises four equidistant uprights 5 obtained by twisting the metal wire and connected to each other by respective
curvilinear segments 6 globally delimiting a circular profile 7 closed substantially perpendicular to the uprights 5. - The
reticular body 2 is obtained by means of the device 1, comprising afixed support 8, fourpincer assemblies 9 movable on thefixed support 8 along respective orthogonal axes A having anorigin 10 and four tappetlinear actuators 11 movable on thefixed support 8 along respective axes B positioned coplanar to and along the bisectors of the axes A. - Each
pincer assembly 9 comprises agearwheel element 12 rigidly connected to thefixed support 8, aslide 13 movable on thefixed support 8 along the axis A, amandrel 14 supported rotatably around the axis A by theslide 13 and a pair of jaws of thetype pincer assembly 9 respectively grips a single portion of metal wire or two ends of the segment. Both types ofjaws mandrel 14 towards theorigin 10 and maintained in an open position by anannular spring 16. - In particular (Figure 3), the
gearwheel element 12 supports, freely rotatable around the axis A, ashaft 17 comprising at opposite ends abevel pinion 18 andgrooved portion 19 engaging in a corresponding coaxialgrooved slot 20 borne by themandrel 14 and open at the opposite part with respect to thejaws - Each
pinion 18 is connected to the twopinions 18 of theadjacent pincer assemblies 9 thanks torespective transmission shafts 21 comprising a pair ofend bevel gears 22 meshing with therelated pinions 18 and globally forming a closedgear transmission 23 driven by anintermittent motor unit 24 connected to one of thetransmission shafts 21 to command the simultaneous rotary motion of thejaws - The
jaws respective grip portions 25 oriented towards theorigin 10 and actuatingportions 26 positioned at the opposite part of thegrip portions 25 relative to the hinge and superficially co-operating with an end shapedportion 27 connected in detachable way to a respective actuatingtappet rod 28 movable along the axis A and slidable inguide holes 29 having the axis A and borne respectively by themandrel 14 and by theshaft 17. - Each actuating
rod 28 is connected in freely rotatable way around the axis A on aslide support 30 comprising aspring assembly 31 to dampen the impacts in a direction parallel to the axis A. - In particular (Figure 4), each
actuating portion 26 has anend projection 32 maintained in contact with theshaped portion 27 of the actuatingrod 28 by the action of theannular spring 16 and a pair ofplanar surfaces 33 which convert towards theorigin 10 starting from theend projection 32 and are made of wear-resistant material. - The shaped portion 27 (Figure 6) has a pair of
planar guide surfaces 34 defining a respective angle α relative to the axis A to impose the law for opening and closing thejaws 15. - However, the
shaped portion 27 of thepincer assembly 9 comprising thejaws 15a, i.e. the one which grips the ends of the segment of metal wire, has, at the guide surfaces, 34 a shaped profile 35 (Figure 5) having starting from an opposite end to theactuating rod 28, a first and a secondrectilinear segment 36 inclined by the angle α relative to the axis A, aconcave segment 37 intermediate between therectilinear segments 36 and a lastlateral segment 38 parallel to the axis A and defining a lateral flank of theguide surface 34. - The actuation of the movable members along the axes A and B, i.e. of the
linear actuators 11, of theslides 13 and of the actuatingrods 28 is achieved by means of a desmodromic cam device comprising a disk 50 (Figure 3) connected to thefixed support 8 slidably around an axis C passing through theorigin 10 perpendicularly to the axes A and B and havingguide walls linear actuators 11 and theslides 13. Theguide walls rolling surfaces rollers 54a each borne by the respectivelinear actuators 11 and by therespective slides 13. - In particular, both the
roller 53 and therollers 54a are positioned at opposite parts of therespective guide walls rolling surfaces respective walls - Moreover, the
disk 50 has aguide groove 55 circumferentially obtained in theguide wall 52 and having a pair ofrolling surfaces 62 facing each other and co-operating with four pairs ofpulleys 54b having respective axes, parallel to each other and integral with therespective slide supports 30. - The
guide walls guide grooves 55 are axially symmetrically having identical sectors every 90° and theslides 13 of thepincer assemblies 9 and thelinear actuators 11 are positioned equidistant with respect to the axis C. - In particular, the
rolling surfaces rolling surface 60 is obtained similarly in relation to thesurface 61 considering that, in the instants in which thelinear actuators 11 move simultaneously with theslides 13, the segments of therolling surfaces 60 must be offset in phase by 45° from the corresponding segments of therolling surfaces 61. - The operation of the device 1 is as follows.
