Description
Technical field
The present invention relates to the control system of AC welding set, specifically a kind of multi-head welder output control system and controlling party
Method.
Background technique
Multi-head welder is the welding equipment for multiple solder joints are synchronized with automatic welding.Realize Multipoint synchronous welding
Ideally one big transformer connects multi-group electrode, while pushing while welding.But transformer efficiency is too big, general work
Factory's power grid is difficult to bear, and in addition allows the electric current of each solder joint unanimously also relatively difficult.There are two types of conventional solutions: 1, only with one
A transformer, each point weld in turn, and every group welding electrode controls its movement by a cylinder, and control system controls welding movement
Mechanism once only pushes a cylinder, and each cylinder, which successively acts, completes multi-point welding；2, it is respectively corresponded using multiple small transformers
Multi-group electrode controls each transformer using multiple controllers respectively, and when welding, electrode pushes simultaneously, is powered simultaneously.Above-mentioned
Cost is relatively low for a kind of scheme, but every group of electrode is successively acted by respective lower air cylinder, and consuming time is long, and welding efficiency is low；
Second scheme speed of welding is fast, but multiple controllers need to be arranged, and circuit cost is higher.
Summary of the invention
That the technical problem to be solved by the invention is to provide a kind of circuit structures is simple, at low cost, speed of welding is much faster
Head welding machine output control system and control method.
Multi-head welder output control system of the invention includes a medium frequency inverter alternating-current controller, input terminal connection three
Phase AC power source, output end are parallel with multiple groups transformer circuit, and the output end of every group of transformer circuit connects group welding electricity
Pole, is provided with the switching device for capableing of on or off transformer circuit in every group of transformer circuit, in each transformer circuit
Switching device can be triggered in turn by a control module.
Further, the switching device is silicon controlled module；Each controllable silicon module includes two and in parallel connects
To opposite silicon-controlled.
Multi-head welder output control method of the invention is based on above-mentioned control system, and welding process is: starting intermediate frequency is inverse
Become alternating-current controller, to each transformer circuit out-put supply；Each switching device is turned off before welding, each transformer circuit not work
Make, each group welding electrode presses against on solder joint；After starting welding, is successively triggered and ended according to the step sequence of setting by control module
Each switching device puts into each transformer circuit successively, and each group electrode is made to be sequentially output welding current, completes multi-point welding.
The invention has the advantages that 1, welding process each group electrode is pushed simultaneously in place, without the multiple of multiple groups welding electrode
Mechanical action, and successively start each welding circuit by control module, substantially increase speed of welding；2, it is handed over by a medium frequency inverter
Each transformer circuit of stream controller wheel flow control, circuit structure is simple, and equipment investment is few, reduces costs.
Detailed description of the invention
Fig. 1 is the circuit diagram of multi-head welder output control system embodiment of the present invention.
Specific embodiment
As shown, the multi-head welder output control system includes a medium frequency inverter alternating-current controller, input terminal connects
Three-phase alternating-current supply is connect, output end is parallel with multiple groups transformer circuit 1, and the output end of every group of transformer circuit connects one group of weldering
Receiving electrode 2, is provided with that be capable of the switching device 3 of on or off transformer circuit be silicon-controlled mould in every group of transformer circuit
Block；Each controllable silicon module includes two and in parallel connects to opposite silicon-controlled.
The control method of above-mentioned control system is: when welding, starting medium frequency inverter alternating-current controller, to each transformer circuit
Out-put supply；Each silicon controlled module is turned off before welding, and each transformer circuit does not work, and each group welding electrode presses against solder joint
On；After starting welding, each silicon controlled module is successively triggered by control module and ended according to the step sequence of setting, returns each transformer
Road is successively put into, and each group electrode is made to be sequentially output welding current, completes multi-point welding.
