Abstract
The utility model relates to a non industrial frequency transformer spark processing machine tool kickback type of power supply, composed of a circuit part, a casing, a starting switch, a regulating turn knob and a current meter. Main power outputs voltage with high voltage direct current to the convertor by the full-wave bridge rectification of a high-voltage rectifier; the convertor outputs high frequency pulse with low voltage and alternating current to a high-frequency rectifier by inverse transformation according to the pulse frequency and the duty ratio given by a waveform generator; the high-frequency rectifier outputs the voltage with high frequency and direct current for the use of spark processing machine tools.
Description
The utility model relates to a kind of power supply, and specifically describing is a kind of idle frequency power transformer electric spark machine tool pulse power.
At present the electric spark machine tool pulse power power consumption of usefulness is bigger, and is little hundreds of watts, bigger thousands of watts so that bigger, so 50H
zIndustrial Frequency Transformer its weight, volume and cost in the electric machining pulse power all hold pride of place, although converter upgrades along with the development of electronics science, experience electron tube, controllable silicon, double pole triode are to V
MosTriode.Its basic structure does not have big variation, so weight, volume and cost decline are also little.
The purpose of this utility model is to cancel 50H
zIndustrial Frequency Transformer significantly descends power supply and weight, volume and cost.
To achieve these goals, the utility model adopts following technical scheme:
A kind of no industrial frequency transformer electric spark machine tool pulse power, comprise circuit and shell, on shell (7) panel power regulating switch (8) is housed, starting switch (9), duty cycle adjustment knob (10), power adjusting knob (11), ammeter (12), shell one side is equipped with to exchange and is introduced socket (13), it is characterized in that circuit is by high pressure bridge rectifier (1), contravariant transformer (5), large power triode (6), waveform generator (4) and hf rectifier (3) are formed, contravariant transformer primary coil one termination high-voltage rectifier positive output end, another termination large power triode colelctor electrode, contravariant transformer secondary coil two termination hf rectifiers, large power triode base stage welding wave generator, emitter stage is welding wave generator and high pressure bridge rectifier negative output terminal respectively.
The circuit of converter can adopt single-ended, multiterminal form according to the power output size.
Good effect of the present utility model is to cancel Industrial Frequency Transformer, and weight, volume and the cost of power supply are significantly descended.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a schematic appearance of the present utility model;
Fig. 2 is the utility model circuit theory diagrams.
Among Fig. 1, the 7-shell, the 8-power regulating switch, the 9-starting switch, 10-duty cycle adjustment knob, 11-power adjusting knob, 12-ammeter, 13-exchange introduces socket.
Shown in Fig. 1-2, civil power exchanges after high-voltage rectifier 1 full-wave rectification for 220 volts, export nearly 300 volts of direct currents and give converter 2, contravariant transformer 5 transformation ratios are set as required, if transformation ratio is set 3:1, then converter 2 outputs exchange high-frequency impulse for 100 volts and give hf rectifier 3, and 100 volts of high frequency DC pulses of hf rectifier 3 outputs use to electric spark machine tool.Pulse frequency is given by waveform generator 4, and the frequency height can be regulated by frequency adjustment knob 11, and dutycycle is regulated by duty cycle adjustment knob 10, and the power output size is regulated current-limiting resistance R by power regulating switch 8 and realized.
The utility model is suitable for the input AC civil power, the output DC pulse.The circuit of converter 2 can adopt single-ended, multiterminal form according to the power output size, and shown in Fig. 2 is single-ended scheme circuit.
