Description
Technical Field
[0001] The present invention relates to the technical field of heat exchange, and its name is a production device for aluminum tube fins of a heat exchanger. Background Art
[0002] A dryer is a cleaning household appliance that uses electric heating to instantly evaporate and dry the moisture in the washed clothes. In a dryer, a heat exchanger is essential. During the manufacturing process of the heat exchanger, the heat dissipation fins are usually directly punched and then press-fitted onto the outside of the heat dissipation aluminum tube with an interference fit to improve the heat dissipation efficiency of the heat exchanger.
[0003] However, currently, the blanking process of the fins and the assembly work of the fins and the aluminum tube are usually processed separately. Usually, after punching multiple fins with a stamping device, the fins are transported to the assembly process, and then are sequentially snap-connected to the outside of the aluminum tube through an interference connection. The assembly efficiency is slow, and it is impossible to simultaneously snap-connect and install multiple layers of fins, and it is impossible to ensure the uniform spacing between multiple layers of fins to ensure uniform heat dissipation between the fins.
[0004] Therefore, it is necessary to provide a production device for aluminum tube fins of a heat exchanger, which can achieve the function of automatic assembly. Summary of the Invention

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, the blanking component continuously punches the conveyed strip to process the fin body, and sends it into the stacking component, where it falls on the upper side of the two rows of stacked wedge parts. The wedge parts on both sides support it. Then, the pressing component on the upper side presses downward, pressing the fin body downward along the inclined surfaces of several wedge parts, causing the wedge parts on both sides to be pushed outwards in sequence from top to bottom. And because there is an elastic part on one side of the wedge part, each pair of wedge parts can quickly reset after being pushed open in sequence. When the pressing component rises and resets, the pressed fin body can be stuck in the middle side of the wedge part for positioning. In this way, through several pairs of sequentially stacked wedge parts, several fin bodies are correspondingly clamped, and there is a certain distance between the fin bodies. When they are clamped with the long U-shaped tube, a uniform clamping distance can still be maintained, so that the heat dissipation performance of each fin body is uniform. The lower side of the stacking component fixes several long U-shaped tubes through the fixing component, and then drives several fin bodies in the stacking component to move downward through the clamping component, so as to be clamped with the long U-shaped tube, realizing the installation of multiple fins at one time with high working efficiency. Then, through the rotation of Gear 1 in the reverse component, the two rack parts are driven to move in the reverse direction respectively, so that the two rows of wedge parts move outward at the same time, canceling the clamping state of several fin bodies. Then, driven by the clamping component, it resets and performs the next round of assembly work. BRIEF DESCRIPTION OF THE DRAWINGS

Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or reference letters in different examples.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.
[0046] Please refer to Figure 1-8 , the present invention provides a technical solution: an aluminum tube fin production device for a heat exchanger, comprising a feeding part 7, a winding part 8, a fixing component 6, a blanking component 3, a stacking component, a pressing component 5, a clamping component 2 and a reverse component 4; wherein,
[0047] The feeding part 7 is used for continuously transporting a strip into the blanking component 3.
[0048] The blanking component 3 is arranged at the middle position between the feeding part 7 and the winding part 8, and the blanking component 3 is used for continuously blanking out fin bodies 9 and feeding them into the stacking component.
[0049] The winding part 8 is used for continuously winding the waste strip after blanking.
[0050] The pressing component 5 is arranged directly above the stacking component, and the pressing component 5 is used for sequentially pressing the fin bodies 9 downward into the stacking component.
[0051] The stacking component includes several groups of wedge parts, two L-shaped plates 103 and an elastic part. The wedge parts are stacked in sequence and are arranged in two opposite columns. The inclined surfaces of the wedge parts face upward and the two columns are arranged oppositely. The two L-shaped plates 103 respectively support the two columns of wedge parts. The elastic part is used to push the wedge parts to reset. A single pair of wedge parts is used to clamp and position a single fin body 9.
[0052] The fixing component 6 is arranged directly below the stacking component, and the fixing component 6 is used to fix several groups of vertically arranged long U-shaped tubes.
[0053] The stacking component is located inside the clamping component 2, and the clamping component 2 is used to drive the stacking component to move up and down for the mutual clamping of the fin bodies 9 and the long U-shaped tubes.
[0054] The reverse component 4 includes two rack parts and a gear 401. The two rack parts are arranged oppositely on both sides of the gear 401. The two rack parts are respectively connected to the two columns of wedge parts. The two rack parts are simultaneously engaged with the gear 401 and drive the two columns of wedge parts to move in opposite directions.
