Description

Technical Field

[0001] The present invention relates to the technical field of metal pipe welding, and particularly to an arc welding device for metal strip steel used in the processing of metal conduit pipes. Background Art

[0002] A metal conduit pipe is a pipe system used to protect electric wires and cables, and is usually applied in buildings, industrial facilities and electrical installations. It can not only protect the electric wires from physical damage, but also prevent the spread of fire to a certain extent, and helps to standardize the wire layout, making the wiring more neat and orderly. According to the material, it can be divided into galvanized steel pipes, stainless steel pipes, aluminum alloy pipes, etc., and the metal conduit pipe is formed by bending and welding metal plates.

[0003] Publication No. CN117444353B discloses an arc welding device and an arc welding method. The arc welding device includes a housing assembly, a driving assembly, two transmission clamping assemblies, two stabilizing assemblies and a welding assembly. It realizes the docking and fixation between two tubular workpieces to be welded, provides a stable working environment, and provides stable and efficient welding. At the same time, inert gas from the outside is introduced into the device to avoid the generation of oxidation, impurities and brittleness during welding, and the inert gas flow can take away the water vapor that may accumulate in the internal cavity of the tubular workpiece to be welded, preventing gas holes from being generated by water vapor during welding, resulting in non-dense welds and affecting the welding quality, and can provide effective cooling to avoid the large amount of heat generated by arc welding from causing the welding torch to burn out.

[0004] Although the above application and the prior art can reduce the impact force and vibration during the welding process, thereby protecting the welding torch and the welding area and improving the welding quality, when the device and the prior art weld the surface of the tubular workpiece to be welded, a welding wire needs to be used as the welding medium. When welding tubular workpieces to be welded with different specifications, one end of the welding wire will be aligned with the gap of the tubular workpiece to be welded, but there will be a height error between the other end of the welding wire and the gap of the tubular workpiece to be welded. As a result, the welding wire cannot fit with the gap of the tubular workpiece to be welded. Moreover, when adjusting the height of one end of the welding wire or pulling the welding wire, the welding wire will rotate on the material roller, causing the welding wire to gradually move at both ends of the material roller, and then resulting in the deviation of the welding wire from the gap of the tubular workpiece to be welded. To prevent this situation, an opening is usually provided at one end of the material box, which will cause the welding wire to wear against the opening, thereby affecting the subsequent welding effect. Moreover, after welding, the welding wire will adhere to the tubular workpiece to be welded, thereby affecting the welding effect of the tubular workpiece to be welded and the welding efficiency of other tubular workpieces to be welded. Therefore, we have proposed an arc welding device for metal strip steel used in the processing of metal conduit pipes. Summary of the Invention

When welding tubular workpieces to be welded with different specifications, one end of the welding wire will be aligned with the gap of the tubular workpiece to be welded, but there will be a height error between the other end of the welding wire and the gap of the tubular workpiece to be welded, affecting the subsequent welding effect. Moreover, when adjusting or pulling one end of the welding wire, the welding wire will rotate on the material roller, resulting in the deviation of the welding wire from the gap of the tubular workpiece to be welded, further affecting the subsequent welding effect. After welding, the welding wire will adhere to the tubular workpiece to be welded, affecting the welding effect of the tubular workpiece to be welded and the welding efficiency of other tubular workpieces to be welded.

[0016] (III) Beneficial effects Compared with the prior art, the present invention provides a metal strip steel arc welding device for metal threading pipe processing, which has the following beneficial effects: 1. For the metal strip arc welding device used in the processing of metal conduit pipes, by using the adjustment component, when the welding wire is pulled to one end of the metal conduit pipe, the second driving motor is started. The second driving motor drives the rotating bar to rotate through the first driving rod, so that the rotating bar drives the guiding roller to rotate, and then the surface of the guiding roller comes into contact with the surface of the welding wire.

