摘要： An improved method of forming a skelp into a rounded tubular form in the preparation of an electric resistance welded steel pipe. Different from conventional methods, the skelp is bent in the initial and intermediate forming stages within a limited region alone along the centerline thereof to have a U-shaped flower pattern. Thereafter, the edge portions of the bent skelp are bent in the upstream fin pass rolls to have a curvature of at least 80% of the final curvature with simultaneous overbending in the boundary regions on both sides of the side portions of the rounded skelp. Finally, the rounded skelp is pressed down in the direction to decrease the vertical diameter to bulge out in the transverse direction with simultaneous unbending the overbent portions into the final curvature.

摘要： Disclosure is made of a process for reduction and sizing of welded pipes, whereby a pipe is reduced in diameter in passes formed by rolls of alternating horizontal and vertical stands. The weld zone is deformed by portions of roll passes of an equal curvature. Disclosure is further made of a mill for effecting the above method, which comprises alternating horizontal and vertical stands with rolls whose working surface is defined by arcs of at least two radii. The radius of at least one of said arcs is equal to the radius of the roll welding pass. The apices of said arcs of an equal radius are in the same plane extending through the longitudinal axis of the mill and on the line of motion of the weld.

摘要： An assembly for maintaining alignment of a metal strip between successive roll forming means in an apparatus for forming a metal tube is disclosed. The apparatus includes a first set of roll forming means, which form the flat strip of metal into a generally U-shaped cross-sectional configuration, and a second set of roll forming means which form the U-shaped strip into a generally annular cross-sectional configuration. The assembly includes a pair of cylindrical hold down rolls which engage the guide respective marginal edge portions of the U-shaped strip into the second set of roll forming means. The cylindrical hold down rolls are rotatably supported by appropriate shaft means. The end portions of each of the shaft means are supported by vertically adjustable bearing means for adjusting the angular disposition of the shaft and the associated cylindrical hold down roll with respect to the marginal edge portions of the formed strip of metal. Since the distance between each cooperating pair of bearing means changes during the angular disposition of the shaft, at least one end of the bearing means must allow the shaft to slide telescopically therein when the angular disposition of the shaft is changed.
摘要翻译：公开了一种用于在用于形成金属管的装置中的连续的辊形成装置之间维持金属带的对准的组件。该装置包括第一组辊形成装置，其将扁平的金属条形成为大致U形的横截面构造;以及第二组辊形成装置，其将U形条形成为大致环形的横截面，截面配置。该组件包括一对圆柱形压紧辊，其将U形条的相应的边缘部分引导到第二组辊形成装置中。圆柱形压紧辊由适当的轴装置可旋转地支撑。每个轴装置的端部由垂直可调的轴承装置支撑，用于相对于所形成的金属条的边缘部分调节轴和相关联的圆柱形压紧辊的角度布置。由于每个协作的一对轴承装置之间的距离在轴的角度配置期间改变，所以当轴的角度配置改变时，轴承装置的至少一端必须允许轴可伸缩地滑动。

摘要： A fin pass roll for use as a single roll or as pairs of mating forming rolls for bending a flat metal strip into a desired tubular shape or a tube form. The fin pass roll is split into three sections; that is, a fin roll having a fin and fin side rolls in such a way that the fin roll may have arcuate caliber profile which are extended to both sides from the fin and merge with the arcuate caliber profile of the adjacent fin side rolls. The fin side rolls are rotatable in unison with a drive shaft, but the fin roll is so constructed and arranged as to be rotatable independently of the drive shaft and hence the fin side rolls.

THE MACHINE UTILIZES COOPERATIVE ROTARY DIES TO SHAPE AND FORM THE DUCT IN A CONTINUOUS OPERATION TO A LENGTH EQUAL TO THAT OF THE SHEETS SO THAT RECTANGULAR DUCTS OF ANY DESIRED LENGTH CAN BE PRODUCED IN AN AUTOMATIC OPERATION BY MERELY INSERTING INTO THE MACHINE A PRE-PREPARED ROLL COMPRISED OF A PAIR OF SHEETS OF METAL OF THE DESIRED LENGTH, THE SHEETS ENTERING THE MACHINE AT ONE END AND

LEAVING THE SAME AT THE OTHER END IN THE FORM OF A CONTINUOUS RECTANGULAR DUCT.

摘要： Changing of a horizontal roll in a horizontal roll stand involving readjustment of an amount of pressing is to be done readily and promptly. In order to achieve this, a horizontal roll stand 10 with a pair of built-in upper and lower horizontal rolls 11 is configured to retreat toward one side across a forming line. A fixed stand 40 stands upright on a counter-retreating side of the forming line. An overhang part 42 of the fixed stand 40 jutting out over the forming line is provided with a pressure device 43 that applies a pressing force to the horizontal rolls 11. The horizontal roll stand 10 includes a horizontal roll housing 12 with an opened top, receives the pressing force from the pressure device 43 via the opened top, and retreats to the outside of the forming line while the pressure device 43 is left on the forming line. The overhang part 42 of the fixed stand 40 is engaged with the horizontal roll housing 12 of the horizontal roll stand 10 to support the horizontal roll housing 12 in the forming line.
