Description

Technical Field

[0001] This invention relates to the field of aluminum liquid-cooled plate stamping and manufacturing technology, and in particular to a clamping device for preventing deformation of thin-walled parts used in aluminum profile processing. Background Technology

[0002] Liquid cooling plates are a highly efficient heat dissipation solution widely used in electronic devices, electric vehicle batteries, data center servers, and other fields. They are the core heat transfer components in liquid cooling systems, mainly used to efficiently transfer the heat generated by heat-generating components to the flowing coolant, which then carries the heat to the external radiator to dissipate it into the environment. Currently, liquid cooling plates on the market are mainly made of 1.5 mm thick 3003 aluminum alloy metal plates, which are formed by one-time stamping. They are especially suitable for mass production and standardization. However, the aluminum profiles used for processing liquid cooling plates often have local warping and deformation problems after stamping.

[0003] For example, Chinese invention patent CN113774204B discloses a clamping device and method for preventing warping deformation of aluminum alloy castings during heat treatment. Although this solution greatly reduces the warping deformation of A319 castings during cooling by setting pressure plates across both sides of a long concave groove at both ends of the top surface of the substrate, the middle part or the edge part far from the ends of the casting or stamped part may still have local warping deformation after stamping or during the cooling process due to the lack of a positioning clamping mechanism. For high-precision structural components such as liquid cooling plates, this may cause product defects and reduced heat conduction efficiency.

[0004] In view of this, a clamping device for preventing deformation of thin-walled parts used in aluminum profile processing is proposed, which can solve the above problems. Summary of the Invention

This can reduce the problem of local warping deformation caused by the structural stretching and expansion of the outer edge into the inner area of ​​the aluminum plate during the stamping process. 2. The present invention connects the vacuum pump to the internal vacuum chamber through a vacuum pump connection valve, which discharges the air under the aluminum profile and uses the suction force formed by the pressure from the bottom to further flatten and shape the aluminum profile, thereby further reducing the possibility of deformation during the aluminum profile processing. 3. This invention uses a servo motor to rotate, which in turn drives the screw sleeve to move up and down via a lead screw and a slide bar. When the screw sleeve slides up and down, the rotating wheel, under the action of the connecting rod being limited by the slot, causes the annular pressure plate to rotate 180 degrees forward and backward along with the connecting rod moving up and down along the slot. This avoids interference caused by the annular pressure plate above when the aluminum profile is finished and needs to be unloaded, and has the advantages of being more convenient to use and simpler to unload.

Detailed Implementation

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example: Please combine Figure 1 This embodiment of a thin-walled anti-deformation clamping device for aluminum profile processing includes a worktable 1. In this embodiment, the worktable 1 is a support component of a certain height. In other embodiments, the worktable 1 can be removed, and the liquid cooling plate for battery modules can be directly placed under the stamping die for stamping processing, which is also within the protection scope of this invention. Please combine Figure 1 As shown, a support 8 is installed on the upper side of the workbench 1, and a placement groove 7 is provided on the upper side of the support 8. In this embodiment, the support 8 is a rectangular cube structure with a hollow interior. It should be noted that the thickness of the placement groove 7 needs to be determined according to the specific liquid cooling plate stamping scenario. In this embodiment, the placement groove 7 does not have a groove or a protrusion structure. In other embodiments, a concave flow groove can be opened according to the distribution of coolant guide grooves in the liquid cooling plate. In addition, if the thickness of the aluminum profile is 1.5 mm, the groove depth of the placement groove 7 is lower than the thickness of the aluminum profile, which facilitates the self-centering positioning of the aluminum profile by the side clamps 16 on both sides. Please combine Figure 1 As shown, a reference plate 9 is fixedly connected to the support 8 at one side of the placement groove 7. The reference plate 9 serves as a marking position. When one side of the aluminum profile is initially placed, one side abuts against the reference plate 9. Please combine Figure 6 As shown, a vacuum chamber 31 is provided on the lower side of the support 8, and a vacuum pumping mechanism is provided on the outer side of the vacuum chamber 31. Multiple vacuum holes 26 are provided on the partition between the placement groove 7 and the vacuum chamber 31. It should be noted that in this embodiment, the vacuum chamber 31 serves as a centralized collection of the exhaust airflow from all the vacuum holes 26 and then discharges it uniformly from the vacuum pump connecting valve 10. This is based on the fact that the liquid cooling plate used for processing in this embodiment is a whole, that is, a one-time stamping without any grooves or holes. When the vacuum pump is started, there are no air leakage points on the top of the aluminum profile. If other aluminum profile processing embodiments have punching and air leakage on their surface structure, multiple grids can be set inside the vacuum chamber 31 to divide the space, that is, each grid corresponds to a vacuum hole 26, and each vacuum hole 26 is independently connected to a multi-port pipe of the vacuum pump body. This can maximize the use of pressure to achieve the effect of flattening the aluminum profile. Please combine Figure 6 and Figure 1As shown, in this embodiment, two dovetail grooves 30 are provided on both sides of the support 8. A dovetail slider 12 is slidably connected to the inner side of the two dovetail grooves 30 on each side. A side push rod 29 is fixedly connected to the upper side of each dovetail slider 12. A side clamping plate 16 is fixedly connected to one side of the two dovetail sliders 12 on each side. One end of each side clamping plate 16 is slidably connected to one side of the reference plate 9. A side clamping plate driving mechanism is provided on the upper side of the support 8 to make the two side clamping plates 16 move closer or further away from each other. An LED industrial control panel 18 is installed on one side of the workbench 1.

