Description

Technical Field

[0001] This utility model relates to the field of heat pipe production equipment, and in particular to a copper pipe cutting and welding mechanism for heat pipes. Background Technology

[0002] A heat pipe is a high-efficiency heat transfer element used for mold cooling. It achieves heat exchange through the liquid-gas phase change cycle of the internal refrigerant, thereby achieving the purpose of heat conduction. In the heat pipe production process, after the copper tube workpiece undergoes liquid injection, vacuuming, and sealing processes, the excess copper tube workpiece needs to be cut and welded to refine the workpiece.

The conversion between the cutting and welding processes requires repositioning the workpiece, which is not only prone to human error but also wastes a lot of manpower, material resources, and time, resulting in low production efficiency and failing to meet the needs of modern large-scale production.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please refer to Figures 1-5 This utility model provides a copper tube cutting and welding mechanism for heat-conducting pipes, including an operating platform 1, a tube moving device 2, a lifting device 3, a cutting device 4, and a welding device 5; The lifting device 3 includes a lifting bracket 31, a lifting drive assembly 32, and a lifting plate 33; the cutting device 4 is disposed on the lifting plate 33; the welding device 5 is disposed on the lifting bracket 31, and the welding device 5 is located at the downstream end of the cutting device 4. The tube transfer device 2 is mounted on the operating platform 1, and the lifting bracket 31 is mounted on the outside of the tube transfer device 2. The tube transfer device 2 is used to clamp the heat-conducting tube workpiece and drive the heat-conducting tube workpiece to move along the Y-axis direction. The lifting drive assembly 32 is mounted on the lifting bracket 31. The lifting drive assembly 32 is connected to the lifting plate 33 and is used to drive the lifting plate 33 to move along the Z-axis direction.

[0020] The lifting bracket 31 is used to mount the lifting drive assembly 32, providing a stable support structure for the lifting drive assembly 32. This makes the lifting drive assembly 32 more stable during the process of lifting the lifting plate 33, improving processing accuracy and reducing the impact of the lifting plate 33's shaking on the cutting or welding effect. The operating platform 1 is used to fix the lifting bracket 31 and the pipe moving device 2, providing stable support for them.

[0021] The tube transfer device 2 is used to move the heat pipe workpiece so that it passes through the cutting device 4 and the welding device 5 in sequence; while the lifting drive assembly 32 is used to drive the lifting plate 33 to move along the Z-axis, which can drive the cutting device 4 and the welding device 5 to approach the heat pipe workpiece. Through the cooperation of the tube transfer device 2 and the lifting drive assembly 32, the cutting device 4 or the welding device 5 can perform cutting or welding operations on the heat pipe workpiece.

[0022] After liquid injection and vacuuming, the heat pipe workpiece is sealed by a sealing device to ensure the vacuum level inside. The sealing device achieves the seal by flattening the opening of the heat pipe workpiece, forming a straight seal. However, this seal leaves an excess of copper tubing. This sealed area is a relatively vulnerable part of the heat pipe workpiece. Retaining this excess copper tubing makes it susceptible to bending during handling or vibration, creating a new stress concentration point. This could lead to fatigue cracking of the copper tubing from its root, causing leaks in the heat pipe workpiece.

[0023] The cutting device 4 can remove excess copper tubing, eliminating potential quality and reliability issues and ensuring product dimensional accuracy and consistency. The welding device 5 can weld the cut-off areas of the heat pipe workpiece, further ensuring the vacuum level inside the workpiece and preventing leaks.

[0024] The copper tube cutting and welding mechanism for heat-conducting tubes is equipped with a tube-moving device 2, a lifting device 3, a cutting device 4, and a welding device 5. The tube-moving device 2 drives the heat-conducting tube workpiece to move along the Y-axis, so that the heat-conducting tube workpiece passes through the cutting device 4 and the welding device 5 in sequence, realizing the precise positioning and stable transmission of the heat-conducting tube workpiece, reducing the positioning deviation caused by human operation error, and ensuring processing accuracy and consistency.

