The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
A kind of electric welding machine auto-power-cutting battery saving arrangement, as shown in Figure 3, comprising insulation fixed head 3, be installed with A.C. contactor 4 and plastic casing 7 respectively on the insulation fixed head 3, A.C. contactor 4 upper ends are equipped with power access end 1 and power access end 22 respectively, and A.C. contactor 4 lower ends are equipped with elementary winding incoming end 1 and elementary winding incoming end 25 respectively; Adjustable resistance 8 is installed on the plastic casing 7; Insulation fixed head 3 trailing flanks are equipped with printed circuit board (PCB); as shown in Figure 2; comprise on the printed circuit board (PCB): dc working power circuit; multivibrator circuit; zero load or operation test circuit; idle time, circuit was adjusted in control; the control circuit holding circuit; carry out signal circuit; the operation holding circuit; dc working power circuit links to each other with multivibrator circuit; multivibrator circuit divides two-way; one the tunnel links to each other with electric welding machine T1; another road links to each other with zero load or operation test circuit; zero load or operation test circuit divide two-way; one the tunnel links to each other with electric welder transformer T1; another road is adjusted circuit with control idle time and is linked to each other; control idle time is adjusted circuit and is divided two-way; one the tunnel with the operation holding circuit link to each other; another road links to each other with the control circuit holding circuit; electric welder transformer T1 links to each other with the operation holding circuit; the operation holding circuit links to each other with the execution signal circuit; carry out signal circuit and divide two-way; one the tunnel links to each other with A.C. contactor KM; another road links to each other with the control circuit holding circuit, and A.C. contactor KM links to each other with electric welder transformer T1.
In the present embodiment, as shown in Figure 1, T1 is the A.C. welder transformer, and power switch HK connects back power transformer T2 at first, obtain the DC voltage about 12V on the filter capacitor C1, IC1, IC2 are two time-base integrated circuits, because voltage is 0 on the original state capacitor C 2, time-base integrated circuit IC1 2., 6. pin is a low level, so time-base integrated circuit IC1 3. pin is a high level, not adhesive of relay K, A.C. contactor KM does not work, and electric welding machine is not switched on; Meanwhile, start working by the multivibrator that time-base integrated circuit IC2 etc. forms, time-base integrated circuit IC2 3. pin output frequency is a pulse signal about 10KHZ, this signal divides two-way after resistance R 5, one the tunnel is added to an end of T1 level of electric welder transformer, the electric welder transformer T1 time level other end and control circuit " " link to each other, because electric welder transformer T1 secondary windings is very big to the induction reactance that the 10KHZ signal presents, so this loop current is very little, the output voltage of transformer L is also minimum, another routing capacitance C4 coupling, diode VD8, the VD9 rectification, obtain DC voltage after capacitor C 5 filtering and make triode VT1 conducting, triode VT2 ends, so capacitor C 2 no charging currents, and time-base integrated circuit IC1 3. pin keeps high level, light emitting diode VD10 lights, and circuit is in unloaded electricity-saving state.
During welding, welding rod touches mutually with workpiece, the pulse signal of time-base integrated circuit IC2 output is by short circuit, and triode VT1 loses bias current to be ended, triode VT2 conducting, 12V voltage charges to capacitor C 2 by triode VT2, time-base integrated circuit IC1 2., 6. the pin current potential is raised to rapidly more than the 2/3VCC, and time-base integrated circuit IC1 3. pin upset is low level, relay K adhesive, make A.C. contactor KM adhesive, electric welder transformer T1 gets electric work.Because the normally-closed contact K-2 of relay K disconnects before prior to normally opened contact K-1 closure, so secondary 30-35V alternating voltage can not scurried into control circuit during electric welder transformer T1 work.After the normally-closed contact K-2 of relay K disconnected, the time-base integrated circuit IC2 3. pulse of pin output made triode VT1 conducting again, and triode VT2 ends, and 12V voltage stops the charging of capacitor C 2 by triode VT2.But the very big operating current of electric welding machine this moment makes among the current transformer L and induces voltage, this voltage by diode VD5 rectification after to capacitor C 2 charging, make time-base integrated circuit IC1 2., 6. the pin current potential remains on more than the 1/3VCC, time-base integrated circuit IC1 3. pin keeps low-voltage, relay K, A.C. contactor KM keep adhesive, Light-Emitting Diode VD11 lights, electric welder transformer T1 operate as normal.The effect of DW is to make time-base integrated circuit IC1 2., 6. pin voltage maximum is no more than VCC (12V) in the circuit, and Light-Emitting Diode VD10 is the standby indication, and Light-Emitting Diode VD11 is the work indication.
When stopping to weld, electric welder transformer T1 secondary current disappears, and induced voltage also disappears among the transformer L.Capacitor C 2 is through resistance R 2 discharges, after arriving setting-up time, time-base integrated circuit IC1 2., 6. the pin current potential is low to moderate 1/3VCC, and time-base integrated circuit IC1 3. pin turns over and is high level, relay K, A.C. contactor KM discharge in succession, and electric welding machine is got back to the power save mode of idle power-off.R2 is an adjustable resistance, can adjust electric welding machine from stopping to be welded to the time of automatic outage by regulating adjustable resistance R2.
In the present embodiment, be welded on electronic devices and components of the present utility model on the one bar printing wiring board and in the plastic casing of packing into, be fixed on the insulation fixed head with A.C. contactor, light emitting diode VD10, light emitting diode VD11 and adjustable resistance R2 are fixed on the front of plastic casing, the utility model is fixedly mounted on the electric welding machine shell, as shown in Figure 1 transformer L is positioned on secondary output end of electric welder transformer T1, carefully connect the wire then, again with the power access end one and the power access end two of AC power incoming transport contactor, the elementary winding incoming end one and the elementary winding incoming end two of the elementary winding of electric welder transformer T1 two ends incoming transport contactor, connect AC power, electric welding machine can be realized unloaded power-saving running.
The utility model has adopted the integrated control circuit of all-electronin, and installation easy-to-connect, need not change electric welding machine, do not influence the original performance of electric welding machine, automatically the time user who has a power failure when unloaded can regulate as required voluntarily, can rationally control the power off time after the zero load like this, accomplish to economize on electricity and can reduce the number of times of A.C. contactor action, can prolong the service life of electric welding machine.Control circuit protection that the utility model is also ad hoc, when electric welding machine was worked, secondary alternating current just can not scurried into control circuit, thereby has guaranteed the reliability of control circuit like this.Power savings of the present utility model is remarkable, and the electric currents of several peaces in the time of can be zero load even tens peaces drop to tens milliamperes.Therefore, the utility model working stability is reliable, and is highly sensitive, and the electric welding machine starting the arc is easy, and fault rate is low, power savings is remarkable.