[0055] Specifically, the tape is transported by the loading section 7. The punching assembly 3 continuously punches the transported tape to process the fin body 9. After punching, the waste tape is wound up and recycled by the winding section 8. The processed fin body 9 is sent into the stacking assembly and falls on the upper side of the wedge sections stacked in two columns. The wedge sections on both sides support the fin body 9. Then, it is pressed downward by the pressing assembly 5 above, and the fin body 9 is pressed downward along the inclined surfaces of several wedge sections, causing several wedge sections on both sides to be pushed outward in sequence from top to bottom. And because there is an elastic part on one side of the wedge section, each pair of wedge sections will quickly reset after being pushed open in sequence. After the pressing assembly 5 rises and resets, the downward-pressed fin body 9 can be stuck in the middle of the wedge section for positioning. In this way, several fin bodies 9 are correspondingly stuck by several pairs of sequentially stacked wedge sections, and there is a certain spacing between the fin bodies 9, so that when they are clamped with the long U-shaped tube, a uniform clamping distance can still be maintained, making the heat dissipation performance of each fin body 9 uniform. The lower side of the stacking assembly fixes several long U-shaped tubes through the fixing assembly 6, and then drives several fin bodies 9 in the stacking assembly to move downward through the clamping assembly 2, so as to be clamped with the long U-shaped tube, realizing the installation of multiple fins at one time, with high working efficiency. Then, the gear 401 in the reversing assembly 4 rotates to drive the two rack parts to move in the reverse direction respectively, so that the two columns of wedge sections move outward at the same time, canceling the clamping state of several fin bodies 9, with high automation. Then, it can be driven by the clamping assembly 2 to rise and reset to perform the next round of assembly work, realizing the integrated processing and production of the fin body 9 from forming to assembly, with high working efficiency, and ensuring the uniform gap between each fin body 9 after assembly, ensuring heat dissipation uniformity.
[0056] The wedge section includes a trapezoidal wedge bar 1 and a clamping bar 101. The clamping bar 101 is fixed at the upper end of the trapezoidal wedge bar 1. Several groups of telescopic rods 102 are arranged on one side of the trapezoidal wedge bar 1. One end of the telescopic rod 102 is connected to the L-shaped plate 103. The elastic part is arranged between the L-shaped plate 103 and the trapezoidal wedge bar 1. The clamping bar 101 is also arranged on the inner side of the L-shaped plate 103.
[0057] The elastic part includes a resisting plate 104. One side of the resisting plate 104 is in contact with several groups of trapezoidal wedge bars 1. Two telescopic rods are arranged on the other side of the resisting plate 104. The telescopic rods are connected to the L-shaped plate 103. A first spring 105 is arranged on the outer side of the telescopic rods. The two ends of the first spring 105 are respectively connected to the L-shaped plate 103 and the resisting plate 104.
[0058] Specifically, a number of pairs of trapezoidal wedge blocks 1 are assembled and stacked by the L-shaped plates 103 on both sides. When the first fin body 9 falls onto the wedge part, the fin body 9 is located in the middle of the two clamping bars 101 on the top layer, and the lower side is in contact with the inclined surface of the trapezoidal wedge block 1. When the upper pressing assembly 5 presses down, it pushes the fin body 9, and along the inclined surfaces of the trapezoidal wedge blocks 1 on both sides, it moves downward, causing the trapezoidal wedge blocks 1 to move to both sides, so that the fin body 9 falls into the clamping state of the lower layer of trapezoidal wedge blocks 1 and clamping bars 101. The upper trapezoidal wedge blocks 1 return to their original positions under the reset action of the elastic part, and so on, until the fin body 9 is pushed to the bottom L-shaped plate 103 and is limited by the clamping bars 101 on both sides, that is, the installation of the first fin body 9 is completed. The subsequent fin bodies 9 are pressed down according to this principle. Each fin body 9 is clamped by the clamping bars 101 of each layer and is limited by the upper and lower trapezoidal wedge blocks 1, so that they all maintain a uniform spacing for the subsequent unified clamping by the clamping assembly 2;
[0059] By arranging a pressing plate 104 on one side of a number of trapezoidal wedge blocks 1, and arranging a second telescopic rod and a first spring 105 on one side of the pressing plate 104, the pressing plate 104 is always pressed against a number of trapezoidal wedge blocks 1, achieving the effect that one pressing plate 104 can reset a number of groups of trapezoidal wedge blocks 1, avoiding setting a separate spring piece for each group of trapezoidal wedge blocks 1 to reset and increasing the cost.
