Description
Die Erfindung bezieht sich auf einen Hohl-' flansch aus gepreßtem Blech.

Such hollow flanges are known, but in .; Forms that are unfavorable in a static relationship and in some cases require a cumbersome manufacturing process. There are, for example, essentially Z-shaped bent sheet metal flanges known, but little Stiffness' so that the bent

Das Wesen der Erfindung besteht darin, daß der Holilflansch aus einem äußeren Ring 'mit U-fömiigen Schenkelabbiegungen besteht, in welche ein Innenring mit ebenfalls U-förmigen Sehenkelabbicgungen eingesetzt ist.The essence of the invention is that the Holilflansch consists of an outer ring 'with U-shaped leg bends, in which an inner ring with likewise U-shaped See kelabbicgungen is used.
Bildet man die eine U-förmige Schenkelabbiegung des äußeren Ringes nur als Stumpf aus •und den inneren Ringteil aus zwei spitzwink- : ligen Schenkeln, deren längerer sich in der. Hohlkehle des Schenkelstumpfes des äußeren Ringes abstützt, so erhält man einen Hohl-■flansch von im wesentlichen dreieckigem Querschnitte. Die aufeinanderstoßenden Kanten bzw, Flächen dieser Flansche können verschweißt oder verlötet werden. Diese Flansche besitzen große Steifigkeit gegen Verbiegungen, lassen also ein scharfes Anziehen der Bolzen zu. Die Herstellungsart ist sehr billig, da mau mit einem gewöhnlichen Preßvorgang" und mit einer geringen Zahl von Preßstempeln auskommt. ·.· .■■·.·By forming the spitzwink- a U-shaped leg bend of the outer ring only from • stump and the inner ring part of two: legs time, the longer in the. If the fillet of the leg stump of the outer ring is supported, a hollow flange of essentially triangular cross-section is obtained. The abutting edges or surfaces of these flanges can be welded or soldered. These flanges have great rigidity against bending, so they allow the bolts to be tightened sharply. The method of production is very cheap, since you can get by with an ordinary pressing process and with a small number of press punches. ·. ·. ■■ ·. ·
