[0016] The present invention provides an improved heat exchange fin production device, which has the following beneficial effects:

[0017] 1. In this improved heat exchange fin production device, in addition to two guiding and buffering structures, there are also two die pressing and lifting power structures, namely, the hydraulic lifting structure composed of a hydraulic cylinder and a hydraulic rod and the pneumatic lifting structure where the pneumatic lifting rod is located. Among them, the pneumatic lifting rod serves as the main power part of the upper die part, directly bearing the opening and closing die pressure to ensure that the opening and closing die actions can be carried out smoothly and completely. And the hydraulic lifting structure composed of the hydraulic cylinder and the hydraulic rod serves as the auxiliary power part of the upper die part, and its direct acting object is the top plate. By driving the top plate to move up and down, it assists the upper die part to move up and down stably, providing good assistance for the up and down movement of the upper die part, and avoiding the problems of inconsistent and untimely opening and closing die actions caused by the aging of the production equipment, effectively extending the service life and comprehensive use effect of this improved heat exchange fin production device.

[0018] 2. In this improved heat exchange fin production device, the specific acting object of the guiding mechanism is the top plate, while the specific acting object of the buffering part composed of a buffer insertion channel, a buffer spring and a buffer guide rod is the upper die part. The buffer insertion channel and the buffer guide rod cooperate with each other to ensure that the upper die movable seat can move up and down stably. The buffer spring enables the up and down movement of the upper die movable seat to have a certain recovery performance, which helps the smooth completion of the opening die action after the die is closed. The buffering part composed of the buffer insertion channel, the buffer spring and the buffer guide rod serves as the main guiding and resetting structure of the upper die, effectively ensuring the smooth and continuous progress of the opening and closing die actions. And the guiding mechanism serves as the auxiliary guiding and resetting structure of the upper die, directly and effectively making up for the guiding deviation or untimely die separation caused by wear after the production equipment has been used for a long time.

[0019] 3. In this improved heat exchange fin production device, the guiding mechanism is used for guiding and buffering the up and down movement of the top plate during the opening and closing die process. Among them, the telescopic sleeve structure composed of a guiding tube and a guiding rod can be used for guiding the up and down movement of the top plate. The addition of the guiding spring makes the guiding tube and the guiding rod have good telescopic elasticity. By means of this elasticity, the closing die pressure can be effectively and well buffered, facilitating the smooth and continuous progress of the opening die action, and avoiding problems such as equipment delay or even jamming.

[0020] 4. The improved heat exchange fin production equipment, through the setting of the conveyor belt, makes the entire lower die structure more convenient to control and use. After the conveyor belt starts, it can drive the lower die substrate and the air transmission seat arranged thereon to move positions accordingly, which is convenient for replacing the die, and can quickly adjust the position occupied by the die, enabling the die to be quickly adjusted in position, so that production and processing can be carried out quickly.

[0021] 5. The improved heat exchange fin production equipment, the fitting groove is used to stably install the lower template on the air transmission seat. The setting of the rubber gasket strip leaves a certain buffer gap between the lower template and the air transmission seat, avoiding the mutual influence caused by the pressure during mold closing, resulting in damage to the lower template and the air transmission seat respectively. And the rubber gasket strip forms a rectangular frame, which can effectively isolate air, enabling the air passage to communicate with the conical air passage. Compressed air passes through the compressed pipeline in the air base, is output through the air holes, and then is respectively introduced into the air transmission pipelines through the connecting pipes, passes through the penetrable conical air passage and the air passage, rises above the lower template, and uses the air pressure thrust to quickly push up the pressed heat exchange fins to separate them from the lower template, thus effectively improving the processing efficiency of the heat exchange fins.