[0060] The clamping assembly 2 includes a square frame 201. The inner ends of both sides of the square frame 201 are in contact with the L-shaped plates 103. Four corners of the square frame 201 are fixedly connected with guide sleeves 202. A guide post 203 is slidably fitted inside the guide sleeve 202. The lower end of the guide post 203 is fixedly connected with a base 204. The upper end of the guide post 203 is fixedly connected with a top plate 205. The upper end of the guide sleeve 202 is fixedly connected with a lifting plate 206. One side of the lifting plate 206 is threadedly connected with a first threaded rod 207. The lower end of the first threaded rod 207 is rotatably connected with the base 204. The upper end of the first threaded rod 207 passes through the top plate 205 and is rotatably connected with it.
[0061] Specifically, the square frame 201 is in contact with the two L-shaped plates 103, thereby limiting the other two sides of a number of fin bodies 9 except those restricted by the wedge part. When the first threaded rod 207 rotates, the first threaded rod 207 is threadedly connected with the lifting plate 206. Under the guiding action of the four guide posts 203 and guide sleeves 202, the lifting plate 206 drives the guide sleeve 202, the square frame 201 and the stacking assembly to move downward to perform the clamping work on a number of fin bodies 9.
[0062] The two rack parts include rack one 402 and rack two 403. Two square openings are provided on one side of the square frame 201. The first gear 401 is rotatably connected to the central position on one side of the square frame 201. The first gear 401 is driven to rotate by a motor component. The lower side of the first gear 401 meshes with the rack one 402. One side of the rack one 402 is fixedly connected with a sliding plate one 404. The sliding plate one 404 is fixedly connected to the lower end of the L-shaped plate 103 on one side. The sliding plate one 404 slides in the square opening. The upper side of the first gear 401 meshes with the rack two 403. One side of the rack two 403 is fixedly connected with a sliding plate two 405. The sliding plate two 405 is fixedly connected to the upper end of the L-shaped plate 103 on the other side. The sliding plate two 405 slides in the square opening.
[0063] One end of the outer side of each of the two L-shaped plates 103 is fixedly connected with a plurality of reset rods 406. The outer end of the reset rod 406 is fixedly connected with a disc 408. The reset rod 406 passes through the square frame 201 and is in sliding fit with it. A second spring 407 is arranged on the outer side of the reset rod 406. The two ends of the second spring 407 are respectively connected to the square frame 201 and the L-shaped plate 103.
[0064] Specifically, when a plurality of fin bodies 9 are all clamped on the long U-shaped tube, at this time, the trapezoidal wedge block strip 1 and the clamping strip 101 need to release the restriction on the plurality of fin bodies 9. Since the first gear 401 meshes with the rack one 402 and the rack two 403 respectively and simultaneously, the rack one 402 is arranged at the lower end of the first gear 401, and the rack one 402 is connected to the sliding plate one 404 and the left L-shaped plate 103 (as Figure 5 shown), while the rack two 403 is arranged at the upper end of the first gear 401 and is similarly connected to the right L-shaped plate 103. Therefore, when the motor component drives the first gear 401 to rotate, the first gear 401 simultaneously drives the rack one 402 and the rack two 403 to move in opposite directions, so that the two L-shaped plates 103 move in opposite directions, that is, move to both sides, thereby driving the wedge block parts on both sides to move away from each other, and the restriction on the plurality of fin bodies 9 can be released, and then the clamping assembly 2 is used to lift upward for resetting;
[0065] After resetting, under the reset action of the second spring 407, the L-shaped plate 103 and a plurality of wedge block parts return to their original positions. The reset rod 406 performs reset guiding, and contacts the outer side of the square frame 201 through the disc 408. The reset is completed, which is convenient for the next round of installation of the fin bodies 9.
[0066] The pressing assembly 5 includes two pressing bars 501. The lower side of the pressing bar 501 corresponds to the inclined surface of the wedge block part. The upper end of the pressing bar 501 is fixedly connected with a vertical plate 502, and the upper end of the pressing bar 501 is fixedly connected with a partition plate 503. A number of third telescopic rods 504 are arranged at the upper end of the partition plate 503. The upper end of the third telescopic rod 504 is connected with the top plate 205. A first threaded sleeve 505 is arranged at the upper end of the partition plate 503. A short threaded rod 506 is threadedly connected inside the first threaded sleeve 505. The short threaded rod 506 penetrates through the top plate 205 and is rotatably connected with it.
