Description

Technical Field

[0001] This invention relates to the field of wire rod welding production technology, specifically a wire rod ring end welding device. Background Technology

[0002] Guy rods are mostly used to connect power transmission towers to ground anchors, serving a pulling and fixing function. The ring end is the end structure of the finished guy rod. The end of the rod needs to be bent out of the ring. To ensure the strength of the ring, a strip-shaped section to be welded needs to be reserved on the ring, and this strip-shaped section to be welded to the rod body of the guy rod, thereby increasing the welding area.

[0003] Currently, the processing of the guy wire rod ring end is mostly done manually in conjunction with simple machinery. First, the rod is manually bent to a certain length, and then moved to the welding station for welding. During the welding process, it is also necessary to ensure the shape of the ring end. The entire processing process requires multiple manual transfers, positioning, and adjustments. The processing flow is scattered, with a large amount of manpower and low processing efficiency. In addition, manual positioning and bending are prone to dimensional deviations, which affect the subsequent matching and installation of the ring and the tower connection parts. It is difficult to guarantee the processing accuracy consistently. Summary of the Invention

[0004] The purpose of this invention is to provide a welding device for the pull ring end of a pull bar, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A welding device for the pull ring end of a pull bar, comprising: 1. a base, wherein the base is connected to a control console, and further comprising: A rod conveying and pushing structure connected to a base, the rod conveying and pushing structure including a support mechanism connected to the base, the support mechanism being connected to a limit drive mechanism, the support mechanism being connected to a horizontal push mechanism, the limit drive mechanism being movably connected to the horizontal push mechanism, and a fixed length measuring mechanism connected to the base; An elbow structure is installed between the load-bearing mechanism and the fixed-length measuring mechanism. The elbow structure includes a mounting frame fixedly connected to a base, a motor base fixedly connected to the base, a first motor fixedly connected to the motor base, a rotating frame fixedly connected to the output shaft of the first motor, a straight groove on the rotating frame, a rotating support platform slidably connected to the straight groove, a drive rod detachably connected to the rotating support platform, a polygonal frame rotatably connected to the drive rod, a V-groove wheel bolted to the polygonal frame, a guide rail plate detachably connected to the mounting frame, a curved support shaft fixedly connected to the guide rail plate, a guide groove on the guide rail plate, a guide groove slidably connected to the drive rod, and an auxiliary pressure-bearing mechanism connected to the base. The welded structure that connects to the base; A finished product collection rack is fixedly connected to the base, and the finished product collection rack is located below the guide rail plate.

[0006] As a further improvement of the present invention: the support mechanism includes a support base fixedly connected to the base, the support base is rotatably connected to multiple sets of support rollers arranged in a straight line, the support base is connected to a limit drive mechanism, and the support base is connected to a horizontal push mechanism.

[0007] As a further improvement of the present invention: the limiting drive mechanism includes two sets of first active telescopic frames fixedly connected to the support base, and the two sets of first active telescopic frames are detachably connected to a lifting frame slidably connected to the support base. Multiple sets of grooved wheels arranged in a straight line are rotatably mounted on the lifting frame, wherein the two sets of grooved wheels at both ends are connected to a second motor. The second motor is fixedly connected to the lifting frame, and the lifting frame is movably connected to the horizontal pushing mechanism.

[0008] As a further improvement of the present invention: the horizontal pushing mechanism includes two sets of first electric telescopic rods fixedly connected to the support base, the moving ends of the two sets of first electric telescopic rods are jointly fixedly connected to a set of push frames, the push frames are movably connected to the lifting frame, and the push frames are slidably connected to the support base.

[0009] As a further improvement of the present invention: the fixed length measuring mechanism includes a first upright frame fixedly connected to the base, a second active telescopic frame fixedly connected to the first upright frame, a synchronization frame fixedly connected to the moving end of the second active telescopic frame, a pressure sensor fixedly installed at one end of the synchronization frame facing the support seat, a linear displacement sensor fixedly connected to the first upright frame, and the moving end of the linear displacement sensor fixedly connected to the synchronization frame.

[0010] As a further improvement of the present invention: the welding structure includes a second upright frame fixedly connected to the base, the second upright frame being fixedly connected to a third active telescopic frame, and the moving end of the third active telescopic frame being fixedly connected to a welding torch.

