摘要： PURPOSE:To form a band steel plate to a desired sectional shape by one pass, by passing the band steel plate through the inside of a caliber formed by one upper roll, plural lower rolls and a shoe whose bending angle is varied. CONSTITUTION:When a band steel plate of a material is passed through a molding device, the band steel plate 8 is pressed down by an upper roll in a caliber constituted of a bending surface 9 of a shoe 7, and a lower roll 5, while it passes through from the first lower roll 5 to the final lower roll 5, and a bending angle of the flange part becomes large continuously. In the caliber of the final lower roll 5, the flange part is bent to right angles, and lightweight shape steel is obtained. Subsequently, between each lower roll, the material band steel plate goes forward while being hold-bundled by the bending surface 9 of the shoe.

摘要： PURPOSE:To prevent lap occuring in an edge part by guiding a blank material of square-shaped tube, which is corner-bended to a welding roll having circular-arc- shaped upper rolls and butt-welding said material. CONSTITUTION:A blank material 5, which is corner-bended in the processes up to a fin-path-roll 9 and is formed into an open section of roughly square-shaped, is sent to welding rolls 10 in the next position. The material 5 is pressed from the periphery by the welding rolls 10, 15, whereby upper rolls 15a, 15b, having a radius of curvature R, in cooperation with the other rolls on 3 sides, keep the material 5 in the pressing status. Particularly, the overlap of faces 21, 22 into the tube is prevented, and the lap occurring in a welded face is eliminated, by the face-pressure through the upper rolls 15a, 15b. Then, butting the edge of an opening on the upward side face is butted and electrically welded, thereby a square-shaped metallic tube 12 having a welding juncture 11 on the upward side face is made.

摘要： PURPOSE: To change the type of product to another type of a desired size without detaching a forming roll and a spacer, by using a specific set collar when the type of product is changed by an arbor method in roll forming of shape steel, etc.
CONSTITUTION: When a type of product is changed from channel steel 10-A to channel steel 10-B in roll forming of a strip steel a roll 1A is inserted into an arbor 11 and, at the same time, is held by a dimension fixing set collar 30 and a fastening set collar 20. Both the set collars have projections on the inner circumference, respecitvely, and the projections slide in grooves 13-1 and 13-2 installed in the direction of the circumference and the axis of the arbor 11. When the type of steel is changed from 10-A to 10-B, a fastening nut 25 is loosened and the projection 20 of the set collar 20 is rotated along the groove 13 in the direction of the circumference of the arbor 11. Then, the projection 21 is fitted into a groove 12 and slided in the groove 12. Thus, the roll 1
a can be moved in the direction of the axis of the arbor 11. Then, the roll 1A is fixed, by fixing the projection of the set collar 30 in the groove 13 in the direction of the circumference of the channel steel 10-B.

摘要： PURPOSE: To manufacture a square metallic blank pipe having a weld metal of good quality at its weld zone, by preforming a square pipe blank, after passing a corner bending process, with an upper side forming roll and a fin pass roll, and by welding with a welding roller having a circular arc shaped roll profile, at manufacturing a square metallic blank pipe.
CONSTITUTION: A metallic blank sheet 1 is formed into a pentagonal cross section with an unclosed apex by bending the corner parts; this blank pipe 1 is processed by an upper side forming roll 2F in order to form an upper side 1a into an outward convex circular arc of a curvature R
1 by applying a mandrel roll 31 from the inside. The blank pipe is then fed to a fin pass roll wherein the bending angle of the square blank pipe 1 is further enlarged, and at the same time, the end planes on both side edges are forced to touch at the side plane of a fin roll, and a compression force is applied from outside to the outer surface of the blank pipe for giving it a 0.5W1.5% reduction. Thus preformed blank pipe is then passed through a welding roll and is electrically seam welded; as a result, an excellent welded seam is formed, and a square metallic pipe with an excellent weld metal at its weld zone is finished.
