    专利说明:

    The invention relates to the manufacture of automobile tires and is intended for their vulcanization.
    The purpose of the invention is to reduce the energy consumption of the vulcanizer by using air heated as a coolant directly in the vulcanizer.
    The drawing shows the proposed vulcanizer, the cut.
    The tire vulcanizer contains a mold 1.2 formed by the lower 3 and upper 4 half-molds. The upper mold 4 is annular and has an L-shaped radial cross section, due to the annular upper wall 5 with a central hole 6 and a cylindrical side wall 7 directed downward from the outer edge of the upper wall 5. There is a p on the periphery of the lower end of the side wall 7 For the outer wedge-shaped protrusions 8. According to the inner diameter of the annular wall 5 there is an annular groove 9 in which the upper side ring 10 enters with a collar 11 along the inner diameter in the form of a truncated cone.
    The center hole 12 of the side ring is coaxial with the hole 6 in the upper wall 5.
    The bottom half of the coupling 3 is made if the annular if in radial section has a L-shaped, due to the presence of an annular bottom wall 13 with a central hole 14, coaxially hole 6, and a cylindrical side wall 15 directed upwards from the outer edge of the bottom wall 13. At the upper end of the bottom half 3 there is an annular flange 16 which is included in the inner annular groove 17 of the benton lock 18 for connecting the half-molds 3 and +. At the upper edge of the lock 18, there are a series of notches 19 for the passage of the projections 8 into the annular groove 17.

    The height of the groove 17 is chosen such that when the lock 18 is turned relative to the half-molds, the latter are tightly closed. In the inner diameter of the wall 13 there is an annular groove 20 for mounting the lower side ring 21. On the inner surface of the side walls 7 and 15 there are profile inserts 22 for forming a pattern on the running part of the tire.
    In the closed position, the molds 3 and 4 form an annular forming cavity with a C-shaped radial section.
    The bottom wall 13 is connected to a support cup 23 coaxially with a hole 14. In the bottom of the cup 23 there are several through holes 24.
    The vulcanizer has a diaphragm assembly with an elastic diaphragm 25 and upper 26 and lower 27 disks for fastening its sides and a head 28 for supplying a heat transfer fluid.
    The head 28 is connected to the upper disk 26 and is provided with an elastic ring 29 placed in the cavity of the elastic diaphragm 25. The elastic ring 29 is fixed on the side surface of the head 28 between its openings for supply 30 and outlet 31 of the heat transfer medium. Holes 30 and 31 are evenly spaced around the perimeter of the head.
    The vulcanizer is equipped with a cylindrical crankcase 32, which is supported by the bottom of the cup 23. The crankcase 32 is located coaxially with the opening 6 and has a central opening 33 coaxial with the latter with a hub 34. The output shaft 35 of the electric motor 36 is mounted on the lower end of the crankcase 32. A shaft 37 is mounted in the crankcase cavity with a fan 37 for circulating a heat transfer medium. Valve 38 is fixed to the crankcase for supplying heat transfer fluid.
    The upper end 39 of the crankcase 35 is connected to the lower disk 27 of the diaphragm assembly to form a closed cavity with the elastic diaphragm 25. In the cavity of the crankcase 32, at its upper end 39, a heater 40 of the heat carrier is placed, having a plurality of through channels 41 and dividing the cavity of the crankcase 32 into the upper 42 and lower 43 chambers. The upper chamber 42 is connected with the cavity of the diaphragm 25 through the holes 30 of the head 28, and the lower chamber 4 43 is connected with the cavity of the diaphragm 25 through the holes 31 of the head 28.
    The means for controlling the diaphragm 25 is made in the form of a cylindrical sleeve 44 mounted concentrically to the crankcase 32 and is capable of axial movement relative to the latter. The cylindrical sleeve 44 is made with an inner diameter, a large diameter of the sides of the diaphragm 25, and an outer diameter smaller than the inner diameter of the tire blank 45.
    The cylindrical sleeve 44 is rigidly connected with the side ring 21 of the lower half-form 3. The annular groove 46 is located between the upper part of the sleeve 44 and the upper end 39 of the crankcase 32.
    The lower part of the sleeve 44 is disposed above the holes 24 of the bottom of the supporting sleeve 23.
    The lower chamber 43, in combination with the channels 41, the upper chamber 42, the openings 30, the elastic diaphragm cavity 25 and the openings 31, form a closed loop for the circulation of the gaseous heat transfer fluid supplied to the vulcanizer through the valve 38.
    Resistive electric heating elements 47 are mounted in the walls 5, 7, 13 and 15 of the half-form, which, like the heater 40 and the electric motor 39, are connected to a corresponding source of electrical current (not shown);
    To ensure proper sealing of the connector between half-molds 3 and 4, during the vulcanization process, the lower half-mold is assembled from two annular portions 48 and 49, the first of which is a cup-shaped holder and the second has an annular shape. The ring element 49 is installed in the casing 48 by means of an elastic compensation element 50. The latter can be made

    in the form of a ring of elastic material or a set of springs, or compressed gas.
    The vulcanizer works as follows.
    Before starting work, the upper half-form 4 is held in a position above the lower half-form by a special lift (not shown), and the shaft 44 is also held in an upper position by means of pushers (not shown) passing through the holes 24. Sleeve
    44 deforms the elastic diaphragm 25 and holds it and the elastic ring 25 in an upwardly bent position, in which the outer edge of the ring 29 protrudes upwardly over the upper disk 26 and is located inside a circle whose diameter is less than the inner diameter of the workpiece 45 loaded into the vulcanizer.
    Then the tire blank is loaded.
    45So that its lower side is disposed on the side ring 21 of the lower
    half molds. By lowering the guillotine 44, the tire blank 45 is placed in the lower mold half 3. At the same time, the elastic ring 25 returns to its original position. Then, through the valve 38, low-pressure compressed air is supplied, through which the diaphragm 25 is charged into the cavity of the tire blank 45.
    After that, the upper mold 4 is lowered until the side ring 10 interacts with the tire side 45 of the blank. The bayonet lock 18 is used to tightly connect half-molds 3 and 4. Next, the gas 43 through the valve 38 is fed nitrogen, under high pressure. With the help of the fan 37, the heat carrier is forced to circulate in a closed loop of the vulcanizer. At the same time, the heat transfer medium from the chamber 43 is fed into the elastic diaphragm 25 through the heated channels 41, the chamber 42 and the holes 30, and out of the diaphragm through the holes 31.

    After the end of vulcanization, the vulcanizer is placed in the loading position, where the opening of the bayonet lock 18, the upper half-mold 4 and the sleeve 44 are lifted. When lifting the sleeve 44 pushes the vulcanized tire 45 out of the lower half-mold 3.
    The proposed vulcanizer does not require its permanent connection with the external heating system and compression of the gaseous heat carrier, and after loading and closing the molds in the recharge position, it is completely independent of any external equipment, which allows it to be movable and located in any suitable place. place
