Abstract

Bandsaw blade with improved properties with regard to fatigue strength under reversed bending stresses and to maintaining the internal stress and flatness values by plastic deformation or increased yield point.

Description

Es sind Sägeblätter bekannt, die dazu neigen, daß sie aufgrund der Biegewechselbelastung leicht einreißen und daß sie während des Laufens ihre Innenspannung und Planheit verändern.Saw blades are known which tend to due to the alternating bending load tear down and that while they run their Change internal tension and flatness.

Der Erfindung liegt die Aufgabe zugrunde, ein Sägeblatt zu schaffen, das weniger empfindlich gegen Biegewechsel­ belastungen ist und das seine Innenspannung und Plan­ heitswerte besser beibehält.The invention has for its object a saw blade to create the less sensitive to bending changes is stress and that is his inner tension and plan maintains better values.

Das erfindungsgemäße Sägeblatt ist kurzzeitig bei der Herstellung über die Fließgrenze hinaus nach dem Härten durch sehr hohe Zugspannungen plastisch verformt; Langsägen in Längsrichtung des Bandes durch von außen aufgebrachte Zugkräfte und Kreissägen durch radial wirkende Zugkräfte oder durch sehr hohe Flieh­ kraftspannungen.The saw blade according to the invention is briefly at manufacturing beyond the yield point hardening through very high tensile stresses deformed; Long saws in the longitudinal direction of the band externally applied tensile forces and circular saws radial tensile forces or very high centrifugation power tensions.

Claims (2)

1. Sägeblatt, dadurch gekennzeichnet, daß im gehärteten Zustand durch plastische Verformung die Streckgrenze des Sägenkörperstahls erhöht ist.1. Saw blade, characterized in that the yield strength of the saw body steel is increased by plastic deformation in the hardened state. 2. Sägeblatt nach Anspruch 1, dadurch gekennzeichnet, daß die plastische Verformung über die Sägendicke unterschiedlich ist und vorzugsweise in den Rand­ zonen größer als in der Dickenmitte.2. Saw blade according to claim 1, characterized in that the plastic deformation over the saw thickness is different and preferably in the edge zones larger than in the middle of the thickness.
