Definitions

  • the invention relates to a flap disc according to the preamble of claim 1.
  • DE 35 25 620 is a flap disc known, along which along the peripheral zone a circular disk-shaped flexible base plate in radial slots of the peripheral zone grinding lamellae each other arranged overlapping like roof tiles and unsolvable are attached.
  • a circular disk-shaped flexible base plate in radial slots of the peripheral zone grinding lamellae each other arranged overlapping like roof tiles and unsolvable are attached.
  • Base plate designed as a partial disc in its peripheral zone radial slots are present that lead to gill-like Openings are extended into which grinding lamellas are trapped.
  • DE-GM 88 04 148.4 describes a flap disc, which consists of a metallic support plate consists of an outer ring on the fan forming grinding flaps are glued on.
  • the part of the backing plate which carries grinding flaps is frustoconical bent. This is said to be ergonomic created favorable shape and the strength against Centrifugal stress can be increased.
  • DE 38 39 238 discloses a flap disc with a base plate, with the fan-shaped an outer ring of lamellar roof tiles are glued across.
  • the base plate is preferred formed as a metal disc in which Breakthroughs are located, which are preferably round. This Holes are used to allow the adhesive to flow through Back. One attached to the back of the plate Lowering increases the hold of the adhesive. At the same time, the plate has several in the clamping area Notches on the self-locking when tightened ensure against loosening of the nut. Through this Training should create a basic plate, which high operational reliability with a simple production guaranteed.
  • DE 40 20 461 is a flap grinding tool known, which has a support plate with a fastener for placement on a prime mover is provided, as well as with a grinding wheel, a circular disk-shaped, detachable on Support plate attachable carrier and arranged thereon Has abrasives.
  • the carrier consists of a flexible fabric.
  • Lanyard between the Carrier and the support plate is a self-adhesive, Detachable, large surface fastener.
  • the outside diameter of the carrier and the one arranged thereon Grinding flaps are larger than the outside diameter one depending on the progressive degree of wear of the grinding flaps selected and in its diameter adapted to the respective degree of wear Support plate, which with a centric, Pin on the grinding wheel side for a central perforation is provided in the carrier.
  • DE 195 43 597 is a flap disc known for hand grinders, consisting of a round carrier disc with a centrally arranged Device for attachment to a hand grinder and overlapping like a fan on the carrier disc attached grinding flaps that extend up to extend or over the outer edge of the carrier disk these protrude.
  • the surfaces of the grinding flaps serve as a grinding surface.
  • the radially outside Narrow sides of the grinding flaps form the scope of the Flap disc.
  • At least the narrow sides of the Sanding flaps are made with a hardening binder provided, the material-removing on the to be processed Object acts and extends to the grinding surface extends. This training is intended to be a flap disc be created, even with frequent Use in areas that are difficult to access such as angles, Corners or the like has a long service life.
  • the object of the present invention is in a flap disc of the type mentioned Type in such a way that the grinding effect with reduced Improved material and manufacturing costs becomes.
  • the invention proposes for the lamellae Flap disc two different types of flaps the first slats, consisting of a pad, one attached to it Basic bond layer and one on the basic bond layer Spreading layer made of abrasive grain and one applied to the abrasive grain scattering layer Top layer, and on the other second slats, consisting from one pad and only one on the pad applied layer with abrasive substances.
  • the training according to the invention has the advantage that the slats overall easier and cheaper can be produced, which means the flap disc overall becomes cheaper.
  • FIG. 1 shows a flap disc 2 with a support plate 4, which has a central through hole 6 for fastening the flap disc on a machine.
  • the arranged perpendicular or inclined to the axis of rotation are fan-like or roof tile-like each other overlapping slats 10 attached, preferably glued.
  • the fins 10 have radially outer sides 11, which end with the edge of the carrier plate or tower above it and the straight or can be curved.
  • the slats 10 consist of two types of slats, first slats 12, consisting of a base 14, a basic bond layer 15 applied thereon, one applied to the base bond layer 15 Spreading layer made of abrasive grain 16 and one on the abrasive grain scattering layer 16 applied cover layer 18, and second slats 20, consisting of a base 22 and a layer 24 applied to the base with abrasive substances, cf. 2 and 3.
  • the abrasive grain 16 is partially in the Basic bond layer 15 embedded and the cover layer 18 is chosen only so strong that the abrasive grain with its tips protrude from the top layer, cf. Fig. 2.
  • the cover layer 18 of the first slats 12 can additionally provided with abrasive substances his.
  • grinding active substances for example Potassium fluoroborate, cryolite, calcium fluoride and chiolite used.
  • Example 1 In a known manner, grinding lamellae were glued in a fan-like overlapping manner on a carrier disk of 115 mm in diameter. 60 slats with a size of 18 x 25 mm were used.
  • the abrasive flaps consisted of a base made of equipped polyester fabric with a base bond layer, in which zirconium corundum in grain 40 was sprinkled in an amount of 700 g / m 2 as abrasive grain, a first cover bond applied to the abrasive grain scattering layer with an application of 300 g / m 2 , which ensures the strength of the abrasive grain layer, and a second cover bond with an abrasive substance (potassium fluoroborate), which supports the grinding process, and which was applied with a binder in an amount of 380 g / m 2 .
  • an abrasive substance potassium fluoroborate
  • This flap disc was tested on a machine with a speed of 4,200 rpm, which has a cutting speed of 25 m / sec. equivalent.
  • Round pipes made of V2A 4301 with an outside diameter of 90 mm and a wall thickness of 10 mm were ground. 153 g of material were machined in 10 intervals of 5 minutes each.
  • Example 2 Grinding lamellae according to Example 1 were glued to the carrier disk, the following lamellae being used alternately.
  • the 1st, 3rd, 5th etc. consisted of material as in Example 1, but without a second cover binding.
  • the 2nd, 4th, 6th, etc. lamella consisted of a base on which only one layer was applied, which contained potassium fluoroborate as an abrasive substance and was applied with a binder in an amount of 480 g / m 2 . 373 g of material were machined under the same conditions as in Example 1.
  • Example 3 According to Example 2, one was Flap disc made, which grinding flaps according to Example 1, however, without a second cover binding and lamellas from a base with only one active grinding Containing coating in the ratio of 1: 2 d. H. the disc only showed 1/3 of the amount of abrasive grain from Example 1. With this disc were under same conditions as in Example 1 353 g of material machined.
  • Example 4 There was a flap disc prepared according to Example 2, in which the grinding active Substance potassium fluoroborate was replaced by cryolite. This disc was made under the same conditions as in Example 1, 394 g of material are machined.
  • Example 5 There was a flap disc prepared according to Example 1, using instead of zirconium corundum as abrasive grain sintered alumina the same Grain size was used. It was with this disc under the same conditions as in Example 1 201 g Machined material.
  • Example 6 A flap disc according to the example 4 was made with sintered aluminum oxide instead of zirconium aluminum oxide manufactured. It was under with this disc same conditions as in Example 1 370 g material machined.
  • Example 7 A flap disc according to example 6 was made with fins, the calcium carbonate instead of cryolite as an active abrasive contained. With this disc were among the same Conditions as in Example 1, 203 g of material machined.
