Abstract
The utility model relates to a high frequency auxiliary power device for gas shield welding, mainly comprising an inverter output device (1), a high frequency transformer (4), a heater (5) and a wire feeder (6), wherein one end of the high frequency transformer (4) is connected with the inverter output device (1), while the other end is connected with the heater (5) and the wire feeder (6); the inverter output device (1) is further connected with a welding transformer (3) simultaneously; and a relay (2) is further positioned between the inverter output device (1) and the welding transformer (3). The device of the utility model has the following advantages: by adopting a high-voltage variable frequency transformer to supply power, volume of a heating power transformer is reduced to 1/3 of the former volume and weight is 1/4 of the former weight, thereby greatly benefiting miniaturization and portable carrying design of an integral gas shield welding machine, and ensuring the product to use more conveniently.
Description
Technical field
The utility model relates to a kind of carbon dioxide gas arc welding that is used for and connects the heating power supply device on the pressure-reducing valve.
Background technology
Carbon dioxide gas arc welding connects the pressure-reducing valve heating power supply; Be called for short gas guarantor weldering pressure-reducing valve and need heating work; The heating power supply index is AC36V 150w～250w, and routine heating power supply mode is: adopt AC transformer, directly gas is protected weldering main frame voltage supplied 380V and become interchange AC36V; Because it is bigger to reach the Industrial Frequency Transformer volume weight of this standard, be unfavorable for operation.
The utility model content
The technical problem that the utility model will solve provides the heater on a kind of suitable bonding machine, particularly a kind of heating power supply device.
The primary structure characteristics of the utility model are: mainly be made up of inversion output device, high frequency transformer, heater, wire-feed motor; Its high frequency transformer one end is connected with the inversion output device; The other end links to each other with heater, wire-feed motor; Its inversion output device also links to each other with a welding transformer simultaneously, between its inversion output device and the welding transformer relay is set also.
The beneficial effect of the utility model is: adopt the high-pressure frequency-conversion transformer-supplied; It is original 1/3rd that the heating power supply volume of transformer can be contracted to, and weight is original 1/4th, is beneficial to gas greatly and protects the miniaturization of weldering complete machine; Light carry design, make product more convenient to use.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details
Fig. 1 is the utility model product structure sketch map
The specific embodiment
Referring to shown in Figure 1; Gas is protected weldering high frequency auxiliary power unit; Mainly be made up of inversion output device 1, high frequency transformer 4, heater 5, wire-feed motor 6, its high frequency transformer 4 one ends are connected with inversion output device 1, and the other end links to each other with heater 5, wire-feed motor 6; Its inversion output device 1 also links to each other with a welding transformer 3 simultaneously, and a relay 2 also is set between its inversion output device 1 and the welding transformer 3.
When welding, relay 2 breaks off, and welding transformer 3 is not worked, and inversion output device 1 voltage adds on the high frequency transformer 4, produces 36V high-frequency heating voltage, supplies with heater 5.
During welding, relay 2 adhesives, the inversion output device is supplied with welding transformer 3 and high frequency transformer 4. simultaneously
When welding was interrupted, of short duration stopping to appear in inversion output device 1, and relay 2 breaks off, and to prevent to produce arcing, the moments later inversion of delaying time output recovers high frequency transformer 4 normal power supplies.
Utilize the high frequency voltage of inversion major loop cleverly, divide the electrical power of 150w～250w to give heater 5, realized continuous heating.
Claims (1)
