Description

Technical Field

[0001] The present invention belongs to the technical field of fin processing, and specifically relates to a metal fin forming device for an air-cooled heat exchange device and a processing method thereof. Background Art

[0002] An air-cooled heat exchange device, also known as an air cooler or an air-cooled heat exchanger, is a heat exchange device that uses ambient air as a cooling medium. By means of a fan, air is forced to flow across the outside of finned tubes, so that the high-temperature process fluid inside the tubes can be cooled or condensed. Air-cooled heat exchange devices are widely used in various heat dissipation occasions in industrial production. Their performance directly affects the operating efficiency and energy consumption of the devices. As the core component of an air-cooled heat exchange device, the forming quality and efficiency of metal fins have an important impact on the overall performance of the device.

[0003] The authorized publication number "CN119500900A" discloses "a fin forming device and a forming method, which relate to the technical field of fin processing. The technical solution is as follows: a forming table, the tabletop of which can rotate; a forming module, which is used as a lower die when a fin is formed by stamping; a punching and cutting assembly, which is fixedly arranged directly above the forming station of the forming table; the punching and cutting assembly can simultaneously punch and cut the material on the forming module. The beneficial effect of the present invention is that when the stamping module cooperates with the forming module to stamp a metal strip, the metal strip is cut by the cutting module. Therefore, it effectively solves the problem that after the stamping equipment stamps the metal strip released by the uncoiler, the strip-shaped fins still need to be continuously conveyed to a cutting device for cutting, and the fins cannot be cut while being stamped and formed, resulting in the need to rely on a cutting device to complete the fin forming process and unable to directly form the fins through the stamping equipment. Furthermore, the technical effect of stamping and forming the metal strip and automatically cutting it is achieved."

[0004] The above patent achieves the technical effect of stamping and forming a metal strip and automatically cutting it. However, it is not easy to clean the lower die of the above patent. After long-term use of the lower die, metal chips or dust will accumulate inside the lower die. These impurities cause wear to the die during the stamping process and result in pits on the surface of the formed metal fins, thereby affecting the appearance and quality of the metal fins. In addition, the rotation of the forming table to replace the positions of the two lower dies requires a large circular or arc-shaped space, increasing the overall floor area of the equipment. Summary of the Invention

[0005] The object of the present invention is as follows: Through the installation mechanism, the alternating movement of two installation platforms is realized, the replacement of two lower molds is carried out, which is convenient for the continuous processing of metal fins, improves work efficiency. Such a double-station alternating design makes the equipment more compact in the horizontal direction, can reduce the overall floor area of the equipment, and avoids the large circular or arc-shaped space required for the rotation and alternation of two stations. Through the flipping mechanism, the lower mold can be automatically flipped, which can realize the rapid blanking of metal fins. Cooperating with the cleaning mechanism, it can remove metal chips and impurities on the surface of the lower mold, reduce the wear of the lower mold, extend the service life of the lower mold, and avoid the accumulation of impurities in the lower mold, which affects the appearance and quality of metal fins.

Such a dual-station alternating design makes the equipment more compact in the horizontal direction, can reduce the overall floor area of the equipment, and avoids the large circular or arc-shaped space required for the rotation and alternation of the two stations.

[0027] (2) In the present invention, through the flipping mechanism, the lower mold can be automatically flipped, enabling the rapid blanking of metal fins. In cooperation with the cleaning mechanism, the metal chips and impurities on the surface of the lower mold can be removed, reducing the wear of the lower mold, extending the service life of the lower mold, and preventing impurities from accumulating in the lower mold and affecting the appearance and quality of the metal fins.

The linkage assembly is arranged on the rotating shaft 205, and the exchange assembly is arranged on the mounting frame 1.

[0046] In this embodiment: Through the cooperation of the exchange assembly and the linkage assembly, the gear 206 drives the rotating shaft 205 to rotate on the mounting frame 1, driving the rack 204 to drive the moving table 203 to move on the mounting frame 1, so that one of the mounting tables 201 moves below the upper mold 401, and the other mounting table 201 moves away from the upper mold 401, realizing the alternating entry and exit of the two mounting tables 201, improving work efficiency. Such a double-station alternating design makes the equipment more compact in the horizontal direction, can reduce the overall floor area of the equipment, and avoids the large-area circular or arc-shaped space required for the rotation and alternation of the two stations.

The air pipe 501 is installed on the top of the outer wall of the lifting frame 506.

[0060] In this embodiment: The second hydraulic cylinder 504 drives the limit frame 505 to move horizontally on the mounting frame 1.

The internal circuit principle structure belongs to the common knowledge of those skilled in the art and will not be introduced in detail here. Its model can be selected according to the actual use situation.

[0061] In use, step one: stamping forming: the first hydraulic cylinder 404 drives the fixed plate 405 to move downward, so that the upper die 401 cooperates with the lower die 402 to stamp the metal strip on the lower die 402. After the forming is completed, the upper die 401 rises back to the initial position. Step two: station alternation: the first forward and reverse motor 207 drives the rotating shaft 208 to rotate, so that the push rod 209 rotates. The push hole 210 on the push rod 209 pushes the movable shaft 213 to move in the U-shaped hole 211. The movable shaft 213 drives the movable rod 212 to move along the U-shaped track. At the same time, the movable rod 212 slides in the limit frame 214, so that the mounting table 201 on the movable rod 212 moves, making the lower die 402 that has completed stamping forming move away from the upper die 401. As the rotating shaft 208 rotates, it can drive one of the transmission wheels 215 to rotate. Cooperating with the transmission belt 216, the other transmission wheel 215 drives the rotating shaft 205 to rotate on the mounting frame 1, driving the gear 206 to rotate. The rack 204 drives the moving table 203 to move on the mounting frame 1, making the mounting table 201 on the moving table 203 move below the upper die 401, realizing the rapid alternating movement of the two mounting tables 201 and replacing the two lower dies 402. Step three: blanking: the second forward and reverse motor 305 drives the threaded rod 304 to rotate, realizing the movement of the moving rod 303. The connecting rod 306 drives the stamping table 301 to rotate on the rotating frame 302, realizing the flipping of the lower die 402, so that the formed metal fins fall to the designated position. Step four: cleaning: the second hydraulic cylinder 504 drives the limit frame 505 to move horizontally on the mounting frame 1. Under the action of the wave hole 503 and the connecting shaft 507, when the lifting frame 506 moves horizontally with the limit frame 505, it can drive the lifting frame 506 to move up and down according to the serrated cavity of the lower die 402. The high-pressure air nozzle 502 on the lifting frame 506 sprays the high-pressure gas in the air pipe 501 onto the surface of the lower die 402 at a certain speed and angle, removing the metal chips and impurities inside the lower die 402. After the cleaning of the lower die 402 is completed, the lower die 402 returns to its original position for the next round of station alternation.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
