Abstract

The invention relates to an electric power supply for the furnace of a high-temperature isostatic pressing installation having electrical resistance heating, the design of the electrical power supply being provided as a round-plug connection, having a plug (2) which is mounted on the base plate (3) of the furnace, and having a contact socket (1) with a threaded connection (8), which is screwed directly into the electrical bushing of the lower closure cover (4). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Stromzuführung für den Ofen einer HIP-Anlage mit elektrischer Widerstandheizung.The invention relates to a power supply for the furnace HIP system with electrical resistance heating.

Öfen in HIP-Anlagen (Heiß-Isostatischen-Pressen) haben elektrische Widerstandsheizungen, und deshalb muß die elektrische Leistung durch einen Verschluß des Druckbehälters der Beschicköffnung gegenüberliegend zum Ofen geführt werden.Furnaces in HIP systems (hot isostatic presses) have electrical ones Resistance heaters, and therefore the electrical power must go through a closure of the pressure vessel opposite the loading opening be led to the oven.

Die elektrische Stromzuführung zum Ofen muß aber auch trennbar sein, da der Ofen nach jedem Preßzyklus aus dem Druckbehälter entnommen werden muß, damit die Entnahme des fertigen Preßlings und die Einfügung des neuen Werkstücks durchgeführt werden kann.The electrical power supply to the furnace must also be separable, because the furnace can be removed from the pressure vessel after each pressing cycle must, so that the removal of the finished compact and the insertion of the new workpiece can be carried out.

Bisher wurden die elektrischen Verbindungen nach der Durchführung mit flexiblen Kupferbändern an die Kontakte der jeweiligen Zonen des Ofens geführt. Die Kontaktflächern wurden durch federvorgespannte Bolzen aufeinandergedrückt. Dies erforderte einen großen räumlichen und mechanisch fertigungstechnischen Aufwand. Durch diese federbelastete Kontaktberührung können, insbesondere bei hohen übertragbaren Leistungen, Kontaktfehler bis hin zum absoluten Störfall auftreten, d. h., daß die Anlage abgeschaltet werden muß.So far, the electrical connections have been carried out after flexible copper strips to the contacts of the respective zones of the furnace guided. The contact surfaces were spring-loaded bolts pressed together. This required a large spatial and mechanical production engineering effort. Through this spring-loaded Can make contact, especially at high transferable Services, contact errors up to absolute malfunctions occur, d. that is, the system must be shut down.

Der Erfindung liegt die Aufgabe zugrunde, eine Stromzuführung zu schaffen, die einen elektrisch sichereren Kontakt ergibt und gut trennbar, sowie mechanisch einfach aufgebaut ist.The invention has for its object to a power supply create that gives an electrically safer contact and good separable and mechanically simple.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst.This task is carried out in the characterizing part of the Features specified claim 1 solved.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die gefundene Lösung kontaktsicher, einfach aufgebaut und beim Preß-Zykluswechsel einfach und ohne technische Probleme trennbar und wieder verbindbar ist. Durch die Stromzuführung gemäß der Erfindung wird auch wesentlich weniger Platz benötigt, und der fertigungstechnische Aufwand ist geringer.The advantages achieved with the invention are in particular that the solution found is reliable, simple to set up and Press cycle changes can be separated easily and without technical problems is connectable again. By the power supply according to the invention also requires significantly less space, and the manufacturing technology Effort is less.

Die HIP-Anlage wird mit der Stromzuführung nach der Erfindung betriebssicherer.The HIP system comes with the power supply according to the invention reliable.

Die Zeichnung zeigt in einem Ausschnitt und in einem einzigen Ausführungsbeispiel die Stromzuführung ab den unteren Verschlußdeckel 4 des Druckbehälters (nicht dargestellt) bis zu den auf der Basisplatte 3 des Ofens gestapelten Isolationsschichten 5. Die Stromzuführung selbst besteht aus der Kontaktbuchse 1 mit Gewindeanschluß 8 und den Stecker 2. Der Stecker 2 ist an der Basisplatte 3 des Ofens der jeweiligen Heizzone befestigt. Die Kontaktbuchse 1 mit Gewindeanschluß 8 ist direkt in die Stromdurchführung im unteren Verschlußdeckel 4 in ein Gewindeteil eingeschraubt. Beim Einsetzen des Ofens in den Druckbehälter wird somit die Stromverbindung durch die Rundsteckverbindungen hergestellt. Mit 6 ist eine Isolationsplatte bezeichnet, die zwischen der Basisplatte 3 des Ofens und dem unteren Verschlußdeckel 4 für eine Wärmedämmung nach außen sorgen soll.The drawing shows in a detail and in a single embodiment the power supply from the lower closure cover 4 of the pressure vessel (not shown) to the insulation layers 5 stacked on the base plate 3 of the furnace. The power supply itself consists of the contact socket 1 with threaded connection 8 and the plug 2 . The plug 2 is attached to the base plate 3 of the furnace of the respective heating zone. The contact socket 1 with a threaded connection 8 is screwed directly into the current feedthrough in the lower sealing cover 4 into a threaded part. When the furnace is inserted into the pressure vessel, the electrical connection is thus established through the circular plug connections. 6 with an insulation plate is designated, which is to provide thermal insulation to the outside between the base plate 3 of the furnace and the lower cover 4 .
