ABSTRACT:
A tube cut-off apparatus includes a horizontally moving scarfing blade which opens up the top of a tube permitting a vertical moving cut-off blade to move through the opening and finish cutting the tube. An upper die plate supports the vertical cut-off blade and a locking cam arrangement includes spaced vertically extending cams which provide for longitudinal movement of clamping slides in turn opening and closing jaws of die blocks which support the tube to be cut. A horizontally movable slide member carries a scarfing blade which cuts horizontally the upper tube portion and moves out of the way to permit the vertical blade to shear through the tube. The scarfing and clamping arrangement is actuated entirely by the mechanism on one side of the apparatus with the cams performing the clamping function as well as the actuation of the slide member. The sliding blocks and associated clamping members are all supported on a T-shaped rail and the moving elements on the rail are confined and maintained in position by a retaining frame which surrounds the elements, the said frame having limited horizontal movement.
