Description
Technical field
It the utility model is related to coating equipment field, more particularly to a kind of batch thermal spraying apparatus of annular workpieces.
Background technology
Thermal spraying has the characteristics that easy to operate, cost is low and to prepare workpiece universal strong, in aerospace, steel, ore deposit
The fields such as production, automobile have been widely used.Thermal spraying is to utilize certain heat source (such as electric arc, plasma spraying or burning
Flame etc.) by the metal or nonmetallic materials of powder shape or silk shape be heated to melting or semi-molten form, then by flame stream sheet
Body or compressed air are ejected into pretreated matrix surface with certain speed, deposit and form the surface with various functions and apply
A kind of technology of layer.
Annular workpieces are workpiece common in thermal spray process, such as in valve industry, valve seat is the annular workpieces of standard,
The contact surface of itself and valve plate needs to carry out thermal spraying to improve wear-resisting property.Existing batch spraying method is that workpiece is arranged in
Plate shaped to be sprayed, the disadvantage of this spraying method is, when spray gun is moved to the inner hole areas of annular workpieces, spray gun
Equivalent to against aerial spraying, material and waste of time are caused.
Utility model content
The utility model is in view of the above-mentioned problems, provide a kind of batch thermal spraying apparatus of annular workpieces, it is possible to reduce ring-type
During Workpiece painting, conventional spray paint method is for material and waste of time.
To realize above-mentioned target, the utility model provides following technical solution：
A kind of annular workpieces thermal spraying apparatus, including multi-station turning table, spray coating mechanical hand, the spray gun for thermal spraying, institute
State spray gun and be installed on spray coating mechanical on hand, the spray coating mechanical hand can be along the line of centres for the workpiece being installed on multi-station turning table
Mobile, its translational speed is variable.
Crossbeam is provided with above the multi-station turning table, the spray coating mechanical hand is installed on crossbeam, can be along cross beam movement.
During the workpiece centre, its translational speed linearly increases the spray gun.
The spray gun from during a workpiece is moved to another workpiece, its translational speed for setting maximum.
For the spray gun when spraying annular workpieces, its translational speed is 3-5mm/s.
At the same time, there is provided a kind of corresponding annular workpieces heat spraying method.
Comprise the following steps：
Step 1：Annular workpieces are arranged on multi-station turning table by line-styled；
Step 2：Spray gun is moved along the line of centres of workpiece, and workpiece is sprayed；
Step 3：During the workpiece centre, its translational speed linearly increases the spray gun；
Step 4：The spray gun from during a workpiece is moved to another workpiece, its translational speed for setting most
Big value；
Step 5：Repeat step three and step 4.
Compared with prior art, the utility model has the advantages that：
The utility model annular workpieces thermal spraying apparatus, spray gun can work as spray gun in moving process medium velocity with real-time change
When being moved to the inner hole areas of annular work piece, spray gun translational speed greatly improves, and reduces spray gun in the inner hole areas of annular work piece
Residence time, so as to reduce material and waste of time.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model annular workpieces thermal spraying apparatus.
Fig. 2 sprays schematic diagram for the utility model annular workpieces thermal spraying apparatus.
Embodiment
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of annular workpieces thermal spraying apparatus, it includes a multi-station turning table 1, is on multi-station turning table 1
Linear type arranges multiple annular workpieces 4, and the top of multi-station turning table 1 is provided with crossbeam, and spray coating mechanical hand 2 is arranged at crossbeam
On, it can be moved left and right along crossbeam, spray coating mechanical hand 2 is driven by a servomotor, and spray gun 3 is provided with spray coating mechanical hand 2, is sprayed
Manipulator 2 drives spray gun 3 to move.Spray gun 3 is located at the top of annular workpieces 4, and spray gun 3 can be moved along the line of centres of workpiece, muzzle
Centring line.
It is slower closer to workpiece centre, linear velocity in the case of invariablenes turning speed due to circular workpiece.In order to protect
It is uniform to demonstrate,prove coating surface thickness, then area equation inswept in 3 equal time of spray gun is required, so the linear velocity of workpiece is got over
Slowly, the translational speed of spray gun 3 will be faster.Therefore, according to speed set in advance, closer to the center of annular workpieces, spraying
The translational speed of manipulator 2 is faster.
The region that region A needs to spray for annular workpieces, interval regions of the region B between two workpiece.
Spray gun 3 is continually changing in the speed of region A, and A areas speed is generally in the range of 3-5mm/s, closer to workpiece
Center, the linear increasing trend of speed.
Spray gun 3 is constant by the speed of region B, is traditionally arranged to be the maximum of 2 translational speed of spray coating mechanical hand.
When spraying beginning, multi-station turning table 1 is with constant speed rotary annular workpiece 4,3 moving direction of spray gun such as Fig. 2 arrows
Shown in head, when spray gun 3 is moved to region A, spray gun 3 is moved according to the speed of setting, in order to ensure that workpiece surface spraying is uniform,
Spray gun 3 is faster closer to workpiece centre, translational speed.Spray gun 3 moves back and forth for several times in A regions, reaches the spraying number of setting
Afterwards, spray gun 2 is moved to next workpiece, and spray gun 3 is at full throttle by region B, to reduce the waste of dusty spray.
Sprayed by above method, it is possible to reduce powder consumption 20% or so.
Above-listed detailed description is illustrating for the utility model possible embodiments, which simultaneously is not used to limit
The scope of the claims of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, are intended to be limited solely by this case
In the scope of the claims.
