Description
Technical field
This utility model relates to hot-working-casting field, particularly relates to a kind of bimetallic eccentric centrifugal cast structure.
Background technology
The technical process of existing bimetallic (steel backing copper bush) centrifugal casting:
Prepare steel bushing, base plate, cover plate → be welded on steel bushing by base plate → steel bushing, base plate, cover plate are cleaned the upper protection of rust cleaning
Layer → load onto centrifugal casting machine toward the cover plate → heating steel bushing melting copper material → steel bushing that feeds → burn-on in steel bushing, rotation, cool down.
Existing bimetallic (steel backing copper bush) centrifugal casting, when producing high trade mark copper alloy (such as: ZCuPb20Sn5), main
There are three big shortcomings: (1) steel is bad with copper Coating combination, is easily generated lamination, and particularly bimetallic internal diameter diameter is more than
The when of more than 80mm, produce lamination clearly；(2) it is easily generated component segregation；(3) product be easily generated crackle (laterally and
Longitudinally), in its production process, percent defective is high, and the qualification rate of product is extremely low.
Summary of the invention
This utility model provides bimetallic eccentric centrifugal cast structure, it is therefore an objective to solve prior art problem, it is provided that a kind of
Copper material is the tightst with the combination of steel bushing, and the copper material interior tissue after fusing is tight, is not likely to produce the bimetallic of various defect
Eccentric centrifugal cast structure.
The technical solution adopted in the utility model:
Bimetallic eccentric centrifugal cast structure, it is characterised in that: having main body, main body is by steel body, overcoat, end cap and copper material
Composition, the external overcoat that is arranged with of steel, the two ends of overcoat are connected by end cap respectively with the two ends of steel body, steel body, overcoat and two ends
End cap surround an airtight gap, in gap fill copper material, the outward flange of centrifugal casting machine is provided with frock, and frock is big
The semiclosed set that little, shape matches with main body, main body is placed in the semiclosed set of frock.
Described end cap welds with between steel body and overcoat respectively.
Described frock is that angle steel is welded to form with centrifugal casting machine.
The opening of described frock is embedded with fixed block, and main body is limited in inside frock by fixed block.
The beneficial effects of the utility model: product installation site is in the edge of centrifugal casting machine, produce the most centrifugal
Power so that copper material is the tightst with the combination of steel body, and the copper material interior tissue after fusing is tight, is not likely to produce various defect.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model main body；
Fig. 2 is this utility model centrifugal casting machine structural representation operationally.
In figure: 1. main body；2. steel body；3. overcoat；4. end cap；5. copper material；6. centrifugal casting machine；7. frock；8, fixed block.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Bimetallic eccentric centrifugal cast structure as shown in Figure 1 and Figure 2, has main body 1, and main body 1 is by steel body 2, overcoat 3, end cap
4 and copper material 5 form, be arranged with overcoat 3 outside steel body 2, the two ends of overcoat 3 are connected by end cap 4 respectively with the two ends of steel body 2, steel
The end cap 4 at body 2, overcoat 3 and two ends surrounds an airtight gap, fills copper material 5, the outward flange of centrifugal casting machine 6 in gap
Being provided with frock 7, described frock 7 is welded to form with centrifugal casting machine 6 for angle steel, and frock 7 is that size, shape match with main body 1
Semiclosed set, main body 1 is placed in the semiclosed set of frock 7, and the opening of described frock 7 is embedded with fixed block 8, fixed block 8
Main body is limited in inside frock, prevents main body 1 from dropping out outside frock 7 when centrifugal casting.
Described end cap 4 welds with between steel body 2 and overcoat 3 respectively.
Product installation site is in the edge of centrifugal casting machine, produces bigger centrifugal force so that copper material and the knot of steel body
Close the tightst, and the copper material interior tissue after fusing is tight, is not likely to produce various defect.
In the course of the work, first each parts to main body eliminate rust, clean, the process of up-protective layer, after having processed,
By filling full copper material 5 in the gap between steel body 2 and overcoat 3, end cap 4 is welded with steel body 2 and overcoat 3 respectively, gap is close
Feng Chengyi airtight space, and steel body 2 and overcoat 3 are heated until copper material 5 melts completely, then copper material 5 is melted completely
The main body 1 changed is placed in the frock 7 on centrifugal casting machine 6, rotates centrifugal casting machine 6, to completing centrifugal casting, by centrifugal casting
The semi-finished product lathe completed is processed to figure paper size, i.e. completes the production of foundry goods.
