The invention relates to the manufacture of pneumatic tires, is intended for the vulcanization of radial tires with steel cord in a carcass and breaker, and is an improvement of the device according to the author. St. No. 1271762.

; 11, the spruce of the invention - improving the reliability of the device in operation by eliminating local wear on the cylindrical surface of the control hydraulic cylinder

; the diaphragm.

The drawing shows the proposed device (on the left — before loading the butt-lid blank, on the right — the last stage of forming the tire), a slit.

A device for vulcanizing tires of pneumatic tires comprises a lid 1 of a steam chamber with an upper half-form 2 rigidly attached to it, forming the upper sidewall of the tire 3 and the bottom 4 of the base of the steam chamber. The cover 1 with steam ring 17 with the ring 15. The hydraulic cylinder 14 by means of an annular groove 12 and a clamp 9 lifts the lower half-form 11, which in turn supports the sector 8. When lifting the latter by

 The T-bars 7 are held in contact with the converging cone 6 and are diluted. With its radial movement of the sector 8, the output t clamps 9 from the annular groove 12. With a further rise

10 hydraulic cylinders 14 clamps 9 emerge onto the surface of vertical rods 13 (Fig. 1, left). Next, the latter are moved relative to the latches 9.

By pressing the retainers 9 into the vertical rods 13, the lower half-form 11 with sectors 8 is held in the upper position when removing the vulcanized tire (removing the diaphragm from the cavity of the vulcanized tire and removing it from the ring, the forming chamber, the base with the bottom 4 and the bottom) The edges of the bead, produced by a known tipping unit 5, are formed in a hermetic way) when installing the workpiece, a covering cavity into which heat is supplied to the bead ring 18. Next, the beater. A tire 3 is rigidly fixed to the bottom 4 on a diaphragm - a reducing cone 6. Along the forming membrane 17. The lid of the steam chamber together the reducing cone 6 are fixed T-shaped, with the upper half-form 2 lowered, shaped bars 7, the number of which corresponds - 25 tire beads 3. At the same time, the number of sectors 8 is reduced. A lower joint downward movement of the lid 1 and the hydraulic cylinder 14 with the rings 15 and 18 and vertical rods fixed to it 13. The clamps 9, moving along the rods 13, enter into the groove 12 The ring 15, 30 lowering is carried away by the fix torus 9,

and with it the lower half-form 11 together with sectors 8. The latter, descending, are reduced by the radially conical surface of the converging cone 6. At the end of the down stroke of the hydraulic cylinder 14 of sector 8 are reduced

The support surface of sector 8 is connected by a lead with a clamp 9, which is radially mounted in guides 10, made on the support surface of the lower half-form 11. The locks 9 with free ends interact during operation with both the ring groove 12 and the vertical bars 13. The latter are fixed in the upper part of the hydraulic cylinder 14 on the ring 15 opposite the fixation - ... „,,. ..

The control cylinder of the diaphragm and, consequently, its wear, which favorably affects the operation of the cylinder 14, also attaches the side 45 of the body assembly and the reliability of the ring 18, which forms the flange of the overall device.

The rod 19 of this hydraulic cylinder is rigidly connected to the disk 20 for clamping the upper flange of the diaphragm 17. The hydraulic cylinder 14 is connected to the rod of the hydraulic cylinder 2 of displacement. The device works as follows. After the end of the vulcanization cycle (Fig. 1, right), the lid 1 of the steam chamber is opened and, together with the upper half formula of the invention
