Abstract
The utility model discloses a spray nozzle for spraying rotary target materials. The spray nozzle is formed by connecting a front cylinder, a middle cone and a rear cylinder; a central through hole which is formed by connecting a rear conical hole and a front cylindrical hole is formed in the middle of the spray nozzle; the external diameter of the rear conical hole is reduced sequentially from back to front; a groove is formed on the circumferential outer surface of the rear cylinder; a seal ring is arranged on the groove; the external diameter of the front cylinder is larger than that of the rear cylinder; the external diameter of the middle cone is reduced sequentially from back to front; an annular groove is formed in the axial direction of the front cylinder; the middle cone extends into the annular groove; and a tungsten material layer is inlaid on the front cylindrical hole and one part of the rear conical hole. The spray nozzle has long service life, and can improve the spray quality of the rotary target materials.
Description
Technical field
The utility model relates to target spraying equipment technical field, especially a kind ofly sprays the nozzle that rotary target material is used.
Background technology
Rotary target material is in manufacturing processed, and it must carry out plasma spraying on the basis of tubular metal base material, when carrying out plasma spraying; The nozzle that is contained in the spray gun front end is a very crucial device, and its structure and material directly influence the coating quality of rotary target material, and traditional nozzle is as shown in Figure 1; It is processed by red copper, and nozzle is formed by connecting anterior right cylinder 1a, middle part right cylinder 2a, rear portion right cylinder 3a, is provided with a central through hole 4a who is formed by connecting tapered hole 41a and cylindrical hole 42a between wherein; The external diameter of anterior right cylinder 1a is greater than rear portion right cylinder 3a external diameter; Middle part right cylinder 2a external diameter is less than rear portion right cylinder 3a external diameter, and rear portion right cylinder 3a circumferential exterior surface is provided with groove, and sealing-ring 5a is housed on the groove; The nozzle of this structure in use water coolant mainly forwardly flows between right cylinder 1a aft end face, middle part right cylinder 2a outside surface, the rear portion right cylinder 3a outside surface; Front end cooling performance to anterior right cylinder 1a is not ideal enough, and is during owing to spraying, high through the plasma temperature of nozzle central through hole 4a; Front end cooling to anterior right cylinder 1a is bad; Be in anterior right cylinder 1a intermediary cylindrical hole 42a and will cause ablation, the back copper material of ablating is just along with powder is sprayed onto on the tubular metal base material of rotary target material, and the coating of rotary target material is polluted; Reduce the quality of rotary target material, also reduce the work-ing life of nozzle simultaneously.
The utility model content
The technical problem that the utility model will solve provides a kind of nozzle that rotary target material is used that sprays, and its long service life can improve the coating quality of rotary target material.
For achieving the above object; The technical scheme of the utility model is: a kind ofly spray the nozzle that rotary target material is used, mainly connected and composed by anterior right cylinder, middle part cone, rear portion right cylinder, the centre is provided with back taper hole and the anterior cylindrical hole central through hole that is formed by connecting; The external diameter in back taper hole by after reduce successively forward; Rear portion right cylinder circumferential exterior surface is provided with groove, and sealing-ring is housed on the groove, and anterior cylindrical external diameter is greater than rear portion right cylinder external diameter; The external diameter of middle part cone by after reduce successively forward; Anterior cylinder axis upwards is provided with annular recesses, and the middle part cone extend in the said annular recesses, and the part with the back taper hole on the said anterior cylindrical hole is inlaid with one deck tungsten material layer.
Further improve, described middle part cone outside surface is a stepped appearance, increases the contact area of middle part cone outside surface and water coolant, improves radiating effect.
Further improve, described middle part cone outside surface is provided with the multiple tracks annular recesses, and the same contact area that increases middle part cone outside surface and water coolant improves radiating effect.
The utility model since forwardly cylinder axis upwards be provided with annular recesses; The middle part cone extend in the said annular recesses; Water coolant can get in the anterior cylindrical annular recesses anterior right cylinder is cooled off, and improves the cooling performance of anterior right cylinder front end, simultaneously on described anterior cylindrical hole, is inlaid with one deck tungsten material layer with the part in back taper hole; Because the fusing point of tungsten material layer is higher; Reduce the ablation of nozzle central through hole to greatest extent, prevent that the metallic substance of nozzle is sprayed onto with powder on the tubular metal base material of rotary target material, guarantee the purity of target coating; Improve the coating quality of rotary target material, prolong the work-ing life of nozzle simultaneously.

Fig. 2 is first kind of embodiment sectional view of the utility model.
Fig. 3 is second kind of embodiment synoptic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.
Embodiment one: shown in Figure 2, a kind ofly spray the nozzle that rotary target material is used, and mainly connect and compose by anterior right cylinder 1, middle part cone 2, rear portion right cylinder 3; The centre is provided with the central through hole 4 that is formed by connecting back taper hole 41 and anterior cylindrical hole 42; The external diameter in back taper hole 41 by after reduce successively forward, right cylinder 3 circumferential exterior surface in rear portion are provided with groove, and sealing-ring 5 is housed on the groove; The external diameter of anterior right cylinder 1 is greater than rear portion right cylinder 3 external diameters; The external diameter of middle part cone 2 by after reduce successively forward, anterior right cylinder 1 axially is provided with annular recesses 11, middle part cone 2 extend in the said annular recesses 11; Part with back taper hole 41 on the said anterior cylindrical hole 42 is inlaid with one deck tungsten material layer 6, and cone 2 outside surfaces in middle part are stepped appearance.
Embodiment two: shown in Figure 3, what they were different with embodiment one is that middle part cone 2 outside surfaces are provided with multiple tracks annular recesses 21.
Below only be two preferred embodiments of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
Claims (3)
1. one kind sprays the nozzle that rotary target material is used; Mainly connect and compose by anterior right cylinder, middle part cone, rear portion right cylinder; The centre is provided with back taper hole and the anterior cylindrical hole central through hole that is formed by connecting, the external diameter in back taper hole by after reduce successively forward, rear portion right cylinder circumferential exterior surface is provided with groove; Sealing-ring is housed on the groove; Anterior cylindrical external diameter is characterized in that greater than rear portion right cylinder external diameter: the external diameter of middle part cone by after reduce successively forward, anterior cylinder axis upwards is provided with annular recesses; The middle part cone extend in the said annular recesses, and the part with the back taper hole on the said anterior cylindrical hole is inlaid with one deck tungsten material layer.
