    The invention relates to welding, in particular, to devices for connecting a tubular portion of a tube made of a multilayer film comprising plastic layers and a metal protective layer, to the head part of the tube by means of high-frequency induction welding.
    The closest in technical essence and the achieved result to the invention is a device for induction welding of tubular parts from a multilayered film with a mezzanine layer Mp containing a molding mat, with an axial orifice and a multi-turn induction calligraphy associated with a cooling source f.
    The drawbacks of the known device are that the molding matrix is made of ceramic material, which is a relatively poor conductor of heat, therefore, heat removal from the welding zone is not possible in a short time and the number of welding joints produced per unit time is non-znier. In addition, ceramics with time it heats up and leads to a change in the surface of the outer sidewalls of the head of the tube, e, the plastic loses shine and becomes dull, which negatively reflects on the appearance of the tube. In this case, for ceramic materials there is always the danger of infrared damage when exerting the pressure required for welding.
    In the device, it is possible to arrange the source of inductance in the mandrel and screen the floor in the tubular part of the tube, since then it is possible to manufacture the molding matrix from metal in order to shorten the cooling time after the welding process. However, this solution has a number of drawbacks, since the coil is required for cooling; and shielding devices must be placed in a limited mandrel, which must be movable in several directions, which leads to problems in cooling and in the supply of current, with the atom being able to use only the Katugzhi edge field.
    The aim of the invention is to increase the welding speed.
    This goal is achieved by the fact that in the device for induction welding of tubular parts made of a multilayer film with a metal layer containing a molding matrix with an axial bore and a multi-turn induction coil associated with a cooling source, the molding matrix is made of colored etal with a radial sponge and is provided with a sleeve of the non-electrically conductive material, and the induction coil is electrically connected to a molding matrix of one turn length on either side of the slot.
     In addition, the slot is filled with non-conductive material.
    The outer surface of the molding die is conical.
    Channels for cooling media are made in the matrix.
    The guide sleeve is made with a conical inlet.
    The molding matrix is provided with an annular insulating element.
    The molding matrix is made of two coaxially arranged and connected with each other parts, moreover, the radial head is placed in one of the parts of the matrix, and the guide sleeve in the other. The induction coil is placed in a part of the matrix with a radial slot, which is mounted movably relative to its other part. By performing a molding matrix of non-ferrous metal with a radial slot and with a guide sleeve of non-conductive material and an electrical connection of the induction coil with the molding matrix for one turn; and on both sides of the slot, the metal matrix does not act as the magnetic field shielding element a as a concentrator, so that the total magnetic flow can pass only through the axial hole and due to the fact that the metal is a good conductor of heat, in the welding zone can t be achieved optimal heat dissipation. In addition, in the case of a metal marina, the pressure necessary for a good connection of the parts of the tube can be applied without fear of its destruction. Filling the slot with a non-electrical HciM filler eliminates the danger of getting the softened plastic material into the slot and prevents the surface of the side portions of the tube head from warping. Performing the matrix of two parts allows reducing production costs and adapting it to different forms of tubular parts, and the guide sleeve with a conical inlet provides easy insertion and precise centering of the mandrel with the tubular part and the tube head relative to the coil. FIG. 1 shows an example of a device with an insulating element in FIG. 2 is the same, a view of a downward view of FIG. 3 shows an example of a device with moving parts of a matrix that are movable on each other of the carrier. A device for induction welding of tubular parts made of a multilayer film with a metal layer contains a molding matrix, made of coaxially arranged and connected with each other parts - upper 1 and lower 2 from non-ferrous metal. The mold matrix has a through axial hole 3. The outer surface 4 of the molding matrix, in particular its upper part, is made conical, on which a multi-turn induction coil 5 is spirally shaped. The high-frequency induction coil is impregnated on the matrix by one