Description

Technical Field

[0001] This invention belongs to the field of welding technology, and specifically discloses an online arc welding joint device for a continuous roll forming production line of color steel plates. Background Technology

[0002] Color steel tiles are generally welded using electric arc welding. When welding color steel tiles, the weld joints of two unconnected color steel tiles need to be overlapped. This process is usually done manually.

[0003] When workers overlap the weld joints of color steel tiles, they need to transport two unconnected sections of color steel tiles to the welding table in advance. Then, one section of color steel tile is laid on the welding table, and the weld joint of the other section of color steel tile is overlapped on the color steel tile. During this process, workers need to adjust the welding angle of the color steel tile. Only after the welding angle of the color steel tile is determined can workers weld the overlap joint of the color steel tile.

[0004] Although manual overlapping can indeed achieve the overlapping of the weld joints of color steel tiles, it can easily affect the overlapping accuracy of the weld joints and the welding accuracy of the color steel tiles. At the same time, manually overlapping two unconnected color steel tiles requires a lot of labor costs, which is not conducive to the rapid welding of color steel tiles produced online on the roll forming production line.

[0005] To address this issue, we propose a welding joint device for color steel tiles. Summary of the Invention

[0006] In view of this, the purpose of this invention is to propose an online arc welding overlap device for a continuous roll forming production line of color steel sheets, so as to solve the problem that when manually overlapping the weld joints of color steel sheets, it is easy to affect the overlap accuracy of the weld joints and hinder the rapid welding of color steel sheets produced online on the roll forming production line.

[0007] To achieve the above objectives, the present invention provides an online arc welding joint device for a continuous roll forming production line of color steel plates, comprising a first frame and a second frame, both the first frame and the second frame being provided with support grooves, both the inner sides of the first frame and the second frame being fixedly connected with abutment strips, the abutment strips being detachably connected with movable rollers, and the movable rollers being provided with a drive structure.

[0008] The movable roller includes a rotating tube rotatably connected to the abutment bar, a connecting cavity fixedly connected to the rotating tube, a second storage ring fixedly connected to the connecting cavity, a first storage ring distributed on the side of the second storage ring away from the abutment bar, a paddle fixedly connected between the second storage ring and the first storage ring, and an abutment block inserted into both the first storage ring and the second storage ring.

[0009] In the above technical solution, the first frame and the second frame are distributed on one side of the roller pressing device, and a welding robot is provided near the first frame and the second frame. An angle adjustment structure is connected between the support groove tube and the first frame and the second frame.

[0010] In the above technical solution, both the first and second storage rings are provided with air inlets, and both the first and second storage rings are fixedly connected with support tubes, with the support tube on the second storage ring being fixedly connected inside the connecting cavity.

[0011] In the above technical solution, further, a connector is inserted through the interior of the rotating tube, the connector including a rotating rod that passes through the interior of the rotating tube, and a first electromagnet is fixedly connected to the end of the rotating rod. The first electromagnet is rotatably connected to the support tube on the first storage ring.

[0012] In the above technical solution, a second electromagnet and a rotating ring are fixedly connected to the rotating rod. The second electromagnet is rotatably connected to the connecting cavity, and the rotating ring is rotatably connected to the rotating tube.

[0013] In the above technical solution, further, an electrical terminal is fixedly connected to one end of the rotating rod near the rotating ring, the electrical terminal is fixedly connected to the abutment strip, and a storage tube is fixedly connected to the part of the abutment strip near the moving roller.

[0014] In the above technical solution, a sliding strip is further inserted inside the support tube, the upper end of the sliding strip abuts against the abutting block, and an end magnet is fixedly connected to the lower end of the sliding strip.

[0015] In the above technical solution, both ends of the abutment strip are rotatably connected to transmission rollers, one of the transmission rollers is connected to a transmission motor, a pull rope is attached to the transmission roller, and the pull rope is wound around the rotating tube.

[0016] In the above technical solution, a storage cavity is further fixedly connected to the abutment bar below the transmission roller, the pull rope is inserted into the inside of the storage cavity, and a return spring is fixedly connected to one end of the pull rope and the storage cavity, and the return spring is fixedly connected to the storage cavity.

