Description
Technical field
The present invention relates to start employed high frequency input coupling coil in the arc welder of arc discharge and this arc welder by the high frequency generating mode.
Background technology
In the past, there were the electric discharge phenomena utilized to carry out the arc welder of metal solder.Arc welder produces arc discharge between mother metal and electrode, utilize the heat that is produced by arc discharge that mother metal is melted, and welds.When beginning to produce arc discharge, need cause insulation breakdown in the electric field strength that generates more than the defined value between mother metal and the electrode.As the method that is used for insulation breakdown, when starting arc welder, the high frequency generating mode that adds the high frequency voltage that is generated by high frequency generating apparatus between mother metal and electrode is known.
Fig. 8 is the key diagram of an example of the arc welder of high frequency generating mode.Arc welder 100 has: the supply unit 200 that is provided for the power of arc discharge; When beginning to produce arc discharge, generate the high frequency generating apparatus 300 of high frequency voltage; And the coupling coil 400 that is used to make the direct voltage stack that high frequency voltage that high frequency generating apparatus 300 provided and supply unit 200 provided.
Arc welder 100 is when arc discharge begins, start supply unit 200, between mother metal 500 and electrode 600, add the direct voltage (voltages of for example several 10 " V ") of low-voltage, then, by starting high frequency generating apparatus 300, superposeing on this direct voltage, (for example, the voltage of thousands of～tens thousand of " V ") high frequency voltage produces insulation breakdown to high voltage between mother metal 500 and electrode 600.
Fig. 9 is the key diagram of an example of coupling coil in the past.Coupling coil 400 has: the connected primary coil 401 of pair of output of high frequency generating apparatus 300; Be connected in lead-out terminal of supply unit 200 and the secondary coil 402 between the electrode 600; Form the core 403 of primary coil 401 and secondary coil 402.Coupling coil 400 will be input to the high frequency voltage of primary coil 401, boost to and the corresponding high-tension high frequency voltage of the turn ratio of primary coil 401 and secondary coil 402, export to secondary coil 402 1 sides.The high frequency voltage that high frequency generating apparatus 300 is generated is boosted by coupling coil 400, then with the direct voltage stack of exporting from supply unit 200.By the very high high frequency voltage of stack on direct voltage, the insulation between mother metal 500 and the electrode 600 is destroyed, produces arc discharge.Thus, between mother metal 500 and electrode 600, form current path, the direct current power of welding usefulness is provided from supply unit 200.
After producing arc discharge, owing between mother metal 500 and electrode 600, there is no need applying high-frequency voltage, therefore, high frequency generating apparatus 300 is stopped, only the direct current power that provides by supply unit 200 continues arc discharge,, welds mother metal 500 fusings by this heating.If high frequency generating apparatus 300 is stopped, the number 10V that can descend of the potential difference between mother metal 500 and the electrode 600 then, therefore, and in electric arc welding process, the high electric current of hundreds of A that between mother metal 500 and electrode 600, flow.For example, be under the situation of 400A at the output current of arc welder 100, connect the electric current of the 400A that flows in the connecting line of supply unit 200 and electrode 600.
Therefore, the secondary winding 402a of the secondary coil 402 of formation coupling coil 400 also needs to use the wire rod that can flow through the above electric current of 400A.In addition, under the situation of using jumbo wire rod, because caloric value is big, so, also need secondary winding 402a to be set to suppress as much as possible the structure that temperature rises in order to increase the specified utilization rate of arc welder 100 as far as possible.Therefore, in the example of Fig. 9, as secondary winding 402a, adopt following structure, that is, use the electric wire (being generally copper cash) of the material that area of section is big, resistivity is low, on the leg (leg of upside among Fig. 9) of core 403, the interval of defined is set, this electric wire is rolled into helical form.
Patent documentation 1:JP opens flat 5-46014 communique in fact
But, under the situation of the area of section that increases secondary winding 402a, exist the size of coupling coil 400 to become big problem.For example, when the material of secondary winding 402a is under the situation of copper, in order to flow through the electric current of 400A, need be set to more than the 10mm by diameter, if also comprise insulating coating, then diameter is more than the 13mm.Compare with aluminium etc., the pliability of copper is low, and diameter becomes conference and causes pliability further to reduce.Therefore, can not make this secondary winding 402a be close to core 403 and reel, it is big that the diameter of secondary coil 402 becomes.On the other hand, be under the situation of aluminium at the material of secondary winding 402a, the resistivity of aluminium is about 1.6 times of resistivity of copper, therefore, diameter need be made as about 1.6 times under the situation of copper.Though the pliability of aluminium than copper height, causes pliability to reduce because diameter becomes conference, therefore, the diameter that this secondary winding 402a is wound on the secondary coil 402 on the core 403 becomes bigger, and the length that is rolled into spiral helicine secondary winding 402a is also elongated.
