Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel liquid-cooled pipe welding and processing, and specifically to a welding device for stainless steel liquid-cooled pipes. Background Art

[0002] With the rapid development of electronic technology, the total power density of electronic components has increased significantly while the physical size has become smaller and smaller. Moreover, a high-temperature environment will affect the performance of electronic components. Liquid cooling is an effective technical means to meet the heat dissipation requirements of high heat flux density electronic components. Since the heat load capacity of the liquid cooling system is equivalent to 5 times that of the air cooling system, and heat can be controllably transferred in a directional manner, liquid cooling has become the preferred cooling method in more and more scenarios.

[0003] An efficient liquid cooling system requires the support of a liquid cooling module. The design of the liquid cooling module needs to consider various requirements such as heat dissipation needs, actual application environment, driving of the liquid circuit, physical properties of the cooling liquid, and manufacturing of the cooling module in order to fully exert the effectiveness of liquid cooling. At different flow rates, the heat transfer performance of the serpentine heat exchange flow channel is worse than that of the circular turbulent flow channel and the square turbulent flow channel, and the flow pressure drop is slightly larger.

[0004] Due to the differences in the flow channel form and the length of the relevant processes, under different flow rate conditions, the flow resistance of the serpentine channel is the largest, mainly because the average flow velocity of the serpentine channel is relatively high, while the average flow velocity in the turbulent flow design is relatively low. The serpentine channel has a longer process, and the temperature of the fluid is relatively high when dissipating heat from the heating element at the outlet position, so the maximum temperature is relatively large. Currently, most domestic and foreign electronic devices use the cold plate liquid indirect cooling technology with high cooling efficiency to solve the heat dissipation problem. Cold plates are usually interconnected by a cold pipe assembly to form a liquid cooling circuit. Liquid cooling pipelines are mainly used for the transition soft (hard) pipe connections between the liquid cooling source and the equipment, between equipment and equipment, and between equipment and other pipelines, and there are two types: flexible hoses and metal pipes.

[0005] The patent document with the publication number CN118848172A, a bellows intelligent processing argon arc welding device and its welding process, realizes the intermittent knocking on the surface of the bellows through the rotation of the bellows fitting and the intermittent contact between the first and second guide wheels. This knocking effect effectively eliminates the internal stress generated during the welding process, reduces defects such as deformation and cracks that may occur after welding, and improves the stability of the welded joint and the service life of the product; by using the deformation of the telescopic cylinder and the balance adjustment mechanism of air pressure and spring force, the device can automatically adjust the knocking force of the knocking block on the bellows fitting. For bellows fittings with a smaller diameter, a smaller knocking force is used to avoid overheating and deformation; for bellows fittings with a larger diameter, the knocking force is increased to ensure the full fusion of the welded joint and the stability of the quality.

[0006] However, in the process of implementing the above technical solution, the following technical problems are found in the above technical solution:

[0007] When the argon arc welding device for intelligent processing of bellows and its welding process are used for welding tube-like devices, the fixation is relatively stable and the welding effect is good. Even when applied to the welding of cold liquid pipes, it can maintain relatively good advantages. However, in the actual application process, the stainless steel cold liquid pipe will be bent into a snake shape for welding work. Since the welding device is not easy to clamp devices other than tube-like devices, it is difficult to weld tube-like devices in a snake shape or an abnormal shape, and the limitation is relatively high.

[0043] Embodiment 1:

On the top of the clamping structure A4, a stainless steel liquid-cooled pipe body 2 passing through the inside of the pipe-driven structure 1 is assembled and connected. At the bottom of the welding device main body 3, a machine tool 7 is provided. At the bottom of the machine tool 7, a support plate 9 is provided. Corner posts 8 are assembled and fixed between the four corners of the machine tool 7 and the support plate 9; the pipe-driven structure 1 is assembled to the top of one end of the machine tool 7, the clamping structure B5 passes through the inside of the other end of the machine tool 7 and is assembled and connected to the top of the support plate 9, and the clamping structure A4 is movably connected inside the machine tool 7;

[0045] As shown in Figure 5As shown, the clamping structure B5 includes a three-jaw chuck B501. One side of the three-jaw chuck B501 is assembled and connected with an adapter ring B510. An outer bearing seat 506 is provided on the adapter ring B510. The bottom of the bearing seat 506 is assembled and connected with a fixed upright frame 502;

