    摘要: A device for helical coiling of pressure vessel shells comprises a frame (4) traversable along the axis of a pressure vessel shell (1). The bottom portion of the frame (4) mounts a pressing mechanism 5 vertically traversable along the radius of the pressure vessel shell. A mechanism (6) for tensioning the steel strip being coiled is located before the pressing mechanism (5) as along the direction of run of the steel strip (13) from a coil (9) towards the pressure vessel shell (1). The pressing mechanism (5) has a beam (23) secured on the frame (4) and provided with forks (21) and rollers (20), both facing the pressure vessel shell. Each of the rollers (20) is mounted in its own fork (21) and spaced apart from another roller a distance 10 to 50 times the thickness of the steel strip (13) being coiled, and is situated on the generatrix of the pressure vessel shell (1) across the entire width of the steel strip (13) being coiled. The steel strip tensioning mechanism (6) is made as a group of rolls (16) of which the extreme two rolls (18, 19), as in the direction of run of the steel strip, have a convex and a concave camber, respectively, facing the surface of the steel strip (13). The radius of curvature of said cambered roll surfaces is determined by the thickness and mechanical characteristics of the steel strip (13) being coiled and by the amount of plastic deformation required to compensate for the marginal effect tending the edges of the steel strip (13) to flange outwards when the strip is being coiled onto the pressure vessel shell (1) past the pressing mechanism (5).

    摘要: A mill for manufacturing bodies of multilayer high-pressure vessels comprises rotators (3) of the body (1) of the high-pressure vessel, which have the butt end portions of the body (1) of the high-pressure vessel secured therein. The body (1) of the high-pressure vessel is surrounded by a portal (5) capable of moving along the body (1) of the vessel. An upper platform (8) of the portal (5) carries a technological line (15) for preparation of the steel strip for its winding onto a central pipe (16) of the body (1) of the vessel, the steel strip (2) being supplied from a coil (18). A crossbar (9) secured to uprights (10) of the portal (5) carries an arrangement (32) for tensioning the steel strip, which can move along the crossbar (9) and from which the steel strip (2) is supplied to the upper generatrix of the body (1) of the vessel in such a manner that a free loop ( 30) of the steel strip (2) allowing for a turn of the arrangement (32) for tensioning the steel strip in the horizontal plane is formed between the technological line (15) for preparation of the steel strip for its winding onto the central pipe (16) of the body (1) of the vessel and the arrangement (32) for tensioning the steel strip. The mill also comprises a fixture for welding the steel strip (2) to the end portions of the body (1) of the vessel and turns of the steel strip (2) to one another.