For the metal strip arc welding device used in the processing of metal conduit pipes, by using the guiding component, during the pulling process of the welding wire, the welding wire gradually rotates at both ends of the material roller. When the welding wire is at one end of the material roller, the pulled welding wire rotates on the surface of the guiding roller. When the welding wire is continuously pulled, the welding wire moves to the surface of another guiding roller, thus avoiding the deviation of one end of the welding wire at the gap of the metal conduit pipe due to the continuous rotation of the material roller, which affects the welding quality, and achieving the effect of preventing deviation.

[0018] 3. For the metal strip arc welding device used in the processing of metal conduit pipes, by the combined use of the adjustment component and the cutting component, when the welding wire adheres to the metal conduit pipe, the driving motor and the second driving motor are started. The driving motor drives the cutting disc to rotate continuously, and the second driving motor drives the driving gear to rotate through the first driving rod. The driving gear drives the moving gear plate to move through the driven tooth plate, so that the moving gear plate drives the rotating rod to rotate through the driven gear. Then, the rotating rod drives the cutting disc to move upward through the rotating block and the fixed plate, so that the cutting disc cuts the adhesion part, thus avoiding the adhesion of the welding wire to the metal conduit pipe, and achieving the effect of preventing adhesion.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Specific Embodiment 1, please refer to Figures 1 to 4 , an arc welding device for metal strip steel used in the processing of metal conduit pipes, comprising: an operation box 1 and a welding assembly 11 arranged inside the operation box 1, a feeding box 2, fixedly connected to the top of the operation box 1, and one end of the feeding box 2 is fixedly communicated with one end of the operation box 1. A detection assembly 13 is arranged inside the operation box 1. Moving grooves 21 are respectively opened on both sides inside the feeding box 2. A moving block 22 is slidably connected inside the moving grooves 21. A turntable 221 is rotatably connected to the surface of the moving block 22. A wire reel 222 is fixedly connected to the surface of the turntable 221. A welding wire is arranged on the surface of the wire reel 222. A control panel 23 is arranged on the surface of the feeding box 2; a mounting plate 111, fixedly connected inside the operation box 1. A first driving motor 112 is fixedly connected to the top of the mounting plate 111. The output end of the first driving motor 112 is fixedly connected to a first screw rod 113. A screw block 114 is threadedly connected to the surface of the first screw rod 113. The bottom of the screw block 114 is fixedly connected to a welding box 115; an adjustment assembly 3, arranged on one side of the feeding box 2, for adjusting the welding wire inside the feeding box 2 to prevent one end of the welding wire from tilting during the stretching process; a guiding assembly 4, arranged inside the feeding box 2, to prevent the welding wire inside the feeding box 2 from shaking during the stretching process, thereby causing one end of the welding wire to shift after the stretching is completed; a cutting component 5, arranged inside the operation box 1, for cutting the welding wire to prevent the welding wire from adhering to the metal conduit pipe after welding; It should be noted that a lifting assembly is arranged inside the welding assembly 11. An arc welding gun is arranged at the bottom of the lifting assembly. The lifting assembly includes a driving cylinder fixedly connected inside the welding box 115. The output end of the driving cylinder is differentially connected to a telescopic rod. The bottom of the telescopic rod is fixedly connected to the top of the arc welding gun. A mechanical claw is arranged inside the operation box 1. The mechanical claw can clamp and move the welding wire up and down, so as to ensure that the welding wire can stay stably inside the metal conduit pipe. The mechanical claw belongs to the prior art and will not be elaborated here. A through groove is opened on the top of the mounting plate 111. The screw block 114 passes through the through groove and is slidably connected inside it; When arc welding is required for a metal conduit, one end of the welding wire is fixed by a mechanical jaw and then the welding wire is pulled to one end of the gap of the metal conduit. Subsequently, the lifting assembly is started, and the lifting assembly moves the arc welding gun to the top of the gap of