Abstract
The utility model relates to welding equipment, in particular to a high frequency arc striking discharger of a welding machine. The utility model aims to provide a high frequency arc striking discharger of a welding machine with the advantages of small size and convenient replacement; therefore, the high frequency arc striking discharger of the welding machine comprises a cylindrical insulating base; two electrodes are connected at the two ends of the insulating base respectively; a certain distance is formed between the two ends of the insulating base where the electrodes are arranged, and the two end surfaces are parallel to each other; and two tungsten electrodes are connected at the two ends of the insulating base where the electrodes are arranged. Due to the adoption of the technical scheme, the utility model is smaller in size than the prior dischargers. The discharger can be mounted very conveniently even on a mini inverter welding machine, and can be mounted on the welding machine by taking the fuse holder as the bracket without using retaining screws or connecting wires; and moreover, the discharger can be mounted and replaced directly and more conveniently.
Description
Technical field
The utility model relates to welding equipment, specifically, relates to a kind of electric welding machine high-frequency arc strike discharger.
Background technology
In the welding machine field, high-frequency arc strike is a kind of starting the arc mode, is usually used in argon arc welding machine, plasma welding machine, CUT.So-called " high frequency " produces by discharger, and about 3000V, this voltage is added between electrode and the workpiece its frequency at 2-3KHz, DC voltage, punctures the air electric arc that ignites.Therefore discharger is most important in the high frequency starting the arc, in case lost efficacy, welding machine just can't be set up electric arc.There is following problem in existing discharger: volume is big, is inconvenient to install when being used for small-sized inverter type welder; Change inconvenience, existing discharger need be pulled down the fixed screw and the connecting line of discharger when changing, both time-consuming, the effort of taking a lot of work again.
Summary of the invention
The purpose of this utility model provide a kind of volume little, change convenient and adjustable electric welding machine high-frequency arc strike discharger.
In order to achieve the above object, the utility model electric welding machine high-frequency arc strike discharger, comprise: a columniform insulator foot, respectively connect an electrode at these insulator foot two ends, have certain distance and both ends of the surface to be parallel to each other between the two ends of described electrode in insulator foot, described electrode connects a tungsten electrode respectively on the two ends in insulator foot.
Wherein, above-mentioned electrode is bolted on the insulator foot; Described tungsten electrode is bolted in the described copper electrode, and the end that described electrode exposes insulator foot is provided with the adjusting mouth; Described insulator mount adopts teflon to make; A peep hole is respectively established at described insulator mount middle part, and the position of described peep hole is over against described tungsten electrode.
The utility model makes it compared with prior art owing to adopted above-mentioned technical scheme, has following advantage and good effect:
1. the utility model makes that the more existing discharger of volume is littler owing to adopted said structure, even if also very convenient when being installed in small-sized inverter type welder;
2. the utility model is a support with the Insurance Block of electric welding machine, can directly be mounted thereon, and does not need to use fixed screw and connecting line, can directly install, change, and is more convenient.
Description of drawings
To embodiment of the present utility model and in conjunction with the description of its accompanying drawing, can further understand the purpose of this utility model, specific structural features and advantage by following.Wherein, accompanying drawing is:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model insulator foot.
Fig. 3 is the circuit theory diagrams of electric welding machine work.
The specific embodiment
The utility model electric welding machine high-frequency arc strike discharger as shown in Figure 1, comprise a columniform insulator foot 1, respectively connect an electrode 21,22 at insulator foot 1 two ends, electrode 21,22 has certain distance and both ends of the surface to be parallel to each other between the two ends in insulator foot 1, connects a tungsten electrode 31,32 on the two ends of electrode 21,22 in insulator foot 1 respectively.Wherein, electrode 21,22 is bolted on the insulator foot 1, and tungsten electrode 31,32 is bolted in the electrode 21,22, and the end that electrode 21,22 exposes insulator foot 1 is provided with regulates mouth 41,42; Insulator mount 1 adopts teflon (Teflon) to make, and a peep hole 11,12 (as shown in Figure 2) is respectively established at insulator mount 1 middle part, and the position of peep hole 11,12 is over against tungsten electrode 31,32.
The utility model electric welding machine high-frequency arc strike discharger is installed on the Insurance Block of welding machine, Insurance Block be support be again the high pressure coupler, can change distance between the tungsten electrode 31,32 by the adjusting mouth 41,42 of regulating electrode 21,22 ends, thereby regulate the frequency and the size of high-frequency arc strike voltage, distance is big, voltage height but frequency is low; Distance is little, then voltage low frequency height.Arcing distance is generally regulated between 0.5 to 2 millimeter.In conjunction with shown in Figure 3, about 3000 volts of high pressure, charge to discharge capacity through winding of high-frequency coupler to a pair of tungsten electrode 31,32 through electrode 21,22 simultaneously, and when the voltage of charging capacitor reached the breakdown voltage of discharger, electric capacity discharged through discharger.The capacitor charge and discharge electric current forms the striking high pressure through high-frequency coupler between welding gun and workpiece.
Though the utility model is illustrated hereinbefore according to preferred embodiment, this does not represent that scope of the present utility model is confined to above-mentioned structure, if by structure that claim of the present utility model covered all within protection domain.Those skilled in the art can be developed the equivalent substitution structure that at an easy rate after reading above-mentioned explanation, in following equalization variation and the modification of being done of spirit that does not break away from the utility model and scope, all should be covered by within the utility model claim.
