Abstract

L'invention a pour objet une presse à refouler les extrémités de tubes. Des demi-matrices inférieures 7, 7' et supérieures 8, 8', utilisables successivement sont montées côte à côte symétriquement par rapport à l'axe général du piston de presse et des cales latérales allongées 11, 12, 15, 16, sont prévues avec une possibilité de réglage en hauteur. L'invention permet d'effectuer sur une même presse deux opérations successives de mise en forme d'une extrémité d'un tube.The subject of the invention is a press for upsetting the ends of tubes. Lower 7, 7 'and upper 8, 8' half-dies, which can be used successively, are mounted side by side symmetrically with respect to the general axis of the press piston and elongated lateral wedges 11, 12, 15, 16 are provided. with a possibility of height adjustment. The invention makes it possible to carry out on the same press two successive shaping operations of one end of a tube.
