Problems solved by technology

[0008] The object of the present invention is to overcome the disadvantages of the prior art that the quality of the transmission belt deteriorates due to poor sealing effect during the vulcanization process, and to provide a transmission belt vulcanization system and its vulcanization method. There is a gas channel, and the air inlet hole of the air channel is set on the peripheral side of the cover plate, so that the gas leaked from the peripheral side of the cover plate enters the gas channel through the air inlet hole, preventing the gas from entering between the rubber sleeve and the inner mold due to poor sealing effect , so as to improve the vulcanization effect of the transmission belt

Embodiment 1

[0050] combine figure 1 , figure 2 , image 3 , Figure 4 and Figure 13 , a transmission belt vulcanization system of the present invention, comprising a vulcanization device and a vulcanization tank 400, wherein the vulcanization device is arranged in the vulcanization tank 400, the vulcanization device includes a rigid inner mold 210, a toothed rubber sleeve 220 and a cover plate, and the rigid inner mold 210 is used To support the transmission belt blank 300, the toothed rubber sleeve 220 is set on the outside of the rigid inner mold 210, and the cover plate is installed on both ends of the toothed rubber sleeve 220; the vulcanization tank 400 is provided with a first steam pipe 420, The first steam pipe 420 is connected with the vulcanization device, and the steam boiler provides steam pressure to the vulcanization device through the first steam pipe 420. The specific description is that the first steam pipe 420 is connected with the internal air pressure control pipe...

Embodiment 2

[0068] The basic content of this embodiment is the same as that of Embodiment 1, except that: the circumferential side of the cover plate is provided with an annular exhaust groove 105 (such as Figure 5-Figure 8 As shown), the exhaust groove 105 is arranged along the circumferential direction of the peripheral side, and the exhaust groove 105 communicates with the air inlet 101; the air inlet 101 is arranged in the exhaust groove 105, so that the air inlet 101 communicates with the exhaust groove 105 . At the same time, the distance between the exhaust groove 105 and the inner surface 107 of the cover plate is D 3 ,D 3 >0, the distance between the exhaust groove 105 and the outer surface 108 of the cover is D 4 ,D 4 >0 (eg Figure 8 shown). And the air inlet 101 is disposed at the center of the exhaust groove 105 .

[0069] In order to achieve a better effect and prevent the gas in the vulcanization tank 400 from infiltrating from the joint between the cover plate and t...

Embodiment 3

[0072] The basic content of this embodiment is the same as that of Embodiment 2, except that the inner diameter of the inner toothed section 222 is smaller than the inner diameter of the inner smooth section 223, so that the inner toothed section 222 protrudes inwardly relative to the inner smooth section 223, and A transition connection surface 224 is formed between the top of the inner toothed section 222 and the inner smooth section 223, and the transition connection surface 224 is also a smooth plane. When the cover plate is installed on the inner smooth section 223 of the toothed rubber sleeve 220, the cover plate The peripheral side 106 of the cover plate is matched with the inner smooth section 223, so as to realize the sealing between the peripheral side 106 of the cover plate and the inner smooth section 223, and the transition connection surface 224 cooperates with the edge part of the inner surface 107 of the cover plate to realize the The edge of 107 is sealed with ...

Abstract

The invention discloses a driving belt vulcanization system and a vulcanization method thereof, and belongs to the technical field of driving belt vulcanization. The driving belt vulcanization systemcomprises a vulcanization device which is arranged in a vulcanization tank, and the vulcanization device comprises rigid internal models, belt teeth gum covers and cover plates. The rigid internal models are used for supporting a driving belt strip plate. The rigid internal models are sleeved with the belt teeth gum covers, wherein the cover plates are installed at two ends of the belt teeth gum covers. Gas channels are arranged in the cover plates and air inlet holes of the gas channels are formed in the sides of the circumferences of the cover plates. Gas vent holes of gas channels are formed in the middle parts of the cover plates, wherein the air inlet holes communicate with the gas vent holes through the gas channels, and the gas vent holes communicate with the dies interior of the rigid internal models. A second steam pipeline is arranged on the vulcanization tank, and an air pump is arranged at the external of the vulcanization tank. According to the driving belt vulcanization system, the gas channels are arranged in the cover plates and the air inlet holes of the gas channels are formed in the sides of the circumferences of the cover plates, so that the leakage of gas fromthe circumferences of the cover plates enters into the gas channels through the air inlet holes, and the vulcanization effect of the driving belt is improved.

Description

technical field [0001] The invention relates to the technical field of transmission belt vulcanization, and more specifically, relates to a transmission belt vulcanization system and a vulcanization method thereof. Background technique [0002] As an important component in the field of mechanical transmission, V-shaped transmission belts have been widely used in automobiles, motorcycles, etc. There are two ways to make V-belts: positive forming and reverse forming. The positive forming method is as follows: choose a cylindrical steel mold with teeth on the surface as the inner mold for product molding, put the belt parison on the inner mold, put a rubber sleeve on the outside of the belt parison, and then place the rubber sleeve on the outer surface of the belt blank. Install the upper cover plate at both ends for sealing, and then put it into the vulcanization cylinder for differential pressure vulcanization, and form external pressure on the outside of the rubber sleeve, ...