In addition, the secondary winding 402a of secondary coil 402 and the interval of core 403 become greatly, simultaneously, need to consider that heat radiation be provided with spiral intervals (pitch), and therefore, leakage flux increases, in the high frequency voltage reduction of secondary winding 402a side induction.Therefore, in order to be made as the high voltage of defined, need to increase the number of turn at the high frequency voltage of secondary winding 402a side induction.Because it is big that the diameter of secondary coil 402 becomes, and need the increase number of turn, therefore, secondary coil 402 becomes big, comprises its coupling coil 400 whole changes greatly.
In addition, though in the example of Fig. 9, shown and used the coupling coil 400 that is seen as the core 403 of hollow from the front, but, also the someone has proposed following formation, promptly, on same bobbin with helical coil around primary coil and secondary coil, insert iron core (with reference to patent documentation 1) in the inside of bobbin.By this formation, owing to be that primary coil and secondary coil are configured on the identical axle, therefore, compare with the example of Fig. 9 that primary coil and secondary coil are disposed side by side, the compact in size of the short transverse among this figure still need can be provided with the heat resistant structure at the heating of secondary coil on primary coil.Therefore, as coupling coil on the whole, it is big that the diametric(al) of bobbin or the size of length direction become, and miniaturization and densification are subjected to certain restriction, and this point is identical with the example of Fig. 9.
Summary of the invention
The present invention considers above-mentioned technical task and finds out, its objective is: provide a kind of can be in the big arc welder of output current coupling coil that use, that reduced the diameter of secondary coil.
In order to solve above-mentioned technical task, the present invention has adopted following technological means.
The feature of the coupling coil that provides by the 1st aspect of the present invention is as follows, that is, have: secondary winding, and it is transfused to the processing power that adopts arc discharge from supply unit; With elementary winding, itself and this secondary winding magnetic coupling, and be input for producing the high frequency voltage of above-mentioned arc discharge.After above-mentioned coupling coil boosted above-mentioned high frequency voltage, with the voltage stack that is applied to from above-mentioned supply unit on the above-mentioned secondary winding, above-mentioned secondary winding was a bonding jumper, is wound up on the above-mentioned core with the roller shape with insulating trip.
In preferred implementation of the present invention, above-mentioned bonding jumper is a copper bar.In addition, in other preferred implementations, the electric wire that conductor terminal is used is fixed on the above-mentioned secondary winding, and said wires is a copper litz wire.

According to coupling coil of the present invention,, therefore, under situation about for example being wound on the core, can be close to this core and reel as the secondary winding pliability height of bonding jumper.Therefore, be rolled into spiral helicine situation with metal wire with the identical number of turn and compare, can reduce the diameter that secondary winding is rolled into the secondary coil of roller shape the same cross-sectional area.In addition, reeled,, can be suppressed at the reduction of the high frequency voltage of secondary winding side induction so leakage flux reduces because secondary winding is close to core.Therefore, be rolled into spiral helicine situation with metal wire and compare, can reduce the number of turn of secondary winding the same cross-sectional area.Thus, be rolled into spiral helicine situation with metal wire and compare, can dwindle secondary coil the same cross-sectional area.
In addition, because the pliability height of secondary winding, so, even under the little situation of the cross section of core face girth, also secondary winding can be close to coiling.Therefore, can further dwindle the diameter of secondary coil.Because can dwindle secondary coil, thus the size of whole core also can be dwindled, thus can dwindle whole coupling coil.In addition, because the miniaturization of core has reduced cost, also can reduce the amount of the metal material that is used for secondary coil.
Core is being made under the bar-shaped situation, compared, can realize the miniaturization of core, can dwindle coupling coil more with see the core that is square shape from the front.In addition, under the situation on the same position that elementary winding and secondary winding is wound onto core, the coupling that can improve elementary winding and secondary winding, so, the reduction of the high frequency voltage of secondary winding side induction can be suppressed at, thereby the number of turn of secondary winding can be suppressed.
Being characterized as of the arc welder that provides by the 2nd aspect of the present invention: have the coupling coil that the 1st aspect of the present invention is provided.
According to this formation, owing to coupling coil is miniaturized, so also can realize the miniaturization of arc welder.

Embodiment
Below, with reference to accompanying drawing embodiments of the present invention are specifically described.