[0022] 6. The improved heat exchange fin production equipment, the rocker arm can rotate on the basis of the pressure pipe, so as to adjust the height position of the connecting plate and the rotating rod. By raising or lowering the position height of the rotating rod, plates of different thicknesses are pushed into the die. The bristles on the outer wall of the rotating rod can increase friction, so that when the rotating rod rotates, it can apply a good thrust to the plate, ensuring the smooth and continuous feeding of the plate. During the rotation of the rotating rod, it applies a thrust to the plate to assist the plate to quickly enter the die, and the fins obtained after production are also quickly and smoothly output from the die by this structure.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0034] Please refer to Figures 1 to 7The present invention provides a technical solution: an improved heat exchange fin production equipment, including a support base 1, a guide mechanism 18, a top plate 22 and a push plate mechanism 30, a hydraulic cylinder 2 is arranged on the left front side and the right rear side of the support base 1, and the output end of the hydraulic cylinder 2 is connected to a hydraulic rod 3, a gas base 4 is fixed to the center of the upper part of the support base 1, and the front side of the gas base 4 is equidistantly penetrated with gas delivery holes 5, a lower mold support base 6 is fixed above the gas base 4, a conveyor belt 7 is arranged inside the upper part of the lower mold support base 6, and the driving shaft of the conveyor belt 7 is connected to a transmission motor 9 at both ends, and the belt surface of the conveyor belt 7 is uniform and staggered A rectangular block 8 is provided, a lower mold base plate 10 is arranged above the conveyor belt 7, and the bottom surface of the lower mold base plate 10 is consistent with the size of the rectangular block 8, an air transfer seat 11 is fixed above the lower mold base plate 10, and a lower mold plate 16 is arranged above the air transfer seat 11. The arrangement of the conveyor belt 7 makes the entire lower mold structure easier to control and use. After the conveyor belt 7 is started, it can correspondingly drive the lower mold base plate 10 and the air transfer seat 11 arranged thereon to move positions, thereby facilitating the replacement of molds, and can quickly adjust the position occupied by the mold, so that the mold can be quickly adjusted in position, so that production and processing can be carried out quickly;

[0035] The upper surface of the gas transmission seat 11 is evenly provided with matching grooves 12, and the inner bottom surface of the matching grooves 12 is rectangular and bonded with rubber pads 13. The inside of the gas transmission seat 11 and the position opposite to the matching grooves 12 are provided with gas transmission pipes 14, and the top of the gas transmission pipes 14 is connected with conical air channels 15. The inside of the lower template 16 is evenly penetrated with air passages 17, and the positions of the air passages 17 and the conical air passages 15 correspond one to one. The gas transmission pipes 14 and the gas delivery holes 5 are connected with connecting pipes 46. The matching grooves 12 are used to stably and well install the lower template 16 on the gas transmission seat 11. The setting of the rubber pads 13 allows the lower template 16 to be left between the gas transmission seat 11. There is a certain buffer gap, which avoids the mutual influence of pressure during mold closing, resulting in damage to the lower mold plate 16 and the air transfer seat 11, and the rubber pad 13 forms a rectangular frame, which can effectively isolate the air, so that the air passage 17 and the conical air passage 15 can be connected by air. The compressed air passes through the compression pipeline in the air base 4, is output through the air delivery hole 5, and is then introduced into the air transfer pipeline 14 by the connecting pipe 46, and passes through the conical air passage 15 and the air passage 17 that can be connected, and rises to the top of the lower mold plate 16. The compressed heat exchange fins can be quickly lifted up to separate from the lower mold plate 16 by using the air pressure thrust, thereby effectively improving the processing efficiency of the heat exchange fins;

[0036] The guiding mechanisms 18 are respectively vertically arranged on the left and right sides above the supporting base 1. The guiding mechanism 18 is composed of a guiding tube 19, a guiding rod 20 and a guiding spring 21. The bottom ends of the guiding tubes 19 are perpendicularly welded to the upper surface of the supporting base 1. The guiding rod 20 vertically penetrates through the inside of the guiding tube 19. A guiding spring 21 is connected between the bottom surface of the guiding rod 20 and the inner bottom surface of the guiding tube 19. The guiding mechanism 18 is used for guiding and buffering the up and down movement of the top plate 22 during the mold opening and closing process. Among them, the telescopic sleeve structure composed of the guiding tube 19 and the guiding rod 20 can be used for guiding the up and down movement of the top plate 22. The addition of the guiding spring 21 enables the guiding tube 19 and the guiding rod 20 to have good telescopic elasticity. With this elasticity, the mold closing pressure can be effectively and well buffered, facilitating the smooth and continuous progress of the mold opening action and avoiding problems such as equipment delay or even jamming;

