摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing steel pipes by a simple method of making a spiral pipe even when it is a thin small diameter pipe below 50 mmϕ.
SOLUTION: When a steel strip is worked and formed into a spiral shape by making the steel strip pass through forming rolls and made into the spiral steel pipe by welding adjacent edges each other at weld points, one bar body having a circular cross section, which is extended in the axial direction of the pipe on the side of the inner surface of the pipe is used in place of an internal forming roll group composed of a plurality of forming rolls which are arranged inside a spiral-shaped formed pipe. It is made possible to remarkably reduce a formable diameter when making the pipe, which has been depended on the diameter of a roll supporting shaft with which the inner surface forming roll group has been mounted and held up to now.

摘要： PROBLEM TO BE SOLVED: To provide a method of forming a material having a channel section with a thickness in the range to an extent of 2.3-6 mm which is used for a structural material, for example, without exchanging forming rolls and adjusting the position in the axial direction of the rolls while using general-purpose roll-forming stands high in rigidity and with a simple structure.SOLUTION: This method is for forming the material having the channel section with a roll-forming apparatus in which the roll-forming stands having forming rolls 1, 2 mounted on upper and lower shafts supported at both ends are arranged in multistage. The material having the channel section is formed by using the rolls which are designed so that the material having the channel section which is largest in thickness among the materials having the channel section is formable. Also, in the latter half of a roughly forming region where the material having the channel section is formed into an approximately final shape, corner dimensions are corrected by using the forming rolls which are set properly to the thickness of the material having the channel section which is formed by a roll gap of a web and a flange part and the radius on the inside of the corner part sandwiched by the web and the flange and, thereafter, finish forming is applied for removing residual stress and securing the dimensional accuracy.
