Definitions

  • the invention relates to support plates for a flap disc and a Flap disc with such a support plate.
  • Flap discs consist of a support plate and attached to it Grinding blades.
  • the grinding lamellae that the bring actual material removal usually consist of commercially available Abrasives on a cotton or polyester base.
  • the grinding flaps are usually placed on the carrier plate with an epoxy resin adhesive fixed.
  • the support plate is used to rotate the grinding lamella offset and the pressure required for the grinding process by the operator via the drive machine to the grinding flaps and thus to be transferred to the workpiece to be machined.
  • the carrier plate is only of indirect importance. Another An important function of the carrier plate is to guarantee the necessary Safety of the flap disc against centrifugal breakage.
  • Flap discs are usually at a peripheral speed of 50 m / s to 80 m / s operated. The considerable mechanical effects that occur Tensions in the carrier plate make the use of a material with high strength required.
  • the bending stiffness of the carrier plates is of crucial importance.
  • the support plate bends due to the weight of the sanding flaps on it, causing the adhesive is subjected to very high mechanical loads, which ultimately leads to the tearing of the slats leads.
  • the number of glass fabrics is sufficient be chosen high.
  • the required number of fabric layers is determined thus according to the total weight of the grinding flaps on the support plate are attached. At the same time, however, the number of grinding flaps is direct proportional to the tool life. Tools with a long service life must necessarily with a variety of fabric layers, e.g. twelve layers, are manufactured to meet the required safety values to be able to.
  • the invention has for its object a support plate for a flap disc To be designed so that the carrier plate while maintaining a high security against centrifugal force breakage can be manufactured particularly cost-effectively is, and a flap disc with such a support plate to accomplish.
  • the carrier plate shows only three layers in contrast to five or more layers in the state of the art, of which only the two outer cover layers made of relatively expensive fabrics or lay, while the middle layer consists of a proportionate inexpensive fiber mat made of filler material.
  • the task of So the middle position primarily consists in the greatest possible distance between the to create two top layers that have a much higher tensile strength than the middle layer. As a rule, the middle layer is therefore thicker than the top layers.
  • the flap disc manufactured using such a support plate otherwise has the usual structure.
  • a flap disc in its basic known structure from a support plate 1 and from grinding flaps 2.
  • the support plate 1 is annular and has one Central longitudinal axis 3. It is concentric to axis 3 with an opening 4 provided for receiving on the drive shaft of a prime mover.
  • the support plate 1 also has an outer annular edge region 5 on which the grinding flaps 2 in the usual manner are attached overlapping by means of adhesive, not shown.
  • the support plate 1 in turn consists of an upper Cover layer 6, a middle layer 7 and a lower cover layer 8.
  • the upper cover layer 6 and the lower cover layer 8 either consist of a textile glass fabric 9, as shown in Fig. 2, or a textile glass fabric 10, as shown in Fig. 3.
  • Both a textile glass fabric 9 and a textile glass fabric 10 consist of parallel to each other extending warp threads 11 and also parallel to each other and perpendicular to the warp threads 11 extending weft threads 12.
  • the difference is that in the textile glass fabric 9 in the plain weave shown the weft threads 12 always alternately above and below neighboring ones Warp threads 11 are passed through, as is clearly shown in FIG. 2 is.
  • a weave other than plain weave can also be used be used.
  • fabrics 9 consist of two thread systems of warp threads 11 and weft threads 12, which in a predetermined Type of binding are crossed at right angles.
  • the warp threads 11 in one plane and the Weft threads 12 also in one plane on the warp threads 11.
  • the warp threads 11 on the one hand and the weft threads 12 on the other hand are sealed side by side, as shown in Fig. 3.
  • the warp threads 11 and the weft threads 12 can consist of glass fibers, which are pre-processed into yarn or twine. For cost reasons they expediently consist of rovings. Rovings are in the Basically, a large number of textile glass filaments combined in almost parallel with a given largely identical to each other Strand fineness.
  • the middle layer 7 consists of a fiber mat, the term Fiber mat also a fiber fleece or one by needling in the volume enlarged tissue is understood.
  • Needling of fabrics is multiplied by their volume, i.e. their thickness, for example tripled while the tensile strength increased by 50% is reduced, which - as shown at the beginning - is not important.
  • Both natural fibers e.g. Hemp or sisal
  • synthetic organic fibers e.g. Polyester or polypropylene, or textile glass fibers.
  • a textile glass fabric 9 is used for the upper cover layer 6 and for the lower cover layer 8.
  • top cover layer 6 and bottom cover layer 8 Textile glass fabric 9 Textile glass fabric 9 Textile glass fabric 9 Textile glass fabric 10 Textile glass fabric 10 Textile glass fabric 10 Textile glass fabric 9
  • FIG. 5 shows the blank 15 and the blank 17 in an exploded view each made of textile glass fabric 10.
  • the textile glass fabrics 9, textile glass fabrics 10 and the fiber mats 14 are produced and brought together so that a textile glass fabric 9th or a textile glass fabric 10 each as the upper cover layer 6 and the lower one Cover layer 8 take the middle layer 7 between them.
  • These three merged Layers 6 to 8 can be used for reasons of transport security can be sewn together using threads.
  • This layer combination or the individual layers are also impregnated with phenolic resin. Subsequently the blanks are punched from this.
  • top layer 6, middle layer 7 and bottom layer 8 is pressed and cured under pressure and temperature, so that then the glass fiber reinforced phenolic resin support plate 1 is formed is then in the usual way to a flap disc is processed further.
