Description
Technical field
The present invention relates to a kind of corrugated flexible metal tube manufacture method with shock-absorbing function, belong to metal hose field.
Background technology
Metal hose is connecting elements important in engineering technology, is combined into by corrugated flexible hoses, net cover and connector.
In various gas transmissions, infusion pipeline system and length, temperature, position and angle compensation system as compensating element, sealing element,
Connecting element and damper element, applied to aerospace, petrochemical industry, mine electronics, mechanical shipbuilding, health care, light textile
Each fields such as electronics, energy building.The newest national regulation of metal hose is《Corrugated flexible metal tube general technical specifications》（GB/
T14525-2010）, implemented in 1 day October in 2011.
Corrugated flexible metal tube（Abbreviation bellows）It is a kind of flexible duct of high-quality in modern industry pipeline.It mainly by
Bellows, net cover and connector composition.Its inner tube is the thin-wall stainless steel bellows with spiral shape or annular waveform, bellows
The net cover of outer layer, is to be formed by stainless steel wire or steel band by certain parameter braiding.The connector or flange at hose both ends be and visitor
What the connector or flange of family pipeline matched.
Corrugated flexible metal tube is from structure, and the training material of metal bellows has two clock of band and tubing, they can
Mold ring bellows and helical fissure pipe.For no other reason than that the molding bellows of band always have certain length soldering or
The hasp and connector of melting welding, these places usually accumulate the residue of working media, and precipitate to have and clean experiment and working media
In introduction of contaminants inner cavity.Therefore, its is relatively weaker using Reliability.Ring bellows is some torus membranes
The semicircular ring phase cut-grafting centripetal with some concave surfaces of piece outer rim, inner edge and the special geometric of the semicircular ring phase cut-grafting of some concave surface vests
The pipe of shape.For its blank based on tubing, this kind of bellows has the spies such as flexibility is big, elasticity is good, be simple to manufacture, rigidity is small
Point.Suitably it is used for making bearing general work pressure, to the metal hose of flexible more demanding big or middle latus rectum.Helicon wave
Line pipe be certain length diaphragm outer rim around spring shape with around the centripetal semicircular ring phase cut-grafting in the concave surface of spring shape, inner edge with around spring shape
Concave surface vest semicircular ring phase cut-grafting particular geometry pipe.This kind of bellows is with intensity is high, rigidity is big, manufacture
The features such as simple, be suitably used for making, intensity requirement higher high, middle pressure general to flexibility requirement, the metal of middle or small latus rectum
Hose.
In the prior art in order to enable metal hose to reach more preferable damping effect, can generally use in two phases
Mutually nested bellows, and vibration-absorptive material is set in two bellowss, or in a plurality of small-sized ripple arranged side by side of net cover installation
Pipe, to reach further damping effect, two bellowss of the first scheme can be caused in BENDING PROCESS it is uncoordinated, and
Also can affect to curved angular range, second scheme not only causes angle of bend scope larger shadow
Loud, simultaneously because the internal diameter of bellows diminishes, and the quantity of bellows becomes more, and follow-up installation and use are all brought
Inconvenience.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of production method of the corrugated flexible metal tube with shock-absorbing function, it is main
Want production stage as follows：
1) on multiple wave crests of ring metal bellows a plurality of recess group is suppressed along straight line；
2) the ring metal bellows suppressed, it is placed in groove corresponding with its structure, liquid rubber is poured into groove, is treated
Liquid rubber is solidified as rubber layer；
3) in rubber layer adhesion fiberglass cloth, and fast cooling makes its firm pasting；
4) two semicircle snap rings are being caught in positioned at the wave crest position of each ring metal bellows, and are being pointed to snap ring both ends
Otic placode carries out spot welding；
5) fiberglass cloth and rubber layer positioned at ring metal bellows wave trough position are cut away；
6) top connection, and the metal-coating of welding outer layer are installed at the both ends of ring metal bellows.
Further, 1）Described in recess group quantity be four.
Further, 3）In by way of spraying liquid nitrogen come fast cooling.
Further, 4）Middle spot welding method is direct welding.
Compared to the prior art compared with, the present invention in be socketed respectively by each crest location in a ring metal bellows
Endless metal overcoat, while further improving damping effect, will not impact the bending of bellows, pass through at the same time
Glass fabric is set in the inner cavity that metal-coating and bellows are formed, improve bellows crest location and metal-coating it
Between lubricity, will not be caused in BENDING PROCESS the generation of overcoat and bellows wear, add service life, further exist
Rubber ring is set to make there is certain elasticity between overcoat and bellows in its inner space, so as to reduce further inside
Loss caused by friction, while utilize the insulating properties of glass fabric, it is therefore prevented that rubber ring produces electrostatic in friction process and makes
Into accident.
