    专利说明:

    The invention relates to the processing of extruded rubber compounds for the manufacture of tire treads.
    The purpose of the invention is to increase the reliability of the head at high mass pressures.
    Fig. 1 shows an installation for making protectors in a closed position, a longitudinal section; in fig. 2 - the same, in the open position; Fig. 3 shows an extrusion head, a perspective view; in fig. 4 - blocking system: with a common center of rotation and a plot of forces.
    The extrusion head contains a stationary middle part 1, top 2 and bottom 3 parts connected to the hydraulic cylinders 4 and 5 of their rotation and mounted to form at least two flow channels 6 and 7 located above the other with the fixed middle part 1 The head has inserts 8 and 9 and locking elements, embodied in the form of cylinders 10 and 11, mounted on the rods of the hydraulic cylinders 12 and 13 for their transverse to the working direction of the extension head on both sides of the head to the outside of the upper 2

    ABOUT
    and the lower 3 parts of n in the side of the head. Extruders 14-17, one above the other, are attached to the head of the flange. The head is equipped with a blocking system at dust pressures for the top 2 and 3 shaney parts of the head, located on the side of the holo and vyushnepna in the form of hydraulic locking means for the top 2 and lower 3 parts containing trap cheeks 18 and 19 with recesses 20 and 21 for entering the locking elements 10 and 11 and the intermediate parts 22 and 23 are triangular in shape, pivotally connected by the hinges 24 and 25 to the traction cheeks 18 and 19 and to the hydraulic rings 26 and 27 and displacements, the intermediate parts 22 and 23 of the hydraulic blocks of the Ruyngr means upper 2 and lower 3 pieces of go Dexters have an obgdie, the center of rotations in the form of a hinge 28 located at the intersection of the draperic bushes 29 and 30 to the inner surfaces 31 and 32 of the upper 2 and lower 3 head portions, corresponding to the directions of the resulting ground mass pressure, located on the middle part 1.
    The principle of operation of the head is in C1
    From FIG. 2, the open position of the extrusion head, the upper part of the holoper 2 is moved downward by means of the hydraulic cylinder 4 to the one shown in FIG. 1 position. (The lash part 3 of the head is moved upwards by means of the hydraulic cylinder 5.
    The catfish are bent and even pressed together with the force of a seal to the middle part 1 of part 2 and 3 of the head are shown in a perspective view in FIG. 3
    Then, parts of the head are sealed from high pressures by means of locking elements and a locking system.
    By means of the hydraulic cylinder 12, the cylindrical locking element 10 extends laterally from the upper part 2 of the head and enters a circular recess 20 in the pulling cheek 18. Then the hydraulic cylinder 1 double acting 26 pulls a force on the triangular intermediate piece 22, which with increasing magnification transfers it to t beef cheek 18.

    This force moves the pulling cheek 18 in the direction of the middle part 1 of the head, with the result that the upper part 2 of the head is pressed against the middle part 1 of the head with greater force. As a result of placing the center of rotation 28 at the intersection point of the resultant lines USIL-1B of the mass back pressure, a balanced structure is created that perceives very large forces (up to 300 bar) without deforming the parts. In the same way, locking of the bottom 3 of the head is carried out. FIG. 3 for clarity, blocking is shown only on one side of parts 2 and 3 of the head,
    The extruders 14-17 are designed to plasticize, homogenize and pour various rubber compounds to form a tread 33 using a head.
    If it is necessary to change the inserts 8 and 9 when changing the mixture, for example, to get another profile and to clean, the head is softened with the help of hydraulic cylinders 4 and 5 and the inserts 8 and 9 are removed. After that, you can remove the screws from the extruders 14-16.
     due to the presence of cylindrical, transverse guides transverse to the working direction of the head from the rotary parts 2 and 3 of the head of the locking elements 10 and 11, which enter the recesses of 20 and 21 t cheeks 18 and 19 of the hydraulic block X means, and due to the creation of a large tractive force of the hydraulic cylinder 26 and 27 it is possible to create smoothly increasing maximum compaction pressures.
    The design of the blocking means is significantly T1forced due to the ONE of the common center of rotation of the two blocking means, i.e. means for locking the upper part and means for locking the lower part of the head. On the other hand, the STORO1SH saves costs and space for the second point of attachment of the blocking system or for the hydraulic cylinder, therefore the visibility of the blocking system is significantly improved.
    It is especially effective to place a common center of rotation for both blocking means for the upper 2 and lower 3 parts of the head at the point of intersection of the resultant forces.

    mass pressures emanating from the inner surface of the upper 2 and the inner surface of the lower 3 part of the head, since the arrangement of the center of rotation with the balanced forces is achieved. One who perceives high closing forces ;; the center of rotation is thus at the point of intersection of the resulting back pressure forces from the internal surfaces of the head, as a result of which a uniform distribution of stresses from the forces in the head is achieved.
    The resulting direction of effort, i.e. The direction of the back pressure emanating from the flat inner surface, for example, the upper part 2 of the head, forms a right angle with the inner surface of the head part. At the point of intersection of both directions of forces from the inner surface of the upper 2 and lower 3 parts of the head, the center of rotation and the point of attachment of the blocking means are located, as a result of which a statically balanced point of view of maximum forces is found for almost all rubber compounds being processed.
