Definitions

  • the invention relates to a thread cutting device of a ring spinning or twisting spindle with a truncated cone-shaped thread cutting knife, which has on its lower edge a cutting edge formed by grinding only the outside.
  • Such a thread separating device is already known as prior art (DE 40 15 707 C2), which has a thread separating knife which is arranged between a sleeve receptacle of the spindle and a winding point serving to fix a spinning thread.
  • This thread cutting knife is designed with an edge protruding from the spindle in the radial direction and has an essentially frustoconical shape.
  • the cone area has an opening angle of 45 °, the cutting edge of, for example, 30 ° requiring a clearance angle of 15 °. Due to this special configuration, the thread cutting knives had to be ground individually.
  • the object of the present invention is to design a thread-cutting knife in a thread-cutting device of the type mentioned at the outset in such a way that it can be produced with a simple structure and at low cost.
  • This object is achieved in that the grinding surface of the cutting edge lies in a cylinder jacket and that the opening angle of the thread cutting knife is 20 ° to 30 °.
  • the bearing area in the case of a thread cutting device in which the thread cutting knife has a bearing area which can be placed on the spindle and including the truncated cone area, can be designed as a plate plane arranged at right angles to the longitudinal axis of the spindle and provided with an opening for receiving the spindle, on the outer circumference of which the Truncated cone area connects.
  • spacers for adjacent thread-cutting knives made of sheet steel can be formed in the bearing area.
  • These spacers can be, for example, knobs arranged in the bearing area, lugs present in the area of the opening or independent spacer rings lying in the bearing area of the thread-cutting knife.
  • FIG. 1 shows a thread separating device 1 in the area of a ring spinning or twisting spindle 2.
  • a sleeve 3 On the spindle 2, which is equipped in the lower section with an underwinding area 4, a sleeve 3 is shown schematically. Below this sleeve 3 there is a thread separating knife 5 under a cover 19, which is capable of a spinning thread 6 to cut, which is clamped between the underwind area 4 and the sleeve 3 and is exposed in this area.
  • Fig. 2 shows the thread cutting knife 5 according to the invention in an enlarged view, partly in section.
  • this thread separating knife 5 has a bearing area 10 which runs at right angles to the longitudinal axis A-A of the spindle.
  • This storage area 10 is provided with an opening 11 for receiving the spindle 2 and forms a horizontal plate plane.
  • a truncated cone area 12 On the outside of the bearing area 10 is a truncated cone area 12 in the form of a jacket.
  • This truncated cone area 12 is formed on the outside 7 in the form of a cylinder jacket 9, which results in a cutting edge 8 on the lower edge.
  • the outside 7 forms a grinding surface for producing the cutting edge 8. From FIG. 2 it can further be seen that between the truncated cone region 12 and the cylinder jacket 9 there is an opening angle ⁇ which is 20 ° to 30 °.
  • the bearing areas 10 of the individual thread-cutting knives 5 and 5 ' are spaced apart by spacers.
  • the height of the spacers is dimensioned such that the thread-cutting knives 5, 5 ', which are combined to form the disk package S, touch only in a partial area of the truncated cone region 12.
  • the spacers are designed as knobs 15 or 15 ′ arranged in the bearing area 10.
  • the knobs of adjacent thread cutting knives 5, 5 ' are e.g. laterally offset from each other, so that a secure resting of the knobs representing the spacers on the relevant bearing area 10 of the underlying thread cutting knife is ensured.
  • knobs 15, 15 'shown in FIG. 3 there is also the possibility according to FIG. 4 that the spacers are designed as lugs 16 arranged in the region of the opening 11, which are located on surfaces 17 and 17' of the adjacent thread cutting knife 5 and 5 'support.
  • the spacers are designed in one piece with the respective thread-cutting knife 5 or 5 'and are during the manufacture of the outer edge of the ring disk, i.e. of the truncated cone area 12 is molded in using a corresponding tool.
  • the spacers are designed as independent spacer rings 18 resting on the bearing area 10 of the thread-cutting knife 5 or 5 '. This also makes it possible to combine the individual thread-cutting knives one above the other to form a disk package S before the outer edge is ground in the truncated cone region 12.
  • this disc package S is disassembled, so that the individual thread cutting blades are available in a usable form.
