Definitions

  • the present invention relates to a method of deburring cut surfaces on tubes or profiles comprising the step that the cut surface is brought into contact with the periphery of a substantially circular brush rotating about a first axis.
  • the present invention also relates to an apparatus for deburring cut surfaces on tubes or profiles comprising a preferably circular brush rotary about a first axis, a guide for aligning the tube or profile, and drive means for driving the brush.
  • the present invention has for its object to devise the method intimated by way of introduction in such a manner that it may simply and rationally be applicable to tubes and profiles without the need of placing any restriction on the orientation of the cut surface in relation to the longitudinal axis of the tube or profile.
  • the present invention thus has for its object to realise a method of deburring mitred or obliquely cut tubes or profiles.
  • the present invention further relates to realising a method which is rapid and effective and may readily be automated.
  • the present invention further has for its object to devise the apparatus intimated by way of introduction such that this permits deburring of tubes or profiles irrespective of the orientation of the cut surface in relation to the longitudinal axis of the tube or profile.
  • the present invention has for its object to realise an apparatus which is well-suited for deburring obliquely cut or mitred tubes or profiles.
  • the present invention yet further has for its object to realise an apparatus which is economical to manufacture, simple to manage and efficient in operation.
  • the objects forming the basis of the present invention will be attained in respect of the method if this is characterized in that the cut surface and the brush are brought to such a mutual position that the cut surface is approximately encompassed in or is approximately parallel with a tangential plane to the brush; and that a movement is imparted to the brush about a second axis which is approximately at right angles to, or at least transversely directed to the cut surface.
  • the guide is arranged to align the tube or profile such that its cut surface is approximately encompassed in or is approximately parallel with a tangential plane to the brush; and that the power unit includes means for the movement of the brush about a second axis which is transversely directed, but preferably approximately at right angles to the cut surface.
  • the second axis extends through the cut surface, preferably through its central or middle region.
  • reference numeral 1 relates to a frame arrangement which is mounted in a machine frame such that it is pivotal about the preferably horizontal pivot axis 2 shown by broken lines.
  • the frame arrangement 1 is pivotal between a recumbent, approximately horizontal position for deburring straight cut tubes or profiles (Fig. 4), and an upwardly angled (or in an alternative embodiment downwardly angled) position for deburring obliquely cut tubes or profiles (Fig. 2).
  • the frame arrangement 1 carries a journal device 3 which, in turn, carries a retainer device 4 for a substantially cylindrical, rotary brush 5.
  • the brush 5, which preferably has bristles of steel or other metal, is rotary in relation to the retainer device 4 about a first axis of rotation 6.
  • the retainer device 4 is rotatably journalled about a second axis of rotation 7 in the journal device 3.
  • the housing of the retainer device 4 is rigidly connected to an outer drive shaft 8 which is tubular and is journalled in the journal device 3.
  • the inner drive shaft 9 extends into the retainer device 4 where there is disposed a gear arrangement by the intermediary of which the rotational movement of the inner drive shaft 9 is transmitted to the spindle 10 of the brush 5 so that rotation may thereby be imparted to the brush 5 about the first axis of rotation 6.
  • the upper end 15 on the Drawing of the inner drive shaft 9 is connected to one or more pulleys 11.
  • the pulleys 11 are, by the intermediary of belts 12, in communication with corresponding pulleys 13 on a drive motor 14 which is secured in and carried by the frame arrangement 1.
  • the drive motor 14 will hereby be drivingly connected to the brush 5 so that this may be driven in the above-intimated rotational direction about the first axis of rotation 6.
  • the upper end portion 15 of the inner drive shaft 9 has a further pulley 16 for driving a reduction mechanism 18 by the intermediary of a drive belt 17.
  • the reduction mechanism 18 drives a pulley 20 which is connected to the end portion of the outer drive shaft 8 located over the journal device 3.
  • the drive motor 14 will, in the above-described manner, be connected for driving the brush 5 about the first axis of rotation 6, but also via the reduction mechanism 18 for driving the outer drive shaft 8 and thereby for rotating the retainer device 4 and the brush 5 about the second axis of rotation 7.
  • the reduction mechanism 18 has been exemplified as a belt transmission, but may of course be designed in any other optional and appropriate manner. Naturally, the reduction mechanism 18 should be mounted on and supported by the frame arrangement 1.
