Abstract

Invention refers to a procedure and a device for shaping metal helical profiled pipes by means of a mandrel in plastic deformation of any shape of the cross section. The procedure for shaping relates to thin wall metal pipes of any diameter. Shaping is achieved by means of the mandrel (1) and wheels (3). The main tool is the mandrel (1) which determines the final shape and pitch. For the fulfillment of the procedure is required a device for moving the mandrel (1) and holding on to the wheels (3). Manufacture of different shapes and pitches demands making out the various mandrels (1). The shape and length of the pipe (2) have no logical limitations. Carrying out the procedure is done by moving the mandrel (1) through the pipe (2) toward the unprocessed part of the body (2) and the thrust of the wheels (3) onto the mandrel (1) over the pipe (2). Shaping is carried out in intervals: rolling the wheels (3), moving the mandrel (1) up to the end of the length of the pipe (2).
