Problems solved by technology

[0005] The invention can solve the problem that the steel wires are poorly arranged and not tightly arranged during the steel wire winding process of the existing rubber hose, and there are many gaps between adjacent winding layers, resulting in poor strength and easy rupture of the high-pressure rubber hose. , Moreover, when the existing steel wire rope is wound, the steel wire is usually not soaked with glue. After the wire rope is wound, it is difficult for the glue to penetrate into the gap between the steel wire ropes, causing the high-pressure hose to break easily when it is stressed, affecting the rubber hose. service life and other problems

Embodiment Construction

[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0038] Such as Figure 1 to Figure 6 Shown, a kind of high-pressure rubber hose manufacturing method comprises the following steps:

[0039] S1. Inner tube extrusion: Extrude the inner rubber tube through the extruder;

[0040] S2. Sleeve core: First, evenly coat the mold release agent on the hard core, then put the inner rubber tube extruded in step S1 on the hard core, and install the hard core on the placement device 2;

[0041] S3, multi-layer winding: use the winding device 3 to spirally wind the steel wire rope on the outside of the inner rubber hose in step S2 according to the winding angle, and the number of winding layers is an even number, and the direction of rotation of adjacent winding layers is opposite;

[0042] S4. Extrusion of the...

Abstract

The invention relates to a high-pressure rubber pipe producing and manufacturing method. A bottom plate, a containing device and a winding device are included. The containing device is arranged at theupper end of the bottom plate, and the winding device is arranged above the containing device and arranged on the bottom plate. The high-pressure rubber pipe producing and manufacturing method can solve the problems that in the existing rubber pipe steel wire winding process, the steel wire arranging effect is poor, arranging is not tight, more gaps exist between adjacent winding layers, consequently, the strength of a high-pressure rubber pipe is poor, the phenomena of fracturing and the like are likely to happen, during existing steel wire rope winding, a steel wire is commonly not immersedin glue liquid, after steel wire rope winding, the glue liquid difficultly seeps into the gaps between the steel wire ropes, consequently, the phenomenon of fracturing is likely to happen when the high-pressure rubber pipe is stressed, and the service life of the rubber pipe is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of high-pressure rubber hose production, in particular to a manufacturing method for high-pressure rubber hose. Background technique [0002] High-pressure hoses are used to transport petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsified liquid, oil-water emulsion, water), etc. and liquid transmission pipelines. The structure of the high-pressure rubber hose is mainly composed of an inner rubber layer, a middle rubber layer, four or more layers of alternately wound steel wire reinforcement layers and an outer rubber layer. The inner rubber layer has the function of making the conveying medium withstand pressure and protecting the steel wire from erosion. The outer rubber The layer protects the steel wire from damage, and the steel wire layer is the skeleton material for reinforcement. [0003] At present, the existing high-p...
