Definitions

  • a device for stamping apertures in the wall of a alms rawmg corrugated thermoplastic tube comprises a rotatable hollow US. Cl 83/358, nut for guiding the outer wall of the tube, and bits for stamping 83/423, 83/519, 214/338 apertures in the tube without supporting the inner wall of the Int. Cl 826d 5/16 tube during stamping from outside.
  • the bits are depressed in Field of Search 831192, the plastic material by operating cams or by a guiding groove. 193, 194, 350, 355, 357, 513, 519, 628, L83; 18/2
  • the bits are effective in the area just besides the 1; 214/338 profiled end of the nut.
  • Such a device for providing apertures in the wall of a plastic tube especially a corrugated tube for draining purposes comprises a frame with guide means for guiding the plastic tube, punching means for making apertures being mounted for radial movement, and lying outside respectively inside the tube, means for depressing said punching means which are effective without supporting means for the punching means at the inner side or outer side of the tube.
  • the guide means for the plastic tube consists of a hollow rotatable nut, connected with at least one radially inwardly movable punch provided at its end with bits for blanking out parts of the tube wall, which can cooperate with operating cams provided on a stationary ring for actuating the punches.
  • the guide means for the plastic tube consists of a hollow rotatable nut, said nut carrying a disc provided with a noncircular groove, a projection connected with the stationary punch being capable of movement in this disc.
  • FIG. 1 is a section through a device according to the invention
  • FIG. 2 is a section taken on line 11-11 in FIG. 1;
  • FIG. 3 is a modified embodiment of the device according to the invention.
  • FIG. 4 is a section taken on line IV--IV in FIG. 3.
  • FIGS. 1 and 2 Represented in FIGS. 1 and 2 is a device consisting of a frame 1 carrying a stationary ring 2 in which by means of a ball bearing 3 a rotatable nut 4 (driven by a nonrepresented motor) is secured which serves as a guide member for a relatively thin plastic tube 6 of thermoplastic, polyvinylchloride or polyethylene, being 0.2-0.6 mm. thick.
  • the inner wall 5 ofthe nut 4 has a helical profile corresponding with that of a corrugated tube 6 to be worked as shown in FIG. 1.
  • Fixedly secured on the rotatable nut 4 are punching means in the shape of a punch 8 provided with bits 7 and a head 9. Operating cams 10 on the stationary ring 2 actuate the punch 8 and drive the bits through the wall of the tube.
  • the device operates as follows. A corrugated tube 6 formed on a tube forming machine is guided in the profiled wall portion 5 of the rotatable nut 4. The rotatable nut is driven via gear wheels (not shown) by the tube forming machine, whereby a synchronous process is obtained.
  • the nut 4 with punch 8, head 9 and punching members in the shape of bits 7 rotate until the head 9 encounters an operating cam 10 whereby the punch is depressed and the bits 7 are passed through an opening in the nut 4 and an aperture is punched in the wall of the tube. It is evident that the number of apertures provided in the wall of the tube is determined by the number of operating cams 10.
  • the bits 7 are advantageously disposed in such a way that they exclusively provide apertures in the hollows of the corrugated tube, which is readily obtained by the form of the cams.
  • the punch is springloaded by a spring 11 in order to ensure the return thereof after making an aperture.
  • FIGS. 3 and 4 Represented in the FIGS. 3 and 4 is a preferred embodiment in which likewise a frame 1 is provided and a rotatable nut 4 serves as a guide member for the tube.
  • the inner wall 5 of the nut 4 has likewise a profiled surface corresponding with that of the corrugated tube to be treated.
  • This nut is connected with a disc 13 provided with a noncircular groove 12.
  • a projection 14 connected with a stationary punch 8' can move.
  • the disc 13 On rotation of the nut 4, the disc 13 will be taken along and consequently the projection 14 connected with the punch will also be guided in this groove 12. Owing to the noncircular shape of the groove 12 the punch is depressed at the location of the noncircular part 15 and the wall of the tube is perforated.
  • the profile of the nut 4 substantially ends before the working area of the bits 7.
  • the profile of the plastic tube is regular, but in certain cases, tubes having a regularly varying profile, e.g. the hollows of different depths alternating with tops of different heights, are preferred.
  • a device for forming apertures in the wall of a continuous, helically corrugated plastic tube for draining purposes comprising a frame, a hollow rotatable nut axially fixed in said frame and threadably engaged with said tube to guidably advance the tube through the frame as the nut rotates, punching means for making apertures in the tube, said punching means being mounted for radial movement on one side of the wall of the tube, said nut being in threadable engagement with the tube in the region of the punch means, and means associated with said nut for depressing said punching means in accordance with the rotation of said nut to form the apertures in the tube without supporting means for the punching means at the other side of the wall of the tube.
  • said punching means includes at least one radially inwardly movable punch slidably supported in said nut intermediate the ends thereof, said nut being provided at the inner end thereof with a bit for stamping out part of the tube wall to form said apertures, and a stationary ring with operating cam means thereon for actuating the punch.
  • said means for depressing said punching means comprising a disc rotatably secured to said nut and provided with a noncircular groove, and a projection connected with the punching means and displaceable in said noncircular groove during rotation of said nut to actuate the punching means as the nut and disc rotate.
  • said punching means comprises a plurality of radial punches slidably supported in said frame and arranged therein in circumferentially spaced relation, each punch including one of said projections which is engaged in the noncircular groove.