Fig. 1 and Fig. 2 are the key diagrams of an example of the 1st execution mode of coupling coil of the present invention.Fig. 1 is the stereogram of coupling coil 1, and Fig. 2 is the profile along the II-II line of Fig. 1.As shown in Figure 1, coupling coil 1 has primary coil 11, secondary coil 12, core 13.After coupling coil 1 will boost by the high frequency voltage that high frequency generating apparatus 300 generates, make it be added to mother metal 500 and electrode 600 between direct voltage superpose (with reference to Fig. 8).In addition, in Fig. 1 and Fig. 2, in order to map conveniently, the number of turn of secondary coil 12 is compared with material object, simplifies in the description, among the Fig. 4 that mentions later, Fig. 6, Fig. 7 too.
In addition, in the present embodiment,, be not limited to this though use copper bar as secondary winding 121.It for example also can be the bonding jumper that aluminium or the low Metal Forming of silver-colored constant resistance rate are become band.In addition, the size of copper bar can suitably be set according to each size, the number of turn of the secondary winding coiling 13b of portion of the core 13 of reeling and the electric current that flows through.In the present embodiment, width dimensions is made as 70mm, gauge is made as 1.2mm according to the left and right directions size L in Fig. 1 of the secondary winding coiling 13b of portion, can be so that form by area of section (about 84mm of 400A electric current
2).In addition, for around the secondary winding coiling 13b of portion (the rectangular girth 120mm in cross section of the secondary winding coiling 13b of portion among Fig. 2) with insulating trip 123 8 circles of reeling, length dimension is made as about 1410mm.
2 wire 122a, 122b are respectively the copper litz wire of tape insulation coating, and the insulating coating of an end is removed, and are fixed on the both ends of length direction of a face (upper side among Fig. 3) of secondary winding 121.With electric wire 122a, 122b make copper litz wire be because: can by the welding be fixed at an easy rate on the secondary winding 121, and when the secondary winding 121 after will having fixed 122a, 122b is wound on the secondary winding coiling 13b of portion of core 13, can not make the interval between core 13 and the secondary winding 121 become big (with reference to Fig. 2).In addition, also because electric wire 122a, 122b bring into play the function as the lead of secondary coil 12, so, by being made as copper litz wire, can make lead have flexibility.And, though electric wire 122a, 122b are not limited to copper litz wire,, if common copper cash then need be worked hard on fixing means, also need to try every possible means to make core 13 and the interval between the secondary winding 121 when reeling can not become big.
In the present embodiment, though the face that electric wire 122a, 122b are fixed as the inboard, the secondary winding coiling 13b of portion that secondary winding 121 is wound on core 13 goes up (with reference to Fig. 2), also this face can be reeled as the outside.In addition, also electric wire 122a and electric wire 122b can be separately fixed on the face that differs from one another of secondary winding 121.In addition, electric wire 122a and electric wire 122b can also be separately fixed on two end faces of length direction of secondary winding 121.In this case, therefore electric wire 122a and electric wire 122b, can dwindle the interval between core 13 and the secondary winding 121 during owing to coiling not between core 13 and secondary winding 121.
In the present embodiment, electric wire 122a, 122b being fixed on the Width (lower-left among Fig. 3 is to upper right direction) of whole secondary winding 121 is in order to improve constant intensity, and makes electric current flow through whole secondary winding 121 equably.And, under the little situation of the area of the stationary plane of electric wire 122a, 122b and secondary winding 121, the resistance value of stationary plane uprises, might be fused owing to generate heat, therefore, the area that should make stationary plane greater than with the area of section (hereinafter to be referred as " area of section of secondary winding 121 ") of the length direction quadrature of secondary winding 121.
In the present embodiment, though when carrying out arc welding, owing in electric wire 122a, 122b, flow through for example high electric current of 400A, therefore the area of section with conductor part is made as 84mm2, but the area of section of electric wire 122a, 122b, diameter, material, kind can suitably be set according to the electric current that flows.
Another end of electric wire 122a is connected with the supply unit 200 of arc welder 100, and another end of electric wire 122b is connected (with reference to Fig. 8) with the electrode 600 of arc welder 100.Therefore, formed, arrived the current path of electrode 600 via electric wire 122a, secondary winding 121, electric wire 122b from supply unit 200.When arc welder 100 started, after coupling coil 1 will be boosted by the high frequency voltage that high frequency generating apparatus 300 provides, and the direct voltage that is applied between mother metal 500 and the electrode 600 from supply unit 200 superposeed.In addition, when carrying out the welding operation of arc welder 100, the secondary coil 12 of coupling coil 1 becomes from the path of current of supply unit 200 outputs.
As shown in Figure 2, when insulating trip 123 is used on the secondary winding coiling 13b of portion that secondary winding 121 is wound on core 13, prevents secondary winding 121 short circuits, and be wound on the secondary winding coiling 13b of portion with secondary winding 121.In the present embodiment,, be not limited to this, can use the resinousness sheet of polyimide resin or heat-resistant polyvinyl chloride resin etc., also can use fibrous paper etc. though use the aromatic polyamide resin sheet as insulating trip 123.
