Technical Field

[0001] This utility model relates to the field of roll forming welding technology, specifically a roll forming welding machine for the long side of radiator fins. Background Technology

[0002] Finned radiators utilize fins to increase the heat dissipation area, thereby improving heat dissipation efficiency. Their core principle lies in increasing the radiator's surface area to reduce thermal resistance and effectively improve heat transfer efficiency. Compared to traditional radiators, finned radiators have stronger heat dissipation capabilities, quickly dissipating heat in a short time; therefore, the production of fins is crucial.

[0003] Under current technology, steel is often cut into appropriate lengths before being extruded. This process is cumbersome, cannot be carried out continuously, has low production efficiency, cannot be mass-produced, and the extruded products have low precision, which affects the heat dissipation effect of the radiator.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figures 1-4 As shown, this utility model provides a technical solution for a long-side roll forming welding machine for radiator fins. The machine comprises a mounting base 1, a transmission wheel assembly 2, a hydraulic press 3, and a welding body 4. The mounting base 1 is connected to the hydraulic press 3 via a transmission wheel assembly 2, and the hydraulic press 3 is connected to the welding body 4 via another transmission wheel assembly 2. Two support seats 5 are symmetrically mounted on the mounting base 1. Each support seat 5 has a first through hole 6 and a second through hole 7. The two first through holes 6 are connected by a forming roller 8, and the two second through holes 7 are connected by a flattening roller 9. A first drive motor 12 is symmetrically mounted on the mounting base 1. Two first pulleys 16 are mounted on the output shaft of the first drive motor 12. A second pulley 17 is mounted on both the forming roller 8 and the flattening roller 9. One first pulley 16 is connected to the second pulley 17 on the forming roller 8 via a belt 18, and the other first pulley 16 is connected to the second pulley 17 on the flattening roller 9 via a belt 18.

[0025] A transition arc plate 21 is installed on the support base 5. The transition arc plate 21 is located between the forming roller 8 and the flattening roller 9. The side of the transition arc plate 21 closest to the flattening roller 9 is arc-shaped. When the long side of the fin needs to be produced, the first drive motor 12 is started. Through the transmission of the first pulley 16, the second pulley 17 and the belt 18, the flattening roller 9 and the forming roller 8 are driven to rotate. When the steel passes through the flattening roller 9, it is flattened, which facilitates subsequent rolling and forming. At the same time, the rotation of the flattening roller 9 also drives the steel to be conveyed forward. After passing through the flattening roller 9, the steel is transferred from below the transition arc plate 21 to the forming roller 8. The setting of the transition arc plate 21 prevents the steel from warping upwards and affecting the forming. In a simple and feasible way, the steel is rolled into the required shape by the rolling of the flattening roller 9 and the forming roller 8. The length of the processed product is not limited, continuous production is possible, the surface quality of the product is good, the dimensional accuracy is high, the production efficiency is high, and mass production is possible.

[0026] The first through hole 6 is oblong. The upper surface of the first through hole 6 is connected to the forming roller 8 via a spring 20. The spring 20 is rotatably mounted on the forming roller 8 and is in a compressed state. The support base 5 has two sliding grooves 10, which are symmetrical about the first through hole 6. A push plate 11 is slidably mounted on the sliding grooves 10. The first drive motor 12 is equipped with a first drive gear 13 and a driven gear 14, which mesh with each other. A tension ring 19 is mounted on the driven gear 14. The tension ring 19 is an open ring. A push rod 15 is installed on the 4, and the push rod 15 is located in the middle of the opening of the tension ring 19. The first drive motor 12 drives the driven gear 14 to rotate through the first drive gear 13. The push rod 15 rotates synchronously with the driven gear 14. When the push rod 15 contacts the push plate 11, it pushes the push plate 11 to drive the forming roller 8 to slide upward along the slide groove 10. The spring 20 continues to be compressed. When the forming roller 8 moves upward, there will be no more downward forming pressure on the plate. When the driven gear 14 rotates through a certain angle, the push rod 15 disengages from the push plate 11, and the spring 20 gives the forming roller 8 downward pressure. The forming roller 8 continues to roll and form the steel.

