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.

Description
Die vorliegende Erfindung betrifft ein System eines schleifaktiven Trennschleifringes gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a system of a sanding Trennschleifringes according to the preamble of
Kunstharzgebundene Trennschleifscheiben ab einem Durchmesser ≥ 400 mm werden auf stationären Trennanlagen in der metallerzeugenden sowie metallverarbeitenden Industrie zum Ablängen von Stahl, Guß, Sonderlegierungen, Inconell, Titan usw. eingesetzt.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.
Als großer Nachteil erweist sich dabei die generell geringe Ausnutzbarkeit der herkömmlichen Trennscheiben. In Abhängigkeit vorhandener Maschinen sowie großer Materialabmessungen können diese homogenen Trennscheiben im Idealfall bis minimal 45 % des Neudurchmessers, im Mittelwert jedoch nur bis auf 60 % des Ausgangsdurchmessers aufgebraucht werden.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.
Diese verbleibenden Restscheiben müssen sodann nach den jeweiligen nationalen Entsorgungsrichtlinien kostspielig entsorgt werden. Als weiterer Nachteil ist der zusätzliche Rohstoffeinsatz für diese ungebrauchte Kernzone anzuführen, welcher trotz alternativer Schleifkornmaterialien hinsichtlich Armierung und Harzanteil zusätzliche Kosten am Rohstoffsektor ergibt.These remaining washers then have to be disposed of costly according to the respective national disposal guidelines. Another disadvantage is the additional use of raw materials for this unused core zone, which results in additional costs in the raw materials sector despite alternative abrasive grain materials in terms of reinforcement and resin content.

Aufgabe der vorliegenden Erfindung ist es daher, ein Verbundsystem zu schaffen, das vorgenannte Nachteile ausschließt und dem Anwender ein Aufbrauchen des äußeren Trennschleifringes von bis zu 95 % der gesamten schleifaktiven Trennringfläche ermöglicht und zusätzliche Vorteile wie reduzierte Trennscheibenbreite bei sogar höherer Stabilität gewährleistet.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.
Dies wird erfindungsgemäß nach Anspruch 1 dadurch erreicht, dass der Bohrungsdurchmesser des Trennschleifringes auf den minimalen Aufbrauchdurchmesser abgestimmt wird und zusätzlich hier beidseitig versetzte Vertiefungen für die Randform der beiden Spanntafeln eingepresst sind. Dadurch ist ein fast vollständiges Aufbrauchen der schleifaktiven Randzone möglich und es muss nur mehr ein kleiner abrasiver Restring entsorgt werden.This is inventively achieved according to
Ein wesentlicher Bestandteil der Erfindung sind die beiden Spanntafeln, welche als Verbindungselemente zwischen den eigentlichen maschinenseitigen Spannflanschen und dem schleifaktiven Trennring zu verstehen sind. Da speziell der Übergang vom Spannflansch zur Trennscheibe bei herkömmlichen Produkten eine Schwachstelle darstellt, wird hier erfindungsgemäß dieser Nachteil durch den alternativ möglichen Werkstoff der Spanntafeln wesentlich verbessert.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.
Da die beiden Spanntafeln beim Anwender verbleiben, muss nur noch der wesentlich leichtere Trennring zum Kunden versandt werden; dabei ist eine Gewichtseinsparung von bis zu 40 % möglich.Since the two clamping panels remain with the user, only the much lighter separating ring has to be sent to the customer; a weight saving of up to 40% is possible.

