Abstract

La machine de formage comprend un bâti (1) qui s'étend longitudinalement de part et d'autre d'un outil (3). Cet outil (3) est disposé transversalement à la partie centrale du bâti (1).The forming machine comprises a frame (1) which extends longitudinally from on either side of a tool (3). This tool (3) is arranged transversely to the part central frame (1).

Des mâchoires (12), disposées de part et d'autre de l'outil, sont actionnées pour chacune d'elles par deux paires de vérins dont des vérins quasi-horizontaux (13) et des vérins quasi-verticaux (14).Jaws (12), arranged on either side of the tool, are actuated to each of them by two pairs of jacks including quasi-horizontal jacks (13) and quasi-vertical cylinders (14).

Chaque mâchoire (12) comporte un point (32) qui est mobile dans un plan longitudinal vertical, et ce point (32) est maintenu dans ce plan au moyen de l'un des vérins de manoeuvre de ladite mâchoire et en particulier un vérin vertical (14).Each jaw (12) has a point (32) which is movable in a plane longitudinal vertical, and this point (32) is maintained in this plane by means of one of the actuating jacks for said jaw and in particular a vertical jack (14).

Ce vérin de guidage (14) comporte des patins (26) disposés sur l'extrémité supérieure de son cylindre (22), et ces patins glissent sur des plaques (29) verticales longitudinales solidaires du bâti (1).This guide cylinder (14) has pads (26) arranged on the end upper part of its cylinder (22), and these pads slide on vertical plates (29) longitudinal integral with the frame (1).

Le berceau (15) de la mâchoire (12) est articulé sur l'extrémité de la tige du vérin de guidage (14B), au moyen d'un axe (31) qui est perpendiculaire à l'axe (33) dudit vérin (14) et dont l'axe se situe dans le plan de guidage.

Figure 00000001
The cradle (15) of the jaw (12) is articulated on the end of the rod of the guide cylinder (14 B ), by means of an axis (31) which is perpendicular to the axis (33) of said cylinder (14) and whose axis is in the guide plane.
