Abstract

PURPOSE: To produce a thin-walled spiral type hollow body from a C type section blank material of a linear shape without any creasing, buckling, etc. by curving said material while restraining its inside and outside surfaces.
CONSTITUTION: After a leading end material 1 is inserted into the spiral spacing between a mandrel 1 and a forming tool 12, a wire rope is welded to the leading end side, and a linear blank material W1 of a C-shaped section is welded to the terminal side. The rope is wound on a mandrel 1, and the leading end part is fixed to the mandrel 1 by a clamping device 21. When the driving device is started and the mandrel 1 is rotated by way of a pinion 9, a gear 9, a rotator 7, a rod 6 and an end plate 4, the linear material W1 is pulled continuously into the space between the tool 12 and the mandrel 1, whereby it is spirally curved. The intermediate product W2 which is spirally curved by the tool 12 is closed and mated at opening parts by a press-contacting roller 18, and is joined by a succeeding beam welding device 20, whereby it is made into a product W3 (hollow coil spring).
