Description

Technical Field

[0001] This invention relates to the field of welding machine technology, specifically to a welding machine for producing high-reliability, high-load-bearing drill pipe springs. Background Technology

[0002] In the exploration and extraction of resources such as oil and natural gas, drill pipe springs play a crucial role. Drill pipes must withstand extremely complex and harsh working environments during drilling, including immense axial pressure, frequent vibration and impact, high temperature and pressure, and corrosive media. With the continuous increase in drilling depth and the ever-increasing demands for drilling efficiency and safety, higher standards are being placed on the performance of drill pipe springs. Traditional drill pipe spring manufacturing processes and related welding equipment are gradually revealing numerous limitations.

[0003] Patent CN215824627U discloses a welding machine for producing pneumatic valve springs. The machine includes a base body, a clamping mechanism, a connecting assembly, and a top assembly. The clamping mechanism is fixedly connected to the top of the base body, and the top assembly is fixedly mounted on the top of the base body via two connecting assemblies. Each connecting assembly includes a fixing plate, and a hydraulic cylinder is fixedly mounted on the bottom of the fixing plate. This device, through the cooperation of the base body, clamping mechanism, connecting assembly, and top assembly, realizes a welding machine for producing pneumatic valve springs, greatly improving the protective effect of the welding machine and effectively preventing welding sparks from flying everywhere. The device can purify welding fumes, protecting workers and ensuring high safety. The top component is easily detachable from the base, facilitating maintenance and repair of components inside the welding machine. Furthermore, the purification filter is easy to replace, reducing the workload of workers. However, during the spring clamping process, the straight clamping plate makes it prone to spring detachment during welding, hindering effective fixation and support. Therefore, a high-reliability, high-load-bearing welding machine for drill pipe spring production is proposed to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a welding machine for producing high-reliability, high-load-bearing drill pipe springs, addressing the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a welding machine for producing high-reliability, high-load-bearing drill pipe springs, comprising a welding table, a baffle fixedly connected to the top of the welding table, a clamping device provided on the top of the welding table, a discharge device provided on the inner wall of the clamping device, a collecting device provided at the bottom of the welding table, and a welder installed at the bottom of the baffle; the clamping device includes a side plate, a support plate, a motor, a bidirectional threaded rod, a sliding plate, a sliding rod, an arc-shaped plate, a fixed rod, a V-shaped telescopic plate, a fixed plate, a fixed frame, an L-shaped plate, and an inner clamping plate; the side plate is fixedly connected to the top of the welding table, the support plate is fixedly connected to the right side of the side plate, the motor is fixedly connected to the top of the welding table, the bidirectional threaded rod is fixedly connected to the output end of the motor, the sliding plate is threadedly connected to the circumferential surface of the bidirectional threaded rod, the sliding rod is slidably connected to the inner wall of the side plate, the arc-shaped plate is fixedly connected to the right side of the sliding rod, the fixed rod is fixedly connected to the bottom of the support plate, and the V-shaped telescopic plate is rotatably connected to the circumference of the fixed rod by a torsion spring. The fixed plate is fixedly connected to the right side of the side plate, the fixed bracket is fixedly connected to the bottom of the fixed plate, the L-shaped plate is fixedly connected to the bottom of the arc plate, the inner clamping plate is rotatably connected to the top of the V-shaped telescopic plate, the top of the support plate is in contact with the bottom of the arc plate, the surface of the fixed plate is in contact with the inner wall of the arc plate, the top of the fixed plate is in contact with the bottom of the inner clamping plate, and the inner wall of the sliding plate is fixedly connected to the circumferential surface of the sliding rod. When welding the spring begins, the drill rod spring is placed on the top of the fixed plate, and the sliding rod moves, causing the arc plate to move, thereby clamping the surface of the drill rod spring. This reduces the pressure of the fixed plate during welding, thus improving the stability of the drill rod spring during welding. The inner arc surface of the arc plate can also wrap around the surface of the spring, further improving the stability of the device. The rotation of the V-shaped telescopic plate causes the inner clamping plate to move, thereby clamping and fixing the inner wall of the drill rod spring, thus increasing the firmness of the drill rod spring during welding.

