Description

Technical Field

[0001] The invention relates to the technical field of submerged arc welding, in particular to a semi-automatic submerged arc welding solder recovery device. Background Art

[0002] In modern industrial production, semi-automatic submerged arc welding has been widely used in many fields such as machinery manufacturing, shipbuilding, bridge construction, etc. due to its high efficiency and high-quality welding effects. However, during the submerged arc welding process, a large amount of incompletely melted solder will be generated. If it is not effectively recycled, it will not only cause a huge waste of resources, but also increase production costs.

[0003] At present, most of the common semi-automatic submerged arc welding solder recovery equipment on the market adopt the traditional negative pressure recovery method, that is, negative pressure is generated by a vacuum pump, and the residual solder in the welding area is sucked into the recovery pipe by a suction nozzle, and finally stored in the recovery bin, where the suction nozzle is fixedly installed on the welding machine head. Although this recovery method can achieve solder recovery to a certain extent, it has many obvious disadvantages. On the one hand, the suction nozzle is directly fixed to the welding machine head. When encountering non-planar weldments, the height of the suction nozzle needs to be adjusted frequently to maintain the high efficiency of flux recovery, which is very troublesome. On the other hand, the vacuum pump continuously runs to generate negative pressure to maintain the air flow speed to suck back the solder. This process consumes a lot of electricity, resulting in high overall energy consumption of the equipment. At the same time, the solder recovery is often not smooth due to air flow fluctuations, and even blockage occurs in the recovery pipe, which seriously affects the production progress and the normal operation of the equipment. Therefore, a semi-automatic submerged arc welding solder recovery equipment is proposed to solve the above problems. Summary of the invention

[0011] Through the concentrating box body, the communication channel between the inner space and the outer space of the concentrating box body can be reduced, and the ability to resist external air flow interference can be improved, which is used to increase the recovery effect.

[0012] Through the matching relationship between the spherical hole and the spherical positioning ring, the communication channel between the inner space and the outer space of the concentrating box body can be reduced, the ability to resist external air flow interference can be improved, and the recovery effect can be further increased; the adaptability of the intake duckbill can also be increased, and the applicability is stronger.

[0013] Through the inclined slit, the high-pressure air blows obliquely towards the surface of the welded part, which is used to push the residual flux particles to roll and approach the intake duckbill, playing a role in recycling the kinetic energy of the exhaust gas, with better energy-saving effect and higher recovery effect.

[0014] Pressure is applied to the free end of the force-aggregating box through the bent pressure spring strip to ensure that the walking roller is in close contact with the surface of the weldment and does not lift up.

[0020] The gap between the focusing box and the surface of the weld is blocked by a baffle plate to reduce the connecting channel between the internal space of the focusing box and the external space, thereby improving the ability to resist external airflow interference.

[0021] The scattered flux particles are thrusted by the gathering plate, so that the scattered flux particles are gathered under the gathering box and enter the air flow ejected from the purge hole, so as to increase the recovery effect.

[0022] Air is sprayed obliquely toward the weld surface through the purge hole to push the scattered flux particles into the air field between the inclined slit and the intake duckbill, resulting in a better recovery effect.

[0023] Further, the adaptation mechanism includes an adaptation screw rod, which is rotatably installed on the focusing box body.

[0024] By adopting the above technical solution to control the state of the gathering mechanism, and further controlling the elevation angle of the focusing box body, so that the elevation angle of the focusing box body is adapted to the thickness of the flux embedding, and at the same time used to control the distance between the uptake nozzle and the surface of the welded part.

[0025] Further, the locking mechanism includes a locking block, which is installed on the positioning part. A cylindrical chamber is opened inside the locking block.

[0027] Compared with the prior art, the semi-automatic submerged arc welding solder recovery equipment has the following beneficial effects: First, through the locking mechanism of the present invention, the installation component can be erected, so that the installation component will not swing down when people transfer the submerged arc welding equipment, and it is avoided that the installation component swings down to hinder people from transferring the submerged arc welding equipment. Through the design that the installation component can be flipped, the position of the uptake nozzle can be adaptively adjusted according to the characteristics of the surface of the welded part, without manual operation, which saves time and effort.

The high-pressure air blows obliquely towards the surface of the welded part through the inclined slit, which is used to push the remaining flux particles to roll and approach the intake duckbill, playing a role in recycling the kinetic energy of the exhaust gas, and having a better energy-saving effect. The high-pressure air also enters the inner cavity of the baffle through the ventilation hose and is sprayed obliquely towards the surface of the welded part through the purge holes, which is used to push the scattered flux particles into the gas field between the inclined slit and the intake duckbill, resulting in a better recovery effect and improving the practicability of the semi-automatic submerged arc welding solder recovery equipment.

[0029] Third, in the present invention, the necking mechanism can adjust the opening height of the hole below the necking plate, so that the opening height of the hole below the necking plate is adapted to the weld seam, which is used to reduce the communication channel between the internal space and the external space of the cohesion box body and improve the ability to resist external air flow interference. The slit mechanism can adjust the distance between the bottom edge of the free end face of the cohesion box body and the surface of the welded part, so that the distance between the bottom edge of the free end face of the cohesion box body and the surface of the welded part is small enough, which is used to further reduce the interference of external air flow. Through the cooperation of the gathering mechanism and the adaptation mechanism, the distance between the intake duckbill and the surface of the welded part can be adjusted. Through the gathering mechanism, the communication channel between the internal space and the external space of the cohesion box body is reduced again, and the interference of external air flow is reduced again. The influence of external air flow on the ability of the intake duckbill to pick up flux particles is smaller, which helps to improve the recovery effect and avoid the problem of unsmooth solder recovery caused by air flow fluctuations or even blockage in the recovery pipeline, and has better stability, ensuring the production progress and the normal operation of the equipment.

