Definitions

  • ABSTRACT A device for cutting holes within the wave troughs of a corrugated tube for drainage purpose in which tool supports are geared with the waves of the tube.
  • These tube supports are in one embodiment arranged along endless chains.
  • the invention relates to a device for cutting holes within the wave troughs of a corrugated tube, especially for drainage.
  • the main object of the present invention is to provide a cutting device of simple construction which ensures the high rate of production and is applicable for corrugated tubes with helical as well as circular waves.
  • the cutting tools are made as punching tools and the tool support is provided with means for an advance synchronously to the tube.
  • the synchronism of tube and tool support makes it possible to use extremely high operating speeds and thereby to reach high outputs.
  • the punching tools each are connected to a cam follower operated by a stationary cam track.
  • the punching tools may be engaged by striker springs which are tensioned by said cam track whereas said cam track is provided with an interruption at the operating position, so that the punching tools are shooted forth by the striker springs.
  • the tool supports may be provided with tooth gearing the waves of the tube in order to obtain an exact synchronisation of the feed velocity and the advance velocity of the tool support.
  • the tool supports are arranged at endless chains and preferably at two endless chains with one of their branches opposite to one another and two tool supports facing one another to form gripping jaws enclosing and by said gearing transporting the tube.
  • jaw-like tool supports are provided with coupling means for coupling always two tool supports wherever facing one another and each of said tool supports may support tools for half the circumference of the tube.
  • FIG. 1 shows a sideview of an embodiment with a wheel-like tool support
  • FIG. 2 one of the tools used in the device of FIG. 1,
  • FIG. 3 a cutting blade of the tool of FIG. 2 in a sideand frontview
  • FIG. 4 a sideview of a second embodiment of a punching device with endless chains carrying the tool supports
  • FIG. 5 in a larger scale two of the tool supports of FIG. 4 in the operating position
  • FIG. 6 a half sideview to FIG. 5.
  • FIG. 1 is showing a disk-like or wheel-like tool support 1 in connection with the tube to be punched advancing in direction of the arrow with feed velocity.
  • the tool support 1 and tube 2 are advanced in the same direction with the same velocity v.
  • the tool support 1 at its circumference is provided with tooth 3 for gearing with the waves 4 of the corrugated tube 2.
  • the gearing of tool support 1 and tube 2 will cause synchronising positive or negative forces accelerating or retarding the advance of the tube 2 feed from the extruder. These synchronising forces may easily be absorbed by the elastic tube.
  • the tool support 1 rotates around an axle 6 which is positioned crosswise to tube 2.
  • a number of e.g. sixteen cutting tools 5 are arranged with a division T n-t over the circumference of the tool support 1, said division T corresponding to an integral multiple of the wavelength r of tube 2, so that e.g. the next cutting tool 5 will reach its operating position after an advance of three wavelengths t.
  • the cutting tools 5 are slidable within guides 13 (not shown in FIG. 1 but in FIG. 4) and are supported by cam followers 8 in the form of rolls running at stationary cam tracks 9.
  • the punching tools 5 are engaged by striker springs 10 which are tensioned by said cam track 9 whereas cam track 9 at the operating position A of the punching tools is provided with an interruption so that the punching tools are shooted forth by the striker springs 10.
  • the cutting tool 5 is retracted from tube 2 and out of the hole which it has cut in the wall of this tube because it is retained by an edge at the circumference of the tool support 1. Finally the tool 5 will return after a rotation over 360 in the position for its next cutting operation.
  • each cutting tool has two cutting edges 7 in a distance corresponding to the wavelength t of the waves 4 of tube 2.
  • the cutting edges 7,7 are formed by a fore and rear roof shaped edge of a cutting blade 11 which is arranged crosswise to the feed direction. The inclination of said roof profile is made steep enough to ensure that both cutting edges 7,7 will reach the wall of tube 2 at first with their cutting tips 7c,7d.
  • tool supports 1 may be arranged with angilar positions from to 60. Only one of the tool supports is shown in FIG. 1.
  • FIGS. 4, 5 and 6 are showing a second embodiment of a cutting device according to the invention in which the tool supports 1' are arranged at two endless chains l6, 16 with one of their branches opposite to one another, so that in the area of these parallel facing branches always two tool supports l,l' are facing one another and are forming gripping jaws enclosing the tube 2.
  • the tool supports are forming an uninterrupted file of gripping jaws e.g. a file of five pairs of jaws 1.,1.
  • the jaws 1',l are glaring by tooth 3' with the waves 4 of the tube 2.
  • Each two support I is provided with coupling means 21, 22 for coupling always two tool supports whenever facing one another.
  • Said coupling means consist of wobblers 21 and sleeves 22.
  • Each of said tool supports 1' supports cutting tools for half the circumference of tube 2 and extends over a plurality of e.g. over ten troughs of wave 4 of the tube taken along and is provided with rows of tools for producing holes within each n-th e.g. each second trough of waves.
  • rows of tools are arranged with a displacement of adjacent rows by one wavelength t.
  • each tool support 1 includes three rows of five cutting tools (compare square section B in FIG. 5).
  • the cutting tools 5 are positioned in guides 13. They are driven forth for punching operation by cam tracks 9' and are retracted into their rest position by restoring springs which engage a cross pin 14 passing a cross hole within the shaft of tool 5.
  • This cross pin 14 is a spring wire lying within a slit 15 of the tool support 1' and is assisting the action of restoring spring 10'.
  • the cam tracks 9' consist of idle rollers which are arranged in stationary supports 17.
  • the velocity of the cutting movement depends on the diameter of said idle rollers 9'; it will be high with a small diameter and lower with a larger diameter.
  • the punching work is performed on the adjacent straight branches of chains 16, 16 it is possible to obtain very high velocities even with large diameters of said idle rollers.
  • an idle roller 9' of large diameter always several e.g. three or five cutting tools are sumultaneously actuated.
  • the cutting tools extend over the outside of the tool supports 1 with simple pin-like cam followers 8'. Said slits 15 for said cross pins 14 are closed by a cover 18 with holes for the passage of cam followers 8'.
  • the tool supports 1' are provided with slits 19 for the incorporation and with bores 20 for the attachment of connecting pieces 24 for connecting the tool supports 1 to chains 16.
