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, and bridge construction due to its high efficiency and high-quality welding results. 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, a vacuum pump is used to generate negative pressure, and a suction nozzle is used to suck the residual solder in the welding area into the recovery pipe, and finally stored in the recovery silo. The suction nozzle is fixedly installed on the welding 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 head. When encountering non-planar welds, the suction nozzle height needs to be frequently adjusted to maintain 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 airflow 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 airflow fluctuations, and even blockages occur in the recovery pipe, seriously affecting 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 force-gathering box, the communication channel between the internal space of the force-gathering box and the external space can be reduced, and the ability to resist external airflow 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 connecting channel between the internal space and the external space of the focusing box can be reduced, the ability to resist external airflow interference can be improved, and the recovery effect can be further increased; it can also increase the adaptability of the intake duckbill and make it more applicable.

[0013] The high-pressure air is blown obliquely toward the surface of the weldment through the inclined slit, which is used to push the residual flux particles to roll and approach the intake duckbill, thereby recycling the kinetic energy of the exhaust gas, achieving better energy-saving and higher recovery effects.

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

[0021] The gathering plate applies thrust to the scattered flux particles, so that the scattered flux particles gather 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 weldment 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 better recovery effect.

[0024] By adopting the above technical solution, the state of the gathering mechanism is controlled, and then the elevation angle of the focusing box is controlled so that the elevation angle of the focusing box is adapted to the thickness of the flux embedment, and at the same time it is used to control the distance between the intake duckbill and the weldment surface.

[0025] Furthermore, the locking mechanism includes a locking block, which is installed on the positioning part, and a cylindrical cavity is provided inside the locking block, and a guide slot and a rectangular groove are provided on the surface of the locking block, the guide slot is connected to the cylindrical cavity, and a semi-cylindrical hole is provided on the inner wall of the rectangular groove, and the semi-cylindrical hole is connected to the cylindrical cavity, and a pre-compression spring is provided inside the cylindrical cavity, and a transmission disc is connected to the pre-compression spring, and the transmission disc is slidably inserted in the cylindrical cavity, and a semi-cylinder is connected to the transmission disc, and the semi-cylindrical hole is slidably inserted in the semi-cylindrical hole, and a plug-in rectangular plate is connected to the semi-cylinder, and the plug-in rectangular plate is slidably inserted in the rectangular groove, and a chamfered inclined surface is provided on the plug-in rectangular plate, and a bearing plate is connected to the transmission disc, and the bearing plate is slidably inserted in the guide slot, and the locking mechanism also includes locking inclined surface teeth, which are connected to the extension plate and adapted to the chamfered inclined surface.

[0026] By adopting the above technical solution, the installation component can be erected so that the installation component will not swing down when people transfer the submerged arc welding equipment, thereby preventing the installation component from swinging down and hindering people from transferring the submerged arc welding equipment.

[0027] Compared with the existing technology, this semi-automatic submerged arc welding solder recovery equipment has the following beneficial effects:

[0028] 1. The present invention can set up the installation component through the locking mechanism, so that the installation component will not swing down when people transfer the submerged arc welding equipment, thereby avoiding the installation component swinging down and hindering people from transferring the submerged arc welding equipment. The flippable design of the installation component can make the position of the intake duckbill adaptively adjusted according to the characteristics of the weld surface, without the need for manual operation, saving time and effort. The movable connection between the installation component and the focusing mechanism makes the intake duckbill more adaptable, thereby making the semi-automatic submerged arc welding solder recovery equipment applicable to the horizontal and inclined surfaces of the weldment, thereby improving the practicality of the semi-automatic submerged arc welding solder recovery equipment.

[0029] 2. The present invention passes high-speed exhaust gas into the air pressure chamber through the intake device, so that high pressure is formed inside the air pressure chamber. The high-pressure air is blown obliquely toward the surface of the weldment through the inclined slit, which is used to push the residual flux particles to roll and approach the intake duckbill, thereby recycling the kinetic energy of the exhaust gas and achieving better energy-saving effects. The high-pressure air also enters the inner cavity of the baffle through the ventilation hose and is sprayed obliquely toward the surface of the weldment through the purge hole, which is used to push the scattered flux particles into the air field between the inclined slit and the intake duckbill, thereby achieving better recovery effects and improving the practicality of the semi-automatic submerged arc welding solder recovery equipment.

