Abstract

Zum Entfernen des Brennbartes an Halbzeugmaterial, das durch Brennschneiden geschnitten wurde, dient ein schräggeführter Flachmeißel mit pulsierendem Antrieb mit­ tels eines Preßluftschlaggerätes, wodurch die Vorschub­ kräfte niedrig gehalten werden. Die Neigung des Flachmei­ ßels ist entgegen einer nachhaltigen Kraft im Betrieb verän­ derlich, damit die Meißelschneide Unebenheiten der den Brennbart tragenden Materialoberfläche, z. B. bei gewölb­ ten Brammen, zu folgen vermag und stets zwischen Materi­ aloberfläche und Brennbart angreift. Der relative Vorschub zwischen Flachmeißel und Halbzeugmaterial ist variabel ausgelegt, so daß ein beschleunigter Vorschub einsetzt, wenn ein Stück Brennbart voreilend abplatzt. To remove the mustache from semi-finished material, that was cut by flame cutting serves a inclined flat chisel with pulsating drive with means of a compressed air percussion device, whereby the feed forces are kept low. The inclination of the Flachmei ßels has changed in the company against a sustainable force so that the chisel edge unevenness of the Brennbart bearing material surface, e.g. B. with vault slabs, can follow and always between matter surface and stinging beard. The relative feed between flat chisel and semi-finished material is variable designed so that an accelerated feed starts, when a piece of nettle flakes off prematurely.
