Description

Technical Field

[0001] The present application relates to the technical field of aluminum profile forming, and in particular to a cooling device for automobile aluminum profile forming. Background Art

[0002] Aluminum profiles are often used in automobile vehicle structures, engine brackets, radiator structures, etc. due to their obvious weight reduction effects, good corrosion resistance, and good thermal conductivity. These components are usually made of stamped aluminum profiles and extruded aluminum profiles.

[0003] A large amount of heat will be generated during the stamping and extrusion of aluminum profiles. In order to reduce the influence of heat on the deformation and performance of aluminum plates, it is often necessary to cool the stamped or extruded aluminum parts. For example, the patent application with publication number CN111872147A provides a rapid cooling device for aluminum profile processing. The device includes a material transport rack, a liquid collecting box, a liquid storage tank, a filter cotton layer and a cooling circulation system. After the coolant is collected in the liquid collecting box at the bottom of the material transport rack, impurities are removed by the filter cotton layer and then stored in the liquid storage tank. The coolant in the liquid storage tank is circulated to the spray pipe by controlling the water pump. During the process, the cooling fan heats up and cools the coolant flowing through to ensure the temperature of the coolant is stable, thereby evenly cooling the aluminum profile. Although this device provides a certain cooling effect, it still faces significant problems in practical applications. For example, the cooling effect of the coolant on the aluminum profile on both sides of the spray pipe is inconsistent, resulting in a large temperature difference on both sides of the aluminum profile, resulting in uneven stress distribution inside the aluminum profile, affecting its cooling and forming effect and final straightness.

[0004] The continuous temperature unevenness of such traditional cooling equipment may cause uneven stress in the cooling process of the aluminum profile, which in turn affects the cooling and forming effect and the flatness of the final product. In order to improve this defect, the existing technology needs to further optimize the cooling process to ensure that the temperature of each part of the aluminum profile is consistent, avoiding deformation and performance degradation caused by inconsistent temperature.

[0005] Therefore, the field is in urgent need of a new technology that can effectively improve the cooling uniformity of aluminum profiles, so as to solve the temperature unevenness problem existing in the prior art, improve the cooling and forming effect of aluminum profiles, ensure their flatness, and thus improve the quality and performance of the final product.

DETAILED DESCRIPTION

[0042] The following is combined with Figures 1 to 11 This application is described in further detail.

[0043] The embodiment of the present application discloses a cooling device for automobile aluminum profile forming, which quickly completes the spraying and cooling process under the condition of limited displacement of the automobile aluminum profile, effectively reducing the temperature difference before and after the automobile aluminum profile is sprayed, thereby reducing the possibility of flatness of the automobile aluminum profile due to uneven temperature.

[0044] Example 1: Reference Figure 1 and Figure 2 A cooling device for automobile aluminum profile forming includes a horizontal frame 1, on which are installed a limiting mechanism 2 for fixing and supporting the automobile aluminum profile 100 and driving the automobile aluminum profile 100 to move back and forth, and a cooling mechanism 3 for cooling the automobile aluminum profile 100.

[0045] The limiting mechanism 2 includes: a reciprocating frame 21, which is slidably arranged on the horizontal frame 1, and a support frame 1 22 and a support frame 23 are symmetrically arranged along the length direction of the reciprocating frame 21, and the support frame 1 22 is detachably installed on the reciprocating frame 21.

[0046] The opposite surfaces of the support frame 1 22 and the support frame 2 23 are both installed with supporting shafts 24 , and a supporting shaft 25 for supporting and limiting the automobile aluminum profile 100 is commonly arranged between the supporting shafts 24 .

[0047] The reciprocating frame 21 cooperates with the support frame 1 22 and the support frame 2 23 through the supporting shaft 24, and can drive the automobile aluminum profile 100 to reciprocate, so that the surface of the automobile aluminum profile 100 is sprayed with water mist in a relatively short displacement, so that the automobile aluminum profile 100 can quickly complete the spraying and cooling process under the condition of limited displacement, effectively reducing the temperature difference of the automobile aluminum profile 100 before and after spraying, thereby reducing the possibility of affecting the straightness of the automobile aluminum profile 100 due to uneven temperature.

