Abstract
888,086. Bending sheets to tubular form. COMPAGNIE DE PONT-A-MOUSSON. May 3, 1960 [May 6, 1959], No. 15504/60. Class 83 (4). A machine for bending sheets to tubular form comprises a single anvil suspended by a flat plate from a plurality of frames, bending device, and hydraulic actuating means therefor, being carried in front of each frame to co-operate with the anvil to bend a sheet. A sheet t is positioned on guides 17 against a pivoted stop 36 and its rear end is contacted by abutments 18 on a rack 19. A plurality of hydraulic rams V1 are then actuated to raise a series of bending members 13a, 13b, adjustable towards each other, to engage the end part of the sheet t and bend it against an anvil 7 carried by a plate 4 supported by a plurality of frames 2, each frame being associated with a ram V1, the stop 36 being raised by a bending member 13b. The rams V1 are then lowered and a ram V2 is actuated to move the rack 19 and thus the sheet t towards the anvil 7. The next section of the sheet t is then bent and the successive feeding and bending is carried on until a half-tube has been formed. The rack 19 is then withdrawn by an electric motor and the bent sheet pulled out of the machine and then fed in again, the unbent half first. The sheet in tubular form may then be withdrawn and welded. In one arrangement, Fig. 13, embodying two bending machines M1 and M2, a sheet t<SP>1</SP> is fed by a conveyer T1 to the feed means B1 of the machine M1 wherein a half-tube t2 is formed. This is withdrawn by an extractor U1 and fed to the machine M2 which completes the tube T. This is extracted by means U2 and transferred to one of two conveyers Y which carries it to means Z to weld the longitudinal edges. The sheets may be bent up at the edges before being presented to the bending machines.
