Abstract

PURPOSE: To obtain the sections with hollow parts having high strength and suited for wiring and transportation by bending and forming metal pipes to sections of required sectional shapes through roll forming by way of the flat plates which are simultaneously formed with hollow parts of suitable shapes in required parts.
CONSTITUTION: A steel pipe 1 of a suitable diameter is inserted into the gap 6 of the upper and lower rolls 7a, 7b of a forming device 5 and is run to be passed through roll groups b thru c, whereby it is subsequently flattened and is finished to a flat plate having a hollow part 4 of a desired shape. Next, the flat plate 2 is passed through continuous forming groups and is finished to a section 3 which the channel-form follow part 4 in which walls 12, 12 are erected at a right angle by the cooperation of the upper and lower rolls 7e, 8e and left and right rolls 13, 13. The sectional shape of the sections is not limited to the above. The hollow part 4 provides the effect equivalent to that of reinforcing ribs. In this way, the section with hollow part of considerably increased strength is obtained. This is suited for electric wiring and fluid transportation and eliminates the need for installation of ducts of conventional methods.
