Below in conjunction with accompanying drawing, embodiment provided by the invention is elaborated.
Figure 1 shows that the structural representation of the element of winding 1, need to carry out metal spraying at its end face 11, on sidewall 12, do not need to affix metal dust.Existing metal spraying technology please refer to Fig. 2, and the element of winding 1 is contained in metal framework 3, and the end face 11 of the element of winding 1 is towards metal spraying machine mouth 2.Metal spraying machine mouth 2 moves up and down, and metal framework 3 moves left and right, and the track of result metal spraying machine mouth 2 processes as shown in Figure 3, is zigzag, and as can be seen from Figure, except the end face 11 of the element of winding 1, other regions are also sprayed metal dust.That is to say, the surface of the space between the element of winding 1 and metal framework 3 all can be sprayed metal dust, causes the waste of a lot of metal dusts, and metal dust is easily adsorbed on the sidewall 12 of the element of winding 1, and the later stage needs special cleaning.
Please refer to Fig. 5, the application's metal spraying method, it is that two elements of winding 1 are put together side by side, their sidewalls 12 spacing are not more than 5 millimeters, be preferably 1～3 millimeter, keep end face 11 in same level, adjust the metal spraying machine mouth 2 of metal spraying device to the distance and bearing of the element of winding 1 end face 11, in metal spraying process, guarantee that metal spraying machine mouth 2 is to the constant distance of the element of winding 1 end face 11.In the present embodiment, metal spraying machine mouth 2 is positioned at the top of the element of winding 1 end face 11, and certainly, the element of winding 1 and metal spraying machine mouth 2 also can be in horizontal directions, and metal spraying machine mouth 2 is positioned at the dead ahead of the element of winding 1 end face 11 in such cases.
Two elements of winding 1 are placed on whirligig 5, by whirligig 5, drive rotation, and whirligig 5 is engraved structure, facilitates air-flow to pass through.Periphery at two elements of winding 1 is also arranged with housing 6, and the metal dust that can prevent from not being sprayed on end face 11 further spreads to periphery.Metal spraying machine mouth 2 moves reciprocatingly and carries out metal spraying 11 of two elements of winding, 1 end faces, makes two elements of winding 1 carry out rotation simultaneously, and the direction of rotation of two elements of winding 1 is contrary.Refer to Fig. 6, Fig. 6 is the schematic diagram in the application's metal spraying region, and dash area is metal spraying region, and the left side element of winding 1 turns clockwise, and the right element of winding 1 is rotated counterclockwise, and preferably, the autobiography speed of two elements of winding 1 is identical, makes metal spraying more even.In metal spraying process, there is air-flow enter the metal spraying chamber of metal spraying device and flow out, take away the metal dust of the indoor waste of metal spraying.
Ask for an interview Fig. 7, dash area is metal spraying region, and the reciprocating distance of metal spraying machine mouth 2 is greater than the radius sum (R+R) of two elements of winding 1, is less than the diameter sum (2R+2R) of two elements of winding 1.Because the area in space between the element of winding 1 of metal spraying region covering is less, so the metal dust amount of waste is reduced greatly.And the element of winding 1 do not stop rotation, metal dust is difficult for being adsorbed on its sidewall 12.
In order to contrast the proportion of goods damageds of metal powder material of existing metal spraying technology and the application's new metal spraying method, do following calculating.The maximum gauge of the element of winding 1 is 12.7cm at present, and minimum diameter is 5.4cm.
In existing metal spraying technology, metal spraying machine mouth 2 can be sprayed onto metal dust on metal framework 3 during near the element of winding 1 at metal framework 3 edges, so be also the region of metal powder material waste on metal framework 3.

S (metal framework)=64 * 64=4096 cm
2, this is also the metal spraying gross area.
(1) can to place the number of the element of winding of diameter 12.7cm be 18 to metal framework 3
The gross area being sprayed onto on all elements of winding is:
S (effectively)=18 * π * R
2=18 * 3.14 * (12.7/2)
2=2279 cm
2,
The gross area of metal dust waste is: S (metal framework)-S (effectively)=1817 cm
2,
To the metal dust area of wasting on each element of winding, be on average: 1817/18=100.9 cm
2,
The effective area of an element of winding is: π * R
2=126.6 cm
2,
So, the ratio of element of winding waste area of every metal spraying and effective area is: 100.9/126.6=0.796.
(2) can to place the number of the element of winding of diameter 5.4cm be 116 to metal framework 3
The gross area being sprayed onto on all elements of winding is:
S (effectively)=116 * π * R
2=116 * 3.14 * (5.4/2)
2=2655.3 cm
2,
The gross area of metal dust waste is: S (metal framework)-S (effectively)=1440.7 cm
2,
To the metal dust area of wasting on each element of winding, be on average: 1440.7/116=12.4 cm
2,
The effective area of an element of winding is: π * R
2=22.9 cm
2,
So, the ratio of element of winding waste area of every metal spraying and effective area is: 12.4/22.9=0.54.
(3) ask for an interview Fig. 8, with reference to size in figure, adopt the application's metal spraying method, as can be seen from Figure:
S3＜(S1＋S2)÷2。S3 represents actual metal dust waste region.
With respect to the diameter of the element of winding, the gap of two elements of winding is very little, for ease of calculating, in calculating, approximate the regarding as in two element of winding edges is close together, and regards S1 and S2 as separated by the element of winding two parts.
S1=S2=(2R * 2R-π * R
2) ÷ 2=0.43R
2, 2R * 2R represents area, π * R
2the area that represents great circle in square.
So, S3 < 0.43R
2,
S3 is the metal dust area of two elements of winding waste, so, to the metal dust area of wasting on each element of winding, is on average: 0.43R
2/ 2=0.215R
2, be in fact less than 0.215R
2.
The effective area of an element of winding is: π R
2,
So, the ratio of element of winding waste area of every metal spraying and effective area is:
0.215R
2/ (π R
2)=0.068, in fact ratio is less than 0.068.
The application's metal dust waste area and the ratio of effective area are much smaller than the ratio 0.796 and 0.54 of existing metal spraying technology, so the waste of metal dust reduces greatly.
