Description
Technical Field
The invention belongs to the field of tire production, and particularly relates to a tire vulcanizing device and a tire vulcanizing method for adjusting hot nitrogen supply according to a vulcanizing effect.
Background
As is known, the process of tyre vulcanisation consists in placing a green tyre in a heated vulcanisation mould, the inside of which is pressurized and heated by a bladder filled with an internal pressure medium mounted in a central organ.
For the internal pressure medium, the tyre manufacturing industry gradually changes from a hot water vulcanization process of sequentially filling steam and hot water into the bladder to a nitrogen vulcanization process of filling steam and nitrogen, and the common characteristics of the two process modes are that certain heat is provided for the green tyre by the steam, and then the pressure in the bladder is increased by other media. The common defects of the two process modes are that the pressure (internal pressure) in the capsule is greatly changed when the two media are switched, and the existing nitrogen-filling vulcanization process which is commonly adopted easily causes uneven distribution of the temperature field in the capsule due to condensed water generated by steam and the like. At present, some tire manufacturers at home and abroad begin to research a vulcanization process only using hot nitrogen in a capsule, but the problems of long tire vulcanization period and the like are caused by insufficient heat provided by the nitrogen.

The technical scheme adopted by the invention for solving the technical problems is as follows:
a vulcanized tyre device for adjusting hot nitrogen supply according to vulcanization effect is provided with a vulcanization mould and a capsule, and is characterized in that an inner cavity of the capsule is respectively communicated with a high-pressure nitrogen storage tank through an air inlet pipe, a three-way valve and an internal pressure regulating valve, the other air inlet of the three-way valve is connected with one end of a shaping regulating valve, and the other end of the shaping regulating valve is connected with the low-pressure nitrogen storage tank; and the capsule air outlet pipe is provided with an internal temperature detection device and an internal pressure detection device. The gas outlet of the low-pressure nitrogen storage tank is communicated with the inner cavity of the high-pressure nitrogen storage tank through a supercharging device, the high-pressure nitrogen storage tank is provided with a high-pressure tank pressure detection device and a high-pressure tank temperature detection device, and the high-pressure nitrogen storage tank is internally provided with a heating device.
The invention can also be realized by the following measures:
and an internal pressure emptying valve is arranged on the air outlet pipe.
And a nitrogen supplementing valve is arranged on the low-pressure nitrogen storage tank.
A tire vulcanization method for adjusting hot nitrogen supply according to vulcanization effect by using the tire vulcanization device is characterized in that a supercharging device is arranged between a low-pressure nitrogen storage tank and a high-pressure nitrogen storage tank to maintain the pressure in the high-pressure nitrogen storage tank within a set range; a temperature control device is arranged on the high-pressure nitrogen storage tank to ensure the temperature in the tank to be stable; during the tire vulcanization process, the internal pressure regulating valve provides hot nitrogen with stable pressure and temperature for the bladder; the nitrogen flow flowing through the bladder is adjusted by the internal pressure nitrogen flow adjusting valve according to factors such as the outlet temperature of the bladder, so that the stability of the internal pressure is ensured in the whole tire vulcanization process, and the heat provided for the bladder is changed according to the vulcanization effect.
The invention has the advantages that hot nitrogen is used as the only medium in the bladder in the tire vulcanization process, and the flow of the nitrogen flowing through the bladder is adjusted according to the factors such as the outlet temperature of the rubber bladder, so that the vulcanization internal pressure in the bladder is ensured to be stable and unchanged in the whole vulcanization process, and heat is supplied to the bladder according to the vulcanization effect adjustment of the tire, so that the tire quality is improved, the vulcanization period is shortened, and the energy consumption is reduced.
