Description
Technical field
The present invention relates to wire electrode fields more particularly to a kind of high-efficiency rinsing wire electrode and preparation method thereof.
Background technology
In recent years, with the fast development of Chinese manufacturing, numerical control low-speed wire cutting Wire-cut Electrical Discharge Machining is excellent because of its
Processing performance and be more and more widely used.However, ordinary electrode silk is processing some complicated, special-shaped, hanging or high thickness
Spend workpiece when show it is unsatisfactory, such as：Aero-turbine nickel-base alloy, medical domain manufacture of intraocular implantation material titanium
Alloy, heavy type load outfit special high thick large gear or automobile industry abnormal shape covering punch die etc..Such workpiece is usual
It is complex-shaped, up and down it is hanging, drop is big, with certain taper, and be high hardness alloy or heat-resisting material etc., so as to cause work
Make the reduction of liquid flushing effect, when Wire EDM generates substantial amounts of heat and can not in time be taken away by working solution, this not only can
Cutting efficiency is reduced, and excessive thermal losses can be made on wire electrode wire electrode to be caused to be blown due to overheat.Ordinary electrode
Wire material especially holds when special-shaped high hardness alloy or high temperature resistant superalloy materials are cut under above this complex working conditions
Easy fracture of wire, and cutting efficiency is low.
The content of the invention
First technical problem to be solved by this invention is to provide a kind of cutting efficiency high height for the prior art
Effect rinses wire electrode.
Second technical problem to be solved by this invention is to provide a kind of fracture of wire frequency low height for the prior art
Effect rinses wire electrode.
3rd technical problem to be solved by this invention be for the prior art and a kind of simple production process is provided, can
The preparation method of the above-mentioned high-efficiency rinsing wire electrode of strong operability.
Technical solution is used by the present invention solves above-mentioned first, second technical problem：A kind of high-efficiency rinsing electrode
Silk, including core, which is characterized in that the surface of the core has the strip projected parts extended along its surface, between each strip projected parts
Every setting, and the root edge of each strip projected parts diffuses in core and forms raised brim；The quality percentage of copper in above-mentioned core
Number content is 58.5~67.5wt%, and surplus is zinc and inevitable impurity, and the mass percent of the inevitable impurity contains
Amount is less than or equal to 0.5wt%；The mass percent content of zinc is 57.8~69.8wt% in above-mentioned strip projected parts, surplus for copper and
Inevitable impurity, and the mass percent content of the inevitable impurity is less than or equal to 0.3wt%.
In said program, copper content is the core material of 58.5~67.5wt%, with good tensile strength and enough
Plasticity and toughness.Because in EDM process, wire electrode must can bear certain tension and be impacted caused by electric discharge
Power if the strength of materials is too low or fracture toughness is too low, can cause wire electrode to shake, and ultimately result in cutting workpiece rough surface
Injustice in addition can cause multiple tracks cut stria, especially for unmanageable metal works, such as high rigidity under some vacant states
Material and high temperature resistant superalloy materials etc., the tension (intensity of composition electrode wire material) that when cutting applies is bigger, easier
Cutting, similary plasticity and toughness are better, are less susceptible to fracture of wire.Preferably, copper content is 61.5~64.5wt%, 61.5~
The copper content of 64.5wt% additionally aids wire electrode and recovers straight degree, helps to wear silk and the good electrode wire material pair of toughness
It is also beneficial to carry out Taper cutting processing.Zn content is the strip projected parts of 57.8~69.8wt%, and gasification performance is very good, special
Be not conducive to improve cutting efficiency.Since Zn content is relatively high in strip projected parts, zinc after a large amount of gasifications can be putting in cutting
The energy that electricity generates takes cutting metallic surface to, and improves flushing effect, while air pressure caused by zinc gasification can also be putting
The erosion object that electricity generates is blown away, and is created better environment for next pulse electric discharge, is conducive to process velocity.Therefore strip projected parts zinc
Content is higher, and cutting effect is better, but if Zn content is excessively high, can cause that fusing point is relatively low, enthalpy of vaporization reduces, be unfavorable for instead
Improve processing efficiency.However, according to copper zinc binary phase diagraml, Zn content has γ phase constitution structures for 57.8~69.8wt%, because
Harder and crisp for γ phase constitutions, processing performance is poor, then by setting raised brim that can increase strip projected parts and core knot
With joint efforts, picking caused by coming off due to protrusion is effectively prevented.In addition, Zn content has β for 43.5~53.5wt% raised brims
Phase constitution, the phase constitution electric conductivity is good, can effectively transfer discharge energy, so as to improve electric discharge cutting efficiency.

