In the forming step of the 24st upper and lower forming rollers as the fourth stress removing means, in order to remove the stress generated in the third rib from the upper side of the second rib bending section to the third rib bending section of 75 mm width direction standard The lower forming roller middle forming roll is set to 62.9mm of upper and lower forming rollers and exceeds the proportional limit.The lower forming roller middle forming roll is R 428.11mm arc width 71.97mm and the outer forming roller of the upper forming roller which is 116mm outer diameter. The lower portion of the lower forming roller 16 is set to 75.07 mm, but the middle portion of the lower forming roller to be welded to the transverse outer width is maintained at 85.51 mm, and the height of the lower side forming portion to be 86.84 mm to be welded to the third rib bent portion. The intermediate forming roller is composed of R 469.10mm arc width 75mm and outer diameter 116mm to finally remove the proportional limit stress that occurs in the 90 ° bend of the tertiary rib. It is raised.

As described above, the upper and lower forming rolls (17; 16) for each step of Experimental Example 1 in preparation for the preferred embodiment of the present invention increase the bending angle of each rib in units of 15 ° so that the overall molding process length according to a total of 18 steps. Was 5,070 mm, which is less expensive to manufacture than the embodiment, but the deformation force generated in the first, second, and third ribs was the most severe, and the frictional heat was so severe that the rigidity of the product due to plastic deformation decreased.

On the other hand, the upper and lower forming rolls (17; 16) of each step of Experimental Example 2 increases the bending angle of each rib by 10 ° unit, the total molding process length according to a total of 27 steps is 8,000 mm, which is higher in equipment manufacturing cost than the embodiment There was this.

On the other hand, the frictional heat generated during the forming step is not significantly different from the embodiment, but the deformation force due to the stress generated in the first, second and third ribs is pointed out as a problem, and finally in the embodiment of the present invention The whole roll forming process including the means is reduced to the 24th to reduce the equipment manufacturing cost and increase the completeness of the product.
