Description

Technical Field

[0001] The invention relates to the technical field of stainless steel liquid cooling pipe welding processing, in particular to a welding device for stainless steel liquid cooling 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, and the high temperature environment will affect the performance of electronic components. Liquid cooling is an effective technical means to meet the heat dissipation needs 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 the heat can be transferred in a controlled and directional manner, liquid cooling has become the preferred cooling method in more and more occasions.

[0003] An efficient liquid cooling system requires the support of a liquid cooling module. The design of the liquid cooling module must take into account the heat dissipation requirements, the actual application environment, the drive of the liquid circuit, the physical properties of the cooling liquid, the manufacturing of the cooling module, and other requirements to fully exert the effectiveness of liquid cooling. Under 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 form of the flow channel and the length of the relevant process, the flow resistance of the serpentine channel is the largest under different flow conditions, mainly because the average flow velocity of the serpentine channel is higher, and the average flow velocity in the turbulence design is lower. The serpentine channel process is longer, and the temperature of the fluid is higher when it dissipates heat to the heating element at the outlet, so the maximum temperature is relatively high. At present, most electronic equipment at home and abroad use cold plate liquid indirect cooling technology with high cooling efficiency to solve the heat dissipation problem. Cold plates are usually interconnected by cold pipe assemblies to form a liquid cooling circuit. Liquid cooling pipelines are mainly used to connect transition soft (hard) pipes between liquid cooling sources and equipment, between equipment and equipment, and between equipment and other pipelines. There are two types: hoses and metal pipes.

[0005] The patent document with announcement number CN118848172A discloses an intelligent argon arc welding device for bellows and its welding process, which realizes intermittent knocking on the surface of the bellows through the rotation of the bellows and the intermittent contact between the first and second guide wheels. This knocking action effectively eliminates the internal stress generated during the welding process, reduces the deformation, cracks and other defects that may occur after welding, and improves the stability of the welded joint and the service life of the product; utilizing 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. For bellows with smaller diameters, a smaller knocking force is used to avoid overheating and deformation; for bellows with larger diameters, 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, it is found that the above technical solution has the following technical problems:

[0007] The intelligent processing argon arc welding device for corrugated pipes and its welding process are relatively stable in fixation and have good welding effect when performing welding work on tubular devices. Even when applied to welding of cold liquid pipes, they can maintain relatively good advantages. However, in actual application, the stainless steel cold liquid pipe will be bent into a serpentine state for welding work. Since it is not easy for the welding device to clamp devices other than tubular devices, it is difficult to weld tubular devices in a serpentine state or a special-shaped state, and the device has high limitations.

[0045] like 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, the outside of the adapter ring B510 is provided with a bearing seat 506, and the bottom of the bearing seat 506 is assembled and connected with a fixed stand 502;

[0046] Among them, by assembling the fixed stand 502 to the top of the supporting plate 9, when the stainless steel liquid cooling pipe head 10 is clamped and fixed to the inside of the three-jaw chuck B501, the stainless steel liquid cooling pipe head 10 can be fixed to the three-jaw chuck B501, restricting the stainless steel liquid cooling pipe head 10 from moving or rotating along the axial direction;

[0047] Secondly, in order to facilitate the three-jaw chuck B501 to control the rotation of the stainless steel liquid cooling pipe head 10, such as Figure 5 As shown, a transmission shaft 509 is internally pin-connected at one end of the adapter ring B510, a transmission pulley 508 is integrally molded at one end of the transmission shaft 509, a motor base frame 504 is assembled and connected to one side of the bottom of the fixed stand 502, and a motor B503 is assembled and connected to the top of the motor base frame 504, and the transmission pulley 508 is also assembled and fixed to one end of the rotating shaft of the motor B503 by a pin key, and a plurality of transmission belts 505 are arranged between the two transmission pulleys 508, so that the transmission function of the plurality of transmission belts 505 between the two transmission pulleys 508 can be achieved, and the adapter ring B510 connected to the transmission shaft 509 can be driven to rotate by the motor B503, the two transmission pulleys 508 and the transmission belts 505, and further the stainless steel liquid cooling pipe head 10 inside the three-jaw chuck B501 can be driven to rotate;

[0048] At the same time, by integrally forming a support shaft 507 on one side of the transmission pulley 508 connected to the motor B503, when one end of the support shaft 507 is installed to the inside of the fixed frame 502 through a bearing, the stability of the motor B503 controlling the rotation of a transmission pulley 508 and making multiple transmission belts 505 circulate and roll with the cooperation of another transmission pulley 508 can be improved.

