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.
