Description
The utility model relates to a kind of electric welding machine.
What existing alcohol-free spot welding method special-purpose in the electric light source industry adopted is that individual pulse combines with the pulse width compensation, make and realize by the constant mode of the pulse area of each pulse of silicon controlled, adopt this kind method, though guarantee each pulse of controllable silicon conducting and output enough energy are arranged all, but because the width of pulse has broadened, the voltage transient value is diminished, like this, also diminish immediately by the voltage that transformer produced, the instantaneous energy shortage that produces is so that workpiece local solder joint fusing, particularly those bigger or thick workpiece.Adopt said method, will use the low but expensive welding material of a kind of like this fusing point of tantalum piece inevitably.
Goal of the invention of the present utility model is to provide a kind of need not just can make the local solder joint fusing of workpiece, the alcohol-free mash welder that workpiece is welded together moment by tantalum piece.
The utility model is to realize like this, comprise welding mechanism, transformer, the voltage output-controlling device, wherein welding mechanism is mainly by movable solder joint, fixing solder joint compression spring, pedal constitutes, compression spring links to each other with movable solder joint, pedal links to each other with compression spring, movable solder joint, fixedly solder joint links to each other with two outputs of transformer respectively, its special feature is that the voltage output-controlling device is mainly by two controllable silicons, time control circuit, sawtooth wave oscillation circuit, oscillation frequency control circuit, squaring circuit, the whole wave rectification circuit constitutes, two silicon controlled anodes, negative electrode links to each other with two inputs of extraneous AC power respectively, two silicon controlled negative electrodes, anode links to each other with two inputs of transformer respectively, time control circuit links to each other with two silicon controlled trigger electrodes, sawtooth wave oscillation circuit links to each other with time control circuit, oscillation frequency control circuit links to each other with sawtooth wave oscillation circuit, squaring circuit links to each other with sawtooth wave oscillation circuit, the whole wave rectification circuit links to each other with squaring circuit, and the whole wave rectification circuit links to each other with two inputs of extraneous AC power.
During work, the whole wave rectification circuit becomes direct current with AC rectification, squaring circuit is shaped to square wave with direct current, by sawtooth wave oscillation circuit square wave is shaped to sawtooth waveforms then, the effect of oscillation frequency control circuit is the sawtooth wave frequency that the shaping of control institute is come out, the effect of time controller is the quantity that control outputs to the silicon controlled sawtooth waveforms, and the effect of switch and rectification is played in the silicon controlled effect.Owing to adopted sawtooth waveforms to control the silicon controlled conducting, make also indentation of the voltage waveform that is input on the transformer, increased the transient of voltage, the voltage of transformer moment output is increased, the energy of moment output also strengthens immediately, the local solder joint of workpiece is melted workpiece is welded together.
Compared with the prior art the utility model has and need not just can make the local solder joint fusing of workpiece, the advantage that workpiece is welded together moment by tantalum piece.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the circuit diagram of the utility model voltage output-controlling device.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