[0049] Embodiment 2:

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

[0051] Among them, by passing one end of the top of the stainless steel liquid cooling tube body 2 from the adapter ring A404 to the top of the other side of the C-shaped stand 401, it can be clamped and fixed by the three-jaw chuck A410 to limit the stainless steel liquid cooling tube body 2 from moving or rotating along the axis of the clamping end inside the three-jaw chuck A410, and one end of the stainless steel liquid cooling tube body 2 is docked with the stainless steel liquid cooling tube head 10, and during the welding process by the welding device main body 3, one end of the bottom of the stainless steel liquid cooling tube body 2 is movably connected to the inner side of the C-shaped stand 401;

[0052] Secondly, in order to make the clamping structure A4 carry the stainless steel liquid cooling tube body 2 to move along a fixed track toward the clamping structure B5, such as Figure 5 and Figure 6 As shown, a limiting bottom plate 405 is integrally formed on one side of the bottom of the C-shaped stand 401, and a positioning slide bar 408 is integrally formed on the top of the limiting bottom plate 405. A pneumatic push rod B406 is arranged on the other side of the bottom of the C-shaped stand 401, and a buckle plate 409 is assembled and connected to one end of the pneumatic push rod B406. A circular groove 12 is processed on the bottom of the fixed stand 502, and a supporting bottom frame 407 is assembled and connected to the supporting bottom frame 407 by assembling the supporting bottom frame 407 on the supporting bottom frame 407. At the top of the plate 9, the buckle plate 409 is assembled and fixed with the C-shaped frame 401. When the pneumatic push rod B406 is working, the control limit bottom plate 405 is movably connected to the bottom of the fixed frame 502, the positioning slide bar 408 is movably connected to the inside of the circular groove 12, and the limit bottom plate 405 is movably connected to the bottom of the motor frame 504. The fixed frame 502 is used as the limit bottom plate 405 to limit the position, which can ensure that the clamping structure A4 is close to the clamping structure B5 or away from the clamping structure B5.

[0053] At the same time, the top surface of the C-shaped stand 401 is processed with an arc groove 11. In the process of controlling the clamping structure A4 to approach or move away from the clamping structure B5, the C-shaped stand 401 can be movably connected to the bottom of the three-jaw chuck B501 through the arc groove 11, ensuring that the stainless steel liquid cooling tube body 2 on the clamping structure A4 is docked 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 frame 401 to the movement on the top of the supporting plate 9 and reduce the wear between the C-shaped frame 401 and the supporting plate 9, as shown in FIG. Figure 7 The bottom of the C-shaped frame 401 and the limiting bottom plate 405 are processed with a storage groove 13, and the top inner wall of the storage groove 13 is assembled and connected with a plurality of rollers 411. By making the plurality of rollers 411 rollingly connected to the top of the supporting plate 9, the pneumatic push rod B406 can control the C-shaped frame 401 to move toward the fixed frame 502 to reduce the resistance.

[0055] Embodiment 3:

[0056] Based on Example 1 and Example 2, this example introduces the specific structure of the pipe follower structure 1, which includes a mounting ring 102, and pneumatic push rods A109 are hingedly connected to the inner walls on both sides of the bottom of the mounting ring 102, and one end of the pneumatic push rod A109 is hingedly connected to a pull arm 110, and one end of the two pull arms 110 is hingedly connected to the same bracket 106;

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

[0058] At the same time, in the process that the pneumatic push rod B406 controls the C-shaped stand 401 to drive the stainless steel liquid cooling tube body 2 on the three-jaw chuck A410 to approach or move away from the stainless steel liquid cooling tube head 10, the bottom of the stainless steel liquid cooling tube body 2 can be movably connected to the inner side of the bracket 106, ensuring that the bracket 106 can always support the bracket 106;

[0059] Secondly, in order to allow the bracket 106 to move up and down on the diameter line inside the mounting ring 102 to adapt to the height of the stainless steel liquid cooling tube body 2 of different specifications, such as Figure 4 As shown, two guide rods 107 are threadedly connected at the center of the bottom inner wall of the erection ring 102, so that the two guide rods 107 are symmetrically arranged on both sides of the bracket 106. When the two pneumatic push rods A109 work synchronously, the two sides of the bracket 106 can be slidably connected to the outside of the two guide rods 107 to control the bracket 106 to move up and down inside the erection ring 102;

