Patent

CA 2278298

The invention relates to a pressing facility (1) for compressing metal parts, in particular chips (3), consisting, for example, of Fe, Cu, Mg, or alloys of these elements or other metals with a low melting temperature, or alloys of these other metals, into homogeneous pressed parts. Said pressing facility comprises at least one pressing device with a pressing tool (5) formed by a tool housing (9), which forms a mould cavity (8) and comprises a guiding system for a press element (7) which can be adjusted via a drive device (6), as well as an inlet opening (28) for the chips (3) in the tool housing (9). In addition, a compression channel (18) is positioned adjacent to a frontal face of the press element (7) facing the mould cavity (8), opposite said mould cavity (8) in the direction of a passage surface (15) for a strand of material (2).

L'invention concerne un dispositif de pressage (1) pour comprimer des parties métalliques, notamment des copeaux (3), constitués par exemple de Fe, Cu, Mg, ou bien d'alliages de ces éléments ou encore d'autres métaux à bas point de fusion, ou bien leurs alliages, en vue d'obtenir des comprimés homogènes. Ce dispositif de pressage comporte au moins un système de pressage avec un outil de pressage (5) formé par un carter d'outil (9), cet outil constituant une empreinte (8) et comportant un système de guidage destiné à un élément de pressage (7) réglable par l'intermédiaire d'un dispositif d'entraînement (6), un orifice d'entrée (28) destiné aux copeaux (3) étant ménagé dans le carter d'outil (9). En outre, un canal de compression (18) adjacent à une face frontale de l'élément de pressage (7) située en regard de l'empreinte (8) est disposé, en face de ladite empreinte (8) en direction d'une surface de passage (15) d'un boudin de matière (2).
