Description
Technical field
The utility model relates to a kind of electric welding machine.
Background technology
The basic functional principle of electric welding is us by the 220V voltage of commonly using or the commercial power of 380V, reduced voltage by the pressure reducer in the electric welding machine, strengthened electric current, and made electric energy produce huge electric arc heat to melt iron and steel, and welding rod to incorporate the amalgamation that makes between the iron and steel higher.Arc welding is present most widely used welding method, and it includes: manual metal-arc welding, submerged-arc welding, shielded arc welding of tungsten electrode gas, plasma arc welding (PAW), gas metal-arc welding etc.
Manual metal-arc welding be in the various arc welding methods development the earliest, present most widely used a kind of welding method still.It is to make electrode and fill metal with the welding rod that the outside scribbles coating (coating), and electric arc is to burn between the end of welding rod and welded piece surface.Coating (coating) can produce gas on the one hand with protection electric arc under the arc heat effect, can produce on the other hand slag and cover weld pool surface, prevents that the interaction of molten metal and ambient gas from generating oxide; The more important function of slag is to produce physical-chemical reaction or add alloying element with the deposite metal, improves the weld metal performance.Manual metal-arc welding equipment is simple, light, flexible operation, and the welding of the short seam in can being applied to keep in repair and assemble particularly can be used for the welding at unapproachable position.The corresponding welding rod of manual metal-arc welding adapted is applicable to most industry carbon steel, stainless steel, cast iron, copper, aluminium, nickel and alloy thereof.
Now common manual arc welder mainly contains DC welder and AC welding set on the market, wherein disposes transformer and rectification module in the DC welder, during the alternating current input, after the transformer transformation, again by rectifier rectification, is output as the direct current of low-voltage, high-current.The output current of existing hand arc DC welder when work is no less than 160A, needing when electric current amplifies to carry out larger no-load voltage ratio, to the requirement of transformer more coil around the home, cause the volume of welding machine large, weight is large, is inconvenient to carry, existing a kind of small-sized hand arc DC welder weight is all at 5.5Kg, profile is made spacious chest shape for the ease of heat radiation, volume is larger, than being easy to carry and carrying, can not directly grab in hand simultaneously and use.
Summary of the invention
In order to solve the problem that existing hand arc electric welding machine volume is large, weight large, be not easy to carry, the purpose of this utility model is to provide a kind of light clutch type electric welding machine.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of light clutch type electric welding machine, comprise housing, be provided with rectification module, radio-frequency generator, transformer and secondary rectification module in the described housing, described secondary rectification module output connects soldering turret, described housing is strip, and the thickness of housing is grabbed with the expert and is as the criterion.
Direct current after light clutch type electric welding machine of the present utility model adopts first radio-frequency generator with rectification is converted to high-frequency pulse current, improves current value by transformer again, and then carries out exporting after the secondary rectification.Contrast the electric welding machine of existing single flow, the design is owing to adopting high-frequency pulse current to carry out transformation, to transformer require low, therefore, the transformation body that the transformer that adopts among the design contrasts the electric welding machine of existing single flow has little, the lightweight advantage of volume, thereby reduce electric welding machine volume and weight of the present utility model, electric welding machine is easy to carry, and be applicable to hand and grab use.
Further, the connected mode of soldering turret and housing is optional, and soldering turret can be directly installed on the housing or by cable and be connected on the housing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the outline drawing of a kind of embodiment of the utility model;
Fig. 2 is the outline drawing of another embodiment of the utility model;
Fig. 3 is electrical principle block diagram of the present utility model.
The specific embodiment
Referring to figs. 1 through Fig. 3, a kind of light clutch type electric welding machine that the utility model provides comprises housing 1, and housing 1 is preferably strip, and its size is grabbed with the expert and is as the criterion; Be provided with rectification module 3, radio-frequency generator 4, transformer 5, secondary rectification module 6 and control module 7 in the housing 1, rectification module 3 can be full-wave bridge rectifier circuit, is used for alternating current is converted to direct current; Radio-frequency generator 4 is MOSFET FET circuit or IGBT insulated gate bipolar transistor circuit, for generation of the high-frequency impulse waveform; Transformer 5 is step-down transformer; Secondary rectification module 6 is used for the electric current after the transformation is carried out the secondary rectification; Control module 7 is a singlechip chip or PLC chip and peripheral circuit thereof, according to the waveform shape of the programme-control high-frequency impulse waveform of inputting in the chip.In the utility model, rectification module 3, radio-frequency generator 4, transformer 5, secondary rectification module 6 connect successively, the input of rectification module 3 connects power supply, the output of secondary rectification module 6 connects soldering turret 2, the output of control module 7 connects radio-frequency generator 4, the output of the input connecting secondary rectification module 6 of control module 7 is used for receiving the output current that feeds back and the waveform shape of adjusting the high-frequency impulse waveform according to feedback circuit.Further, soldering turret 2 is optional with the connected mode of housing 1, and as shown in Figure 1 and Figure 2, soldering turret 2 can be directly installed on the housing 1 or by cable and be connected on the housing 1, and soldering turret 2 is used for clamping welding rod, is used for simultaneously the conducting welding rod.
Direct current after light clutch type electric welding machine of the present utility model adopts first radio-frequency generator with rectification is converted to high-frequency pulse current, power frequency after the conversion can be up to 100KHz, high-frequency pulse current improves current value by transformer 5, then by exporting after the secondary rectification.Contrast the electric welding machine of existing single flow, the design is owing to adopting high-frequency pulse current to carry out transformation, greatly reduce the requirement to transformer 5, therefore, the transformation body of the electric welding machine of the existing single flow of transformer 5 contrasts that adopts among the design has little, the lightweight advantage of volume, thereby reduces the volume and weight of electric welding machine.
Electric welding machine weight of the present utility model is about 1.5Kg, and the weight of existing small-sized hand arc-welding machine is 5.5Kg.Existing small-sized hand arc-welding machine can not directly be grabbed and use on hand because its volume of transformer is large, and the volume of complete machine is also large; And clutch type electric welding machine of the present utility model has adopted more small-sized inner member, and its shell 1 thickness can be set to be suitable for hand and grab use, and when soldering turret 2 was directly installed on the shell 1, the user can directly grab welding machine in hand and use.
The above only is preferential embodiment of the present utility model, but the utility model is not limited to above-mentioned example, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the present utility model.
