Abstract

The invention relates to the field of mine pipelines, and discloses a manufacturing method of a high-wear-resistance rubber steel wire hose and a mold forming device. The method comprises the following steps: A, preprocessing a film; B, calendering the film; C, carrying out rubber material splicing pipe body forming; D, forming a pipe orifice check ring; E, carrying out product vulcanization; and F, demolding and polishing to obtain a finished product. According to the manufacturing method, the thickness of each layer can be effectively controlled, so that easy-to-fail points are controlled in a targeted manner, and the wear resistance and the stability of the hose are improved.

Description

technical field [0001] The invention relates to the field of mining rubber hoses, in particular to a manufacturing method and a mold forming device for a high wear-resistant rubber steel wire hose. Background technique [0002] During the mining process, crushed ore needs to be transported. During the ore transport process, the transport pipeline is required to have a certain degree of mobility to compensate for pipeline installation errors. Therefore, rubber hoses are widely used in the mining industry, and rubber hoses are also required to have good wear resistance. The rubber hose is composed of a wear-resistant layer, a composite material layer, an adhesive layer, a steel wire skeleton, and an outer layer of weather-resistant rubber. [0003] At present, the market is the rubber hose forming process of pre-vulcanized rubber sheet. The rubber hose forming process of the prior art is as follows: [0004] Mix the rubber mixture according to the conventional mixing method...