[0011] As a further improvement of the present invention: the guide groove is composed of a rotary groove and a transverse groove connected to each other, and the rotary groove is arranged coaxially with the curved support shaft.

[0012] As a further improvement of the present invention: the auxiliary support mechanism includes a third upright fixedly connected to the base, the third upright fixedly connected to a second electric telescopic rod, the moving end of the second electric telescopic rod fixedly connected to a support frame, and the support frame being disposed above the transverse groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In use, the rod to be processed is placed on the support mechanism. The limit drive mechanism presses on the rod and drives it to move towards the fixed length measuring mechanism. When the end of the rod contacts the fixed length measuring mechanism, the fixed length measuring mechanism completes the measurement of the rod's extension length. After reaching the set length, the limit drive mechanism stops driving the rod. During this process, the rod is engaged in the V-groove of the V-groove wheel and supported by the curved support shaft. After positioning, the first motor drives the rotating frame to rotate, which in turn drives the rotating support table and the drive rod to move. The drive rod moves along the guide groove of the guide rail plate, causing it to first rotate around the axis of the curved support shaft and then move linearly. During this process, the rotating support table slides relative to the rotating frame, and the polygonal frame rotates relative to the drive rod. The V-groove wheel, which rotates with the polygonal frame, presses against the end of the rod, driving the rod closer to the fixed length measuring mechanism. The part to be processed by the fixed mechanism bends along the curved surface of the curved support shaft, and the auxiliary support mechanism abuts against the rod. The linearly moving V-grooved wheel presses the remaining section to be processed onto the rod, thereby completing the bending and forming operation of the rod. This process forms a pull ring and a strip-shaped section to be welded to the rod. Subsequently, the welding structure moves and welds the strip-shaped welding end to the rod, so that the rod is welded into a finished pull bar. Then, as the rotating frame continues to rotate, the guide groove guides the drive rod to move laterally, the V-grooved wheel moves laterally and disengages from the finished pull bar, the limit drive mechanism releases the limit on the rod, and the horizontal pushing mechanism pushes the bent and welded finished pull bar towards the finished product collection rack, causing the finished pull bar to fall into the finished product collection rack for collection. The entire processing process is completed automatically, without the need for repeated manual positioning, bending, and welding, effectively improving the processing efficiency of the pull ring end of the pull bar. This invention automatically completes the forming, welding, and collection of rods by using a rod conveying and pushing structure, an elbow structure, a welding structure, and a finished product collection rack in a coordinated manner. The entire processing flow is continuous and automated, effectively improving the processing efficiency and accuracy of the pull bar ring end and saving manpower. Attached Figure Description

Detailed Implementation

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0025] Example 1, see Figures 1-9 As shown, a welding device for the pull ring end of a pull bar includes a base 1, wherein a control console 2 is connected to the base 1, and further includes: The rod conveying and pushing structure 3 is connected to the base 1. The rod conveying and pushing structure 3 includes a support mechanism 4 connected to the base 1. The support mechanism 4 is connected to a limit drive mechanism 5. The support mechanism 4 is connected to a horizontal push mechanism 6. The limit drive mechanism 5 is movably connected to the horizontal push mechanism 6. The base 1 is connected to a fixed length measuring mechanism 7. An elbow structure 8 is provided between the load-bearing mechanism 4 and the fixed-length measuring mechanism 7. The elbow structure 8 includes a mounting frame 9 fixedly connected to the base 1. The base 1 is fixedly connected to a motor base 10. The motor base 10 is fixedly connected to a first motor 11. The output shaft of the first motor 11 is fixedly connected to a rotating frame 12. The rotating frame 12 has a straight groove 13. The straight groove 13 is slidably connected to a rotating support platform 14. The rotating support platform 14 is detachably connected to a drive rod 15. The drive rod 15 is rotatably connected to a polygonal frame 16. The polygonal frame 16 is bolted to a V-groove wheel 17. The mounting frame 9 is detachably connected to a guide rail plate 18. The guide rail plate 18 is fixedly connected to a curved support shaft 19. The guide rail plate 18 has a guide groove 20. The guide groove 20 is slidably connected to the drive rod 15. The base 1 is connected to an auxiliary support mechanism 21. Welded structure 22 connected to base 1; The finished product collection rack 23 is fixedly connected to the base 1 and is located below the guide rail plate 18.

