Abstract

Portable tube bending machine and the like that employs an internal support or mandrel that has a frame that comprises together with a pair of plates between which a bending former is mounted having a series of forming surfaces a pair of rigid legs with the plates forming for example the rear legs of the frame a pair of legs mounted to pivot around the plates to form for example the front legs of the frame when it is extended a series of rods mounted parallel to the rigid parts and forming supports for the pipes to be bent, the rods having profiled ends that constitute internal mandrels a clamping device that can rotate forming and that consists of a block that presents complementary surfaces to the forming surfaces of the former and a movable cam to make the block grip the tubes between it and the bending former.
