Description

Technical Field

[0001] The invention belongs to the technical field of welding, and particularly discloses an online arc welding joint device for a continuous roller pressing production line of color steel plates. Background Art

[0002] Color steel tiles are generally welded by arc welding. When welding color steel tiles, it is necessary to overlap the welding joints of two unconnected sections of color steel tiles. This process is generally done manually. When workers overlap the welded joints of color steel tiles, they need to transport two unconnected sections of color steel tiles to the welding table in advance, then lay one section of color steel tiles on the welding table, and then overlap the welded joints of the other section of color steel tiles on the color steel tiles. During this process, workers need to adjust the welding angle of the color steel tiles. Only when the welding angle of the color steel tiles is determined can workers weld the overlapped joints of the color steel tiles. Although the manual overlapping method can indeed achieve the overlapping of the welding joints of the color steel tiles, the manual overlapping of the welding joints of the color steel tiles is likely to affect the overlapping accuracy of the welding joints of the color steel tiles and the welding accuracy of the color steel tiles. At the same time, when manually overlapping two unconnected sections of color steel tiles, a lot of manpower costs are required, which is not conducive to the rapid welding of color steel tiles produced online by the roller production line.

[0010] In the above technical solution, further, one end of the rotating rod close to the rotating circle is fixedly connected to a power connection end, the power connection end is fixedly connected to the abutment bar, and the part of the abutment bar close to the moving roller is fixedly connected to a storage tube.

[0011] In the above technical solution, further, a sliding bar is inserted into the interior of the support tube, the upper end of the sliding bar abuts against the abutment block, and the lower end of the sliding bar is fixedly connected to an end magnetic block.

[0012] In the above technical solution, further, both ends of the abutment bar are rotatably connected to transmission rollers, one of the transmission rollers is connected to a transmission motor, a pull rope is overlapped on the transmission roller, and the pull rope is wrapped around the rotating tube.

[0013] In the above technical solution, further, a storage cavity is fixedly connected to the abutment bar below the transmission roller, the pull rope is inserted into the interior of the storage cavity, and a reset spring is fixedly connected to one end of the pull rope passing through the storage cavity, and the reset spring is fixedly connected to the storage cavity.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] In actual use, when manually overlapping the welding joints of the color steel tiles, it is easy to affect the overlapping accuracy of the welding joints of the color steel tiles and is not conducive to the rapid welding of the color steel tiles produced online by the roller production line. In order to solve the above problems, the following structure is specially invented.

[0024] Example 1: Please refer to Figure 1-9 As shown, the present invention provides a technical solution: The present invention is an online arc welding joint device for a continuous roll-forming production line of color steel plates, comprising a first frame 4 and a second frame 9, both of which are provided with a supporting groove tube 6, and the inner sides of the first frame 4 and the second frame 9 are fixedly connected to abutment bars 7, and a movable roller 8 is detachably connected to the abutment bar 7, and a driving structure is provided on the movable roller 8; After the color steel tile body 3 is rolled and produced, the support groove tube 6 and the abutment bar 7 on the first frame 4 and the second frame 9 can stably support the color steel tile body 3 after rolling, which can be beneficial to the online welding of the color steel tile body 3 after rolling. When the color steel tile body 3 abuts on the support groove tube 6 and the abutment bar 7, the color steel tile body 3 can move on the support groove tube 6 and the abutment bar 7 through the moving roller 8, which can facilitate the staff to adjust the welding joint of the color steel tile body 3.

[0025] Example 2: Based on Example 1, the present invention provides a technical solution. Different from Example 1, this embodiment can achieve rapid heat dissipation at the welding joints of the color steel tiles when the color steel tiles are welded.

[0026] The movable roller 8 includes a rotating tube 87 rotatably connected to the abutment bar 7, a connecting cavity 810 fixedly connected to the rotating tube 87, a second receiving ring 86 fixedly connected to the connecting cavity 810, a first receiving ring 84 distributed on the side of the second receiving ring 86 facing away from the abutment bar 7, a paddle 85 fixedly connected between the second receiving ring 86 and the first receiving ring 84, and an abutment block 81 inserted into both the first receiving ring 84 and the second receiving ring 86; The second storage ring 86 and the first storage ring 84 are annular structures. When the second storage ring 86 and the first storage ring 84 drive the paddle 85 to rotate, the paddle 85 can drive the color steel tile body 3 on the supporting groove tube 6 and the abutment strip 7 to quickly dissipate heat, which can improve the welding quality of the color steel tile body 3.