  • pulleys and belts may, naturally, just as well consist of other types of transmission devices such as gear wheels, chain drive, cogged belts etc.
  • reference numeral 22 relates to a tangential plane to the brush. This tangential plane should be approximately parallel with the first axis of rotation 6.
  • reference numeral 23 relates to an end portion of the tube or profile which is to be deburred. It will be apparent from the Figure that the end portion is not cut straight across but is mitred or obliquely cut so that the cut surface makes an angle deviating from 90° to the longitudinal direction of the tube or profile.
  • a guide (not specified in great detail on the Drawings), through which the tube or profile may be inserted.
  • This guide is adjustable in the vertical direction in relation to the pivot axis 2, i.e. is movable in accordance with the double headed arrow 24.
  • the guide is laterally adjustable, i.e. parallel with the longitudinal direction of the pivot axis 2.
  • the guide may comprise a sleeve-shaped or tubular device which surrounds the tube or profile which is to be deburred so that the profile or the tube may be inserted therein.
  • this sleeve-shaped device may be replaceable so as to allow for adaptation to different dimensions of tubes or profiles.
  • Fig. 4 the frame arrangement 1 has been pivoted about the pivot axis 2 in a clockwise direction so that the second axis of rotation 7 is parallel with or coincides with the longitudinal direction of the tube or profile 23. In this position, the apparatus is set for deburring a tube or profile which has been straight cut.
  • the cut surface 21 of the tube or profile is located in or approximately parallel with the tangential plane 22 of the brush 5. Furthermore, the adjustment setting is such that the second axis of rotation 7 extends through the cut surface 21, preferably through its central or middle region.
  • first and second axes of rotation 6 and 7, respectively are transversely directed in relation to one another, however, preferably approximately at right angles.
  • the axes 6 and 7 suitably intersect one another at a common point.
  • the retainer device 4 and the brush 5 have been turned through approximately 90° about the second axis of rotation 7 in relation to that illustrated in Fig. 2.
  • the cut surface 21 of the tube or profile 23 lies in or parallel with the tangential plane 22 of the brush 5.
  • the second axis of rotation 7 extends through the cut surface 21, preferably through its central region. It will also be clearly apparent that the axes 6 and 7 are transversely directed and are preferably at right angles in relation to one another.
  • the method of deburring using the above-described apparatus proceeds in the following manner:
  • the angle of inclination of the frame arrangement 1 in relation to the horizontal plane 26, and thereby also the angle of inclination of the second axis of rotation 7 (see Fig. 2) is set in response to a display device which shows the inclination of the frame arrangement 1 in relation to the horizontal plane 26 and the frame or foundation of the machine. It will here be assumed that the longitudinal direction of the tube or profile 23 also lies in a horizontal plane.
  • the angle of adjustment ⁇ (Fig. 2) of the frame arrangement 1 is, in this situation, adapted in response to the angle between the longitudinal direction of the tube or profile and the direction of the cut surface 21.
  • the angle ⁇ will be 45°, while the angle ⁇ will be 0 in a straight cut tube.
  • the guide is placed in such a manner that the second axis of rotation 7 will pass through the cut surface 21, preferably as close to its centre as possible.
  • the adjustment of the guide may, here, take place in both the vertical direction (according to the arrow 24) and in the horizontal direction (in the longitudinal direction of the pivot axis 2).
  • the apparatus is set for use, whereafter the drive motor 14 may be started.
  • the brush 5 will rotate, not only about the first axis of rotation 6, but also, and preferably at lower speed, about the second axis of rotation 7.
  • the tubes or profiles 23 which are to be deburred are moved in the longitudinal direction into the guide until the cut surface 21 comes into contact with the brush 5. Once the brush 5 has completed a number of rotations about the second axis 7, the deburring operation is completed.
  • the movement of the brush 5 about the second axis of rotation 7 is to be a continuous rotational movement. According to the present invention however, this is not necessary, but instead the movement may be a stepwise rotational movement, an alternating movement and a movement in which each phase should extend reciprocally through at least 360°.
  • the frame arrangement 1 is to be pivotally secured in the foundation or frame of the machine proper and be pivotal about the pivot axis 2.
  • the angle between the second axis of rotation 7 and the longitudinal direction of the workpieces 23 which are to be deburred may be set in response to the angle of cut of the workpiece.
  • such a setting or adjustment may also be made with a fixed mounting of the frame arrangement by pivotal adjustment of the guide.
