[0002] Fins are usually used as heat exchange structures and are placed on the surface of heat exchange devices that need to transfer heat. By placing metal sheets with strong thermal conductivity, the heat exchange surface area of ​​the heat exchange device is increased.

[0088] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0089] This application provides the following technical solutions:

[0090] A fin forming device includes a forming table 1, which is a truncated table with a horizontally arranged table top, and the forming table 1 is rotatable; two working stations are symmetrically arranged on the table top of the forming table 1, one of which is a forming station and the other is a blanking station; a forming module 3 is respectively arranged on the forming station and the blanking station, and the forming module 3 is used as a lower mold during fin forming and stamping. A punching assembly 4 is fixedly arranged directly above the forming station of the forming table 1, and the punching assembly 4 can punch and cut the material on the forming module 3 at the same time. The forming station and the blanking station here belong to the concept of space, and do not specifically refer to a fixed position on the forming table 1. A blanking mechanism 7 is also arranged on one side of the blanking station of the forming table 1, and the blanking mechanism 7 is used to discharge the processed fins. As Figure 1 As shown, because the forming table 1 is rotating, the two forming modules 3 thereon rotate along with it, and the positions of the punching assembly 4 and the unloading mechanism 7 remain unchanged. After the forming table 1 rotates, the position of the forming module 3 located below the punching assembly 4 is the forming station of the forming table 1. Conversely, the position of the forming module 3 located on one side of the unloading mechanism 7 is the unloading station of the forming table 1.

[0091] The punching assembly 4 realizes both punching and cutting actions at the same time, so the punching assembly 4 includes a cutting module 41 and a punching module 42. The cutting module 41 can move in the vertical direction toward or away from the forming module 3 on the forming station of the forming table 1; the cutting module 41 includes a cutting knife 412, which can cut the edge of the metal strip as the material; the cutting knife 412 is located on the side of the forming module 3 below it away from the unloading mechanism 7. The punching module 42 and the cutting module 41 are slidably connected in the vertical direction; the punching module 42 is used as the upper die during the fin forming punching; the cutting knife 412 of the cutting module 41 is located outside the punching module 42.

[0092] When the equipment is in use, the metal strip is loaded on the side close to the punching assembly 4. The loading process can be carried out manually or automatically with existing equipment according to the situation. The metal strip is transported to the top of the forming module 3 of the forming station by loading. The punching assembly 4 cooperates with the forming module 3 to punch the metal strip, complete the stamping forming of the fin, and cut the metal strip at the same time, thereby solving the technical problem that traditional equipment cannot be directly formed by stamping equipment, and achieving the technical effect of stamping and automatically cutting the metal strip.

[0093] On the basis of the above implementation scheme, as the supporting structure of the relevant components of this solution, this solution is provided with a supporting assembly 2, which includes a lower bracket 21 and an upper bracket 22. The lower bracket 21 is used to support the forming table 1, including a bottom frame and an annular shield surrounding the bottom of the forming table 1. The upper bracket 22 extends to the top of the forming table 1 to form a "door"-shaped structure; the punching assembly 4 is movably connected to the upper bracket.

[0094] As a power source for the punching assembly 4, the present solution is further provided with a first driving assembly 5, which includes a hydraulic cylinder 51, a cylinder body of which is fixedly arranged on the upper bracket 22, and a movable end of the hydraulic cylinder 51 is linked with the punching assembly 4 to drive the punching assembly 4 to move up and down to perform punching and cutting actions.

[0095] Based on the above implementation scheme, see Figure 6 As the driving force for the rotation of the forming table 1, the present solution is provided with a second driving assembly 6 below the tabletop of the forming table 1. The second driving assembly 6 includes a motor 63, whose motor shaft is linked to the forming table 1, and the motor 63 can drive the forming table 1 to rotate. The second driving assembly 6 also includes an ejection assembly 62, which is used to eject the processed fins from the forming module 3. The ejection assembly 62 is located below the forming table 1 when not in operation, and the ejection assembly 62 can move upward through the forming table 1 and the forming module 3. Because the ejection is performed only after the processing of the fins is completed, the corresponding position of the upward movement of the ejection assembly 62 is the unloading station of the forming table 1.

[0096] Based on the above implementation scheme, see Figure 5 The molding module 3 is a block structure as a whole, and is provided with a molding groove 31, which is a rectangular groove, and its groove is opened toward the punching assembly 4; a plurality of partitions 32 are arranged in the molding groove 31, and a spacing is left between two adjacent partitions 32; the continuous interval formed by the partitions 32 serves as the stamping lower die molding structure of the fin. An ejection hole 321 is provided on the partition 32, and the ejection hole 321 is a vertical through hole that passes through the molding module 3 and the molding table 1 downward, and the ejection assembly 62 passes through the ejection hole 321 to eject the finished fin.

