The weld 20 is installed in the body 10 and moves along the body 10. The welding unit 20 receives the welding wire 300 from the wire supply unit 30, injects the welding wire 300 into the flux accumulated on the surface of the site to be welded, and uses the welding wire 300 as an electrode wire to weld the welding wire 300. An arc is generated between 300 and the base metal, and the base metal is welded by the heat. At this time, the generated arc heat melts the welding wire 300, the base material and the flux, the molten flux forms slag, and the molten metal forms the weld bead.

The welding unit 20 may be configured by one electrode, two electrodes, or three electrodes according to the number of electrodes, and the electrode configuration may include a direct current + alternating current or alternating current + alternating current method in the case of two electrodes, and a direct current + alternating current in the case of three electrodes. It can be configured in a + alternating or alternating + alternating + alternating manner.

The welding part 20 generally guides the welding wire 300 to a part to be welded, and may include a welding nozzle 210 for applying a current to the welding wire 300. However, in the present invention, the configuration of the welding portion 20 is not limited thereto, and any configuration may be adopted as long as the configuration of the welding portion used in the conventional submerged welding apparatus is used.

The wire supply unit 30 stably supplies the welding wire 300 to the welding unit 200 during welding. The wire supply unit 30 includes a wire reel 310 in which the welding wire 300 is wound, a wire reel support 320 for supporting the wire reel 310 so that the wire reel 310 is rotatably installed, and a welding wire 300. ), A plurality of guide rollers 341 for changing the direction of the welding wire 300 so that the wire supply motor 330 and the welding wire 300 to be transferred to the welding part 200 may be inserted perpendicularly to the welding nozzle 210. Guide roller portion 340 including a). The wire reel 310 may include a wire escape guard 360 connecting both left and right sides of the wire reel 310 in order to prevent detachment of the wound welding wire 300.

In the empty space in the center of the wire reel 310, a control panel 350 equipped with various instrument panels and control devices is provided. However, the control panel 350 and the wire escape guard 360 may be omitted.

The flux spreader 40 sprays the flux contained therein in front of the weld 20 to the portion to be welded in order to prevent an open arc. Flux spreading unit 40 is a flux storage tank 400 for storing the flux to be sprayed, a hopper 410 used when supplying the flux to the flux storage tank 400, a flux sprayer for dropping the flux to the welding site 420 and a flux supply pipe 430 for transferring the flux from the flux storage tank 400 to the flux spreader 420.

The flux sprayer 420 may be separated from the welder 20 and positioned in front of the welder 20, but as illustrated in FIG. 1, the flux sprayer 420 may be installed at the end of the welding nozzle 210. .

The flux recovery unit 50 is a suction unit 500 for recovering the sprayed flux, a recovery pipe 510 for transferring the flux to the suction unit, and the inside of the suction unit 500 to form a vacuum so that the flux is sucked into the unit ( 500 includes a drive unit 520 driven to be sucked into the inside.

The suction unit 500 includes a body 501, a sealing member 502, and an opening and closing member 503.

The body 501 is still a basic skeleton of the suction unit 500, and is mounted on the flux spreader 40. At this time, the body 501 is empty inside, the bottom is open.

The sealing member 502 is mounted inside the body 501 which is empty inside. The sealing member 502 is open at both the top and bottom. The flux is supplied to the flux spreader 40 through the inside of the sealing member 502.

When the sealing member 502 is mounted to the body 501, it is attached using a spot welding method. This is for the operator to mount the sealing member 502 to the body 501 more easily. However, the method of mounting the sealing member 502 to the body 501 is not limited to spot welding, but may be mounted in various ways such as screw coupling.

The opening and closing member 503 is disposed under the sealing member 502 to serve to seal or open the lower portion of the sealing member 502. The opening and closing member 503 includes an opening and closing plate 504, a rotating rod 505, a rotating handle 506, and an elastic spring 507. The opening and closing plate 504 is a body of the opening and closing member 503 and is disposed below the sealing member 502 to surround the lower portion of the sealing member 502. As the rotary bar 505 is integrally mounted to the lower part of the opening and closing plate 504 and rotates, the opening and closing plate 504 also rotates as the rotating bar 505 rotates. The rotary knob 506 is connected to one side of the rotary rod 505 outside the body 501 and used by the operator to arbitrarily rotate the rotary rod 505. In addition, the rotary knob 506 is restored to its original state by the elastic spring 507 connected to the rotary knob 506. One side of the elastic spring 507 is fixed to the body 501, the other side is connected to the rotary knob 506.

In summary, when the operator rotates the rotary bar 505 in one direction using the rotary knob 506, the opening and closing plate 504 integrally connected with the rotary bar 505 is also rotated. As the opening and closing plate 504 is rotated, the lower part of the sealing member 502 is opened, and the flux inside the sealing member 502 is discharged to the flux spreader 40. Thereafter, the rotary knob 506 is automatically rotated in the reverse direction by the restoring force of the elastic spring 507 so that the opening and closing plate 504 again blocks the lower portion of the sealing member 502.