[0048] Reference Figure 2 and Figure 3 The cooling mechanism 3 includes: a fixed frame 31, a plurality of sets of which are evenly arranged along the length direction of the horizontal frame 1, and each set of the fixed frames 31 is symmetrically installed on the horizontal frame 1 along the width direction of the horizontal frame 1, and an annular tube 32 is commonly installed on each set of the fixed frames 31.

[0049] The nozzles 33 are arranged inside the annular tube 32 and are evenly arranged in a plurality along the circumference of the annular tube 32 , and are connected to the annular tube 32 through-holes.

[0050] There are multiple spray pipes 34 and they are evenly distributed along the circumference of the support shaft 25. One side of the spray pipe 34 close to the support shaft 25 is symmetrically provided with support protrusions along its length direction, and the spray pipe 34 is installed on the support shaft 25 through the support protrusions.

[0051] Reference Figure 4 A supporting disc 241 is installed on the opposite surface of the supporting shaft 24, and a plurality of supporting claws 242 for supporting the automobile aluminum profile 100 are evenly arranged on the opposite surface of the supporting disc 241 in a circumferential direction.

[0052] The support frame 1 22 is symmetrically provided with fixing protrusions along the width direction of the horizontal frame 1, and a limiting rod is slidably provided on the fixing protrusion, and the limiting rod can be clamped on the horizontal frame 1, and then the limiting rod can fix and limit the support frame 1 22 through the cooperation between the fixing protrusion and the horizontal frame 1.

[0053] The automobile aluminum profile 100 designed by the present invention is a through cylindrical structure. The circumferential surface of the automobile aluminum profile 100 is evenly provided with a plurality of fins along its circumferential direction. In specific operation, before cooling and cooling treatment, the limit rod is taken out and the support frame 22 is removed, which plays a role of giving way during the transportation process of the automobile aluminum profile 100 to avoid collision between the automobile aluminum profile 100 and the support frame 22. After the automobile aluminum profile 100 is formed, the automobile aluminum profile 100 is transported by the existing transport equipment (transport robot, etc.) through the support frame 22. The shaft 25 is placed on the supporting shaft 24 corresponding to the support frame 23, so that the supporting disc 241 and the supporting claw 242 cooperate with each other to support the automotive aluminum profile 100. At this time, the automotive aluminum profile 100 is located inside the annular tube 32 and is coaxial with each annular tube 32. At this time, the limit rod is reset. At this time, the support frame 1 22 is fixedly connected to the horizontal frame 1, and the support frame 1 22 and the support frame 2 23 cooperate with each other to support and limit the automotive aluminum profile 100 through the supporting shaft 24.

[0054] When the support and limit of the automobile aluminum profile 100 is completed, water is pumped into the annular tube 32, wherein a transition pipe is installed between the annular tubes 32, and the transition pipe is connected to the water outlet of an existing water pump (not shown in the figure). The existing water pump pumps water into the annular tube 32 through the transition pipe, and then the water is sprayed out from the nozzle 33 after passing through the annular tube 32. The sprayed water mist can cool the outer surface of the automobile aluminum profile 100 and its surface fins.

[0055] Reference Figure 5 During the water mist spraying process, the reciprocating frame 21 cooperates with the support frame 1 22 and the support frame 2 23 through the supporting shaft 24, and can drive the automobile aluminum profile 100 to reciprocate. The reciprocating part 11 provided on the horizontal frame 1 of the present invention can drive the reciprocating frame 21 to reciprocate. Specifically, the reciprocating part 11 includes: a telescopic spring 111, which is installed between the reciprocating frame 21 and the horizontal frame 1 for resetting the reciprocating frame 21.

