Definitions

  • the present invention relates to a system of a sanding Trennschleifringes according to the preamble of claim 1.
  • Resin-bonded cut-off wheels with a diameter ⁇ 400 mm are used on stationary separation plants in the metal-producing and metalworking industry for cutting steel, cast iron, special alloys, Inconell, titanium, etc.
  • a major disadvantage is the generally low exploitation of conventional cutting discs. Depending on existing machines and large material dimensions, these homogeneous cutting discs can ideally be used up to a minimum of 45% of the new diameter, but on average only up to 60% of the original diameter.
  • a Trennschleifring is disclosed which is formed to a central bore out with a full-scale taper.
  • the rejuvenation steel plates are glued in place for reinforcement, so that the glued steel plates cover the tapered area.
  • the object of the present invention is therefore to provide a composite system which excludes the aforementioned disadvantages and allows the user to use up the outer Trennschleifringes of up to 95% of the entire abrasive separating ring surface and ensures additional benefits such as reduced blade width with even higher stability.
  • An essential part of the invention are the two clamping plates, which are to be understood as connecting elements between the actual machine-side clamping flanges and the abrasive separating ring. Since especially the transition from the clamping flange to the cutting disc in conventional products is a weak point, this disadvantage is significantly improved according to the invention by the alternatively possible material of the clamping panels here.
  • the abrasive cut-off ring 1 shown in the figures is a resin-bonded cut-off wheel without, but preferably with additional fabric reinforcement 5.
  • additional fabric reinforcement 5 Through a targeted selection of phenolic resins in combination with coordinated abrasive grains and fillers, the different degrees of hardness are adapted to the particular application requirements and customer requirements.
  • the abrasives used are preferably corundum, but in particular special, zirconium and sintered corundum as well as silicon carbide.
  • the fillers are composed of raw materials such as pyrite, zinc sulfide, graphite, potassium chlorananganate, etc., which are currently used in cutting discs for industrial applications.
  • the outer diameter D of the Trennschleifringes 1 is usually between 400 mm and 2000 mm, but preferably greater than 800 mm.
  • the bore diameter d of the separating slip ring 1 can ideally be adjusted to the application-specific minimum diameter. For manufacturing reasons, however, a fixed bore, based on the respective standard size of the separating ring should be selected. As a guideline for the bore diameter d, the range 40 to 80% of the outer diameter D is given.
  • the ratio of the diameter D to the width T is currently usually in the range 80 to 100.
  • An increase according to the invention to up to 130 is feasible due to the much stiffer core zone.
  • the abrasive separating ring can be both plane-parallel and conical, that is tapered to the bore executed.
  • the separating slip ring 1 has on the plan side in the bore area on both sides of several geometric depressions 3, in which the two clamping plates 2 are inserted accurately when clamping.
  • the shape of these recesses 3 may be round, rectangular, but preferably dovetailed.
  • the depth of these recesses must be between 0.1 mm and 1 mm, preferably 0.2 mm to 0.6 mm less than half the separating ring width T in the bore.
  • the radial extent e of these recesses 3 is dependent on the outer diameter D and is between 10 mm and 200 mm, preferably between 30 mm and 60 mm.
  • An essential component of this system are the two clamping plates 2, which fit with their defined edge shape exactly in the two-sided depressions 3 of the Trennschleifringes 1.
  • the two clamping plates When clamping with the conventional clamping bottles 4a and 4b, the two clamping plates are pressed together and it is thereby produced the necessary lateral clamping force.
  • the necessary forces for a Zerliqueslui be forwarded from the drive shaft via the clamping flanges 4a, 4b on the two clamping plates 2 and transmitted from these ultimately non-positively on the abrasive abrasive ring separating ring on the special edge shape.
  • the clamping panels 2 can be designed in straight, cranked, perforated or in corrugated form. As a way of saving weight, the clamping panels 2 can be provided with additional recesses.
  • edge shape of these two clamping plates 2 is characterized by a plurality of symmetrical round, angular, dovetailed or similarly shaped protruding clamping surfaces, which must fit exactly in the co-impressed depressions 3 of the abrasive separating ring and so can transmit the forces occurring during the cut-off.
  • the total thickness of the two clamping plates 2 must be slightly, that is about 5 to 10% thinner than the thickness of the disc in the bore region of the separating slip ring. 1 This ensures that the necessary free cutting depth is achieved as with conventional cutting discs.
  • these clamping panels 2 are high-strength reinforced plastics, carbon fiber, non-ferrous metals, special alloys, titanium, but preferably currently simple steel sheets for use. In addition to the required basic strength, this material must have a certain degree of flexibility and high residual stress as an important criterion in order to be able to withstand the lateral force effects occurring in such applications without permanent damage.
  • slits 2a are provided in the clamping panels, in which special tension springs are inserted as Aufspann Vietnamese.
  • additional screw connections 2b in the outer diameter region of the tension plates 2 can be provided for very large tension plates (> 60% of the separating ring outer diameter). In this case, no screwing over the flat surfaces of the clamping panels 2 may protrude.
  • a position and shape-accurate press-fitting of the recesses 3 in the bore region of the separating slip ring 1 is necessary. This is achieved by compressing a precisely fitting template. Alternatively, these recesses can also be subsequently ground on a suitable processing plant.
