Abstract: A portable tube-bending machine for receiving a length of tubular material 10 and repeatedly crimping the length of tubular material 10 to form an elbow. It includes a so-called toggle assembly 24, a carriage assembly 70 and an operating shaft assembly 50, all being movably mounted to a framework assembly 15. Operating shaft assembly 50 is operatively connected to sequentially actuate movement in toggle assembly 24 and carriage assembly 70. Outer die elements 28, 29, and 30, are movably mounted to toggle assembly 24 and adapted to crimp tubular material 10 by crimping it against an inner die 26. Carriage assembly 70 engages tubular material 10 and induces lengthwise movement relative to framework assembly 15 along the axis of the length of the tubular material 10.

Abstract: A tool including two flat parallel flanges (2 and 3), defining between them a space (4) which corresponds to the thickness of a cutting blade (5) and including two symmetrical slots which have profiles that are roughly identical to that of a gutter (7) so as to constitute a guiding cradle for cutting the gutter by operation of the cutting blade (5) between flanges (2 and 3). The guiding cradle is defined by slots delimited in an upper zone by a convex contour (6b) of a fixed part of the flanges, and in a lower zone by the concave contour (6a) of a movable part, so that a movable part can be articulated at one of its ends around a fixed axis of rotation (8) like a jaw (9) in the open position (0), to allow free passage of the gutter (7) and in the closed position (F) constitutes a fixed support for cutting.
