Abstract
PURPOSE: To produce zigzag heat transfer pipes which are flattened in the straight parts and are bent in the circular part continuously and efficiently by bending 180° the circular part of the pipes of which the sections are manufacutred alternately with the circular part and the flat part.
CONSTITUTION: Flat part 5 and cylindrical part 6 are alterntely fromed to blank pipes 2 by intermittently narrowing or widening the inter-shaft distance of flattening rolls 4 at predetermined cycles. Following to this, the part 6 is alternately stopped in the position of the 1st benging roll 9 and the 2nd bending roll 7. The 1st wiper shoe 10 performs the operations of approaching A, 180° bending B, parting C and resetting D in the roll 9 position and the 2nd wiper shoe 8 does so in the roll 7 position, respectively, thereby bending the part 6. Here, 11 denotes the bending part, and 12 the boundary part between the flat part 5 and the part 6. During bending with the shoe 8, the roll 9 is moved in the axial line direction shown by the arrow. Next, upon ending of required times of zigzag bending, the blank pipes are cut with a cutting tool 14 and this completes one cycle.