[0056] The vertical frame 112 is mounted on the horizontal frame 1 and has a winding shaft 113 rotatably mounted therethrough.

[0057] The traction rope 114 is installed on the second support frame 23 , and one end of the traction rope 114 away from the second support frame 23 is wound around the winding shaft 113 .

[0058] The reversing shaft 115 is mounted on the horizontal frame 1 through a bearing and is used to reverse the traction rope 114.

[0059] During specific operation, the winding shaft 113 is driven by the existing driving motor to rotate a certain number of circles. During the rotation of the winding shaft 113, the traction rope 114 is wound. When the traction rope 114 is wound and rolled, the reciprocating frame 21 is synchronously driven to move synchronously. The telescopic spring 111 is compressed due to the movement of the reciprocating frame 21 to one side of the reversing shaft 115. At this time, the reciprocating frame 21 cooperates with the support frame 1 22 and the support frame 23 through the supporting shaft 24 to synchronously drive the automobile aluminum profile 100 to move. After the winding shaft 113 rotates a certain number of circles, the winding shaft 113 stops rotating. At this time, the output shaft of the driving motor drives the winding shaft 113 to reverse, and then the telescopic spring 111 is no longer constrained and resets. The reciprocating frame 21 cooperates with the support frame 1 22 and the support frame 23 through the supporting shaft 24 to synchronously drive the automobile aluminum profile 100 away from the reversing shaft 115. Repeating the above actions can make the automobile aluminum profile 100 reciprocate along the length direction of the horizontal frame 1.

[0060] Therefore, through the above steps, the surface of the automobile aluminum profile 100 is sprayed with water mist in a relatively short displacement, so that the automobile aluminum profile 100 can quickly complete the spraying and cooling process under the condition of limited displacement.

[0061] In addition, the sprayed water mist can gather between the fins, thereby cooling the surface of the automotive aluminum profile 100 and also removing part of the heat from the surface of the automotive aluminum profile 100 .

[0062] Reference Figure 5 When the spray head 33 sprays water mist, the support shaft 25 rotates synchronously to drive the spray pipe 34 to cool the inner wall of the automobile aluminum profile 100. Specifically, a linkage frame 211 is installed at one end of the reciprocating frame 21 close to the winding shaft 113, and a sleeve 212 is rotatably installed on the linkage frame 211 through a bearing, and the sleeve 212 is limitedly slidably sleeved on the winding shaft 113, and the sleeve 212 is connected to the support shaft 25 through a belt drive.

[0063] During specific operation, when the winding shaft 113 rotates, the sleeve 212 is driven to rotate together, and the sleeve 212 further drives the support shaft 25 to rotate through a belt drive. When the support shaft 25 rotates, the spray pipe 34 is driven to reciprocate inside the automobile aluminum profile 100 through the supporting protrusion. At this time, water is pumped into the spray pipe 34 by the existing water pump, and the water is sprayed onto the inner wall of the automobile aluminum profile 100 through the spray pipe 34, thereby achieving cooling of the automobile aluminum profile 100.

[0064] The spray head 33 and the spray pipe 34 cooperate with each other to cool the inner and outer surfaces of the automobile aluminum profile 100 at the same time, further reducing the temperature difference before and after the automobile aluminum profile 100 is sprayed. The linkage frame 211 maintains the same moving speed as the support shaft 25 during the driving process of the reciprocating frame 21, ensuring the smooth belt transmission between the sleeve 212 and the support shaft 25. In addition, a limited position protrusion is provided on the winding shaft 113, which can limit the relative rotation of the sleeve 212, ensuring that the sleeve 212 slides along the length direction of the winding shaft 113 and maintains stable operation.

[0065] Continue to refer to Figure 5 In order to make the water flow accumulated on the wing cool the automobile aluminum profile 100 more evenly, the supporting shaft 24 designed in the present invention can drive the automobile aluminum profile 100 to rotate. Specifically, a linkage shaft 231 is rotatably installed on the support frame 23 through a bearing, and the linkage shaft 231 is connected to the support shaft 25 through a gear transmission method, and the linkage shaft 231 is connected to the supporting shaft 24 set on the support frame 23 through a belt transmission method.