[0027] The first frame 4 and the second frame 9 are distributed on one side of the rolling device 1. A welding robot 2 is provided near the first frame 4 and the second frame 9. An angle adjustment structure 5 is connected between the support groove tube 6 and the first frame 4 and the second frame 9. In actual use, the support groove tube 6 and the abutment bar 7 are used to support the color steel tile body 3 pressed by the roller pressing device 1. When the color steel tile body 3 is placed on the support groove tube 6 and the abutment bar 7, the movable roller 8 can support the color steel tile body 3, and the color steel tile body 3 can be moved on the support groove tube 6 and the abutment bar 7 by the movable roller 8, which facilitates the welding robot 2 to weld the color steel tile body 3 on the support groove tube 6 and the abutment bar 7; When the color steel tile body 3 moves on the support groove tube 6 and the abutment bar 7 through the moving roller 8, the abutment block 81 can abut on the color steel tile body 3, and the paddle 85 fixedly connected between the second storage ring 86 and the first storage ring 84 can disturb the smoke generated during the welding of the color steel tile body 3, thereby avoiding the smoke generated during the welding of the color steel tile body 3 from concentrating on the welding port of the color steel tile body 3, and can also achieve rapid heat dissipation at the welding port of the color steel tile body 3, thereby improving the welding quality of the color steel tile body 3.

[0028] Example 3: Based on Example 2, the present invention provides a technical solution. The difference from Example 2 is that this embodiment can adjust whether the abutment block 81 abuts against the color steel tile body 3, which is beneficial to the rapid heat dissipation of the welding port of the color steel tile body 3 and improves the welding quality of the color steel tile body 3.

[0029] The first storage ring 84 and the second storage ring 86 are both provided with an air inlet hole 83. The first storage ring 84 and the second storage ring 86 are both fixedly connected to a support tube 82. The support tube 82 on the second storage ring 86 is fixedly connected to the interior of the connecting cavity 810. The support tube 82 can stably support the first storage ring 84 and the second storage ring 86, and can avoid the first storage ring 84 and the second storage ring 86 from being deformed during use. When the color steel tile body 3 is welded, the heat generated during the welding of the color steel tile body 3 will be concentrated around the paddle 85 through the air inlet hole 83, which can help the paddle 85 to drive the heat and smoke generated during the welding of the color steel tile body 3 to move.

[0030] The interior of the rotating tube 87 is penetrated by a plug-in component 88, which includes a rotating rod 883 that penetrates the interior of the rotating tube 87. The end of the rotating rod 883 is fixedly connected to a first electromagnet 881. The first electromagnet 881 is rotatably connected to the support tube 82 on the first receiving ring 84. During actual use, the rotating tube 87 and the abutment bar 7 are rotatably connected, which enables the color steel tile body 3 to be overlapped on the support groove tube 6 and the abutment bar 7. The color steel tile body 3 can be moved on the support groove tube 6 and the abutment bar 7 through the first storage ring 84 and the second storage ring 86, so that the welding overlap position of the color steel tile body 3 can be adjusted.

[0031] The rotating rod 883 is fixedly connected to a second electromagnet 882 and a rotating ring 884. The second electromagnet 882 is rotatably connected to the connecting cavity 810, and the rotating ring 884 is rotatably connected to the rotating tube 87. When the rotating ring 884 is embedded in the rotating tube 87, the rotating ring 884 can drive the rotating rod 883 to rotate stably inside the rotating tube 87. At the same time, the rotating ring 884 can seal the inner cavity of the rotating tube 87 to prevent external humid gas from entering the interior of the rotating tube 87.

[0032] One end of the rotating rod 883 close to the rotating circle 884 is fixedly connected to the power connection end 89, which is fixedly connected to the abutment bar 7. The portion of the abutment bar 7 close to the moving roller 8 is fixedly connected to the receiving tube 10. When the first storage ring 84 and the second storage ring 86 drive the paddle 85 to rotate, the paddle 85 can drive the smoke generated during welding of the color steel tile body 3 to be transported to the inside of the storage tube 10. The discharge end of the storage tube 10 can be connected to an external device, so that the smoke generated during welding of the color steel tile body 3 can be concentratedly stored inside the external device.

