Title (EN) DEVICE FOR STRAIGHTENING OF PIPES
(FR) DISPOSITIF DE REDRESSEMENT DE TUBES
Abstract: front page image
(EN)By straightening of bent pipes a device with two bases is used, which bases are placed on one side of the pipe on each side of the bending, a third base being placed on the bending on the other side of the pipe, i.e. on the outside of the bending. In order to straighten road sign posts that are bent at the surface of the earth a device is used that comprises a base (2, 3) in two parts spanning the bent pipe (1) on one side of the bending of the pipe (1), which base (2, 3) is connected to one end of a bar (11), which is pivotally fastened at the other end to a piston rod (10) in a working cylinder (9). The working cylinder (9) is pivotally fastened to a corner (8) of a triangular straightener (7, 14, 15) another corner (6) being pivotally fastened to one part of the base (3), and the side (7) opposite this corner (6) bearing a thrust block or roller (5), which presses against the other side of the bending of the pipe (1).
(FR)On utilise pour redresser des tubes courbes un dispositif possedant deux bases, placees d"un cote du tube de chaque cote de la courbure, une troisieme base etant placee sur la courbure de l"autre cote du tube, c"est-a-dire sur le cote exterieur de la courbure. Pour redresser des poteaux de signalisation routiere courbes a la surface du sol on utilise un dispositif comprenant une base (2, 3) en deux parties chevauchant le tube courbe (1) du cote de la courbure du tube (1), cette base (2, 3) etant connectee a une extremite d"une tige (11), fixee de maniere pivotante a l"autre extremite d"une bielle de piston (10) dans un cylindre de travail (9). Le cylindre de travail (9) est fixe de maniere pivotante a un coin (8) d"un redresseur triangulaire (7, 14, 15), un autre coin (6) etant fixe de maniere pivotante a une partie de la base (3), et le cote (7) oppose a ce coin (6) soutenant un rouleau ou bloc de poussee (5), qui appuie contre l"autre cote de la courbure du tube (1).
