Abstract
The invention discloses a portable multifunctional double-wire self-protecting flux-cored wire welding device, consisting of a welding wire pinching mechanism, a handheld welding gun body and portable IGBT double-wire welding inverted power source. The welding wire pinching mechanism is an integrally-arranged self-protecting flux-cored wire double-wire feeding mechanism which can feed wires smoothly and consists of two pairs of wire feeding wheels and wire feeding tubes. The device has the advantages of portability, high efficiency, strong anti-interference ability, good cooperativity, and the like and ensures stable double-wire welding process, attractive welding line molding and high welding quality.
Description
Affiliated technical field
The invention belongs to welder, especially be applied to double-wire self-protecting flux-cored wire welding device and make the field.
Background technology
The monofilament that is used for adopting when the heavy construction member is repaired welds the wayward and adjusting of metallurgical quality, and the soldering layer is easy to generate defectives such as crackle, and weld job efficient is lower, is difficult to satisfy the needs of efficient welding.In order to solve problems such as postwelding cold crack, developed the flux-cored wire Double Wire Welding, this technology not only can improve operating efficiency, and can proof stress and distortion.Can form the circulation of favourable long narrow temperature field and double quotidian fever when the medicine wire bond connects double wire welding, can reduce the maximum temperature in molten bath, reduce degree of superheat and heat affected area width, improve the toughness of heat affected area, the t when also increasing the molten bath cooling
8/5, the former can improve the structure property of weld seam, and the latter can reduce the crackle tendency.Preceding in addition welding wire plays preheating and bottoming, and back welding wire rises adjusts composition and back heat effect.These advantages of medicine wire bond silk double wire welding especially are suitable for the online reparation of rail.But therefore the structure that present Double Wire Welding equipment adopts mariages to carry respectively exists inconvenience in the use.
Summary of the invention
In view of the above shortcoming of prior art, the objective of the invention is to design a kind of portable double-wire self-protecting flux-cored wire welding device, make it to overcome the above shortcoming of prior art.
The objective of the invention is to realize by following means.
A kind of portable multifunctional double-wire self-protecting flux-cored wire welding device; form by welding wire pinch mechanism, portable welding gun rifle body and portable type IGBT Double Wire Welding inverter; it is characterized in that; the wire feed of the integrated setting of described welding wire pinch mechanism is self-protection flux-cored wire mariages wire feeder smoothly, and self-protection flux-cored wire mariages wire feeder is made of two pairs of wire feed rolls and wire convey soft pipe.
Advantages such as equipment of the present invention has light, and is efficient, and antijamming capability is strong, and concertedness is good, the Double Wire Welding welding process is stable, and appearance of weld is attractive in appearance, the welding quality height.

Fig. 2 is the front view of wire feed rolls of the present invention.
Fig. 3 is an embodiment mechanism vertical view of distance between weldingwires governor motion
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Welding machine of the present invention with the supporting use of portable type IGBT Double Wire Welding inverter.As shown in Figure 1, portable multifunctional double-wire self-protecting flux-cored wire welding device, 1. flux-cored wire; 2. welding wire pinch mechanism; 3. portable welding gun rifle body; 4. ignition tip; 5.IGBT the hand-held arc welding gun head that Double Wire Welding inverter 6. flight leads are adjustable 7. welds two molten baths, 8. soldered rail.The wire feed of the integrated setting of welding wire pinch mechanism is self-protection flux-cored wire mariages wire feeder smoothly, and self-protection flux-cored wire mariages wire feeder is made of two pairs of wire feed rolls 2.For the protection flux-cored wire is not stressed destruction, all has U-lag 9 as shown in Figure 2 on each wire feed rolls.Flexible pipe can be connected between wire feeder and the welding gun rifle body, flux-cored wire passes through in managing, and smooth and easy to guarantee the flux-cored wire wire feed, flux-cored wire wire feed diameter range is φ 1.2～φ 2.0.Can realize parallel and serial arrangement between two welding wires.Be provided with the distance between weldingwires governor motion of the spacing that is used to regulate two welding wires near the ignition tip, generally can adopt bolt chute structure, Fig. 3 is an embodiment: wherein a welding wire is worn and is attached on the bolt 10 with perforation, and bolt can move and be fixed on select location along near the chute 11 the ignition tip 4, like this, the spacing of two welding wires can be adjusted in the 10-40mm scope, to realize that two welding wires front and back serials are total to the process conditions of bath and the two kinds of functions in not congruent melting of serial pond, in welding gun, can realize parallel sending to for two before and after during use, and two root bead silk smooth combustions in the time of can guaranteeing to weld, welding gun is light hand-holdable, collaborative matching is good between the dual power supply, strong interference immunity, equipment is light, is particularly suitable for the field construction field operation.The Double Wire Welding welding process is stable, and appearance of weld is attractive in appearance, the welding quality height.