[0067] Specifically, two pressing bars 501 are provided to press the stacking assembly. The pressing bar 501 corresponds to the inclined surface of the wedge block part. When the pressing bar 501 is pressed down, the pressure borne by the fin body 9 is reduced, and deformation is reduced. By threadedly connecting the short threaded rod 506 with the first threaded sleeve 505, under the guiding action of a number of third telescopic rods 504, when the short threaded rod 506 rotates, the first threaded sleeve 505 drives the partition plate 503 and the pressing bar 501 to descend for pressing work. And a vertical plate 502 is arranged on one side of the pressing bar 501. When the pressing bar 501 presses the fin body 9 to the lower side of the wedge block part, the vertical plate 502 contacts and abuts against a number of upper wedge block parts to prevent the pressing bar 501 from being stuck in the wedge block part.
[0068] The upper end of the short threaded rod 506 is fixedly connected with a second gear 507. A driving gear part is meshed and connected to one side of the second gear 507. A first motor 508 is arranged at the lower end of the driving gear part. The first motor 508 is fixed to the lower end of the top plate 205. A number of first electromagnets 509 are fixedly connected to the upper side of the partition plate 503. The first threaded sleeve 505 is made of magnetic metal. The lower end of the first threaded sleeve 505 is rotatably connected with the partition plate 503. The upper end of the driving gear part is fixedly connected with a first pulley 510. A belt is connected to one side of the first pulley 510 and connected to a second pulley 511. The lower end of the second pulley 511 is connected with a first threaded rod 207. A second threaded sleeve 512 is threadedly connected to the outer side of the first threaded rod 207. The second threaded sleeve 512 is made of magnetic metal. The outer side of the second threaded sleeve 512 is rotatably connected with a second electromagnet 513. The second electromagnet 513 is fixed inside the lifting plate 206.
[0069] Specifically, when the second electromagnet 513 is powered off and the first electromagnet 509 is powered on, the first electromagnet 509 is connected to the first threaded sleeve 505, so that the first threaded sleeve 505 and the partition 503 are connected as a whole. Then, the first motor 508 drives the rotation of the driving gear assembly, and the driving gear assembly meshes with the second gear 507, thereby driving the rotation of the short threaded rod 506. Under the guiding action of the third telescopic rod 504, the pressing assembly 5 is driven to move, and the pressing work can be started. On the contrary, when the first electromagnet 509 is powered off and the second electromagnet 513 is in the powered-on state, the first threaded sleeve 505 is disconnected from the first electromagnet 509, and the first threaded sleeve 505 rotates relative to the partition 503. At this time, the short threaded rod 506 drives the first threaded sleeve 505 to rotate on its own, and the pressing assembly 5 cannot be driven to move. At this time, the driving gear assembly drives the rotation of the first threaded rod 207 through the belt drive of the first belt pulley 510 and the second belt pulley 511. The lifting plate 206 and the second threaded sleeve 512 are connected as a whole by the energized second electromagnet 513. Under the guiding action of the guide post 203, the first threaded rod 207 drives the lifting plate 206 to move, and the clamping assembly 2 can be driven to move for clamping work. That is to say, by alternately energizing and powering off the first electromagnet 509 and the second electromagnet 513, the first motor 508 drives the pressing assembly 5 and the clamping assembly 2 in an orderly manner, achieving the effect of a single motor driving two functional components, saving redundant motor costs.
