Embodiment 1

[0020] The rubber corrugated hose with joints is characterized in that: it includes a corrugated inner rubber layer, a high-elastic filling layer is arranged outside the inner rubber layer, and a plastic hose layer is arranged outside the high-elastic filling layer; between the plastic hose layer and the high-speed rail filling layer Adhesive bonding is used, and a non-woven outer sheath is provided outside the plastic hose layer; connectors are provided at both ends of the hose.

[0021] As a preferred solution, a polyethylene film is arranged between the plastic hose layer and the non-woven outer sheath.

[0022] The manufacturing method of the rubber corrugated hose with joint is as follows.

[0023] The first step is to form the corrugated inner rubber layer on the surface of the mandrel on the molding machine, add a positioning block near the hook end of the tube core, and design a connector tooling according to the shape and size of the tube core, heat the tube core and ...

Abstract

A rubber corrugated hose with a joint and a manufacturing method thereof relate to the technical field of rubber products, in particular to a rubber corrugated hose with a joint and a manufacturing method thereof. A rubber corrugated hose with joints, characterized in that it includes a corrugated inner rubber layer, a high-elastic filling layer is arranged outside the inner rubber layer, and a plastic hose layer is arranged outside the high-elastic filling layer; the plastic hose layer and the high-speed rail filling layer Adhesive bonding is used between them, and a non-woven outer sheath is provided outside the plastic hose layer; connectors are provided at both ends of the hose. The rubber corrugated hose with joints and its manufacturing method provided by the present invention; the joint head is installed immediately after the plastic hose is formed, so that the joint head and the rubber hose are connected tightly and seamlessly, and the water seepage and easy connection between the existing rubber hose and the joint head are solved. Corruption problem.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a rubber corrugated hose with joints and a manufacturing method thereof. Background technique [0002] Rubber hoses are generally used in radiators, air conditioners, and heating pipes of various vehicles such as automobiles, locomotives, and ships, and vehicles. The structure of the steel wire braided rubber hose is composed of a liquid-resistant synthetic rubber inner rubber layer, a middle rubber layer, a steel wire braided reinforcement layer I or II or III, and a synthetic rubber outer rubber layer with excellent weather resistance. Steel wire reinforced hydraulic rubber hose is mainly used for mine hydraulic support and oil field mining, suitable for engineering construction, lifting transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanized and automated hydraulic pressu...