external coil 6 and due to this electrically connected zana with her. Other coils are isolated with respect to the fort of the matrix. The upper part 1 of the molding matrix has on its bottom side 7 a circular recess 8, into which the protrusion 9 of the lower part 2 of the molding matrix enters, the upper upper 1 and the lower 2 parts of the matrix around the axial hole 3 have an annular insulating element 10. The parts 1 and 2 of the molding matrix detachably connected to each other by means of a screw connection 11 and clamping between the assembly an insulating element 10, which, if necessary, can be easily replaced. The recess 8 and the protrusion 9 serve to center the parts 1 and 2 of the molding matrix during their assembly, and their height corresponds to the thickness of the insulating element 10, t, e, even with its greatest thickness, the protrusion 9 approaches the recess 8. The molding matrix has on one side radial narrow slot 12 filled with electrically non-conductive filler 13. Attached to the forming matrix, i.e. the electrically connected winding 6 begins on one side of the slot 12 and ends on its other side, i.e. slot 12 is not electrically shunted. The induction coil 5 is made in the form of a hollow conductor and is connected to a cooling source (not shown), the molding matrix has a system of channels 14 for the cooling medium, and the channels 14 can be located in the upper and lower portions of the matrix. A guide sleeve 15 of a non-conducting current material is fixed on the lower part 2 of the molding matrix. At the free end, the guide sleeve is made with a conical inlet to facilitate insertion of the carrier head and the tubular part of the article. the mandrel is not (shown) Heater tube 15 is made and positioned so that it covers the mandrel with the tubular part and is centered relative to the induction coil 5, the axial hole 3 is expanded in the upper part in the shape of the outer sides of the head part of the tube at least in the joint area, head with tubular. This expansion can be performed only in the lower part 2 or in the upper part 1, and, if necessary, an insulating element 10 between them, if necessary, reflects the shape of the go-. product. In the example of the Device shown in FIG. 3, the system of cooling channels 14 is located in the lower part 2 of the molding matrix. The shape of the lateral sides of the head of the tube, the shape of the expansion of the axial bore 3, is contained only in the lower part 2 of the matrix. The induction coil 5 is located on a metal disc 16 with a spigot. The upper part 1 of the mold, the die is set movably in the axial direction relative to the lower part 2, the coil b of the induction coil and the ring holding it are arranged in such a way that the die slot 12 of the matrix is not electrically shunted. The matrix is preferably made of brass, as it has great strength, than copper. However, all non-ferrous metals can be used. A two-component adhesive made from an artificial resin based on an epoxy resin can be used as an insulating mass, for example, araldite. The insulating element 10 can be made of alumina or ceramic material, for example glass with inorganic fillers. Equal sleeves can be made of a material of low hardness, for example, plastic, in particular, Teflon. The device works as follows. The tubular part of the tube, having a metallic safety layer, is drawn onto the sides of the heads. No metal part. Due to the magnetic field excited by the induction coil, the metal layer in the overlapping zone is heated and softens the adjacent plastic layers. Thanks

    Us.3 The pressure exerted by the matrix is firmly connected. If the head of the tube has a metal protection layer, then in the tube, due to the induction field, a short circuit current is created, which also develops heat and magnetic reaction, counteracting this head field. The intensity of the currents induced in the metal field of the head of the tube is determined by the insulating element 10, which separates a part of the field. The side field penetrates the directly insulating element 10 and concentrates in the overlapping area of the head and tubular parts of the product, where targeted heating is provided. The intensity of the induced currents can vary depending on the thickness of the insulating element 10. The current flowing through the induction coil leads to the formation of a magnetic field, which affects the forming matrix in such a way that the entire magnetic flux flows through the hole 3, the concentration of the field is thus determined by the shape of the hole 3 , in particular its diameter and depth. By choosing the diameter of the hole 3 of the forming matrix and the thickness of the insulating element 10, the energy distribution during welding can be achieved. The proposed device provides high-quality and fast welding of the tubular part of the tube with the head.
