Detailed description of the invention
As shown in Fig. 1, the double wire feeder of the list source of welding current of the present invention, including a source of welding current 1, wire-feed motor frame 2, two set wire feeder, permutator control circuit and protective gas air supply system；Described two set wire feeders are arranged in wire-feed motor frame 2；The binding post of the described source of welding current 1 is in addition to including welding torch cable 5 binding post, mother metal cable 6 binding post and the first data wire 7 binding post, from the internal control circuit plate of the source of welding current 1, also draw the binding post of the second data wire 8, being divided into two branch roads in parallel respectively two set wire feeder in the middle of the welding torch cable 5 of described welding torch cable 5 binding post output to power, the first data wire 7 and the second data wire 8 connect two set wire feeders respectively；Described permutator control circuit and source of welding current circuit board 14 constitute loop；The trachea 9 of protective gas air supply system is divided into two parallel branches and is respectively two set wire feeder supply.
Described two set wire feeders include that first 32, two welding guns of wire-feed motor the 31, second wire-feed motor, two set wire-feeding pipes and supporting welding torch cable and trachea, two welding guns are connected with the first wire-feed motor 31 and the second wire-feed motor 32 by two set wire-feeding pipes respectively.
As shown in Fig. 2, for placing and two wire-feed motor of protection, need to make wire-feed motor frame 2 according to specific works, can be to be layered up and down, can be with left-right situs, it is also possible to be divided into two single frames or taking other forms to place wire-feed motor even omits；The present embodiment wire-feed motor frame 2 is upper and lower hierarchy, in wire-feed motor frame 2 side, with wire-feed motor current/voltage adjusting knob correspondence position, leaves current/voltage regulation mouth 11, for regulating the current/voltage of this wire-feed motor；Current/voltage regulation mouth 11 is provided with cover plate, and cover plate is connected with wire-feed motor frame 2 by hinge；At wire-feed motor frame 2 end face, observation panel 13 is left in the position corresponding with welding wire wheel, fly out and extraneous foreign body interference welding wire operating because of fortuitous event for placing welding wire for observing welding wire working order, cover plate is also installed at this observation panel 13, is connected with frame by hinge；At wire-feed motor frame 2 trailing flank, the position of welding wire wheel partial below has upper and lower two observation panels 13, observes the operating condition of two wire-feed motor respectively, and the two observation panel 13 is fitted without cover plate；Wire-feed motor frame 2 central dividing plate and base plate are provided with wire-feed motor fixed plate 12, so, two wire-feed motor are arranged on the relevant position of wire-feed motor frame 2, are integrally forming, enhanced stability, also allow for the movement of entirety, wire-feed motor frame 2 simple in construction, convenient, multiple functional, easy to use, improve safety.
As shown in Fig. 3, relay coil the 16, first data wire the 7, second data wire 8, permutator 15 composition control circuit, controlling to connect on loop permutator 15 and the coil of relay coil 16, between source of welding current circuit board 14 and first data wire the 7, second data wire 8, connect relay normally-closed contact 17 and the relay normally open contact 18 of relay coil 16.
As Fig. 4 shows, trachea 9 is drawn by gas cylinder 4, is divided into parallel branch by trachea threeway 10 before entering wire-feed motor, and the electromagnetic valve carried with first wire-feed motor the 31, second wire-feed motor 32 respectively is connected.
The work process of this example:
As shown in Fig. 3, when permutator 15 is on the gear that the first wire-feed motor 31 works, control loop not connect, the relay normally-closed contact 17 of relay coil 16 is in closure state, first wire-feed motor 31 is in running order, and by electric current thereon, voltage knob regulation welding conditions；When on the gear that permutator 15 is placed on the second wire-feed motor 32 work, the permutator 15 controlling loop closes, the coil of relay coil 16 has electricity, its relay normally-closed contact 17 disconnects, relay normally open contact 18 closes, second wire-feed motor 32 is in running order, again by electric current thereon, voltage knob regulation welding conditions；That is the specification of the first wire-feed motor 31 and the second wire-feed motor 32 can be separately controlled, and is independent of each other, and two groups of wire feeders are changed conveniently.
Fig. 4 shows, the break-make of gas circuit is controlled by the data wire of wire-feed motor, when the first wire-feed motor 31 or the second wire-feed motor 32 are in running order, its electromagnetic valve is just for channel status, so gas circuit of its welding gun is open-minded, when it is off, its electromagnetic valve is just for off state, thus the gas circuit of its welding gun disconnects.
On one embodiment of the present of invention has been described in detail, but described content is only presently preferred embodiments of the present invention, it is impossible to be considered the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement etc., within all should still belonging to the patent covering scope of the present invention.
