Description

a latch 13, which is initially biased to the rod 14 having a piston 15 placed in the cylinder 11. At the free end of the rod 14 there is a clamping block 16 on which the spring 17 is supported, protected by the cup 12 of the housing 10. The rod 14 has a groove 18, which interacts with the tooth latch

13, and a through hole 19 extending under the piston 15. A throttle washer 20 is fixed to the hole 19 on the rod 14 and secured with a nut 21. On both sides of the lower pressing plate 3, supports 22 are mounted along it.

Vulcanizing press works as follows.

When the upper press plate 2 is raised, the workpiece is placed on the lower press plate 3 and the supports 22. Then, moving the carriage 9 of the workpiece locking mechanism along the guides 8, install them in places where the workpiece is fixed and, removing the handle of the latch 13, remove the last the groove 18 of the rod 14. At the same time, the rod 14 under the action of the spring 17 moves vertically to the support 22, pressing the workpiece against it with the pressure pad 16. Moving down, the rod 14 with its piston 15 compresses the air below it and displaces it through the hole 19 and throttle washer 20. Such depreciation ensures the safe operation of the mechanism for fixing the workpiece on the press. Next, the blank held by the clamping pads 16 is lowered by the upper pressing plate 2 by means of the mechanism 4 for reciprocating movement and fixation. In this case, the mechanism for fixing the workpiece also moves to the lower pressing plate 3, except for the rods

14, which, resting on the support 22, are moved upwardly relative to the cylinder 11 of the housing 10, while compressing the spring 17.

When the pressing plates 2 and 3 are closed, the lever system 6, opened under the action of the pneumatic cylinder 5, locks the upper pressing plate 2 with wedge clamps 7, and the latch 13 enters the groove 18 of the shaft 14 under the action of the spring 14. Thus, the rod 14 is automatically locked in the initial position . Next, press pressure and heating of the workpiece are created. Vulcanization occurs. At the end of vulcanization, air is supplied to the pneumatic cylinder 5 of the mechanism 4 for reciprocating movement and fixation of the upper pressing plate 2 and

the wedge clamps 7 are removed, and then the upper plate 2 is raised. At the same time, all the clamps of the workpiece fixing mechanism remain in the initial position. The proposed design of a vulcanizing press will allow to mechanize the operation of holding the workpiece on the slab without supplying additional communications and expand its operational capabilities.