the metal conduit. Then, the first driving motor 112 is started, and the first driving motor 112 drives the screw block 114 to move through the first screw rod 113, so that the screw block 114 drives the arc welding gun to gradually move through the welding box 115, thereby performing arc welding on the metal conduit; Specific Embodiment Two, please refer to Figures 1 to 6 , a metal strip arc welding device for processing metal conduits provided according to Specific Embodiment One, the present embodiment provides a further technical solution: The adjustment assembly 3 includes a second driving motor 31 fixedly connected inside the operation box 1. The output end of the second driving motor 31 is fixedly connected with a first driving rod 311. The surface of the first driving rod 311 is fixedly connected with a rotating bar 32. One end of the rotating bar 32 is rotatably connected with a guiding roller 321 inside; It should be noted that an annular guiding groove is formed on the surface of the guiding roller 321 for stably conveying the welding wire. When the welding wire on the surface of the mechanical jaw is pulled, the welding wire drives the guiding roller 321 to rotate through the annular guiding groove, so that the welding wire can be stably conveyed when being pulled; When it is necessary to adjust the height of one end of the welding wire, after the welding wire on the surface of the mechanical jaw is pulled to one end of the metal conduit, the second driving motor 31 is started. The second driving motor 31 drives the rotating bar 32 to rotate through the first driving rod 311, so that the rotating bar 32 drives the guiding roller 321 to rotate, and then the surface of the guiding roller 321 comes into contact with the surface of the welding wire. As the guiding roller 321 rotates, one end of the welding wire is aligned with the gap of the metal conduit, so as not to affect the welding quality of the subsequent welding assembly 11 on the metal conduit; Specific Embodiment Three, please refer to Figures 1 to 10 , a metal strip arc welding device for processing metal conduits provided according to Specific Embodiment Two, the present embodiment provides a further technical solution: The guiding assembly 4 includes a fixing block 41 fixedly connected inside the feeding box 2. A receiving groove 411 is formed inside the fixing block 41. An extension block 42 is slidably connected inside the receiving groove 411. One end of the extension block 42 is fixedly connected with two arc-shaped plates 422. Two guiding rollers 423 are rotatably connected inside the two arc-shaped plates 422. Springs 412 are fixedly connected at the four corners of the receiving groove 411. One end of the spring 412 is fixedly connected with the end of the extension block 42 away from the two arc-shaped plates 422. A wire guiding hole 421 is formed at the end of the extension block 42 close to the two arc-shaped plates 422; It should be noted that both the inside of the fixed block 41 and the extension block 42 are in a hollow state. A steering roller is rotatably connected inside the fixed block 41. The setting of the steering roller can effectively prevent the welding wire from contacting the feed box 2. An annular guiding groove is formed on the surface of the guiding roller 423. The setting of the annular guiding groove can prevent the welding wire from falling off the guiding roller 423. When the welding wire is pulled, the welding wire on the surface of the material roller 222 will move from one end to the other end on its surface. During the movement of the welding wire, one end of the welding wire close to the outside of the feed box 2 will shift; When it is necessary to prevent the welding wire from shifting at the gap of the metal conduit pipe during the pulling process of the welding wire, the welding wire gradually rotates at both ends of the material roller 222. When the welding wire is at one end of the material roller 222, the pulled welding wire rotates on the surface of the guiding roller 423. When the welding wire is continuously pulled, the welding wire moves to the surface of another guiding roller 423, thereby avoiding the shift of one end of the welding wire at the gap of the metal conduit pipe due to the continuous rotation of the material roller 222, which may affect the welding quality; Specific Embodiment Four, please refer to Figures 1 to 13 , based on the metal strip arc welding device for metal conduit pipe processing provided in Specific Embodiment Three, this embodiment provides a further technical solution: The cutting component 5 includes a driving gear 51 fixedly connected to the surface of the first driving rod 311 and a driven tooth plate 52 slidably connected inside the operation box 1. The