Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a cold-rolled thin plate production welding device and method. Background Art

[0002] The plate radiator is a heat exchange device used on oil-immersed transformers. The plate radiator is mainly welded by multiple heat dissipation units, oil collecting pipes and reinforcing ribs. The heat dissipation unit is welded by two identical cold-rolled thin steel plates to form an oil flow path. Two confluence ports for oil inlet and outlet are formed at both ends of the oil flow path. The oil collecting pipe is located at both ends of the plate radiator to form oil inlet and outlet pipelines connected to the transformer. Multiple heat dissipation units are arranged at equal intervals along the axial direction of the oil collecting pipe and are connected to the oil collecting pipe. Reinforcing ribs are connected between multiple heat dissipation units to improve the overall structural strength and prevent deformation.

[0003] The existing patent (Announcement No.: CN116871798A) discloses a plate-type radiator welding device, including a base, a bracket, a top pressure assembly, a welding assembly and a rib discharge assembly. The bracket is arranged on the base, and a plurality of slots are provided on the upper surface of the bracket; two top pressure assemblies are arranged on both sides of the bracket opposite to each other, and the top pressure assembly has a first telescopic end, and the first telescopic end is connected to a limiting plate; the welding assembly includes a support beam, two welding mechanisms, and a second driving mechanism, the support beam is arranged above the bracket, and the rib discharge assembly is arranged on the support beam. The present invention can weld and fix multiple heat dissipation units at equal intervals on the oil collecting pipe through the joint action of the base, the bracket, the top pressure assembly, the welding assembly and the rib discharge assembly, and can weld the ribs on the heat dissipation units. Compared with manual welding, it is easier to ensure that multiple heat dissipation units are arranged at equal intervals, which helps to reduce the labor intensity of workers and improve welding efficiency. In the process of implementing the above invention, the inventors found the following problems: when the device is welding reinforcing ribs, the rib discharge assembly arranges the ribs on the surface of the heat dissipation unit, and then the welding assembly performs welding. Since the ribs are not fixed by other components, the ribs may move during welding, resulting in poor welding effect. At the same time, the device can only perform single-sided rib welding, and when welding the other side, the heat dissipation unit needs to be flipped 180 degrees, which is inconvenient.

[0014] A method for using a cold-rolled sheet production welding device comprises the following steps:

[0015] S1. Welding: Start the two mechanical arms and move them down along the slide rail 4. When the mechanical arms move down, they will move the welding gun to weld the connection points between the reinforcing ribs and the heat dissipation unit. When the mechanical arms move to the bottom, the rack 2 will mesh with the gear 1 and drive the gear 1 to rotate. The two gears 1 will rotate synchronously through the connecting rod. The gear 1 will drive the reciprocating screw to rotate through the elastic pawl and the ratchet. The reciprocating screw will drive the connecting block threadedly connected to it to move. The connecting block drives the sliding bracket connected to it to move outward. Since the relative clamping block 1 will compress the spring 1 when it is subjected to force and move away from each other, the clamping bracket can move outward with the sliding bracket;

[0016] After the mechanical arm moves to the bottom, the reinforcement ribs are also welded, and the mechanical arm moves upward to reset. At the same time, the drive motor is started, and the drive motor drives the two linear screws to rotate. The linear screw drives the sliders threaded therewith to slide along the slide rails 1 and 2 for a certain distance, and stops after the gear 1 and the adjacent rack 1 are fully engaged. The gear 1 rotates under the drive of the rack 1, and drives the connected reciprocating screw to rotate. The reciprocating screw drives the connecting block to move inward and reset, and the clamping bracket also moves inward and resets with the connecting block;

[0017] During the reciprocating movement of the connecting block, the plate 2 also moves accordingly, so that the guide rod 2 is slidably connected with the guide groove 1. Under the guidance of the guide groove 1, the sliding rod and the rack 3 reciprocate and translate. When the rack 3 moves, it meshes with the gear 2, driving the gear 2 to reciprocate and rotate 90 degrees. Due to the setting of the end face ratchet 1 and the end face ratchet 2, the storage bracket will rotate 90 degrees under the drive of the gear 2 and will not reset. During the reciprocating movement of the connecting block, since the guide rod 1 is slidably connected in the parallelogram slide groove, the clamping bracket can grab the reinforcement ribs on the rotated storage bracket and abut the reinforcement ribs against the heat dissipation unit. At this time, the mechanical arm is started to move down for welding, and reinforcement ribs are added to the storage bracket.