[0025] Specifically, the cutting device 4 includes a first mounting base 41, a second mounting base 42, a connecting base 43, a first fixed-length driving member 44, a second fixed-length driving member 45, a cutting driving member 46, a first fixed-length clamping block 47, a second fixed-length clamping block 48, and a cutting assembly. The first mounting base 41 and the second mounting base 42 are respectively disposed on the lifting plate 33. One end of the connecting base 43 is connected to the first mounting base 41, and the other end of the connecting base 43 is connected to the second mounting base 42. The connecting base 43 is provided with a receiving space, and a guide groove 431 is provided in the receiving space. The guide groove 431 is arranged along the X-axis direction. The first fixed-length clamping block 47 and the second fixed-length clamping block 48 are both slidably assembled in the guide groove 431. The first fixed-length drive component 44 and the cutting drive component 46 are mounted on the first mounting base 41, and the driving end of the first fixed-length drive component 44 is connected to one end of the first fixed-length clamping block 47; the second fixed-length drive component 45 is mounted on the second mounting base 42, and the driving end of the second fixed-length drive component 45 is connected to one end of the second fixed-length clamping block 48; the other end of the first fixed-length clamping block 47 and the other end of the second fixed-length clamping block 48 cooperate to form a copper tube fixed-length station, and the top surfaces of the first fixed-length clamping block 47 and the second fixed-length clamping block 48 are flush; the bottom of the guide groove 431 is provided with a through hole 432; the bottom of the connecting base 43 is provided with a clearance hole 433 communicating with the through hole 432. The cutting drive 46 is located above the first fixed-length drive 44, the upper end of the cutting assembly is connected to the driving end of the cutting drive 46, and the lower end of the cutting assembly is close to the top of the first fixed-length clamping block 47.

[0026] When the tube transfer mechanism moves the heat pipe workpiece below the cutting device 4, the lifting drive assembly 32 drives the lifting plate 33 to move downward, so that the heat pipe workpiece passes through the clearance hole 433 and the through hole 432 in sequence and enters the copper tube fixed length station. Subsequently, the first fixed length drive 44 drives the first fixed length clamp 47 to move to the accommodating space side, and at the same time, the second fixed length drive 45 drives the second fixed length clamp 48 to move to the accommodating space side to clamp the straight end of the heat pipe workpiece. Subsequently, the cutting drive 46 drives the cutting assembly to move to the second mounting base 42 side. Since the lower end of the cutting assembly is close to the first fixed length clamp 47, and the top surfaces of the first fixed length clamp 47 and the second fixed length clamp 48 are flush, and the material of the heat pipe workpiece is copper, when the cutting assembly moves to the second fixed length clamp 48, the lower end of the cutting assembly, together with the first fixed length clamp 47 and the second fixed length clamp 48, cuts off the excess part of the heat pipe workpiece.

[0027] The first fixed-length clamping block 47 and the second fixed-length clamping block 48 simultaneously clamp the heat-conducting pipe workpiece from both sides, providing uniform and stable clamping force and a solid support for subsequent cutting, preventing the heat-conducting pipe workpiece from moving during cutting. The cutting drive component 46 is arranged above the first fixed-length drive component 44, making reasonable use of space and making the structure more compact.

[0028] Specifically, the cutting assembly includes a transmission arm 491, a transmission slider 492, and a cutting block 493; the side wall of the accommodating space is provided with a transmission groove 494 along the X-axis direction; the upper end of the transmission arm 491 is connected to the driving end of the cutting drive 46, the lower end of the transmission arm 491 is connected to the transmission slider 492, the two ends of the transmission slider 492 are respectively connected to the transmission groove 494 on the corresponding side, the transmission slider 492 is connected to the cutting block 493, and the bottom of the cutting block 493 is in close contact with the top of the first fixed-length clamping block 47.

[0029] The cutting drive 46 drives the transmission slider 492 and the cutting block 493 to move via the transmission arm 491. The transmission slider 492 is used to limit the movement direction of the cutting block 493, preventing it from moving in other directions. The bottom of the cutting block 493 is in close contact with the top of the first fixed-length clamping block 47. The cutting drive 46 drives the cutting block 493 to move along the X-axis, so that the bottom of the cutting block 493 moves from the top of the first fixed-length clamping block 47 to the top of the first fixed-length clamping block 47, thereby achieving the purpose of cutting off the heat-conducting pipe workpiece.