driving gear 51 and the driven tooth plate 52 are in meshing transmission. A moving tooth plate 521 is fixedly connected to one side of the driven tooth plate 52. The cutting component 5 further includes a rotating rod 53 rotatably connected inside the operation box 1 through a support plate. A driven gear 531 and a rotating block 532 are fixedly connected to the surface of the rotating rod 53. The driven gear 531 and the moving tooth plate 521 are in meshing transmission. A fixing plate 533 is fixedly connected to the surface of the rotating block 532. A driving motor 54 is fixedly connected to one end of the fixing plate 533. The output end of the driving motor 54 is fixedly connected to a second driving rod. A cutting disc 541 is fixedly connected to the surface of the second driving rod; It should be noted that a cutting groove for the cutting disc 541 to move is formed inside the operation box 1. A limiting arc plate is fixedly connected to the inside of the end of the leftmost limiting arc strip 611 close to the feeding box 2. The limiting arc plate can prevent the metal conduit pipe from shifting excessively; When it is necessary to cut the adhesion between the metal conduit and the welding wire, the drive motor 54 and the second drive motor 31 are started. The drive motor 54 drives the cutting disc 541 to rotate continuously. The second drive motor 31 drives the driving gear 51 to rotate through the first drive rod 311. The driving gear 51 drives the moving tooth plate 521 to move through the driven tooth plate 52, so that the moving tooth plate 521 drives the rotating rod 53 to rotate through the driven gear 531. Furthermore, the rotating rod 53 drives the cutting disc 541 to move upward through the rotating block 532 and the fixed plate 533, so that the cutting disc 541 cuts the adhesion, thereby preventing the welding wire from adhering to the metal conduit; Specific Embodiment Five, please refer to Figures 1 to 14 , a metal strip arc welding device for processing metal conduits provided according to Specific Embodiment Four. The present embodiment provides a further technical solution: A plurality of rolling columns 12 are rotatably connected inside the operation box 1. A limiting component 6 is arranged inside the operation box 1. The limiting component 6 can limit the metal conduit on the top of the rolling column 12 to prevent it from shifting during the welding process. The limiting component 6 includes a fixed rod 61 rotatably connected inside the operation box 1 and a third drive motor 62 fixedly connected inside the operation box 1. The output end of the third drive motor 62 is fixedly connected with a rotating rod 621. The surface of the rotating rod 621 is fixedly connected with a driving gear 622. The surface of the fixed rod 61 is fixedly connected with a driven gear 612. The driven gear 612 is in meshing transmission with the driving gear 622. A plurality of limiting arc strips 611 are fixedly connected to the surfaces of the fixed rod 61 and the rotating rod 621; It should be noted that the control panel 23 is electrically connected to the first drive motor 112, the second drive motor 31, the drive motor 54 and the third drive motor 62. The start and stop of the first drive motor 112, the second drive motor 31, the drive motor 54 and the third drive motor 62 are controlled through the control program inside the control panel 23, so as to ensure that the arc welding can be carried out fully automatically. A detection component 13 is arranged inside the operation box. The detection component 13 is composed of electrical components such as a camera and an infrared sensor. For example, the detection component 13 can be arranged at the bottom of the welding box 115. The detection component 13 can detect the welding state of the metal conduit (including whether the welding is completed, etc.). By detecting the welding state, the control program inside the control panel 23 is controlled to issue instructions, so as to achieve automatic processing. A rubber layer is arranged on the inner surface of the limiting arc strip 611. The arrangement of the rubber layer can effectively prevent the metal conduit from rotating on the inner surface of the limiting arc strip 611; When it is necessary to fix the metal conduit pipe, start the third driving motor 62. The third driving motor 62 drives the driving gear 622 to rotate through the rotating rod 621, so that the driving gear 622 drives the fixing rod 61 to rotate through the passive gear 612. Further, the fixing rod 61 rotates with the limiting arc strip 611 on the surface of the rotating rod 621, and then the limiting arc strip 611 fixes the metal conduit pipe to prevent it from moving during subsequent arc welding of the metal conduit pipe.