The premise that cutting is stablized in cutting must assure that in cutting process not fracture of wire first, and fracture of wire probability size mainly with wire electrode from
The correlations such as body heat dissipation performance, the state of cooling and chip removal performance.Strip projected parts structure provided by the invention can significantly increase silk material table
Area so that in the unit interval, wire electrode itself dispersed heat is dramatically increased, so as to avoid excessive thermal losses in electrode
On silk, wire electrode is caused to be blown due to overheat.When hanging workpiece up and down, working solution bath insufficient pressure, after cutting
Cutting workpiece surface is covered with the even powdered ablation product of gluing, this is mainly in discharge channel 10000
DEG C or more high temperature, working media, which will decompose, to be generated substantial amounts of high-molecular compound and reacts generation colloid with metal ablation product
Shape or particulate material and formed.These substances will be adhered in joint-cutting, and mainly be accumulated in joint-cutting exit site, serious shadow
The exclusion of galvanic corrosion product is rung, and it is very difficult that fresh working media is made to enter joint-cutting.Wire electrode provided by the invention is with electricity
The movement of polar filament electro-discharge machining, particularly screw type bulge-structure can be effectively injected more fresh working solutions, so as to
Workpiece and wire electrode surface is made to cool down in time, burned work-surface or lesion electrode silk is avoided, burning silk is caused when serious.Electric discharge
After, the screw type strip projected parts structure of wire electrode can store a large amount of ablation products, reduce processing bits and be attached to wire electrode
Fracture of wire probability so as to improve chip removal performance, is reduced in surface.Because sticking object and playing electric discharge is made to concentrate on the work on wire electrode
With, if it is poor to cool down radiating condition at this time, just it is likely to make the temperature at this to raise, it so may be after in continuous discharge
It is continuous to there are other processing bits to be attached near the point, a kind of vicious circle is so caused, finally results in burn or even fracture of wire at this.
In addition, zigzag shape strip projected parts around core surfaces spiral and under, to working solution from top to bottom have good water conservancy diversion make
With with from flushing effect because working solution falls along wire electrode superficial-helical so that form unobstructed liquid during wire
Scapus is improved from rinse capability, reduces wire electrode surface pressing, is enhanced cooling capacity, is prevented wire electrode since temperature is excessively high and make
Into blow, so as to improve cutting safety coefficient, reduce the broken string frequency.Meanwhile this zigzag shape strip projected parts cause work
Liquid tangentially flows into, and avoids and wire electrode surface collision, it is ensured that liquid in rotation shape falls, and forms more closely knit rotation water
Stream, generates substantial amounts of heat, prevents fracture of wire when greatly absorbing Wire EDM.Numerical control low-speed wire cutting Wire EDM
In the process, high-pressure flush is usually all used, because the speed ratio of current is very fast, without any alleviation, therefore in cutting process
Larger energy loss can be caused, is highly detrimental to promote cutting efficiency, this zigzag shape strip projected parts not only pass through
The high-pressure flush on wire electrode surface is less likely to occur to block, and bath speed can also be allowed more to stablize, discharge energy is avoided to scatter and disappear
Too early, be conducive to promote cutting efficiency.
