Abstract

Unterbewicklungen (Befederungen) von Mangelwalzen (10) werden aus einer Vielzahl von Lamellenfedern (15) gebildet. Teilweise brechen diese Lamellenfedern (15) nach verhältnismäßig kurzer Betriebszeit der Mangel. Das führt dazu, daß die Unterbewicklung vorzeitig erneuert oder repariert werden muß.Under-winding (feathering) of ironing rollers (10) formed from a plurality of lamella springs (15). Partially break these lamellar springs (15) after a relatively short time Operating time of the shortage. As a result, the Underwrapping must be renewed or repaired prematurely.

Erfindungsgemäß ist vorgesehen, die Lamellenfedern (15) mit einer bestimmten Stanzrichtung aus einem Zuschnitt aus Federstahl auszustanzen. Diese Stanzrichtung ist so gewählt, daß ein dabei auf einer Seite des Zuschnitts entstehender Stanzgrat auf der beim Betrieb der Mangel druckbelasteten Seite der Lamellenfedern (15) liegt. Es hat sich gezeigt, daß der Stanzgrat auf der druckbelasteten Seite der Lamellenfedern (15) die Bruchgefahr der Federfinger (18) reduziert und dadurch die Lebensdauer der Lamellenfedern (15) und damit der Unterbewicklung erhöht.

Figure 00000001
According to the invention, the lamella springs (15) are punched out with a specific punching direction from a blank made of spring steel. This punching direction is selected so that a punch burr that arises on one side of the blank lies on the side of the lamella springs (15) that is under pressure during operation of the mangle. It has been shown that the punching ridge on the pressure-loaded side of the plate springs (15) reduces the risk of breakage of the spring fingers (18) and thereby increases the service life of the plate springs (15) and thus the under-winding.
