The invention pertains to a mechanism for guiding and controlling the clearance of slides of single or multiple slide mechanical presses. A novel gib mount assembly with at least one substantially flat bearing surface is utilized adjacent a portion of a slide to control clearance and undesired movement of the slide while sealing press lubrication oil from the area of the press where products are produced. Between the bearing surface of the gib mount and slide is created a squeeze seal oil film region to assist in controlling the clearance therebetween. One or more vacuum pressure regions are created about the boundaries of the oil film region to suction and capture any oil escaping from the oil film region thereby preventing oil contact with the stamped parts or products.

Cette invention concerne un mécanisme de guidage servant à guider et à régler le jeu des coulisseaux de presses mécaniques à coulisseau simple ou coulisseaux multiples. Un support de lardon novateur comportant au moins une portée plate est utilisé à côté d'une partie du coulisseau pour régler le jeu de celui-ci et empêcher son déplacement au-delà des limites admises tout en empêchant l'huile de lubrification de la presse de parvenir à la zone où sont réalisées les pièces façonnées. Entre la portée du support de lardon et le coulisseau est créée un film d'huile amortisseur aidant à régler le jeu entre ces deux éléments. Une ou plusieurs zones de dépression sont créées aux limites du film d'huile pour aspirer et capter toute huile s'échappant de la zone d'amortissement fluide et susceptible de mouiller les pièces ou produits matricés.
