Still be provided with main recovery tube 10 on the arm body 1, with main recovery tube 10 communicates with each other and is connected and be provided with first recovery branch pipe 11 and second recovery branch pipe 12, the bottom of first recovery branch pipe 11 the bottom of second recovery branch pipe 12 the bottom of first solder flux pipe 6 and the bottom of second solder flux pipe is on same straight line at the ascending projection of vertical side, gun tube 5 is located the bottom of first recovery branch pipe 11 with between the bottom of second recovery branch pipe 12, be provided with third control valve 13 on the first recovery branch pipe 11, be provided with fourth control valve 14 on the second recovery branch pipe 12.
And a feeding groove 15 is formed in the top of the welding flux box 2. One side of the welding agent box 2, which is far away from the arm body 1, protrudes out of the welding agent box 2, a buffering part 16 is arranged on the buffering part 16, the bottom end of the buffering part 16 is inclined, the top end of the buffering part 16 is vertical, the bottom end of the buffering part 16 faces the arm body 1, and the feeding groove 15 is located in the middle of the top end of the buffering part 16.
The utility model provides a pair of longmen submerged arc welding machine's welding arm unit when processing the work piece, first solder flux pipe 6 is located the low reaches of welding gun pipe 5, opens first control valve 7 this moment, closes second control valve 8, then the solder flux in the solder box 2 falls down the work piece through first solder flux pipe 6 and needs the welded seam in, the arm body 1 is along with the portal frame activity, and welding gun pipe 5 is located the upper reaches of first solder flux pipe 6 to can carry out normal welding. After welding at one position in the length direction of the workpiece is finished, the first control valve 7 is closed, wire feeding and welding are stopped, the position of the workpiece is adjusted, the second position to be welded on the workpiece is moved to be right below a straight line (namely the movement direction of the portal frame and the arm body 1) where the bottom end of the first welding flux tube 6, the bottom end of the welding gun tube 5 and the bottom end of the second welding flux tube are located, the second control valve 8 is opened, welding flux falls into a seam to be welded at the second position through the second welding flux tube, and then the arm body 1 moves towards the opposite direction through the portal frame to weld simultaneously (wherein the welding flux can be guided into the whole length of the seam to be welded of the workpiece no matter the first welding flux tube 6 and the second welding flux tube). Because the gantry frame can weld the workpiece in the back-and-forth process, the gantry frame and the arm body 1 can be prevented from idle running, useless energy consumption is reduced, and the energy-saving performance is good.
Wherein the first recovery branch pipe 11 and the first flux tube 6 are located on the same side of the gun tube 5, and the second recovery branch pipe 12 and the second flux tube are located on the same side of the gun tube 5. The main recycling pipe 10 is externally connected with an air suction device for forming negative pressure in the main recycling pipe 10, and meanwhile, the main recycling pipe 10, the first recycling branch pipe 11 and the second recycling branch pipe 12 are made of high temperature resistant materials, such as high temperature resistant rubber or stainless steel pipes, and the third control valve 13 and the fourth control valve 14 are also high temperature resistant valves which can bear the temperature of the welding flux. When the first flux pipe 6 discharges flux for welding, the third control valve 13 is closed, the fourth control valve 14 is opened, the main recovery pipe 10 and the second recovery branch pipe 12 form a passage, and the second recovery branch pipe 12 sucks excess flux for recovery and utilization; when the second flux pipe discharges flux, the fourth control valve 14 is closed, the third control valve 13 is opened, the main recovery pipe 10 and the first recovery branch pipe 11 form a passage, and the first recovery branch pipe 11 sucks away the excess flux for recovery.
The blanking parts 6b at the bottom ends of the first and second flux tubes 6 and 6 are both vertically downward, so that the flux can be better ensured to fall into the seam to be welded. Meanwhile, because the widths of the seams on different workpieces are different, the widths of the welding flux required to fall are different (the openings of the blanking parts 6b which are too large can emit too much welding flux, and the recovery effect is poor), and different blanking parts 9 can be connected to the bottom ends of the blanking parts 6b at the moment. Wherein the connecting portion 9a of the blanking member 9 can be screwed to the blanking portion 6b, so that the dismounting and connection between the blanking member 9 and the blanking portion 6b are relatively simple. After the blanking part 9 is connected to the blanking part 6b, the size of the opening of actual blanking is the cross-sectional area of the blanking part 9b, so that the blanking parts 9b with different diameters can be selected according to the size of an actual seam, and the welding flux can fall into the seam with high quality (not only can be ensured to fill the seam, but also is not discharged too much welding flux). The blanking member 9 may be a straight cylindrical member for lowering the blanking height of the blanking portion 6b to prevent the flux from flying.
When the flux is poured into the flux box 2, the flux is poured through the vessel 17 (the vessel 17 can also be in a rectangular shape according to the situation, and the feeding groove 15 is also rectangular at the moment) as shown in the figure, firstly, the flux is positioned in the vessel 17 and is contained with the flux, when the flux is poured into the flux box 2, the vessel 17 is clamped into the feeding groove 15, and the inner wall of the feeding groove 15 is attached to the outer periphery of the vessel 17, so that the position stability of the vessel 17 can be ensured, and meanwhile, the flux can be prevented from sliding out from the side part of the flux box 2. Meanwhile, when the welding flux falls from the vessel 17, the welding flux firstly falls into the inclined part at the bottom of the buffering part 16, the inclined part can play a role in buffering, the welding flux is prevented from directly impacting the bottom of the welding flux box 2, and meanwhile, the buffering part 16 also increases the total containing amount of the welding flux.
The actual structural structures of other structures on the wall body, such as the wire reel 3, the wire feeding wheel 4, the welding gun tube 5 and other structures not mentioned, and the working principle of these structures are conventional structures, and are not limited and described herein, and should be understood as the common general knowledge in the art. Meanwhile, the arm body 1 can horizontally slide on the portal frame, so that the gantry type moving robot is suitable for workpieces at different positions. The sliding structure can be a sliding structure in a gantry type H-shaped steel submerged arc welding machine as disclosed in a patent with the publication number of CN 202861602U, namely, two welding arms are connected to a transverse sliding frame, and the positions of the welding arms in the horizontal direction can be changed by moving the welding arms along the transverse sliding frame; or the middle part of the portal frame is provided with a horizontal groove, the two sides of the arm body 1 are movably attached to the groove, then a screw rod is horizontally arranged in the groove, the two arm bodies 1 are in threaded connection with the screw rod, the directions of the threads on the two arm bodies 1 are opposite, and the directions of the threads on the two sides of the screw rod are also opposite, so that the arm body 1 can be supported and driven by the screw rod to move, and the two arm bodies 1 can be close to or far away from the screw rod.
It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
