Description
Technical field
The utility model is related to extrusion die technical fields, more particularly to a kind of extrusion die for big square of extruded threads
Tool.
Background technology
In the prior art, the yield strength of big specification squares lead is larger, in the practical coiling of enamelled winding wire, big specification
Squares lead is wound with bigger difficulty, when being primarily present coiling small-bend radius, since the surrender of big specification squares lead is strong
Spend larger, magnet wire insulation surface layer machinery cracking, conductor deformation warps, and the galling of insulation paint film is pulled, and coiling finished product is shapeless etc.
More basic quality problems, although can realize the enameled wire for producing small yield strength in the prior art, processing technology needs
Two procedures, the production cost increases, and using the conducting wire after annealing process processing, and conductor internal stress substantially eliminates, and surrenders
Intensity is less than normal.
Utility model content
Technical problem to be solved in the utility model is the yield strength of big specification squares lead, overcomes the prior art
Disadvantage provides a kind of extrusion die for big square of extruded threads,
In order to solve the above technical problems, the utility model provides a kind of extrusion die for big square of extruded threads, packet
Including mold core, the mold core includes being smoothly connected successively and coaxial inlet region, sizing area and outlet area from feeding mouth to discharge port,
The inlet region and outlet area be in it is horn-like, the sizing area be it is cylindric, and the internal diameter of the inlet region by feeding mouth extremely
Discharge port direction is gradually reduced, and the internal diameter of the outlet area is gradually increased by feeding mouth to discharge port direction, it is characterised in that：Institute
The angle stated between inlet region one end and mold core far from sizing area is 150~160 °；
The sizing area is horizontally disposed；
Angle between the outlet area one end and mold core far from sizing area is 160 °.
The technical solution that the utility model further limits is：
Further, the angle between one end and mold core far from sizing area of the inlet region is 160 °.
The horizontal length of a kind of preceding extrusion die for big square of extruded threads, the inlet region is 3mm, described
Sizing area horizontal length is 4.5mm, and the horizontal length of the outlet area is 9.5mm.
A kind of preceding extrusion die for big square of extruded threads, the mold core are wolfram steel mold base.
The utility model has the beneficial effects that：
（1）In line cable industry, yield strength is mainly partial to the case hardness of line, in extrusion process of production, cavity
Inlet copper material is squeezed degree maximum, while the hardness of copper material is maximum, rear to flow into cavity, is squeezed out by mold, this practicality
It is novel that the one end of inlet region far from sizing area and the angle between mold core are increased to 150~160 °, storing area can be made to increase,
In inlet region in the case of identical storing amount, the horizontal length of storing area can be shortened, so as to so that the length of sizing area increases
Greatly, increase time for growing up of copper crystal lattice body, to realize the conducting wire of low yield strength, in addition, inlet region far from sizing area one
Angle between end and mold core is increased to 150~160 °, and the flow-guiding mouth between inlet region and sizing area can be made to increase, make copper material
Sizing area is more smoothly entered, in addition, the one end of outlet area far from sizing area and the angle between mold core are increased to 170 °,
The chamfering between sizing area and outlet area can be increased, make smoothly to be discharged by the conducting wire of sizing area；
（2）Since the one end of inlet region far from sizing area and the angle between mold core are increased to 150~160 °, by inlet region
Horizontal length be set as 3mm and can meet the storing amount of inlet region, and the horizontal length of sizing area can increase to 4.1~
4.7mm can greatly increase the time that copper crystal lattice body is grown up, to realize the conducting wire of low yield strength.
（3）The mold core of the utility model is made of wolfram steel mold base, and abrasion resistance properties are preferable, in addition, its lubricity compared with
Height can slow down resistance of the conducting wire by sizing area.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Wherein：1, mold core；2, inlet region；3, sizing area；4, outlet area.
Specific implementation mode
A kind of extrusion die for big square of extruded threads provided in this embodiment, structure are as shown in Figure 1.
This is used for the extrusion die of big square of extruded threads, including mold core 1, and mold core 1 is wolfram steel mold base, and mold core 1 is from feeding mouth
Include being smoothly connected successively and coaxial inlet region 2, sizing area 3 and outlet area 4, inlet region 2 and outlet area 4 are in discharge port
Horn-like, sizing area 3 is cylindric, and the internal diameter of inlet region 2 is gradually reduced by feeding mouth to discharge port direction, outlet area 4
Internal diameter is gradually increased by feeding mouth to discharge port direction.
Wherein, the angle between one end and mold core far from sizing area 3 of inlet region 2 is 150~160 °, makes inlet region 2
Storing amount increases, and the horizontal length of inlet region 2 is 3mm, the angle choosing between inlet region 2 one end and mold core far from sizing area 3
It is 160 °.
Sizing area 3 is horizontally disposed, and horizontal length is 4.1~4.7mm, and 3 horizontal length of sizing area is chosen as 4.5mm, increases
The time that copper crystal lattice body is grown up, to realize the conducting wire of low yield strength.
Angle between outlet area 4 one end and mold core far from sizing area 3 is 170 °, horizontal length 9.5mm.
In addition to the implementation, the utility model can also have other embodiment；It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection domain of the requires of the utility model is all fallen within.
