Description

[0001] This application is a divisional application of the application filed on September 14, 2024, with application number 202411291719.5 and invention name “A heat exchanger heat dissipation aluminum tube processing device”. Technical Field

[0002] The invention relates to the technical field of aluminum tube processing, in particular to a heat exchanger heat dissipation aluminum tube processing and forming device. Background Art

[0003] The heat dissipation aluminum tube in the heat exchanger is a key component used to transfer heat and dissipate heat effectively. These aluminum tubes are usually designed in long strips with high thermal conductivity and good corrosion resistance to ensure the efficient operation of the heat exchanger.

[0004] The patent with patent announcement number CN215146656U relates to an adjustable aluminum tube cutting device, including a U-shaped base, a grinding mechanism is arranged on the inner side of the U-shaped base, a horizontal plate is fixed at the upper end of the U-shaped base, through holes are symmetrically opened on the horizontal plate, an L-shaped frame is fixed at the upper end of the horizontal plate, a horizontal plate is fixed at the bottom end of the L-shaped frame, grooves are symmetrically opened at both ends of the horizontal plate, a clamping mechanism is arranged on the inner side of the groove, a cutting mechanism is arranged at the lower end of the horizontal plate, and an aluminum tube is arranged below the cutting mechanism. The patent is provided with a clamping mechanism that can clamp and limit the aluminum tube, and the cutting mechanism is used to cut the aluminum tube. The patent can adjust the position of the two aluminum tubes formed by cutting so that the incision is facing downward, and the incision is polished by the grinding mechanism. There is no need to move the aluminum tube to the next process for polishing, which improves safety and facilitates operation.

[0005] The above patent has the function of adjusting the positions of the two aluminum tubes. A clamping mechanism is set on the inner side of the groove to ensure that the clamping mechanism can stably clamp the aluminum tube, ensuring that the aluminum tube will not deviate during the cutting process, thereby affecting the cutting accuracy. At the same time, the incision is polished by a polishing mechanism, and there is no need to move the aluminum tube to the next process for polishing, which effectively improves the convenience of operation. However, when clamping the aluminum tube, the surface of the circular aluminum tube is a smooth circle, and compared with other shapes, the clamping area is smaller, so the clamping force is not as stable as for pipes of other shapes, resulting in the aluminum tube being prone to slight movement or rotation during the cutting process, thereby affecting the processing accuracy and consistency.

[0015] The present invention provides a heat exchanger heat dissipation aluminum tube processing and forming device. It has the following beneficial effects:

[0016] (1) In the heat exchanger heat dissipation aluminum tube processing and forming device, the sleeve transmits the reaction force to the clamping plate, and the clamping plate applies a clamping force to the aluminum tube under the action of the reaction force. The No. 1 spring is squeezed to apply a reaction force to the sleeve, ensuring that the clamping plate applies sufficient clamping force to both ends of the aluminum tube, thereby improving the clamping effect of the aluminum tube. The No. 1 spring applies a thrust to the rubber plate, and the arc surface No. 2 applies a supporting force to the inner wall of the aluminum tube under the action of the thrust. The rubber plate is stretched to contact the inner wall of the aluminum tube and applies a supporting force to the inner wall of the aluminum tube, effectively preventing the aluminum tube from being deformed or vibrated during cutting, thereby improving the accuracy of the cutting process.

[0017] (2) In the heat exchanger heat dissipation aluminum tube processing and forming device, the cylindrical rod is in contact with the inner wall of the circular hole, so that the cylindrical rod imposes a limit on the cover plate. The cylindrical rod automatically passes through the circular hole to impose a limit on the cover plate when clamping, ensuring that the cover plate cannot be actively opened during the cutting process, effectively improving the accuracy of the cover plate use, and the limit block releases the limit, allowing the deformed No. 2 spring to recover normally. By imposing restrictions on the recovery of the No. 2 spring, the staff can quickly release the limit on the limit block after standardized operation and remove the aluminum tube, which helps to improve the standardization of the operation.

[0018] (3) In the heat exchanger heat dissipation aluminum tube processing and forming device, the cutting knife contacts the grinding plate during the process of cutting the aluminum tube, so that the cutting knife is grinded by the grinding plate during the rotation process. The grinding plate grinds the cutting knife in real time during the cutting process, effectively preventing the blade from quickly losing its sharpness due to friction during the cutting process, thereby maintaining the stability of the cutting process. The pull rod is limited and cannot move, resulting in the connection plate being unable to contact the circumferential surface of the pull rod. By pulling the pull rod to move to the specified position and then limiting it, the staff can actively choose to use the grinding plate for grinding. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] 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 invention. 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.

