Description

Technical Field

[0001] The invention relates to the technical field of heat exchange component manufacturing, and in particular to a heat exchange fin forming machine for manufacturing heat exchange components. Background Art

[0002] A heat exchange component is a device used to achieve heat transfer. Common heat exchange components include shell and tube heat exchangers, shell and tube heat exchangers, plate heat exchangers, and fin heat exchangers. Heat exchange fins are a device used to enhance heat exchange efficiency. They are usually made of metal sheets and installed on the surface of the heat exchanger. Their function is to increase the heat exchange area of ​​the heat exchanger, improve the heat exchange efficiency, and enable heat to be transferred more efficiently. The shape and structure of the fins can be designed and optimized according to different application requirements. Common fin shapes include flat fins, corrugated fins, window fins, etc. The material of the fins usually has good thermal conductivity, such as aluminum, copper, etc.

[0003] Publication No.: CN213134818U discloses a feeding device of a heat exchanger fin stamping and forming machine. When the feeding device of the heat exchanger fin stamping and forming machine is in use, the fan draws out the air in the vacuum box through the air duct, and there is negative pressure in the vacuum box and the outside world. The fins are continuously moved from one end of the feeding plate to the feeding plate, and at the same time, the fins are adsorbed on the feeding plate through the air holes using the negative pressure of the vacuum box. When the fins are completely on the feeding plate and some of the sheet holes on the fins correspond to the limit rods, the damper is driven to rotate by the driving member, the air outlet is opened, the air pressure in the vacuum box is consistent with that in the outside world, the fins fall, the sheet holes on the fins and the limit rods are plugged into each other, and the fins are guided to fall on the placement plate by the limit rods, and the above operation is repeated. The fins are continuously stacked on the placement plate. With this arrangement, the fins are neatly collected on the placement plate, which is beneficial to subsequent transportation, and automatic collection and sorting is beneficial to improving work efficiency.

[0004] However, this device has certain drawbacks when processing heat exchange fins. It is not convenient to effectively cut heat exchange fins of different shapes. This device uses the negative pressure of the vacuum box to adsorb the heat exchange fins on the feed plate through the air holes. It is a relatively mainstream cutting and sorting method at present. However, the shapes of heat exchange fins include flat fins, corrugated fins, window fins, etc. The shapes of heat exchange fins are different, and thus the surface flatness is also different. For example, when this device uses the negative pressure of the vacuum box to adsorb the corrugated fins through the air holes, the surface of the corrugated fins is uneven and there are certain gaps. The negative pressure of the vacuum box cannot effectively adsorb the corrugated fins through the air holes, resulting in the corrugated fins being scattered irregularly after shearing. Manual sorting is required later, but the surface of the processed heat exchange fins is relatively sharp, which can easily scratch gloves and injure fingers, and the efficiency of manual sorting is low.

[0005] Therefore, it is necessary to provide a heat exchange fin forming machine for manufacturing heat exchange components to solve the above technical problems. Summary of the invention

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.

[0022] The invention provides a heat exchange fin forming machine for manufacturing a heat exchange component.

[0023] First embodiment: See also Figures 1 to 8 , a heat exchange fin forming machine for manufacturing heat exchange components, comprising a mounting frame 1, the top of which is provided with a coil conveying device 2, a fin processing device 3 and a shearing mechanism 4 in sequence from back to front; The shearing mechanism 4 includes a mounting seat 41 fixedly arranged on the top front side of the mounting frame 1, a mounting cover 42 fixedly arranged on the top of the mounting seat 41, guide frames 43 fixedly arranged on both sides of the inner wall of the mounting cover 42, shearing seats 44 fixedly arranged on the surfaces of the two guide frames 43, moving seats 45 slidably connected on the surfaces of the two guide frames 43 and located on the top of the shearing seats 44, a shearing tool 46 fixedly arranged on the bottom of the moving seat 45, two rotating seats 47 fixedly arranged on the top of the moving seat 45, cams 48 rotatably connected to the inner sides of the two rotating seats 47, drive shafts 49 transversely arranged on the inner sides of the two cams 48, both ends of the drive shaft 49 are rotatably connected to the inner side of the mounting cover 42, and a drive motor 410 for driving the drive shaft 49 to rotate is arranged on the left side of the mounting cover 42; Please combine Figure 4 : Start the drive motor 410, and the rotation of the drive motor 410 drives the drive shaft 49 to rotate. The rotation of the drive shaft 49 drives the two cams 48 to rotate. During the rotation process, the cam 48 drives the movable seat 45 to move up and down on the surface of the guide frame 43 through the two rotating seats 47. The movable seat 45 moves up and down to reciprocate, thereby driving the shearing tool 46 to move up and down, so that the processed heat exchange fins are sheared by the shearing tool 46 and the heat exchange fins are cut into a fixed size.