[0060] like Figures 8 to 10 As shown, the outer wall of one side of the mounting ring 102 is processed with a case receiving ring groove B6, and the inner wall of the case receiving ring groove B6 is processed with a gear ring 104, the bottom of the gear ring 104 is meshedly connected with a gear 105, and one side of the gear 105 is assembled and connected with a motor A103;

[0061] Support ring frames 101 are provided on the outside of both sides of the mounting ring 102, and receiving ring grooves A14 are processed on the inner walls of the two support ring frames 101, and multiple rolling rods 108 are provided inside the receiving ring grooves A14;

[0062] Among them, by making the motor A103 assembled and connected to the top of the support plate 9, the support ring frame 101 is C-shaped, and the support ring frame 101 is assembled and connected to the top of the corner column 8, the erection ring 102 can be supported by multiple rollers 108 on the inner side of the support ring frame 101 and rotate. When the motor A103 drives the erection ring 102 to rotate through the gear ring 104, the bottom of the erection ring 102 is rotatably connected to the inside of the support plate 9, and the bracket 106 used to support the stainless steel liquid cooling tube body 2 is affected by the tension arm 110, the pneumatic push rod A109 and the bracket 106, and supported by the two guide rods 107, so as to drive the stainless steel liquid cooling tube body 2 to rotate;

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

[0064] Specifically, when the welding device for the stainless steel liquid cooling tube is used 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 pipe head 10 into the interior of the three-jaw chuck B501, and use the known operation means to clamp and fix the stainless steel liquid cooling pipe head 10 with 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 stand 401, and use the three-jaw chuck A410 to clamp and fix the stainless steel liquid cooling tube body 2 using known operating means (at this time, the stainless steel liquid cooling tube body 2 is in a naturally drooping state);

[0067] Next, the two pneumatic push rods A109 are started, so that the two pneumatic push rods A109 pull the bracket 106 outside the two guide rods 107 from the bottom to the top through the pull arm 110 until it is supported at the bottom of the stainless steel liquid cooling tube body 2, thereby supporting the stainless steel liquid cooling tube body 2;

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

[0069] Finally, the welding device body 3 extends the welding head to the docking area between the stainless steel liquid-cooling tube body 2 and the stainless steel liquid-cooling tube head 10, so that the motor B503 and the motor A103 work synchronously. On the one hand, the motor B503 controls a transmission pulley 508 to rotate, and with the cooperation of another transmission pulley 508, multiple transmission belts 505 are circulated and rolled, so that the transmission pulley 508 drives the adapter ring B510 outside the transmission shaft 509 to rotate, and then controls the stainless steel liquid-cooling tube head 10 in the three-jaw chuck B501 to rotate; on the other hand, the motor A103 drives the mounting ring 102 to rotate through the gear ring 104, so that the mounting ring 102 is supported and rotated by multiple rollers 108 on the inner side of the support ring frame 101, and its bottom is rotatably connected to the inside of the support plate 9, and can drive the stainless steel liquid-cooling tube body 2 to rotate with the support of the bracket 106 supporting the stainless steel liquid-cooling tube body 2 and the two guide rods 107;

[0070] At the same time, when the stainless steel liquid-cooled tube body 2 rotates with the mounting ring 102, the rotation speeds of the stainless steel liquid-cooled tube body 2 and the stainless steel liquid-cooled tube head 10 are the same, which makes it easy for the welding device body 3 to weld the stainless steel liquid-cooled tube body 2 and the stainless steel liquid-cooled tube head 10 together, avoiding torsional stress during welding, thereby satisfying the rotation of the stainless steel liquid-cooled tube head 10 on one side of the top of the clamping structure B5. The tube follower structure 1 holds the stainless steel liquid-cooled tube body 2 and rotates synchronously with the stainless steel liquid-cooled tube head 10 on the top of the clamping structure A4, supporting the welding device body 3 to weld and fix the docking interface of the stainless steel liquid-cooled tube body 2 and the stainless steel liquid-cooled tube head 10.

[0071] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, 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 methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
