The equipment forms metal profiles on a stretch-bending machine on which a profile to be formed is held at its end by jaws connected to stretching rams and to a system for bending it against a convex punch member fixed to a toolholder table of the machine. The equipment includes a die member which is pressed against the punch member, once the profile has been bent against the punch member. An elastic material mandrel is placed inside the profile and the mandrel is compressed-expanded so that it presses the profile against internal surfaces of the punch member and of the die member when closed one against the other.

Equipment for forming metal profiles

A structure for supporting forming tools in a machine for forming metal sheet by stretching, the structure comprising n juxtaposed table segments mounted in a stand of the machine, with at least n-1 of said table segments being individually fitted with means enabling said segment to be placed either in a high, working position, or else in a low, rest position.

Structure for supporting forming tools in a machine for forming sheet

A stretch-forming machine for forming about a forming die, the machine comprising two jaws situated longitudinally on either side of the die, each jaw being connected to a fixed portion via drive means enabling each end of the jaw to move substantially in a plane perpendicular to the jaw in its rest position and to move in any direction within the plane. The die is fixed on a base connected to a table of a fixed frame, the table being situated at ground level, and the machine includes vertical guide means for the middles of the jaws, the jaws being connected to the drive means without any possibility of rotating relative to the means about a longitudinal axis.