[0006] Preferably, the discharge device includes a connecting plate, a sliding plate, an inclined plate, an inclined plate, and a telescopic rod. The connecting plate is fixedly connected to the rear of the L-shaped plate, the sliding plate is fixedly connected to the top of the connecting plate, the inclined plate is fixedly connected to the rear of the connecting plate, the inclined plate is slidably connected to the inner wall of the fixed frame, and the telescopic rod is rotatably connected to the inner wall of the inclined plate. The discharge device also includes an auxiliary plate, a lifting block, and an I-beam. The auxiliary plate is fixedly connected to the left side of the telescopic rod, the lifting block is slidably connected to the inner wall of the inclined plate, and the I-beam is fixedly connected to the top of the lifting block. The inner wall of the sliding plate two is threadedly connected to the circumferential surface of the bidirectional threaded rod. The top of the inclined plate one and the bottom of the inclined plate two are in contact with each other. When welding is completed, the inclined plate two moves, causing the I-plate to move, thereby pushing out the drill rod spring placed on the top of the I-plate. This makes it easier for workers to remove the welded drill rod spring, thereby improving the welding efficiency of the drill rod spring. At the same time, when the drill rod spring is placed in the welding area, the telescopic rod rotates, causing the auxiliary plate to rotate, thereby providing auxiliary limit on the circumferential surface of the drill rod spring and avoiding instability during the process of pushing the drill rod spring out.

[0007] Preferably, the collecting device includes a rotating rod, a vibrating plate, a protrusion, and a collecting box. The rotating rod is fixedly connected to the inner wall of the welding table. The vibrating plate is rotatably connected to the circumferential surface of the rotating rod via a torsion spring. The protrusion is fixedly connected to the bottom of the vibrating plate. The collecting box is fixedly connected to the bottom of the welding table. The collecting device also includes a second connecting plate, a top plate, and a cleaning plate. The second connecting plate is fixedly connected to the rear of the first inclined plate. The top plate is fixedly connected to the top of the second connecting plate. The cleaning plate is fixedly connected to the bottom of the second connecting plate. The bottom of the protrusion and the top of the top plate are mutually... The inner wall of the collection box contacts the bottom of the cleaning plate. When the drill rod spring is pushed out, the protrusion falls and drives the shaking plate to fall. The multiple protrusions cause the shaking plate to vibrate back and forth, which can shake off the welding slag that falls on the surface of the shaking plate, improving the cleaning effect of welding slag after welding. At the same time, the movement of the connecting plate drives the cleaning plate to move, which can scrape off the welding slag that falls into the collection box and adheres to it, avoiding the welding slag from adhering to and accumulating on the inner wall of the collection box for a long time, which would make it impossible to clean the welding slag on the inner wall of the collection box after too long.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This high-reliability, high-load-bearing welding machine for producing drill pipe springs utilizes the coordinated operation of a welding table, baffle, side plate, support plate, motor, bidirectional threaded rod, sliding plate, sliding rod, arc plate, fixed rod, V-shaped telescopic plate, fixed plate, fixed frame, L-shaped plate, and inner clamping plate. When welding begins, the drill pipe spring is placed on top of the fixed plate. The sliding rod moves, causing the arc plate to move, thus clamping the surface of the drill pipe spring. This reduces the pressure on the fixed plate during welding, improving the stability of the drill pipe spring during the welding process. The inner arc of the arc plate further enhances the stability of the device by wrapping the surface of the spring. Simultaneously, the rotation of the V-shaped telescopic plate moves the inner clamping plate, clamping and fixing the inner wall of the drill pipe spring, thereby increasing the strength of the drill pipe spring during welding.

