Abstract
The present invention relates to a central mixing nozzle for spraying and shaping composite materials. The present invention comprises a hyperbaric gas chamber and a middle packet. The present invention is characterized in that the center of the middle packet is provided with a delivery pipe for delivering adulterated powder materials. The outlet of the delivery pipe is sheathed in the outlet of the middle packet, and the outlet part of the delivery pipe is protruded out of the outlet of the middle packet. The present invention has the advantages that the present invention overcomes the existing disadvantages of traditional adulteration mixing nozzles. The delivery pipe of the powder materials is arranged in the center of the middle packet. Peripheral molten metal heats the powder materials, enhances the temperature of the powder materials, makes the powder materials easily bonded with the metal, and greatly improves the quality of spray shaped metal blanks.
Description
(1) technical field:
The present invention relates to the nozzle that uses in a kind of reaction-injection moulding equipment, particularly a kind of composite reaction-injection moulding center blending formula nozzle.
(2) background technology:
Reaction-injection moulding is the new technology that a kind of method that adopts rapid solidification prepares the large block body tight metal material.Its forming process is motlten metal or alloy to be atomized be the tiny liquid molten drop of size in inert atmosphere, under the drive of high velocity air, tiny liquid molten drop is directly injected on the colder recipient, and molten drop adheres to, merges, solidifies in receptor surface, forms needed shape blank.In course of injection, can improve the performance of metal, obtain high-quality blank to molten metal adulterated powder material.Traditional doping mixing nozzle structure as shown in Figure 1, motlten metal is flowed out by the bottom of tundish 1, spray in the belt slit aperture of powder body material by the powder nozzle 2 that mediates of mixing, high-pressure inert gas sprays from the belt slit aperture of outermost plenum chamber 3, make metal atomization and be deposited on the recipient after powder body material mixes, obtain needed blank.The shortcoming of this kind nozzle is that (1) powder feeding air-flow is clipped between metal flow and the high pressure draught, has influenced the uniform atomizing of high pressure draught to metal; (2) high pressure draught dispels a part of powder body material, has reduced stock utilization, has influenced the stability of blank quality.
(3) summary of the invention:
The objective of the invention is to design a kind of composite reaction-injection moulding center blending formula nozzle, it can overcome above-mentioned shortcoming, is a kind of blending formula nozzle that improves stock utilization and improve blank quality.
Technical scheme of the present invention: a kind of composite reaction-injection moulding center blending formula nozzle, comprise plenum chamber and tundish, it is characterized in that being provided with at the tundish center carrier pipe of carrying the adulterated powder material, the outlet of carrier pipe is enclosed within the outlet of tundish and the export department of carrier pipe protrudes in the outlet of tundish.
The diameter of the carrier pipe of above-mentioned said conveying adulterated powder material can be the 3-8 millimeter.
The export department of above-mentioned said carrier pipe protrudes in the outlet of tundish, and its projecting height can be at the 5-10 millimeter.
The course of work of the present invention and operation principle are: will spray in the carrier pipe of powder body material by the center that mix, and the motlten metal in the tundish is flowed out by the annular space outlet of bottom, when gases at high pressure are sprayed by the outermost layer plenum chamber, act directly on the motlten metal, improved the uniformity of atomizing.And motlten metal stream has wrapped up the powder body material that mixes, and powder body material can not dispelled by high pressure draught, has also improved the uniformity that powder body material mixes simultaneously.
Superiority of the present invention is: overcome the shortcoming that traditional doping mixing nozzle exists, the carrier pipe of powder body material is placed on the tundish centre, motlten metal has on every side played the effect of heating to powder body material, improved the temperature of powder body material, make powder body material easier, improved the quality of reaction-injection moulding metal blank greatly with combining of metal.
(4) description of drawings:
Accompanying drawing 1 is the existing nozzle-integrated structural representation of blending formula.
Accompanying drawing 2 is the overall structure schematic diagram of the related a kind of composite reaction-injection moulding center blending formula nozzle of the present invention.
Wherein: 1 is the motlten metal tundish, and 1a is motlten metal tundish inlet, and 2 is the powder nozzle, 2a is the powder nozzle entrance, and 3 is plenum chamber, and 3a is the gas access, 4 for carrying the carrier pipe of adulterated powder material, and 4a is for carrying the inlet of adulterated powder material carrier pipe.
(5) specific embodiment:
Embodiment: a kind of composite reaction-injection moulding center blending formula nozzle (see figure 2), comprise plenum chamber 3 and tundish 1, it is characterized in that being provided with at tundish 1 center a carrier pipe 4 of carrying the adulterated powder material, the outlet of carrier pipe 4 is enclosed within the outlet of tundish 1 and the export department of carrier pipe 4 protrudes in the outlet of tundish 1.
The diameter of the carrier pipe 4 of above-mentioned said conveying adulterated powder material can be 8 millimeters.
The export department of above-mentioned said carrier pipe 4 protrudes in the outlet of tundish 1, and its projecting height can be at 7 millimeters.
Claims (3)
1, a kind of composite reaction-injection moulding center blending formula nozzle, comprise plenum chamber and tundish, it is characterized in that being provided with at the tundish center carrier pipe of carrying the adulterated powder material, the outlet of carrier pipe is enclosed within the outlet of tundish and the export department of carrier pipe protrudes in the outlet of tundish.
2, according to the said a kind of composite reaction-injection moulding center blending formula nozzle of claim 1, it is characterized in that the diameter of the carrier pipe of said conveying adulterated powder material can be the 3-8 millimeter.
