Title
(EN) WIPING UNIT FOR RAM OF BODYMAKER
(FR) RACLEURS POUR MARTEAU DE MACHINE A FORMER DES CORPS METALLIQUES
Abstract
(EN)
A bodymaker (15) that transforms shallow metal cups (16) in elongated can bodies includes a reciprocated ram (20) which, during its forward stroke, drives the cups through a set of graduated circular dies (22). Ring-shaped wipers (83, 84, 85) engage the outer cylinder surface (70) of the ram and are arranged so that a first of the wipers scrapes tool coolant from the ram as the latter moves rearward and a second of the wipers scrapes hydraulic bearing fluid from the ram as the latter moves forward. The wipers are provided with flexible flaps (89) that are in relatively low pressure frictional engagement with the ram resulting in only a very low temperature rise for the wipers to increase operating life thereof at production rates of approximately 400 per minute for cans of 2.5 inch diameter.
(FR)
Machine (15) à former des corps métalliques, transformant des coupelles de métal peu profondes (16) en boites allongées et comportant un marteau à mouvement alternatif (20) qui, pendant sa course en avant, force les coupelles dans un jeu de matrices circulaires échelonnées (22). Des racleurs annulaires (83, 84, 85) en contact avec la surface cylindrique extérieure du marteau sont agencés de sorte qu'un premier racleur racle le liquide de refroidissement sur le marteau lors de la course arrière de ce dernier et un deuxième racleur racle le fluide des paliers hydrauliques du marteau pendant la course en avant. Les racleurs sont munis de volets souples (89) mis en contact à friction relativement faible avec le marteau d'où une très faible élévation de température des racleurs, dont la durée de vie se trouve sensiblement prolongée pour une cadence de production de 400 corps/minute pour des boites de 2,5 pouces de diamètre.