[0029] See also Figure 1-Figure 8An embodiment of the present invention is: a heat exchanger heat dissipation aluminum tube processing and forming device, including a processing machine 1, a linear drive mechanism 2 is fixedly installed on the side wall of the processing machine 1, a support frame 3 is fixedly installed on the output end of the linear drive mechanism 2, a cutting mechanism 4 is arranged on the support frame 3, the cutting mechanism 4 includes a driving device and a cutting knife, the driving device is fixedly penetrated through the top of the support frame 3, the cutting knife is fixedly installed at the output end of the driving device, a placement frame 5 is fixedly installed on the top of the processing machine 1, a cover plate 6 is rotatably installed on the top of the placement frame 5, a round hole is opened on the side wall of the cover plate 6, and a clamping device is also included; wherein the clamping device includes an electric push rod 7, a hollow rod 8, a sleeve 9, a No. 1 spring 10, a clamping plate 11, a contact plate 12, a butt plate 13, a rubber plate 14 and a No. 1 spring 15, the electric push rod 7 is fixedly installed on the top of the processing machine tool 1, the hollow rod 8 is fixedly installed on the output end of the electric push rod 7, the sleeve 9 slides and penetrates the inner and outer walls of the hollow rod 8, the No. 1 spring 10 is arranged between the sleeve 9 and the hollow rod 8, the clamping plate 11 is fixedly installed on the circumferential surface of the sleeve 9, the contact plate 12 is fixedly installed on the side of the clamping plate 11 close to the electric push rod 7, the push plate 13 slides and penetrates the inner and outer walls of the sleeve 9, the rubber plate 14 slides and penetrates the side of the push plate 13 away from the sleeve 9, the No. 1 spring sheet 15 is arranged between the rubber plate 14 and the push plate 13, the circumferential surface of the hollow rod 8 is provided with a slide groove, the sleeve 9 contacts with the inner wall of the slide groove, and the No. 1 spring 10 is squeezed to apply a reaction force to the sleeve 9, ensuring that the clamping plate 11 stably applies sufficient clamping force to both ends of the aluminum tube, thereby effectively improving the stability during processing.

[0030] A spherical surface is provided at one end of the hollow rod 8 close to the sleeve 9, and an anti-skid groove is provided on the side of the clamping plate 11 away from the contact plate 12. By providing the anti-skid groove on the clamping plate 11, when the clamping plate 11 contacts the two ends of the aluminum tube, the anti-skid groove increases the friction force, so that the clamping plate 11 can accurately clamp the two ends of the aluminum tube.

[0031] A sloped surface 1 is provided on one side of the support plate 13 away from the rubber plate 14, and an arcuate surface 2 is provided on one side of the rubber plate 14 away from the support plate 13. The rubber plate 14 is stretched inside the aluminum tube to effectively prevent the aluminum tube from being deformed or vibrated during cutting, ensuring that the aluminum tube will not rotate slightly during the cutting process to affect the cutting accuracy.

[0032] When the present embodiment is working, the cover plate 6 is opened, the aluminum tube is placed on the top of the placement rack 5, and the cover plate 6 is closed. The cover plate 6 contacts the circumferential surface of the aluminum tube during the closing process, and the electric push rod 7 is started. The output end of the electric push rod 7 moves to drive the hollow rod 8 to move toward the placement rack 5. The hollow rod 8 moves to drive the sleeve 9 to move toward the placement rack 5. The sleeve 9 enters the interior of the aluminum tube during the movement. At the same time, the sleeve 9 moves to drive the clamping plate 11 to move toward the placement rack 5. The clamping plate 11 moves to drive the contact plate 12 to move toward the placement rack 5. The anti-skid groove of the clamping plate 11 contacts the aluminum tube during the movement. One end is in contact, the aluminum tube blocks the movement of the clamping plate 11, so that the clamping plate 11 and the sleeve 9 stop moving, and the hollow rod 8 continues to move to squeeze the No. 1 spring 10. The No. 1 spring 10 is squeezed and deformed. The deformed No. 1 spring 10 exerts a reaction force on the sleeve 9 under the action of its own elasticity. The sleeve 9 transmits the reaction force to the clamping plate 11. The clamping plate 11 exerts a clamping force on the aluminum tube under the action of the reaction force, so that the clamping plate 11 stably clamps the aluminum tube. The No. 1 spring 10 is squeezed and exerts a reaction force on the sleeve 9, ensuring that the clamping plate 11 exerts a stable clamping force on both ends of the aluminum tube. The holding force effectively improves the stability during processing. The spherical surface 1 of the hollow rod 8 contacts the inclined surface 1 during movement. The movement of the spherical surface 1 applies a thrust to the inclined surface 1. The push plate 13 is affected by the thrust and moves in a direction away from the sleeve 9. The movement of the push plate 13 drives the rubber sheet 14 to move in a direction away from the sleeve 9. The arc surface 2 of the rubber sheet 14 contacts the inner wall of the aluminum tube during the movement, so that the rubber sheet 14 is blocked by the aluminum tube and stops moving. The push plate 13 continues to move to squeeze the No. 1 spring sheet 15. The No. 1 spring sheet 15 is squeezed and deformed. The No. 1 spring sheet 15 exerts pressure on the rubber sheet 14 during the deformation process. The plate 14 applies a thrust, and the arc surface 2 applies a supporting force to the inner wall of the aluminum tube under the action of the thrust, starting the cutting mechanism 4, and the driving device of the cutting mechanism 4 drives the cutting knife to rotate, starting the linear driving mechanism 2, and the output end of the linear driving mechanism 2 moves to drive the support frame 3 to move toward the placement frame 5. The movement of the support frame 3 drives the cutting mechanism 4 to move toward the placement frame 5. The cutting knife contacts the aluminum tube during the movement, so that the cutting knife cuts the aluminum tube. The rubber plate 14 is opened inside the aluminum tube to effectively prevent the aluminum tube from being deformed or vibrated during cutting, thereby improving the cutting accuracy.