[0037] The top plate 22 is arranged at the top of the guiding mechanism 18. The top ends of the hydraulic rods 3 are respectively connected to the lower surfaces on the left and right sides of the top plate 22. On the lower side of the top plate 22 and on the left and right sides near the vertical center line of the top plate 22, pneumatic lifting rods 23 are installed. The bottom ends of the pneumatic lifting rods 23 are connected to an upper mold movable seat 24. Buffer insertion channels 25 are arranged on the left and right sides of the upper surface of the upper mold movable seat 24. One ends of buffer springs 26 are fixed to the inner bottoms of the buffer insertion channels 25. The other ends of the buffer springs 26 are respectively fixedly connected to buffer guide rods 27. The buffer guide rods 27 are inserted and fitted in the buffer insertion channels 25. The top ends of the buffer guide rods 27 are welded and fixed to the lower surface of the top plate 22. The buffer part composed of the buffer insertion channels 25, the buffer springs 26 and the buffer guide rods 27 has the same specific structure and function as the guiding mechanism 18. The difference is that the specific object of the guiding mechanism 18 is the top plate 22, while the specific object of the buffer part composed of the buffer insertion channels 25, the buffer springs 26 and the buffer guide rods 27 is the upper mold part. The buffer insertion channels 25 and the buffer guide rods 27 cooperate with each other to ensure that the upper mold movable seat 24 can move up and down stably. The buffer spring 26 enables the up and down movement of the upper mold movable seat 24 to have a certain recovery performance, which can contribute to the smooth completion of the mold opening action after mold closing. The buffer part composed of the buffer insertion channels 25, the buffer springs 26 and the buffer guide rods 27 serves as the main guiding and resetting structure of the upper mold, effectively ensuring the smooth and continuous progress of the mold opening and closing actions. The guiding mechanism 18 serves as the auxiliary guiding and resetting structure of the upper mold, directly and effectively compensating for the guiding deviation or untimely mold parting caused by wear after the production equipment has been used for a long time;

[0038] A upper die base 28 is fixed below the movable seat 24 of the upper die, and a passing plate groove 29 is arranged below the upper die base 28. The push plate mechanism 30 is respectively arranged on the front and rear sides of the upper die base 28. The push plate mechanism 30 is composed of a pressure tube 31, a rocker arm 33, a connecting plate 34, a rotating rod 36, a mounting sleeve 43 and a micro motor 45. The micro motor 45 is fixed on the upper die base 28 through a welding plate, and the micro motors 45 are symmetrical about the vertical center line of the upper die base 28. The middle part of the pressure tube 31 is respectively fixed and hoisted on the front and rear sides of the upper die base 28 through a welding plate. Bearings 32 are sleeved on the outer sides of both ends of the pressure tube 31, and rocker arms 33 are sleeved on the outer sides of the bearings 32. Connecting plates 34 are connected to one side of the ends of the rocker arms 33 close to the vertical center line of the pressure tube 31. Two connecting plates 34 are symmetrically arranged about the vertical center line of the pressure tube 31. A rotating rod 36 is rotatably connected between the connecting plates 34. Shaft rods 35 are fixed at the centers of both end faces of the rotating rod 36. Brush hairs 37 are uniformly arranged in a cross shape on the outer wall surface of the rotating rod 36. The shaft rods 35 respectively penetrate through the centers of the connecting plates 34. Small transmission discs 38 are sleeved on the ends of the shaft rods 35. Transmission belts 39 are sleeved on the outsides of the small transmission discs 38. The other ends of the transmission belts 39 are sleeved with large transmission discs 40. Rotating rods 41 are fixed in the middle parts of the inner walls of the large transmission discs 40. A collar is arranged at the center of the rotating rod 41, and the center of the rotating rod 41 is sleeved on the output shaft end of the micro motor 45. Snap rings 42 protrude from both side faces of the edge of the rotating rod 41. An installation sleeve 43 is arranged on the left side of the rotating rod 41. Slots 44 are arranged on the end face of the installation sleeve 43 close to the rotating rod 41 and the end face of the pressure tube 31 close to the rotating rod 41. The snap rings 42 are respectively slidably fitted in the slots 44;

