The wheeling portion U5 designates the power supply (the power supply of the memory unit 85) of the desired power supply (4) 2 electric machining. At this time, it is easy to select the desired reading and reading unit, and the first switching is performed in a state in which the user's capacity is turned on and off; = Γ: the first switching element portion; 5: = The data of the Ministry of Education; and the first release: Force: The data of the switching components are synchronized and opened and closed. Therefore, during the period of electrical discharge machining of the workpiece W, the high-frequency pulse voltage is applied to the line upper state in a predetermined shape, and the high frequency power is converted from the lower power supply key to the electric power state, and From the upper power supply unit and the lower side, the "frequency pulse voltage is applied to both sides of the line electrode 1 to supply power 318719 14 200819231. Fig. 2 shows the supply from the pulse oscillators 35a, 35b to the jth switching unit 25a or the 2 is a schematic diagram showing the relationship between the waveform of the pulse signal of the switching element unit and the power supply state for supplying power to the line electrode 1. As shown in Fig. 2, the first pulse oscillator 353 is supplied from the first pulse oscillator 353 to the second switching element portion 25a. The pulse signal is finely scheduled to repeat the pulse waveforms of the low level l and the high level H, and the pulse signal supplied from the second pulse oscillator 35b to the second switching element portion 25b is maintained at a low level, and the second switching element is maintained. When the 25b is opened, the result of the opening and closing of the i-th switching element unit is "the upper side power supply state". Conversely, the pulse signal supplied from the 帛2 pulse oscillating device 35a to the (!! switching element portion) is maintained at a low level. L, and from the second pulse The pulse signal supplied to the second switching element portion 25b of the undulator 35b is a pulse of a low level and a high level at a predetermined cycle, and the second switching element portion 25b is opened and closed while the second switching element portion 25a is open. Therefore, the lower side power supply state is obtained. Then, the pulse signal supplied from the first pulse oscillator 35a to the i-th switching element portion 25a and the pulse signal supplied from the second pulse oscillator 35b to the second switching element portion 25b are mutually In the case of the synchronized pulse waveform, the second switching element portion 25a and the second switching element portion are opened and closed in synchronization with each other, and thus the power supply state BF is obtained on both sides. The inventors of the present application learned from experiments that the line electrode It is difficult to generate a short circuit frequency or a wire electrode breakage of the workpiece W, depending on the material or wire diameter of the wire electrode 1, the liquid quality of the machining liquid used, or the supply of the machining liquid from each of the nozzles 65a and 65b. Quantity, material to be processed from the material boundary or 318719 15 200819231 The shape of the product to be processed w and the processing conditions vary, and the short circuit occurs when the power supply state is switched. Occurrence - the processing speed is not easy to increase. In addition, it can be known from experiments that the number of pulses in the state is too high, and the wire electrode is easily broken. X (4), for example, will be applied to the wire electrode in the upper power supply state! The sum of the number of pulses of the power-on voltage and the number of pulses applied to the line high-frequency pulse power in the lower power supply state is set to be the same as the number of pulses of the high-frequency pulse voltage applied to the line electrode 1 in the power supply state on both sides. When the number of pulses in the power supply state is set to less than 3, the wire electrode i fish is: The road often occurs and the machining speed is greatly reduced. In addition, when the number of pulses is set to 100,000 or more, the wire electrode The position of the discharge point between the two sides of the difference is not so dispersed toward the direction of the workpiece W, and the line electrode is liable to be broken. Further, the inventors of the present application have experimentally obtained /1: the frequency of occurrence of a short circuit with the workpiece is changed: when it is reached, the wire electrode is broken, for example, the above-mentioned proportional line. ★It is easy to cause short circuit' and more than 95% of them are easy to cause wire electrode breakage and =Γ brother, it can be seen that the wire electrode 1 and the added short circuit are under the condition that the upper side power supply state, ... shape and power supply on both sides are properly mixed. State to suppress. In the presence of 13G, the pulse-pulse m control unit 95 controls the first pulse 318719 16 200819231, the vibrator 35a and the second pulse, and the singer-- + 1U action' result, power supply control is performed in the way of the upper side power supply state and the lower side power supply state. Therefore, the sinister and the power supply control data on both sides are stored in advance in the sensation part 85^, and the short circuit of the electrode 1 and the workpiece W is appropriately determined. Short circuit and wire electrode disconnection. It is easy to increase production in the processing machine iso. In the wire electric discharge machine of the present invention, the source and the second main power source can be used to suppress overheating of the electrode of the π center line of the workpiece in the Λ and the thickness direction. f knives for the younger brother 1 main brother brother 3 map to show the main lightning power ridge W „ Wang Yuyuan has the brother 1 main power supply and the second main ^ original, the spring electric discharge processing device - the composition of the figure.

Further, the second φ-β is connected to the workpiece Wy, and the second main source 30b is connected to the second switching unit. 25b is connected to the lower side for the supply of Lei Qiu, and is connected to the bottom of the board of the workpiece. = The lower part of the first main power supply and the second main power supply 30b - Control unit 90a controls. On-line electric discharge machine; j 4 Π μ, +, ,, u # Other than the above, and the electric discharge machine of Fig. 1 is not 生, raw π w Μ The structure of 戍dU is the same, so the one shown in Fig. 3 is the same as the structural member shown in Fig. 1, and the symbol 1 of the same symbol used in the drawing of the 冓弟1 is marked. and In addition, 'the processing machine constituting the wire electric discharge machine 140 is given a new 318719 17 200819231 symbol 80A' and a new component symbol n〇A is given in the control skirt system. In the UQ towel of the processing machine, the second main power source 3〇a is connected to the upper portion in the thickness direction of the workpiece, and the second main power source is connected to the lower portion in the thickness direction of the workpiece W. From * 1 main power supply 30a to the discharge point impedance and from the 2nd main power supply _