[0026] In use, the rod to be processed is placed on the support mechanism 4. The limiting drive mechanism 5 presses on the rod and drives the rod to move towards the fixed length measuring mechanism 7. When the end of the rod contacts the fixed length measuring mechanism 7, the fixed length measuring mechanism 7 completes the measurement of the rod's extension length. After the set length is reached, the limiting drive mechanism 5 stops driving the rod. During this period, the rod is inserted into the V-groove of the V-groove wheel 17 and supported by the curved support shaft 19. After positioning is completed, the first motor 11 drives the rotating frame 12 to rotate. The rotating frame 12 drives the rotating support platform 14 and the drive rod 15 to move. The drive rod 15 moves along the guide groove 20 of the guide rail plate 18, so that the drive rod 15 first rotates around the axis of the curved support shaft 19, and then moves linearly. During this period, the rotating support platform 14 slides relative to the rotating frame 12, and the polygon frame 16 rotates relative to the drive rod 15. With the V-groove wheel 17 rotating with the polygon frame 16, the rod end is squeezed to achieve the desired extension length. The part of the drive rod to be processed approaches the fixed-length measuring mechanism 7 and bends along the curved surface of the curved support shaft 19. The auxiliary support mechanism 21 abuts against the rod, and the linearly moving V-grooved wheel 17 presses the remaining section to be processed onto the rod, thereby completing the bending and forming operation of the rod. This process forms a pull ring and a strip-shaped section to be welded to the rod. Subsequently, the welding structure 22 moves and welds the strip-shaped welding end to the rod, so that the rod is welded into a finished pull bar. Then, as the rotating frame 12 continues to rotate, the guide groove 20 guides the drive rod 15 to move laterally, the V-grooved wheel 17 moves laterally and disengages from the finished pull bar, the limiting drive mechanism 5 releases the limiting on the rod, and the horizontal pushing mechanism 6 pushes the bent and welded finished pull bar towards the finished product collection rack 23, so that the finished pull bar falls into the finished product collection rack 23 for collection. The entire processing process is completed automatically without the need for repeated manual positioning, bending, and welding, effectively improving the processing efficiency of the pull ring end of the pull bar. This invention automatically completes the forming, welding, and collection of rods by means of the cooperation of rod conveying and pushing structure 3, elbow structure 8, welding structure 22, and finished product collection rack 23. The entire processing flow is continuous and automated, which effectively improves the processing efficiency and accuracy of the pull bar pull ring end and saves manpower.

[0027] In one embodiment, the support mechanism 4 includes a support base 24 fixedly connected to the base 1. The support base 24 is rotatably connected to multiple sets of rollers 25 arranged in a straight line. The support base 24 is connected to a limiting drive mechanism 5 and a horizontal pushing mechanism 6. The multiple sets of rollers 25 provide support and guidance for the rod, facilitating linear movement of the rod along the linear direction of the rollers 25 under the drive of the limiting drive mechanism 5, thus facilitating the transport of the rod towards the fixed-length measuring mechanism 7.

[0028] In one embodiment, the limiting drive mechanism 5 includes two sets of first active telescopic frames 26 fixedly connected to the support base 24. The two sets of first active telescopic frames 26 are detachably connected to a lifting frame 27 slidably connected to the support base 24. Multiple sets of grooved wheels 28 arranged in a straight line are rotatably mounted on the lifting frame 27. The two sets of grooved wheels 28 at both ends are connected to a second motor 29. The second motor 29 is fixedly connected to the lifting frame 27. The lifting frame 27 is movably connected to the horizontal pushing mechanism 6. After the rod is placed on the support roller 25, the first active telescopic frame 26 drives the lifting frame 27 to move downward, so that multiple sets of grooved wheels 28 work together with the support roller 25 below to limit the rod. The grooved wheels 28 limit the rod axially. Then, the second motor 29 drives the grooved wheels 28 connected to it to rotate. The rotating grooved wheels 28 drive the rod to complete the conveying through friction. When the end of the rod contacts the length measuring mechanism 7 to complete the length measurement, the second motor 29 stops rotating, completing the length positioning operation of the rod. After the rod is processed into a finished pull bar, the first active telescopic frame 26 drives the lifting frame 27 to move upward, so that multiple sets of grooved wheels 28 disengage from the finished pull bar, providing space for the subsequent horizontal pushing mechanism 6 to push the finished pull bar.

