Description
Technical field
The present invention relates to an Albatra metals more particularly to a kind of for manufacturing the high zinc-aluminium manganese iron of unidirectional wire wire electrode
Copper alloy.
Background technique
The processing of slow wire feeding spark discharge, China's metallurgy industry standard claim numerically-controlled machine tool to be added with unidirectional wire spark discharge
Work, professional domain also become galvano-cautery processing (English abbreviation EDM:Electrical Discharge Machining), electrode
Silk is a kind of slow wire feeding spark discharge processing Tool-electrode material used.
Unidirectional wire spark discharge processing method is a kind of precision machinery processing method.From last century the eighties it is incoming in
State has had more than 30 years, China continent on the market used in unidirectional wire spark discharge electrode material, 85%
Wire electrode caused by basis brass alloy system used above also has least a portion of slow wire feeding user to use compound copper alloy electrode
Silk, but due to the backwardness that slow wire feeding electro-discharge machining is popularized, stage of the composite electrode wire also in the market expansion, most users
Still the wire electrode of low-cost basis brass material manufacture is selected.With the aggravation of market competition, cost of human resources
It improves, more and more users, which are intended to wire electrode manufacturing firm, can provide that cost is lower, more efficient, performance more preferably electrode
Silk.
Slow wire feeding spark discharge processing method is a kind of different from fast wire winding, the electric discharge machining method of middle wire, is hurried up
Silk, wire electrode used in middle wire spark discharge processing method move back and forth, it can pass through multiple discharge, and slow wire feeding electrical fire
Wire electrode one-way movement used in flower electro-discharge machining and only electro-discharge machining of progress are to pass through the chip removal system row of cutting machine
Out, the different differences for determining the two machining accuracy of processing method, therefore unidirectional wire (slow wire feeding machined electrode silk movement speed
It is slower than the wire electrode movement speed of middle wire, fast wire winding and be commonly called as slow wire feeding processing) electro-discharge machining precision can achieve it is micro-
Meter level, and the machining accuracy of middle wire, fast wire winding can only achieve silk grade, this namely many precision machinery manufacture field selection is slow
The reason of travelling wire electrical discharge is processed.
When unidirectional wire spark discharge processing, a pole bonding tool electrode of the pulse power, another pole connects piece pole (such as
Shown in Fig. 1), the two poles of the earth, which are immersed in the liquid medium with certain insulativity, (commonly uses kerosene or mineral oil or deionized water, unidirectionally
Wire linear cutter often uses deionized water).Tool-electrode is controlled by auto-feed regulating device, to guarantee that tool and workpiece exist
The discharging gap (0.01~0.05mm) of a very little is maintained when normal process.It, just will at that time when pulse voltage is added between the two poles of the earth
Under the conditions of interpolar closest approach liquid medium breakdown, formed discharge channel.Due to the sectional area very little in channel, discharge time pole
It is short, cause energy height to concentrate (10~107W/mm), the TRANSIENT HIGH TEMPERATURE that region of discharge generates is enough to steam material fusing even
Hair, so that forming galvano-cautery small rut one by one.After in first time, pulsed discharge terminates, process very short interval time, the
Two pulses so recycle down to high-frequency, tool-electrode is continuous in cycles again in another interpolar closest approach disruptive discharge
Ground is fed to workpiece, and the shape of its walking is finally just replicated on workpiece, machining shape required for being formed.At the same time,
The sub-fraction of gross energy is also delivered on tool-electrode, to cause tool loss.And the tool-electrode being lost constantly is arranged
Out, the new tool-electrode (heretofore described high zinc-aluminium manganese iron-copper wire electrode) not being lost continuously supplies
It gives, so that the shape of incisory tool-electrode is there is a dynamic balance always, to guarantee the dimensional accuracy and table of workpiece
Face finish.
The dual character of things determines that unidirectional wire spark discharge is machined with significant advantage, also determines its disadvantage
In the presence of because wire electrode used in unidirectional wire spark discharge processing only carries out an electro-discharge machining and passes through cutting machine
Chip removal system discharge, therefore the wire electrode material utilization amount of slow wire feeding is very big, it is generally the case that one one, slow wire feeding lathe
The usage amount of the wire electrode of the moon is 150 kilograms, is counted according to the investigation of our company market department, China's slow wire feeding electricity consumption in one month
Polar filament usage amount is 3000 tons, made of slow wire feeding is copper and zinc metal compound with different proportion content with wire electrode, therefore
Consumption to copper and zinc is huge.
It is well known that China is the barren country of a copper reserves, to be largely electrolysed from Africa, South America import every year
How copper and Copper Ores to meet the needs of China's industrial development, therefore become pendulum with copper, saving copper less and add in each copper
Eternal project in face of worker.
Currently, generally taking extrusion and water for the preparation method of unidirectional wire spark eroding processing electrode wires
Horizontal continuous casting is realized: core bar is made by intermediate annealing and pressure processing in above two method manufacture base bar, then using
The finished product in road fabricates the wire electrode at specification needed for client afterwards, but there are preparation process complexity, process are numerous for both methods
More, the problems such as production equipment is expensive (extruder wants 20,000,000 RMB), increase its production cost.As can keeping integrating
Under the premise of performance does not decline or even has promotion, made using the Tool-electrode material (present invention is also electric discharge waste silk) after overdischarged
For raw material, by the purifying method of metal remove the impurity component in electric discharge waste silk content (in electric discharge ablation process,
The V being adhered in cutting material on tool-electrode silk, Cr, Ni, Mo, Co, Ti, W, C, etc. elements), while reducing wire electrode again
Copper content increases its Zn content, and mitigating copper by alloyage process reduces bring adverse effect, and improves its electrode material
Discharge performance, and simplify its production technology (present invention is using Continuous Up casting technique), then can reduce former material
Expect to improve spark eroding processing efficiency again while cost, makes it have the stronger market competitiveness.