[0097] Based on the above implementation scheme, see Figure 2 and Figure 3 The cutting module 41 of the punching assembly 4 of this scheme also includes a cutting connecting plate 413, whose plate body is parallel to the forming table 1, and one side of the cutting connecting plate 413 is fixedly connected to the cutting knife 412; the movable end of the hydraulic cylinder 51 of the first driving assembly 5 is fixedly connected to the upper side of the cutting connecting plate 413.

[0098] The punching assembly 4 also includes a guide rod group 43, which includes four guide rods. The guide rods are arranged in the vertical direction. The upper parts of the guide rods pass through the upper bracket 22 and are slidably connected to the upper bracket 22; the rod bodies of the guide rods are fixedly connected to the corners of the cutting connecting plate 413; the guide rods pass through the cutting connecting plate 413 and extend downward.

[0099] The stamping module 42 includes a stamping connecting plate 423, which is parallel to the cutting connecting plate 413 and is arranged below the cutting connecting plate 413; the corner of the stamping connecting plate 423 is slidably connected to the guide rod in the guide rod group 43. A plurality of stamping heads 421 are arranged on the lower side of the stamping connecting plate 423, and the number of the stamping heads 421 is one more than the number of the partitions 32; the stamping heads 421 are arranged corresponding to the concave position on the forming module 3, that is, the area between two adjacent partitions 32.

[0100] A cutting slide rail 411 is fixedly connected to one side of the punching connecting plate 423 . The cutting slide rail 411 is a track in a vertical direction. The cutting knife 412 is slidably connected to the cutting slide rail 411 .

[0101] Through the structure of this solution, when stamping, the hydraulic cylinder 51 drives the cutting link plate 413 to move downward, and the guide rod group 43 moves downward synchronously. At this time, the stamping module 42 is located at the lower end of the guide rod group 43 under the action of its own gravity. When the stamping module 42 contacts the metal strip on the forming module 3, the stamping module 42 remains in place. As the hydraulic cylinder 51 continues to drive the cutting link plate 413 to descend, the stamping link plate 423 slides along the guide rod, and the cutting link plate 413 approaches the stamping link plate 423. After the cutting link plate 413 contacts the stamping module 42, it is pressed down, and the punch head 421 cooperates with the forming groove 31 and the partition plate 32 to stamp the metal strip. During the descent of the cutting module 41, the blade at the bottom of the cutting knife 412 contacts the metal strip, and then moves along the stamping module 42 under the action of the slide rail 411. As the cutting link plate 413 descends, the cutting knife 412 cuts the stamped metal strip.

[0102] Based on the above implementation scheme, see Figure 3 and Figure 4Each punch head 421 includes two oppositely disposed forming plates 4211, with a spacing between the two forming plates 4211; the spacing between the forming plates 4211 forms an insertion channel 4212, the width of the upper end of the insertion channel 4212 is greater than the width of the lower end, and the longitudinal section of the insertion channel 4212 is an inverted triangle structure.

[0103] The punching assembly 4 also includes an insert plate 44, one of which is provided corresponding to the insertion channel 4212 of each punch head 421, and the upper end of the insert plate 44 is fixedly connected to the lower side of the cutting connecting plate 413; a slideway is provided on the punching connecting plate 423 corresponding to the insert plate 44. The shape of the insert plate 44 is the same as that of the insertion channel 4212.

[0104] When the stamping module 42 just contacts the metal strip, the plug plate 44 does not enter the insertion channel 4212. As the cutting connecting plate 413 continues to descend, the cutting connecting plate 413 pushes the plug plate 44 into the insertion channel 4212. The plug plate 44 supports the corresponding two forming clamps 4211 inside, because the plug plate 44 and the insertion channel 4212 adopt exactly the same shape and size. Therefore, after the plug plate 44 enters the insertion channel 4212, the forming clamps 4211 will be slightly opened. In this state, the stamping is carried out in cooperation with the forming module 3 to ensure that the punching head 412 has sufficient strength. When the stamping is completed, the cutting connecting plate 413 drives the plug plate 44 to rise first, so that the plug plate 44 is separated from the forming clamps 4211. The two forming clamps 4211 lose their internal support force and can easily separate from the fins, which can prevent the stamped fins from being stuck on the stamping module 42.

[0105] On the basis of the above implementation scheme, the second driving component 6 also includes a linkage mechanism, which is linked to the punching component 4. When the punching component 4 punches the forming module 3 on the forming station, the linkage mechanism can drive the ejection component 62 to eject the processed fins on the forming module 3 at the unloading station to the unloading mechanism 7.

[0106] See also Figures 6 to 8 The linkage mechanism includes a linkage member 61, which is a bent plate, including an intermediate plate horizontally arranged below the forming table 1, a first vertical plate as a trigger end 611 is arranged at one end of the intermediate plate, and a second vertical plate as a linkage end 612 is arranged at the other end. The trigger end 611 can penetrate the forming table 1 and the forming module 3 from bottom to top, and the linkage end 612 and the trigger end 611 rise or fall synchronously; the linkage end 612 and the ejection assembly 62 at the unloading station are linked, and when the linkage end 612 falls, the ejection assembly 62 located below the unloading station rises to push the finished fin away from the forming module 3.