[0018] Repeat the above steps until all the reinforcement ribs on one side of the heat dissipation unit are welded;

[0019] S2, unloading: start hydraulic rod 1 to drive the welding mechanisms on both sides to move outward, and start the drive motor at the same time to make the slider move back and reset, and make the mechanical arm move up and reset. After the welding mechanisms are separated, start hydraulic rod 2 to drive the fixing mechanism to move down. Since the crank guide rod is slidably connected in the guide groove 2, the fixing mechanism will first flip to a horizontal state, and then continue to move down until the heat dissipation unit abuts against the bottom surface of the placement groove and stops;

[0020] Start the hydraulic rod three to move the arc-shaped clips on both sides outwards, loosen the fixation of the heat dissipation unit, and then remove the locking block. After turning over the plate three, the welded heat dissipation unit and the reinforcement ribs on the placement rack can be removed;

[0021] S3, loading: place the heat dissipation unit on the placement rack, start hydraulic rod three, move the arc-shaped clamp inward to fix the heat dissipation unit, and then start hydraulic rod two to drive the fixing mechanism to move upward. When it reaches the top, the fixing mechanism will flip to a vertical state. At this time, start hydraulic rod one to drive the welding mechanisms on both sides to reset inward, and welding can be carried out again.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, by means of two symmetrically arranged welding mechanisms, the reinforcing ribs can be welded on the two sides of the heat dissipation unit at one time without turning over the heat dissipation unit, thus saving the welding time of the reinforcing ribs and greatly increasing the welding efficiency.

[0024] 2. In the present invention, by setting up a material storage mechanism and a material moving mechanism, during the welding process of the welding mechanism, the material moving mechanism can remove the reinforcing ribs from the material storage mechanism and firmly fix the reinforcing ribs on the heat dissipation unit, so that the reinforcing ribs will not move during the welding process, thereby ensuring the welding effect.

[0025] 3. In the present invention, by setting up the hydraulic rod 2 and the flipping mechanism, the fixing mechanism can be switched between the horizontal and vertical states. When the fixing mechanism is vertical, it is convenient for the welding mechanism to weld the reinforcing ribs on both sides of the heat dissipation unit at the same time. When the fixing mechanism is horizontal, it is convenient to place a single heat dissipation unit and take out the heat dissipation unit as a whole with welded reinforcing ribs.

[0042] In this embodiment, the material storage mechanism 6 includes a material storage bracket 601, and the two material storage brackets 601 are symmetrically connected to the connecting bracket 4 for rotation. Two symmetrical clamping blocks 602 are slidably connected to the four branches of the material storage bracket 601. A spring 603 is connected between the clamping block 602 and the material storage bracket 601, and four supporting brackets 604 are evenly fixedly connected to the material storage bracket 601.

[0043] In this embodiment, the supporting bracket 1 505 and the supporting bracket 2 604 are used to support the reinforcing rib 13 to prevent the reinforcing rib 13 from falling off the material moving mechanism 5 or the material storing mechanism 6 due to insufficient clamping force of the clamping block 1 503 or the clamping block 2 602 .

[0045] In this embodiment, the initial elastic force of spring 2 603 is greater than the initial elastic force of spring 1 504, so that when the clamping block 1 503 abuts against the reinforcing rib 13 on the storage mechanism 6, due to the smaller initial elastic force of spring 1 504, the two opposite clamping blocks 1 503 will be squeezed apart by the reinforcing rib 13 first, and then the clamping bracket 502 will push the reinforcing rib 13 to squeeze apart the two opposite clamping blocks 2 602, thereby removing the reinforcing rib 13 from the storage mechanism 6.

[0049] A method for using a cold-rolled sheet production welding device comprises the following steps:

[0050] S1. Welding: Start the two mechanical arms 206 and move the mechanical arms 206 downward along the slide rail 205. When the mechanical arms 206 move downward, the welding gun 207 will be moved to weld the connection points between the reinforcing rib 13 and the heat dissipation unit 10. When the mechanical arms 206 move to the bottom, the rack 2 517 will mesh with the gear 1 511 and drive the gear 1 511 to rotate. The two gears 1 511 will rotate synchronously through the connecting rod 512. The gear 1 511 will drive the reciprocating screw 509 to rotate through the elastic pawl 513 and the ratchet 514. The reciprocating screw 509 will drive the connecting block 510 threadedly connected thereto to move. The connecting block 510 drives the sliding bracket 501 connected thereto to move outward. Since the relative clamping block 1 503 will compress the spring 1 504 and move away from each other when subjected to force, the clamping bracket 502 can move outward with the sliding bracket 501.

[0051] After the mechanical arm 206 moves to the bottom, the reinforcement rib 13 is also welded, and the mechanical arm 206 moves upward to reset, and the drive motor 210 is started at the same time. The drive motor 210 drives the two linear screws 208 to rotate, and the linear screws 208 drive the slider 204 threadedly connected thereto to slide along the slide rail 1 and the slide rail 201 for a certain distance, and stop after the gear 1 511 and the adjacent rack 1 516 are fully engaged. The gear 1 511 rotates driven by the rack 1 516 and drives the connected reciprocating screw 509 to rotate. The reciprocating screw 509 drives the connecting block 510 to move inward and reset, and the clamping bracket 502 also moves inward and resets with the connecting block 510;

[0052] During the reciprocating movement of the connecting block 510, the flat plate 2 615 also moves accordingly, so that the guide rod 2 614 is slidably connected with the guide groove 1 616. Under the guidance of the guide groove 1 616, the sliding rod 612 and the rack 3 613 reciprocate and translate. When the rack 3 613 moves, it meshes with the gear 2 610, driving the gear 2 610 to reciprocate and rotate 90 degrees. Due to the settings of the end face ratchet 1 605 and the end face ratchet 2 608, the storage bracket 601 will rotate 90 degrees driven by the gear 2 610 and will not reset. During the reciprocating movement of the connecting block 510, since the guide rod 1 506 is slidably connected in the parallelogram slide groove 508, the clamping bracket 502 can grab the reinforcing rib 13 on the rotating storage bracket 601 and abut the reinforcing rib 13 against the heat dissipation unit 10. At this time, the mechanical arm 206 is started to move downward for welding, and the reinforcing rib 13 is added to the storage bracket 601.