[0021] Through the above technical solution, two or more No. 1 dovetail sliders 12 distributed in a dispersed manner can provide stable support for the side clamping plate 16, which is conducive to improving the positioning and clamping accuracy and improving the quality of stamped products. Please combine Figure 1 As shown, the vacuum pumping mechanism includes a vacuum pump connection valve 10 installed on one side of the support 8, which is directly and quickly connected to the vacuum pump. Please combine Figure 1 As shown, the vacuum pump connecting valve 10 is connected to the vacuum chamber 31, and a pressure sensor 11 is installed on the other side of the support 8. The pressure sensor 11 is electrically connected to the LED industrial control panel 18. Through the above technical solution, the PLC control program built into the LED industrial control panel 18 can collect the current pressure inside the vacuum chamber 31 in real time through the air pressure sensor 11, and start and stop the vacuum pump through the control algorithm to ensure that the pressure inside the vacuum chamber 31 is in a safe state. Please combine Figure 5 As shown, the side clamping plate driving mechanism includes a second dovetail groove 27 opened on the side of the support 8 away from the reference plate 9, and a second dovetail slider 28 is slidably connected to the inner side of the second dovetail groove 27. It should be noted that in this embodiment, only one No. 2 dovetail slide groove 27 is provided on one side of the support 8. In other embodiments, other numbers of No. 2 dovetail slide grooves 27 can be provided according to actual needs, with no less than one. Theoretically, a larger number of No. 2 dovetail slide grooves 28 can provide more stable support force for the main push plate 20, thus making the main push plate 20 more accurate in movement and the system error of the whole system smaller, which is conducive to improving the quality of processed products. Please combine Figure 5As shown, an elastic reset mechanism is provided between the second dovetail slider 28 and the second dovetail groove 27. The upper side of the second dovetail slider 28 is fixedly connected to the main push plate 20. The two ends of the main push plate 20 are respectively fixedly connected to the side push plates 13. Two side push grooves 14 are opened on both sides of the side push plates 13. The two side push grooves 14 are arranged in a linear array. The two side push grooves 14 on each side are paired with two side push rods 29. The outer side of the side push rod 29 is slidably connected to the inner side of the corresponding side push groove 14. A dovetail slider drive mechanism is provided on one side of the worktable 1 to make the second dovetail slider 28 slide back and forth inside the second dovetail groove 27. With the above technical solution, when the side push plate 13 moves toward the side closer to the reference plate 9, the two side clamping plates 16 move closer to each other, thereby achieving clamping and positioning of the aluminum profile plate. Conversely, when the side push plate 13 moves away from the reference plate 9, the two side clamps 16 move away from each other, thus releasing the aluminum profile. Please combine Figure 7 As shown, the dovetail slider drive mechanism includes a running groove 32 and a slanted push groove 33 opened on the second dovetail slider 28. The slanted push groove 33 and the running groove 32 are connected and intersected at the edge. A slanted push block 23 is provided on the inner side of the slanted push groove 33. A slanted push block lifting mechanism that moves the slanted push block 23 up and down is provided on one side of the worktable 1.