[0046] Among them, by assembling and connecting the fixed upright frame 502 to the top of the supporting plate 9, when the stainless steel liquid cooling tube head 10 is clamped and fixed inside the three-jaw chuck B501, the stainless steel liquid cooling tube head 10 can be fixed to the three-jaw chuck B501, restricting the movement or rotation of the stainless steel liquid cooling tube head 10 along the axial direction;

[0047] Secondly, to facilitate the three-jaw chuck B501 to control the rotation of the stainless steel liquid cooling tube head 10, as Figure 5 shown, one end of the adapter ring B510 is pin-connected with a transmission shaft 509 inside.

One side of the bottom of the fixed upright frame 502 is assembled and connected with a motor base frame 504. The top of the motor base frame 504 is assembled and connected with a motor B503. By making the transmission belt pulley 508 also be assembled and fixed to one end of the rotating shaft of the motor B503 through a pin key, and arranging a plurality of transmission belts 505 between the two transmission belt pulleys 508, enabling the plurality of transmission belts 505 to perform their transmission functions between the two transmission belt pulleys 508, the adapter ring B510 connected to the transmission shaft 509 can be driven to rotate by the motor B503, the two transmission belt pulleys 508 and the transmission belts 505, further driving the stainless steel liquid cooling tube head 10 inside the three-jaw chuck B501 to rotate;

[0048] Meanwhile, by integrally forming a support shaft 507 on one side of the transmission belt pulley 508 connected to the motor B503, when one end of the support shaft 507 is installed inside the fixed upright frame 502 through a bearing, the stability of the motor B503 controlling the rotation of one transmission belt pulley 508 and enabling the plurality of transmission belts 505 to circulate and roll under the cooperation of the other transmission belt pulley 508 can be improved.

[0049] Embodiment 2:

[0050] Based on Embodiment 1, this embodiment introduces the specific structure of the clamping structure A4, as Figures 1 to 3 , Figure 5 and Figure 7 shown, the clamping structure A4 includes a C-shaped upright frame 401. A vertical plate 402 is integrally formed at the top of one side of the C-shaped upright frame 401. A three-jaw chuck A410 is provided on one side of the vertical plate 402. One side of the three-jaw chuck A410 is assembled and connected with an adapter ring A404. One end of the adapter ring A404 is rotatably connected inside the vertical plate 402. One end of the adapter ring A404 is assembled and connected with a snap ring 403;

[0051] Among them, by passing one end of the top of the stainless steel liquid cooling tube body 2 through the adapter ring A404 to the top on the other side of the C-shaped support 401, it can be clamped and fixed by the three-jaw chuck A410 to restrict the movement or rotation of the stainless steel liquid cooling tube body 2 along the axis of the clamping end inside the three-jaw chuck A410. During the welding process of docking one end of the stainless steel liquid cooling tube body 2 with the stainless steel liquid cooling tube head 10 by the welding device main body 3, the other end of the bottom of the stainless steel liquid cooling tube body 2 is movably connected to the inner side of the C-shaped support 401;

[0052] Secondly, in order to make the clamping structure A4 carry the stainless steel liquid cooling tube body 2 and move along a fixed track towards the clamping structure B5, as Figure 5 and Figure 6 shown, one side of the bottom of the C-shaped support 401 is integrally formed with a limit bottom plate 405, the top of the limit bottom plate 405 is integrally formed with a positioning slide bar 408, the other side of the bottom of the C-shaped support 401 is provided with a pneumatic push rod B406, one end of the pneumatic push rod B406 is assembled and connected with a clamping plate 409, a circular groove 12 is processed at the bottom of the fixed support 502, the other end of the pneumatic push rod B406 is assembled and connected with a support bottom frame 407. By assembling and connecting the support bottom frame 407 to the top of the support plate 9 and fixing the clamping plate 409 to the C-shaped support 401, when the pneumatic push rod B406 works, it can control the limit bottom plate 405 to be movably connected to the bottom of the fixed support 502, and the positioning slide bar 408 to be movably connected inside the circular groove 12. And the limit bottom plate 405 is movably connected to the bottom of the motor bottom frame 504. Using the fixed support 502 to limit the limit bottom plate 405 can ensure the movement path of the clamping structure A4 approaching or moving away from the clamping structure B5;