Next, the effect to coupling coil 1 describes.
In the present embodiment, use copper bar as secondary winding 121.This copper bar is 1.2mm owing to gauge, the pliability height, and the secondary winding coiling 13b of portion that therefore can be close to core 13 reels.Therefore, be rolled into spiral helicine situation with copper cash with the identical number of turn and compare, can reduce the diameter of secondary coil 12 the same cross-sectional area.In addition, in the present embodiment, because the secondary winding 121 of copper bar is close to the secondary winding coiling 13b of portion is rolled into the roller shape, therefore, can not produce the gap in the helical coil of copper cash, so, compare with helical coil, leakage flux reduces, thereby can suppress to offer the reduction of the high frequency voltage of secondary winding 121 1 sides.Therefore, be rolled into spiral helicine situation with copper cash and compare, can reduce the number of turn of secondary winding 121 the same cross-sectional area.Thus, be rolled into spiral helicine situation with copper cash and compare, can dwindle secondary coil 12 the same cross-sectional area.
And, though the central opening to core 13 in Fig. 1 has partly carried out amplifying expression, but in the product of reality, this opening portion can narrow down to primary coil 11 and the not contacted degree of secondary coil 12, so the size of core 13 becomes and also wants miniaturization than the example of Fig. 9, therefore, magnetic circuit is miniaturization also, so, can reduce leakage flux.That is, the mutual inductance of primary coil 11 and secondary coil 12 can be increased, good coupling can be carried out.
In addition, because the pliability height of secondary winding 121, so, also secondary winding 121 can be close to the secondary winding coiling 13b of portion and reel even under the situation of the secondary winding coiling 13b of portion of core 13 thin (cross section face girth is little).Therefore, can further dwindle the diameter of secondary coil 12.
Owing to can dwindle secondary coil 12,, can dwindle whole coupling coil 1 so also can dwindle the size of whole core 13.In addition, can also make arc welder 100 miniaturizations with coupling coil 1.
In addition, by with core 13 miniaturizations, also reduced the amount of the copper product that is used for secondary coil 12, thereby can reduce the cost of coupling coil 1.
In above-mentioned the 1st execution mode,, also can on adjacent leg, form respectively though the situation that forms primary coil 11 and secondary coil 12 on the opposed leg of core 12 respectively is illustrated.In addition, primary coil 11 and secondary coil 12 can also be formed on the identical leg of core 13.In this case, as shown in Figure 4, by elementary winding 11a is wound on secondary coil 12 around, can make the winding position at leg of primary coil 11 and secondary coil 12 identical.
In Fig. 4, the key element to identical or similar with coupling coil shown in Figure 11 has marked same reference numeral.The coupling coil 1 ' of the 2nd execution mode shown in Figure 4 and the 1st execution mode difference be, by elementary winding 11a is wound on secondary coil 12 around, primary coil 11 and secondary coil 12 are formed on the same position of core 13.And, in the coupling coil 1 ' of the 2nd execution mode, for elementary winding 11a is fused because of the heating of the big electric current generation of flowing through secondary winding 121, elementary winding 11a is made as the heat resisting temperature electric wire also higher than the electric wire of the 1st execution mode, or secondary winding 121 is made as with the electric wire of the 1st execution mode compares, area of section is bigger, and resistance is littler.
In the 2nd execution mode, owing to the pliability height of secondary winding 121, can dwindle the diameter of secondary coil 12, can bring into play the action effect identical with the 1st execution mode.In addition, because therefore the elementary winding 11a that reels on secondary winding 121, can reduce leakage flux.
In addition, as the method for winding of elementary winding 11a and secondary winding 121, can be opposite with Fig. 4, elementary winding 11a is wound on the core 13 secondary winding 121 of reeling in the above then earlier.In addition, also can be between the secondary winding 121 that is wound on the core 13, the elementary winding 11a that reels, thereby integrally formed primary coil 11 and secondary coil 12.

In the 3rd execution mode, also because the pliability height of secondary winding 121, and can dwindle the diameter of secondary coil 12, can bring into play the action effect identical with the 1st execution mode.And, because core 13 ' is bar-shaped, so can dwindle the size of the above-below direction among Fig. 6.
In the 3rd execution mode, though consider the heating in the secondary coil 12, with primary coil 11 and secondary coil 12 alignment arrangements on core 13 ', but, as mentioned above, if the heating countermeasure to elementary winding 11a or secondary winding 121 enforcement secondary coils 12 then as shown in Figure 7, also can be wound on elementary winding 11a on the secondary coil 12 overlappingly.
