Description
Technical field
The invention relates to a kind of metallic hose, particularly a kind of metallic hose with better wear resistance.
Background technique
Metallic hose is the vitals in modern industry.Metallic hose is often applied to as electric wire, cable, instrument and meter for automation signal ... etc. aspect.But the wear resistance of metal current flexible pipe is poor, and need frequent replacing.
Summary of the invention
As mentioned above, namely the present invention is the problem in order to solve prior art, and provides a kind of metallic hose with better wear resistance.
Metallic hose disclosed by one embodiment of the invention, metallic hose comprises a body, two flanges, two retaining rings and a net.Flange is arranged at the opposite end of body respectively.Retaining ring folder is penetrated between body and flange.Net is socketed on the outer surface of body.Net comprises a nitride layer and a metal layer.Nitride layer is positioned at the outer surface of metal layer.The constouctional material of metal layer comprises aluminium, chromium, iron, manganese, nickel.The weight percentage of aluminium is the a% that alloy always forms, 1.19%≤a%≤3.35%.The weight percentage of chromium is the b% that alloy always forms, 11.23%≤b%≤38.23%.The weight percentage of iron is the c% that alloy always forms, 20.91%≤c%≤45.10%.The weight percentage of manganese is the d% that alloy always forms, 18.92%≤d%≤28.23%.The weight percentage of nickel is the e% that alloy always forms, 9.43%≤e%≤35.48%.a％+b％+c％+d％+e％100％。
Metallic hose disclosed by the invention described above, the net due to metallic hose has special material composition, thus has preferably wear resistance, and improves prior art institute problems faced.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present application, and form a application's part, the schematic description and description of the application, for explaining the application, does not form the improper restriction to the application.In the accompanying drawings:
Fig. 1 is the structural representation of the metallic hose disclosed by one embodiment of the invention.
Embodiment
Drawings and Examples will be coordinated below to describe the mode of execution of the application in detail, by this to the application how application technology means solve technical problem and the implementation procedure reaching technology effect can fully understand and implement according to this.
In the following description, the upper and lower, left and right used etc. are only be described for the relativeness of each assembly in graphic about the wording in direction.That is, not departing from the spirit and scope of this motion, describe first above second also can second above first.
In the following description, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the commodity of a series of key element or system not only comprises those key elements, but also comprise other key elements clearly do not listed, or also comprise by this commodity or the intrinsic key element of system.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within the commodity or system comprising described key element and also there is other identical element.
First, refer to Fig. 1, Fig. 1 is the structural representation of the metallic hose disclosed by one embodiment of the invention.As shown in the figure, metallic hose of the present invention comprises body 1, two flange 2, two retaining ring 3 and a net 4.Flange 2 is arranged at the opposite end of body 1 respectively.Retaining ring 3 folder is penetrated between body 1 and flange 2, uses the structural strength of reinforced metal flexible pipe.Net 4 is socketed on the outer surface of body 1.Net 4 comprises a nitride layer and a metal layer.Nitride layer is positioned at the outer surface of metal layer.Specifically, be first prepare an alloy, then the surface of alloy performs a nitrogenize program, and form nitride layer on surface, the part of interior position nitrogenize is then metal layer.Wherein, in the embodiment of the present invention, thickness circle of nitride layer is between 200 microns and 250 microns.In an embodiment of the present invention, the thickness of nitride layer is 230 microns.
Specifically, the constouctional material of metal layer comprises aluminium, chromium, iron, manganese, nickel.The weight percentage of aluminium is the a% that alloy always forms, 1.19%≤a%≤3.35%.The weight percentage of chromium is the b% that alloy always forms, 11.23%≤b%≤38.23%.The weight percentage of iron is the c% that alloy always forms, 20.91%≤c%≤45.10%.The weight percentage of manganese is the d% that alloy always forms, 18.92%≤d%≤28.23%.The weight percentage of nickel is the e% that alloy always forms, 9.43%≤e%≤35.48%.a％+b％+c％+d％+e％100％。
Illustrate that metallic hose of the present invention has preferably abrasion resistant effect through several embodiment below.Following table arranges the composition of the metal layer being the embodiment of the present invention and the wear test result of metallic hose respectively.
As shown above, the wear rate of metallic hose of the present invention is between 9.89*10
-6mm
3/ N*m and 4.72*10
-7mm
3between/N*m.Compared to this, the wear rate of common metal flexible pipe is then greater than 10
-5mm
3between/N*m, thus metallic hose of the present invention has good abrasiveness really.
Above-mentioned explanation illustrate and describes some preferred embodiments of the present invention, but as previously mentioned, be to be understood that the present invention is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in invention contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from the spirit and scope of the present invention, then all should in the protection domain of claims of the present invention.
