    The invention relates to polymer engineering and can be used in the manufacture of pipes from thermoplastic synthetic materials.
    A device for the manufacture of plastic pipes, in which an annular head is attached to a kneading, in the form of a screw extruder, has a ring-shaped slit in the head, which acts as a nozzle and is limited by a mandrel, fixedly mounted in the body of the head, and an annular mouthpiece with a gap ossive outer end of the mandrel, while the mouthpiece with a radial clearance is mounted in a sleeve connected to the body of the head, and can be installed with several radially located s
    in the hub of the screws in order to obtain a uniform nozzle gap.
    However, in this device, fine adjustment of the gap is difficult and takes
    a lot of time, as before tightening one set screw, it is necessary to at least loosen the other set screw. In addition, for such adjustment always
    Special tool needed.
    The closest to the invention to the technical essence and the achieved result is a device for the manufacture of pipes from thermoplastic synthetic materials, comprising a head housing with an annular nozzle slit formed between fixedly attached to the plasticizing unit
    the mandrel and tubular mouthpiece, covering the outer end of the mandrel with a gap, the mouthpiece mounted on the front side of the body by means of a ball bearing and fixed to the body with spring-loaded screws t23. A disadvantage of the known device is that, due to the large number of screws, precise adjustment of the annular gap is practically not achievable. As a result, manufactured products are of poor quality due to the significant thickness variation of the walls. The purpose of the invention is to improve the quality of products by providing precise adjustment of the gold ring annular gap. This goal is achieved by the fact that a device for the manufacture of pipes from thermoplastic synthetic materials, comprising a head body attached to the plasticization unit with an annular nozzle slot formed between a mandrel fixedly mounted in the case and a tubular mouthpiece, covering the outer end portion of the mandrel with a gap, moreover, the mouthpiece is mounted from the front side on the body by means of a spherical support and fixed on the body with spring-loaded screws, provided with at least two ring-shaped kosou guns placed outside the ball joint between the body and the mouthpiece and pivotally mounted relative to each other. In addition, between the case and the mund, two pairs of ring washers are assembled, formed from each of the two obliquely angled washers. At least two oblique washers are equipped with at least one adjustment knob. Oblique washers are mounted in an annular groove, which is made in the mouthpiece, and on the end surface of the case, an annular ledge located in the area of the annular groove is made. The device is equipped with at least three evenly distributed around the circumference of the head housing and mounted with the ability to move in the axial direction of the supporting elements. The supporting elements are located in the zone of oblique washers. 8 Supporting elements are made in the form of a first hydraulic or pneumatic system. According to another embodiment, the device is provided with at least three uniformly distributed around the circumference of the housing and installed outside the ball bearing with the possibility of movement in the axial direction of the supporting elements. Such a design of the device allows to achieve high quality products, to ensure precise adjustment and adjustment of the annular slot of the head, and thus to ensure a uniform thickness of the walls of the forming pipe. This does not require loosening the adjustment screws or tightening them. This is ensured by the fact that when the oblique washers rotate relative to each other or the axial movement of the supporting elements, the mouthpiece which is held on the head body with the preliminary tension of the screw spring only slightly fluctuates when the obliquely rotating axes or the axial movement of the supporting elements rotate. In the shortest possible time, simple and precise adjustment of the nozzle gap is achieved. With simultaneous use of oblique washers and support elements, the latter in this case serve only to adjust oblique washers, i.e. dp is setting their zero position. FIG. 1 shows an annular head with oblique adjustment shields; FIG. 2 - two oblique washers complementing each other, cross section; FIG. 3 ring head with oblique) pipes and support elements for adjusting the slit, the cut, on the same, is optional. The apparatus for the manufacture of pipes from plastics comprises a casing 1 of an annular blow-out head 2, which is connected to the plasticization unit, which is made in the form of a screw extruder (not shown). In case 1, heads 2, which are known by way of, are fixed in the center by a mandrel 3, which protrudes beyond the limits of case 1. In this zone, mandrel 3 is surrounded with a certain gap by a tubular munaptuse 4 so that a annular nozzle 5 is formed between mandrel 3 and mouthpiece 4. the front side is supported through the ball bearing 6 on the body 1 of the head 2 and has several holes 7 for spring-loaded screws 8, which are equipped with cup springs 9 located under the head 10; screws 8. Mouthpiece 4 has in its plane, facing the body 1 of the head 2, an annular groove 11, in which four ring-shaped oblique washers 12 are inserted (Fig. 1 and 3). These oblique washers are arranged as shown in FIG. 2, and, respectively, two oblique washers 12 complement each other up to a pair of annular washers 13. In the area of the annular groove 11 (Fig. 1), the front surface of the body 1 has an annular protrusion 14, which under certain conditions can be discharged. On this protrusion 14, the head 2 of the oblique washer 12 is turned around to the body 1. Oblique necks 12 are equipped with at least one regulating knob 15, by means of which they can turn relative to each other. I The annular protrusion 14 is replaced by three axial directions of the supporting element 16 being moved ri and ri (Fig. 3), respectively. The supporting elements 16 are evenly spaced along the plane of oblique washers 12 and are made in the form of pistons that are located in cylindrical holes 17 bored in housing 1. In this case, supporting elements 16 move in holes 17 and have holes against the walls of the cams. . The holes 17 are made to a predetermined size longer than the supporting elements 16, so that in the hole 17, there is always a free space 18, limited by the corresponding supporting element 16. Each space 18 is connected through the channel 19. to the hydraulic or pneumatic system, through The working medium can be introduced into the space. According to another variant, no oblique washers are provided in the device (Fig. 4), and the supporting elements 16 directly act on the mouthpiece 4. In such a design 8, the zero position is set, the adjustment and oscillation of the mouthpiece 4, respectively, governing the parameters of the nozzle slit, takes place exclusively through the support elements 16. The device works as follows. The melt of plastic mass from the plasticization unit enters the head 2 and through the annular gap 5 comes out. When rotating obliquely 12, mouthpiece 4 rotates slightly. Due to this, it becomes possible to adjust the annular gap 5 by centering the mouthpiece 4 with respect to the mandrel 3. Since the movement of the mouthpiece 4 is less than the spring travel 9, the adjustment is carried out without tightening or loosening the screws 8. In case the device has only supporting elements 16, the rotation of the mouthpiece 4 is carried out by supplying the working medium in space 18. The working medium is supplied independently to each individual space 18 according to commands from an electronic control system (not shown). When the working medium is supplied to the space 18, an axial movement of the support element 16 takes place, which, turning the mouthpiece 4 on the joint support 6, aligns it with the mandrel 3. In the case of the arrangement of the device (FIG. 3) with oblique washers 12 and support elements 16 when When the working medium is supplied to the space 18, axial movement of the supporting elements 16 takes place. In this case, the supporting elements rotate the mouthpiece 4 on the ball bearing 6 and adjust the position of the oblique washers 12 to the zero position. Then, from this zero position, rotating with the handle 15, oblique washers 12, rotate the mouthpiece 4, adjusting the annular gap 5 by centering the nozzle relative to the mandrel 3. Thus, precise adjustment of the annular gap of the nozzle is achieved, ensuring uniform thickness of the product walls. 1c ie 15 P 15 16 P 5 Figure 5 2 P 19 18 IS
