Definitions

  • the present invention relates to a grinding tool according to the preamble of claim 1.
  • abrasives are for example in sanding papers with different grain sizes or Grinding flaps.
  • a disk grinding tool is now known from DE 24 11 749, in which the abrasives are perpendicular to the plate-shaped Base body standing radially from the axis of rotation Grinding flaps arranged facing outwards are.
  • the grinding flaps are regularly separated spaced either individually or as packages in the base body arranged, the grinding flaps on one side are coated with a granular abrasive.
  • On such a tool is only suitable for the occasional Use and only for editing smaller ones Area because this arrangement of the grinding flaps on the one hand lead to an irregular micrograph and on the other hand wear the grinding flaps very quickly and that Tool only has a short service life.
  • the object of the present invention was now to Grinding tool of the type mentioned with elastic intermediate elements spaced-apart grinding flaps in this regard to improve that grinding behavior continuously remains constant over the service life and one longer service life, i.e. a longer service life of the Tool can be achieved.
  • this object is achieved by a grinding tool solved with the features of claim 1.
  • the elastic intermediate element is preferably a fleece which is together with the wear of the free, machining Lamellar tip also a large wear is subject and therefore its length in operation parallel to the grinding flap is thereby ensured the thin-walled, additional separating element advantageously for the tile in the area of the working side of the Grinding flap is not subject to wear and thus has the same stability as the grinding flap self.
  • the separating element is either radial Direction with different wear resistance is executed, or two separating elements with different Wear resistance can be arranged one behind the other, this effect is intensified, but the Reduction of the length of the elastic element, preferably des Flieses, in operation together with the grinding flap not hindered because of the wear-resistant separating element is also exposed to higher wear.
  • This arrangement of the separating elements according to the invention is suitable now both for grinding tools with radial arrangement the grinding flaps in relation to a cylindrical tool body as well as for the vertically protruding arrangement the grinding flaps from a plate-shaped base body.
  • Figure 1 is the side view of an inventive Grinding tool 1 as a disc grinding tool with grinding flaps 2 shown.
  • the grinding flaps 2 are radial with respect to the grinding tool axis 3, perpendicular to the tool body 4 arranged upright.
  • At a constant distance between the individual grinding flaps 2 are between the grinding flaps 2, for example two intermediate elements 6 and 5 arranged.
  • the better clarity is for the sake of this and the following Figure only one on the right half of the figure Grinding flap 2 is shown.
  • the first intermediate element 6 now consists according to the invention made of a pressure-elastic material, preferably one Flies, and comes against that not coated with abrasive Side 2 'of the slat 2 in the stop. Between this intermediate element 6 and that coated with abrasive Side 2 '' of slat 2 is now another Intermediate element 5 arranged.
  • This intermediate element 5 is preferably made of a plastic and has a good bendability, but has compared to the Intermediate element 6 has a higher wear resistance.
  • This arrangement advantageously results in wear behavior the intermediate elements 6 respectively. 5 in operation the grinding tool 1 optimally used and a homogeneous Support achieved without any disruptive influence on the micrograph.
  • the free ends of the slats are also in operation 2 worn and are constantly shortening. By the relative high wear resistance of the intermediate elements 6 this also shortens and hinders this process therefore the grinding effect of the lamellae 2 is not.
  • the other intermediate elements 5 prevent early Wear of the first intermediate elements 6 near the tool body Area through the abrasive Side 2 '' of the slats 2 in operation, which the Support effect already impaired after a short operating time and with it a continuously deteriorating micrograph caused.
  • the length of the intermediate element 6 is preferably such that that they are in new condition close to the free ones Reach the ends of the slats 2. In operation it turns out then the length practically by the wear on, but the run-in phase is kept very small resp. it is advantageous to have a homogeneous, constant grinding pattern achieved.
  • the other intermediate elements 5, however, are preferably designed to be significantly shorter, for example, they are approximately 250% to 625% of the length of the slats 2, or can be designed even shorter. So that the tool 1 can be used until the Slats 2 together with the first intermediate elements 6 to have worn close to the end of the intermediate elements 5, which is an extension compared to conventional tools 1 means the service life of the tool.
  • Figure 4 is a longitudinal section similar to Figure 2 in one alternative embodiment shown.
  • the wear resistance of this intermediate layer 5 ' is advantageously set in such a way resp. chosen that in the operation of the tool 1 itself this intermediate layer 5 'when the slats 2 and Intermediate elements 6 shortened respectively. worn out.
  • FIG. 5 Another preferred alternative embodiment is finally shown in Figure 5 in longitudinal section.
  • the further intermediate element 5 points in the radial direction, i.e. towards the free end of the lamella 2, different Texture in relation to wear resistance.
  • the intermediate element 5 has a first, Area 7 close to the tool body, which has a high wear resistance owns, and a subsequent area 8, which has a lower wear resistance, and how the intermediate layer 5 'in Figure 4 in operation worn together with the free end of the lamella 2.
  • a carrier material for the grinding flaps 2 can preferably Natural or plastic fibers are used, which becomes a fabric as a support for that on one side arranged abrasives are processed.
  • the fabric structure is preferably used in such a way that chain and weft of the fabric are oriented so that the Weft threads of the fabric essentially vertical or in run at an angle or arc to the grinding plane and the warp threads substantially parallel to the grinding plane run. This makes it practically fray-free Wear of the grinding flaps 2 guaranteed.
  • FIG. 6 is a schematic view of an alternative, illustrated grinding tool.
  • the Grinding tool 1 has a cylindrical base clamping body 11 with drive shaft 12 on and radially thereafter externally protruding, sheet-shaped grinding flaps 2. Between the grinding flaps 2 are at least two intermediate elements 6 and 5 arranged as before described.
  • the grinding tool 1 is driven by a motor Drive axis 12 set in rotation and then tangential brought up to a workpiece to be machined.
  • the grinding tool 1 be set up stationary and the workpiece to be machined, for example by means of a gripper arm, which can be numerically controlled, brought tangentially to the rotating grinding tool 1 become.
  • FIG 7 is a partial view of some grinding lamellae 2 shown.
  • the grinding flaps 2 have here, for example a substantially rectangular shape on and are essentially related in the radial direction extending to the drive axis 12 of the grinding tool 1 Slots 15, 16.
  • the slots 15, 16 have, for example a rectangular shape.
  • the against the free Slots 15 arranged at the end of the grinding flaps 2 preferably extend to the free edge of the grinding flaps 2, i.e. there are slits open to the outside.
  • the further slots located inwards against the axis of rotation 12 16 are arranged such that their upper edges 16 'opposite the lower edges 15 'of the slots 15 offset overlapping are arranged.
  • This configuration of the grinding flaps 2 on the one hand created a coherent abrasive 1, whose free edge through the slots 15, respectively. 16 in each other flags that can be deflected practically independently and thus forms a flexible grinding edge, which also strongly shaped, three-dimensional contours of those to be machined Workpieces can follow.
  • the intermediate elements 6 and 5 is advantageously a good, homogeneous Grinding effect achieved without excessive pressure, which is why also workpieces made of relatively soft material, such as wood, can be worked without that irregular or excessive material removal through the grinding flaps 2 would cause.
  • the grinding flaps 2 are in operation when they hit the workpiece to be machined against the direction of drive rotation deflected resp. pushed away. It has now been shown that by the preferred arrangement of the slots 15, 16 in the crossed, overlapping direction of successive grinding lamellae 2 each Edge sections of each grinding flap 2 advantageously nestle together and practically a homogeneous grinding plane form.
