Definitions

  • the present invention relates to a machining device for a machine for working wood or a similar material, in the form of elongated pieces, for example of rectangular section.
  • the invention aims in particular to improve the machining in a single pass of two or more faces of the same piece of wood.
  • the conventional device for machining a face of a piece of wood or similar material is composed of a tool-holder spindle mounted in rotation, on which is engaged a tool having a machining surface of revolution around the spindle axis.
  • the object of the present invention is to create a device for machining pieces of wood allowing simultaneous machining of at least two perpendicular faces of a piece of wood.
  • the device according to the invention consists in mounting on the tool-holder spindle, comprising a first tool having a surface for machining of revolution around the axis of the spindle, a second tool in contact with the first tool and having a surface of machining of revolution.
  • the machining surface of the second tool is shaped to machine a face perpendicular to the face machined by the first tool.
  • the device according to the invention therefore has the advantage of simultaneously machining two perpendicular faces of the same piece of elongated wood.
  • the invention therefore makes it possible to save substantial time for the machining of pieces of wood.
  • the device according to the invention also makes it possible to divide by two the number of tool-holder spindles used in the conventional method for machining two perpendicular faces. It is therefore of economic interest by reducing the number of rotating spindles on the same machine.
  • the first tool engaged on the tool-holder spindle is of generally cylindrical shape, the axis of which coincides with that of the spindle and the second tool has a general shape of cutter whose diameter is higher than that of the first tool.
  • the device thus simultaneously allows the horizontal dressing or planing of one face and the vertical dressing of another face perpendicular to the first.
  • a cutting cutter comprising on its side opposite to the first tool, shredding teeth arranged on a surface of revolution coaxial with said cutter.
  • shredding teeth arranged on a surface of revolution coaxial with said cutter.
  • the first and second tools have a generally conical shape machining surface whose vertices are substantially coincident, the two surfaces form an angle substantially equal to 90 ° between them.
  • This device simultaneously allows the planing of two perpendicular faces of the same piece of wood, more particularly of substantially square section.
  • the invention also relates to a machine for the implementation of this device which comprises two machining devices according to the invention whose spindles are spaced from one another, the position of the two tools on one pins being inverted from their position on the other pin.
  • the machine according to the invention involving only two rotating tool-holder spindles, thus makes it possible to machine in a single pass the four faces of the same piece of wood.
  • the device 17 consists of a tool-holder spindle 14 capable of being driven in rotation, on which are mounted two tools 11 and 12 coupled and axially tightened on the holder spindle tool 14 by a nut 16.
  • the device 17 thus makes it possible to machine simultaneously two perpendicular faces 18 and 20 of the same piece of wood 15 of rectangular section.
  • the first tool 11 makes it possible to carry out the horizontal dressing of the lower face 18 of the piece of wood 15, as shown in FIG. 2 and the second tool 12 makes it possible to carry out the vertical dressing of a face perpendicular 20 to the lower face 18 of the piece of wood 15.
  • the coupling of the first tool 11 and the second tool 12 engaged on the tool-holder spindle 14 can be achieved by simple tightening by means of a nut 16. This tightening is sufficient for the machining tools 11 and 12 to be integral in rotation, the cutting force being of little importance given the tenderness of the material to be machined.
  • the tools 11 and 12 can also be made integral with each other by an axial interlocking system or by means of screws.
  • the first tool 11A of generally cylindrical shape may comprise, according to FIG. 3, a series of projecting blades 30 extending along the generatrices of the cylinder whose axis coincides with the axis of the tool-holder spindle 14.
  • the blades 30 are sharpenable and made of hardened steel.
  • the tool 11B may also consist of a series of projecting carbide knives 32, offset from one another.
  • the staggered arrangement of the knives 32 makes it possible to reduce the noise level during machining by avoiding brutal compression-decompression of the air between the blades and the surface to be machined, sources of whistling.
  • the tool 11C according to FIG. 5 also makes it possible to reduce the noise during machining thanks to the arrangement of the carbide teeth 34 following a helix coaxial with the cylinder of the tool 11C.
  • the second tool 120 mounted on the tool-holder spindle 14 is a cutting cutter, for example with a diameter of approximately 280 mm and a width adapted to the thickness of the wood. to eliminate.
  • the milling cutter 12A may include brazed pellets 31 of hardened steel or carbide arranged radially in notches 31a regularly distributed over the circumference of the milling cutter.
  • the cutter 12B carries carbide knives 33.
  • the second tool 12C is associated with a shredder 13 placed on its side opposite to the first tool 11C.
  • the shredding teeth 35 of the shredder 13 are arranged on a surface of revolution 36 coaxial with the milling cutter 12C. These shredding teeth 35 make it possible to reduce the strip of wood cut by the cutter 12C into chips.
  • the machine according to the invention shown diagrammatically in FIGS. 6 and 7, comprises two devices 17, 17A, the position of the tools 11 and 12 on one of the tool-holder spindles 14 being reversed relative to their position on the other spindle 14.
  • the two devices 17, 17A arranged in parallel, are offset in the direction of movement F of the piece of wood 15 on the machine.
  • One of the devices 17A placed downstream from the other device 17 according to the direction of advance of the workpiece 15, can be adjusted along a vertical axis in order to modify the thickness of the piece of wood 15 machined and along a horizontal axis in order to modify the width of the piece of wood 15.
  • the machine represented in FIGS. 6 and 7 thus makes it possible to machine simultaneously in a single pass the four faces of a piece of wood 15.
  • the piece of rough sawn wood 15, represented in FIG. 8A is introduced into the machine resting on its horizontal guide table and is machined on two perpendicular faces 18 and 20 by the first device 17.
  • the piece of wood 15 partly machined, in accordance with FIG. 8B, is then machined by the second device 17A on both other faces 19 and 21.
  • the piece of wood 15 is thus machined on its four faces, as shown in FIG. 8C, in a single pass.
  • the machine according to the invention therefore considerably reduces the number of manipulations required for the machining of four faces of the same piece of wood. It therefore makes it possible to facilitate the work of the manipulator and to save significant time during machining and thereby reduce machining costs.
  • the invention also makes it possible to considerably simplify the machine and therefore to reduce its cost.
  • one or both tools of the same machining device could be adapted to machine a face in a non-planar, but profiled manner, to produce moldings or ribs.
