Definitions

  • the invention relates to a knife carrier of a planer knife, with dowel pins arranged in a line on the knife carrier, which can be used in fitting holes made of steel strip and / or hard metal plates in such a way that the knife carrier forms a planer knife unit with the disposable knife and / or the hard metal plate , which can be used in a planing machine, the dowel pins protruding from the knife carrier by a maximum of the thickness of the disposable knife or the hard metal plate.
  • Planer knives with a knife holder are e.g. used in wood planing machines, that is, surface and thickness planing machines and carpentry planing machines, in which there are grooves in the built-in planer knife shafts for inserting the planer knife, which are held with the aid of pressure strips.
  • Dowel pins produced in this way have the disadvantage that they can be released relatively easily, which can lead to accidents. At least the setting of the planing knives is adjusted by loosening dowel pins. Since the pins have to be softer than the material of the knife carrier, they are subject to greater wear. Due to the different materials of the knife carrier and dowel pins, the entire planing knife unit can warp.
  • the object of the present invention is therefore to improve a knife carrier of a planer knife of the type mentioned in such a way that, while overcoming the disadvantages indicated above, a knife carrier is made available which is considerably simplified and improved with regard to its structure and the type of its production.
  • dowel pins are punched out or embossed from the knife carrier. This eliminates the need for separate pens. Post-processing on one of the two sides or face grinding are also unnecessary. It is no longer possible for the pins to slip or fall out. Since the entire knife carrier is made of one material, there is no premature wear of the pins against the knife carrier body. Warping of the protruding pins due to different material properties is also excluded.
  • this edge is replaced by at least two pressure pins which are punched or stamped out of the knife carrier.
  • the edge known from DE-OS 29 38 201 is used to prevent the planer knife unit from tilting when installed in the planer knife shaft. This means that it is no longer possible to insert it obliquely into the groove of the planer knife shaft.
  • the edge also serves for better support on the adjusting pins arranged in the groove.
  • the edge represents a certain mechanical protection of the lower cutting edge when using disposable turning knives, especially if the entire device is dropped once.
  • the invention is implemented particularly advantageously in a knife holder of a planer knife, with dowel pins arranged in a line on the knife holder, which can be used in fitting holes formed in disposable knives made of steel strip and / or hard metal plates in such a way that the knife holder with the disposable knife and / or the hard metal plate Form planer knife unit, which can be used in a planing machine, and wherein a longitudinal stop is formed at the lower end of the knife carrier, in such a way that the dowel pins and the stop are each formed by at least two material embossments protruding from the knife carrier.
  • a knife carrier can be produced in the simplest way and ensures safe operation of the planer knife unit in a planing machine.
  • the magnets are plastic magnets arranged in punched holes in the knife holder and are flush with the surface of the knife holder. So far the known magnets have been glued into specially designed blind holes. The manufacture of the holes for receiving the magnets by punching out, on the other hand, is much easier and can be done with the same tools perform, which are used for punching the dowel pins. In addition, not only the disposable knives are held on the knife holder but also the knife holder due to the continuous magnets when the planer knives are inserted into the planer knife shaft of a planing machine. This prevents the planer knife unit from accidentally falling out of the planer.
  • the punched holes for the magnets are expediently somewhat conical. This makes it easier to drive the magnets into the holes.
  • the manufacture of the knife carriers according to the invention becomes particularly simple if the magnets are arranged in the knife carrier in one or more of the cutouts formed by punching out the dowel or pressure pins. This eliminates the need to make additional holes for the magnets.
  • the dowel pins or pressure pins are punched or embossed out of the knife carrier body until the protruding parts correspond to the width of the disposable knives.
  • all dowel pins or pressure pins can advantageously be used simultaneously are punched or embossed. In this case, it makes sense to punch the holes for holding magnets together with the dowel or pressure pins.
  • a further development of the method according to the invention provides that after punching out the dowel or pressure pins, magnets are hammered into the resulting recesses.
  • the planer knife 1 shown in Fig. 1 consists of a knife carrier 2 and a disposable knife 3 made of strip steel, which in the embodiment shown in the drawing is a disposable turning knife with two cutting chamfers.
  • Dowel pins 4 are arranged in a line on the knife carrier 2. These are just as far from the knife carrier Mais- 2 / -gegargt or punches, such as the disposable reversible knife 3 is thick. In this one-way turning knife 3 2 fitting holes 5 are provided corresponding to the dowel pins 4 in the knife holder.
  • the one-way turning knife 3 can have a saber-shaped curvature to the right, which can be pressed out by pressing the right knife end onto the corresponding dowel pins 4, which then snap into the fitting holes 5. This ensures that the knife holder 2 with the attached disposable turning knife 3. has the same height everywhere.
  • one or more magnets 7 are provided in the knife carrier 2, which are punched in slightly conical holes are hammered into the knife carrier 2.
  • an adjusting pin 9 is inserted in a groove 8 in order to keep the planer knife 1 at the same height at all times, i.e. that all planer knives 1 used in the planer knife shaft 6 have the same projection.
  • pressure pins 10 ensure that a possible tilting of the pressure bar 11 or the planing knife 1 is prevented even with different widths of pressure bars 11.
  • these pressure pins 10, like the dowel pins 4, are produced by stamping.
  • a simplified knife carrier 12 can be used which has no pressure pins.
  • Such a simplified knife holder 1 2 is shown with an attached one-way turning knife 3 in FIG. 2.
  • the magnets 7 can, however, also be inserted into the recesses 13 which are produced during the production of the dowel pins 4 or pressure pins 10. This eliminates the need to punch additional holes for the magnets 7.
  • dowel pins 4 are aligned in a line Push pins 10 formed from the knife carrier 2 outstanding by stamping.
  • holes and / or slots can also be made in the knife carrier 2 in the same way.
  • holes in the knife carrier 2 and the disposable knife 3 for the in Fi g . 3 pressure screw 14 shown may be provided if this is guided through the pressure bar 11, the one-way turning knife 3 and the knife carrier 2 to the opposite side of the groove 8 in the planer knife shaft 6, where the pressure screw engages in a thread.