[0030] Preferably, the bottom of the other end of the first fixed-length clamping block 47 and the bottom of the other end of the second fixed-length clamping block 48 are provided with fixed-length notches, and the two fixed-length notches cooperate to form a copper tube clamping channel 470. The top of the other end of the second fixed-length clamping block 48 is provided with a U-shaped cavity, and the top of the other end of the first fixed-length clamping block 47 is provided with a clamping extension protrusion 471 that matches the shape of the U-shaped cavity.

[0031] By tightening the extension protrusion 471 and the U-shaped cavity, the straight seal can be pressed into a U-shaped seal. The U-shaped structure disperses the pressure stress, reduces the risk of local deformation and cracking, and the elastic deformation capacity of the U-shape can absorb some vibration energy, reduce the probability of fatigue leakage, and improve the sealing performance and mechanical strength of the heat pipe workpiece.

[0032] Specifically, the welding device 5 includes a welding fixing plate 51 and a welding torch 52; the welding fixing plate 51 is fixed to the lifting bracket 31, and the welding torch 52 is fixed to the welding fixing plate 51, so that the welding torch 52 is suspended above the pipe moving device 2.

[0033] The welding fixing plate 51 is used to fix the welding torch 52, preventing the welding torch 52 from moving and ensuring the stability and consistency of welding quality. The welding torch 52 can refer to existing argon arc welding torches and is used in conjunction with the tube moving device 2 to realize the welding process.

[0034] Furthermore, the tube transfer device 2 includes a tube transfer sliding plate 21, a tube transfer slide rail 22, a tube transfer sliding block 23, a copper tube support frame 24, a tube clamping assembly 25, a sliding plate transmission rod 26, and a tube transfer driving component 27; The tube transfer slide rail 22 is disposed on the operating platform 1 along the Y-axis direction; the tube transfer sliding block 23 is disposed on the bottom surface of the tube transfer sliding plate 21; the tube transfer sliding block 23 is slidably connected to the tube transfer slide rail 22; the copper tube support frame 24 is mounted on the tube transfer sliding plate 21 along the Y-axis direction, and the length of the copper tube support frame 24 is greater than the maximum translational length of the tube transfer sliding plate 21; the tube clamping assembly 25 is disposed on the top surface of the tube transfer sliding plate 21. The operating platform 1 is provided with a tube-moving clearance notch 10. The tube-moving drive component 27 is disposed on the bottom surface of the operating platform 1. The drive end of the tube-moving drive component 27 is connected to the lower end of the sliding plate transmission rod 26, and the upper end of the sliding plate transmission rod 26 is connected to the tube-moving sliding plate 21.

[0035] The pipe-transfer driving component 27 is a cylinder, which drives the pipe-transfer sliding plate 21 to move along the Y-axis direction via the sliding plate transmission rod 26. The pipe-transfer driving component 27 is located on the bottom surface of the pipe-transfer sliding plate 21 and is driven by the sliding plate transmission rod 26, reducing the overall volume of the pipe-transfer device 2 and effectively improving space utilization. The pipe-transfer slide rail 22 and the pipe-transfer sliding block 23 prevent the pipe-transfer sliding plate 21 from moving in other directions, improving the conveying accuracy of the pipe-transfer device 2 and preventing situations where the heat-conducting pipe workpiece cannot be aligned with the through hole 432 or the welding torch 52.

[0036] The clamping assembly 25 is used to clamp the heat-conducting pipe workpiece, while the copper pipe support frame 24 serves to support and hold it. During the length setting process, the copper pipe support frame 24 can cooperate with the first length-setting clamping block 47 and the second length-setting clamping block 48 to fix the heat-conducting pipe workpiece. During the welding process, the copper pipe support frame 24 presses against the heat-conducting pipe workpiece, providing support for it, so that the welding torch 52 can weld the heat-conducting pipe workpiece. The length of the copper pipe support frame 24 is greater than the maximum translation length of the pipe-moving sliding plate, ensuring that the heat-conducting pipe workpiece will never leave the range of the copper pipe support frame 24.

[0037] The above structure enables the heat pipe workpiece to be transported smoothly, ensuring that the heat pipe workpiece can be accurately transported below the through hole 432 or the welding torch 52.

