Abstract
PURPOSE: To high-efficiently manufacture a short pipe with high quality, by welding butted two edges of a long size sheet material after being continuously bent into a cylindrical shape, by flattening this welded cylindrical pipe by a grooved roller, by shearing this flattened welded pipe into a specified length, and by expanding this short flat pipe to finish the purposed short pipe.
CONSTITUTION: A pipe-forming long sheet material 1 such as a hoop, etc., is fed to the rotating squeeze rollers 6 and is laterally bent so as to butt both of sheet edges, which are continuously welded by the welding torch 2; hereby, a long sized, cylindrically formed, and welded pipe is continuously fed forward. Next, this welded pipe is continuously flat pressed by a grooved roller 12 to form a continuous, flat and welded pipe 13 which is then sheared by the shear blade 14 into a specified length. This short flat pipe 15 is expanded by driving an expanding zig 16 into the pipe 15; hereby, the short pipe 17 of specified size is obtained.
