Description

Technical Field

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

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

[0003] The existing patent (publication number: CN116871798A) discloses a finned radiator welding device, including a base, a bracket, a pressing assembly, a welding assembly, and a rib discharging assembly. The bracket is arranged on the base, and a plurality of card slots are formed on the upper surface of the bracket; two pressing assemblies are relatively arranged on both sides of the bracket, and the pressing assembly has a first telescopic end, and a limiting plate is connected to the first telescopic end; 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 discharging assembly is arranged on the support beam. Through the combined action of the base, the bracket, the pressing assembly, the welding assembly, and the rib discharging assembly, the present invention can weld and fix multiple heat dissipation units on the oil collecting pipe at equal intervals and can weld the rib bars 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 the welding efficiency. The inventor found the following problems during the implementation of the above invention: When welding the reinforcing rib bars, the rib discharging assembly arranges the rib bars on the surface of the heat dissipation unit, and then the welding assembly performs the welding. Since the rib bars are not fixed by other components, the rib bars may move during welding, resulting in poor welding effects. At the same time, this device can only perform single-sided rib bar welding. When welding the other side, the heat dissipation unit needs to be flipped 180 degrees, which is rather inconvenient.

[0013] Preferably, the placement rack is evenly provided with a plurality of equally spaced placement slots for placing the heat dissipation units, and the placement rack is also evenly provided with a plurality of equally spaced accommodation slots for accommodating reinforcing ribs.

[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. Blanking: Start Hydraulic Rod 1 to drive the welding mechanisms on both sides to move outwards. At the same time, start the drive motor to make the slider move back to its original position and make the robotic arm move up to its original position. After the welding mechanisms separate, start Hydraulic Rod 2 to drive the fixing mechanism to move downwards. Since the crank-slider is slidably connected to Guide Slot 2, the fixing mechanism will first flip to a horizontal state and then continue to move downwards until the heat dissipation unit abuts against the bottom surface of the placement groove and stops.

[0020] Start Hydraulic Rod 3 to move the arc-shaped clamping pieces on both sides outwards to release the fixation of the heat dissipation unit. Then remove the locking block. After flipping Plate 3, the welded heat dissipation unit and the reinforcing rib on the placement rack can be removed.

[0021] S3. Loading: Place the heat dissipation unit on the placement rack. Start Hydraulic Rod 3 to move the arc-shaped clamping pieces inwards to fix the heat dissipation unit. Then start Hydraulic Rod 2 to drive the fixing mechanism to move upwards. When it reaches the top, the fixing mechanism will flip back to a vertical state. At this time, start Hydraulic Rod 1 to drive the welding mechanisms on both sides to move inwards and reset, and welding can be carried out again.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. In the present invention, through the two symmetrically arranged welding mechanisms, the reinforcing ribs can be welded on both sides of the heat dissipation unit simultaneously at one time, without flipping the heat dissipation unit, saving the welding time of the reinforcing ribs and greatly increasing the welding efficiency.

[0024] 2. In the present invention, through the provided stockpiling mechanism and material transfer mechanism, during the welding process of the welding mechanism, the material transfer mechanism can remove the reinforcing rib from the stockpiling mechanism and firmly fix the reinforcing rib on the heat dissipation unit, so that the reinforcing rib will not move during the welding process, ensuring the welding effect.

[0025] 3. In the present invention, through the provided Hydraulic Rod 2 and flipping mechanism, the fixing mechanism can be switched between a horizontal state and a vertical state. 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 entire heat dissipation unit welded with the reinforcing rib.

[0039] In this embodiment, the material transfer mechanism 5 includes a sliding bracket 501 which is slidably connected to the connecting bracket 4. Four clamping brackets 502 are slidably connected to the sliding bracket 501. Two clamping blocks 503 are symmetrically and slidably connected to one end of each clamping bracket 502. A first spring 504 is connected between the clamping block 503 and the clamping bracket 502. A reinforcing rib 13 is clamped between the two clamping blocks 503. A first supporting bracket 505 is fixedly connected to the lowermost clamping bracket 502. The reinforcing rib 13 abuts against the first supporting bracket 505, and the reinforcing rib 13 also abuts against the heat dissipation unit 10.

[0040] In this embodiment, a first guide rod 506 is fixedly connected to the other end of the clamping bracket 502. Four first plates 507 corresponding to the positions of the clamping brackets 502 are fixedly connected to the connecting bracket 4. A parallelogram chute 508 is formed in the first plate 507. The first guide rod 506 is slidably connected in the parallelogram chute 508 at the corresponding position. Two reciprocating lead screws 509 are symmetrically and rotatably connected to both ends of the connecting bracket 4.