[0066] During specific operation, the support shaft 25 drives the linkage shaft 231 to rotate through the gear transmission method during rotation, and the linkage shaft 231 drives the supporting shaft 24 to rotate through the belt transmission method during rotation, and then the supporting shaft 24 rotates through the cooperation between the supporting disc 241 and the supporting claw 242 to drive the automobile aluminum profile 100 and the support shaft 25 to rotate in the opposite direction. During the rotation of the automobile aluminum profile 100, the automobile aluminum profile 100 can be cooled by the accumulated water flow between adjacent fins, thereby avoiding the possibility of uneven cooling of the outer surface of the automobile aluminum profile 100 due to the inability of the fins at the bottom to store water, thereby reducing the possibility of affecting the straightness of the automobile aluminum profile 100 due to uneven cooling of the outer surface of the automobile aluminum profile 100.

[0067] As the temperature of the automotive aluminum profile 100 decreases, after a period of time, the water mist sprayed inside it accumulates in small amounts as the temperature decreases. During the rotation of the automotive aluminum profile 100, the water flow on the inner wall of the automotive aluminum profile 100 can also be driven to converge and flow along its inner wall, and the flowing water can also have a cooling effect.

[0068] In addition, during the rotation of the automotive aluminum profile 100, the fins on its surface can also fan the air flow around it, and the flowing air can also take away part of the heat on the surface of the automotive aluminum profile 100, so that the cooling effect of the surface of the automotive aluminum profile 100 is better.

[0069] Reference Figure 6 and Figure 7A circular groove extending along the length direction is provided inside the support shaft 25, and a plurality of support claws 251 are evenly provided on the circumferential surface of the support shaft 25 and located between adjacent spray pipes 34 along the length direction of the support shaft 25. An automatically reset support claw 252 is slidably provided on the support claw 251 along the length direction, and one end of the support claw 252 located inside the support claw 251 is provided through the circular groove, and a ball 253 is installed on the end of the support claw 252 away from the circular groove, and an adjustment portion 254 for adjusting the support claw 252 is provided inside the circular groove.

[0070] The adjusting part 254 includes a sliding rod 255 which is slidably arranged inside the circular groove and automatically resets. The sliding rod 255 is provided with an inclined groove 256 which matches the supporting claw 252 , and one end of the supporting claw 252 located inside the circular groove abuts against the inside of the inclined groove 256 .

[0071] The resistance rod 257 is installed on the supporting disc 241 close to the supporting frame 1 22 and is used to push the sliding rod 255.

[0072] The supporting claw 252 and the supporting claw 251 are provided with an elastic member for resetting the supporting claw 252. The sliding rod 255 and the inner part of the circular groove are provided with an elastic member for resetting the sliding rod 255. Since the elastic member is common knowledge, it is not described in detail and is not shown in the figure. When the supporting frame 22 is reset, the supporting disc 241 on the supporting frame drives the abutment rod 257 to be inserted into the inner part of the circular groove. The abutment rod 257 pushes the sliding rod 255 to move in the inner part of the circular groove during the movement of the sliding rod. During the movement of 255, the supporting claw 252 is driven by the inclined groove 256 to move toward the side of the automobile aluminum profile 100, and is tightly attached to the inner wall of the automobile aluminum profile 100. Then, the supporting shaft 25 can cooperate with the supporting claw 251 and the supporting claw 252 to perform internal support treatment on the automobile aluminum profile 100, thereby ensuring that the automobile aluminum profile 100 does not shake during the rotation process, thereby reducing the possibility of the automobile aluminum profile 100 shaking and causing the automobile aluminum profile 100 to be deflected, and reducing the possibility of the automobile aluminum profile 100 The straightness of the automobile aluminum profile 100 decreases due to shaking.

