Definitions

  • the invention relates to a device for grinding the knife of chippers according to the preamble of claim 1.
  • Such Device is known from US 4,791,760 A.
  • a big problem with such chipper is the relatively small one Service life of the knives. Due to the wear the knives already have be exchanged after a few hours of operation, i. multiple times per working shift. Installing new, sharp blades requires one special effort. The desired chip thickness results namely from the distance of the knife against the so-called wear plates, the in turn are part of the knife wreath. It follows that the Swap blunt knives against sharp knives very timely and is expensive. In particular, the personnel costs are high for this.
  • the invention has for its object to provide a device for grinding the To make knife of Zerspanem so that the grinding process more efficient can be carried out.
  • the inventor has recognized that the inventive design of the Grinding device the medium for cooling and lubrication with high Speed is introduced to the work site of the grinding device. Due to the centrifugal force of the grinding device is not only the Flow rate of the medium increases, but also the Jet pressure of the medium, so that this really all surface elements of the detected to be ground knife. In this way, the grinding process can be perform faster and more efficiently.
  • the grinding device according to the invention is also suitable to sharpen so-called clearance angle.
  • Fig. 1 shows an apparatus for grinding blades of a Zerspaners. The chipper itself is not shown here.
  • the grinding station 1 is movable on rollers 1.2 relative to the chipper, in this way that a knife basket received at the chipper and from this can be transported away to the working position of the grinding station 1.
  • Im illustrated embodiment is a knife basket 2 in the grinding station. 1 used. He rests on rollers 1.3 so that he in the grinding station 1 to his own axis can be clocked.
  • the knife basket 2 has a plurality of knife packages 3, the best can be seen from Figure 4. One sees there each a support block 3.1, a Clamp 3.2, a between these two located knife 3.3, a Clamping screw 3.4 and a wear plate 3.5.
  • the crucial element of the entire device is one Grinding device 4. This can be seen in FIG. 1, but even more precisely Fig. 2.
  • the grinding device 4 is substantially pot-shaped.
  • the grinding device 4 has a Adapter 4.1, a grinding wheel 4.2 and an attached slip ring 4.3.
  • the slip ring 4.3 is applied to a knife 2.1, the blade ground becomes.
  • the adapter 4.1 is a line 5.1 for bringing a cooling and Assigned to lubricating medium.
  • medium from a radial internal point radially outward on the cutting edge of the blade 2.1 directed.
  • a plurality of blades 5.4 are provided. These serve to increase the pressure.
  • the blades 5.4 can in the manner of Be designed pump blades.
  • the cooling and lubricating medium thus takes the following route: it passes through the line 5.1 first in the channel section 5.2. In the transition from the line 5.1 to channel section 5.2 is due to the centrifugal force a Acceleration instead, and thus an increase in pressure.
  • the medium is then substantially in directed parallel to the axis and thrown against the grinding wheel, supported by the blades 5.4
  • the device according to the invention not only for Grinding knives of a chipper, but also wear plates of a chipper, can be used.
