Description
Technical field
The present invention relates to a kind of mixing yoghurt method, more particularly to a kind of mixing yoghurt side of marine propeller
Method, belongs to the technical field of marine propeller processing.
Background technology
China turns into the first in the world shipbuilding big country already, is making the country prosperous and is developing to shipbuilding.Current China shipbuilding gross ton digit
It is sure to occupy the first in the world.With the arrival in ocean epoch, Shipping industry be in the important stage of the development of great-leap-forward, it is necessary to
A large amount of high-performance ships, and requirement to ship and its parts quality also more and more higher.Therefore, for the power of propeller material
Learn performance, the importance of anti-Cavitation and embody also obvious all the more.Propeller constantly produces vacuole during Ship Propeling,
The negative pressure explosion that vacuole is produced is produced to propeller surface is up to hundreds of MPa to 1000MPa pulse stress, in seawater corrosion, sky
Bubble is degraded under the reciprocation with stress corrosion, and propeller blade can greatly shorten service life or even be broken.It is long-term with
Come, vacuolus denudation, seawater corrosion and stress corrosion is considered as the problem of being difficult to be solved, many research institutions are from propulsion system
Structural point set out, starting with from structure solves the problems, such as vacuolus denudation, but effect is not good always, could not solve the vacuole of propeller
Degrade problem.From the sixties in last century, foreign countries develop Cr-Ni-Mo systems stainless steel, Fe-Mn-Al alloys, cermet,
The material of the seawater corrosion resistances such as Ti-Ni alloys, anti-vacuolus denudation, but rarely found have the copper alloy as propeller material.It is domestic
It is outer to have scholar to metal material surface chromium plating process, find that corrosion resistance is 7~8 times of mother metal by polarization curve research, use
Life-span improves 2~6 times, and built-up welding, laser cladding method formation copper alloy propeller material are carried out in the bronze propeller materials of Ni-Al
The protection of anti-cavitation corrosion coating, but many technique and method be restricted to hundreds of kilograms or even tens tons of the propeller application of weighing
With limitation.According to relevant Literature Consult, from last century the eighties, external some scholars of the country are sprayed to propeller material surface
Apply, surface is modified work and has carried out more detailed research, obtains beneficial result of the test, but entity spiral oar is not answered
With research.But these researchs are all relatively more early, fail to solve the problems, such as the surface property of propeller well.
Manufactured more than marine propeller of the prior art by the way of casting, because blade thickness is change so that
Casting technique is stricter, and this paddle is also easier fracture in use, if using the cast of stainless steel,
Its technological requirement is higher.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of mixing yoghurt method of marine propeller, the processing
Method is easy to operate, and the processing method makes machined material occur violent plasticity change by the strong agitation effect of stirring-head
It is shape, mixing, broken, realize the densification of microstructure, homogenization and refine, marine propeller quality is significantly improved,
Propeller case hardness lifting 20%；Material yield performance boost 50%；Tensile strength lifting 20%；Material elongation percentage is lifted
30%。
In order to solve the above-mentioned technical problem, the mixing yoghurt method of a kind of marine propeller of the invention, including as follows
Step：
A. the shape of blade is gone out according to Design of Propeller from nickel-aluminum bronze material；
B. blade is polished, polished；
C. the paddle and leaf after polishing, polishing are covered into clamping and positioning, and one is connected into by stirring friction-welding technique
Body.
The mixing yoghurt method of above-mentioned marine propeller, wherein, when agitating friction is welded in step D, stirring-head
Rotating speed be 1100-1220rpm.
The mixing yoghurt method of above-mentioned marine propeller, wherein, it is right when agitating friction is welded in the step D
Paddle and leaf set are heated, and heating-up temperature is 240-640 DEG C, and keeps the temperature to terminate to welding；Meanwhile, to paddle and leaf
The cooling water that weld spray temperature is -5 DEG C is covered, and ultrasonic wave is sent to paddle and leaf set, the power of ultrasonic wave is 4000W,
50Khz.
Beneficial effects of the present invention：
The present invention passes to ultrasonic wave, and pass through by being heated in stir friction welding process to blade and leaf set
Cool water shower, is improved the mobility and plastic deformation ability of Cu alloy material, refined material microstructure,
Homogenization and densification, so as to substantially increase the performance of marine propeller, make propeller case hardness lift 20%；Material is bent
Take performance boost 50%；Tensile strength lifting 20%；Material elongation percentage lifting 30%.
Advantage mainly may be summarized to be it is following some：
(1) solid-state is connected：Without thick solidified structure and melting welding defect, it is possible to achieve with specific microstructure material
Welding；
(2) heat input is small：Thermal deformation and residual stress are small, it is possible to achieve the precision welding of large-scale frame structure；
(3) manufacturing cost is low：Without bevel and special cleaning before weldering, without metal packing, protective gas or solder flux,
Energy expenditure is than fusion welding reduction by 80%；
(4) weld seam apparent mass is good：Postwelding workpiece surface is smooth, is dripped without obvious weld flush and weldering, without sequent surface
Processing；
(5) mechanical property is good：The performances such as fatigue, fracture and bending are substantially better than fusion welding, and joint mechanical property it is each to
The same sex.