The impedance to the discharge point is such that the position of each discharge point becomes closer to the center portion of the workpiece W in the thickness direction. As a result, the value of the discharge current between the wire electrode 丨 and the workpiece becomes smaller as the position of the discharge point becomes closer to the center portion of the workpiece w in the plate thickness direction. - Figure 4 is a schematic diagram showing the relationship between the discharge position (position of the discharge point) and the discharge current value when the wire electric discharge machine (10) is set to the side of the electric discharge machine (4). The solid line Li|| in Fig. 4 shows the above relationship. As a table test, the " ίίϋ system of the wire electric discharge machine (10) shown in Fig. i is shown by a broken line L2 in Fig. 4. The discharge current value indicated by the solid line 1 " and the discharge current value indicated by the broken line ^ are obtained under the same processing conditions. It can be clearly seen from Fig. 4 that the discharge current value between the wire electrode and the workpiece is either the position of the discharge point of the wire electric discharge machine i3〇 or i4〇, and the position of the discharge point is closer to the center of the thickness direction of the workpiece. The smaller the department becomes. The extent of the basin drop is greater at the time of the online electric discharge machine 140 than at the time of the online electric discharge machine. Further, in the case where the discharge current value in the center portion of the workpiece in the thickness direction of the workpiece is the same as the processing condition, the degree of downtime of the wire electric discharge machine 14 is smaller than that of the wire electric discharge machine 13 〇. : Generally speaking, the 'line electric discharge machine' supplies the machining fluid to the wire electrode between the workpieces' to thereby suppress the wire electrode during the electric discharge machining. 318719 18 200819231 heat, but in the plate of the workpiece The center portion in the thickness direction is less likely to be cooled by the machining liquid than the upper portion in the thickness direction of the workpiece or the lower portion in the thickness direction. Therefore, the wire electrode is overheated at the center in the thickness direction of the workpiece, and the wire electrode is broken. line.而 ' "In the wire electric discharge machine 14G shown in Fig. 3, the discharge current value at the time of power supply on both sides is closer to be added, so that it is in the direction of the plate thickness = valley easy suppression line electrode 1 After that. Therefore, it is easier to prevent the wire electrode from being broken than the line (4) described above with reference to the line placing machine described in the first embodiment. Therefore, according to the wire electric discharge machine 14G, in the same manner as the line discharge adding 130, the predetermined power can be opened, and the e-bend is opened, and the upper side power supply state and the lower side are combined.

With the power supply on both sides, you can prevent the wire electrode! It is easy to suppress the line power with the workpiece W, the ugly I, and the electric discharge machine (4). It is more productive than the line electric discharge machine. In the wire electric discharge machine, when z is produced by tr L / ^ or the knee (the relative height of the side power supply) is changed, the self-discharge is changed, and the P is... The distance will be changed to the power supply circuit of the upper power supply unit to the discharge point (the following: Emperor: poetry power supply circuit) and the electric power path to the discharge point through the lower power supply unit (hereinafter referred to as "the following example #雷帝,,' ' The difference between the impedances of the power supply circuits of the power supply circuits and the power supply circuit of the discharge currents of the power supply circuits is large. In the (small impedance supply), the valley is likely to cause the wire electrode to be broken. In the wire electric discharge machine of the present invention, the supply condition of the high-frequency pulse voltage for each of the upper-side power supply circuits is adjusted according to the deviation of the impedance between the upper power supply circuit and the side power supply circuit of 318719 19 200819231, The cause is that the wire electrode is broken due to the impedance deviation between the electric circuits. 5 to 7 are schematic diagrams showing the structure of the wire electric discharge machine which can prevent the wire electrode from being broken due to the impedance deviation of the power supply, and the structure shown in Fig. 1 : I/, and the same reference numerals are used for the component symbols used in the first drawing, and the description thereof is omitted. The wire electric discharge machine 150 shown in Fig. 5 is provided with a control device 110β having a pulse oscillation manufacturing system 95a. The pulse oscillation control unit reads data stored in the two-axis height of the memory unit 85 (the height of the upper power supply unit with respect to the lower power supply unit 2〇b) or stored therein. The z-axis height is obtained from the displacement control data of U-M5, and the z-axis height is compared with the reference value to determine the magnitude relationship between the impedances of the upper power supply circuit and the lower power supply circuit. Then, for example, the power supply control data read from the memory unit δ5 is changed by, for example, the discharge current value of the power supply circuit having a small impedance is close to the discharge current value of the power supply circuit having a large impedance. The unit 95a controls the operations of the first pulse oscillator 35a and the second pulse oscillator 35b based on the changed power supply control data. For example, adjust the supply to the line electrode by changing the pulse length or pulse interval at the high-frequency pulse voltage, or changing the number of pulses supplied! The high frequency pulse energy can adjust the discharge current value. When the first switching element unit 25a and the switching element unit 25b each have a plurality of switching elements, the number of switching elements that are open is changed, thereby adjusting the high-frequency pulse voltage of the supply 318719 20 200819231 to the line electrode 1. Energy. Further, in the above reference value, the two axes assumed when the power supply control data is created are used, and the reference value is stored in the memory unit 85, for example. This wire electric discharge machine is particularly suitable when a flat plate is used as the workpiece W. The wire electric discharge machine 160 shown in Fig. 6 is provided with a control device having a calculation-control unit 90b and a pulse ring control unit 95b. Calculus - Ministry of Engineering 90b and the first!
