Abstract
An example of a piping structure of a tire vulcanizer to which the present invention is applied has a central mechanism 1 of the tire vulcanizer as illustrated in FIG. 1. The central mechanism 1 has a bug head 2, a hydraulic cylinder 3, and exhaust circulation path pipes 4. In addition, the central mechanism 1 has a bladder (not illustrated) which may be expanded and contracted as a vulcanizing medium is supplied into the bladder. One end of the exhaust circulation path pipe 4 is connected to an interior of the bladder, and the two exhaust circulation path pipes 4 are connected to each other through a bypass pipe 5. The other end of the exhaust circulation path pipe 4 is connected to an exterior of the central mechanism 1.
Claims5
A piping structure of a tire vulcanizer,
- the piping structure comprising:
- a medium supply path which communicates with an interior of a bladder for heating and pressing a raw tire, and supplies a high-temperature and high-pressure fluid into the bladder;
- a medium discharge path which communicates with the interior of the bladder, forms a circulation path for gas between the interior of the bladder and the medium discharge path, and discharges the gas to the outside;
- and
- a circulator which is provided on the medium discharge path, and circulates the gas in the circulation path when the raw tire is vulcanized by the bladder.
A circulator which is provided on a medium discharge path, which forms a circulation path for gas between the medium discharge path and an interior of a bladder for heating and pressing a raw tire and discharges the gas to the outside, and circulates the gas in the circulation path when the raw tire is vulcanized by the bladder.
A method of vulcanizing a tire with a tire vulcanizer the method comprising:
- supplying a high-temperature and high-pressure fluid into a bladder for heating and pressing a raw tire;
- and
- circulating the gas in a circulation path for gas which is formed between a discharge path for gas and an interior of a bladder when the raw tire is vulcanized by the bladder.
