Description
Technical field
The present invention relates to an Albatra metal, more particularly to a kind of high zinc-aluminium ferromanganese for being used to manufacture unidirectional wire wire electrode
Copper alloy.
Background technology
Slow wire feeding spark discharge is processed, and China's metallurgy industry standard claims Digit Control Machine Tool to be added with unidirectional wire spark discharge
Work, professional domain also turn into 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 optical machinery processing method.From last century the eighties are incoming
State, have more than 30 years, China continent used unidirectional wire spark discharge electrode material on the market, 85%
The wire electrode that basis brass alloy used above is manufactured into, also there is least a portion of slow wire feeding user to use compound copper alloy electrode
Silk, but due to the backwardness of slow wire feeding electro-discharge machining popularization, composite electrode wire is also in the stage of the market expansion, most of users
Or from the wire electrode of the cheap basis brass material manufacture of cost.With the aggravation of market competition, cost of human resources
Improve, increasing user, which is intended to wire electrode manufacturing firm, can provide the electrode that cost is lower, more efficient, performance is more excellent
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, the wire electrode used in middle wire spark discharge processing method move back and forth, you can with by multiple discharge, and slow wire feeding electricity fire
Wire electrode one-way movement used in flower electro-discharge machining and only electro-discharge machining of progress are to be arranged by the chip removal system of cutting machine
Go out, the different differences for determining both machining accuracies of processing mode, therefore unidirectional wire (slow wire feeding machined electrode silk translational speed
It is slower than the wire electrode translational speed of middle wire, fast wire winding and be commonly called as processing for slow wire feeding) electro-discharge machining precision can reach micro-
Meter level, and middle wire, the machining accuracy of fast wire winding can only achieve silk level, this namely many precision optical machinery manufacture field selection is slow
The reason for travelling wire electrical discharge is processed.
During 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 adjusting means, to ensure that instrument and workpiece exist
The discharging gap (0.01~0.05mm) of a very little is maintained during normal process., just will at that time between pulse voltage is added to 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 of passage, discharge time pole
It is short, cause energy height to concentrate (10~107W/mm), TRANSIENT HIGH TEMPERATURE caused by region of discharge is enough to make melt material or even steamed
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 circulate down to high-frequency of so going round and beginning again, tool-electrode is continuous 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, forms required machining shape.At the same time,
The sub-fraction of gross energy is also delivered on tool-electrode, so as to cause tool loss.And the tool-electrode being lost constantly is arranged
Go out, the new tool-electrode (heretofore described high zinc-aluminium ferromanganese copper alloy electrode silk) without loss continuously supplies
Give, the shape of incisory tool-electrode a dynamic balance is all the time present, so as to ensure the dimensional accuracy of workpiece and table
Face finish.
The dual character of things determines that unidirectional wire spark discharge is machined with the advantages of notable, also determines its shortcoming
In the presence of because wire electrode used in unidirectional wire spark discharge processing only carries out an electro-discharge machining i.e. by cutting machine
Chip removal system is discharged, therefore the wire electrode material usage of slow wire feeding is very big, it is generally the case that one, a slow wire feeding lathe
The usage amount of the wire electrode of the moon is 150 kilograms, and the investigation that market department is taken charge of according to me counts, China's slow wire feeding electricity consumption of one month
Polar filament usage amount is 3000 tons, and slow wire feeding with wire electrode is formed with the copper and zinc metal compound of different proportion content, 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
Copper and Copper Ores, to meet the needs of China's industrial development, therefore how it is few with copper, economize on copper and turn into pendulum and add in each copper
Eternal problem in face of worker.
At present, for the preparation method of unidirectional wire spark eroding processing electrode wires, extrusion and water are typically taken
Horizontal continuous casting is realized：Above two method manufactures base bar, by intermediate annealing and pressure processing, core bar is made, then passes through again
The finished product processing and manufacturing in road is into the wire electrode of specification needed for client afterwards, but both approaches are present that preparation technology is complicated, process is numerous
The problems such as more, production equipment costliness (extruder wants 20,000,000 RMB), increase its production cost.If keeping integrating
On the premise of performance does not decline or even has lifting, 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 ablation process of discharging,
The V being adhered in cutting material on tool-electrode silk, Cr, Ni, Mo, Co, Ti, W, C, etc. element), while reduce wire electrode again
Copper content, increase its Zn content, the adverse effect brought is reduced to mitigate copper by alloyage process, improves its electrode material again
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, make it have the stronger market competitiveness.
