Abstract:
Ein Schweißaggregat zum Verschweißen von Schienen (19) eines Gleises weist einer zur Entfernung eines Schweißwulstes vorgesehene Abschervorrichtung (13) auf. Diese ist aus einem eine Abscherkante (14) aufweisenden Kopfteil (15) und zwei jeweils eine Abscherkante (16) aufweisenden, zueinander verschwenkbaren Seitenteilen (17) zusammengesetzt. Jedem Seitenteil (17) ist ein zur Anlage an einen Schienenfuß (18) vorgesehener Schienenfußabschnitt (20) zugeordnet, welche in einem einander zugewandten Endbereich eine Verzahnung (27) für eine - nach Anlage der beiden Seitenteile (17) an die Schiene (19) in einer Schienenlängsrichtung wirksame - Formschlußverbindung aufweisen.
Abstract:
A material cutting machine has a tool mount support mounted for reciprocal movement and a tool mount supported by the tool mount support. A driver, such as a pneumatic cylinder, selectively advances and retracts the tool mount support. A control system is operatively coupled to the driver for setting the advancement force of the tool mount support when a tool supported by said tool mount contacts a workpiece, such as the edge or surface of a moving strip. In this way, the depth of cut of the tool is controlled by tool advancement force rather than by accurate positioning of the tool. In one embodiment, the tool mount support may have a head and a base and a resilient member resiliently coupling the head to the base to provide a damped resilience. With this embodiment, a transient spike in the reaction force which may result, for example, from a hard spot in the material, causes the tool to momentarily deflect. Swing links may maintain the lateral positioning of the tool whenever it momentarily retreats due to a reaction force spike. A guide for the tool mount may be pivotably mounted to a frame so that a rake angle of a tool supported by the tool mount may be varied.
Abstract:
The main object of the invention is to provide a cutting method for efficiently cutting long-sized hardened steel material to produce guide rails or the like for rolling guide devices; and a cutting device. To this end, the above problem is solved by a cutting method that linearly cuts a surface (3) extending along the longitudinal direction of a long-sized hardened steel material (2) by a CBN tool (7) at a speed of about 30 m/min to about 160 m/min. At this time, it is desirable that a plurality of CBN tools (7) be provided to simultaneously cut a plurality of surfaces (3), and it is desirable that a plurality of CBN tools (7) be arranged longitudinally of the long-sized hardened steel material (2) to successively cut the surfaces (3). Further, the cutting device of the invention comprises a fixing device (4) for fixing a long-sized hardened steel material (2), a tool post (5) guided by a guide device (6) installed along the longitudinal direction of the fixing device (4), and a CBN tool (7) for cutting the surface (3) of the long-sized hardened steel material (2) held by the tool post (5).
