Abstract
The utility model relates to a multifunctional DC arc welder. The multifunctional DC arc welder can output heavy current for common welding, and output low current for welding thin plates, or the low current can serve as a power supply for argon arc. An iron core of a transformer of the welder is in a shape like the Chinese character 'tian'. Each phase is composed of two secondary windings. The two secondary windings are respectively arranged on the upper and the lower sides of the iron core to be serially connected. The coarse adjustment of changing the size of output current is carried out by adjusting a connecting sheet to seal and connect the tail end of a three-phase secondary loose coupling winding or the tail end of a three-phase secondary tight coupling winding. The utility model has the advantages of a good dynamic characteristic and a big use surface.
Description
A kind of direct current that the utility model belongs in the electric welding machine is used welding machine more.
The ZXG of existing manufacturer production and market sale
5Series tap flow-regulating type arc welder, shortcoming of ubiquity.The Current Regulation narrow limits does not reach the requirement of Ihmin/Ie≤0.25 of standard laid down by the ministries or commissions of the Central Government JB1372-74 regulation.Do not have little electric current output, can not weld thin plate, more can not make argon arc welding power source.Thereby the range of application and the market sales volume have been influenced.For example: the ZXG that electric welder factory, the west of a city, Huadian City produces
5-200 type silicon rectifying arc welders, minimum output current are also greater than 85 peaces.
The purpose of this utility model is: avoid the deficiency in the above-mentioned technology, provide a kind of dynamic characteristic good, can satisfy general DC welder requirement of welding, can finish the welding thin plate again, or the direct current of doing the argon arc welding power source requirement is used arc welder more.
The purpose of above-mentioned utility model can reach by following scheme: " day " the shape iron core that falls of original DC arc welder transformer is made sphere of movements for the elephants shape iron core, be wound with winding and secondary close coupling winding at every phase upside of this iron core, downside is wound with secondary loose coupling winding, and secondary loose coupling winding is connected into head and the tail with secondary close coupling winding and connects.When sealing up the three-phase tail end of loose coupling winding in flakes with current switching, have little electric current output, when sealing up the three-phase tail end of close coupling winding in flakes, have big electric current output with switching.Finish the purpose of electric current coarse adjustment thus.The fine tuning of electric current is then finished by current regulating switch.
The utility model is compared with above-mentioned prior art can have following effect: since in the welding machine " day " font iron core become sphere of movements for the elephants shape iron core, and on iron core, add a secondary winding in addition.Change by the current switching terminal is cut, and makes arc welder can export big electric current, can export little electric current again, reaches a tractor serves several purposes.Because of adopting manual switchover can reduce cost in flakes.
Accompanying drawing 1 is DC arc welder general assembly inner shaft geodesic structure figure.
Accompanying drawing 2 is Fig. 1 transformer of arc welder iron core and winding construction figure.
Accompanying drawing 3 is that the another kind of Fig. 2 is implemented illustration.
Accompanying drawing 4 is electrical schematic diagrams of Fig. 1.
Accompanying drawing 5 is Fig. 1 arc-welding chassis shell front elevations.
Accompanying drawing 6 is Fig. 1 arc-welding chassis shell subsequent figures.
To be further described the utility model below in conjunction with accompanying drawing.The many compositions such as shell, voltmeter, ammeter, current regulating switch, current switching terminal, special transformer, rectifier, fin, reactor, power patch panel, welding output board, cooling fan that comprise with arc welder of this kind direct current.
As shown in Figure 5, voltmeter 3 is equipped with in the front of this machine shell 2, ammeter 4, current regulating switch 1, welding output board 5.As shown in Figure 6, this machine shell back side upside is equipped with the electric current coarse adjustment and switches binding post 14, and downside is equipped with power line terminal 13.Complete machine is supported by four iron tyres 6.As shown in Figure 2, transformer core 16 is formed the sphere of movements for the elephants type by silicon steel sheet.Comprising magnetic shunt silicon steel sheet 10, and be wound with winding 8 one time.Secondary close coupling winding 9 is around in the outside of a winding 8.Or as shown in Figure 3, a winding 8 is around in the outside of secondary close coupling winding 9, the common secondary winding of forming of connecting with secondary loose coupling winding 15.
Once whenever, extract seven taps mutually out, as shown in Figure 4, be connected to current regulating switch 1 respectively.By current regulating switch 1, receive power patch panel 13, be connected to by it and exchange 380 volts of power supplys of three-phase.As shown in Figure 4, the head end of the secondary loose coupling winding 15 of transformer is received the ac input end of rectifier bridge 20, and rectifier bridge 20 and fin 17 install to transformer core 16 upsides by support 7.Secondary loose coupling winding 15 tail ends are connected to the electric current coarse adjustment and switch binding post 14 upsides with after close coupling winding 9 head ends are connected.Secondary close coupling winding 9 tail ends are connected with coarse adjustment current switching binding post 14 downsides.When switching in flakes 18 when being connected to these switched terminal 14 upsides, have only 15 work of secondary loose coupling winding.At this moment the main flux by winding 8 generations is divided into two-way; One routing transformer iron core, 16 main bodys constitute the loop, and another road then constitutes magnetic shunt by silicon steel sheet 10.Thereby weakened magnetic flux, finished little electric current output by secondary loose coupling winding 15.
When switching in flakes 18 when moving on to current switching terminal 14 downsides, 9 one-tenth series relationship of secondary loose coupling winding 15 and secondary close coupling winding.Because the magnetic flux of winding 8 generations is all responded in secondary close coupling winding 9, so form big electric current output.The positive pole of rectifier bridge 20 is connected to the positive pole of welding output board 5, and negative pole connects an end of reactor 12.The other end of reactor 12 is connected to the negative pole of welding output board 5.The complete machine heat radiation is finished by ventilation blower 19.Angle steel 11 is used for clamping iron core, fixes as transformer.
Facts have proved with the many of this scheme making and following effect arranged with DC welder:
1, dynamic characteristic is good, and minimum current can be less than 15 peaces.
2, adopt the three phase full bridge rectification, add reactor, make output current more straight, splash and obviously improve.
3, general electric welding can be done, also argon arc welding power source can be made.
4, this machine is compared with homemade silicon rectifier ZXG-300 type (magnetic amplifier) welding machine, and cost is half of the latter.Old machine needs 6000-7000 unit, and this machine only needs about 3000 yuan.
Can design by this scheme and to produce series of products as 160,200,300,500 types etc. 120.