[0053] At the same time, an arc groove 11 is processed on the top surface of the C-shaped support 401. During the process of controlling the clamping structure A4 to approach or move away from the clamping structure B5, the C-shaped support 401 can be movably connected to the bottom of the three-jaw chuck B501 through the arc groove 11 to ensure the docking of the stainless steel liquid cooling tube body 2 on the clamping structure A4 with the stainless steel liquid cooling tube head 10 on the clamping structure B5;

[0054] Furthermore, in order to reduce the resistance of the C-shaped support 401 moving on the top of the support plate 9 and reduce the wear between the C-shaped support 401 and the support plate 9, as Figure 7 shown. Receiving strip grooves 13 are processed at the bottoms of both the C-shaped support 401 and the limit bottom plate 405. A plurality of rollers 411 are assembled and connected to the inner wall at the top of the receiving strip grooves 13. By making the plurality of rollers 411 rollingly connected to the top of the support plate 9, the resistance can be reduced when the pneumatic push rod B406 controls the C-shaped support 401 to move towards the fixed support 502.

[0055] Example 3:

[0056] Based on Embodiment 1 and Embodiment 2, this embodiment introduces the specific structure of the pipe follower structure 1. The pipe follower structure 1 includes an erection ring 102. At both inner wall sides of the bottom of the erection ring 102, pneumatic push rods A109 are hingedly connected. One end of each pneumatic push rod A109 is hingedly connected to a pull arm 110, and one ends of the two pull arms 110 are hinged to the same bracket 106;

[0057] Among them, by making the cross-section of the bracket 106 be V-shaped, when one end of the top of the stainless steel liquid-cooled pipe body 2 is clamped inside the three-jaw chuck A410, the bottom of the three-jaw chuck A410 can be lapped on the top of the bracket 106 to ensure the stability of the stainless steel liquid-cooled pipe body 2 away from the connection end with the three-jaw chuck A410;

[0058] At the same time, during the process of the pneumatic push rod B406 controlling the C-shaped upright frame 401 to drive the stainless steel liquid-cooled pipe body 2 on the three-jaw chuck A410 to approach or move away from the stainless steel liquid-cooled pipe head 10, the bottom of the stainless steel liquid-cooled pipe body 2 can be movably connected to the inside of the bracket 106, ensuring that the bracket 106 can always support the bracket 106;

[0059] Secondly, in order to enable the bracket 106 to move up and down on the diameter line inside the erection ring 102 to adapt to the heights of stainless steel liquid-cooled pipe bodies 2 of different specifications, as Figure 4 shown, two guide rods 107 are threadedly connected to the center of the inner wall of the bottom of the erection ring 102, and the two guide rods 107 are symmetrically arranged on both sides of the bracket 106. When the two pneumatic push rods A109 work synchronously, both sides of the bracket 106 can be slidably connected to the outside of the two guide rods 107 to control the up and down movement of the bracket 106 inside the erection ring 102;

[0060] As Figures 8 to 10 shown, a receiving ring groove B6 is machined on the outer wall of one side of the erection ring 102. A toothed ring 104 is machined on the inner wall of the receiving ring groove B6. A gear 105 is meshed and connected to the bottom of the toothed ring 104, and a motor A103 is assembled and connected to one side of the gear 105;

[0061] Support ring frames 101 are arranged on the outside of both sides of the erection ring 102. Receiving ring grooves A14 are machined on the inner walls of the two support ring frames 101, and a plurality of roller rods 108 are arranged inside the receiving ring grooves A14;

[0062] Among them, by assembling and connecting the motor A103 to the top of the supporting plate 9, and the support ring frame 101 being C-shaped and assembled and connected to the top of the corner column 8, the erection ring 102 can rotate supported by a plurality of roller bars 108 inside the support ring frame 101. When the motor A103 drives the erection ring 102 to rotate through the toothed ring 104, the bottom of the erection ring 102 is rotationally connected to the inside of the supporting plate 9, and the bracket 106 for supporting the stainless steel liquid cooling tube body 2, affected by the tension arm 110, the pneumatic push rod A109 and the bracket 106, and supported by the two guide rods 107, drives the stainless steel liquid cooling tube body 2 to rotate;

[0063] In this state, the stainless steel liquid cooling tube body 2 drives the three-jaw chuck A410 to rotate (supported by the adapter ring A404 and the vertical plate 402 in cooperation, and a bearing is arranged between the adapter ring A404 and the vertical plate 402 to reduce the rotational resistance), so as to meet the requirement that there is no relative rotation during the butt welding process of the stainless steel liquid cooling tube body 2 and the stainless steel liquid cooling tube head 10, thereby avoiding torsional stress.