[0053] Repeat the above steps until all the reinforcing ribs 13 on one side of the heat dissipation unit are welded;

[0054] S2, unloading: start the hydraulic rod 1 3 to drive the welding mechanisms 2 on both sides to move outward, and start the drive motor 210 at the same time to make the slider 204 move back and reset, and make the mechanical arm 206 move up and reset.

8. A method for using a cold-rolled sheet production welding device, using the cold-rolled sheet production welding device as claimed in any one of claims 1 to 7, characterized in that: The steps include: S1. Welding: Start the two mechanical arms (206) and move the mechanical arms (206) downward along the slide rail 4 (205). When the mechanical arms (206) move downward, the welding gun (207) will be moved to weld the connection point between the reinforcing rib (13) and the heat dissipation unit (10). When the mechanical arms (206) move to the bottom, the rack 2 (517) will mesh with the gear 1 (511) and drive the gear 1 (511) to rotate. The two gears 1 (511) rotate synchronously through the connecting rod (512). The wheel 1 (511) will drive the reciprocating screw (509) to rotate through the elastic pawl (513) and the ratchet wheel (514), and the reciprocating screw (509) will drive the connecting block (510) threadedly connected thereto to move, and the connecting block (510) will drive the sliding bracket (501) connected thereto to move outward. When the relative clamping block 1 (503) is subjected to force, the spring 1 (504) will be compressed and move away from each other, so that the clamping bracket (502) can move outward along with the sliding bracket (501); After the mechanical arm (206) moves to the bottom, the reinforcing rib (13) is also welded, and the mechanical arm (206) moves upward to reset, and the drive motor (210) is started at the same time. The drive motor (210) drives the two linear screws (208) to rotate, and the linear screws (208) drive the slider (204) threadedly connected thereto to slide along the slide rails 1 (1) and 2 (201) for a certain distance, and stop after the gear 1 (511) and the adjacent rack 1 (516) are fully engaged. The gear 1 (511) rotates under the drive of the rack 1 (516), and drives the connected reciprocating screw (509) to rotate, and the reciprocating screw (509) drives the connecting block (510) to move inward and reset, and the clamping bracket (502) also moves inward and resets with the connecting block (510); During the reciprocating movement of the connecting block (510), the second plate (615) also moves accordingly, so that the second guide rod (614) is slidably connected with the first guide groove (616). Under the guidance of the first guide groove (616), the sliding rod (612) and the third rack (613) reciprocate and translate. When the third rack (613) moves, it meshes with the second gear (610), driving the second gear (610) to reciprocate and rotate 90 degrees. Due to the arrangement of the first end ratchet (605) and the second end ratchet (608), the storage bracket (601) will rotate on the gear. The second wheel (610) rotates 90 degrees and will not reset. During the reciprocating movement of the connecting block (510), since the guide rod (506) is slidably connected in the parallelogram slide groove (508), the clamping bracket (502) can grab the reinforcing rib (13) on the rotating material storage bracket (601) and abut the reinforcing rib (13) against the heat dissipation unit (10). At this time, the mechanical arm (206) is started to move downward for welding, and the reinforcing rib (13) is added to the material storage bracket (601); Repeat the above steps until all the reinforcing ribs (13) on one side of the heat dissipation unit are welded; S2, unloading: start the hydraulic rod 1 (3) to drive the welding mechanisms (2) on both sides to move outward, and start the driving motor (210) at the same time to make the slider (204) move back and reset, and make the mechanical arm (206) move up and reset. After the welding mechanisms (2) are separated, start the hydraulic rod 2 (7) to drive the fixing mechanism (9) to move downward. Since the crank guide rod (1105) is slidably connected in the guide groove 2 (1104), the fixing mechanism (9) will first flip into a horizontal state, and then continue to move downward until the heat dissipation unit (10) stops when it abuts against the bottom surface of the placement groove (1201); Start the hydraulic rod three (904) to move the arc-shaped clips on both sides outward, loosen the fixation of the heat dissipation unit (10), and then remove the locking block (1103). After turning over the flat plate three (1102), the welded heat dissipation unit (10) and the reinforcing ribs (13) on the placement frame (12) can be removed; S3, loading: Place the heat dissipation unit (10) on the placement rack (12), start the hydraulic rod three (904), move the arc-shaped clamp inward to fix the heat dissipation unit (10), and then start the hydraulic rod two (7) to drive the fixing mechanism (9) to move upward. When reaching the top, the fixing mechanism (9) will flip to a vertical state. At this time, start the hydraulic rod one (3) to drive the welding mechanisms (2) on both sides to reset inward, and welding can be carried out again.
