Embodiment Construction

[0022] Describe the specific embodiment of the present invention according to above-mentioned accompanying drawing

[0023] figure 1 It is a block diagram of a two-stage structure current-type electric discharge machining power supply. Depend on figure 1 It can be seen that the output of the constant current output DC-DC converter is connected to the voltage-current composite pulse forming converter connected to the EDM machine tool, and the control and protection circuit connected to the EDM machine tool is connected to the voltage-current composite pulse forming converter. The characteristic of this kind of power supply is that the output voltage and current pulse of the converter is formed by the composite pulse of voltage and current, and the leading edge of the pulse is a peak higher than the pulse, followed by a low-voltage current constant current pulse.

Abstract

The invention refers to unresisted current type energy-saving electric spark processing pulse power, which is made up of filter circuit, DC-DC converter, PWM control circuit, constant current output DC-DC converter made up of current measuring circuit and voltage-current compound pulse converter. Compared with current traditional electric spark processing power, the invention has a higher efficiency, the energy-saving rate is high, the process precise is high.

Description

technical field [0001] The invention relates to a two-stage structure non-resistance current type energy-saving EDM pulse power supply Background technique [0002] Electric discharge machining (EDM) is a processing method that uses spark discharge to corrode metal to achieve metal cutting. It is an extremely important processing method in the world today and plays an irreplaceable role in the industry. [0003] As one of the important components in the EDM system, the EDM power supply has a great influence on the various indicators of EDM (such as processing efficiency, processing accuracy, electrode loss, power utilization rate, etc.). [0004] The EDM power supply has undergone many developments and innovations, and now there are many types of EDM power supplies, such as relaxation RC power supply, pulse generation EDM power supply, thyratron EDM power supply, Silicon-controlled EDM power supply, resistance current-limiting EDM power supply, etc. [0005] The above-ment...
