    A method of and device for producing multi-layer pipes by helically winding a plurality of bands loosely arranged one above the other, which are individually withdrawn from a supply, straightened out, trimmed, and in the form of a band loop are conveyed to the forming station at the respective angle of lead-in corresponding to the respective pipe diameter, whereupon the layers are together welded to form a pipe strand which is subsequently cut into individual pipes. All bands are supplied and advanced independently of the irregularities of the respective longitudinal band edge shape in steadily straight lead-in directions, and all band edges are machined together to a possible maximum width in coordination with each other whereupon the bands are driven together while the welding gap is controlled in conformity with their band edge shape merely by pivoting the pipe.

    专利说明:

    Htox spiral-seam pipes from individual tapes, in which each of the tapes is unwound, right, they process longitudinal edges, combine tapes, feed them at an angle of molding into a forging unit, mold and weld the pipe, and then cut it to lengths before processing the longitudinal edges determine their relative position to one relative to the other, the amount of displacement is converted into a control signal for processing, the edges of all belts are processed simultaneously, and each side of the belt is processed independently of the other side on the maximum possible width of the belt, and the combination of all the belts and their joint movement is carried out in the molding unit. Such a method is carried out by an apparatus comprising a roll outcall, a straightening machine, a guide device, an edge processing device, a roll forming unit, a welding device, and a scissors for cutting pipes to lengths, the guide device being made in the form of drive lines. clamping rollers, the device for working the edges is made in the form of a movable slide with separate sets of cylindrical and profile cutters fixed on them, the pressure rollers and sets of cutters are made stepwise, at least one of the forming roll assembly is formed as a universal joint and va la fortified thereon with possibility of stepless changes its angular position adjusting thrust rings. FIG. 1 shows a device for carrying out the method, side view; in fig. 2 - molding. Node and exit frame, plan view; in fig. 3 — tack joint of a spiral seam of a three-layer pipe; in fig. tape edge processing with a tape direction system; in fig. 5 is a section A-A in FIG. ; in fig. 6 is a section through FIG. in fig. 7 - Raz cut BB in FIG. / +, with hydraulic system; in fig. 8 - section G-Y in FIG. l in fig. 9, upper roll of the forming unit, plan view; in fig. 10 - view along arrow D in fig. 9 (adjusting thrust rings izob,:, "are turned in a vertical position to the axis of the shaft); in fig. 11 - view along arrow fc. in fig. 10, incision; in fig. 12 - the same, when turning the shaft through 90®. The device comprises an accumulation table 1, a decoiler 2 rolls, a butt welding machine 3, a straightening machine, a device 5 for cutting longitudinal edges, a roll forming unit 6, a welding device 7 and scissors 8 for cutting pipes to lengths. The guide device 9 is made in the form of driving guide rollers 10 and clamping rollers 11. Edge processing device 12 is made in movable slide 13 with separate sets fixed on them and 15 cylindrical cutters and a set of 16 profile cutters, while clamping rollers and sets of cutters performed stepwise. The molding unit is made in the form of three rolls fixed in the casing 17. At least one of the rolls is made in the form of a shaft 18 and cardanally fixed on it with the possibility of infinitely variable angular position of the mounting thrust rings 19. The shaft 18 is mounted in a housing on bearings 20 and 21. On the shaft 18, through two diametrically located rotary axles 22, intermediate rings 23 are installed, on the outer perimeter of which they are arranged at an angle of 90 °, to the axles 22 of the axles 2. There are for the infinitely adjustable adjustment rings 13 Connecting rods 25-27 connected to the rings by means of segments 28 placed in the nasax rings 19; The method is as follows. Tapes 29-31. forming, respectively, spun, middle and inner layers of the pipe, simultaneously unwind, peel, weld transverse seams, right, they are rimmed and they are guided through the roller tables into the looper 35. After that, the tapes with the help of driving guide rollers 10 sent to an edge processing device. The required gradation of the diameters of the sets is determined by the difference in angles between the directions of entry of the inner and middle or middle and outer tapes.
    The diameter of the set and 15 mills is chosen so that the maximum expected depth of cut on both sets of mills is distributed approximately evenly. At the same time, due to the control, each blade of the set of 15 mills is in operation, but only the minimum total chip removal follows respectively.
    The profiles and gradations of the diameters of a set of 16 profile mills are determined by the selected weld geometry for butt welding.
    For the straight direction of the belts with given entry directions V / V, VQ, Vj, which are different from each other due to the same for all layers of helix pipes but different diameters, the clamping rollers 11 and located in pairs in front of a device for processing edges on both sides of each tape guide rollers 10.,
    The clamping rollers are stepwise (according to the difference in the angles oL between the directions of entry of the inner and middle or middle and outer tape) in diameter and by means of the hydraulic system 36 are pressed against the edges of the three tapes that are milled according to each other on both sides with an adjustable constant force.
    The guide rollers by means of the drive 37 in combination with the control 38 and the follower unit 39 are mounted respectively along a longitudinal passage of the edges of the belts.
    The control 38 consists mainly of a sensor "About preset position, sensor 41 of the actual position, amplifier 2 of the control system and power amplifier.
    Thanks to this guiding system, the individual tapes are guided Bcei and in a straight line, according to the established different entry directions.
    After milling, the ribbons are fed into the molding unit, are aligned in the roll installation area, molded into the tube billet and welded into the pipe, and then the pipe is cut to length.
