Abstract
The invention provides a kind of metal bellow, including bellows body, the sheath and net that are located at the hose coupling at bellows body both ends, are located on the outside of bellows body, described bellows body is U-shaped bellows；Described U-shaped bellows is prepared using following technique：Pipe manufacture, bellows shaping, shaping, heat treatment and surface treatment, described pipe use high temperature alloy as raw material.The metal bellow of the present invention, has good intensity and plasticity.
Description
Technical field
The present invention relates to a kind of metal bellow.
Background technology
Corrugated flexible hose is installed in liquid conveying system as a kind of flexible pressure-resistant pipe fitting, to compensate pipeline or machine,
The mutual displacement of equipment connection end, absorb vibrational energy, can play vibration damping, noise reduction etc. effect, have flexible, light weight,
The multinomial feature such as corrosion-resistant, antifatigue, high-low temperature resistant.Use can also be threaded.
Corrugated flexible hose can be divided into metal and rubber and plastic corrugated flexible hose according to material, and metal hose is modern industrial equipment connection
Important composition part in pipeline.Metal hose is used as electric wire, cable, the electric wire protection pipe of instrument and meter for automation signal and the people
With shower hose, specification is from 3mm to 150mm.Small diameter metal flexible pipe（Internal diameter 3mm-25mm）Be mainly used in precision optics chi it
Sense line protection, industrial sensor route protection.
There is the weak point easily to fail for metal bellow.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art part, there is provided a kind of metal bellow.
The metal bellow of the present invention, including bellows body, be located at the hose coupling at bellows body both ends, be located at ripple
Sheath and net on the outside of body, described bellows body are U-shaped bellows；Described U-shaped bellows uses following technique system
It is standby to form：Pipe manufacture, bellows shaping, shaping, heat treatment and surface treatment, described pipe use high temperature alloy as original
Material.
Preferably,
Described high temperature alloy is selected from high temperature alloy GH4202 or GH4169 alloy.
The metal bellow of the present invention, has good intensity and plasticity.