In addition, the lower part of the sealing member 502 is inclined diagonally inward at a predetermined angle. This is to more smoothly and flexibly discharge when the opening / closing member 503 is opened and the flux is discharged from the sealing member 502 to the flux spreader 40. At this time, the area of the opening and closing member 503 should be longer than the width of the open portion of the sealing member 502. This is because when the area of the open portion of the sealing member 502 and the area of the opening / closing member 503 are the same or short, when the inside of the sealing member 502 is vacuumed by the drive unit 520, the opening / closing member ( This is because air can flow between the 503 and the sealing member 502. Accordingly, the area of the opening / closing member 503 is increased compared to the width of the open portion of the sealing member 502, thereby preventing air from flowing between the opening and closing member 503 and the sealing member 502 when creating a vacuum state. . However, the lower portion of the sealing member 502 may not be inclined at a predetermined angle so that the width of the upper portion and the width of the lower portion may be the same.

The recovery pipe 510 is connected to the suction unit 500 and serves to guide the flux sprayed on the welded portion into the suction unit 500.

The driving unit 520 is disposed above the suction unit 500 to supply suction force into the suction unit 500 to serve to make the inside of the suction unit 500 into a vacuum state. Accordingly, the flux sprayed on the welded portion along the recovery pipe 510 connected to the inside of the suction unit 500 is guided and recovered in the suction unit 500.

The drive unit 520 includes a case 521 and an electric motor (not shown) disposed inside the case.

The power supply unit 60 serves to supply power to the welding unit 20 or the wire supply unit 30, respectively. The power supplied from the power supply unit 60 is 110V. The flux recovery unit 50 is directly connected to the welding unit 20 or unplugged to the control panel 350 of the wire supply unit 30 to receive 110V.

In the conventional welding apparatus, the vacuum and the suction force were maintained by supplying 220 V of power to the flux recovery unit 50. However, in the welding apparatus 1 according to an exemplary embodiment, the opening and closing member 503 and the sealing member 502 may be separated. Even if the 110V power is supplied by the structure, the vacuum and suction force can be maintained in the same manner as in the prior art, and accordingly, there is an advantage of not having to separately provide the power supply unit 60 for the flux recovery unit 50.

In addition, the flux recovery unit 50 may be directly connected to the power supply unit 60.

In addition, when the welding unit 20 receives power from the power supply unit 60, 40 to 80V is supplied by converting DC using a conversion inverter at 110V. When the flux recovery unit 50 is directly connected to the welding unit 20, 110V power is supplied as it is without passing through the inverter.

Components of other embodiments according to the present invention are similar to those of the components of the embodiments described with reference to FIGS. 1 to 5, and thus, detailed descriptions thereof will be omitted.

In another embodiment, as shown, the connection member 70 further includes. The connection member 70 serves to smoothly work by adjusting the height of the flux inlet 511 to the welded portion when the user works. Accordingly, the connection member 70 is formed with a plurality of height adjustment groove 700 in the longitudinal direction. An adjustment protrusion 512 is formed at the flux inlet 511 to be inserted into and fixed to the height adjustment groove 700. At this time, each height adjustment groove 700 is formed to have a different height of the recessed groove. Thus, the operator can adjust the height arbitrarily even during work.

In addition, the bottom surface of the flux inlet 511 is inclined at a predetermined angle with respect to the longitudinal direction and the vertical direction of the flux inlet 511 in order to contact the welded portion more smoothly.

The predetermined angle is about 25 to 80 degrees. If it is less than 25 ㅀ, the flux inlet 511 cannot be brought into proper contact with the welded area, and if it is over 80 ㅀ, the flux inlet 511 cannot be brought into contact with each other at right angles. The problem does not occur.

The user may recover the flux distributed in the welded portion more smoothly by the flux recovery unit 50 according to the height adjusting groove 700 and the flux inlet 511 inclined at a predetermined angle.

The cover 80 is provided with a suction hole 810 for supplying the suction force of the driving unit 520 to the suction unit 500. At this time, the suction hole 810 is connected to the suction pipe 820 protruding into the suction unit 500. The length of the suction pipe 820 is 40 to 60 mm. When less than 40 mm, the flux may be introduced into the driving unit 520 by the suction force, and when more than 60 mm, the suction force may not be properly transmitted to the suction unit 500. However, the suction pipe 820 may be omitted.

The protective cover 800 is connected to the first member 801 and the first member 801 which protrude in the longitudinal direction on one side of the cover 80, that is, the upper inner surface, and in the direction of the suction hole 810. And a second member 802 that is inclined at a predetermined angle to prevent the flux from suctioning the suction hole 810. An elastic body 803 is attached to one side of the first member 801. The reason why the elastic body 803 is attached is to prevent breakage of the flux recovered by the suction unit 500 by directly hitting the first member 801.

However, the shape of the protective cover 800 is not limited to the shape as shown in another embodiment may be formed in various shapes such as round shape.