[0022] With the above technical solution, since the inclined push groove 33 is opened at an angle inside the second dovetail slider 28, when the inclined push block 23 descends and enters the inclined push groove 33 from the upper port, the inclined push block 23 pushes the second dovetail slider 28 to move towards the reference plate 9, and the elastic component 34 is compressed and deformed. Conversely, when the inclined push block 23 is pulled out from inside the inclined push groove 33, the inclined push block 23 pulls the second dovetail slider 28 to move away from the reference plate 9, and the elastic component 34 rebounds and recovers. Please combine Figure 4 As shown, the inclined push block lifting mechanism includes a limiting cylinder 2 fixedly connected to the upper side of the worktable 1, and a slot 3 is provided on the outer side of the limiting cylinder 2; It should be noted that the layout of the card slot 3 in this embodiment is as follows: Figure 4 and Figure 2 As shown, the tracks at both ends of the card slot 3 are vertically opened, while the area between the two ends is a spiral curve with a 180-degree deflection. The spiral curve section is used to move the annular pressure plate 5 away from the support 8, which facilitates the loading and unloading of aluminum profiles; The bottom vertical track of the slot 3 is used to restrict the vertical downward movement of the connecting rod 19, which can ensure that the lower end of the inclined push block 23 accurately enters the upper port of the inclined push slot 33. Please combine Figure 3As shown, in this embodiment, a threaded sleeve 25 is slidably connected to the inner side of the limiting cylinder 2, and two sliding rods 21 are slidably connected to the threaded sleeve 25. The upper and lower ends of each sliding rod 21 are fixedly connected to the inner side of the limiting cylinder 2. A rotating wheel 24 is rotatably connected to the outer side of the threaded sleeve 25. The outer side of the rotating wheel 24 is slidably connected to the inner side of the limiting cylinder 2. A connecting rod 19 is fixedly connected to the outer side of the rotating wheel 24. The outer side of the connecting rod 19 is slidably connected to the slot 3. A connecting block 15 is fixedly connected to one end of the connecting rod 19. A longitudinal beam plate 17 is fixedly connected to the lower side of the connecting block 15. One side of the longitudinal beam plate 17 is fixedly connected to one side of the inclined push block 23. The outer side of the longitudinal beam plate 17 is fitted with the running groove 32. A connecting rod drive mechanism is provided on the upper side of the limiting cylinder 2 to make the connecting rod 19 swing along the slot 3. A pressing and positioning mechanism for pressing and positioning the aluminum profile from above is provided on the side of the connecting block 15 away from the connecting rod 19.

[0023] With the above technical solution, when the inclined push block 23 is inserted into or pulled out from the upper port of the inclined push groove 33, the outer side of the longitudinal beam plate 17 is slidably connected to the inner side of the running groove 32, and when the connecting rod 19 moves spirally with the deflection of the slot 3, the rotating wheel 24 rotates relative to the screw sleeve 25. Please combine Figure 4 As shown, the linkage drive mechanism includes a servo motor 4 mounted on the upper side of the limiting cylinder 2. The output end of the servo motor 4 extends into the limiting cylinder 2, and a lead screw 22 is fixedly connected to the output end of the servo motor 4. The lead screw 22 is threadedly connected to the screw sleeve 25. The lower end of the lead screw 22 is rotatably connected to the bottom side inside the limiting cylinder 2. The servo motor 4 is electrically connected to the LED industrial control panel 18.

