Embodiment Construction

[0022] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0023] A method of processing fatigue-resistant metal hoses such as figure 1 and 2 shown, including the following steps:

[0024] Step 1, several groups of fins 11 are processed on the outer wall of the inner tube 1, each group of fins 11 is spherical, and the fins 11 are soft materials;

[0025] Step 2, machining a casing 2 whose inner diameter is consistent with the diameter of the sphere, and one end of the casing 2 is provided with a socket;

[0026] Step 3: Sleeve several sections of sleeves 2 on the inner tube 1, let a set of fins 11 enter the inner cavity of the sleeves 2, and then insert the adjacent sleeves 2 end-to-end through the plug-in parts, Form cooperation;

[0027] Step 4: Rotate the casing 2 at will to recover the compressed fins 11 in the casing 2 .

[0028] The fins 11 are made of soft rubber. A protective pad 211 is provi...

Abstract

The invention discloses a method for machining an anti-fatigue metal hose. The method comprises the following steps that 1, a plurality of groups of fins are machined on the outer wall of an inner pipe, each group of fins are integrally in the shape of a ball body, and the fins are made of flexible materials; 2, sleeve tubes with the inner diameter consistent with the diameter of the ball body aremachined, and one ends of the sleeve tubes are provided with inserting parts; 3, the multiple sections of sleeve tubes sleeve the inner pipe, one group of fins enter an inner cavity of the corresponding sleeve tube, and then every two adjacent sleeve tubes are connected in an end-to-end insertion mode through the inserting parts to form cooperation; and 4, the sleeve tubes are rotated at will, sothat the pressed fins in the sleeve tubes are restored. According to the method, the service life of the metal hose is prolonged and the metal hose is prevented from being broken and scratched.

Description

technical field [0001] The invention belongs to the field of metal hoses, in particular to a method for processing fatigue-resistant metal hoses. Background technique [0002] The metal hose is rotatable like a plastic pipe and has the hardness like an ordinary metal pipe, and the metal hose is easy to install and can ensure the relative movement requirements between the connecting parts. In many cases, we will use metal hoses. The installation environment of hoses, subways, urban underground, urban buildings and other cables is particularly harsh. Over time, the cables are prone to aging, oxidation, etc., causing damage to the cables. In the existing technology, flat-coated plastic metal hoses Generally, it includes (P3 type) metal hose and outer plastic coating. In the application process of modern society, circuit aging or other causes of fire will cause property loss on the one hand, and on the other hand, because the flat plastic metal hose is made of PPC material. The...