[0033] See also Figure 1-Figure 8On the basis of the above embodiment, another embodiment of the present invention further includes a locking device and a grinding device; the locking device includes a carrying plate 161, a telescopic plate 162, a second spring 163, a limit block 164, a second spring 165, a push plate 166, a connecting plate 167 and a cylindrical rod 168, the carrying plate 161 is fixedly penetrated through the top of the placement rack 5, the telescopic plate 162 slides through the side of the carrying plate 161 close to the sleeve 9, the second spring 163 is arranged between the telescopic plate 162 and the carrying plate 161, and the limit block 164 slides through The telescopic plate 162 is on a side away from the placement rack 5, the No. 2 spring piece 165 is set between the limit block 164 and the telescopic plate 162, the push plate 166 slides through the inner and outer walls of the mounting plate 161, the connecting plate 167 is fixedly installed on the side of the telescopic plate 162 away from the mounting plate 161, and the cylindrical rod 168 is fixedly installed on the side of the connecting plate 167 close to the circular hole. By imposing restrictions on the recovery of the No. 2 spring 163, the staff can remove the aluminum tube only after standardized operation, avoiding the situation of the aluminum tube getting out of control during the cutting process, which helps to improve the standardization of the operation.

[0034] The limit block 164 has an arc surface three on one side away from the telescopic plate 162, and the arc surface three contacts the inner wall of the mounting plate 161. By providing the arc surface three on the limit block 164, the friction between the limit block 164 and the mounting plate 161 when moving is effectively reduced, thereby extending the service life of the limit block 164.

[0035] A corrugation is provided on one side of the push plate 166 away from the mounting plate 161. The size of the cylindrical rod 168 is adapted to the circular hole. The cylindrical rod 168 passes through the circular hole to limit the cover plate 6, ensuring that the cover plate 6 cannot be actively opened during the cutting process, thereby effectively improving the safety of the aluminum tube during the cutting process.

[0036] The grinding device includes a loading frame 171, a rectangular plate 172, a Z-shaped sheet 173, a sharpening plate 174, a pull rod 175, a No. 3 spring 176 and a card plate 177. The loading frame 171 is fixedly installed on the top of the placement frame 5, the rectangular plate 172 is slidably installed on the bottom of the loading frame 171, the Z-shaped sheet 173 is arranged between the rectangular plate 172 and the loading frame 171, the sharpening plate 174 is fixedly installed on the side of the rectangular plate 172 away from the sleeve 9, the pull rod 175 slides through the side of the rectangular plate 172 close to the connecting plate 167, the No. 3 spring 176 is arranged between the pull rod 175 and the rectangular plate 172, the card plate 177 slides through the top of the rectangular plate 172, and the Z-shaped sheet 173 itself is elastic. The cutting knife is polished in real time by the sharpening plate 174 during the cutting process, which effectively prevents the blade from quickly losing its sharpness due to friction during the cutting process.

[0037] A card slot is provided on the circumferential surface of the pull rod 175, and an arc surface four is provided on the bottom of the card plate 177. The arc surface four contacts the circumferential surface of the pull rod 175. By pulling the pull rod 175 to move to the specified position and then limiting it, the staff can actively choose to use the sharpening plate 174, thereby improving the applicability of the sharpening plate 174.