[0024] The front side of the mounting cover 42 is fixedly provided with a feeding mechanism 5, and the feeding mechanism 5 includes a feeding frame 51 fixedly provided on the front side of the mounting cover 42, a threaded rod 52 is transversely provided on the inner side of the feeding frame 51, and two sliding seats 53 are slidably connected to the inner side of the feeding frame 51 and located on the surface of the threaded rod 52, and a return spring 54 is sleeved on the surface of the threaded rod 52 and located on the side where the two sliding seats 53 are separated, and a nut 55 is threadedly connected to the surface of the threaded rod 52 and located on the side opposite to the two sliding seats 53, and the inner sides of the tops of the two sliding seats 53 are rotatably connected with a connecting rod 56, and the tops of the two connecting rods 56 are rotatably connected with a pressing seat 57, and the inner side of the pressing seat 57 is threadedly connected with two bolts 58, and a lower pressing frame 59 is fixedly provided on the top of the movable seat 45, and a limiting bracket 510 is fixedly provided at the bottom of the two sliding seats 53, and a fin body 511 is provided on the top of the two limiting brackets 510; Please combine Figures 5 to 8: After the fin body 511 is conveyed to the bottom of the unloading rack 51, the two limit brackets 510 can support the fin body 511. When the movable seat 45 drives the shearing tool 46 to cut downward, the movable seat 45 will simultaneously drive the lower pressing frame 59 to move downward. When the lower pressing frame 59 moves downward, it will first contact the two bolts 58. Then, as the movable seat 45 continues to move downward, the shearing tool 46 will contact the fin body 511 and cut the fin body 511. After the lower pressing frame 59 moves downward and contacts the two bolts 58, as the movable seat 45 continues to move downward, the two bolts 58 will drive The pressing seat 57 moves downward, and the two sliding seats 53 are moved to both sides on the inner side of the unloading rack 51 by the connecting rod 56 through the movement of the pressing seat 57. The two return springs 54 are contracted by the movement of the two sliding seats 53. The two sliding seats 53 will respectively drive the two limiting brackets 510 to move to the separated side during the movement, thereby canceling the support for the fin body 511. When the shearing tool 46 completes the shearing work on the fin body 511, the two limiting brackets 510 will simultaneously cancel the limiting effect on the fin body 511, thereby allowing the sheared fin body 511 to fall freely. Further: when the movable seat 45 drives the shearing tool 46 to complete the shearing of the fin body 511 and drives the shearing tool 46 to move upward, the movable seat 45 will simultaneously drive the lower pressing frame 59 to move upward, and the lower pressing frame 59 will cancel the squeezing of the two bolts 58, and the expansion of the two return springs 54 will drive the two sliding seats 53 to slide to the opposite side on the inner side of the lower material frame 51, and the two sliding seats 53 will then drive the pressing seat 57 and the two bolts 58 to move upward through the two connecting rods 56. When the two sliding seats 53 slide to the opposite side, they will drive the two limiting brackets 510 to move to the opposite side, so that the limiting brackets 510 can be reused to support the fin body 511; Furthermore, by manually rotating the two bolts 58, the height positions of the two bolts 58 can be adjusted, and then the contact time between the two bolts 58 and the lower pressing frame 59 can be adjusted, so that the time for the two limit brackets 510 to move to the separated side can be adjusted, and then the two limit brackets 510 can adapt to fin bodies 511 of different widths, so that the cutting time of the fin body 511 is consistent with the time when the fin body 511 can fall freely; Preferably, the distance between the two sliding seats 53 can be adjusted by screwing the two nuts 55 , and by adjusting the distance between the two sliding seats 53 , the two sliding seats 53 can further adjust the height positions of the pressure seat 57 and the bolt 58 through the two connecting rods 56 .

