Description
Uberwachung der Abnutzung mittels radioaktiver Messungen Die Erfindung bezieht sich auf eine Anordnung zur t)erwachung der Abnutzung, insbesondere von Werkzeugen, mittels radioaktiver Messungen. Monitoring of wear by means of radioactive measurements The invention refers to an arrangement for t) awakening the wear and tear, in particular of Tools, using radioactive measurements.
Es ist bekannt, Gegenstände verschiedener Art, in fester, flüssiger oder anderer Form, im ganzen oder an der Oberfläche mit radioaktiven Isotopen zu versehen und so entweder ihren Verarbeitungs- oder Bewegungszustand bzw. ihre Lage überwachen zu können. Diese Messungen können sowohl einmalig als auch laufend erfolgen, um etwa selbsttätig entsprechende Vorgänge zu steuern. It is known objects of various types, in solid, liquid or other form, in whole or on the surface with radioactive isotopes too and so either their processing or movement state or their location to be able to monitor. These measurements can be carried out both once and continuously, in order to control corresponding processes automatically.
Die Abnutzung von Autoreifen, Maschinenteilen oder Werkzeugen wurde beispielsweise an den radioaktiven Abfällen oder an Spuren gemessen, die sie an anderen Gegenständen hinterlassen. Der Erfinder hat sich demgegenüber die Aufgabe gestellt, die Brauchharkeit eines Gegenstandes, d. h. seine Abnutzung, während seiner Benutzung feststellen zu können, ohne daß er berührt wird. Diese Aufgabe wird erfindung gemäß gelöst durch eine Anordnung zum Überwachen der Abnutzung, insbesondere von Werkzeugen, mittels radioaktiver Messungen, die dadurch gekennzeichnet ist, daß das Werkzeug an der Oberfläche seiner Schneidenteile radioaktiv gemacht ist, beispielsweise durch eine radioaktive Hartchromschicht, so daß seine Radioaktivität, d. h. deren unzulässige Abnahme, während des Betriebes gemessen und dadurch Signalgebung, Maschinenstilisetzung od. dgl. veranlaßt wird. The wear and tear of car tires, machine parts or tools has been for example, measured in terms of radioactive waste or the traces it shows other objects. The inventor, on the other hand, has the task posed, the usefulness of an object, d. H. its wear, during its To be able to determine use without being touched. This task becomes an invention according to solved by an arrangement for monitoring the wear, in particular of Tools, by means of radioactive measurements, which is characterized in that the tool is made radioactive on the surface of its cutting parts, for example through a radioactive hard chrome layer so that its radioactivity, i.e. H. whose impermissible acceptance, measured during operation and thus signaling, machine shutdown or the like.
Umlaufende, aus mehreren Stählen bestehende und auch von Rühlflüssigkeit bespülte Werkzeuge werden an ihren Schneidenteilen radioaktiv gemacht. Dieses kann beispielsweise mittels eines Hartchromüberzuges, welcher radioaktiv gemacht ist, geschehen. Das so armierte Werkzeug ist durch einen Strahlungsmesser (Geigerzähler), welcher während der Überwachung im unveränderlichen Abstand vom Werkzeug angeordnet und auf dieses eingestellt ist, ständig kontrollierbar. Die anfängliche und normale Strahlungsintensität wird bei unzulässiger Schneidenlabnutzung oder gar Bruch einer der Werkzeugschneiden unmittelbar durch Veränderung, z.B. Verminderung der im eingestellten Meßbereich befindlichen Teile, z. B. durch Abbrechen der Teile, wodurch sie aus dem eingestellten Meßbereich gelangen, merklich verringert. Damit wird auch die am Straklungsmesser eingestellte Minimumgrenze des Ansprechnormalwertes verändert, z. B. unterschritten. Diese Veränderung wird über Relais, Verstärker und Steuer- sowie Anzeigegeräte in an sich bekannter Weise auf den Antrieb wirksam gemacht, indem dieser zur weiteren Schadensverhütung abgeschaltet wird, worauf man den Schaden sofort beheben kann. Circumferential, consisting of several steels and also of coolant Washed tools are made radioactive at their cutting edges. This can for example by means of a hard chrome coating that has been made radioactive, happen. The tool armored in this way is through a radiation meter (Geiger counter), which is arranged at an unchangeable distance from the tool during monitoring and is adjusted to this, constantly controllable. The initial and normal Radiation intensity is increased in the event of impermissible cutting edge wear or even breakage the tool cutting edge directly through change, e.g. reduction of the set Parts located in the measuring area, e.g. B. by breaking off the parts, making them out reach the set measuring range, noticeably reduced. This also becomes the The minimum limit of the normal response value set on the radiation meter has been changed, z. B. fallen below. This change is made via relays, amplifiers and control as well as display devices made effective on the drive in a manner known per se, by turning it off to prevent further damage, whereupon the damage is done can fix it immediately.
Die beschriebene Anordnung hat den Vorteil, durch indirekte Meßmittel- und Geräteanwendung das Prüfgut oder den zu überwachenden Gegenstand hinter Schutzverkleidung usw. kontrollieren zu können. Das ist bei schnellen Bewegungen des zu überwachenden Gegenstandes oder Stoffes von nicht zu unterschätzender Bedeutung. Unfallgefahr, Beschädigungen von Stoff und Apparatur usw. werden dadurch ausgeschaltet. The arrangement described has the advantage of using indirect measuring means and device application the test material or the object to be monitored behind protective cover etc. to be able to control. This is the case with rapid movements of the person to be monitored Object or substance of importance that should not be underestimated. Risk of accident, Damage to material and equipment, etc. is eliminated.
In allen Fällen wird immer nur eine sehr geringe Radioaktivität benutzt, welche weder bei der Verwendung der entsprechenden Stoffe oder ihrer Benutzung nachteilig oder schädlich wirken kann, wohl aber mit den empfindlichen Meßgeräten an sich genau feststellbar ist. In all cases only a very low level of radioactivity is used, which is not disadvantageous either in the use of the corresponding substances or their use or can have a harmful effect, but with the sensitive measuring instruments it is actually accurate is detectable.
