Abstract
An ejecting forming preparation device comprises a crucible (1), a stopping bar (2), an atomizing nozzle (3), a vacuum chamber (5), a powder bin (11), a molten drop collector and an over-ejected powder collecting port (10). The ejecting forming preparation device is characterized in that an air inlet (4) is arranged on one side of the atomizing nozzle (3), and an outlet of the powder bin (11) is arranged on the other side of the atomizing nozzle (3). The molten drop collector can be a pipe collector (7), a bar collector (8) or a plate collector (9). An included angle between the tangential direction and the vertical axis of an air outlet of the atomizing nozzle (3) ranges from 30 degrees to 60 degrees, and the internal shape of the atomizing nozzle (3) is Laval-shaped. The ejecting forming preparation device is capable of producing near-net-shaped particle-reinforced metal matrix composite parts or moulds which are uniform in sizes, shapes and thermodynamic conditions and the like and dense in structure, have rapid-solidification structural characteristics, and are formed of reinforcing particles and matrix materials which are combined excellently.
Description
Technical field
The present invention relates to a kind of device that is used for the reaction-injection moulding preparation, can guarantee refinement atomizing particle effectively, improve nebulization efficiency and save atomization gas.
Background technology
Osprey company adopts spray-up method to prepare particles reiforced metal-base composition, and its building mortion is as shown in Figure 2.Motlten metal is flowed down by crucible 12 bottom through-holes, and the high speed inert gas that is sprayed by nozzle 20 atomizes to it.Ceramic particle is blown in the metal drop atomizer (atomizing) cone by powder storehouse 14, mixes with metal drop, on receiver 17, deposits and solidifies.This manufacturing process has following shortcoming: the inert gas atomizer motlten metal is adopted in (1), because gas density is little, momentum is low, so the efficient of atomizing is very low, needs to consume a large amount of inert gases, and atomizing droplet size skewness; (2) ceramic particle can influence the flight path of atomizing molten drop, makes the deposit preform shape be difficult to control.
The Chinese patent ZL02237229.6 that authorized on May 14th, 2003 discloses the shaping nozzle of a kind of center spraying type, is used for reaction-injection moulding and prepares particles reiforced metal-base composition.Its structure such as as shown in Figure 4, by crucible 21, powder conveying pipe 22 is formed with high pressure nozzle 23.Its operation principle is: powder body material is by ejection in the powder conveying pipe 22, and the motlten metal in the crucible 21 is flowed out by the circumferential weld outlet of bottom, and the inertia gases at high pressure are acted directly on the motlten metal by outermost high pressure nozzle 23 ejections, make it atomizing.The shortcoming of this nozzle is: (1) powder delivery pipe diameter is less, and length is very big, and powder stops up in pipeline easily, influences enhanced granule in the inner even distribution of deposit preform; (2) because the powder conveying pipe passes the tundish bottom, it is big that the external diameter of mozzle 24 becomes, and makes the diameter of plenum chamber gas outlet become big, influences the nozzle atomization effect.
Summary of the invention
The technical problem that solves
For fear of the weak point of prior art, the present invention proposes a kind of device that is used for the reaction-injection moulding preparation, can guarantee refinement atomizing particle effectively, improves nebulization efficiency and saves atomization gas.And enhanced granule has better mechanics and high-temperature behavior.Its technical scheme is reliable, production cost is low, product quality is easy to control.
Technical scheme
A kind of device that is used for reaction-injection moulding preparation comprises crucible 1, ends logical rod 2, atomizer 3, vacuum chamber 5, powder storehouse 11, molten drop receiver and over-spray powder and collect mouthfuls 10; It is characterized in that: the side at atomizer 3 is provided with air intake 4, and opposite side is the outlet in powder storehouse 11.
Said molten drop receiver is tubing receiver 7, bar receiver 8 or plate receiver 9.
Said atomizer 3 gas outlet tangential directions and vertical axis are 30 °～60 ° angles, and the interior shape of atomizer 3 is the Laval type.
Beneficial effect
A kind of device that is used for the reaction-injection moulding preparation that the present invention proposes can be produced the particles reiforced metal-base composition parts or the mould that combine good near-net-shape in aspect homogenization rapid solidification tissue signature, compact structure and enhanced granule such as size, shape and thermodynamic conditions with matrix material.

The specific embodiment
Combine embodiment, accompanying drawing that the present invention is further described at present:
The device of present embodiment comprises crucible 1, ends and lead to rod 2, atomizer 3, vacuum chamber 5, powder storehouse 11, molten drop receiver and over-spray powder collection mouth 10; Side at atomizer 3 is provided with air intake 4, and opposite side is the outlet in powder storehouse 11.Said atomizer 3 gas outlet tangential directions and vertical axis are 30 °～60 ° angles, and the interior shape of atomizer 3 is the Laval type.
Said molten drop receiver is tubing receiver 7, bar receiver 8 or plate receiver 9.
Crucible 1 can be realized the fusing and the insulation of metal, and through hole is arranged at the bottom of crucible, and motlten metal is through under this channel flow.Atomizer 3 bottoms have a circle to concentrate to flow to center line, and are 10 °～50 ° angles with vertical axis.
This device can effectively improve nebulization efficiency, makes the average grain diameter of drop reduce, and the distributed area of particle diameter narrows down, and it is more even to strengthen the distribution of particle in matrix.
