Description
Technical field
The invention belongs to material forming field more particularly to a kind of antigravity casting suction pipes, increase especially suitable for particle
Strong aluminum matrix composite vacuum adjustable pressure casting.
Background technology
Particles reiforced metal-base composition has good specific strength, specific stiffness, elevated temperature strength, wearability, corrosion resistance
Equal comprehensive mechanical properties, are developed rapidly and apply.But the mobility of particles reiforced metal-base composition is poor, forming
Cast-internal easily forms the defects of stomata and shrinkage cavity shrinkage porosity in the process, and manufacturing process uses vacuum pressure regulation manufacturing process, is
One kind of antigravity casting.
Suction pipe is the important tool of material antigravity casting forming, and effect is that guiding aluminium alloy fills under pressure
Cavity.Suction pipe generally uses steel material, when use to need that coating is prepared on its surface, and prevents temperature flowing aluminium alloy to suction pipe
Corrosion.The process of suction pipe swabbing needs to heat, and consumes the energy, the labor intensity for clearing up suction pipe is also higher, in the process
Serious noise and dust are will produce, i.e., cannot meet the requirement of environmental protection, can also generate unfavorable shadow to the physical and mental health of operator
It rings.
The etching problem of suction pipe can be solved using ceramic suction pipe, but in the environment of alternating hot and cold, ceramic suction pipe is easy to
Cracking, service life is short, and cost is higher.
Invention content
Patent technology to be solved of the present invention is existed for particle enhanced aluminum-based composite material antigravity casting suction pipe
The problems such as inner wall corrosion during use, cleaning work is heavy, provides a kind of antigravity casting suction pipe.
Technical solution is used by patent of the present invention solves its technical problem：The present invention relates to a kind of antigravity casting use
Suction pipe, including：Liner (1), filler (2), housing (3), flange (4), upper weld seam (5), screw hole (6), packing slot (7), lower weldering
(8), back welding seam (9), liner (1) and flange (4) are stitched by upper weld seam (5) connection, housing (3) and flange (4) pass through lower weld seam
(8) it connects, liner (1) and housing (3) are connected by back welding seam (9), and filler (2) is swollen using high-melting-point low-heat and heat conduction is good
Adverse reaction does not occur with aluminium alloy for material, liner (1) material, and housing (3) material may be used and the identical material of liner (1)
Material, can also be used common heat resisting steel, packing slot (7) and symmetrical two screw holes (6) is opened up on flange (4), which makes
With artificial prepares coating and the process of cleaning can be simplified in the process.
The present invention has the following advantages that compared with prior art：
Common heat resisting steel tubing or plank welding forming may be used in the housing (3) of suction pipe involved in the present invention, also may be used
With using the identical material with liner (1)；
The liner (1) of suction pipe involved in the present invention uses high-melting-point and the material of adverse reaction does not occur with aluminium alloy, can
To reduce the content of harmful element in aluminium alloy, improve material property；
Suction pipe involved in the present invention is full of filler (2) between housing (3) and liner (1), and filler (2) uses Gao Rong
The point material that low-heat is swollen and heat conduction is good can be greatly reduced housing (3) and liner (1) is straight under the premise of ensureing good heat transfer
Connect difficulty of processing when cooperation.
Suction pipe involved in the present invention does not need prepares coating using its preceding inner wall, without cleaning after use, can reduce
Energy consumption simplifies the process of manual cleaning suction pipe.