[0038] Furthermore, the tube clamping assembly 25 includes two tube clamping units, one of which is disposed on one side of the copper tube support frame 24, and the other of which is disposed on the other side of the copper tube support frame 24; the tube clamping unit includes a clamping plate 251, a tube clamping drive component 252, a plurality of tube clamping slide rails 253, a plurality of tube clamping sliders 254, and a plurality of tube clamping strips 255; The tube clamping drive component 252 and the tube clamping slide rail 253 are respectively disposed on the tube moving sliding plate 21. A plurality of tube clamping slide rails 253 are spaced apart and are arranged along the X-axis direction. A plurality of tube clamping sliders 254 are spaced apart at the bottom of the clamping plate 251. The position and number of the tube clamping sliders 254 are adapted to the position and number of the tube clamping slide rails 253. The tube clamping sliders 254 are slidably assembled with the tube clamping slide rails 253 corresponding to their positions. The driving end of the clamping drive 252 is connected to the clamping plate 251. Several clamping strips 255 are spaced apart on one side wall of the clamping plate 251 facing the copper tube support frame 24. One end of the clamping strip 255 is connected to the clamping plate 251, and the other end of the clamping strip 255 is provided with a clamping groove. The clamping strips 255 of the clamping units on both sides are arranged opposite to each other, and the clamping grooves of the oppositely arranged clamping strips 255 cooperate to form a copper tube clamping station. The bottom surface of the clamping strip 255 is higher than the top surface of the copper tube support frame 24.

[0039] The clamping grooves cooperate to form a copper tube clamping station. When it is necessary to clamp the heat pipe workpiece, the clamping drive components 252 on both sides drive the clamping plates 251 to move to one side of the copper tube support frame 24, so that the clamping strips 255 on both sides are tightly pressed together, and the clamping grooves cooperate to form a copper tube clamping station, so as to achieve the purpose of clamping the heat pipe workpiece.

[0040] In one specific embodiment of this utility model, the clamping drive component 252 is a cylinder, and the clamping unit includes two clamping slide rails 253 and two clamping sliders 254. One clamping slide rail 253 is located at the upstream end of the clamping drive component 252, and the other clamping slide rail 253 is located at the downstream end of the clamping drive component 252. The position of the clamping sliders 254 is adapted to the clamping slide rails 253. This structure prevents the clamping plate 251 from moving in other directions, making the movement of the clamping plate 251 more stable, thereby allowing the relatively arranged clamping grooves to cooperate in clamping the heat-conducting pipe workpiece.

[0041] Specifically, the lifting drive assembly 32 includes a lifting drive component 321, a synchronous belt 322, a transmission wheel 323, a lifting screw 324, and a guide rod 325; the lifting bracket 31 has lifting screws 324 on both sides in the conveying direction, the lower end of the lifting screw 324 is rotatably mounted on the operating platform 1, and the upper end of the lifting screw 324 passes through the lifting bracket 31 and is equipped with the transmission wheel 323; the lifting drive component 321 is located on the top of the operating platform 1, and the synchronous belt 322 is sleeved on the driving end of the lifting drive component 321 and the outer periphery of the transmission wheel 323; The lifting plate 33 is provided with transmission blocks 326 at both ends, and the transmission blocks 326 are threadedly connected to the lifting screw 324 on the corresponding side. Guide rods 325 are provided on both sides of the conveying direction of the lifting bracket 31, and the two ends of the lifting plate 33 are slidably connected to the guide rods 325 on the corresponding side.

[0042] With the above structure, screw drive is achieved through the cooperation of lifting screw 324 and transmission block 326, thereby driving the lifting plate 33 to move along the Z-axis. The lifting drive component 321 is a motor, which drives the lifting screws 324 on both sides to rotate through synchronous belt 322, thereby enabling the two ends of the lifting plate 33 to lift synchronously. Lifting screws 324 are respectively provided on both sides of the conveying direction of the lifting bracket 31, which can reduce the swaying of the lifting plate 33 during movement.

[0043] The guide rod 325 serves to limit the direction of movement of the lifting bracket 31, making the lifting plate 33 more stable during movement.

[0044] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