[0038] When the present embodiment is working, the contact plate 12 moves and contacts with the connecting plate 167. The movement of the contact plate 12 applies a thrust to the connecting plate 167. The connecting plate 167 is affected by the thrust and moves toward the mounting plate 161. The movement of the connecting plate 167 drives the telescopic plate 162 to move toward the mounting plate 161. The telescopic plate 162 squeezes the No. 2 spring 163 during the movement. The No. 2 spring 163 is squeezed and deformed. At the same time, the movement of the connecting plate 167 drives the cylindrical rod 168 to move toward the mounting plate 161. The cylindrical rod 168 passes through the circular hole during the movement. The inner wall of the cylindrical rod 168 contacts the inner wall of the circular hole, so that the cylindrical rod 168 limits the cover plate 6, and the staff cannot open it. After the cutting of the cover plate 6 is completed, the contact plate 12 is reset and the side in contact with the connecting plate 167 is separated, so that the thrust exerted by the contact plate 12 on the connecting plate 167 is gradually reduced, and the deformed No. 2 spring 163 is restored under the action of its own elasticity, and the No. 2 spring 163 is restored to drive the telescopic plate 162 to move away from the mounting plate 161, and the movement of the telescopic plate 162 drives the connecting plate 167 to move away from the mounting plate 161, and the movement of the connecting plate 167 drives the cylindrical rod 168 to move away from the cover plate 6. During the movement, the cylindrical rod 168 is separated from the side in contact with the circular hole, so that the limit exerted by the cylindrical rod 168 on the cover plate 6 is released, and the cover is pressed by the cylindrical rod 168 passing through the circular hole. The plate 6 applies a limit to ensure that the cover plate 6 cannot be opened during the cutting process, thereby improving the safety of cutting. The movement of the telescopic plate 162 drives the limit block 164 to move in the direction of the push plate 166. The arc surface three of the limit block 164 is separated from the side in contact with the inner wall of the mounting plate 161 during the movement, so that the deformed second spring piece 165 is restored under the action of its own elasticity. The second spring piece 165 restores and applies a thrust to the limit block 164. The limit block 164 is affected by the thrust and moves in the direction away from the telescopic plate 162. The arc surface three contacts the side of the push plate 166 close to the telescopic plate 162 during the movement. The movement of the limit block 164 drives the push plate 166 to move in the direction away from the telescopic plate 162. The limit block 164 is limited by the carrying plate 161 during the movement, so that the recovery of the squeezed No. 2 spring 163 is restricted. When the staff wants to take out the cut aluminum tube, they first reset the sleeve 9, and then press the push plate 166 to move toward the carrying plate 161. The movement of the push plate 166 drives the limit block 164 to move toward the telescopic plate 162. The limit block 164 squeezes the No. 2 spring 165 during the movement. At the same time, the limit block 164 releases the limit when moving, so that the deformed No. 2 spring 163 can recover normally. By restricting the recovery of the No. 2 spring 163, the staff can remove the aluminum tube only after standard operation, which helps to improve the standardization of the operation.

[0039] When the connecting plate 167 moves, it contacts the circumferential surface of the pull rod 175. The movement of the connecting plate 167 applies a thrust to the pull rod 175. The pull rod 175 is affected by the thrust and moves toward the grinding plate 174. The movement of the pull rod 175 drives the rectangular plate 172 to move toward the grinding plate 174. The rectangular plate 172 squeezes the Z-shaped piece 173 during the movement. The Z-shaped piece 173 is squeezed and deformed. At the same time, the movement of the rectangular plate 172 drives the grinding plate 174 to move away from the loading frame 171. The grinding plate 174 stops moving after moving to a predetermined position, so that the cutting knife contacts the grinding plate 174 during the process of cutting the aluminum tube, so that the cutting knife is polished by the grinding plate 174 during the rotation process. The grinding plate 174 grinds the cutting knife in real time during the cutting process, which effectively prevents the blade from being worn during the cutting process. The blade quickly loses its sharpness due to friction. When the staff does not need to sharpen it, they pull the rod 175 to move away from the connecting plate 167. The rod 175 stretches the No. 3 spring 176 during the movement, and the No. 3 spring 176 is deformed due to the stretching. At the same time, the rod 175 is separated from the side in contact with the arc surface four during the movement, so that the supporting force exerted by the rod 175 on the arc surface four gradually decreases, and the card plate 177 moves downward under the action of gravity. The card plate 177 contacts the inner wall of the card slot during the movement, so that the card plate 177 limits the rod 175. The rod 175 is limited and cannot move, resulting in the connecting plate 167 being unable to contact the circumferential surface of the rod 175 during the movement. By pulling the rod 175 to the specified position and then limiting it, the staff can actively choose to use the sharpening plate 174.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