[0025] The surface of the shearing seat 44 is provided with a groove for use with the shearing tool 46, and the inner side of the movable seat 45 is provided with a through groove for use with the guide frame 43, which can slide up and down on the surface of the guide frame 43. The cam 48 is composed of a convex wheel and an eccentric wheel, and the connection point between the drive shaft 49 and the cam 48 is far away from the center of the eccentric wheel.

[0026] The inner side of the unloading rack 51 is provided with a slide groove for use with the sliding seat 53, which can allow the sliding seat 53 to slide left and right. The inner sides of the two sliding seats 53 are both provided with a through groove for use with the threaded rod 52, and the through groove is a smooth cylindrical shape.

[0027] In this embodiment, different from the existing heat exchange fin blanking structure, when the device of this case is working, the driving motor 410 drives the driving shaft 49 and the cam 48 to rotate, so that the movable seat 45 drives the shearing tool 46 to move downward, and when the fin body 511 is sheared, the movable seat 45 will simultaneously drive the lower pressing frame 59 to move downward, and the lower pressing frame 59 will first contact the two bolts 58 during the movement, and then the shearing tool 46 will subsequently contact the fin body 511, and when the lower pressing frame 59 moves downward and contacts the two bolts 58, as the movable seat 45 continues to move downward, the two bolts 58 will drive the pressing seat 57 to move downward, and then the connecting rod 56 is used to move the two sliding seats 53 to both sides on the inner side of the blanking frame 51. During the movement, the two sliding seats 53 will respectively drive the two limiting brackets 510 to move to the separated side, thereby canceling the support for the fin body 511. When the shearing tool 46 completes the shearing work on the fin body 511, the two limiting brackets 510 will simultaneously cancel the limiting effect on the fin body 511, so that the fin body 511 after shearing can fall freely. Compared with the traditional heat exchange fin blanking structure, this case can effectively blank heat exchange fins of different shapes. There is no need to consider the shape and structure of the heat exchange fins during blanking, so that heat exchange fins of different shapes and structures can be blanked regularly and continuously, which effectively improves the adaptability of the device and avoids the problem of irregular scattering of the heat exchange fins after shearing.

[0028] Second embodiment: See also Figure 3 , Figures 9 to 11The front side of the mounting frame 1 is fixedly provided with a step-by-step descending mechanism 6, and the step-by-step descending mechanism 6 includes two vertical mounting seats 61 fixedly provided on the front side of the mounting frame 1, and the tops of the two vertical mounting seats 61 are fixedly connected to the bottom of the unloading frame 51, and the two vertical mounting seats 61 are horizontally rotatably connected to a rotating shaft 62 on the opposite side, and two first rotating wheels 63 are fixedly provided on the surface of the rotating shaft 62, and the tops of the opposite sides of the two vertical mounting seats 61 are rotatably connected to second rotating wheels 64, and the two first rotating wheels 63 and the two second rotating wheels 64 are divided into two groups, and the surfaces of each group of the first rotating wheels 63 and the second rotating wheels 64 are sleeved with a transmission belt 65; The surfaces of the two transmission belts 65 are fixed with connecting brackets 66, and the two connecting brackets 66 are fixed with moving platforms 67 on opposite sides thereof. Two sliding seats 68 are fixed with the two moving platforms 67 on the separated sides thereof, and two sliding rails 69 are fixed with the two vertical mounting seats 61 on opposite sides thereof. The four sliding seats 68 are slidably connected with the four sliding rails 69, respectively. A base 610 is fixed with the bottom of the two vertical mounting seats 61, and a servo motor 611 for driving the rotating shaft 62 to rotate is arranged on the left side of the left vertical mounting seat 61.

