ABSTRACT:
A novel metal tube corrugating die comprises a hollow die body with a plurality of die teeth in an internal cavity. The die teeth are flat with a curved edge extending diagonally into the die cavity providing a die corrugating tooth surface extending inward along a curved line. The die teeth are spaced uniformly around the interior of the die body. The die teeth are positioned somewhat on a helical line and are each tilted away from the other so that the planes of the individual teeth intersect substantially on the longitudinal axis of the die at a point foreward of a plane normal to the die body and passing through all of the die teeth. A mathematical equation expresses the optimum clearance between the die teeth. When a thin-walled, hollow tubing is inserted in the die, held against rotation, and the die body rotated relative to the tubing, the die teeth corrugate the tubing. Rotation of the die body corrugates and shortens the tubing according to the depth and the width of the teeth and the speed of die rotation.
