Abstract

The invention relates to a production method of a hydraulic hose wound by four layers of steel wires. The production method includes the following steps of (1) batching, (2) internal mixing, (3) openmixing, (4) medium film calendering, (5) inner tube extruding, (6) winding, (7) external glue coating, (8) water cloth winding, (9) vulcanizing, (10) water cloth opening, (11) decoring and pressure testing, and (12) inspecting, packaging and warehousing. According to the production method of the hydraulic hose wound by the four layers of steel wires, in the production process, a raw material adopts a special material formula, the raw material cost is low, produced product performance is excellent, the good acid and alkali resistant and anti-corrosion effects are achieved, oil-resistant, heat-resistant and ageing-resistant properties are good, the four layers of steel wires are used for winding, a binder is used for bonding, the structure is compact, the bonding effect is good, service performance of the hydraulic hose is enhanced, and the service life of the hydraulic hose is prolonged; and in the technological process, heating treatment is conducted in a special mode, and circulationsupply of cooling water is realized, so that the production cost is lowered.

Description

Technical field [0001] The invention relates to a production method of a four-layer steel wire wound hydraulic hose, which belongs to the technical field of hydraulic hose production. Background technique [0002] Hydraulic hose, also known as hydraulic hose, hydraulic hose, high pressure hose, hydraulic hose, steel wire high pressure hose. Generally divided into steel wire braided hydraulic hose and steel wire wound hydraulic hose. The hydraulic hose is mainly composed of liquid-resistant inner rubber layer, middle rubber layer, 2 or 4 or 6 layers of steel wire winding reinforcement layer, and outer rubber layer. The inner rubber layer has the function of making the conveying medium bear pressure and protecting the steel wire from corrosion. The outer rubber layer protects the steel wire from damage, and the steel wire layer is the framework material for reinforcement. [0003] The hydraulic hose is generally made of special synthetic rubber, which has excellent oil resistance, ...