[0073] The ball 253 can reduce the friction between the supporting claw 252 and the automotive aluminum profile 100 during the rotation of the automotive aluminum profile 100, avoiding the possibility of the supporting claw 252 breaking due to rigid friction between the inner wall of the automotive aluminum profile 100 and the supporting claw 252, and at the same time protecting the inner wall of the automotive aluminum profile 100.

[0074] Reference Figure 7One end of the support shaft 25 close to the support frame 23 is slidably provided with a plurality of circumferentially evenly distributed moving rods 258, and the moving rods 258 are installed on the sliding rods 255, and the end of the moving rods 258 away from the support shaft 25 is jointly installed with an annular rod 259 that cooperates with the corresponding side supporting claw 242.

[0075] The supporting claws 242 corresponding to the support frame 23 are slidably set on the corresponding supporting disc 241 and can be automatically reset. An elastic member (not shown in the prior art) is installed between the supporting claws 242 corresponding to the support frame 23 and the corresponding supporting disc 241 for resetting the supporting claws 242. In the starting position, the diameter of the circle formed by the line connecting the adjacent supporting claws 242 corresponding to the support frame 23 is smaller than the inner wall diameter of the automobile aluminum profile 100, and the diameter of the circle formed by the line connecting the adjacent supporting claws 242 corresponding to the support frame 1 22 of the automobile aluminum profile 100 is slightly smaller than the inner wall diameter of the automobile aluminum profile 100, so that the automobile aluminum profile 100 can smoothly pass through the supporting claws 242 during the placement and limiting process. A guiding inclined surface is arranged on the side of the annular rod 259 close to the supporting claw 242 on the corresponding side, and a linkage protrusion matching the guiding inclined surface is arranged on the corresponding supporting claw 242.

[0076] During specific operation, the sliding rod 255 drives the moving rod 258 to move, and the moving rod 258 drives the annular rod 259 to move. During the movement of the annular rod 259, the inclined surface of the annular rod 259 cooperates with the linkage protrusion to drive the corresponding supporting claw 242 to open. At this time, the supporting claw 242 can play an internal support and limiting role for the automobile aluminum profile 100, and at the same time ensure that the supporting shaft 24 on the support frame 23 can drive the automobile aluminum profile 100 to rotate through the supporting disc 241 and the corresponding supporting claw 242 during rotation, thereby reducing the possibility of relative sliding between the inner wall of the automobile aluminum profile 100 and the corresponding supporting claw 242.

[0077] Reference Figure 5 as well as Figure 8 A plurality of through-connecting grooves 250 are evenly arranged in the circumferential direction inside the support shaft 25 , and a plurality of air inlet grooves 2510 that are connected to the through-connecting grooves 250 are evenly arranged on the circumferential surface of the support shaft 25 .

[0078] During specific operation, the through-connecting groove 250 is connected to the air inlet of an external air pump (not shown in the figure), and the external air pump is started to discharge the gas inside the through-connecting groove 250 to the outside. Through the pressure difference between the inside and outside of the through-connecting groove 250, the water vapor generated by the spraying and gasification inside the automobile aluminum profile 100 can be pressed into the through-connecting groove 250 through the air inlet groove 2510, and then the water vapor generated by the spraying and gasification can be discharged to the outside, thereby taking the heat inside the automobile aluminum profile 100 out, further improving the cooling effect of the automobile aluminum profile 100.

[0079] Reference Figure 3 and Figure 4 The support shaft 25 has blades 2511 symmetrically mounted in the middle along its length direction, and the supporting disc 241 has a plurality of ventilation grooves 2512 evenly arranged circumferentially.

