A kind of processing method of rubber hose

Abstract

The invention discloses a processing method of a rubber hose, which relates to the field of rubber processing, including six process steps of extruding a rubber layer, weaving a stressed skeleton, wrapping a rubber hose, cutting and shaping, vulcanizing, and stripping and embossing. In the feeding extruder, the rubber tube blank is extruded and placed on the polyimide acid soft mandrel for molding. The produced rubber tube is resistant to high temperature and fire, with high productivity and low energy and water consumption. The production area is small. Put the cut rubber hose into the microwave vulcanization device, quickly heat up to the vulcanization temperature, and then enter the hot air tank for secondary vulcanization to vulcanize again, which shortens the rubber vulcanization time and has better heating uniformity, which improves the automation of product processing. degree.

Description

technical field [0001] The invention relates to the field of rubber processing, in particular to a rubber hose processing method. Background technique [0002] With the development of society, rubber hoses have been used in many fields of life and production, such as petroleum industry, metallurgical industry, chemical industry, etc. At present, there are many kinds of rubber hoses on the market, and their processing methods are also different. For example, the application number is 201110200319.5. A rubber hose production process is disclosed, which includes the following steps: according to the size requirements of the rubber hose, select a capsule of the corresponding specification, and directly form it on the surface of the capsule. Put the capsule and the capsule into the pre-heated mold cavity, put the mold into the flat vulcanizer, close the mold, inject air pressure into the capsule, vulcanize, complete the vulcanization, release the pressure, take out the capsule, g...

[0002] With the development of society, rubber hoses have been used in many fields of life and production, such as petroleum industry, metallurgical industry, chemical industry, etc. At present, there are many kinds of rubber hoses on the market, and their processing methods are also different. For example, the application number is 201110200319.5. A rubber hose production process is disclosed, which includes the following steps: according to the size requirements of the rubber hose, select a capsule of the corresponding specification, and directly form it on the surface of the capsule. Put the capsule and the capsule into the pre-heated mold cavity, put the mold into the flat vulcanizer, close the mold, inject air pressure into the capsule, vulcanize, complete the vulcanization, release the pressure, take out the capsule, get the rubber tube, and produce the product Good quality, no air bubbles, lack of glue, burrs, etc. After the hose is formed, you can obtain excellent product quality without using water-wrapped cloth, making the molding process more concise and convenient, improving production efficiency and saving production costs. The processing technology cannot solve the problem of how the rubber hose can withstand high temperature and fire, how to maintain stability under high pressure working conditions, how to improve the anti-fatigue ability and anti-pulse ability of the rubber hose, ensure the overall compactness of the finished rubber hose, and shorten the rubber vulcanization time. Make its heating uniformity better, and improve the automation of product processing