[0029] In one embodiment, the horizontal pushing mechanism 6 includes two sets of first electric telescopic rods 30 fixedly connected to the support base 24. The moving ends of the two sets of first electric telescopic rods 30 are jointly fixedly connected to a pusher 31. The pusher 31 is movably connected to the lifting frame 27 and slidably connected to the support base 24. When the welding operation is completed and the V-groove wheel 17 and the grooved wheel 28 are both disengaged from the finished pull bar, the two sets of first electric telescopic rods 30 extend synchronously, driving the pusher 31 to move. The pusher 31 pushes the finished pull bar, causing the finished pull bar to disengage from the support roller 25 and the curved support shaft 19. Finally, the finished pull bar falls into the finished product collection rack 23 for collection.

[0030] In one embodiment, the fixed length measuring mechanism 7 includes a first upright 32 fixedly connected to the base 1, a second active telescopic frame 33 fixedly connected to the first upright 32, a synchronization frame 34 fixedly connected to the moving end of the second active telescopic frame 33, a pressure sensor 35 fixedly installed at one end of the synchronization frame 34 facing the support base 24, and a linear displacement sensor 36 fixedly connected to the first upright 32, the moving end of the linear displacement sensor 36 being fixedly connected to the synchronization frame 34. During the movement of the rod towards the pressure sensor 35, when the rod extends to the set value, the end of the rod just contacts the pressure sensor 35. When the pressure sensor 35 detects the pressure signal, the control console 2 acquires the signal and controls the limit drive mechanism 5 to immediately stop the conveying, completing the fixed-length positioning. After the fixed-length positioning is completed, the second active telescopic frame 33 can drive the synchronous frame 34 to retract, avoiding obstructing the bending of the rod. At the same time, if the length of the rod to be processed needs to be adjusted, the extension length of the second active telescopic frame 33 can be adjusted through the control console 2, and the linear displacement sensor 36 accurately measures the moving length of the synchronous frame 34 driven by the second active telescopic frame 33. As the second active telescopic frame 33 retracts, the preset length of the rod to be processed increases.

[0031] In one embodiment, the welding structure 22 includes a second upright 37 fixedly connected to the base 1. A third active telescopic frame 38 is fixedly connected to the second upright 37. A welding torch 39 is fixedly connected to the movable end of the third active telescopic frame 38. The welding torch 39 can be either an electric arc welding torch or a plasma arc welding torch. The third active telescopic frame 38 adjusts the position of the welding torch 39 by actively telescopicating. Then, the welding torch 39 starts to complete the welding operation. After welding is completed, the third active telescopic frame 38 drives the welding torch 39 to reset, waiting for the next welding operation.

[0032] In one embodiment, the guide groove 20 is formed by interconnecting a rotary groove 40 and a transverse groove 41. Both the rotary groove 40 and the transverse groove 41 provide movement guidance for the moving drive rod 15. The rotary groove 40 is coaxially arranged with the curved support shaft 19. When the drive rod 15 is in the rotary groove 40, the moving drive rod 15 rotates along the rotary groove 40 with the axis of the curved support shaft 19 as the center. With the compression of the rod by the V-groove wheel 17, the section of the rod to be processed is gradually bent and fitted to the outer curved surface of the curved support shaft 19, completing the initial bending and forming of the pull ring. When the drive rod 15 rotates to the position where the rotary groove 40 and the transverse groove 41 are connected, the moving drive rod 15 continues to move linearly along the transverse groove 41, so that the V-groove wheel 17 presses the remaining section to be processed onto the rod, providing stable pressing and positioning for subsequent welding operations and ensuring the accuracy of the welding position.

[0033] Example 2, based on Example 1, see [link / reference] Figure 1 and Figure 2The auxiliary support mechanism 21 includes a third upright 42 fixedly connected to the base 1. A second electric telescopic rod 43 is fixedly connected to the third upright 42. A support frame 44 is fixedly connected to the moving end of the second electric telescopic rod 43. The support frame 44 is positioned above the transverse groove 41. After the fixed-length positioning is completed, the second electric telescopic rod 43 drives the support frame 44 to move downward. The support frame 44 abuts against the rod, keeping the rod stable during bending and preventing it from shifting under bending force. This effectively improves the bending accuracy and ensures the accuracy of subsequent welding positions. After the bending and welding operation is completed, the second electric telescopic rod 43 drives the support frame 44 to move upward and reset, releasing the limit on the rod and facilitating the pushing and collection of the finished pull rod.

[0034] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