[0080] The fan blades 2511 are installed in opposite directions and are provided in two groups. Each group of fan blades 2511 is evenly distributed along the circumference of the support shaft 25. During specific operation, when the support shaft 25 rotates forward, one group of fan blades 2511 can rotate synchronously to blow the air flow inside the automobile aluminum profile 100, and then the flowing air can discharge part of the heat inside the automobile aluminum profile 100 through the ventilation groove 2512. When the support shaft 25 rotates reversely, the remaining group of fan blades 2511 can rotate synchronously to blow the air flow inside the automobile aluminum profile 100 and bring out the heat inside the automobile aluminum profile 100, thereby further improving the cooling effect of the automobile aluminum profile 100.

[0081] When the automotive aluminum profile 100 is cooled down, it is removed, and the cooling down work of the automotive aluminum profile 100 is now finished.

[0082] Example 2: Reference Figures 9 and 10 On the basis of the first embodiment, in order to further ensure the cooling effect of the automobile aluminum profile 100 and avoid the possibility of continuous bending of the automobile aluminum profile 100, the straightening part 4 provided by the present invention can straighten the automobile aluminum profile 100 during the cooling process. Specifically, the straightening part 4 includes a reciprocating plate 41 arranged on the reciprocating frame 21, and the reciprocating plate 41 is provided with a vertical rod 42 located between adjacent annular tubes 32, and an annular frame 43 is installed on the vertical rod 42. An annular plate 44 is rotatably installed on the annular frame 43, and a plurality of circumferentially uniformly distributed linkage blocks 45 are slidably arranged on the circumferential surface of the annular plate 44, and an arc plate 46 is installed at one end of the linkage block 45 located inside the annular plate 44. At a certain moment, the arc plate 46 corresponding to the same annular plate 44 forms a full circle structure during the movement process, and a support block 47 matching the wing is evenly arranged on the side of the arc plate 46 away from the linkage block 45, and a return spring 48 is installed between the arc plate 46 and the corresponding annular plate 44.

[0083] The linkage blocks 45 corresponding to the same annular plate 44 are provided with a tightening rope 49 at one end away from the corresponding arc-shaped plate 46 , and a winding shaft 40 for winding the tightening rope 49 is installed on the corresponding annular plate 44 via a bearing.

[0084] During specific operation, when the support limit of the automobile aluminum profile 100 is completed, the winding shaft 40 is rotated at this time, and the fastening rope 49 is wound during the rotation of the winding shaft 40. During the winding process of the fastening rope 49, the linkage block 45 is driven to move toward the automobile aluminum profile 100. During the movement of the linkage block 45, the arc plate 46 is synchronously driven to move. At this time, the return spring 48 is stretched, and the angle of the automobile aluminum profile 100 is finely adjusted during the movement of the arc plate 46 so that the support block 47 is clamped in the gap between the adjacent wing pieces. At this time, the arc plate 46 corresponding to the same annular plate 44 forms a whole during the movement. The circular structure relatively limits the automotive aluminum profile 100 through the support block 47. When the automotive aluminum profile 100 moves back and forth, the arc plates 46 corresponding to the same annular plate 44 cooperate with each other to always perform passive straightening treatment on the automotive aluminum profile 100, reduce the possibility of deformation of the automotive aluminum profile 100, and improve the straightness of the automotive aluminum profile 100. At the same time, the support block 47 can always support and limit the wing, avoid the possibility of deformation of the wing caused by the annular plate 44 squeezing the wing, and further improve the surface straightness of the automotive aluminum profile 100.

[0085] The return spring 48 can reset the arc plate 46, and the annular frame 43 can give way to the annular plate 44, so as to ensure that the annular plate 44 can always rotate on the annular frame 43 during the rotation of the automobile aluminum profile 100, avoiding the possibility of rigid collision between the annular plate 44 and the annular frame 43.

[0086] Example 3: Reference Fig.11 The reciprocating plate 41 is slidably arranged on the reciprocating frame 21, a rack plate 411 is installed on the reciprocating frame 21, a rotating shaft 412 is installed on the horizontal frame 1 through a bearing, a reversing gear 413 meshing with the rack plate 411 is installed on the rotating shaft 412, a horizontal connecting rod 414 is installed on the reciprocating plate 41, and a rack plate 415 meshing with the reversing gear 413 is installed at one end of the horizontal connecting rod 414 away from the reciprocating plate 41.

