Description

Verfahren zur Herstellung ringförmiger, geschmiedeter Verbundkörper Es wurde bereits vorgeschlagen, Verbundkörper ' aus verschiedenartigen Stählen zu schmieden oder zu walzen. Ferner ist bekannt, von Verbundgußkörpern Scheiben abzutrennen und dieselben z. B. durch Schmieden weiterzuverarbeiten.Process for the production of annular, forged composite bodies It has already been proposed to 'composite bodies' made of various types of steel forging or rolling. It is also known to separate disks from composite castings and the same z. B. further processed by forging.

Befriedigende Ergebnisse konnten aber mit diesen Verfahren nicht erreicht werden, da ein nur von außen wirkender Walz- oder Schmiededruck wegen der verschieden starken Verformung ein Aufreißen vorwiegend in der Übergangszone der beiden den Verbundkörper bildenden Stähle verursachte.However, satisfactory results could not be achieved with these methods because a rolling or forging pressure acting only from the outside because of the different severe deformation, a tear mainly in the transition zone between the two den Composite steels.

Um ringförmige Verbundkörper einwandfrei herzustellen, werden die vom Verbundgußkörper abgetrennten Scheiben oder Ringe erfindungsgemäß über einen Dorn geschmiedet. Durch diese Maßnahme erhalten die Körper von innen Halt, und ein Aufreißen wird wegen der nun mit genügender Gleichmäßigkeit erfolgenden Verformung beider Werkstoffe mit Sicherheit vermieden.In order to produce ring-shaped composite bodies properly, the disks or rings separated from the composite cast body according to the invention via a Forged mandrel. This measure gives the body support from the inside The deformation which now takes place with sufficient uniformity will tear open of both materials definitely avoided.

Aus solchen geschmiedeten Verbundkörpern können mit Vorteil z. B. Fräser, Zahnräder und Ziehringe hergestellt werden. Bei Fräsern und Zahnrädern werden Rohlinge verwendet, bei denen der legierte, harte und verschleißfeste Stahl außen liegt, während für den inneren Teil unlegierter Stahl verwendet werden kann. Bei Ziehringen ist der legierte Stahl innen und der unlegierte außen angeordnet.For such forged composite bodies, for. B. Milling cutters, gears and drawing rings are produced. When milling cutters and gears are Blanks used in which the alloyed, hard and wear-resistant steel outside while mild steel can be used for the inner part. at Draw ring is that alloy steel inside and the unalloyed outside arranged.

Durch den Verbundstahl wird eine große Einsparung an legiertem Stahl erreicht und die Bearbeitung erleichtert.The composite steel results in a large saving in alloy steel achieved and processing easier.

Die Verbundgußkörper können in an sich bekannter Weise durch Gießen in Kokillen oder besonders vorteilhaft durch Schleuderguß hergestellt werden.The cast composite bodies can be cast in a manner known per se can be produced in permanent molds or, particularly advantageously, by centrifugal casting.
