  • the invention aims in particular, but not exclusively, the production of elongate wooden parts in a main axial direction, in particular axisymmetric, from long wooden bars. It can also be applied to the production of parts made of other materials, especially plastics, synthetic materials.
  • the invention is particularly applicable to the realization, from a long bar, small parts section in relation to their length. It also applies to the production of larger parts by a machining transformation of a bar of typically square section, of any length, straight or curved, into parts of axisymmetrical section: circular, oval, square, possibly. helical, etc. variable longitudinal profile and respectively straight or curved.
  • the sections made are necessarily circular, the parts must be straight.
  • the production of parts such as for example twisted table legs, is more the special machine that filming and requires several successive operations.
  • the turning of bent parts can only be achieved with the help of an expensive machining center, with long machining operations (programming, positioning of the part, machining, ...) hence a cost particularly high production.
  • One of these known devices for the manufacture of cylindrical posts, is composed of an electric motor which drives a hollow mandrel equipped with at least two blades oriented towards the center and uniformly distributed on the inside of the mandrel.

Nor does it allow variations in diameter during machining. In addition, for each new diameter, reposition the blades and often disassemble and change the chuck according to the diameter to achieve. As a result, the efficiency of said device is very low, and the shapes of the products produced are limited to cylindrical shapes.

  • the reduction mechanisms used between the axial position adjustment motor and the tool supports do not allow rapid change of radial position of the tools.
  • the present invention aims to solve the problems mentioned above, and aims in particular to provide a device for machining on straight or curved bars of any length, parts of any circular section that any asymmetric, and according to a given longitudinal profile. It also aims to allow the use of such a device for making small parts in section, and having a small footprint. It is also aimed at providing a new machining device that enables continuous, high-speed machining capable of machining very thin bars, changing profiles instantly without changing tools, and machining closer to the maintenance. of the bar, thus eliminating the inevitable vibration and buckling effects during manufacturing by turning long pieces and small relative section.

  • the rotating assembly is generally compact in order to minimize the centrifugal forces and thus reduce the weight of the rotating structures, their cost and the energy requirements necessary for their rotation.
  • a motor located mainly outside the rotating structure allows to lighten the structure and, especially in the case of high rotation speed of the plate, reduce any unwanted vibrations. If necessary, however, it will be possible to use onboard motors for driving the tools in rotation, for example via the intermediate shafts mentioned above.
  • the rotary tools in the form of discs can be grinding wheels for machining parts made of soft material, such as, for example, balsa or cork, or synthetic foams, for example polyurethane.
  • the replacement of grinding wheels by cutting tools allows the machining of softwood and / or hardwood, such as beech or Ipe, exotic wood.
  • the machining of any material is possible with ad hoc tools, the shape of the tools being determined so as to be able to make strong and rapid variations of sections according to the desired longitudinal profile.

From the exit of the guide piece, the bar is machined by the two tools 3 diametrically opposed to the main axis A1 which is also the axis of the bar. Both tools 3 are located in the same section plane located closest to the guide piece 2, which distributes the cutting forces on both sides of the bar B and limits the bending forces on it.

  • the lever 5 comprises a second arm 52, inclined relative to the first arm 51 by an angle of, for example, approximately 100 °, as can be seen figure 5 .
  • the two levers 5 are facing so as to leave free between them a space of suitable shape and dimensions, sufficient for the passage of the bar B during machining.

  • Other means of guiding in axial translation and rotational connection between the second bearing 74 and the plate 41 could also be used.
  • the plate 41 is rotated by the motor 91, for example by a belt 911, and therefore in turn rotates the second bearing 74.
  • the second bearing 74 is also connected with the plate 41 and more particularly with two rotary cams 54 carried by this plate, by reversible screw-nut systems comprising a nut 77 rigidly fixed to the second bearing 74 and a screw 76 of which the end is guided in rotation on the plate 41 and carries a said cam, so that an axial displacement of the second bearing causes a rotation of the screw and thus the cam 54.
  • the cam 54 carries a pin 541 which cooperates with a groove 521 formed in the end of the second arm 52 of the lever 5, so that a rotation of the screw 76 and the cam 54 causes a pivoting of the lever 5, and consequently a radial displacement of the tool 3.
  • the tenon 541 is an eccentric which thus makes it possible, by rotating it on itself, to adjust the pivoting position of the lever 5 with respect to the rotational position of the cam 54.

  • the rotation of the motor 92 causes the screwing or unscrewing of the toothed nut 85, and therefore its axial displacement on the rocket.
  • This displacement is transmitted to the second bearing 74, and thence, as in the first embodiment, to the reversible screw-nut systems and to the tool-carrying levers.
  • the figure 11 illustrates a variant of the control of the pivoting levers 5 by the screws 76 reversible screw-nut systems.
  • the end of the screw 76 carries a gear 58 which meshes with a toothed sector 59 made on the lever 5.

  • Such an arrangement may for example be implemented using an onboard electric motor specific to each tool, to adjust the positioning of the tools independently of one another. Care should be taken not to create excessive imbalance of the machine, limiting the speed of rotation of the tool support around the machined bar.
