Description
Technical field
The present invention relates to the manufacturing field that injection prepares composite material, more particularly to a kind of can improve to spray shaping multiple tube
The device of the bond strength of base and corresponding application process.
Background technology
At present, injection shaping is a kind of new technology that special material is prepared using the method quickly solidified, which has concurrently
There are the dual characteristics of nearly end form processing and semi-solid processing.High-pressure inert gas will be from tundish in injection shaping atomizer
The interior alloy liquid stream by catheter outflow is atomized into tiny molten drop, and molten drop flies and gradual under the action of high-speed flow
Cooling, is deposited on the effigurate depositor of tool before these molten drops not yet solidify completely, is penetrated by varying molten drop
Stream and the relative position of depositor and the forms of motion of depositor, can obtain the different shapes such as disk (column), pipe (ring), plate (band)
Semi-finished product blank.
Traditional pipe manufacturing technology can produce seamless tube blank, it can be difficult to production composite pipe blank base, even if to produce
And difficulty is bigger.Therefore the technology of some existing production composite pipe blank bases utilizes the mode of injection shaping mostly.
Chinese patent CN200410022954.9-《Jet deposition prepares the method and its equipment of large ring》Disclose one
The method that kind jet deposition prepares large ring, grains will be formed using inert gas by molten metal or alloy atomization,
Inject directly on matrix, through hitting, coalescing, solidifying and form deposit preform, and the movement of crucible and atomizer and the rotation of matrix
Turn, elevating movement by intelligent control, matrix using interior hot method heating, it is characterized in that:The molten metal degree of superheat for 150 DEG C~
350 DEG C, jetting height is 100~300mm, and atomization air pressure is 0.8~1.2MPa, a diameter of 3.0~6.0mm of liquid stream, and matrix turns
Speed is 1~10rpm, and crucible movement rate is 5~20mm/s, and matrix lifting speed is 0.1~1.0mm/min.Wood invention also public affairs
Equipment used by this method is opened.The invention is that a kind of preparation for large ring will not produce the injection that breaks of cracking and sink
The method that product prepares large ring.
Contrasted by field conduct, the tissue that major advantage is to control different radial positions of this method can
System respectively goes out the larger pipe of wall thickness.But it also has the shortcomings that obvious：
Matrix, deposit preform and substrate support seat etc. need to move along a straight line back and forth during preparation.Due to deposition blank and
The part quality moved together is big, causes inertia very big, it is difficult to controls, so as to constrain size and the quality rule of deposition pipe
Mould, while cause shuttle speed quickly, can not possibly also constrain the cooling rate of deposit preform, it can only be produced necessarily furthermore with the technique
The composite pipe blank base of length, and pipe is installed and fetches and delivers inconvenience, limits the development of the technique.
103962558 A of patent CN disclose it is a kind of prepare horizontal pipe bad supporting mechanism and atomization system, molten steel is melted
Tundish is poured into after change, when molten metal flows through nozzle by the catheter of tundish bottom, the high pressure sprayed in nozzle is high
Fast inert gas atomizer forms an atomizer (atomizing) cone, atomizing particle is deposited on the pipe matrix of lower section, pipe into tiny particle
Matrix moves forward under the drive of supporting mechanism while rotating；Pipe matrix is before atomizer (atomizing) cone of entering through high-frequency induction
Coil quickly heats up to 800 DEG C or so, can effectively strengthen the combination power for spraying layer and pipe matrix.When pipe deposition finishes it
Equipment is slowly removed under the drive of supporting mechanism afterwards, follow-up pipe follows up at the same time, carries out continuous production, ultimately forms compound
Pipe base.
The starting stage that this technique is shaped in injection, since molten steel flows through tundish and catheter, temperature substantially reduces,
Liquid phase ratio substantially reduces in the metallic particles formed after atomization, and result in after complex matrix collides is difficult often to be incorporated in one
Rise, so as to form the source of cracking.
In addition, high change after the previous emperor is presented in the temperature of casting steel stream at initial stage, the temperature of initial steel stream is relatively low, in atomization and
Temperature is lower during deposition, it is difficult to effectively realize the bonding with complex matrix.
In conclusion shaping production composite pipe blank base using injection under the prior art remains various shortcomings, therefore these are lacked
The improvement of point seems even more important for preparing composite pipe blank base for injection.
