Abstract

Kernverbindungsstange mit fest montierter Tellerfeder oder Tellerfederpaket, dadurch gekennzeichnet, dass eine Tellerfeder oder mehrfach geschichtete Tellerfedern (2) (Werkstoff Federstahl) auf der Scheibe (3) (Werkstoff DC01) und der Stange (1) (Werkstoff RSt36) fest verbunden sind. Das Element ist in sich mit allen Teilen (Stange (1) Tellerfeder (2) und der Scheibe (3)) zusammengenietet oder -geschweißt.Core connecting rod with fixed plate spring or disc spring package, characterized in that a plate spring or multi-layered disc springs (2) (spring steel material) on the disc (3) (DC01 material) and the rod (1) (RSt36 material) are firmly connected. The element is riveted or welded together with all parts (rod (1) disc spring (2) and disc (3)).

Description

Gießformen bestehen in der Regel aus mehreren Form- und Kernteilen. Diese aus Formsand und Bindemittel vorgefertigten Teile werden durch Kleber, Sonderschrauben und/oder Gewindestangen, sog. Kernverbindungsstangen, zusammengefügt. Anschließend werden die Gießformen in ein Schlichtbad getaucht und in einem Ofen getrocknet. Durch die unterschiedlichen Ausdehnunsgkoeffizienten der Materialien löst sich die starre Gewindestange nach dem Trocknen und muss nach der Abkühlung nachgezogen werden.molds usually consist of several mold and core parts. This off Molding sand and binder prefabricated parts are made by adhesive, special screws and / or threaded rods, so-called. Kernverbindungsstangen, put together. Then be the molds dipped in a sizing bath and dried in an oven. By the different Ausdehnunsgkoeffizienten the materials dissolves The rigid threaded rod after drying and must be tightened after cooling become.

Neu und erfindungsgemäß an dieser Kernverbindungsstange ist, dass sich unter der Platte (3) eine fest montierte oder mehrfach geschichtete Tellerfederneinheit, abgestimmt auf das Anzugsdrehmoment der Gewindestange (1), befindet, durch die die Längenausdehnung kompensiert wird. Hauptvorteil dieser Erfindung ist eine Zeitersparnis, da das Nachziehen des Verbindungselementes entfällt und das Kernpaket während des gesamten Abkühlvorganges transportfähig bleibt.New and according to this core connecting rod is that under the plate ( 3 ) a fixed or multi-layered disc spring unit, matched to the tightening torque of the threaded rod ( 1 ), by which the length expansion is compensated. The main advantage of this invention is a time saving, since the tightening of the connecting element is eliminated and the core package remains transportable during the entire cooling process.
