Abstract

Casting insert for insertion in a mould to produce wear-protected castings, consists of two or more perforated steel sheets with sintered carbide balls of a larger dia. than the perforations placed in the perforations between the sheets in single or multiple layer. Pref. the carbide balls between the sheets are retained in place by fastening the sheets together. The balls may be freely positioned as required. USE/ADVANTAGE - Used in the foundry industry to produce armoured, wear-protected ferrous castings. Sub-standard or reject perforated sheet and carbide balls may be used.

Description

Die Erfindung betrifft die Herstellung von verschleißge­ schützten Gußstücken auf der Basis von Eisenwerkstoffen. Die Erfindung ist in der Gießereiindustrie anwendbar.The invention relates to the production of wear protect castings based on ferrous materials. The invention is applicable in the foundry industry.

Es ist bekannt, bei der Herstellung von verschleißge­ schützten Gußstücken zum Zwecke der Panzerung Verschleiß­ stoffe mittels Kern, Armierungen, Formteilen oder Eingieß­ elementen (P 41 14 725.1) in die Gießform einzubringen. Nachteilig ist bei diesen Verfahren, daß hierbei teure, hitzebeständige Binder verwendet werden. Die exakte An­ ordnung von Eingießelementen muß gemäß der Geometrie des jeweiligen Gußteils erfolgen, um das Einschweißen des Hart­ metalls bzw. die rückstandslose Vergasung des Binders zu ge­ währleisten.It is known in the manufacture of wear protect castings for the purpose of armor wear fabrics by means of core, reinforcement, molded parts or pouring elements (P 41 14 725.1) into the mold. A disadvantage of these processes is that they involve expensive heat-resistant binders can be used. The exact type Order of pouring elements must be in accordance with the geometry of the each casting is done to weld the hard metal or the residue-free gasification of the binder ensure.

Der Erfindung liegt die Aufgabe zugrunde, Gußteile herzu­ stellen, die nicht nur an der Oberfläche, sondern auch im Inneren des Gußkörpers verschleißgeschützte Zonen aufweisen.The object of the invention is to produce castings places that are not only on the surface, but also in the Have wear-protected zones inside the cast body.

Erfindungsgemäß wird die Aufgabe durch den Einsatz von spe­ ziellen Eingießkörpern gelöst.According to the invention, the object is achieved by using spe main pouring bodies solved.

Ein Eingießkörper besteht aus mehreren aber mindestens zwei übereinander angeordneten perforierten Blechen, wobei zwischen den Blechen in deren Perforierung Hartmetallkugeln ein- oder mehrlagig eingesetzt sind, deren Durchmesser größer ist als die Perforierung. A casting body consists of several but at least two perforated sheets arranged one above the other, with between the metal sheets in their perforation are used in multiple layers, the diameter of which is greater than the perforation.  

Die Hartmetallkugeln werden durch Verklammerung der Bleche in ihrer Position gehalten.The hard metal balls are clamped together by the sheets held in place.

Der Abstand zwischen den Hartmetallkugeln und die Verteilung zwischen den einzelnen Blechen kann, entsprechend dem Ver­ wendungszweck, frei gewählt werden.The distance between the carbide balls and the distribution between the individual sheets, according to Ver purpose, can be chosen freely.

Nachfolgend ist die Erfindung anhand eines Ausführungsbei­ spieles näher erläutert. In der dazugehörigen Zeichnung wird der einschichtige Ein­ gießkörper dargestellt, der in eine Verschleißplatte (6) eingegossen werden soll.The invention is explained in more detail using an exemplary embodiment. In the accompanying drawing, the single-layer cast body is shown, which is to be poured into a wear plate ( 6 ).

Für den einschichtigen Eingießkörper, gemäß Fig. 1 und 2, werden zwei entsprechend perforierte (hier Bohrungen) Bleche (1) benötigt in deren Perforierung (2) Hartmetallkugeln (3) dazwischen gelagert und durch Verklammern, hier mit Gewinde­ stiften (4), gegen Verschiebungen gesichert. Mit zusätzlichen Öffnungen (5) wird eine bessere Durchflutung und damit eine sichere Verschmelzung zwischen Gießmetall und Eingießkörper gewährleistet. Die überstehenden Gewindestifte haben nicht nur die Aufgabe den Eingießkörper zusammenzuhalten, sondern gewährleisten auch die richtige Lage im Gußteil. Während des Gießprozesses strömt das Gießmetall durch den Eingießkörper und umhüllt die Hartmetallkugeln (3) einschließlich Gewinde­ stiften (4) sowie Bleche (1). Das Gießmetall erstarrt mit dem eingeschweißten Eingießkörper zu einem qualitativ hochwertigen und verschleißfesten Gußteil (6).For the single-Eingießkörper, according to FIG. 1 and 2, two correspondingly perforated (here holes) sheets (1) required in the perforation (2) of hard metal balls (3) interposed therebetween and by clamping, cause here with thread (4), against Movements secured. With additional openings ( 5 ) a better flooding and thus a safe fusion between the casting metal and the pouring body is guaranteed. The protruding set screws not only have the task of holding the casting body together, but also ensure the correct position in the casting. During the casting process, the casting metal flows through the casting body and envelops the hard metal balls ( 3 ) including threaded pins ( 4 ) and sheets ( 1 ). The cast metal solidifies with the welded-in casting body to form a high-quality and wear-resistant cast part ( 6 ).

Vorteile der ErfindungAdvantages of the invention

Die Vorteile der Erfindung bestehen darin, daß für die per­ forierten Bleche kostengünstige Abfallmaterialien, wie Staub­ abfälle und qualitätsgeminderte Hartmetallkugeln mit Maßab­ weichungen Analysen- und Oberflächenfehlern verwendet werden können.The advantages of the invention are that for the per Formed sheets of inexpensive waste materials such as dust waste and quality-reduced carbide balls with dimension analysis and surface defects can be used can.
