Rubber transmission belt vulcanizing device and vulcanizing method thereof

Abstract

The invention discloses a rubber driving belt vulcanizing device which comprises an outer sleeve, and an upper cover plate, a lower bottom plate and a die component which are connected with the upper end surface and the lower end surface of the outer sleeve in a sealing manner. The die component comprises a pivot holder body and a die arranged at the outer ring end of the pivot holder body, a circularly communicated steam chamber is arranged on the inner surface of the die and close to the pivot holder body, an external pressure cavity is formed between the outer sleeve and the die, and the upper cover plate is adjustably connected with the lower bottom plate through a locking bolt, an inner locking bolt and a locking nut. The vulcanizing medium in the external pressure cavity is mixed with high-pressure compressed air through saturated steam, which can ensure the vulcanizing pressure and a certain temperature, the steam chamber is arranged between the die and the outer ring end of the pivot holder body, the volume of the steam chamber is greatly reduced than the volume of the internal pressure air chamber of the prior vulcanizing boiler, so that the consumption of saturated steam is greatly reduced; therefore, the steam consumption for the boiler is low, and the energy consumption is low. The device does not need a special vulcanizing boiler, so that the equipment investment is saved.

Description

technical field [0001] The invention relates to a rubber transmission belt vulcanization device and a vulcanization method using the rubber transmission belt vulcanization device. Background technique [0002] A traditional rubber transmission belt vulcanization tank is generally composed of a tank cover 01, a tank body 02, an internal pressure chamber 03, an intake and exhaust system, and a control system. See image 3 As shown, the vulcanization pressure of the transmission belt is obtained by the pressure difference between the internal pressure chamber 03 and the external pressure chamber 04, and the internal pressure chamber and the external pressure chamber are isolated by the vulcanized rubber sleeve 8. The vulcanization process of rubber requires a certain temperature (140-150°C), pressure (the unit pressure of general rubber transmission belt vulcanization is 2.0-2.2Mpa), and time. The vulcanization medium generally uses saturated steam. The vulcanization of semi-f...

AI Technical Summary

Problems solved by technology

With such a high working pressure, it is obvious that the equipment and operating costs of the boiler are too high, and the safety is reduced

Traditional vulcanization tank vulcanization, obviously the vulcanization pressure of the transmission belt is low, it is easy to cause the rubber material of the transmission belt to be poor in density and fluidity, the bonding strength between the skeleton material and the rubber is not good, the working temperature of the vulcanized rubber sleeve is high, and the service life is short

When vulcanizing the transmission belt with a thickness of 12000mm or more, the production cost of the vulcanization tank is high, the steam consumption is large, the energy consumption is high, and the waste is serious
