Description

Multiple resistance capacitor discharge machining system

The present invention relates to a micro-discharge machining system, and more particularly to an electric discharge machining system having a plurality of transistors for controlling a plurality of capacitors for charging and discharging.

In recent years, with the advancement of related technologies such as semiconductors, electronics and machinery, the products have been developed in the direction of micro and refinement. EDM is one of the main processing methods, and the improvement of the discharge power supply is for each manufacturer. The direction of technological development.

Therefore, many manufacturers apply for many patents for self-developed power supplies, such as the patent proposed by Charmilles Co. Ltd in the United States (US 6727455B1), the circuit uses 0.1~10MHz ultra-high frequency AC voltage to make the anions and cations oscillate in the discharge gap. The impact produces an arc-inducing effect but does not touch the workpiece, so there is no electrolytic effect, and immediately after the arc-triggering, it switches to a negative discharge, increasing the metal cutting rate. Mitsubishi Co. Ltd. also published a patent (US 6727455B1), in which it is proposed that the residual energy existing in the discharge gap after the discharge affects the gap condition at the next discharge, and also directly affects the surface precision after the workpiece is processed. Therefore, when the company uses AC discharge, the discharge circuit of opposite polarity is used as the residual energy of the excess discharge gap, thereby increasing the discharge frequency to increase the discharge efficiency. Another company, Sodick Co. Ltd, published a patent in the United States (US 6130395A), which uses two sets of DC voltages to match two sets of transistors, which are first roughed and then refined to produce a surface roughness Rmax. Less than 1 μm. Consortium The Institute of Industrial Technology also proposed a patent (I 413559), which uses two sets of power sources for discharge. The high-voltage arc-igniting power supply is mainly for induced discharge. The low-voltage discharge power module is mainly used for processing. Voltage detection will be performed, and the low-voltage power supply will be adjusted to accurately control the single-shot EDM energy to achieve high efficiency and energy saving. Yan Mutian and other scholars also proposed a patent on the electric discharge machining power supply (I 357840). This circuit uses a bridge converter to convert the positive and negative poles of the DC power supply. This method can provide a stable power supply during EDM and can also avoid The electrolysis phenomenon generated when the DC power source is discharged reduces the deterioration layer of the workpiece. At the same time, a set of mechanism circuit for removing excess voltage is added to avoid the interference of the negative power supply of the previous one when discharging the positive electrode, and to avoid the interference of the positive and negative power sources of the previous one when the negative positive discharge is avoided, so as to reduce the discharge during rapid discharge. Loss to improve efficiency.

In the prior art, electrical discharge machining (EDM) is divided into transistor discharge and single electricity. The two circuits of the resistance capacitor discharge, the transistor discharge circuit, it releases too much energy at one time, and the material is relatively removed, so that the processing speed is fast, but the processing precision is not high, and does not meet the requirements of micro-machining. In view of this, in the development of microfabrication, resistor-capacitor discharge loops are often used. This method mainly uses the charge and discharge principle of capacitors to generate high currents instantaneously, causing electrons to jump between the tool and the tool, generating nearly 10,000 degrees of high temperature, and then shifting. In addition to materials. Although the temperature generated is high, the time is short, the single-energy energy is not high, and the range of material removal is small, so that good surface roughness can be maintained. However, because the resistor-capacitor discharge circuit needs to satisfy the condition that the two electrodes are at a certain small distance and the capacitor is full of charge, the discharge can be discharged. The conventional resistor-capacitor discharge circuit discharges with a single capacitor, so that the number of discharges is small at a fixed time, and the processing efficiency cannot be improved.

In response to the above problems, the present invention provides a multiple resistor-capacitor electrical discharge machining system. The charging and discharging unit is composed of a plurality of transistors and a plurality of capacitors, and the charging and discharging units are respectively discharged according to a timing to increase the number of discharges in a fixed time and improve the electrical discharge machining process. The multiple resistance capacitor electrical discharge machining system comprises: a control module, a digital circuit module, a driving circuit module and a discharging circuit module.

The control module is a computer, and the control module provides a user input finger The method is suitable for controlling an electrical discharge machining system; the digital circuit module is a programmable logic device adapted to process the control program and output a timing signal; the driving circuit module is adapted to amplify the timing signal and output a driving signal to the discharging circuit module The discharge circuit module includes a plurality of transistors and a plurality of capacitors, and the discharge circuit module controls and drives a plurality of transistors according to the driving signals to perform high frequency open (open) and closed (channel) operations, thereby controlling a plurality of The capacitor is charged and discharged multiple times to perform an electrical discharge machining process, and the aforementioned high frequency range is between 0.1 and 10 MHz.

Firstly, the charging time required for each capacitor can be obtained by using Equation 1, and other capacitors are added in the charging time of each capacitor to discharge the capacitors to increase the processing efficiency of the discharge circuit. The method adopted by the invention is that all capacitors are filled with electric charge to reach a saturated state, and discharge is started from the capacitor C1. When the capacitor C1 is discharged, the capacitor C2 is continuously discharged. At this time, the capacitor C1 enters a charging state, and after the capacitor C2 is discharged, the capacitor C2 is discharged. , in order.

Compared with the prior art, the multiple resistance capacitor electric discharge machining system provided by the invention can improve the number of discharges of the electric discharge machining process in a fixed time and improve the processing efficiency of the single resistance capacitor discharge circuit. Moreover, since the single discharge time is shorter than the conventional technique, the discharge energy is lower than that of the prior art, so that the workpiece after processing has a good surface roughness. It has been experimentally confirmed that the multiple resistance-capacitor electrical discharge machining system provided by the present invention is placed in a single-resistance capacitor discharge circuit of the prior art. The electric feed rate can be increased by more than 60%.