- The
disk 50 is driven by a motor member not shown herein, rotating at constant speed around the axis C and the guide walls andgrooves linear actuators 11 and the fourslides 13 of thepincer assemblies 9 since they are axially symmetrical and have four identical angular sectors and theactuators 11 and thepincer assemblies 9 are angularly equidistant. - The cross-shaped body of the
reticular body 2 is obtained starting from a step in which therollers grip portions 25 according to a circular trace. - Subsequently, respective descending segments of the
rolling surfaces 62 move the actuatingrods 28 relative to therespective slides 13 towards theorigin 10 closing thejaws slides 13 travelling a shorter run than thelinear actuators 11. - In this way the metal wire is bent forming the cross-shaped body in a plane that is perpendicular to the axis C after defining in continuous way a succession of closed intermediate geometric figures having rectilinear sides and rounded bending vertices both at respective junction portions between
arched segments 6 and uprights 5 and atrespective bending projections 56 exiting perpendicularly to the respective axis A from thegrip portions 25 of therespective jaws - In particular, the vertices rounded at the
jaws bending projections 56 and the perimeter of the intermediate geometric figures can be calculated instant by instant based on the positions of thepincer assemblies 9 and of thelinear actuators 11. - Consequently, the profiles of the
rolling surfaces - Once the
linear actuators 11 have reached a respective radial end stop towards theorigin 10, dampingheads 59 supported by the respectivelinear actuators 11 abut against apivot 60 of axis C and thetransmission 23 simultaneously actuates the fourmandrels 14 which, rotating around the respective axes A, twist the wire obtaining the uprights 5. - Lastly, the
jaws pincer assemblies 9 and theactuators 11 move away from the axis C returning to the initial position. - The law of motion along the axes A, B of the
slides 13 and of thelinear actuators 11 is defined directly by therespective rollers respective guide walls jaws guide groove 55 and by the law of motion defined by theguide surface 34 of theshaped portion 27 borne by the actuatingrods 28. - In particular, the
rollers 54b impose point by point to the respective actuatingrods 28 the identical displacements defined by identical radial dimensions every 90 degrees on therolling surfaces 62 actuating thejaws 15 together with therespective guide surfaces 34. - The
jaws 15a, instead, co-operate with theshaped profile 35 integral with the respective actuatingrod 28 and being positioned in the opening step along theconcave segment 37, follow the entireconcave segment 37 and then therectilinear segment 36 until closing when they reach therectilinear segment 38. Subsequently, theshaped portion 27 further advances until therectilinear segments 36 impact with theplanar surfaces 33 achieving the locking of thejaws 15a and actuating thespring assembly 31. - In particular, the
concave segment 37 locally a slope relative to the upper axis A with respect to the angle α, allowing a shorter closing time of thejaws 15a which close pressing on the end portions of the metal wire before thejaws 15. - The
jaws 15 are actuated similarly to the manner described above, but following theguide surface 34 and during the closing phase theprojection 56 is coupled with a conjugated seat borne by agrip portion 25 opposite to thegrip portion 25 having theprojection 56 radially locking the segment in the radial direction. - In this way, the
jaws 15 close pressing on the metal wire after thejaws 15a, but radially retain the wire already when they are closing, whilst thejaws 15a retain the end portions of the wire only when the respective shapedportion 27 abuts against the actuatingportions 26. - Moreover, the
guide surface 34 and theshaped profile 35 are therefore studied to convert the long and relatively slow travel of the actuatingrods 28 actuating by thecam 50 into rapid and shorter displacements of thejaws - From an examination of the characteristics of the device according to the present invention, the advantages it allows to achieve are readily apparent.
- In particular, the
jaws 15a can be actuated independently from thejaws 15 to lock more rapidly the two ends which in case of excessively slow closure could escape, requiring the idling of the machine for maintenance purposes. - Moreover, the early closure of the
jaws 15a stably secures the wire segment and makes more reliable the subsequent grip by thejaws 15, enhancing the precision of the subsequent work processes. - The use of a
single disk cam 50 to actuate all members in alternating motion along the axes A and B allows to make very precise the phase offsets of the individual operations performed by the device 1 allowing to raise the production rate. - Use of a
common cam 50 and the requirement for different laws of motion for thejaws shaped portions 27 which are able to modify the common law of motion imposed by thedisk cam 50 having respectively guidesurfaces 34 and shapedprofiles 35 differing from each other. - Moreover, both the
guide surfaces 34 and theshaped profile 35 are dimensioned to obtain a rapid closure reducing the slopes of therolling surfaces - The
shaped portions 27 can be worked more easily and are less costly than thedisk 50 and are easily replaceable enabling to correct any geometric inaccuracies of theguide walls 52 by acting on the geometry of the profile, which can differ from the one described to obtain other laws of motion. - Moreover, the choice of appropriate geometry of the
rolling surfaces grooves - Moreover, it is clear that the device described and illustrated herein can be subject to modifications and variants without thereby departing from the scope of protection of the present invention, as defined in the accompanying claims.
