Description
Technical field
The utility model belongs to technical field of mold, is related to a kind of mould, is used to improve copper more particularly, to one kind
The mould of line surface quality.
Background technology
Copper cash is the important conductor material of all kinds of winding wires such as enamel-covered wire, lapped insulation line, and it has, and conductance is high, machinery
The advantages that performance is good.But in actual production, copper line surface oxidation is an important factor for reducing product quality, particularly to exist
In drawing process, copper product is deformed by mould, substantial amounts of to deform the oxidation of thermal acceleration copper line surface.How copper cash table is reduced
Face aoxidizes, and especially reduces the oxidation occurred in pulling process, significant.
Utility model content
To solve the above problems, the utility model aims to provide a kind of mould for being used to improve copper line surface quality.
According to one side of the present utility model, a kind of mould for being used to improve copper line surface quality, the mould is included gradually
Diameter reducing area, setting zone, outlet area and multiple shaped form cooling ducts are deformed, wherein, the inner of the gradual change shape diameter reducing area and institute
The one end for stating setting zone is connected, and the other end of the setting zone is connected with the inner of the outlet area, and the multiple shaped form is cold
But passage is evenly distributed on around the gradual change shape diameter reducing area, the setting zone and the outlet area.
According to exemplary embodiment of the present utility model, the gradual change shape diameter reducing area is in the radial section vertical with axis
First is circular, and the described first circular diameter is from the outer end of the gradual change shape diameter reducing area to the inner of the gradual change shape diameter reducing area
It is nonlinear on direction to be gradually reduced.
According to exemplary embodiment of the present utility model, the setting zone is in the radial section vertical with axis in the second circle
Shape.
According to exemplary embodiment of the present utility model, the outlet area is in the radial section vertical with axis in the 3rd circle
Shape, the described 3rd circular diameter are nonlinear gradual on the inner outer extreme direction to the outlet area from the outlet area
Increase.
According to exemplary embodiment of the present utility model, the outer end of the gradual change shape diameter reducing area is handled using fillet.
According to exemplary embodiment of the present utility model, the outer end of the outlet area is handled using fillet.
Compared with prior art, according to the mould of the present utility model for being used to improve copper line surface quality, copper can be accelerated
Line distributes in the heat of forming process, improves copper line surface quality, avoids copper cash from aoxidizing, and ensures cross sectional shape, improves the mould longevity
Life.
Brief description of the drawings
Fig. 1 is according to the diagrammatic cross-section of the present utility model for being used to improve the mould of copper line surface quality.
In figure, 1- gradual change shapes diameter reducing area, 2- setting zones, 3- shaped forms cooling duct, 4- outlet areas.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of mould for being used to improve copper line surface quality, its structure is as shown in figure 1, the mould gradual change shape diameter reducing area 1
Radial section (section vertical with mold axis) be shaped as circle, from right-hand member, terminal type non-linear is gradually reduced its diameter to the left,
So as to which the side of gradual change shape diameter reducing area 1 is in the circular arc of indent, the low order end of gradual change shape diameter reducing area 1 is handled using fillet.
The radial cross-sectional shape of the setting zone 2 is circle, the right-hand member radial section of setting zone 2 and gradual change shape diameter reducing area
The diameter of 1 left end radial section is equal, so that the right-hand member of setting zone 2 and left end (the gradual change shape tube reducing of gradual change shape diameter reducing area 1
The inner in area 1) it is in smoothing junction.
The radial cross-sectional shape of the outlet area 4 is circle, and from right-hand member, terminal type non-linear gradually increases its diameter to the left, so as to
The side of outlet area 4 is in the circular arc of indent.The diameter of the right-hand member radial section of outlet area 4 and the left end radial section of setting zone 2
Equal, so that the left end of the right-hand member (the inner of outlet area 4) of outlet area 4 and setting zone 2 is in smoothing junction, outlet area 4 is most left
End is handled using fillet.
The shaped form cooling duct 3 shares 16, and it is evenly distributed on gradual change shape along mold center's axis in array-like
Around diameter reducing area 1, setting zone 2 and outlet area 4, cooling medium passes therethrough.
Specifically, the mould at work, in the state of cooling medium is by cooling duct 3, circular cross-section copper cash
Enter from the right-hand member of gradual change shape diameter reducing area 1, by gradual change shape diameter reducing area 1, gradually deformation, and pass through a left side for gradual change shape diameter reducing area 1
End, into setting zone 2, reaches final molding by outlet area 4.
Above-described embodiment, the purpose of this utility model, technical scheme and beneficial effect are entered
One step describes in detail, should be understood that and the foregoing is only specific embodiment of the present utility model, is not used to limit
Determine the scope of protection of the utility model, it is all within the spirit and principles of the utility model, any modification for being made, equally replace
Change, improve, should be included within the scope of protection of the utility model.
