    The invention relates to equipment for the manufacture of continuous pipes with a longitudinal weld of tape laminates with a metallic inner layer and an outer layer of polymeric material by reducing their edges and welding to form a longitudinal weld.
    The aim of the invention is to improve the quality of the weld,
    FIG. 1 shows the elements of the device for the continuous manufacture of pipes of laminated material, top view; in fig. 2 - part of the device with a partial section of the core, side view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 2 (on an enlarged scale) j in FIG. 5 - control with another profile.
    The device comprises a film roll consisting, for example, of an inner layer of metal foil and two detectable layers of plastic. The film is made of aluminum foil, covered with both sides with polyethylene. Laminated tape is coated on both sides to prevent its thickness from fluctuating or damaging the edges, which can reduce the quality of the weld. Thereafter, the tape is fed through the introduction funnel into the forming head 1 to form pipe 2 (Figs 1 and 2) with edges 3 overlapping each other (Figs 3 and 4).
    The molding head 1 consists of a profile sleeve 4 and a core core 5, the profile core 5 consists of any heat-conducting material, such as steel, Core 5 has channels 6 (FIG. 3) for passing a cooling medium, such as water. At the output end of the profile sleeve 4 above the overlap area of the edges 3 of the film tape is disposed parallel to the axis of the core 5 and across it is quadrangular, extending from the axis of the core 5, cooled by the high-frequency HF coil 7 for welding edges 3. Through this coil 7, a high density inductive field is provided. The coil 7 has a removable plate 8 made of heat-conducting current-insulating material of high hardness and with a low coefficient of friction. Plate 8 is adjacent to the overlapping zone
    The pipe 2 is formed from the profile sleeve 4 in such a way that this zone is securely guided and held. The pipe 2 coming out of the professional coupling 4 is covered on both sides by endless transport belts 9 tensioned on the drive and driven roller 10.
    At a distance from the coil 7 and in the overlapping zone of the edges 3, there is a pair of rollers consisting of one acting on the weld zone on the outside of the outer roll 11 and acting on the inside of the tilt wheel 12,
    The outer roller 11 is cooled and driven and provided with a pressure control device. The internal turnout 12 is installed in the cooled core 5, due to
    what is being cooled. The rolls 11 and 12 can be either flat or profiled, depending on the shape of the weld.
    The outer roller 11 of FIG. 4 is cylindrical, and the control valves 12 have a trapezoid notch 13 (see FIG. 4), the control valves 12 in FIG. 5 has a wedge-shaped notch 14. The rolls profile 11 and 12 determine the shape of the formed weld. By roller pair 11 and 12, contact is ensured along a straight line and, therefore, the degree of deformation is optimal. The core 5 from its short-circuit output of the profile muff. 4 and to its free end in the upper part has an axial groove 15 with a width greater than the width of the overlapping zone.
    From the beginning of the groove 15 in the exit zone of the profile-pin coupling 4, the full closed shape of the core 5 is provided with a removable insert 16. This insert 16 consists of a material with the same properties as the plate 8 of the high-frequency coil 7, In the output zone of the coil 7 due to the absence of the insert 16 a ledge is formed, i.e., the seam zone can no longer adhere to the core 5 and the danger
    sticking ,, This ledge MUST lie immediately after the point of gluing, in the direction of the scientific research institute there is no longer.
    The device works as follows
    The pipe 2 leaving the profile sleeve 4 is enclosed on the sides with transport belts 9, is guided and held from above by a plate
    8 of the coil 7 and below with a core core 5. In the high-frequency coil 7, a high-density inductive field is formed, which excites and heats the metal layer in the film. This heating spreads in the plastic layers between the metal foil in the overlapping zone faster than in the outer layers that come into contact with the detected elements: on one side with the plate 8 and on the other with the insert 16 of the core 5. In the inner zone due to the size When these plastics are bonded, these layers are bonded, and a bonding point is reached here. With the same power of the high-frequency coil 7, this gluing point for different film materials is reached at different times. Immediately after the gluing point has been reached, the maintenance of the zone; the seam with the insert 16 is stopped. retention is not necessary, since, on the one hand, there are no stresses in the heated and softened film that could lead to its deformation, and, on the other hand, the preset shape is retained due to gluing. Due to the fact that the core 5 does not have a closed loop, friction is also reduced. Upon the further movement of the pipe 2, the glued overlapping zone falls between the cooled rolls 11 and 12, where the seam acquires the final shape and at the same time is securely sealed. Due to the fact that the rolls 11 and 12 are cooled, the seam gets a rigid shape and the pipe 2 becomes so rigid that further direction is not required by the core 5.
    Forming the seam with rollers 11 and 12 should occur when the heat obtained in the film has sufficiently heated the plastic material of the outer layers. This point is defined as the ideal forming point. Shaft 22287804
    kami and may vary by changing the pressure of the rolls.
    The distance from the gluing point to the forming point of the rollers varies
    5 depending on the property of the film tape and the speed of the tube through the device. As a result, adjustment of this distance is required. For this purpose, the coil 7 is located with the possibility of movement in the direction of the pipe movement. In addition, the possible movement of the rolls. In order to take into account the distance from the coil 7 to the profile sleeve 4, more than 5 lengths are provided on the plate §, which covers the intermediate space.
    In accordance with the displacement of the gluing point, the length of the insert 16 should also be adjusted.
    20 energy is consumed, the easier it is to set the gluing point and the smaller the distance from the gluing point to the ideal roll forming point. The rate of distribution of the heat obtained in plastic layers can be provided by thermocouples. Depending on the selected speed, you can easily set the distance between the gluing points and the point
    , jQ roll forming and from coil 7 to roller pair 11 and 12. The drives of the transport belts 9 and the drive roll 11 are synchronous. The pipe 2 is heated only in the weld zone and only from the inside, and is cooled from the outside by the core core 5. and coil 7. The core 5 can be made of metal, for example steel. Due to the fact that the core is short, there is no need for additional supports. Due to the transverse movement of the high-frequency coil 7, the center of concentration of the inductive field is controlled by the width of the overlapping edges.
    The invention makes it possible to obtain longitudinal welded pipes from a laminate of good quality.
