Title (EN) METALWORKING APPARATUS WITH LUBRICATING AND COOLING DEVICE
(FR) APPAREIL DE TRAVAIL DES METAUX AMELIORE
Abstract:
(EN) A metalworking apparatus comprising a drive section and a die pack assembly. The drive section includes a reciprocally movable ram which is movable through forward working and rearward return strokes through the die pack assembly. The drive section is lubricated by a gear oil based on polyglycol, and the die pack assembly includes a water-based coolant. Seals are used to prevent cross-contamination of the gear oil and coolant. However, contamination does occur. The present invention therefore provides a removal apparatus for removing any polyglycol from the gear oil that has contaminated the coolant. The contaminated coolant is removed from and then returned to the die pack assembly on a continuous basis. The removal apparatus preferably includes a separation tank (6) which separates the polyglycol from the coolant. The removal apparatus is preferably a portable system.
(FR) L'invention concerne un appareil de travail des métaux qui comporte une partie d'entraînement et un ensemble de matrices. La partie d'entraînement comprend un vérin à mouvement alternatif, qui imprime un mouvement par accoups avant et arrière à travers l'ensemble de matrices. La partie d'entraînement est lubrifiée par un huile d'engrenages à base de polyglycol, et l'ensemble de matrices comprend un réfrigérant à base d'eau. Des joints sont utilisés pour empêcher une contamination croisée de l'huile d'engrenages et du réfrigérant. Malgré ces joints, une contamination peut survenir. La présente invention comporte par conséquent un appareil d'élimination conçu pour éliminer le polyglycol de l'huile d'engrenages ayant contaminé le réfrigérant. Le réfrigérant contaminé est retiré de l'ensemble de matrices et renvoyé à celui-ci en continu. L'appareil d'élimination comprend, de préférence, un réservoir de séparation qui sépare le polyglycol du réfrigérant et est, de préférence, sous forme de système portatif.
