Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Such a device known from DE-C-22 30 767 has proven itself extremely well in practice since it enables continuous cutting of openings in corrugated tubes, specifically openings in the respective trough, with the course of the cutting edge of the respective knife on an epitrochoid the chip cut out of the outer wall of the tube is cut outwards, i.e. does not fall into the tube.
  • the known device is, however, in terms of its application for special shapes of pipes, such as. B. annular corrugated tubes, which may additionally have a foot not provided with openings, in need of improvement.
  • a comparable device is known from DE-A-2810165, which has a cutter head which is provided with helically extending webs.
  • the object of the invention is to improve the generic device in such a way that even corrugated tubes can be provided with openings in the respective trough, both a defined insertion of the slots and a removal of the cut chips being achieved with reliable transportation of the tube should.
  • the inventive design ensures that the tube is at least transported in its longitudinal direction by the cutter head, although the transverse shafts are each designed as circular rings or partial circular rings.
  • the chips cut out from the respective cutter head or cutter heads can be completely cut off by means of the scraping head, if necessary, which at the same time also contributes to the transportation of the tube.
  • the measures according to claim 2 ensure that, on the one hand, proper transport takes place despite the frictional forces acting in the sliding bed and that on the other hand, no openings are cut in the foot area.
  • the measures according to claim 3 ensure that, on the one hand, the slippage between the scraping head and the tube occurs when the scraping head is being rolled, but on the other hand that the advancing effect of the scraping head is identical to the advancing effect of the knife head (s) and, if applicable, of the transport head (s).
  • a stationary, i.e. H. non-rotating housing 1 which has a hollow hub 2 to which a protective cage 3 is fastened by means of screws 4.
  • the pot-shaped protective cage 3 is closed on its side facing away from the hollow hub 2 by means of a cover 5 which is screwed onto the protective cage 3 with screws 6.
  • the cover 5 has an inlet opening 8 concentrically with the central longitudinal axis 7 of the housing 1 for a pipe 9 to be explained further below.
  • a fixed external ring gear which is the sun gear 10 of a planetary gear
  • a hollow shaft 12 is rotatably mounted in the housing 1 by means of a ball bearing 11, onto which a drive flange 13 is screwed in a rotationally fixed manner by means of a thread 14.
  • the inner diameter of the hollow shaft 12 arranged concentrically to the axis 7 is in any case significantly larger than the outer diameter of the tube 9 fed through the hollow shaft 12.
  • pairs of planet gears 15, 16 and 17, 18 are rotatably mounted.
  • the planet gears 15, 16 are arranged concentrically to one another and rigidly connected to one another, ie they are connected in a rotationally fixed manner to a common shaft, the planet gear 15 engaging in the sun gear 10.
  • the two planet gears 17, 18 are also arranged coaxially to one another and rigidly connected to one another, ie they are also non-rotatable connected to a common shaft.
  • the planet gear 16 engages in the planet gear 17 so that the planet gear 18 is also driven.
  • the planet gear 18 engages in a drive gear 19, which in turn is rotatably mounted on a shaft 20 which is rotatably mounted in a bearing 21 in the drive flange 13.
  • a three-part cutter head 22 is fastened to the shaft 20 by means of a threaded nut 23.
  • the drive flange 13 further pairs of planet gears 15, 16 and 17, 18 are rotatably mounted, which serve to drive a scraping head 24 or to drive transport heads 25.
  • the scraping head 24 and the transport heads 25 are fastened in the same way as the cutter head 22 and approximately in a plane common to this and perpendicular to the axis 7 by means of threaded nuts 23 on shafts 20 which are mounted in bearings 21 in the drive flange 13 and which have a drive gear wheel 19 wear that engages in the associated planet gear 18.
  • the sun gear 10 and the planet gears 15 to 18 and the drive gears 19 are designed in a manner known for planetary gears in such a way that with a full rotation of the drive flange 13 according to the direction of rotation arrow 26 the shafts 20 and thus the cutter head 22, the scraping head 24 and the transport heads 25 make exactly one turn around their own axis 27.
  • the tube 9 is a so-called circular corrugated tube with a foot 28, i. H.
  • the cutter head 22 and equally the scraping head 24 and the transport heads 25 are each provided with a helical profile whose webs 31, 32, 33 engage in the troughs 30.
  • the cutter head 22, the scraping head 24 and the transport heads 25 are provided with webs 31, 32, 33 in the manner of a two-start thread, the pitch t of which therefore extends in each case over the axial extent of two webs 31, 32, 33.
  • the pitch t of the cutter head 22, the scraping head 24 and the transport heads 25 is identical and the same as the axial distance between the next but one wave crests 29 of the tube 9. That the cutter head 22, the scraping head 24 and the transport heads 25 change every full revolution of the drive flange 13 once around its own axis 27 in the direction of rotation 34 relative to the drive flange 13, the tube 9 is pushed forward by the amount of the pitch t, that is to say twice the distance between two adjacent wave crests 29 in the transport direction 35, for each revolution of the drive flange 13.
  • a slide bed 36 Arranged in the hollow shaft 12 is a slide bed 36 which is adapted to the shape of the base 28 of the tube 9 and which penetrates the inlet opening 8 in the cover 5 and is fastened thereto by means of a screw connection 37.