[0024] Please combine Figure 2 As shown, the pressing and positioning mechanism includes an annular pressure plate 5 fixedly connected to one side of the connecting block 15, and a rubber gasket 6 is installed on the outer side of the annular pressure plate 5. In this embodiment, the annular pressure plate 5 is a rectangular structure. In other embodiments, it can be adjusted according to the actual edge structure characteristics of the liquid cooling plate, which is also within the scope of protection of this invention. It should be noted that the rubber gasket 6 can not only improve the gripping effect on the aluminum plate by increasing the friction, but also improve the air tightness, making the vacuum pump operation more efficient and the air pressure adsorption force stronger. Please combine Figure 5 As shown, the elastic reset mechanism includes multiple elastic components 34 disposed between the second dovetail slider 28 and the second dovetail groove 27, and the number of multiple elastic components 34 is not less than two.

[0025] Please combine Figure 4 As shown, the deflection angle between the upper and lower ends of the card slot 3 is 180 degrees. In this embodiment, the upper and lower ends of the card slot 3 can move completely in one go, achieving a deflection angle of 180 degrees. In other embodiments, different deflection angles can be set according to actual needs. Please combine Figure 6 As shown, the number of multiple No. 1 dovetail sliders 12 on each side is no less than two.

[0026] The implementation principle of a thin-walled anti-deformation clamping device for aluminum profile processing in this application embodiment is as follows: In this embodiment scenario, the device is used to stamp a battery liquid cooling plate in one go using 3003 aluminum alloy with a thickness of 1.5 mm. After clamping the aluminum alloy, the aluminum alloy is stamped and formed by external stamping equipment. First, the processed aluminum profile is placed in the placement groove 7. Then, the servo motor 4 and the vacuum pump connected to the vacuum pump valve 10 are started through the LED industrial control panel 18. The vacuum pump discharges the air below the aluminum profile from the vacuum hole 26 and the vacuum chamber 31. The suction force generated by the external air pressure can first perform preliminary positioning of the aluminum profile. At the same time, the servo motor 4 starts and drives the lead screw 22 to rotate. Under the limiting action of the slide bar 21 on the screw sleeve 25, the lead screw 22 can push the rotating wheel 24 to slide up and down through the screw sleeve 25. Since one end of the connecting rod 19 is fixedly connected to the outside of the rotating wheel 24 and the screw sleeve 25 is rotatably connected to the rotating wheel 24, while the other end is fixedly connected to the outside of the annular pressure plate 5, under the action of the connecting rod 19 passing through the slot 3 and being limited by the slot 3, the annular pressure plate 5 can move up and down with the connecting rod 19 while rotating 180 degrees forward and backward. It should be noted that in this embodiment, the connecting rod 19 moves directly inside the slot 3 by sliding motion. In other embodiments, a cylindrical roller can be sleeved on the outside of the connecting rod 19. When the connecting rod 19 moves, the roller can change the sliding friction between the connecting rod 19 and the slot 3 to rolling friction, thereby reducing the friction in the slot 3 when the connecting rod deflects and making the movement smoother. When the connecting block 15 descends along the slot 3 along the connecting rod 19, the inclined push block 23 can enter from the upper port of the inclined push groove 33. During the descent, it is squeezed against the second dovetail slider 28, thereby pushing the second dovetail slider 28 to slide to one side along the second dovetail slide groove 27. The elastic component 34 between the two undergoes compression deformation. The movement of the second dovetail slider 28 drives the upper main push plate 20 to move to one side, thereby driving the side push plates 13 on both sides to move to one side. Under the action of the side push groove 14 opened on the side push plate 13, the side push rod 29 slidably connected to the inner side of the side push groove 14 can push the first dovetail slider 12 on both sides to move back and forth along the first dovetail slide groove 30 inward, thereby pushing the side clamping plates 16 on both sides to move closer or further away from each other, and realizing the function of clamping and positioning the aluminum profile from both sides. When the side clamps 16 on both sides abut against the aluminum profile sheet from both sides, and the main push plate 20 abuts against the aluminum profile sheet from the side opposite to the reference plate 9, the annular pressure plate 5 and the rubber gasket 6 can press and fix the edge of the aluminum profile sheet from above. Through the sealing of the aluminum plate edge and the pressure adsorption effect created by the vacuum pump, abnormal local warping deformation of the aluminum profile sheet can be effectively avoided.

[0027] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
