摘要： A method and an apparatus for supporting a roll molding machine stand and a method for controlling said apparatus wherein the height and inclination angle of a cluster of rolls in which a plurality of sets of rolls are continuously arranged as with side rolls of a roll molding machine like a pipe mill can arbitrarily be set and wherein the gap between the rolls can also be reduced, being characterized in that a pair of cluster platform frames each mounted with a plurality of side rolls held by a roll bracket and on which a common bed is placed are carried by links acting as jacks, that the end positions of said links are fixed such that they form an arbitrary triangle on the surfaces of said platform frames and said bed, that the length thereof is measured by means of a linear encoder disposed along said link, and that current positional information and a target positional information are compared with each other and calculated based on the results of the measurements that are transformed into a Cartesian coordinate system by a computer so as to alter the length of each of said links for adjustment of the length in extending or contracting fashion, whereby the rolls can freely be set with respect not only to vertical and horizontal directions relative to the molding path line but also to an abutment direction relative to a material, and further even if a horizontal roll that is rotationally driven is disposed inside a group of side rolls, the gap between the side rolls is not increased. Thus, there is no molding deterioration generated in buckling of an end of a material to be molded, and therefore the present invention is most suitable for production of thin-wall pipes which reject any distortion.

摘要： A method of forming a welded pipe with high dimensional accuracy on a production line for the welded pipe, wherein a metal web having a predetermined width is continuously roll-formed and welded, and more particularly for bending the end portions of the metal web with high accuracy, and a forming stand therefor. A pair of top and bottom forming horizontal rolls or a forming horizontal roll, each split into two segments in the metal web width direction, can be each adjusted in position in the widthwise direction, and further, each split top roll segment has a construction capable of turning about and being fixed on a shaft disposed in the vertical direction. Further, in order to maximize the effect of the present invention, the direction of turning and the angle of turning are restricted. With the above-described arrangement, edge bending can be performed without impairing the accuracy in the wall thickness of the material to be formed, and further, common use of rolls for forming metal webs into pipes with different diameters is possible.

摘要： A forming roll for pipe mills, which is used to form pipes such as a seam-welded pipe by means of the continuous roll forming, and to a method of and an apparatus for forming strip material by using this forming roll. The forming roll has an involute based on a polygon consisting of a plurality of preset sides so that the cross section of the roll surface has a shape of curved surfaces having radii of curvature which vary continuously with a predetermined relationship with one another. Accordingly, the curved surfaces having various radii of curvature can be set on the surface of the roll depending upon various diameters of pipes to be produced so that, for example, in an apparatus for forming the end portion of the strip material, the distance between a pair of the forming rolls can be changed according to the width of the strip material and the direction of the rolls can also be adjusted so as to properly abut against the strip material, whereby the end portion of the strip material is formable into the desired shape relying upon the forming rolls having the curved surface portion required for forming the pipes with the desired diameter. If these rolls are used as horizontal rolls, side rolls, or the like in each stage of the forming operation, the number of steps of forming rolls can be reduced. Moreover, the forming operation for the production of steel pipes having various diameters including small to large ones and various wall thicknesses can be carried out without replacing the forming rolls.

摘要： A roll forming machine which includes an outboard housing (96) having dual turrets (98-99), each turret carries a pair of rotatable arbors (113-114-115-116) which can carry forming rollers (117-118). The outboard housing is slidable along guide rails between on-line and off-line positions. In the off-line position the turrets may be indexed to bring the second pair of arbors into a working alignment and thus reduce changeover and down time of the roll forming line.

The mandrel (11) being mounted between support frame ends (24, 25) and on a single pressure roller (15) mounted beneath the mandrel (11) and adapted to contact the surface of the plate and apply a squeezing force against the plate and mandrel (11) during a rolling operation, the pressure roll (15) being laterally movable relative to the centreline of the mandrel depending upon the location of the gripper rib (14) in the region of the roller (15) so as not to foul the gripper rib (14) yet applying said squeezing force to said plate as required. A mandrel (11) having an adjustable taper angle is disclosed as an adjustable mandrel support member (2, 25) and mandrel journal (26) to accommodate variable mandrel diameters and angles of taper.
