Cutting mill bed) it is gradually popularized in electric machining industry, the technologies such as mechanical precision, position-force control, high frequency electric source all reach
Higher level, such as: constant tension device is installed and used, and used tracking process control technology etc., so that because of wire machine
Molybdenum filament radial vibration amplitude caused by structure constantly reduces, and it is relatively stagnant to implement active technology to space form and position
Afterwards, space form and position caused by molybdenum filament Discharge Force is increasingly becoming the main reason for influencing precision, is always to hinder processing matter
The technical problem that amount and efficiency improve.Existing wire cutting machine tool, molybdenum filament stress are mainly the active force (Discharge Force) of discharge channel
With axial tensile force etc., (such as Fig. 1, below letter when molybdenum filament is generated space form and position by laterally (radial direction) Discharge Force effect
Claim form and position), it is necessary to molybdenum filament deviation guide wheel outer fulcrum is limited by two guide holes above and below processing sections molybdenum filament (to be cut

When left coil 1 and right coil 2, preceding coil 3 and after 4 two pairs of coils of coil pass to same direction current (each pair of coil respectively
Series connection), magnetic field superposition enhancing simultaneously forms approaches uniformity magnetic field in each pair of magnetic pole end intermediate region (i.e. molybdenum filament channel 5), and two pairs
Magnetic pole end in coil is mutually perpendicular to make intermediate region that a Vector Magnetic Field can be obtained that (straight wire (molybdenum filament) current direction is constant, magnetic
Field direction and ampere force direction have corresponding relationship, due to force resolution and synthesis describe in this application it is more intuitive, below it is equal
It is described with vectorial force).
Description and understanding to technical scheme for convenience, left coil 1 and right coil 2 are known as X to line by us
Circle, the axis of the two are X-axis.Preceding coil 3 and rear coil 4 are known as Y-direction coil, the axis of the two is Y-axis.
The basic principle of above-mentioned design is as follows: when passing to same direction current respectively in two pairs of coils, in two pairs of magnetic pole ends
Between have orthogonal two magnetic field, molybdenum filament sheet is placed in magnetic field intermediate region (i.e. molybdenum filament channel 5) as conducting wire always, when it
No current in molybdenum filament when being not in discharge condition, also just not by the effect of Ampere force；Height is wherein flowed through when processing electric discharge
Frequency Rectified alternating current, at this moment molybdenum filament Ampere force by two mutually perpendicular directions respectively in orthogonal two magnetic field
(X' and Y'), the factors such as the size and Orientation and coil current, molybdenum filament electric current of each power related (1, other factors such as coil turn
Etc. parameters be considered constant for the time being；2, molybdenum filament average operating current can be set by high frequency electric source parameter, i.e. molybdenum filament is averaged work
Make known to electric current), and molybdenum filament is depended on X', Y' both direction Ampere force size and direction by resultant force size and Orientation.It is logical in this way
Size of current and direction (molybdenum filament electric current is identical) in two coils of control are crossed, the power of any direction in available plane.Due to putting
Power direction and direction of feed according to digital control system machining locus on the contrary, can obtain current kinetic direction, as long as then two magnetic
The direction that field generates practical resultant force to molybdenum filament is identical as the direction of motion, so that it may offset the influence of Discharge Force.
When a pair of of coil passes to same direction current, approaches uniformity magnetic field is generated in region therebetween.If with above-mentioned line
A pair of of coil is placed in coil axis vertical direction again, and passes to same direction current, then there are two orthogonal in intermediate region
Magnetic field.If changing current direction, magnetic direction also changes, and coil current, magnetic field and ampere force direction relationship are shown in Table 1.It is logical
Electric straight wire (molybdenum filament) is centainly acted on by Ampere force in above-mentioned two magnetic field, and electromotion straight wire (molybdenum filament) stress is two
The resultant force of direction Ampere force.
Table 1: coil current, magnetic field and ampere force direction
Note: molybdenum filament current direction is constant
Ampere force size is directly proportional to electric current, coil magnetic field intensity and magnetic fields length, according to Discharge Force model in design
Enclose the parameters such as determining magnetic permeability μ, the number of turns, coil radius.It offsets resultant direction to obtain from current working motion course bearing, offset
Resultant force size is determined by high frequency machined parameters, will be decomposed into two mutually perpendicular Ampere forces of X', Y' with joint efforts.It is big by X' Ampere force
It is small to be calculated with direction, control x-ray loop current size and Orientation (molybdenum filament electric current is identical), to obtain X' Ampere force size and side
To；It can be calculated by Y' Ampere force size with direction, control Y coil current size and Orientation (molybdenum filament electric current is identical), to obtain
Y' Ampere force size and Orientation.
Because wire cutting discharge process is extremely complex, when discharge, the factors such as immediate current size it is unpredictable, this dress
Set dexterously with Discharge Force there is synchronous, direct ratio to apply characteristic using Ampere force, i.e. electric discharge causes Discharge Force and generates electric discharge electricity
Stream, discharge current generates Ampere force in magnetic field simultaneously, and two power sizes are also directly proportional to discharge current.Discharge Force and Ampere force
Simultaneously occur it is contrary cancel out each other, thus dexterously reduce molybdenum filament form and position.Due in process, molybdenum filament short circuit shape
State odds very little, but electric current generation is also had at this time, in order to avoid the Ampere force as caused by short circuit current, between
Gap voltage collection circuit existing short-circuit signal enables coil current, once that is, short-circuit signal effectively closes coil electricity immediately
Stream-is without magnetic field.
Discharge current is to provide (upper and lower two conducting blocks realization by the way that both sides molybdenum filament above and below workpiece (two branches) is in parallel
The confession of the upper and lower mobile molybdenum filament in both sides is electrically accessed and (needs both ends to exert a force just), as shown in Figure 2), i.e., molybdenum filament electric current in down devices
Size is identical, but contrary, and in order to allow, Ampere force size is identical in two devices, direction is consistent up and down, then needs
Lower two devices coil size of current is identical, but opposite (the two coil first and ends access phase of the current direction of corresponding upper lower coil
Instead).
It refers again to shown in Fig. 3, above-mentioned magnet ring 6 includes: coaxially arranged upper ring body 601 and lower ring body 602, described in connection
