Abstract
Wire-drawing machine for metal wire with dry lubrication, comprising a tocarrying device provided with: a tubular body having a cavity for containing and fixing a die, extending from an entry end to an exit end for the metal wire inside the tubular body; a support for the tubular body on which the latter is coaxially mounted in a rotatable manner so as to rotate upon operation of associated actuator means, said support being provided with a fluid cooling chamber for the die; a container for powdery lubricant arranged above the support and connected to the tubular body so as to rotate about the metal die, imparting to the powdery lubricant a helical movement towards the die, thereby lubricating the metal wire before it enters the die.
Claims18
Wire-drawing machine for metal wire with dry lubrication, comprising at least one tool-carrying device provided with:
- a tubular body having a cavity for containing and fixing at least one die, extending from an entry end to an exit end for the metal wire inside the tubular body;
- a support for the tubular body, on which the tubular body is rotatably mounted so as to rotate upon operation of associated actuator means so as to cause rotation of the die, rendering uniform the wear thereof caused by the metal wire, said support for the tubular body being provided with a fluid cooling chamber for the die;
- a container for powdery lubricant associated with the support for the tubular body so as to lubricate the metal wire before it enters the die, wherein said lubricating container is arranged above the support for the tubular body and is connected to the tubular body so as to rotate together therewith about the metal wire, imparting to the powdery lubricant contained therein a helical movement towards the die.
