Abstract
The present invention relates to apparatus for making aluminum clad steel wire, and is especially one novel steel wire clad device with symmetric through hole. The cladding cavity has one through hole, one blank leader mounted inside the through hole, and one leading mold and one cladding mold separately on two sides of the blank leader. Adopting the blank leader can ensure the concentricity between the clad steel wire and the cladding aluminum layer, and the symmetric hole structure allows increased interval between the leading mold and the cladding mold to ensure tight cladding of the aluminum layer onto the steel wire. In addition, the present invention facilitates the machine of the mold.
Description
Technical field:
The present invention relates to the aluminum cald steel wire manufacturing equipment.
Background technology:
A kind of continuously extruded principle that illustrates among European patent EP-A-071490, continuous extruder comprises a rotation squeegee roller that has the circumferencial direction race, the squeegee roller groove relies on the effect of frictional force to drive blank forward, when running into material blocking block, blank enters charging aperture, squeezes out needed product by the mould of installing below charging aperture.Aluminum cald steel wire all is to adopt continuous coating technology to produce now, coating die cavity is that a core blank that coats continuously imports part, this blank imports the quality that part has not only determined coated prod, also because this blank imports the core frock that part is continuous coating, its manufacturing cost will influence the aluminum cald steel wire production cost of products.Existing coating cavity and mould assembling are as shown in Figure 1.This structural disadvantages is as follows: because the technical difficulty in the design, make mould up and down the blank of both sides flow and be difficult to equilibrium, cause aluminum cald steel wire very easily to occur eccentric and the coating of high conductivity product not tight, cause product defective.The difficult processing of die cavity processing difficulties and die cavity simultaneously, can't be checked its machining accuracy after machining to guarantee design accuracy, makes the processing of cavity die cavity have very big randomness, be difficult to ensure the quality of products, and the processing cost height.When off-centre takes place coated prod, be difficult to revise the machining shape of cavity die cavity.
Summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, a kind of novel symmetrical through hole aluminum cald steel wire coating unit is provided, cavity die cavity handling ease guarantees machining accuracy, and coating thickness evenly and avoid steel wire off-centre.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of novel symmetrical through hole aluminum cald steel wire coating unit, a through hole is arranged in the coating cavity, adorn a blank in the through hole and import part, the both sides of blank importing part are equipped with guiding mould and coating mould respectively.
Described blank imports the part center and has looping pit, and looping pit is communicated with the symmetrical holes that blank imports on the part.
Described symmetrical holes can be an Any shape.
Described blank imports part and guiding mould or coating mould one.
The angle β of the center line of charging hole is 30 °-120 ° on described symmetrical holes and the cavity.
Blank of the present invention imports symmetrical holes on the part to guarantee in looping pit up and down and left and right sides blank flows symmetrically fully, has thoroughly eradicated the problem of aluminum cald steel wire coated prod steel wire and aluminium lamination off-centre.The coating gap that symmetrical holes structure of the present invention allows to lead between mould and the coating mould amplifies, and it is tight to guarantee that high conductivity aluminum cald steel wire aluminium lamination coats.The die cavity of thoroughly having eliminated cavity makes that cavity processing is extremely easy.Because this invention makes guiding mould and coating mould structure be reduced to cylindrical shape by original conical surface profile, makes the mould manufacturing be more prone to.
Description of drawings:
Fig. 1 (a) is a conventional bag coating device structural representation, and Fig. 2 (b) is the A-A schematic diagram.
Fig. 2 (a) is a structural representation of the present invention, and Fig. 2 (b) is the B-B schematic diagram.
The specific embodiment:
A kind of as shown in Figure 2 novel symmetrical through hole aluminum cald steel wire coating unit, a through hole is arranged in the coating cavity 1, adorn a blank in the through hole and import part 2, blank imports the part center and has looping pit 4, looping pit is communicated with the symmetrical holes 3 that blank imports on the part, and symmetrical holes can be an Any shape, and the angle β of the center line of charging hole 7 is 90 ° on symmetrical holes and the cavity, the both sides of blank importing part are equipped with guiding mould 5 and coating mould 6 respectively, and annular imports part and is manufactured on the guiding mould.
Adopt a kind of novel symmetrical through hole aluminum cald steel wire coating unit shown in Figure 2,1 process-cycle of coating cavity has shortened 6 days, decrease machining cost 22%.It is 40% that this cavity is applied to make conductance, coat that back product external diameter is 6.50, steel wire diameter is 4.05 aluminum cald steel wire, makes offset be reduced to 0.16mm from the 0.61mm of original cavity.The lamination of reversing that does not tightly cause also no longer takes place to coat in coated prod.The fuse of the carbide alloy of inlaying of mould is all unified, and manufacturing cost descends 17%.
