Abstract

A B R E G E Presse pour la fabrication de produits moulés ou emboutis comprenant un outil de presse (3) fixé à une extrémité d'un cylindre mobile (2). Ce cylindre mobile (2) est monté coaxialement à l'intérieur d'un cylindre fixe de guidage (4) fixé de manière suspendue coaxialement à l'intérieur d'un cylindre (5) formant l'enveloppe extérieu-re de la presse. La presse comprend une cloison mobile (8) définissant une première chambre à volume variable, huit vérins hydrauliques (11a à 11h) à pistons différentiels libres (12a à 12h) disposés en couronne autour du cylindre central (2). L'enveloppe extérieure (5) comprend un élar-gissement (23) pourvu d'au moins un alésage (44) dans lequel sont disposés des moyens à explosion pour provoquer le déplacement de l'outil de presse (3) quand la presse est utilisée comme une presse pneumatique là explosion combinée. La presse est d'un encombrement réduit, et peut être adap-ter pour la fabrication d'articles différents à des cadences de travail variées par des modifications simples et rapides. Figure 1.-