[0064] Specifically, when using the welding device for the stainless steel liquid cooling tube to weld the stainless steel liquid cooling tube body 2 and the stainless steel liquid cooling tube head 10:

[0065] First, insert one end of the stainless steel liquid cooling tube head 10 into the inside of the three-jaw chuck B501, and use a well-known operation method to clamp and fix the stainless steel liquid cooling tube head 10 by the three-jaw chuck B501;

[0066] Then, insert one end of the top of the stainless steel liquid cooling tube body 2 into the inside of the three-jaw chuck A410, so that one end of the stainless steel liquid cooling tube body 2 passes through the adapter ring A404 and extends to the top of the C-shaped vertical frame 401, and use a well-known operation method to clamp and fix the stainless steel liquid cooling tube body 2 by the three-jaw chuck A410 (at this time, the stainless steel liquid cooling tube body 2 is in a natural hanging state);

[0067] Next, start the two pneumatic push rods A109, so that the two pneumatic push rods A109 pull the bracket 106 to move from the bottom to the top outside the two guide rods 107 through the tension arm 110 until it supports the bottom of the stainless steel liquid cooling tube body 2, achieving the effect of supporting the stainless steel liquid cooling tube body 2;

[0068] Furthermore, start the pneumatic push rod B406, so that the pneumatic push rod B406 pushes the C-shaped vertical frame 401 to approach the fixed vertical frame 502 through the buckle plate 409 and under the support of the support chassis 407 (in this state, the support chassis 407 is movably connected to the bottom of the fixed vertical frame 502, and the positioning slide bar 408 is movably connected to the inside of the circular groove 12), until the C-shaped vertical frame 401 moves to the bottom of the three-jaw chuck B501 through the arc groove 11, making one end of the top of the stainless steel liquid cooling tube body 2 dock with the stainless steel liquid cooling tube head 10;

[0069] Finally, the main body 3 of the welding device extends the welding head to the docking area of the stainless steel liquid-cooled pipe body 2 and the stainless steel liquid-cooled pipe head 10, and makes the motor B503 and the motor A103 work synchronously. On the one hand, the motor B503 controls the rotation of a transmission pulley 508, and drives the cyclic rolling of a plurality of transmission belts 505 with the cooperation of another transmission pulley 508, so that the transmission pulley 508 drives the adapter ring B510 outside the transmission shaft 509 to rotate, and then controls the rotation of the stainless steel liquid-cooled pipe head 10 inside the three-jaw chuck B501. On the other hand, the motor A103 drives the erection ring 102 to rotate through the toothed ring 104, so that the erection ring 102 rotates supported by a plurality of roller bars 108 inside the support ring frame 101, and its bottom is rotatably connected to the inside of the supporting plate 9, and can drive the stainless steel liquid-cooled pipe body 2 to rotate with the support of the bracket 106 for supporting the stainless steel liquid-cooled pipe body 2 and the two guide rods 107.

[0070] At the same time, during the rotation of the stainless steel liquid-cooled pipe body 2 following the erection ring 102, the rotation speeds of the stainless steel liquid-cooled pipe body 2 and the stainless steel liquid-cooled pipe head 10 are the same, which is convenient for the main body 3 of the welding device to weld the stainless steel liquid-cooled pipe body 2 and the stainless steel liquid-cooled pipe head 10 together, avoiding the generation of torsional stress during the welding process, so as to meet the requirement that the stainless steel liquid-cooled pipe head 10 rotates on one side of the top of the clamping structure B5, the pipe follower structure 1 holds the stainless steel liquid-cooled pipe body 2 and rotates synchronously with the stainless steel liquid-cooled pipe head 10 at the top of the clamping structure A4, and the support welding device main body 3 welds and fixes the docking port of the stainless steel liquid-cooled pipe body 2 and the stainless steel liquid-cooled pipe head 10.

[0071] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