[0058] Working principle: first, press the load-bearing plate 911 with your finger and apply an upward thrust to it, then the load-bearing plate 911 moves the transmission disc 907 upward, then the transmission disc 907 squeezes the preload spring 906, the preload spring 906 is elastically compressed, and the elastic potential energy increases, then the transmission disc 907 enters the rectangular groove 904 through the semi-cylinder 908 with the plug-in rectangular plate 909, then the plug-in rectangular plate 909 is separated from the locking bevel tooth 912, then the traction spring 308 applies a flipping force to the swing arm 303, and at the same time, gravity also applies a flipping force to the swing arm 303, then the swing arm 303 flips downward with the flip cam 302 as the center axis, and then the swing arm 303 passes through the intake bend 306 with the polymer The force mechanism 4 flips synchronously, and then the walking roller 607 falls on the surface of the weldment. Then the focusing box 401 flips downward with the walking roller 607 as the center axis. At the same time, the intake elbow 306 with the spherical positioning ring 405 flips inside the spherical hole 403 with the directional latch 406 as the center axis. Then the expansion plate 304 contacts the pressure spring bar 407 and applies thrust to it. Then the free end of the pressure spring bar 407 tilts upward, and the elastic potential energy increases. Then the fixed end of the pressure spring bar 407 applies pressure to the free end of the focusing box 401 to ensure that the walking roller 607 is close to the surface of the weldment and does not tilt. Then the shielding plate 702 and the gathering plate 703 fall on the surface of the weldment. The focusing mechanism 4 is in place at this point. Then, rotate the shrinkage screw 602 through the shrinkage round cap 603. After that, under the action of thread fit, the shrinkage screw 602 drives the shrinkage platform 604 to move upward. Then, the shrinkage platform 604 drives the walking roller 607 to move upward relative to the cohesion box body 401 through the shrinkage support rod 605 and the shrinkage strip 606. Next, the bottom edge of the free end face of the cohesion box body 401 gradually approaches the surface of the welded part, and the distance between the bottom edge of the free end face and the surface of the welded part gradually decreases until the distance between the bottom edge of the free end face and the surface of the welded part is small enough to reduce the interference of external air flow, and at the same time ensure that there is no contact between the cohesion box body 401 and the welded part to avoid wear between the cohesion box body 401 and the welded part; Then, apply an upward lifting force to the necking plate 503. Next, the necking plate 503 moves upward until the opening height of the hole below the necking plate 503 is adapted to the weld seam. After that, remove the lifting force. Then, the damping strip fixes the position of the necking plate 503 under the action of friction; Then, rotate the adaption screw 801 through the adaption round cap 802. After that, the adaption small block 803 moves downward under the action of thread fit. Then, the adaption small block 803 drives the L-shaped bending rod 804 to move downward. Next, the L-shaped bending rod 804 pushes the shielding plate 702 to rotate downward relative to the cohesion box body 401 with the gathering axis 701 as the central axis. At the same time, the shielding plate 702 pulls the tension spring 705 through the front short rod 704, and the tension spring 705 is elastically stretched, and the elastic potential energy increases. After that, the connecting end of the cohesion box body 401 is lifted upward. Then, the distance between the bottom edge of the end face of the connecting end of the cohesion box body 401 and the surface of the welded part increases. By the same principle, if the adaption round cap 802 is rotated in the reverse direction, the distance between the bottom edge of the end face of the connecting end of the cohesion box body 401 and the surface of the welded part will decrease, so as to adjust the distance between the bottom edge of the end face of the connecting end of the cohesion box body 401 and the surface of the welded part, and further adjust the distance value between the intake duckbill 307 and the surface of the welded part until the distance value matches the thickness of the flux embedding; Then, the intake fan 201 is turned on, and the intake fan 201 drives the air flow. Then, the air carrying the flux particles passes through the intake duckbill 307, the intake elbow 306, and the intake hose 204 in turn into the flux box 102. Then, the flux particles fall inside the flux box 102 and are separated from the air. Then, the air passes through the filter bag box 203, and the filter bag box 203 removes dust from the air. Then, the air passes through the transfer hard pipe 202, the intake fan 201, the steering hard pipe 205, the return hose 206, and the transfer pipe 412 into the air pressure chamber 411. Then, part of the air passes through the inclined slit 410. Blowing toward the surface of the weldment is used to push the residual flux particles to roll and approach the intake duckbill 307, so as to recycle the kinetic energy of the exhaust gas, and achieve better energy saving effect. Then, the fast-flowing airflow between the inclined slit 410 and the intake duckbill 307 forms an air field, which is used to increase the ability of the intake duckbill 307 to absorb flux particles, and achieve better recovery effect. Then, the remaining air enters the inner cavity of the shielding plate 702 through the ventilation hose 707 and is tiltedly sprayed toward the surface of the weldment through the purge hole 708, so as to push the scattered flux particles into the air field between the inclined slit 410 and the intake duckbill 307, and achieve better recovery effect. Then the submerged arc welding device 1 is pushed forward, and then the gathering plate 703 moves forward, and then the gathering plate 703 applies thrust to the scattered flux particles, and then the scattered flux particles gather under the focusing box 401 and enter the airflow ejected from the purge hole 708, and then the scattered flux particles are sucked away by the intake duckbill 307, so as to achieve the purpose of recycling; When the surface of the weldment changes, the surface of the weldment applies thrust to the focusing mechanism 4 through the gathering mechanism 7 and the adapting mechanism 8, causing the focusing mechanism 4 to flip accordingly. At the same time, the swing arm 303 also flips accordingly to ensure that the shielding plate 702 and the gathering plate 703 fall on the surface of the weldment, thereby realizing adaptive adjustment of the duckbill 307.