[0010] 2. This high-reliability, high-load-bearing welding machine for producing drill rod springs works in coordination with connecting plate one, sliding plate two, inclined plate one, inclined plate two, telescopic rod, auxiliary plate, lifting block, and I-beam. Upon completion of welding, inclined plate two moves, causing the I-beam to move, thus ejecting the drill rod spring placed on top of the I-beam. This facilitates the removal of the welded drill rod spring by workers, improving welding efficiency. Simultaneously, when the drill rod spring is placed in the welding area, the telescopic rod rotates, causing the auxiliary plate to rotate, thus providing auxiliary limiting on the circumference of the drill rod spring and preventing instability during the ejection process.

[0011] 3. This high-reliability, high-load-bearing welding machine for producing drill pipe springs works in coordination with a rotating rod, a vibrating plate, protrusions, a collection box, a connecting plate II, a top plate, and a cleaning plate. When the drill pipe spring is pushed out, the protrusions fall and drive the vibrating plate to fall as well. This causes the vibrating plate to vibrate back and forth through multiple protrusions, which shakes off the welding slag that falls onto the surface of the vibrating plate, improving the cleaning effect of welding slag after welding. At the same time, the movement of the connecting plate II drives the cleaning plate to move, which scrapes off the residual welding slag that falls into the collection box and adheres to it. This prevents welding slag from adhering to and accumulating on the inner wall of the collection box for a long time, which would make it impossible to clean the welding slag on the inner wall of the collection box after a long period of time.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-8One embodiment of the present invention is as follows: a welding machine for producing high-reliability, high-load-bearing drill pipe springs, comprising a welding table 1, a baffle 2 fixedly connected to the top of the welding table 1, a clamping device 3 provided on the top of the welding table 1, a discharge device 4 provided on the inner wall of the clamping device 3, a collecting device 5 provided at the bottom of the welding table 1, and a welder 6 installed at the bottom of the baffle 2; the clamping device 3 includes a side plate 31, a support plate 32, a motor 33, a bidirectional threaded rod 34, a sliding plate 35, a sliding rod 36, an arc-shaped plate 37, a fixing rod 38, a V-shaped telescopic plate 39, a fixing plate 310, a fixing frame 311, an L-shaped plate 312, and an inner clamping plate 313, the side plate 31 being fixedly connected to the top of the welding table 1. The support plate 32 is fixedly connected to the right side of the side plate 31. The motor 33 is fixedly connected to the top of the welding table 1. The bidirectional threaded rod 34 is fixedly connected to the output end of the motor 33. The sliding plate 35 is threadedly connected to the circumferential surface of the bidirectional threaded rod 34. The sliding rod 36 is slidably connected to the inner wall of the side plate 31. The arc-shaped plate 37 is fixedly connected to the right side of the sliding rod 36. When welding the spring begins, the drill rod spring is placed on the top of the fixed plate 310. At this time, the motor 33 starts, which drives the bidirectional threaded rod 34 to rotate. The rotation of the bidirectional threaded rod 34 drives the sliding plate 35 to move. The movement of the sliding plate 35 drives the sliding rod 36 to move. The movement of the sliding rod 36 drives the arc-shaped plate 37 to move. The movement allows for clamping of the drill rod spring surface, reducing pressure on the fixing plate 310 during welding and improving its stability. The inner arc of the arc plate 37 further enhances stability by wrapping the spring surface. The fixing rod 38 is fixedly connected to the bottom of the support plate 32, and the V-shaped telescopic plate 39 is rotatably connected to the circumference of the fixing rod 38 via a torsion spring. The fixing plate 310 is fixedly connected to the right side of the side plate 31, and the fixing bracket 311 is fixedly connected to the bottom of the fixing plate 310. The L-shaped plate 312 is fixedly connected to the bottom of the arc plate 37, and the inner clamping plate 313 is rotatably connected to the V-shaped telescopic plate 310. The top of the shrink plate 39, the top of the support plate 32, and the bottom of the arc plate 37 are in contact with each other. The surface of the fixing plate 310 is in contact with the inner wall of the arc plate 37. The top of the fixing plate 310 is in contact with the bottom of the inner clamping plate 313. The inner wall of the sliding plate 35 is fixedly connected to the circumferential surface of the sliding rod 36. At the same time, the movement of the arc plate 37 drives the movement of the L-shaped plate 312. During the movement of the L-shaped plate 312, it will contact the lower left side of the V-shaped telescopic plate 39, so that the V-shaped telescopic plate 39 can be pushed to rotate. The rotation of the V-shaped telescopic plate 39 drives the inner clamping plate 313 to move, thereby clamping and fixing the inner wall of the drill rod spring, which can increase the firmness of the drill rod spring during the welding process.