[0107] Correspondingly, a triggering slot 311 is provided on the molding module 3. The triggering slot 311 is a through slot, which is arranged at the bottom of the molding slot 31. The triggering end 611 of the linkage member 61 can pass through the triggering slot 311.

[0108] In order to achieve the effect of continuous automatic processing, this solution links the stamping action and the ejection action, performs stamping processing at the stamping station, and performs ejection and unloading at the unloading station.

[0109] On the basis of the above embodiment, the ejection assembly 62 includes four ejection rods 621, and the ejection rods 621 correspond to the ejection holes 321 on the molding module 3. A connection frame 622 of a rectangular frame structure is provided at the lower end of the ejection rods 621, and the four corners of the connection frame 622 are respectively fixedly connected to the lower ends of the four ejection rods 621. In order to facilitate the separation of the fins and the ejection rods 621, a ball 623 is provided at the upper end of the ejection rods 621.

[0110] A reset member 613 is provided between the linkage member 61 and the forming table 1. The reset member 613 is a spring. The reset member 613 can reset the linkage member 61. Under normal conditions, the trigger end 611 of the linkage member 61 can be inserted upward into the forming module 3 of the forming station. During stamping, the reset member 613 is deformed by force. The reset member 613 can be implemented in various forms, which is not the key point of this solution and will not be described in detail here.

[0111] In order to realize the linkage of the stamping at the forming station and the ejection at the unloading station. A main linkage frame 64 and a secondary linkage frame 65 are arranged between the motor 63 and the forming table 1. The upper end of the main linkage frame 64 is fixedly connected to the forming table 1, and the main linkage frame 64 can rotate under the drive of the motor 63, thereby driving the forming table 1 to rotate. The axis direction of the main linkage frame 64 is the vertical direction. The middle part of the secondary linkage frame 65 is rotatably connected to the main linkage frame 64, and the axis direction of the two rotating shafts is the horizontal direction. Figure 8 and Fig. 9 The secondary linkage frame 65 includes a connecting plate 651. The middle part of the connecting plate 651 is rotatably connected to the main linkage frame 64, and the connecting plate 651 presents a structure similar to a seesaw. The two ends of the connecting plate 651 are movably connected to a connecting frame 622. A sliding rod 652 is arranged in parallel on both sides of the connecting plate 651, and a slider 653 is slidably connected to the sliding rod 652. The slider 653 needs to have enough dead weight to drive the connecting plate 651 to rotate after its position is offset.

[0112] A plurality of connection slots are provided on the connection frame 622, and connection shafts 654 are provided at both ends of the connection plate 651, which are connected through the connection shafts 654 and the connection slots of the connection frame 622. Fig. 9The direction is for reference, the connection slots include straight slots 6221 opened on both sides of the two connection frames 622, and the ends of the two outer straight slots 6221 are opened with oblique slots 6222, and each set of straight slots 6221 is slidably connected to the aforementioned connection shaft 654.

[0113] When stamping, the trigger end 611 drives the entire linkage part 611 to move downward, and the linkage end 612 pushes the secondary linkage frame 65 below it, so that the slide bar 652 tilts, and the slider 653 deviates on the slide bar 652, further deflecting the secondary linkage frame 65. The connecting shaft 654 first slides in the corresponding two straight openings 6221, driving the corresponding ejector rod to rise along the through hole 321, pushing the stamped fin to move upward, and then one end of the connecting shaft 654 moves to the corresponding oblique opening 6222, so that the two ejector rods on the inner side are higher than the two ejector rods on the outer side, and then the fin can slide along the ball 621 to complete the ejection.

[0114] Based on the above implementation scheme, see Fig.10 An annular inclined platform 111 is provided on the lower bracket 21, and the upper surface of the inclined platform 111 is an inclined transition surface. Its function is that after the unloading is completed, in conjunction with the rotation of the forming table 1, the inclined platform 111 pushes the auxiliary linkage frame 65 at the lower side to restore it to its initial state.

[0115] Based on the above implementation scheme, see Fig.10 The unloading mechanism 7 includes an unloading platform 71, one side of which is fixedly arranged on the outer side of the forming platform 1, and a plurality of unloading rollers 72 are rotatably arranged on the top of the unloading platform 71. After a group of ejection components 62 close to the unloading mechanism 7 eject the punched fins, the fins slide onto the unloading platform 71 and slide along the unloading rollers 72 to complete the unloading.

[0116] On the basis of the above embodiment, a plurality of protrusions are arranged on the lower edge of the plug plate 44, and the lower end of the protrusions is a pointed tip. A plurality of notches are arranged on the molding module 3 corresponding to the protrusions.