[0030] 3. The present invention can adjust the opening height of the hole below the shrinking plate through the shrinking mechanism, so that the opening height of the hole below the shrinking plate is adapted to the weld, which is used to reduce the communication channel between the internal space of the focusing box and the external space, and improve the ability to resist external airflow interference. The shrinking mechanism can adjust the distance between the bottom edge of the free end face of the focusing box and the surface of the weld, so that the distance between the bottom edge of the free end face of the focusing box and the surface of the weld is small enough to further reduce the interference of external airflow. The cooperation of the gathering mechanism and the adapting mechanism can adjust the distance between the intake duckbill and the surface of the weld. The gathering mechanism can further reduce the communication channel between the internal space of the focusing box and the external space, and further reduce the interference of external airflow. The external airflow has less influence on the ability of the intake duckbill to absorb flux particles, which helps to improve the recycling effect, avoid the problem of poor solder recovery due to airflow fluctuations, and even blockage in the recovery pipeline. The stability is better, ensuring the normal operation of production progress and equipment.

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 pin 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. At this point, the force focusing mechanism 4 is in place.

[0078] Then, the contraction screw 602 is rotated through the contraction round cap 603, and then the contraction screw 602 moves upward with the contraction platform 604 under the action of the threaded fit, and then the contraction platform 604 moves upward relative to the focusing box 401 with the walking roller 607 through the contraction support rod 605 and the contraction strip 606, and then the bottom edge of the free end face of the focusing box 401 gradually approaches the surface of the weld, and the distance between the bottom edge of the free end face and the surface of the weld gradually decreases until the distance between the bottom edge of the free end face and the surface of the weld is small enough to reduce external airflow interference and ensure that there is no contact between the focusing box 401 and the weld, thereby avoiding wear between the focusing box 401 and the weld;

[0079] Then, an upward lifting force is applied to the shrinking plate 503, and the shrinking plate 503 moves upward until the opening height of the hole below the shrinking plate 503 matches the weld seam. Then, the lifting force is removed, and the damping strip fixes the position of the shrinking plate 503 under the action of friction force.

[0080] Then, the adapting screw 801 is rotated by the adapting round cap 802, and then the adapting block 803 moves downward under the action of the threaded fit, and then the adapting block 803 moves downward with the L-shaped bending rod 804, and then the L-shaped bending rod 804 pushes the shielding plate 702 to flip downward relative to the focusing box 401 with the focusing 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, and then the focusing The connection end of the force box body 401 is lifted upward, and then the distance between the bottom edge of the connection end face of the force box body 401 and the surface of the weldment increases. Based on the same principle, if the adaptor round cap 802 is rotated in the opposite direction, the distance between the bottom edge of the connection end face of the force box body 401 and the surface of the weldment will be reduced, thereby adjusting the distance between the bottom edge of the connection end face of the force box body 401 and the surface of the weldment, and then adjusting the distance value between the intake duckbill 307 and the surface of the weldment until the distance value matches the thickness of the flux embedment;

[0081] 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. After that, 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 and purifies 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. After that, part of the air is inclined through the inclined slit 410. The air is blown toward the surface of the weldment to push the remaining flux particles to roll and approach the intake duckbill 307, thereby recycling the kinetic energy of the exhaust gas and achieving better energy-saving effects. Then, the rapidly 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, thereby achieving better recovery effects. Then, the remaining air enters the inner cavity of the baffle 702 through the ventilation hose 707 and is sprayed obliquely toward the surface of the weldment through the purge hole 708, thereby pushing the scattered flux particles into the air field between the inclined slit 410 and the intake duckbill 307, thereby achieving better recovery effects.

[0082] Then the submerged arc welding equipment 1 is pushed forward, and then the gathering plate 703 moves forward. After that, the gathering plate 703 applies a thrust to the scattered flux particles, and then the scattered flux particles gather under the focusing box 401 and enter the air flow ejected from the purge hole 708. Then the scattered flux particles are sucked away by the intake duckbill 307 to achieve the purpose of recycling;

[0083] When the surface of the weldment changes, the surface of the weldment applies a 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 the adaptive adjustment of the duckbill 307.

[0084] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
