摘要： The invention relates to a roll bending device for the control of profile and flatness in the rolling of metal plates or strips. In particular the invention relates to the well known principle of roll bending by using hydraulic cylinders to modify the load distribution between rolls of a rolling mill stand and a rolled stock e.g. a metal plate or a strip in order to control the profile and flatness of the metal plate or strip. A special design to allow safe roll bending even at large roll gauges is presented. The new design allows safe operation even at large roll gauges and high side loads.

摘要： A feeder is provided for a punch. The feeder includes a feeding unit, a bending unit and a transferring unit. The feeding unit feeds a roll of a metal strip that includes a leading edge. The bending unit includes a plate for bending the metal strip, a sensor for generating at least one signal on detecting the arrival of the leading edge of the metal strip at the plate and a controller for actuating the plate on receiving the signal. The transferring unit transfers the metal strip to another unit of the punch.

摘要： In order to manufacture a pipe having a plurality of flow channels, by minimizing die jigs and steps, and thus to permit facilitation of manufacture, reduction of cost, and improvement of accuracy, the method of manufacturing a pipe comprises the steps of holding a sheet material at a center portion in the width direction thereof from both surfaces thereof by core members composing a split structure, folding both sides in the width direction of the sheet material in opposite directions and causing the thus folded both sides of the sheet material to follow the shapes of the outer surfaces of the core members, thereby forming a substantially an S-shaped cross-section. In a preferred embodiment, the method comprises the steps of providing outer dies, each of which has a concave surface substantially identical with the outer surface of one of the core members, and folds one of both ends of the sheet material toward the outer surface of the core member by the outer die while moving the outer die toward the core member.

摘要： Electro-unite tubes having different plate thicknesses or different diameters are breakdown-formed without changing the upper rolls and the lower rolls of the breakdown pass rolls each time. Each of breakdown pass rolls 12 includes an upper roll 12a having a convex curved surface and a lower roll 12b opposed to the upper roll 12a, the lower roll 12b being provided with a V-shaped concave portion 13. A gap is maintained between a metal band plate 11 and the deepest portion D in the concave portion 13, and the metal band plate 11 is in local contact with the lower roll 12b. The upper roll 12a can be moved up and down, and the distance between the end of the curved surface of the upper roll 12a and the deepest portion D in the concave portion 13 is adjusted depending upon the plate thickness and the diameter of the electro-unite tube to determine the curvature (R.sub.1 or R.sub.2) for forming the metal band plate 11.

摘要： Bending preshaped sheet metal pieces that have a web and side flanges, by stretching on one side, and compressing on the other side, by utilizing opposed rollers. They can be, and are, selectively bent into cylinder shapes or cone shapes. The bending steps produce folds in the extended edges of the flanges, of circular cross sectional shape, and in one form, are of large dimensions on one side and of small dimensions on the other side, and adjacent pieces are interconnected by placing the large fold of one piece over and encompassing the small fold of the other piece, to form lids of great area.

摘要： A sheet-metal blank (10) can be moved through between first and second bending rolls (24, 25). Disposed behind the bending rolls (24, 25) in its direction of movement (12) is a deflecting member (28) by which the sheet-metal blank (10) can be deflected away from the first bending roll (24) and round the second bending roll (25) out of its original direction of movement (12). In order to catch the edge of the sheet-metal blank (10) which was leading in the original direction of movement (12), a catch ledge (29) is disposed at the side of the second bending roll (25) remote from the first bending roll (24) and at least substantially in the common plane of the axes of the two bending rolls (24, 25). The catch ledge (29) is a component of a guide rail (30) on which the rounded sheet-metal blank (10) is guided with its longitudinal edges lying close beside one another during a further axial movement. The guide rail (30) extends at least substantially over the whole length of the two bending rolls (24, 25) and is arranged in such a manner that it is encircled by the sheet-metal blank (10) during the bending of the blank.
