Definitions

  • This invention relates to a swarf collection device and has been devised particularly though not solely for collecting swarf from a high speed milling tool adapted to machine workpieces having a variety of different profiles.
  • the swarf can build up around the tool, the workpiece and the datum faces used to hold the workpiece. This build up can cause;
  • the speed with which the chips leave the tool can be in excess of lOm/sec.
  • a shroud which surrounds the cutting area.
  • a suction device is then connected with the region defined by the shroud to suck the swarf chips away.
  • the shroud may be formed by a curtain of air
  • the present invention therefore provides an apparatus for collecting swarf from a machine tool operation, said apparatus comprising a chamber positioned in close proximity to the machine tool and arranged to substantially surround the machine tool in use, an aperture through the chamber configured such that the machine tool can engage a work surface through the aperture, and pneumatic conveying means communicating with the chamber to suck swarf from the chamber; wherein a flexible skirt is provided that extends from the aperture and is arranged to contact the work surface when the machine tool is engaged with the work surface, at least a distal portion of the flexible skirt being generally frusto-conical in shape, tapering inwardly from a portion adjacent the periphery of the aperture toward the machine tool.
  • the term "generally frasto conical" is used herein to include relevant skirt portions that may have curved rather than straight sections, such as when formed by a slice taken
  • the flexible skirt is sized and shaped such that the free edge of the skirt does not contact the machine tool when engaged with the work surface. More
  • the flexible skirt is sized and shaped so that the free edge of the skirt cannot under any mode of vertical or horizontal deformation contact the machine tool for which it is designed.
  • the flexible skirt is provided with at least one slit positioned to facilitate passage of the skirt over discontinuities in the work surface.
  • the skirt is made of rubber or a rubber like material.
  • the chamber is provided with a nozzle adapted to direct lubricating or cooling fluids onto the machine tool.
  • Figure 1 is a cross sectional elevation of apparatus for collecting swarf from a machine tool operation according to the invention
  • Figure 2 is a similar view to Figure 1 showing the machine tool and the flexible skirt of the apparatus engaged with the workpiece.
  • the milling cutter 1 is typically used to cut a predetermined shape in a workpiece such as an aluminium extrusion 4 which may for example be part of a window frame assembly.
  • the milling cutter 1 is rotated at high r.p.m. by the machining head 2 to give a high cutting speed.
  • a chamber 5 is arranged in close proximity to the machine tool and positioned to substantially surround the machine tool 1 in use.
  • the chamber is provided with an aperture 6 positioned such that the machine tool can engage the surface 7 of the workpiece 4 through the aperture 6. This is normally achieved by lowering the machine head in a controlled fashion as shown in figure 2.
  • the chamber 5 may be of any convenient shape but typically comprises an upper wall 8 configured to surround the spindle 9 of the machine head 2 and downwardly depending side walls 10 and 11.
  • the downwardly depending side walls 10 and 11 may be made rigid in configuration and shaped so that the aperture 6 conforms to the profile of the workpiece.
  • the side walls incorporate a flexible skirt 12 which will be described further below.
  • the apparatus is further provided with pneumatic conveying means including a suction nozzle 13 communicating with the chamber 5 and arranged to suck swarf from the chamber.
  • the pneumatic conveying means may be provided in any known form so as to be suitable for conveying airborne swarf from the chamber 5 to a desired disposal point.
  • the chamber may also be provided with a lubrication spray nozzle 14 located in
  • the lubricating and cooling fluids typically comprise a liquid lubricant conveyed by compressed air through the nozzle 14.
  • the lubricating and cooling fluids typically comprise a liquid lubricant conveyed by compressed air through the nozzle 14.
  • the lower edges 15 of the flexible skirt 12 contact the upper face 7 of the workpiece causing the skirt to be deformed inwardly and upwardly as shown in figure 2.
  • This contact and deformation provides a partial sealing effect for air flow into the chamber 5, keeping air velocity high through the pneumatic conveying nozzle 13 and allowing swarf issuing from the machine tool to be sucked outwardly through nozzle 13 to the point of disposal.
  • the chamber 5 including the flexible skirt 12, acts as a chip impact barrier, so that as high speed swarf issues from the machine tool 1, it impacts upon the inner surface of the chamber, reducing the momentum of the swarf and allowing it to be conveyed away through the pneumatic conveying nozzle 13.
  • the slit is therefore typically positioned on the trailing surface of the skirt (with respect to the direction of movement of the cutting tool 1) although it is possible to provide multiple slits in the skirt 12, typically equi-spaced around the circumference of the skirt.
  • the flexible skirt 12 is made from natural rubber, or an equivalent synthetic material, but it will be appreciated that other materials
  • the skirt may also be moulded in one piece with the chamber 5 as an alternative to the separate skirt shown.
  • the skirt will be generally frusto conical as shown. However, there may be other variations that achieve the same end result such as where the skirt has a part spherical configuration or is only tapered at a distal portion adjacent the workpiece.
  • the lubricant can be pumped in pulses through the nozzle by a high pressure plunger pump, such as a pump of the type commonly used for fuel injection in internal combustion engines.
  • a high pressure plunger pump such as a pump of the type commonly used for fuel injection in internal combustion engines.
  • the vacuum supply to the pneumatic conveying nozzle 13 can also be pulsed so that the vacuum is interrupted to coincide with the supply of a pulse of lubricant through the nozzle 14.
  • swarf collecting apparatus is effective in removing swarf from the workpiece so that it does not inhibit downstream processes.
  • Use of the apparatus prevents the swarf fouling the datum faces of the workpiece clamp; improving accuracy; improves the surface finish of cuts by preventing swarf re-entering the cutting zone; and reduces the cost of removing swarf, both in terms of capital cost and recurrent labour costs. Damage to the machine tools is also prevented by inhibiting the ingress of swarf.

Abstract

L'invention concerne un appareil destiné à recueillir des copeaux lors du fonctionnement d'une machine-outil telle qu'une fraiseuse verticale (1). Cet appareil comprend une chambre (5) entourant sensiblement ladite fraiseuse et un organe d'acheminement pneumatique pourvu d'une buse (13) conçue pour aspirer les copeaux à partir de cette chambre. Cette dernière est munie d'une jupe souple (12) comprenant au moins une partie distale présentant une forme généralement tronconique et se déformant au contact de la pièce à usiner (4), ce qui confère une étanchéité partielle à la chambre et améliore l'acheminement de copeaux à partir de la chambre sans risque de contact avec la machine-outil.