During the rotation process, the two transmission belts 65 will simultaneously drive the two connecting brackets 66 to move downward, and the movement of the two connecting brackets 66 will drive the two moving platforms 67 to move downward, so that the four slides 68 slide downward on the slide rails 69 respectively.

The two first rotating wheels 63 rotate intermittently and then drive the two transmission belts 65 to rotate intermittently, so that the two connecting brackets 66 intermittently drive the two moving platforms 67 to move downward, and the two moving platforms 67 intermittently move downward, so that the placement plate 71 slides intermittently downward on the surface of the placement frame 72; Furthermore, when the shearing tool 46 completes the shearing work on the fin body 511, the two limiting brackets 510 simultaneously cancel the limiting effect on the fin body 511, so that when the sheared fin body 511 falls freely, the falling fin body 511 can be supported by the placement plate 71, and after supporting the fin body 511, the placement plate 71 slides downward on the surface of the placement rack 72 by the distance of the fin body 511 through the intermittent rotation of the servo motor 611, so that the fin body 511 can be stacked on the top of the placement plate 71 in sequence, and the stacked fin body 511 can be limited by the setting of the placement rack 72 to avoid the problem of collapse caused by the fin body 511 being stacked too high; Preferably, when the placement rack 72 is full of fin bodies 511, the placement rack 72 and the placement plate 71 can be moved using the universal wheel 73, and then a new collecting mechanism 7 can be replaced, that is, the sheared fin bodies 511 can be continuously collected.

Through the intermittent rotation of the servo motor 611, the rotating shaft 62 drives the two first rotating wheels 63 and the two transmission belts 65 to rotate intermittently, so that the two connecting brackets 66 intermittently drive the two moving platforms 67 to move downward, so that the placement plate 71 intermittently slides downward on the surface of the placement rack 72 by the height of the fin body 511, and then the fallen fin body 511 can be collected in an orderly manner, so that the fin body 511 can be stored in the placement rack 72 in an orderly manner, and the workers do not need to manually collect and organize the fin body 511, which effectively reduces the workload of the workers and improves the production efficiency of the heat exchange fins.

The rotation of the conveying roller 81 cooperates with the pressure roller 82 to continuously convey the heat exchange fins. Preferably, the first pulley 83 and the second pulley 84 can be replaced. By changing the size of the first pulley 83 and the second pulley 84, the rotation speed of the conveying roller 81 can be controlled, thereby adjusting the conveying speed of the heat exchange fins.

The spring 96 contracts. When the heat exchange fin is located on the opposite side of the fixed limiting plate 93 and the movable limiting plate 98, the movable limiting plate 98 moves to the right, so that the heat exchange fin can be pushed to the right. When the reciprocating bracket 913 moves to the left, the expansion of the squeezing spring 96 is used to make the slider 97 drive the movable limiting plate 98 to move to the left, and the squeezing of the heat exchange fin is cancelled.

[0035] In this embodiment, the driving shaft 49 will drive the first pulley 83 to rotate during the rotation process. The rotation of the first pulley 83 uses the first belt 85 to drive the second pulley 84 and the conveying roller 81 to rotate, so that the heat exchange fins are conveyed by the conveying roller 81. When the conveying roller 81 rotates, it will also drive the third pulley 99 to rotate. The rotation of the third pulley 99 uses the second belt 912 to drive the fourth pulley 911 and the tubular cam 910 to rotate. The rotation of the tubular cam 910 drives the reciprocating bracket 913 to move back and forth, so that the reciprocating bracket 913 repeatedly pushes the movable limit plate 98, so that the movable limit plate 98 and the fixed limit plate 93 are used to limit the moving heat exchange fins to avoid displacement of the heat exchange fins during transportation.