[0070] The fixing component 6 includes a fixing base 601 which is fixed to the inner side of the base 204. A plurality of groups of special-shaped holes 602 are formed in the upper side of the fixing base 601. There are three rows of the plurality of groups of special-shaped holes 602. Each single special-shaped hole 602 is used for clamping a single long U-shaped tube. A plurality of support columns 603 are arranged inside the special-shaped hole 602. The support columns 603 are in clearance fit with the holes of the long U-shaped tube. At both ends of the lower side of the fixing base 601, there are fixedly connected with fixing plates 604. Inside the fixing plates 604, there is rotatably connected a second threaded rod 605. On the outer side of the second threaded rod 605, there are successively arranged a first moving block 606, a second moving block 607, a third moving block 608 and a fourth moving block 609. The upper sides of the first moving block 606, the second moving block 607, the third moving block 608 and the fourth moving block 609 are all fixedly connected with the plurality of support columns 603. The first moving block 606, the second moving block 607, the third moving block 608 and the fourth moving block 609 are all in sliding fit with the fixing base 601. The second threaded rod 605 passes through the first moving block 606 and the third moving block 608 and is threadedly connected therewith. The second threaded rod 605 passes through the second moving block 607 and the fourth moving block 609 and is in clearance fit therewith. Inside the fixing plates 604, there is rotatably connected a third threaded rod 610. The third threaded rod 610 is simultaneously threadedly connected with the second moving block 607 and the fourth moving block 609 and is in clearance fit with the first moving block 606 and the third moving block 608. One end of the third threaded rod 610 is fixedly connected with a third gear 612. One end of the second threaded rod 605 is fixedly connected with a fourth gear 611. The third gear 612 meshes with the fourth gear 611. The second threaded rod 605 is driven to rotate by a motor assembly.
[0071] Specifically, three rows of special-shaped holes 602 are formed in the fixing base 601, and a clamping block 615 is further arranged in the middle of the special-shaped holes 602 in the middle row. When the long U-shaped tubes need to be fixed, the staff only needs to first insert the pipe orifices of the plurality of long U-shaped tubes into the corresponding special-shaped holes 602 and sleeve them on the outer sides of the corresponding support columns 603. The second threaded rod 605 is driven to rotate by the motor assembly. Under the guiding action of the third threaded rod 610, the first moving block 606 and the third moving block 608 move to the left simultaneously, so that the upper support columns 603 drive the long U-shaped tubes to move together, making the long U-shaped tube on the first moving block 606 be clamped with the left side of the fixing base 601. The two rows of support columns 603 on the third moving block 608 move, one row is clamped with the clamping block 615, and the other row is also clamped with the fixing base 601. The third threaded rod 610 meshes with the second threaded rod 605 through the third gear 612 and the fourth gear 611 and rotates in the opposite direction to the second threaded rod 605, so that the second moving block 607 and the fourth moving block 609 move to the right, thereby driving the remaining support columns 603 to move in the opposite direction, and also cooperating with the clamping block 615 and the fixing base 601 to fully clamp the long U-shaped tubes, improving the stability of the long U-shaped tubes when being clamped with the fin body 9.
[0072] One end of the moving block 606 close to the moving block 607 is fixedly connected with a limiting block 613, and one end of the moving block 609 close to the moving block 608 is fixedly connected with a limiting block 614.
[0073] Specifically, the limiting block 613 and the limiting block 614 are provided. When it is necessary to remove the installed long U-shaped tube and the fin body 9, the motor assembly is made to drive the threaded rod 605 to reverse, so that the four moving blocks perform a reset movement. At this time, the limiting block 613 and the limiting block 614 are stuck between the two groups of moving blocks, preventing them from over-resetting and causing the distance between the support column 603 and the special-shaped hole 602 to be too small, affecting the subsequent inability of the long U-shaped tube to be inserted into the support column 603.
[0074] The blanking assembly 3 includes an upper die 301 and a lower die 302. The upper die 301 is driven to move by a hydraulic mechanism, and the hydraulic mechanism is fixed on the top plate 205. A plurality of fixed columns 305 are fixedly connected to the lower end of the lower die 302, and the fixed columns 305 are fixed on the base 204. A push block 303 is arranged inside the lower die 302. One end of the push block 303 is fixedly connected with a push rod 304. The push rod 304 penetrates through the lower die 302 and is slidably matched with it. A discharge channel 306 is opened inside the lower die 302. The outside of the discharge channel 306 corresponds to the stacking assembly, and the push rod 304 is driven to move by a cylinder member.
[0075] Specifically, the equipment for processing and producing the fin body 9 is a common existing technology on the market, so it will not be elaborated here. The upper die 301 can be driven to descend by a hydraulic mechanism, and the fin body 9 can be blanked and formed in cooperation with the lower die 302. After that, the blanked fin body 9 is located inside the lower die 302. At this time, the push rod 304 and the push block 303 are pushed to move by the cylinder member, and the fin body 9 is pushed outwards from the discharge channel 306 and pushed into the corresponding stacking assembly to prepare for the clamping work, so as to realize the integrated processing of fin blanking and assembly, with high working efficiency.
