Description
Technical field
The present invention relates to Electrostatic Spray Technology field, more particularly to a kind of finishing electrostatic powder spraying method.
Background technology
Electrostatic spray is that, using the coated article of ground connection as anode, equipment high-tension electricity grid are connected as negative electrode, electrostatic gun
Negative high voltage, in two interpolars formation high-voltage electrostatic field, negative electrode produces corona discharge, makes the coating particle of ejection powered, and further
Atomization, by identical charges repel each other, the principle that there is a natural attraction between the sexes makes powered coating particle be inhaled in the presence of electrostatic field along power line direction
A kind of process sticked to after attached coated article, electric discharge on coated article.
At present, because electrostatic gun is that, directly by high voltage control, inconvenience directly controls the spraying feelings of electrostatic gun during operation
Condition, so it sometimes appear that coating atomizing effect is poor, the not high defect of deposition.Especially, when workpiece surface has spill
During structure, relatively depth or the narrower concave structure of gap, its surface is often difficult to attaching powder.
The content of the invention
The technical problem existed based on background technology, the present invention proposes a kind of finishing electrostatic powder spraying method.
A kind of finishing electrostatic powder spraying method proposed by the present invention, comprises the following steps：
S1, scanning workpiece to be sprayed, set up 3 D workpiece model；
Any one section of camber line, its central point position in S2, the first mask for setting up totally-enclosed cladding part model, the first mask
In part model side, or, its central point is located remotely from the side of part model but its centering angle is less than 90 degree；
At least one chamber is formed between S3, the first mask and part model, for each chamber, sets up and covers in it
Any one section of camber line in second mask of wall, the second mask, its central point is located in chamber and centering angle is less than 180 degree；
S4, by can coordinate in the first mask the second mask formation closed space part substituted with corresponding second mask,
First mask and the second mask are compounded to form assessment mask；
At least one spray chamber is formed between S5, assessment mask and part model, for each spray chamber, injection is set up
Model；
S6, according to jet model with assessing the interface of mask determine to dust entrance, and it is true according to jet model center line
Surely dust incident direction；
S7, according to dusting, entrance and incident direction of dusting adjust the first electrostatic gun, are dusted to workpiece to be sprayed.
Preferably, in addition to step S8, by the second electrostatic gun to the overall electrostatic dusting of workpiece to be sprayed；First electrostatic
The bore of spray gun is less than the bore of the second spray gun.
Preferably, the bore of the first electrostatic gun is less than or equal to 1/10th of the bore of the second spray gun.
Preferably, the bore of the first electrostatic gun is 1 the percent of the bore of the second spray gun.
Preferably, in step S1, with infrared light scanning workpiece to be sprayed.
In the present invention, by the first mask, a cladding part model and the smooth curved surface of entire teachings are established, and lead to
Cross the first mask and part model is compound, mark the chamber structure on workpiece.By by setting up the second mask, to workpiece table
The concave structure in face is estimated；The restrictive condition of second mask, is conducive to part model surface relatively depth or is open narrower
Concave structure protrusion.By the way that the first mask and the second mask are compounded to form into assessment mask, by relatively depth on workpiece or open
The narrower chamber structure of mouth is marked.
In the present invention, dust entrance and incident direction of dusting are determined according to jet model, are conducive to deeper to workpiece surface
Or the narrower chamber structure of opening dusts, solve on workpiece surface that relatively deep or narrower concave structure is difficult asking for attached powder
Topic.
In the present invention, the limitation mode of the first mask, it is to avoid have larger fluctuating in the first mask, that is, avoid the first illiteracy
There is the relatively deep or narrower chamber structure of opening on layer.
Brief description of the drawings
Fig. 1 is a kind of finishing electrostatic powder spraying method flow diagram proposed by the present invention.
Embodiment
A kind of reference picture 1, finishing electrostatic powder spraying method proposed by the present invention, comprises the following steps.
S1, scanning workpiece to be sprayed, set up 3 D workpiece model.In present embodiment, with infrared light scanning work to be sprayed
Part.
Any one section of camber line, its central point position in S2, the first mask for setting up totally-enclosed cladding part model, the first mask
In part model side, or, its central point is located remotely from the side of part model but its centering angle is less than 90 degree.First mask
Limitation mode, it is to avoid have larger fluctuating in the first mask, that is, avoid having in the first mask relatively deep or be open narrower
Chamber structure.
At least one chamber is formed between S3, the first mask and part model, for each chamber, sets up and covers in it
Any one section of camber line in second mask of wall, the second mask, its central point is located in chamber and centering angle is less than 180 degree.
In present embodiment, by the first mask, a cladding part model and the smooth curved surface of entire teachings are established, and
And it is compound by the first mask and part model, mark the chamber structure on workpiece.By by setting up the second mask, to work
The concave structure on part surface is estimated；The restrictive condition of second mask, is conducive to part model surface relatively depth or opening
The protrusion of narrower concave structure.
S4, by can coordinate in the first mask the second mask formation closed space part substituted with corresponding second mask,
First mask and the second mask are compounded to form assessment mask.
By the way that the first mask and the second mask are compounded to form into assessment mask in present embodiment, by relatively deep on workpiece or