[0087] During specific operation, during the movement of the reciprocating frame 21, the rack plate 1 411 and the reversing gear 413 are meshed with each other to drive the rotating shaft 412 to rotate. During the rotation of the rotating shaft 412, the reversing gear 413 synchronously drives the rack plate 2 415 to move. At this time, the moving directions of the rack plate 1 411 and the rack plate 2 415 are opposite, and thus the reciprocating plate 41 can make a reciprocating motion on the reciprocating frame 21 in the opposite direction to the reciprocating frame 21. During the reciprocating movement of the reciprocating plate 41, the vertical rod 42 and the annular frame 43 cooperate with each other to drive the arc plate 46 to actively straighten the automotive aluminum profile 100, and then the automotive aluminum profile 100 is straightened by the passive straightening of the arc plate 46 in combination with the active straightening, so as to improve the straightness of the automotive aluminum profile 100 after cooling.

[0088] The implementation principle of the present invention is:

[0089] (1): After the automobile aluminum profile 100 is formed, the automobile aluminum profile 100 is placed on the supporting shaft 24 corresponding to the supporting frame 23 through the existing transfer equipment (transfer robot, etc.), so that the supporting disc 241 and the supporting claw 242 cooperate with each other to support the automobile aluminum profile 100. At this time, the automobile aluminum profile 100 is located inside the annular tube 32 and is coaxial with each annular tube 32. At this time, the limit rod is reset. At this time, the supporting frame 1 22 is fixedly connected to the horizontal frame 1, and the supporting frame 1 22 and the supporting frame 2 23 cooperate with each other to support and limit the automobile aluminum profile 100 through the supporting shaft 24.

[0090] (2): Water is pumped into the annular tube 32, wherein a transition tube is installed between the annular tubes 32, and the transition tube is connected to the water outlet of an existing water pump (not shown in the figure). The existing water pump pumps water into the annular tube 32 through the transition tube, and then the water is sprayed out from the nozzle 33 after passing through the annular tube 32. The sprayed water mist can cool the outer surface of the automobile aluminum profile 100 and its surface fins.

[0091] (3): The existing driving motor drives the winding shaft 113 to rotate a certain number of times. During the rotation of the winding shaft 113, the traction rope 114 is wound. When the traction rope 114 is wound and rolled up, the reciprocating frame 21 is synchronously driven to move synchronously. The telescopic spring 111 is compressed due to the movement of the reciprocating frame 21 toward the side of the reversing shaft 115. At this time, the reciprocating frame 21 and the support frame 1 22 and the support frame 23 cooperate with each other through the supporting shaft 24 to synchronously drive the automobile aluminum profile 100 to move. After the winding shaft 113 rotates a certain number of times, the winding shaft 113 stops rotating. At this time, the output shaft of the driving motor drives the winding shaft 113 to reverse, and then the telescopic spring 111 is no longer constrained and resets. The reciprocating frame 21 and the support frame 1 22 and the support frame 23 cooperate with each other through the supporting shaft 24 to synchronously drive the automobile aluminum profile 100 to move away from the reversing shaft 115. Repeating the above actions can make the automobile aluminum profile 100 reciprocate along the length direction of the horizontal frame 1.

[0092] (4): When the winding shaft 113 rotates, the sleeve 212 is driven to rotate together. The sleeve 212 further drives the support shaft 25 to rotate through a belt drive. When the support shaft 25 rotates, the spray pipe 34 is driven to reciprocate inside the automotive aluminum profile 100 through the support protrusion. At this time, water is pumped into the spray pipe 34 by an existing water pump, and the water is sprayed toward the inner wall of the automotive aluminum profile 100 through the spray pipe 34, thereby cooling the automotive aluminum profile 100.
