It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1 to 3, the embodiment of the invention provides a narrow gap submerged arc welding device, which belongs to the field of welding equipment and is used for welding a welding position in a narrow gap. By using the narrow gap submerged arc welding device, the welding wire can smoothly reach the corner in the narrow gap by rotating the guide piece 220 in the narrow gap, so that the problem that the welding wire cannot reach the corner in the narrow gap due to the blocking of the side wall of the narrow gap is solved.
In some preferred embodiments, the narrow gap submerged arc welding apparatus includes a frame 100 and a wire guide assembly 200, the wire guide assembly 200 including a traction member 210, a guide member 220, and a guide driver 230, the traction member 210 being configured to draw welding wire for movement, the guide member 220 being rotatably mounted to the frame 100, the guide member 220 having a lead-in end for receiving welding wire drawn by the traction member 210, and a lead-out end for guiding welding wire, the guide driver 230 being configured to drive the guide member 220 to rotate relative to the frame 100 to adjust the position of the lead-out end.
In the above embodiment, the wire is pulled toward the guide 220 by the pulling member 210, and the guide 220 is extended into the narrow gap together with the wire. The guiding member 220 is driven to rotate relative to the frame 100 by the guiding driving member 230, so that the welding wire led out from the leading-out end can reach the corners of the narrow gap, and then the welding flux is buried in the welding wire to weld the corners in the narrow gap. By using the narrow gap submerged arc welding device provided by the invention, the welding wire can smoothly reach the corners through rotating the guide piece 220 extending into the narrow gap instead of the whole translation welding device, so that the problem that the welding wire cannot reach the corners in the narrow gap due to the blocking of the side wall of the narrow gap is solved.
In some preferred embodiments, the guide driving member 230 includes a guide driving portion 231 and a torsion bar 232, the torsion bar 232 is rotatably mounted on the frame 100, the guide driving portion 231 is in transmission connection with one end of the torsion bar 232, the other end of the torsion bar 232 has a toggle pin 2321, and the toggle pin 2321 toggles the guide member 220 to rotate relative to the frame 100.
It can be appreciated that the narrow gap submerged arc welding apparatus provided by the present invention is suitable for welding operation in a narrow gap, and the guide driving portion 231 is usually a component such as a motor, a cylinder or an electric push rod, on one hand, such a component is usually large in size and is inconvenient to extend into the narrow gap, and on the other hand, such a component is difficult to withstand high temperature and cannot adapt to high temperature environment in the narrow gap. Therefore, the guide driving part 231 is positioned outside the narrow gap, drives the torsion bar 232 to rotate, and further drives the guide piece 220 to rotate, thereby playing a role in remotely controlling the guide piece 220.
As long as the implementation of the toggle pin 2321 for toggling the guide member 220 is possible, in the above embodiments, in some specific embodiments, the guide member 220 is provided with a slot 221, and the toggle pin 2321 is embedded in the slot 221. It should be emphasized that the inner wall of the slot 221 is not completely attached to the poking pin 2321, and the poking pin 2321 can shake within the slot 221 by a certain extent, so as to avoid the poking pin 2321 from being blocked in the process of driving the guide member 220 to rotate.
In some preferred embodiments, the narrow gap submerged arc welding apparatus further comprises a flux assembly 300, the flux assembly 300 comprising a lead-out member 310 and a storage tank 320 for buffering flux, one end of the lead-out member 310 being connected to the storage tank 320, the other end thereof being erected on the lead-out end side, the lead-out member 310 being adapted to lead out flux in the storage tank 320.

The air flow led out by the air guide pipe 410 can purge impurities at the position to be welded, so that the impurities are prevented from affecting subsequent welding.
It will be appreciated that the distance between the air duct 410 and the outlet end needs to be strictly controlled, and the distance between the air duct 410 and the outlet end is too far, so that the air flow may purge impurities to the to-be-welded position. If the distance between the two is too small, the air flow may possibly go to a position where it is covered with flux later.
To facilitate adjusting the distance between the air guide duct 410 and the guiding end, in some preferred embodiments, the air guide duct 410 is slidably disposed on the rack 100 along a horizontal direction, and the air guide duct 410 may stay at any position on the sliding track thereof.

In this embodiment, a horizontal waist-shaped slot 110 is formed on the frame 100, and the air guide pipe 410 is mounted on the waist-shaped slot 110 by bolts. By loosening the bolts, the air duct 410 can be pulled to slide along the kidney-shaped groove 110, and by tightening the bolts, the relative position between the air duct 410 and the frame 100 can be fixed.
It should be noted that, the air supply member (not shown in the drawing) is configured to supply air into the air guide pipe 410, so that an air flow for blowing impurities is formed in the air guide pipe 410, and embodiments of the air supply member (not shown in the drawing) satisfying the requirement are all feasible, and may be an air compressor or an air pump.

In some preferred embodiments, the guide 220 is provided with a guide hole 222 through which the welding wire passes, and the guide hole 222 is formed with a guide cone at one end near the traction member 210. So that the welding wire guided out of the traction member 210 can be more smoothly guided into the guide member 220.
As long as the implementation of the traction element 210 that can draw the welding wire to travel is possible, in some preferred embodiments, the traction element 210 includes a traction driving portion 211 and a plurality of traction wheels 212 that are staggered, the plurality of traction wheels 212 are rotatably mounted on the frame 100, and the traction driving portion 211 drives at least part of the traction wheels 212 to rotate; wherein the wire sequentially encircles a plurality of traction wheels 212.
The welding wire sequentially surrounds the traction wheels 212, and the traction driving part 211 guides the driving part 231 to rotate with the traction wheels 212, so that each traction wheel 212 drives the welding wire to be guided to the guide piece 220. The guide 220 is provided with a guide hole 222 through which the welding wire passes, and one end of the guide hole 222 near the traction member 210 is formed with a guide cone. So that the welding wire guided out of the traction member 210 can be more smoothly guided into the guide member 220. The guide 220 is then extended into the narrow gap with the welding wire. The guiding member 220 is driven to rotate relative to the frame 100 by the guiding driving member 230, so that the welding wire led out from the leading-out end can reach the corners of the narrow gap, and then the welding flux is buried in the welding wire to weld the corners in the narrow gap. By using the narrow gap submerged arc welding device provided by the invention, the welding wire can smoothly reach the corners through rotating the guide piece 220 extending into the narrow gap instead of the whole translation welding device, so that the problem that the welding wire cannot reach the corners in the narrow gap due to the blocking of the side wall of the narrow gap is solved.
