摘要:
Die Erfindung betrifft eine Schleudergussvorrichtung (1), umfassend eine drehbar gelagerte und angetriebene Welle (2), die drehfest mit einer Kokillenaufnahme (3) verbunden ist, wobei in der Kokillenaufnahme (3) eine Kokille (4) angeordnet ist, wobei Mittel (5) zur Erzeugung einer Luftströmung an mindestens einer Oberfläche der Kokille (4) und/oder der Kokillenaufnahme (3) vorhanden sind. Um eine verbesserte Kühlung auch ohne Einsatz von Kühlwasser zu erreichen, sieht die Erfindung vor, dass für die Luftströmung ein Strömungskanal (8) gebildet wird, der zwischen einer radial außenliegenden Oberfläche (9) der Kokille (4) und einer radial innenliegenden Oberfläche (10) der Kokillenaufnahme (3) verläuft, wobei die radial außenliegende Oberfläche (9) der Kokille (4) mindestens einen wendelförmig verlaufenden Steg (11) aufweist.
摘要:
The invention describes a brake disc production system and the products thereby obtained, featuring a cast iron melting phase and a subsequent plurality of phases in which a metal mould is made to rotate and is lined with a particular refractory material. There follows a phase in which the liquefied cast iron is removed from the furnace then poured into the rotating mould through a special opening. At this point, the mould is cooled by means of nozzles which spray water at the said mould's external surface, and the cylindrical element obtained at the end of the cooling phase is then extracted. Finally, a shot blasting phase is carried out in which all the residues are cleaned off the cylindrical element, followed by a phase in which the structural and mechanical characteristics of the said element are checked. Finally, the cylindrical element is cut into "slices" to realise the single discs.
摘要:
The tubular die (22) of a centrifugal casting device (20) of GNo. 30 or above is employed suitably and powder (P) is introduced while rotating, and an outer tubular body (14) composed of that powder (P) is provided. Subsequently, molten (LI) is introduced to the inner circumferential wall side of the outer tubular body (14) while sustaining rotation of the tubular die (22) thus forming an inner tubular body (12). The outer tubular body (14) functions as a cooling metal (chiller) when the molden (LI) is cooled and solidified. In place of the outer tubular body (14) composed of the powder (P), molten may be used for forming an outer tubular body or an outer tubular molding molded previously into tubular shape may be employed.
