Abstract
The utility model relates to a plasma spraying rotating target material surface dedusting cooling temperature-control device. The temperature-control device comprises an air pipe support fixed on a spraying gun. Two parallel air blowing pipes are arranged on the air pipe support. Rubber pipes are arranged on air inlets of the two air blowing pipes and are connected with an air source through a tee joint. A gas flowmeter is arranged on the tee joint. According to the temperature-control device, compressed air or compressed argon is led in through the gas flowmeter, two beams of airflow which is parallel to plasma flame flow and perpendicular to a base body are formed through the air blowing pipes. The two beams of airflow move along the left-right movement of the spraying gun to carry out sweeping on the front and the back of the plasma flame flow, and are used for sweeping away dust absorbed on the surface of a coating. Meanwhile, the temperature on the surface of the coating can be controlled through controlling of strength of the airflow, and the plasma spraying rotating target material surface dedusting cooling temperature-control device prevents the temperature on the surface of the coating from rising due to extension of spraying time, provides stable conditions for long-time continuous spraying, and improves spraying efficiency and quality of spraying target materials.
Description
Technical field
The utility model relates to the production equipment technical field of plasma spraying plated film and preparation rotary target material, especially relates to a kind of plasma spraying rotary target material surface dedusting temperature cooling.
Background technology
The plasma spraying rotary target material is that to utilize the method for plasma spraying will spray powder spray deposited on the stainless steel base of the treated mistake in surface, thereby forms the process of required target.Because plasma spraying temperature height almost can spray all refractory metals and ceramic powders; Rotary target material has the irreplaceable advantage of flat target in addition, so people begin to prepare rotary target material with the method for plasma spraying.
In the prior art, adopt spray gun to carry out plasma spraying, because spray gun extreme temperatures in the process of spraying, outlet temperature is near 10000 ℃, and flame flow velocity degree is very big, and muzzle velocity can reach 500m/s.Such first, powder instant melting when entering flame stream, and be accompanied by the heat sublimation of crossing of a part of particle, and the powder of fusion some will reflect when the directive matrix, contrajet and injection stream reason such as meet in the space causes space dust very big; Spray deposited target material surface is uneven, and specific surface is big, and the temperature height very easily adsorbs dust, causes the half-cooked dust of target inside too much like this when back and forth spraying back and forth, and voidage is bigger than normal, and easily causes layering etc., makes target of low quality; The second,, make the spraying target form segmentation crack easily because the extreme temperatures of plasma jet causes the temperature of coating surface very high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective of the prior art, and a kind of plasma spraying rotary target material surface dedusting temperature cooling that can effectively control contamination by dust and cooling, control sprayed coating surface temperature is provided.
The technical scheme of being taked is for achieving the above object:
A kind of plasma spraying rotary target material surface dedusting temperature cooling, it is characterized in that: comprise the trachea bracket that is fixed on the spray gun, two parallel gas blow pipes are installed on the described trachea bracket, on above-mentioned two gas blow pipe air inlets rubber tube is installed all, and be connected with source of the gas by threeway, in the described threeway gas flowmeter is installed.
Described two gas blow pipes are parallel with the jet axis of spray gun, and are vertical with the spraying matrix.
Described gas blow pipe internal diameter is 4-6mm, external diameter 6-10mm, and length is 100-250mm.
Described gas blow pipe pipe end when spraying remains on 15-25mm apart from the coating distance.
Distance between described two gas blow pipes remains on 40-80mm, equidistantly is fixed on the both sides of flame.
Throughput in described two gas blow pipes is controlled by gas flowmeter, generally is controlled at 20-80L/min.
It is 0.3-0.5Mpa that the utility model feeds pressure from gas flowmeter, flow is compressed air or the argon gas of 20-80L/min, form two bundles by gas blow pipe and be parallel to flame stream, air-flow perpendicular to matrix, this two bundles air-flow is followed the move left and right of spray gun and is strafed in the front and back of flame stream, the dust that is adsorbed on coating surface is removed, control the temperature of coating surface simultaneously by the size of control air-flow, make it to remain on about 150 ℃, avoided occurring the rising of coating surface temperature like this because of the prolongation of spray time, for the spraying that realizes long-time continuous provides stable condition, thereby improved the quality of spray efficiency with the spraying target.
Description of drawings
Fig. 1 is the structural representation sketch of the utility model plasma spraying rotary target material surface dedusting temperature cooling.
The specific embodiment
Below in conjunction with Fig. 1 plasma spraying rotary target material surface dedusting temperature cooling of the present utility model is described.This device comprises the trachea bracket 2 that is installed on the spray gun 5, and two parallel gas blow pipes 1 are installed on the described trachea bracket 2, and rubber tube 3 is installed on the air inlet of gas blow pipe 1, and rubber tube is connected with source of the gas 7 by threeway 4.In the threeway 4 gas flowmeter is installed.Two gas blow pipes are parallel with the jet axis of spray gun, and are vertical with spraying matrix 6.Above-mentioned gas blow pipe internal diameter is 4-6mm, external diameter 6-10mm, and length is 100-250mm, the length of the time exposing nozzle in spraying is according to the distance decision apart from coating of spray distance and gas blow pipe, and regulates by the installation site of trachea bracket 2.Under the usual condition, control gas blow pipe pipe end is 15-25mm apart from the coating distance when spraying, and the distance of two gas blow pipes is 40-80mm, equidistantly is fixed on the both sides of flame.Throughput V in the gas blow pipe is 20-80L/min, by the gas flowmeter control that connects threeway, controls the target material surface temperature T about 150 ℃ by the adjusting of spray distance and gas flow.