[0025] Working principle: During use, place the metal conduit to be welded inside the operation box 1. Start the third drive motor 62. The third drive motor 62 drives the drive gear 622 to rotate through the rotating rod 621, causing the drive gear 622 to drive the fixed rod 61 to rotate through the passive gear 612. Furthermore, the fixed rod 61 rotates with the limit arc strip 611 on the surface of the rotating rod 621, and then the limit arc strip 611 fixes the metal conduit to prevent it from moving during subsequent arc welding of the metal conduit. When arc welding of the metal conduit is required, fix one end of the welding wire with a mechanical claw and then pull the welding wire to one end of the gap of the metal conduit. Subsequently, start the lifting assembly, and the lifting assembly moves the arc welding gun to the top of the gap of the metal conduit. When the height of one end of the welding wire needs to be adjusted, after the welding wire is pulled to one end of the metal conduit, start the second drive motor 31. The second drive motor 31 drives the rotating bar 32 to rotate through the first drive rod 311, causing the rotating bar 32 to drive the guide roller 321 to rotate. Furthermore, the surface of the guide roller 321 comes into contact with the surface of the welding wire. As the guide roller 321 rotates, one end of the welding wire is aligned with the gap of the metal conduit, thus not affecting the welding quality of the subsequent welding assembly 11 on the metal conduit. When it is necessary to prevent the welding wire from shifting at the gap of the metal conduit, during the pulling process of the welding wire, the welding wire gradually rotates at both ends of the material roller 222. When the welding wire is at one end of the material roller 222, the pulled welding wire rotates on the surface of the guide roller 423. When the welding wire is continuously pulled, the welding wire moves to the surface of the other guide roller 423, thus avoiding the shift of one end of the welding wire at one end of the gap of the metal conduit due to the continuous rotation of the material roller 222, which would affect the welding quality. Then start the first drive motor 112. The first drive motor 112 drives the screw block 114 to move through the first screw 113, causing the screw block 114 to drive the arc welding gun to gradually move through the welding box 115, and then arc weld the metal conduit. When the metal conduit adheres to the welding wire, start the drive motor 54 and the second drive motor 31. The drive motor 54 drives the cutting disc 541 to continuously rotate. The second drive motor 31 drives the driving gear 51 to rotate through the first drive rod 311. The driving gear 51 drives the moving toothed plate 521 to move through the driven toothed plate 52, causing the moving toothed plate 521 to drive the rotating rod 53 to rotate through the driven gear 531. Furthermore, the rotating rod 53 drives the cutting disc 541 to move upward through the rotating block 532 and the fixed plate 533, so that the cutting disc 541 cuts off the adhesion part, thus avoiding the adhesion of the welding wire to the metal conduit; It should be noted that the staff can control the start and stop of the above-mentioned mechanical grippers, driving components (such as the third driving motor 62, the second driving motor 31, the first driving motor 112, the driving motor 54, the driving cylinder, etc.) through the control panel 23. Cameras can be set at different positions in the operation box 1 to collect real-time image information during the processing and display it on the display screen of the control panel 23, so as to facilitate the operation of the staff. Of course, preferably, sensors (such as position sensors, pressure sensors, etc.) are arranged at corresponding positions. For example, a pressure sensor is set on the inner surface of the limit arc bar 611 to control the third driving motor 62 to stop running according to the pressure signal detected by the pressure sensor. Here, no more examples will be given one by one. In short, for whether some moving parts are in place or not, mature detection components in the prior art can be used for detection to obtain corresponding in-place signals and then corresponding control can be carried out. This will not be elaborated in this article.

[0026] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0028] Parallel: The parallel defined in this application is not limited to absolute parallelism. This definition of parallel can be understood as substantially parallel, allowing for situations where it is not absolutely parallel due to factors such as assembly tolerances, design tolerances, and the influence of structural flatness, and allowing for errors within a small angle range. For example, within an assembly error range of within 10 degrees, it can all be understood as a parallel relationship.

[0029] Vertical: The vertical defined in this application is not limited to an absolutely perpendicular intersection (with an included angle of 90 degrees) relationship, allowing for situations where it is not an absolutely perpendicular intersection due to factors such as assembly tolerances, design tolerances, and the influence of structural flatness, and allowing for errors within a small angle range. For example, within an assembly error range of 80 degrees to 100 degrees, it can all be understood as a vertical relationship.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