[0036] Please refer to Figures 1 to 17 The working principle of the heat exchange fin forming machine for manufacturing heat exchange components provided by the present invention is as follows: Step S1, firstly, the cylindrical coil is installed on the coil conveying device 2, and then the fin processing device 3 is started to process the coil, and the coil is processed into a continuous heat exchange fin. When the heat exchange fin is processed to a certain length, the heat exchange fin is passed through the middle of the conveying roller 81 and the pressing roller 82, so that the heat exchange fin is on the opposite side of the fixed limit plate 93 and the movable limit plate 98, and the head of the heat exchange fin is placed on the top of the two limit brackets 510, and then the drive motor 410 is started; Step S2, the driving motor 410 is driven to rotate the driving shaft 49, and the driving shaft 49 is driven to rotate the two cams 48. During the rotation process, the cams 48 drive the moving seat 45 to move up and down on the surface of the guide frame 43 through the two rotating seats 47. The moving seat 45 moves up and down to drive the shearing tool 46 to move up and down, so that the heat exchange fins are sheared by the shearing tool 46 to be sheared into a fixed size. Step S3, when the movable seat 45 drives the shearing tool 46 to shear downward, the movable seat 45 will simultaneously drive the lower pressing frame 59 to move downward. When the lower pressing frame 59 moves downward, it will first contact the two bolts 58. Then, as the movable seat 45 continues to move downward, the shearing tool 46 will contact the fin body 511 and shear the fin body 511. After the lower pressing frame 59 moves downward and contacts the two bolts 58, as the movable seat 45 continues to move downward, the two bolts 58 will drive the pressing seat 57 to move downward, and the movement of the pressing seat 57 will further The two sliding seats 53 are moved to both sides on the inner side of the unloading rack 51 by the connecting rod 56. The two return springs 54 are contracted by the movement of the two sliding seats 53. The two sliding seats 53 respectively drive the two limiting brackets 510 to move to the separated side during the movement, thereby canceling the support for the fin body 511. When the shearing tool 46 completes the shearing work on the fin body 511, the two limiting brackets 510 simultaneously cancel the limiting effect on the fin body 511, thereby allowing the sheared fin body 511 to fall freely. When the movable seat 45 drives the shearing tool 46 to complete the shearing of the fin body 511 and drives the shearing tool 46 to move upward, the movable seat 45 will simultaneously drive the lower pressing frame 59 to move upward, and the lower pressing frame 59 will cancel the squeezing of the two bolts 58, and the expansion of the two return springs 54 will drive the two sliding seats 53 to slide to the opposite side on the inner side of the lower material frame 51, and the two sliding seats 53 will then drive the pressing seat 57 and the two bolts 58 to move upward through the two connecting rods 56. When the two sliding seats 53 slide to the opposite side, they will drive the two limiting brackets 510 to move to the opposite side, so that the limiting brackets 510 can be reused to support the fin body 511; Step S4, when the shearing tool 46 completes the shearing work on the fin body 511, and the sheared fin body 511 is in free fall, the falling fin body 511 can be supported and stored by the placement plate 71, and the servo motor 611 is intermittently rotated, and the two first rotating wheels 63 and the two transmission belts 65 are driven to rotate intermittently by the rotating shaft 62, so that the two connecting brackets 66 intermittently drive the two moving platforms 67 to move downward, so that the placement plate 71 intermittently slides downward on the surface of the placement rack 72 by the height of the fin body 511, and then the falling fin body 511 can be collected in an orderly manner, so that the fin body 511 can be orderly stored in the placement rack 72; Step S5, the driving shaft 49 drives the first pulley 83 to rotate during the rotation process, and the first pulley 83 drives the second pulley 84 and the conveying roller 81 to rotate by utilizing the first belt 85, so that the heat exchange fins are conveyed by utilizing the conveying roller 81, and the conveying roller 81 drives the third pulley 99 to rotate at the same time when rotating, and the rotation of the third pulley 99 drives the fourth pulley 911 and the tubular cam 910 to rotate by utilizing the second belt 912, and the rotation of the tubular cam 910 drives the reciprocating bracket 913 to reciprocate, so that the reciprocating bracket 913 repeatedly pushes the movable limit plate 98, so that the movable limit plate 98 and the fixed limit plate 93 are used to limit the moving heat exchange fins; Step S6, when the placement rack 72 is full of fin bodies 511, the placement rack 72 and the placement plate 71 can be moved by using the universal wheel 73, and then a new collecting mechanism 7 is replaced, that is, the sheared fin bodies 511 can be continuously collected.
