Definitions

  • the invention relates to a roller-shaped cutting body for a cutting machine with a spaced on the surface of the cutting body and made of uniformly attached base parts len-formed clearing loading screw or clearing helix, in which a bit holder with exchangeable chisel is connected to each base part l, wherein the chisel holder is inserted with a plug-in attachment into a plug-in receptacle of the base part and is held therein by means of a pressure screw.
  • Such a cutting body is known from DE 92 11 739 U1.
  • a welding template must be made, which is positioned and fixed on the surface of the cutting body.
  • the positions of the individual base parts and their alignment on the cutting body are marked on the welding template.
  • the Basistei le can then be stopped and welded one after the other, so that the Räum-Ladesc necke or Räumplanetaryl wi rd.
  • the object of the invention is achieved in that pocket receptacles are introduced into the surface of the cutting body in uniform Tei development along the to be formed clearing loading screw or clearing helix, that the base parts le run out on their undersides in a foot, which in cross section on the Pocket recordings is coordinated, and that the base part le positioned with the foot inserted into a pocket holder and are firmly connected to this.
  • the individual base parts are forcibly placed on the cutting body and fastened to it.
  • Such a procedure for creating a cutting body is time-saving and can be carried out with great accuracy by a single person.
  • the base part le is supported with the undersides of its feet on supporting surfaces of the pocket receptacles. With such a type of support, very large forces acting normal to the surface of the cutting body can be absorbed.
  • the base part le can be inserted into the pocket receptacles up to the stop on the surface of the cutting body.
  • the base part l has, for example, a foot which is tapered in cross section. This forms a paragraph with which the base part l can easily be inserted into the pocket holders from above.
  • a simple possibility, which makes it possible to position the base part le exactly, is given in that the pocket receptacles are open at the rear in the running direction and that the base part le can be inserted in the running direction of the cutting body up to the stop on the front sides of the pocket receptacles in the running direction.
  • the base parts can be welded to the cutting body.
  • threaded receptacles are introduced into the cutting body, into which fastening screws can be inserted, which serve to fix the base part.
  • the chisels can then be very close to one another if it is provided that the base bodies are lined up in the broaching loading screw or broach. Very fine surfaces can be milled with the cutting body of a cutting machine produced in this way.
  • a space-saving design can be achieved if it is provided that the pressure screw is used as a threaded bolt end tool holder is trained. This has the additional advantage that the tool holder is protected.
  • the base parts and the tool holder are forged and tempered.
  • a base 20 with an exchangeable bit holder 30 is shown in three views.
  • the cutting body 10. Has on its surface 10 pocket receptacles 27 into which the base parts 20 are inserted with their foot 26 which is tapered in cross section.
  • the base part l 20 is supported with the underside of its foot 26 on supporting surfaces of the pocket receptacles 27.
  • the insertion movement of the base part 20 into the pocket receptacle 27 is limited by means of a stop 24 which fixes the base part 20 on its front side.
  • a weld is provided for securely fastening the base part 20 to the cutting body 10.
  • the base part l 20 has a plug-in receptacle 21 which is introduced into a shoulder 28 arranged approximately parallel to the running direction 60 of the cutting body 10.
  • a stop 32 is formed at an obtuse angle on the shoulder 28 in the running direction 60.
  • the chisel holder 30 is inserted with its plug-in projection 31 into the plug-in receptacle 21 of the base part 20.
  • a prism guide 25 is introduced, which serves to guide and receive guide surfaces 35 of the plug-in extension 31.
  • the insertion movement of the chisel holder 30 is with a stop surface facing the stop 32 of the base part 20 limited.
  • a distance 36 is formed between the shoulder 28 of the base 20 and the side of the knife holder 30 facing the shoulder 28, so that the bit holder 30 is supported only on the stop 32.
  • the plug-in extension 31 has in its rear region a V-shaped recess 37, one leg of which serves as a pressure surface 38 for a pressure screw 50.
  • the pressure screw 50 is screwed with its thread 53 into a thread receptacle of the base part 20 ', so that its pin 51 cooperates with the pressure surface 38.
  • the plug-in projection 31 is drawn into the plug-in receptacle 21 and at the same time pressed into the front prism guide 25.
  • a chisel holder 33 is inserted, which serves as a plug socket for a shank part 1 of a chisel 40.
  • an annular contact surface 39 is formed on which the bit 40 is supported with a collar 41.
  • the chisel 40 is secured against axial lifting with a clamping sleeve, not shown in the drawing.
  • a tool opening 22 is introduced into the base part 20, which provides access to the end of the chisel shank facing away from the chisel head 42. With a mandrel and a hammer, the chisel 40 can then be driven out of the chisel holder 33 from the rear of the base part 20.
  • the pressure screw 50 is formed as a headless grub screw, so that it does not protrude into the tool opening 22 and thus does not affect the tool change.
  • a tool holder 52 is inserted, for example, for receiving a hexagon socket or a gate key.
  • the base parts are fastened in a row on the surface of the cutting body 10.
  • a base part 20 is placed with its front joint 71 on a rear joint 72 of another base part 20 and fastened on the cutting body.
  • the base part l 20 is welded to the surface of the cutting body 10. But it is also conceivable to provide a screw connection.
  • Pocket receptacles 27 are formed as sac locate recesses in the surface of the cutting body 10, into which the base part 20 is inserted with its base 26.
  • the foot 26 can be tapered in its cross section compared to the base part 20. With the heel thus formed, the foot 26 is then supported on the surface of the cutting body 10.

Abstract

L'invention concerne un élément tranchant cylindrique pour une haveuse. Une vis sans fin d'abattage et de chargement ou un dispositif hélicoïdal d'abattage constitué(e) de pièces de base réparties de manière égale est disposé(e) en saillie sur la surface de l'élément tranchant (10). Un porte-outil (30) pourvu d'un trépan (40) échangeable est relié à chacune des parties de base (20). Le porte-outil (30) pourvu d'une pièce rapportée embrochable (31) est introduit dans une cavité correspondante de la pièce de base et y est maintenu au moyen d'une vis de serrage (50). On parvient à un montage rapide d'un élément tranchant (10), qui permet de positionner et de fixer de manière aisée les pièces de base (20) sur la surface de l'élément tranchant (10), du fait que des réceptacles de type godet (27), répartis de manière régulière le long de la vis sans fin d'abattage et de chargement ou du dispositif hélicoïdal à constituer, sont mis en place dans la surface de l'élément tranchant. Au niveau de leurs faces inférieures, les pièces de base (20) sortent dans un pied (26) qui est adapté en section transversale aux réceptacles de type godet (27). Les pièces de base (20) sont introduites positionnées avec le pied (26) dans un réceptacle de type godet (27) et en sont rendues solidaires.
