    The device is intended for securing a thermoplastic cover (2) to a tubular construction element (1). The cover (2) is tightly fitted in the tubular construction element (1), which is provided with holes (8) in the region of cover (2). A peg (9) is hot-driven in the material of cover (2) through each hole (8). The diameter of the peg (9) is smaller than that of the hole (8) so that under the effect of the heated peg (9), the expelled material (12) may flow through the hole (8).

    2. Connection according to claim 1, characterized in that the pins are made with at least one annular groove on the lateral surface of one of the ends and are mounted with this end in the body of the crack.
    3. The connection according to claim 1, characterized in that the pins are made with a gradually decreasing diameter on the horses.
    4. A method for producing a permanent connection of a shaped cap of a thermoplastic material and a tubular part surrounding it with openings on the side surface by pressing the cores of heat-resistant material, preferably metal, with a diameter smaller than the diameter of the openings heated to the cap through the said openings of the tubular part softening temperature of the thermoplastic material, before the latter flows into the gap between the walls of the holes and the rods, characterized in that. in order to increase the load capacity, pins are used as rods, which, after being pressed into the thermoplastic material of the lid, are held until it hardens and forms a permanent connection.
    5. The method according to paragraphs. 2 and 4, characterized in that the crush is heated before installation in the tubular piece, and the pins are pressed into the heated crush body.
    The invention relates to machine parts and can be used to form a permanent connection of two parts, one of which is a shaped cap of a thermoplastic material, and the second one covering the cap of a tubular piece.
    A one-piece connection of a shaped cap of a thermoplastic material and a tubular part embracing it is known, comprising locking elements made in the form of hollow protrusions on the side surface of the cap placed in the through side openings of the tubular part made in the last interaction zone with the side surface of the cap 1.
    There is also known a method of obtaining a one-piece connection of a shaped cap of a thermoplastic material and a tubular part surrounding it with openings on the side surface by pressing a cap into the body of the core of heat-resistant material, preferably metal, with a diameter smaller than the diameter of the openings heated to softening temperature of thermoplastic material, before the latter flows into the gap between the walls of the holes and Cl 1 rods.
    However, all-in-one connection. obtained in this way does not provide sufficient load capacity, since the parts are interconnected only by means of a hollow protrusion of a thermoplastic material. In addition, this technical solution can only be used to form compounds that are not heated during operation. Otherwise, the thermoplastic material will soften under the action of heat and a misalignment may occur in the joint.
    The purpose of the invention is to increase the load capacity of the connection.
    The goal is achieved by the one-piece connection of a shaped pipe made of thermoplastic material and a tubular part encompassing it, containing fixing elements made in the form of hollow protrusions on the side surface of the cap, placed in the through side openings of the tubular part the surface of the bolt, the fixing elements are provided with pins of heat-resistant material, mainly of metal, made with a diameter smaller than the diameter of the holes in the tubing one part and mounted with one end cap body 3 and the other in the openings of the tubular part, while on the style krshka formed with a flange and yc tanovlena to cooperate with the bearing surface of the flange end of the tubular member. In addition, the pins are made with at least one annular groove on the side surface of one of the ends and are installed with this end in the body of the cover. The pins are made with gradually decreasing diameter at the ends. According to the method for producing a permanent joint of a shaped crack of thermoplastic material and a tubular body encompassing it with openings on the side surface by pressing the cores of heat-resistant material, predominantly metal, with a diameter smaller than the diameter of the openings heated to temperature through the said openings of the tubular part To grind a thermoplastic material, before the latter flows into the gap between the walls of the holes and rods, pins are used as rods; Do not press into the thermoplastic material of the lid until it hardens and forms a permanent joint. In addition, the lids are heated before installation into the tubular part, and the pins are pushed into the heated body of the KGN1KI. FIG. 1 shows a permanent connection of a shaped cap made of a thermo-plastic material and a tubular part embracing it in FIG. 2, node I in FIG. 1. The one-piece connection of the shaped cap 1 of thermoplastic material and the tubular part 2 surrounding it contains locking elements in the form of hollow projections 3 on the side surface of the cap, which are placed in through lateral openings of the x 4 of the tubular part 2 side of the lid, and the pieces you .5. The pins 5 are made of a heat-resistant material, predominantly of metal, with a diameter smaller than the diameter of the through side holes 4 in the tubular part, ...; And they are installed at one end in the hole and the other in the said holes. Shaped lid 1 is made with flange 6 and is installed with the possibility of interaction between the support surface 7 of the flange and the tubular part. In a preferred embodiment, the pins 5 are made with at least one annular groove 8 on the side surface of one of the ends and are mounted with the said end in the body of the shaft. In addition, the pins are made with a gradually decreasing diameter at the ends 9 and 10. A method for producing a permanent joint of a shaped cap of a thermoplastic material and the tubular part surrounding it with openings on the side surface is carried out as follows. Shaped lid 1 is preheated to a temperature that exceeds the operating temperature of the finished unit, and placed in the tubular part 2 until it stops with a flange 6 in the end of the tubular part. Then, the pin 5, heated to the softening temperature of the thermoplastic material, knocks, is pressed through the holes 4 of the tubular part into the body of the cap. The pins soften the thermoplastic material, which is extruded into the hole of the tubular part and fills the annular groove 8 on the side surface of the pin. The pins are held until the thermoplastic material of the lid hardens, resulting in a permanent connection. As a result of the fact that the shaped cap was preheated to a temperature exceeding the operating temperature of the unit, its dimensions decrease during cooling, and the flange 6 fits snugly to the end of the tubular part. The invention makes it possible to obtain a reliable one-piece connection of a shaped die of thermoplastic material and the tubular part surrounding it, which ensures an increase in the load capacity of the connection.
