Description

technical field [0001] The invention relates to a winding rubber hose linkage production method and its device, in particular to tire extrusion, mandrel production, rubber hose freezing, steel wire winding, and related control technologies and equipment in the high-pressure steel wire winding rubber hose production process. Background technique [0002] The structure of the high-pressure steel wire wound rubber hose is mainly composed of an inner rubber layer, a middle rubber layer, 2, 4, 6 and other even-numbered steel wire wound 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 layer protects the steel wire from damage, and the steel wire (φ0.3-2.0 reinforced layer) layer is the skeleton material for reinforcement. [0003] High-pressure steel wire wound rubber hose is mainly used in mine hydraulic supports and oil field development, suita...

AI Technical Summary

Problems solved by technology

[0012] (1) The size of the tube embryo does not meet the standard requirements, and the thickness of the tube wall is uneven: improper selection of the core shape and the mouth shape, poor mixing and mastication of the rubber material, resulting in inconsistent plasticity of the rubber material; eccentricity of the core shape and the mouth shape Or improper selection, uneven heating temperature of the rubber material, poor plasticizing performance of the working screw of the extruder, all of which are likely to cause such problems

[0013] (2) The thickness of the tube blank is uneven: the plasticity of the rubber material is inconsistent, the heating temperature is uneven, the feeding speed is fast and slow, the extrusion speed and the traction speed do not match, all of which can cause the outer diameter of the tube blank to be extruded. Inhomogeneity

[0014] (3) Rupture of the rubber layer: impurities such as micelles and hard particles mixed in the rubber material, or local self-sulfurization of the rubber material may cause the rubber layer to rupture

[0015] (4) Blistering or sponge phenomenon in the rubber layer: too much water or low-molecular volatiles in the rubber material, air mixed in the rubber material or feeding, the temperature of the extruder is too high, and the screw of the extruder is severely worn and causes thrust Insufficient pressure, insufficient pressure on the head of the extruder, etc., can cause foaming or sponge phenomenon in the rubber layer

[0016] (5) Preform adhesion: Preform cooling is not enough, the effect of the release agent is poor, the preform is squeezed too tightly after extrusion, and the parking time is too long, all of which can cause preform adhesion.

[0025] ①It is too large and the price is too high, which is not conducive to the development of small and medium rubber hose enterprises; ②It is difficult to grasp the comprehensive balance angle during winding; ③It is difficult to adjust the tension of the steel wire spindle; ④The diameter of the hose after winding is too small

[0027] At present, the traction guide device and the electrical control system can realize the synchronous control of winding and traction through frequency conversion control, but there is not much consideration in the coordination and cooperation with the extrusion link, and they are still in a state of independent operation, and cannot be linked from the entire steel wire winding Full automatic control and operation from the perspective of production

Moreover, the closed-loop feedback control from the overall link of hose extrusion, vulcanization freezing, steel wire winding and traction has not been realized.

For abnormal production conditions, technical research and equipment development of fault diagnosis, monitoring and alarming have not been reported in the literature.