[0027] During normal roll forming by the forming roller 8, the belt 18 used for transmission between the forming roller 8 and the first drive motor 12 is squeezed and bent by the tension ring 19. When the forming roller 8 moves upward, the notch of the tension ring 19 faces the belt 18, reducing the deformation of the belt 18 and facilitating the upward movement of the forming roller 8. This ensures that the belt 18 will not deform and prevents it from affecting the transmission between the first drive motor 12 and the forming roller 8. The setting of the push rod 15 and the tension ring 19 allows for roll forming as needed without affecting the transmission of the forming roller 8, thus ensuring product quality and production efficiency.

[0028] The welding body 4 includes two bases 401, each of which has a working cavity 402 and a mounting groove 403. A rotating ring 406 is rotatably mounted on the mounting groove 403. The two rotating rings 406 are connected to a first module slide rail 409 via three connecting rods 407. A slider 410 is slidably mounted on the first module slide rail 409. A second module slide rail 411 is mounted on the slider 410. An electric telescopic rod 412 is mounted on the second module slide rail 411. A push column 413 is mounted on the electric telescopic rod 412. A second drive motor 404 is installed in the working cavity 402. A transmission gear 405 is mounted on the output shaft of the second drive motor 404. The transmission gear 405 meshes with the rotating ring 406.

[0029] The three connecting rods 407 are arranged circumferentially with the first module slide rail 409. The two connecting rods 407 that are far apart are symmetrically equipped with receiving wheel sets 408. The receiving wheel sets 408 are three rows of parallel rollers. A sensor 416 is installed on the side of the receiving wheel sets 408 away from the hydraulic press 3. The sensor 416 is electrically connected to the second drive motor 404 and the electric telescopic rod 412. The electric telescopic rod 412 is electrically connected to the first module slide rail 409. The first module slide rail 409 is electrically connected to the second module slide rail 411.

[0030] A mounting bracket 414 is installed on the side of the base 401 away from the hydraulic press 3. Two welding torches 415 are slidably mounted on the mounting bracket 414. After being processed by the hydraulic press 3, the roll-formed steel is cut into the long fin-shaped sides of a radiator. Welding is required between two of the long fin-shaped sides, such as... Figure 6 As shown, when the first wing-shaped long side is conveyed to one wheel gap of the receiving wheel assembly 408, and the wing-shaped long side contacts the sensor 416, the sensor 416 sends an electrical signal to start the second drive motor 404. The second drive motor 404 drives the rotating ring 406 to rotate 180 degrees through the transmission gear 405. At the same time, the first wing-shaped long side also rotates 180 degrees under the support of the receiving wheel assembly 408. After the rotation is completed, the second wing-shaped long side is conveyed into the other wheel gap of the receiving wheel assembly 408. When the second wing-shaped long side contacts the sensor 416, the sensor 416 sends an electrical signal to control the electric telescopic rod 412 to extend until the push column 413 is at the same height as the two wing-shaped long sides. The electric telescopic rod 412 sends an electrical signal to control the slider 410 to move along the first module slide rail 409. At the same time, the push column 413 pushes the two wing-shaped long sides forward to the welding position and then returns to the initial position.

[0031] A mounting bracket 414 is installed on the side of the base 401 away from the hydraulic press 3. A positioning sensor 417 is installed on the welding position on the side of the mounting bracket 414 away from the rotating ring 406. Two welding torches 415 are slidably mounted on the mounting bracket 414. The positioning sensor 417 is electrically connected to the welding torch 415. When the long sides of the two wing-shaped blades move forward until both long sides of the wing-shaped blades contact the positioning sensor 417, the positioning sensor 417 sends a signal to control the welding torch 415 to start welding at the contact point of the two long sides of the wing-shaped blades. Using the welding body 4, the forged and sheared wing blades are flipped, combined, and then welded, which greatly reduces the labor intensity of workers and improves production efficiency.

