Procedure for hardening slides of a perforating press and the slides obtained

Abstract

The present invention relates to a method of hardening slides of a perforating press comprising providing a steel beam; hardening of the steel beam in a vacuum furnace; tempering the steel beam twice; first straightening of the steel beam at a temperature of 20° C.±10° C.; milling of an at least partially continuous sawtooth profile, along a longitudinal direction of the steel beam, on a first side of the steel beam; wherein, after milling the at least partially continuous sawtooth profile on the first side of the steel beam, a second side of the steel beam, lying opposite the first side, is hardened by means of induction currents, after which the steel beam is again tempered twice and after which the steel beam is straightened a second time at a temperature of 20° C.±10° C. The invention also relates to a slide for a perforating press hardened according to the method.
