Abstract

L'invention concerne l'usinage des métaux par déformation. Le marteau faisant l'objet de l'invention est caractérisé notamment en ce que, dans la tige 11 du piston 7, du côté de l'espace d'estampage, est prévu un orifice central de guidage rendu étanche du côté de la chambre de travail 5 et dans lequel se trouve la frappe 13, la valeur de la course dudit piston étant supérieure à la distance entre l'étampe 18 et l'extrémité inférieure de la tige, de sorte que, dans la position extrême inférieure du piston 7, sa tige forme autour de la frappe 13, conjointement avec la surface de l'étampe 18, une zone fermée dans laquelle s'effectue la déformation de l'ébauche de départ. L'invention assure notamment le formage rapide de pièces en métaux et alliages difficiles à déformer.