[0023] The discharge device 4 includes a connecting plate 41, a sliding plate 42, an inclined plate 43, an inclined plate 44, and a telescopic rod 45. The connecting plate 41 is fixedly connected to the rear of the L-shaped plate 312, the sliding plate 42 is fixedly connected to the top of the connecting plate 41, the inclined plate 43 is fixedly connected to the rear of the connecting plate 41, and the inclined plate 44 is slidably connected to the inner wall of the fixed frame 311. When welding is completed, the motor 33 reverses to drive the arc plate 37 to move, the arc plate 37 moves to drive the L-shaped plate 312 to move, the L-shaped plate 312 moves to drive the connecting plate 41 to move, and the connecting plate 41 moves to drive the inclined plate 43 to move. When the inclined plate 43 moves, it will exert a squeezing force on the inclined plate 44, which will push the inclined plate 44 to move. The movement of the inclined plate 44 will drive the I-beam plate 48 to move, thereby pushing out the drill rod spring placed on top of the I-beam plate 48. This allows workers to easily remove the welded drill rod spring, thereby improving efficiency. The welding efficiency of the drill rod spring is improved by the rotatable connection of the telescopic rod 45 to the inner wall of the inclined plate 44, and the discharge device 4 also includes an auxiliary plate 46, a lifting block 47, and an I-beam 48. The auxiliary plate 46 is fixedly connected to the left side of the telescopic rod 45, the lifting block 47 is slidably connected to the inner wall of the inclined plate 44, and the I-beam 48 is fixedly connected to the top of the lifting block 47. The inner wall of the sliding plate 42 is threadedly connected to the circumferential surface of the bidirectional threaded rod 34. The top of the inclined plate 43 and the bottom of the inclined plate 44 are in contact with each other. When the drill rod spring is placed in the welding area, the drill rod spring will apply pressure to the I-beam 48 through gravity, forcing the I-beam 48 to move downward. The movement of the I-beam 48 drives the lifting block 47 to move, the movement of the lifting block 47 drives the telescopic rod 45 to move and rotate, and the rotation of the telescopic rod 45 drives the auxiliary plate 46 to rotate. This can help limit the circumferential surface of the drill rod spring and avoid instability during the process of pushing the drill rod spring out.

[0024] Working principle: When welding the spring begins, the drill rod spring is placed on top of the fixed plate 310. At this time, the motor 33 starts, driving the bidirectional threaded rod 34 to rotate. The rotation of the bidirectional threaded rod 34 drives the sliding plate 35 to move, which in turn drives the sliding rod 36 to move. The sliding rod 36 then drives the arc plate 37 to move, thereby clamping the surface of the drill rod spring. This reduces the pressure on the fixed plate 310 during welding, thus improving the stability of the drill rod spring during welding. The inner arc surface of the arc plate 37 also wraps around the surface of the spring, further improving the stability of the device. Simultaneously, the movement of the arc plate 37 drives the L-shaped plate 312 to move. During the movement of the L-shaped plate 312, it contacts the lower left side of the V-shaped telescopic plate 39, causing the V-shaped telescopic plate 39 to rotate. The rotation of the V-shaped telescopic plate 39 drives the inner clamping plate 313 to move, thereby clamping and fixing the inner wall of the drill rod spring, thus increasing the firmness of the drill rod spring during welding.

