Loose boss 2 is arranged one group, and the number of every group of locking boss is 4~6.Respectively it is arranged 1~2 group in the two sides of locking boss 2
Locking convex block 3, the number of every group of locking convex block 3 are 25~50.The utility model in specific implement, locking boss 2
Height is greater than the height of locking convex block 3.
Further, annular groove 4 is set in the two sides of locking convex block 3.
The steel bushing of the utility model is provided with anti-loose structure, and the locking convex block and locking boss being arranged in anti-loose structure can
Staggered dentation coupling structure is formed between aluminum alloy part and steel bushing after making moulding by casting, is improved linking intensity, is prevented steel
Set loosens.
Be directed to above-mentioned steel bushing, the technique for also accordingly devising castingin steel bushing in a kind of aluminum alloy part, the technique be by
The steel bushing castingin of above-mentioned setting anti-loose structure is into aluminum alloy part.Steel bushing and castingin can be ensured in aluminium alloy by the technique
Linking intensity when in part, between steel bushing and aluminum alloy part.The technique specifically includes the following steps:
1, by drawing machining production steel bushing.
2, steel bushing oil removing is derusted pretreatment.
3, by steel bushing outer surface coating coating processing.In the step, it may be preferable that coating is metallic nickel and metallic silver.Metal
The thickness of coating of nickel is 10 μm, and the thickness of coating of metallic silver is 8 μm.
4, steel bushing is preheated.The process that steel bushing preheats in the step is as follows, and steel bushing is put into holding furnace and is heated to 80
DEG C~100 DEG C, and keep the temperature until use finishes.
5, by steel bushing leaching molten aluminum processing.The concrete operations of the step are as follows, and steel bushing is put into molten aluminum and impregnates 140~160
It is taken out after second.
The temperature of molten aluminum is 700 DEG C~720 DEG C in step 5.
6, steel bushing is put into mold and accurate positioning.
7, lower sand core, molding are poured aluminum alloy part.
Using the aluminum alloy part for the castingin steel bushing that above-mentioned technique manufactures, there is good structural strength, especially aluminium to close
Golden part has good linking intensity with steel bushing part.
In above-mentioned technique, provided with the treatment process for carrying out coating coating in steel bushing outer surface, metal is particularly coated
Nickel and metallic silver, the utility model passes through the thickness of coating for limiting metallic nickel and metallic silver, under the thickness of coating, after capable of making
The effect of continuous leaching molten aluminum is improved, so that it is guaranteed that steel bushing and aluminum alloy part couple shaping strength.
In above-mentioned technique before placing steel bushing and entering mold, steel bushing is carried out to preheat-soak aluminium processing, first preheating insulation improves
The temperature of steel bushing, steel bushing occurs biggish heat expansion deformation and influences to couple strong when preventing from impregnating molten aluminum and subsequent casting molten aluminum
Degree.The steel bushing of preheating insulation is immersed in molten aluminum and is impregnated, and can promote the binder course of steel bushing and aluminium alloy in subsequent casting molten aluminum
Form and improve the intensity of binder course.
The steel bushing used in the utility model is provided with the anti-loose structure formed by locking boss and locking convex block, due to
The setting of anti-loose structure greatly increases the curved surface on steel bushing surface, especially the biggish curved surface of curvature, therefore, closes in cast aluminum
When golden liquid, binder course a possibility that having biggish generation stress formed at the curved surface on steel bushing surface, however, in castingin work
The technique that preheating insulation is devised in skill is also played and is mentioned in conjunction with the generation of ply stress when preventing casting by preheating insulation
The effect of high binder course intensity.
The above-mentioned technique of preheating in to(for) steel bushing is therefore can also to play rush after coating the coat of metal to steel bushing
The effect of binder course is formed in conjunction with molten aluminum into the coat of metal.
It first preheats, is and to avoid cold part and molten aluminum excessive temperature differentials to remove steel bushing surface moisture, quick-fried spray occurs when soaking aluminium
It is dangerous.
The principle of leaching aluminium is that aluminium generates metallurgical reaction, phase with coating silver under 700 DEG C~720 DEG C hot conditions first
Mutually fusion；It is external after being poured simultaneously to be integrated with aluminum alloy melt fusion, it is to guarantee steel bushing to realize the over effect of leaching aluminium layer
The important step being combined as a whole with molten aluminum.
