Background technology
Tangential continuous extruder comprises squeegee roller, boots seat and is installed in mould on the boots seat, and at present tangential continuous extruder can only be used for producing the aluminum-clad steel wire that is used for carrying cable or the sheath on coaxial cable or cable and the optical fiber.
The aluminum-cladding copper pipe material is a kind of tubing that is used for air-condition heat exchanger and some heat exchangers, this tubing can solve copper pipe and aluminium in the air-condition heat exchanger and stick up in electrochemical corrosion problem between the sheet or the heat exchanger corrosion resistance problem in the pipe, and therefore this tubing is received by the market very much.The production technology of aluminum current copper-clad tubing is to utilize in advance the round copper bar of cast and the round aluminum pipe edge of cast in advance to overlap, and is rolled into pipe with planetary rolling then, and then operations such as drawing, finishing, annealing, makes aluminum-cladding copper pipe at last.There is following deficiency in this production method:
1, because the core bar limited length of milling train, so the product length that rolls out is restricted;
2, since copper alloy (comprising brass, copper-nickel alloy, bronze etc.) bar on such planetary rolling, product cracking, oxidation etc. can occur when rolling and can not form product, so more be rolled into bimetallic tubing on this planetary rolling again behind copper alloy bar and the aluminum pipe edge cover, so its internal layer material of such tubing is confined to red copper, outer tubing is confined to fine aluminium or 3003 materials;
3, because the inner materials of this aluminum-cladding copper pipe can only be a red copper, so this series products can not be suitable for and be restricted for the occasion that interior media belongs to various strong corrosive medias;
4, the rolling aluminum-cladding copper pipe that comes out because two will cut out, is wasted very big.
Therefore how to improve the quality of aluminum-cladding copper pipe material, the raw material variety that makes it to be suitable for is more extensive, thereby satisfy higher performance requirement, and effectively to save material be present problem demanding prompt solution.
The utility model content
The purpose of this utility model is to provide a kind of can produce, be applicable to all kinds of copper material aluminiums, good product quality and the tangential continuous extruder that is used to produce aluminum-cladding copper pipe that can save material continuously.
This tangential continuous extruder that is used to produce aluminum-cladding copper pipe that the utility model provides, comprise boots seat and the extrusion die that is installed on this boots seat, this comprises die holder and core rod to it is characterized in that described extrusion die, has the aluminium inlet port on the die holder, core rod is arranged in die holder, core rod comprises and has the current divider of shunting pawl, guide pipe, cladding mode, the axial retention bolt, current divider is nonrotatably mounted tO in the die holder, the axial location of its shunting pawl is corresponding to the aluminium inlet port, cladding mode holds out against by the shunting pawl of axial retention bolt and current divider, guide pipe is arranged in current divider, and with cladding mode an axial spacing is arranged.
In order to make copper pipe and aluminium strong bonded, described boots seat bottom is provided with heating member.
Stable for cladding mode is felt relieved, and aluminium can better be shunted, described cladding mode is a taper seat with the contact-making surface of shunting pawl.Described shunting pawl is by 2-4.The taper seat that cladding mode contacts with the shunting pawl, its coning angle is 90 °.
In order to reduce the frictional force of copper pipe centering generation, the inner chamber of cladding mode is a copper pipe centering end at the end near guide pipe, and the length of this centering end is 0.25-0.5 times of copper pipe external diameter.
Described cladding mode is with an overcoat, and between cladding mode and the axial retention bolt grommet is arranged.
The utility model is improved existing tangential continuous extruder, especially boots seat and extrusion die have been carried out design again, aluminum-cladding copper pipe can be made continuously, solved and made the serial problem that aluminum-cladding copper pipe exists with milling method at present, improved the quality of aluminum-cladding copper pipe on the one hand, make aluminium coat evenly firmly, and the kind of aluminum-cladding copper pipe is corresponding to be increased, its copper pipe material can be used brass, copper-nickel alloy and alloyed copper, aluminium can be used fine aluminium and alloy aluminum, make the scope of application of aluminum-cladding copper pipe wider, produce continuously on the other hand and saved raw material, reduced cost.