[0033] A sliding bar 811 is inserted into the interior of the support tube 82. The upper end of the sliding bar 811 abuts against the abutment block 81, and the lower end of the sliding bar 811 is fixedly connected to an end magnetic block 812. The magnetic poles of the end magnetic block 812 and the magnetic poles of the first electromagnet 881 and the second electromagnet 882 repel each other, and the power terminal 89 is connected to an external power source. When the external power source provides power to the power terminal 89, the first electromagnet 881 and the second electromagnet 882 can work. At this time, the end magnetic block 812 can move away from the first electromagnet 881 and the second electromagnet 882. Since the upper end of the sliding bar 811 abuts against the abutting block 81, when the end magnetic block 812 and the first electromagnet 881 and the second electromagnet 882 move away from each other, the end magnetic block 812 can push the abutting block 81 through the sliding bar 811, so that the abutting block 81 and the color steel tile body 3 can be abutted. It should be noted that there are multiple movable rollers 8 on the abutment bar 7, and the multiple movable rollers 8 can be divided into two groups A and B. During actual use, the two groups A and B movable rollers 8 can work alternately. When the external power supply supplies power to the power terminal 89 in the movable roller 8 of group A, the power terminal 89 in the movable roller 8 of group B is not supplied with power. This can reduce the number of contacts between the color steel tile body 3 and the movable roller 8, and can avoid the abutment of more abutment blocks 81 and the color steel tile body 3, which affects the heat and smoke generated when the blades 85 drive the color steel tile body 3 to dissipate during welding.

[0034] Example 4: Based on Example 3, the present invention provides a technical solution. Different from Example 3, this embodiment can quickly drive the moving roller 8 to rotate, so that the moving roller 8 drives the color steel tile body 3 to move on the supporting groove tube 6 and the abutment bar 7.

[0035] Both ends of the abutment bar 7 are rotatably connected to transmission rollers 13, one of which is connected to a transmission motor 11, and a pull rope 12 is connected to the transmission roller 13, and the pull rope 12 is wound around the rotating tube 87; When the output shaft of the transmission motor 11 drives the transmission roller 13 to rotate, the transmission roller 13 can reel in the pull rope 12 , so that the pull rope 12 drives the first receiving ring 84 and the second receiving ring 86 to rotate through the rotating tube 87 .

[0036] A receiving chamber 14 is fixedly connected to the contact bar 7 below the transmission roller 13. The pull rope 12 is inserted into the receiving chamber 14. A return spring 15 is fixedly connected to one end of the pull rope 12 that passes through the receiving chamber 14. The return spring 15 is fixedly connected to the receiving chamber 14. When the transmission roller 13 reels the pull rope 12, the pull rope 12 can stretch the reset spring 15 inside the storage chamber 14. At this time, the reset spring 15 can store energy to work. When the transmission motor 11 is not working, the repulsive force generated by the reset spring 15 will drive the pull rope 12 to reset, which can facilitate the subsequent pull rope 12 to drive the first storage ring 84 and the second storage ring 86 to rotate through the rotating tube 87.

[0037] The supporting groove tube 6 and the abutting bar 7 are in contact with the color steel tile body 3, the upper end of the abutting block 81 is in contact with the color steel tile body 3, and there are multiple movable rollers 8 distributed on the abutting bar 7; During actual use, when the output shaft of the transmission motor 11 drives the transmission roller 13 to rotate, the transmission roller 13 can reel in the pull rope 12, so that the pull rope 12 drives the first storage ring 84 and the second storage ring 86 to rotate through the rotating tube 87. Since the first storage ring 84 and the second storage ring 86 are both provided with abutment blocks 81, when the first storage ring 84 and the second storage ring 86 drive the abutment blocks 81 to rotate, the abutment blocks 81 can drive the color steel tile body 3 to move on the supporting groove tube 6 and the abutment bar 7; At the same time, there are multiple moving rollers 8 on the contact strip 7, and the multiple moving rollers 8 can be divided into two groups A and B. Please refer to the attached instructions. Figure 8 In actual use, the two groups of moving rollers 8, A and B, can work alternately. This can be understood that separate pull ropes 12 are provided on the moving rollers 8 of group A and the moving rollers 8 of group B. The pull ropes 12 on the two groups A and B are also provided with separate transmission motors 11. When the moving rollers 8 of group A drive the color steel tile body 3 to move, the abutment blocks 81 on the moving rollers 8 of group B do not abut against the color steel tile body 3, which can realize the quick reset of the pull ropes 12 on the moving rollers 8 of group B. When the moving rollers 8 of group A drive the color steel tile body 3 to move, the abutment blocks 81 on the moving rollers 8 of group B do not abut against the color steel tile body 3. When the roller 8 drives the color steel tile body 3 to move, the abutment block 81 on the moving roller 8 of group A does not abut the color steel tile body 3, which can realize the rapid reset of the pull rope 12 on the moving roller 8 of group A, and thus realize the alternating operation of the two groups of moving rollers 8 of A and B. When the two groups of moving rollers 8 of A and B can work alternately, the color steel tile body 3 can be realized to move non-stop on the support groove tube 6 and the abutment bar 7, which can improve the efficiency of the color steel tile body 3 moving on the support groove tube 6 and the abutment bar 7.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