  • the cutter head 22 is constructed in three parts. It has a central knife carrier 39, on which knives 40 are attached, which have cutting edges 41 leading in the direction of rotation 34, which protrude beyond the webs 31. In the axial direction on both sides of this central knife carrier 39, pure web sections 42, 43 are formed. The knife carrier 39 and the two web sections 42, 43 and the knives 40 are clamped together by means of clamping screws 43a.
  • the knife 40 and the basic structure of the knife head 22 is known from DE-PS2230767.
  • water inlet openings 44 are cut into the tube 9 in a manner known in principle, in each case in the region of the wave troughs 30.
  • the web 31 of the cutter head 22 is constructed in the manner of a two-start thread, that is also the knife carrier 39 extends over two courses, corresponding to the division t, the knives 40 - as can be seen in FIG. 2 - can be arranged so that the openings 44 in two adjacent troughs 30 are not arranged on an axis-parallel line, but offset against one another are arranged.
  • the sliding bed 36 can be adjusted transversely to its longitudinal direction.
  • 45 elongated holes 46 are provided in a flange through which the screw connection 38 passes.
  • FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 essentially in that two cutter heads 22 'are provided which are diametrically opposite one another.
  • the storage and the drive correspond to that according to FIGS. 1 and 2.
  • the arrangement of two cutter heads 22 ' is possible because a normal circular corrugated tube 9' is provided with openings 44; so it is not a foot on tube 9 '. For this reason, no sliding bed is provided.
  • a scraping head 24 is provided, which likewise has no recess. Since no slide bed is provided, it is also not necessary to provide transport heads which bring about an axial advance of the tube 9 '.
  • At least one support roller 47 needs to be provided, which is not driven but is freely rotatably mounted in the drive flange 13 '.
  • the cutter heads 22 ' have four threads, that is to say they have four webs 31'. With one revolution of each cutter head 22 ', the tube 9' is thus pushed forward in the transport direction 35 by the axial distance of four webs 31 'in accordance with the division t'.
  • Both cutter heads 22 ' are of identical design, that is to say they can be interchanged. Since the knives 40 are not offset in the embodiment according to FIG. 4 compared to the embodiment according to FIG. 2, the knives 40 must therefore be mounted parallel to one another in the cutter heads 22 'at a distance of t' / 2.
  • the upper cutter head 22 ' cuts the openings 44 in the second and fourth wave troughs 30', while the lower cutter head 22 ', which is offset in the axial direction by t' / 4, cuts the openings 44 in the first and third wave troughs 30 ' .
  • the offset arrangement of the openings 44' results from the first to the second wave trough 30 'and from the third to the fourth wave trough 30'.
  • the cutting edge 41 of the knife 40 is described when a rolling circle k with a radius r rolls without slip on a leading circle K with a leading circle radius R and the distance A of the point (cutting edge 41) from the center point M of the rolling circle is greater than that Radius r of this pitch circle k.
  • the center m of the rolling circle k moves on a circular line L.
  • the epitrochoid E forms a loop which is immersed in the conducting circle K.
  • the rolling circle k is formed by the cutter head 22 'or 22, while the guide circuit K is formed by the tube 9' or 9. Each time the cutting edge 41 is immersed in the guide circuit K, i. H.
  • cutting teeth 48.1, 48.2, 48.3 ... are provided on the circumference of the scraping head 24 or 24 ', the outer radius of which is equal to Rb.
  • FIG. 7 when cutting an opening 44 - for example because the cutting edge 41 of a knife 40 becomes blunt - the chip 49 to be cut out has not been completely cut off.
  • a cutting tooth 48.1 has already passed the chip 49, the next cutting tooth 48.2 runs in the direction of the chip 49.
  • the subsequent cutting tooth 48.2 catches up with the chip 49 and cuts it off, as can be seen from FIG. 9.
  • the chip falls into the protective cage 3, where it is drawn off together with the other chips through a lower extraction opening 50.
  • a guide plate 51 is fastened to the drive flange 13, by means of which the cut chips 49 are pushed to the extraction opening 50.
  • the openings 44 widen towards the inside of the pipe 9 or 9 'by an angle ⁇ , which is particularly advantageous for drainage purposes.
  • the reason for this is that the openings 44 are cut open essentially by cutting out one chip 49 from the inside outwards.
  • the tube is slightly curved outwards in the region of a wave trough 30 or 30 ', as a result of which the plastic material of the tube is given a slightly conical, outwardly narrowing or inwardly widening cutting surface with the cutting angle ⁇ .
  • the tubes 9 and 9 ' are made of plastic in upstream corrugated tube molding machines of a known type.
  • the axes 27 and 27 'of the cutter head or 22 or 22' and the scraping head 24 or 24 'and the Tran sports heads 25 are shown in the drawing only for the sake of simplifying the drawing parallel to the axis 7 of the tube 9 or 9 '. In fact, they must be set in relation to the axis 7 in accordance with the pitch angle of the bars 31 or 31 ', 32, 33 resulting from the division t. This is achieved in that the last planet gear 18 and the associated drive gear 19 are designed as bevel gears with corresponding bevel angles. However, this measure is known and is also necessarily used in practice in the devices known from DE-PS 22 30 767.
