Claims

[Scope of utility model registration request]

A steel plate is bent using a press at positions corresponding to the four corners of a square steel pipe to form a molded product with a shape approximating the square steel pipe, and then this molded product is press-formed into the regular shape of the square steel pipe, and the left and right flanges are butted together. This forming roll machine is installed in the press-forming process of the square steel pipe in a square steel pipe manufacturing facility that manufactures square steel pipes with welded ends, and the upper roll presses the upper surfaces of the left and right flanges of the molded product. A forming roll machine for square steel pipe manufacturing equipment, characterized in that it is configured to be able to be raised and lowered separately from squeeze rolls that press the sides.