[0032] The working principle of this utility model:

[0033] When the long side of the fin needs to be produced, the first drive motor 12 is started. Through the transmission of the first pulley 16, the second pulley 17 and the belt 18, the flattening roller 9 and the forming roller 8 are driven to rotate. When the steel passes through the flattening roller 9, it is flattened, which facilitates subsequent rolling and forming. At the same time, the rotation of the flattening roller 9 also drives the steel to be conveyed forward. After passing through the flattening roller 9, the steel is transferred from below the transition arc plate 21 to the forming roller 8. The transition arc plate 21 is set to prevent the steel from warping upwards and affecting the forming. In a simple and feasible way, the steel is rolled into the required shape by the flattening roller 9 and the forming roller 8. The length of the processed product is not limited, and continuous production is possible. The surface quality of the product is good, the dimensional accuracy is high, the production efficiency is high, and mass production is possible.

[0034] The first drive motor 12 drives the driven gear 14 to rotate via the first drive gear 13. The push rod 15 rotates synchronously with the driven gear 14. When the push rod 15 contacts the push plate 11, it pushes the push plate 11 to drive the forming roller 8 to slide upward along the slide groove 10. The spring 20 continues to be compressed. When the forming roller 8 moves upward, there will be no more downward forming pressure on the plate. When the driven gear 14 rotates through a certain angle, the push rod 15 disengages from the push plate 11, and the spring 20 gives the forming roller 8 downward pressure. The forming roller 8 continues to roll and form the steel.

[0035] During normal roll forming by the forming roller 8, the belt 18 used for transmission between the forming roller 8 and the first drive motor 12 is squeezed and bent by the tension ring 19. When the forming roller 8 moves upward, the notch of the tension ring 19 faces the belt 18, reducing the deformation of the belt 18 and facilitating the upward movement of the forming roller 8. This ensures that the belt 18 will not deform and prevents it from affecting the transmission between the first drive motor 12 and the forming roller 8. The setting of the push rod 15 and the tension ring 19 allows for roll forming as needed without affecting the transmission of the forming roller 8, thus ensuring product quality and production efficiency.

[0036] After being processed by hydraulic press 3, the roll-formed steel is cut into fin-shaped long sides for radiators. Two fin-shaped long sides need to be welded together, such as... Figure 6As shown, when the first wing-shaped long side is conveyed to one wheel gap of the receiving wheel set 408, and the wing-shaped long side contacts the sensor 416, the sensor 416 sends an electrical signal to start the second drive motor 404. The second drive motor 404 drives the rotating ring 406 to rotate 180 degrees through the transmission gear 405. At the same time, the first wing-shaped long side also rotates 180 degrees under the support of the receiving wheel set 408. After the rotation is completed, the second wing-shaped long side is conveyed into another wheel gap of the receiving wheel set 408. When the second wing-shaped long side contacts the sensor 416, the sensor 416 sends an electrical signal to control the electric telescopic rod 412 to extend until the push column 413 is at the same height as the two wing-shaped long sides. The electric telescopic rod 412 sends an electrical signal to control the slider 410 to move along the first module slide rail 409. At the same time, the push column 413 pushes the two wing-shaped long sides forward to the welding position and then returns to the initial position.

[0037] A mounting bracket 414 is installed on the side of the base 401 away from the hydraulic press 3. A positioning sensor 417 is installed on the welding position on the side of the mounting bracket 414 away from the rotating ring 406. Two welding torches 415 are slidably mounted on the mounting bracket 414. The positioning sensor 417 is electrically connected to the welding torch 415. When the long sides of the two wing-shaped blades move forward until both long sides of the wing-shaped blades contact the positioning sensor 417, the positioning sensor 417 sends a signal to control the welding torch 415 to start welding at the contact point of the two long sides of the wing-shaped blades. By using the welding body 4, the forged and sheared wing blades are flipped and combined, and then welded. This can greatly reduce the labor intensity of workers and improve production efficiency.