[0039] By using the bearing 32, not only can the pressure pipe 31 and the rocker arm 33 be well assembled, but also the rocker arm 33 can rotate on the basis of the pressure pipe 31, so as to adjust the height positions of the connecting plate 34 and the rotating rod 36. By raising or lowering the position height of the rotating rod 36, plates of different thicknesses are pushed into the die. The bristles 37 on the outer wall of the rotating rod 36 can increase the friction, so that when the rotating rod 36 rotates, a good thrust can be applied to the plate to ensure the smooth and continuous feeding of the plate. The power of the rotating rod 36 comes from the micro motor 45. After the micro motor 45 is started and rotates by means of the output end, the rotating rod 41 can be driven to rotate. The rotating rod 41 and the large transmission disk 40 are integrally fixed and welded, so the large transmission disk 40 also rotates between the mounting sleeve 43 and the pressure pipe 31 accordingly. And due to the cooperation relationship between the snap ring 42 and the card slot 44, the large transmission disk 40 can rotate relative to the mounting sleeve 43 and the pressure pipe 31. In this way, the large transmission disk 40 can drive the transmission belt 39 to move alone to drive the small transmission disk 38 to rotate. The rotating small transmission disk 38 then drives the rotating rod 36 to rotate through the rotating shaft rod 35. During the rotation of the rotating rod 36, a thrust is applied to the plate to assist the plate to quickly enter the die. The fins obtained after the production are also quickly and smoothly output from the die by this structure;

[0040] In this heat exchange fin production equipment, in addition to two guiding and buffering structures, there are also two pressure die lifting power structures, namely, the hydraulic lifting structure composed of the hydraulic cylinder 2 and the hydraulic rod 3 and the pneumatic lifting structure where the pneumatic lifting rod 23 is located. Among them, the pneumatic lifting rod 23 is the main power part of the upper die part and directly bears the opening and closing die pressure to ensure that the opening and closing die actions can be carried out smoothly and completely. And the hydraulic lifting structure composed of the hydraulic cylinder 2 and the hydraulic rod 3 is the auxiliary power part of the upper die part. Its direct acting object is the top plate 22. By driving the top plate 22 to move up and down, it assists the upper die part to move up and down stably and provides good assistance for the up and down movement of the upper die part, avoiding the problems of inconsistent and untimely opening and closing die actions caused by the aging of the production equipment, and effectively extending the service life and comprehensive use effect of this improved heat exchange fin production equipment.

[0041] In summary, when the improved heat exchange fin production equipment is used, a suitable lower template 16 is assembled onto the air transfer seat 11, a suitable upper template is placed into the upper mold base 28, and the micro motor 45 is started. The micro motor 45 uses the transmission structure composed of the rotating rod 41, the large transmission disk 40, the transmission belt 39 and the small transmission disk 38 to drive the rotating shaft rod 35 and the rotating rod 36 to rotate, and the bristles 37 on the outer wall of the rotating rod 36 are used to push the plate, so that the plate can be quickly and stably transported between the upper and lower molds. The pneumatic lifting rod 23 is started, the upper mold part moves downward as a whole, and the buffer spring 26 is then stretched. In order to ensure sufficient power for opening and closing the mold, the hydraulic cylinder 2 can be started at the same time to drive each hydraulic rod 3 to contract, and the guide spring 21 in the guide mechanism 18 is then contracted. After the die pressing is completed, the buffer spring Under the elastic recovery performance of each of 26 and the guide spring 21, as well as the combined effect of shortening the pneumatic lifting rod 23 and extending the hydraulic rods 3, the upper and lower molds are quickly separated, and the compressed air is quickly input into the compression pipeline in the air base 4, and the compressed air is output through the air delivery hole 5, and then introduced into the air transmission pipeline 14 by the connecting pipe 46, and rises to the top of the lower mold plate 16 through the conical air channel 15 and the air passage 17 that can be connected. By using the air pressure thrust, the pressed heat exchange fins can be quickly lifted up to separate from the lower mold plate 16, and the unprocessed plate is input into the upper and lower molds again through the rotating rod 36 that rotates continuously on the front side, and the processed fin part will also be quickly output from between the upper and lower molds through the rotating rod 36 that rotates continuously on the rear side. Repeating the above steps can complete continuous fin production.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
