PRESSE A REFOULER LES EXTREMITES DE TUBES

The invention relates to a press for upsetting the ends of tubes, having longitudinally split upsetting shells, each of which is arranged on a moving carrier. In this arrangement, one upsetting shell on one carrier together with an upsetting shell on the other carrier forms a die which surrounds the end of the tube concentrically to the axis of the latter. In order to achieve easier exchangeability and accessibility of the die and hence shorten the cycle time, it is proposed that the carriers be designed as pivoted levers which are mounted so as to be pivotable about axes parallel to the axis of the tube and, at their ends, carry the upsetting shells. LA PRESSE A REFOULER, SELON L'INVENTION, EST MUNIE DE CUVETTES DE REFOULEMENT DIVISEES LONGITUDINALEMENT DONT AU MOINS DEUX SONT DISPOSEES CHAQUE FOIS DANS UN SUPPORT MOBILE. L'UNE DE CES CUVETTES FORME AVEC UNE AUTRE CUVETTE, UNE MATRICE ENTOURANT L'EXTREMITE DU TUBE CONCENTRIQUEMENT A L'AXE DU TUBE. LES SUPPORTS SONT SOUS LA FORME DE LEVIERS PIVOTANTS 1 MONTES DE MANIERE A POUVOIR PIVOTER AUTOUR D'AXES 3, 4 PARALLELES A L'AXE DU TUBE ET PORTANT, A LEURS EXTREMITES, DES CUVETTES DE REFOULEMENT I, II.CETTE PRESSE SERT AVANTAGEUSEMENT A REFOULER LES EXTREMITES DE TUBES.
