Description
Technical field
The present invention relates to spraying technology fields, and in particular to a kind of elongated bore Workpiece painting constructing device and application its
Spraying method.
Background technique
With the rapid raising of China's economic development and living standards of the people, China's electrical energy demands are risen year by year.2013
Analyzing Total Electricity Consumption adds up 5,322,300,000,000 kilowatt hours, increases by 7.5% on a year-on-year basis, is up to 10 ~ 11,000,000,000,000 to the year two thousand thirty whole nation electricity demand
Kilowatt hour is up to 12 ~ 15,000,000,000,000 kilowatt hours to the year two thousand fifty whole nation electricity demand.For a long time, coal is in China's energy-consuming knot
Leading position is constantly in structure, the energy consumption structure based on coal and extensive growth pattern are to China's ecological environment
Cause great threat.Global carbon dioxide total emission volumn reaches 36,000,000,000 tons or more at present, creates history new record.Wherein, carbon
The maximum country of total emission volumn is China, accounts for 29%, carbon emission amount is also above European Union per capita.With the quickening of process of industrialization, ring
Border pollution and the common people have formd sharp contradiction to the promotion of environmental demand, and it is new to greatly develop wind-powered electricity generation, solar power generation etc.
The energy has become the Strategic Measure of China's energy development.
Wind energy is inexhaustible, nexhaustible one of renewable energy in nature.THE WIND ENERGY RESOURCES IN CHINA is very rich
Richness, since two thousand five, under the support of national policy, China's Wind Power Generation Industry is grown rapidly, and average annual growth rate is more than
60%, wherein being even more within 2006 ~ 2009 years the speedup development with uniform times of year or more, and became world's wind-powered electricity generation total installed capacity in 2010
The first big country of capacity.Ended for the end of the year 2014, the adding new capacity of Wind Power In China is 23351MW, accounts for the world and increases installation amount newly
45.2%, total installation of generating capacity reaches 114763MW, accounts for the world adds up installation amount 31%, occupies the first in the world.
Dead axle part in Wind turbines, stator main shaft belong to axial workpiece, are important zero in wind power generating set
Part.Currently, the wind power principal axis of mainstream is forging in the market.Compared to casting main shaft, forging main shaft is in intensity, reliability, knot
The critical aspects such as structure integrality all have higher advantage.But wind power principal axis belongs to large parts, and forging process is very
Difficulty causes its cost very high, seriously affects the overall efficiency and extensiveization application of wind generator.But, with casting in recent years
Make the rapid development of technology, casting and forging intensity, reliability, in terms of gap it is smaller and smaller, and with
Forging is compared, and the cost of casting is comparatively relatively low, such as the main shaft for a 6t being equally made or so, and is met in difference
Under the premise of technical requirement under the conditions of host manufacturer, varying environment, casting is compared with forging, unit cost can under
Drop about 60%.It, will based on the considerations of cutting down cost under the influence of wind-powered electricity generation industry rule of development itself and external market are impacted
Blower fan main shaft is changed to casting by forging and has become a kind of important trend.
And due to processing technology and the difference of standard, casting main shaft is for forging main shaft, and surface texture is more
It is loose, it is highly prone to corrode and initial failure occurs in complicated harsh working environment.Thus casting main shaft is required in table
Face carries out coating construction according to industrial heavy antisepsis standard.
Wind power principal axis belongs to long and narrow rotary structure, and length is in 3200mm ~ 4000mm, and maximum tactical diameter is about
2000mm, conventional wind power principal axis all have the inner hole at a perforation both ends, and diameter is between 300 ~ 500mm.For this kind of
When the bore area of wind power principal axis carries out coating construction, current construction means be in such a way that elongated spray boom protrudes into inner hole,
Sandblasting, spray painting processing are carried out to its surface.And since the length of inner hole of spindle is very big, elongated spray boom will after protruding into certain length
It is deformed, also, can also generate very big opposition in sandblasting and painting process to spray boom end, so that spray boom be made to produce
Raw violent shake, during the two factors will lead to practice of construction, the significantly wave of the distance of spray head to bore area
It is dynamic, and this fluctuation can then be converted into the uneven of kinetic energy when moving to bore area by the sand grains or coating of spray head ejection
Property, so that the effect of sandblasting, spray painting is difficult to ensure.And in normal construction, the distance of sand-blasting gun mouth to workpiece surface should be by
Control in the range of 100 ~ 200mm, and should try to control when constructing everywhere to workpiece surface nozzle and workpiece surface away from
From it is constant, in order to avoid cause the difference of surface spraying effect everywhere.
For minimize spray boom it is too long caused by spraying effect difference, the way of this field routine is from the two of inner hole of spindle
It holds and is respectively protruding into spray boom progress spraying application, and the mode of such gradation or section construction, there are an apparent repetitions to apply
Work area domain, i.e., the spray boom protruded into from both ends are all standing guaranteed to bore area, it will usually form a weight in inner hole middle section
Multiple construction area, in the repetition construction area, the spray boom protruded into from both ends has all carried out sandblasting and spray painting processing to it, so that the area
The spraying effect in domain is significantly different from other regions.Further, since being by several times or to be segmented in the two sides for repeating construction area
It constructs, the distance of spray head to bore area is also unable to get effective unification in practical operation, causes to repeat construction area two sides
There are spraying effect differences for bore area.
In fact, there are also a kind of special spindle structures, as shown in Figure 1, its be equipped at the small end of inner hole one it is bored
Head.For technical requirement, it is described silently need to main shaft cast and surface processing and etc. after the completion of just assembled.And it is somebody's turn to do
Diameter of bore very little silently, such as only 104mm.This stretch the spray boom with spray head can not from the small end of inner hole of spindle
Enter, therefore, the spraying application on the inner hole of spindle surface of nearly 4000mm length is only capable of being carried out by big end side.In fact, super
The spray boom for crossing 2000mm length has been difficult to normally lift for spraying application personnel, and control of not knowing where to begin more is by being located at spray
The spray head bring opposition of club head.Therefore, non-for the spraying application of the inner hole of spindle of this kind of special tectonic at present
It is often difficult.
Summary of the invention
Above-mentioned spraying effect is uneven and the technical problem of special main shaft spraying application difficulty to solve, present invention offer one
Kind elongated bore Workpiece painting constructing device and its spray-finishing construction method.The device of the invention can be good at solving inner hole of workpiece
Too long bring constructional difficulties problem, meanwhile, although the diameter of bore along main axis length direction different location is different, the present invention
Device still be able to keep spray head to the constant of workpiece surface distance, thus to bore area everywhere keep homogenization spraying imitate
Fruit.In addition, the device of the invention permission is only constructed from the side of inner hole of spindle, and can be to the surface of entire inner hole of spindle