Bei den in den Figuren dargestellten Trennschleifring 1 handelt es sich um eine kunstharzgebundene Trennschleifscheibe ohne, vorzugsweise aber mit zusätzlicher Gewebeverstärkung 5. Durch eine gezielte Auswahl von Phenolharzen in Kombination mit abgestimmten Schleifkörnungen und Füllstoffen werden die verschiedenen Härtegrade den jeweiligen Anwendungserfordernissen und Kundenwünschen angepasst.The abrasive cut-off
Als Schleifmittel werden bevorzugt Korunde, im Speziellen jedoch Spezial-, Zirkon- und Sinterkorunde sowie auch Siliciumkarbid verwendet. Die Füllstoffe setzen sich aus Rohstoffen wie Pyrit, Zinksulfid, Grafit, Kaliumchlormanganat usw. zusammen, welche auch derzeit in Trennscheiben für Industrieanwendungen eingesetzt werden.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.
Als Gewebeverstärkung 5 kommen derzeit Glasgewebeeinlagen zur Anwendung, in Zukunft sind hier jedoch auch Alternativen wie Kevlar oder Kohlefaser denkbar. Eine Ausführung ohne durchgehende Armierung ist möglich, im Bereich von Vertiefungen 3 sollten jedoch Verstärkungen vorgesehen werden.Glass fabric inserts are currently used as
Der Außendurchmesser D des Trennschleifringes 1 liegt üblicherweise zwischen 400 mm und 2000 mm, bevorzugt jedoch größer 800 mm. Der Bohrungsdurchmesser d vom Trennschleifring 1 kann idealerweise auf den anwendungsbezogenen Minimaldurchmesser abgestimmt werden. Aus fertigungstechnischen Gründen sollte jedoch eine Fixbohrung, bezogen auf die jeweilige Standardabmessung des Trennringes, gewählt werden. Als Richtwert für den Bohrungsdurchmesser d ist der Bereich 40 bis 80 % vom Außendurchmesser D anzugeben.The outer diameter D of the
Die Verhältniszahl vom Durchmesser D zur Breite T liegt derzeit üblicherweise im Bereich 80 bis 100. Eine erfindungsgemäße Steigerung auf bis zu 130 ist auf Grund der wesentlich steiferen Kernzone realisierbar. Der schleifaktive Trennring kann sowohl planparallel als auch konisch, das heißt zur Bohrung verjüngt, ausgeführt sein.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.
Aus Gründen der Übersichtlichkeit ist die Breite T in den
Der Trennschleifring 1 weist planseitig im Bohrungsbereich beidseitig mehrere geometrische Vertiefungen 3 auf, in welche beim Aufspannen die beiden Spanntafeln 2 passgenau eingelegt werden. Die Form dieser Vertiefungen 3 kann rund, rechteckig, vorzugsweise jedoch schwalbenschwanzförmig ausgeführt sein. Um eine gute Vorspannung der Spanntafeln 2 zu ermöglichen, muss die Tiefe dieser Ausnehmungen zwischen 0,1 mm und 1 mm vorzugsweise 0,2 mm bis 0,6 mm geringer sein, als die halbe Trennringbreite T in der Bohrung. Die radiale Erstreckung e dieser Ausnehmungen 3 ist abhängig vom Außendurchmesser D und liegt zwischen 10 mm und 200 mm, vorzugsweise zwischen 30 mm und 60 mm.The separating
Ein wesentlicher Bestandteil dieses Systems sind die beiden Spanntafeln 2, welche mit ihrer definierten Randform genau in die beidseitigen Vertiefungen 3 des Trennschleifringes 1 passen. Beim Aufspannen mit den herkömmlichen Spannflaschen 4a und 4b werden die beiden Spannbleche zusammengepresst und es wird dadurch die notwendige seitliche Spannkraft erzeugt. Die für einen Zerspannungsprozess notwendigen Kräfte werden dabei von der Antriebswelle über die Spannflansche 4a, 4b auf die beiden Spanntafeln 2 weitergeleitet und von diesen letztendlich über die spezielle Randform auf den schleifaktiven abrasiven Trennring kraftschlüssig übertragen.An essential component of this system are the two
Die Spanntafeln 2 können in gerader, gekröpfter, perforierter bzw. auch in gewellter Form ausgeführt sein. Als Möglichkeit der Gewichtseinsparung können die Spanntafeln 2 mit zusätzlichen Ausnehmungen versehen werden.The
Die Randform dieser beiden Spanntafeln 2 zeichnet sich durch mehrere symmetrische runde, eckige, schwalbenschwanzförmige oder ähnlich geformte vorstehenden Spannflächen aus, welche genau in die beidseitig mitgepressten Vertiefungen 3 des schleifaktiven Trennringes passen müssen und so die auftretenden Kräfte während des Trennschleifens übertragen können.The edge shape of these two
Die Gesamtstärke der beiden Spanntafeln 2 muss geringfügig, das heißt ungefähr 5 bis 10 % dünner sein als die Scheibenstärke im Bohrungsbereich des Trennschleifringes 1. Dadurch ist es gewährleistet, dass die notwendige freie Schnitttiefe wie mit herkömmlichen Trennscheiben erreicht wird.The total thickness of the two
Als Werkstoff für diese Spanntafeln 2 kommen hochfeste armierte Kunststoffe, Kohlenstoffaser, Nichteisenmetalle, Sonderlegierungen, Titan, vorzugsweise jedoch derzeit einfache Stahlbleche zur Anwendung. Zusätzlich zur erforderlichen Grundfestigkeit, muss dieser Werkstoff als wichtiges Kriterium eine gewisse Flexibilität und hohe Eigenspannung aufweisen, um die bei solchen Anwendungen auftretenden seitlichen Krafteinwirkungen ohne dauernden Schaden überstehen zu können.As a material for these
Um das Handling beim Aufspannen dieses Verbundsystems zu erleichtern, werden in den Spanntafeln Schlitze 2a vorgesehen, in welche spezielle Spannfedern als Aufspannhilfe eingeschoben werden. Als zusätzliche Fixierung bzw. Spannkrafterhöhung können bei sehr großen Spanntafeln (> 60 % vom Trennring-Außendurchmesser) zusätzliche Verschraubungen 2b im äußeren Durchmesserbereich der Spanntafeln 2 vorgesehen werden. Dabei dürfen keine Verschraubungselemente über die Planflächen der Spanntafeln 2 vorstehen.In order to facilitate handling when mounting this composite system,
Als wichtige Fertigungsmaßnahme ist ein positions- und formgenaues Einpressen der Vertiefungen 3 im Bohrungsbereich des Trennschleifringes 1 notwendig. Dies wird durch das Mitpressen einer passgenauen Schablone erreicht. Alternativ können diese Ausnehmungen auch nachträglich auf einer geeigneten Bearbeitungsanlage ausgeschliffen werden.As an important production measure, a position and shape-accurate press-fitting of the