[0041] In this embodiment, the elastic pawl 513 and the ratchet 514 are arranged such that only one-way transmission is possible between the first gear 511 and the reciprocating lead screw 509. After the welding is completed, during the reset process of the slider 204, the rotation of the first gear 511 when it is engaged with the first rack 516 will not drive the rotation of the reciprocating lead screw 509. Similarly, the upward movement of the robotic arm 206 will not drive the rotation of the reciprocating lead screw 509 either.

[0042] In this embodiment, the stock storage mechanism 6 includes a stock storage support 601. Two of the stock storage supports 601 are symmetrically and rotatably connected to the connection support 4. Two symmetric clamping blocks II 602 are slidably connected to each of the four branches of the stock storage support 601. A spring II 603 is connected between the clamping block II 602 and the stock storage support 601. Four support brackets II 604 are uniformly and fixedly connected to the stock storage support 601.

[0043] In this embodiment, the support bracket I 505 and the support bracket II 604 are used to support the reinforcing rib 13 to prevent the reinforcing rib 13 from falling off the material transfer mechanism 5 or the stock storage mechanism 6 due to insufficient clamping force of the clamping block I 503 or the clamping block II 602.

[0044] In this embodiment, a face ratchet I 605 is fixedly connected to the stock storage support 601. Two fixed brackets I 606 are symmetrically and fixedly connected to the connection support 4. A rotating rod 607 is rotatably connected to each of the fixed brackets I 606. A face ratchet II 608 is slidably connected to each of the rotating rods 607. A spring III 609 is connected between the face ratchet II 608 and the fixed bracket I 606. The adjacent face ratchet I 605 and face ratchet II 608 are engaged.

A guide rod II 614 is fixedly connected to the other end of the sliding rod 612. The rack III 613 meshes with the adjacent gear II 610 during movement. A flat plate II 615 is fixedly connected to the connection block 510. A guide groove I 616 is formed in the flat plate II 615. During the movement of the flat plate II 615, the guide groove I 616 will slidably connect with the adjacent guide rod II 614.

[0045] In this embodiment, the initial elastic force of the spring II 603 is greater than the initial elastic force of the spring I 504. When the clamping block I 503 abuts against the reinforcing rib 13 on the stock storage mechanism 6, since the initial elastic force of the spring I 504 is small, the two opposite clamping blocks I 503 will be first pushed apart by the reinforcing rib 13, and then the clamping bracket 502 will push the reinforcing rib 13 to push apart the two opposite clamping blocks II 602, thereby removing the reinforcing rib 13 from the stock storage mechanism 6.

[0046] In this embodiment, the fixing mechanism 9 includes a fixing frame 901, and the fixing frame 901 is rotatably connected to the connecting seat 8. Two arc-shaped clamps 902 are symmetrically slidably connected to the fixing frame 901. A number of protrusions 903 are evenly arranged on the arc-shaped clamps 902. The protrusions 903 on both sides are slidably plugged into the heat dissipation unit 10. Four hydraulic rods 3 904 are symmetrically fixedly connected in pairs on the fixing frame 901. The arc-shaped clamps 902 are fixedly connected to the movable ends of the hydraulic rods 3 904 on the same side.

[0047] In this embodiment, the flip mechanism 11 includes a base 1101, and two bases 1101 are symmetrically arranged at both ends of the fixed frame 901. The base 1101 is rotatably connected with a plate three 1102. The base 1101 and the plate three 1102 are symmetrically slidably connected with two locking blocks 1103. The plate three 1102 is provided with a guide groove two 1104. The fixed frame 901 is symmetrically fixedly connected with two crank guide rods 1105, and the crank guide rod 1105 is slidably connected in the guide groove two 1104 on the same side.

[0048] In this embodiment, the placement rack 12 is evenly provided with a plurality of equally spaced placement slots 1201 for placing the heat dissipation units 10 , and the placement rack 12 is also evenly provided with a plurality of equally spaced accommodation slots 1202 for accommodating the reinforcing ribs 13 .

[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. 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;

[0055] Start the hydraulic rod 3 904 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.

Loading: Place the heat dissipation unit 10 on the placement rack 12, start the third hydraulic rod 904 to move the arc-shaped clamping pieces inward to fix the heat dissipation unit 10, and then start the second hydraulic rod 7 to drive the fixing mechanism 9 to move upward. When it reaches the top, the fixing mechanism 9 will turn into a vertical state. At this time, start the first hydraulic rod 3 to drive the welding mechanisms 2 on both sides to reset inward, and welding can be carried out again.

6. A method for using a cold-rolled sheet production welding device, using the cold-rolled sheet production welding device as claimed in claim 4, 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, they move the welding gun (207) 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) meshes with the gear 1 (511) and drives 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 rail 1 (1) and the slide rail 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 along 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 at the same time start the driving motor (210) to move the slider (204) back and reset, and move the mechanical arm (206) upward 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 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 it reaches 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.