[0025] Upon completion of welding, motor 33 reverses direction, causing arc-shaped plate 37 to move. The movement of arc-shaped plate 37 then moves L-shaped plate 312, which in turn moves connecting plate 41. Connecting plate 41 then moves inclined plate 43. As inclined plate 43 moves, it exerts pressure on inclined plate 44, causing it to push inclined plate 44 to move. The movement of inclined plate 44 then moves I-beam 48, which in turn pushes out the drill rod spring placed on top of I-beam 48, facilitating the removal of the welded part from the work area. Removing the drill rod spring improves welding efficiency. When the drill rod spring is placed in the welding area, it applies pressure to the I-beam 48 under gravity, forcing it to move downwards. This movement of the I-beam 48 moves the lifting block 47, which in turn moves and rotates the telescopic rod 45. The rotation of the telescopic rod 45 then rotates the auxiliary plate 46, thus providing auxiliary limiting for the circumference of the drill rod spring and preventing instability during its ejection.

[0026] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the collecting device 5 includes a rotating rod 51, a vibrating plate 52, a protrusion 53, and a collecting box 54. The rotating rod 51 is fixedly connected to the inner wall of the welding table 1. The vibrating plate 52 is rotatably connected to the circumferential surface of the rotating rod 51 via a torsion spring. The protrusion 53 is fixedly connected to the bottom of the vibrating plate 52. The collecting box 54 is fixedly connected to the bottom of the welding table 1. The collecting device 5 also includes a second connecting plate 55, a top plate 56, and a cleaning plate 57. The second connecting plate 55 is fixedly connected to the rear of the first inclined plate 43, and the top plate 56 is fixedly connected to the top of the second connecting plate 55. When the drill rod spring is pushed out, the first inclined plate 43 moves, causing the second connecting plate 55 to move. The movement of the second connecting plate 55 causes the top plate 56 to move. During the movement of the top plate 56, it will contact the protrusion 53, causing the top plate 56 to push the protrusion 53 away from the weld. When block 53 is lifted, the protrusion 53 lifts the shaking plate 52. When the top plate 56 passes the protrusion 53, the protrusion 53 falls and pulls the shaking plate 52 down. Thus, the shaking plate 52 can be made to shake back and forth through multiple protrusions 53, thereby shaking off the welding slag that falls on the surface of the shaking plate 52, improving the cleaning effect of welding slag after welding. The cleaning plate 57 is fixedly connected to the bottom of the connecting plate 2 55. The bottom of the protrusion 53 is in contact with the top of the top plate 56, and the inner wall of the collection box 54 is in contact with the bottom of the cleaning plate 57. At the same time, the movement of the connecting plate 2 55 drives the cleaning plate 57 to move, thereby scraping off the welding slag that falls into the collection box 54 and adheres to it. This prevents the welding slag from adhering to and accumulating on the inner wall of the collection box 54 for a long time, which would make it impossible to clean the welding slag on the inner wall of the collection box 54 after too long.

[0027] Working principle: When the drill rod spring is pushed out, the inclined plate 43 moves, driving the connecting plate 55 to move. The connecting plate 55 then drives the top plate 56 to move. During the movement of the top plate 56, it comes into contact with the protrusion 53, causing the top plate 56 to lift the protrusion 53. The lifting of the protrusion 53 lifts the vibrating plate 52. When the top plate 56 passes the protrusion 53, the protrusion 53 falls and drives the vibrating plate 52 to fall. Thus, the vibrating plate 52 can be vibrated back and forth by multiple protrusions 53, thereby shaking off the welding slag that falls on the surface of the vibrating plate 52, improving the cleaning effect of welding slag after welding. At the same time, the movement of the connecting plate 55 drives the cleaning plate 57 to move, thereby scraping off the residual welding slag that falls into the collection box 54, preventing the welding slag from adhering and accumulating on the inner wall of the collection box 54 for a long time, which would make it impossible to clean the welding slag on the inner wall of the collection box 54 after too long.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