[0017] In the above technical solution, further, the supporting groove tube and the abutting strip abut against the color steel tile body, the upper end of the abutting block abuts against the color steel tile body, and multiple movable rollers are distributed on the abutting strip.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The support groove tube in the welding joint device can be used with the abutment strip to support the color steel tile body, which can facilitate the welding joint of two unconnected color steel tile bodies and facilitate the online arc welding of the welding joint of the color steel tile body by the welding robot.

[0020] 2. When the support groove tube in the welding joint device is used in conjunction with the abutment strip to weld two unconnected sections of the color steel tile body, the output shaft of the drive motor can pull the pull rope through the drive roller. At this time, the pull rope can drive the moving roller on the abutment strip to rotate, which can realize that the moving roller drives the color steel tile body on the abutment strip to move, so as to realize the welding robot to quickly weld the weld joint of the color steel tile body.

[0021] 3. When the moving roller in the welding joint device moves the color steel tile body on the abutment strip, the blade in the moving roller can drive the welding fumes generated during the welding of the color steel tile body to be transported into the inside of the collection pipe, which can prevent the welding fumes from concentrating at the welding joint of the color steel tile body and improve the welding quality of the color steel tile body.

[0022] 4. When the moving rollers in the welding joint device drive the color steel tile body on the abutment strip to move, the external controller can intermittently control the first electromagnet and the second electromagnet in the moving rollers to work, thereby enabling the abutment blocks in multiple moving rollers to work intermittently, which can facilitate the rapid disturbance of welding fumes during the welding of the color steel tile body by the paddle blades.

[0033] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0035] In practical use, when manually overlapping the weld joints of color steel tiles, it is easy to affect the overlap accuracy of the weld joints and hinder the rapid welding of color steel tiles produced online on the roll forming production line. To solve the above problems, the following structure has been invented.

[0036] Example 1: Please refer to Figure 1-9 As shown, the present invention provides a technical solution:

[0037] The present invention is an online arc welding joint device for a continuous roll forming production line of color steel plate, including a first frame 4 and a second frame 9. Both the first frame 4 and the second frame 9 are provided with support groove tubes 6. Both the first frame 4 and the second frame 9 are fixedly connected to the inner side of the first frame 4 and the second frame 9. A movable roller 8 is detachably connected to the abutment strip 7, and a driving structure is provided on the movable roller 8.

[0038] After the color steel tile body 3 is produced by roll forming, the support groove tube 6 and the abutment strip 7 on the first frame 4 and the second frame 9 can stably support the color steel tile body 3 after roll forming, which is conducive to the online welding of the color steel tile body 3 after roll forming. When the color steel tile body 3 abuts on the support groove tube 6 and the abutment strip 7, the color steel tile body 3 can move on the support groove tube 6 and the abutment strip 7 through the moving roller 8, which makes it convenient for the staff to adjust the welding joint of the color steel tile body 3.

[0039] Example 2: Based on Example 1, the present invention provides a technical solution that differs from Example 1 in that it enables rapid heat dissipation at the weld joint of the color steel tile during welding.

[0040] The movable roller 8 includes a rotating tube 87 rotatably connected to the abutment bar 7. A connecting cavity 810 is fixedly connected to the rotating tube 87. A second storage ring 86 is fixedly connected to the connecting cavity 810. A first storage ring 84 is distributed on the side of the second storage ring 86 away from the abutment bar 7. A paddle 85 is fixedly connected between the second storage ring 86 and the first storage ring 84. An abutment block 81 is inserted into both the first storage ring 84 and the second storage ring 86.

[0041] The second storage ring 86 and the first storage ring 84 are ring structures. When the second storage ring 86 and the first storage ring 84 drive the blade 85 to rotate, the blade 85 can drive the color steel tile body 3 on the support groove tube 6 and the abutment strip 7 to dissipate heat quickly, which can improve the welding quality of the color steel tile body 3.

[0042] The first frame 4 and the second frame 9 are distributed on one side of the roller pressing device 1. At the same time, a welding robot 2 is set 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.

[0043] In actual use, the support groove tube 6 and the abutment strip 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 strip 7, the moving roller 8 can support the color steel tile body 3, and the color steel tile body 3 can move on the support groove tube 6 and the abutment strip 7 through the moving 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 strip 7.

[0044] When the corrugated steel tile body 3 moves on the support groove tube 6 and the abutment strip 7 via the moving roller 8, the abutment block 81 can abut against the corrugated steel tile body 3. The blade 85 fixedly connected between the second storage ring 86 and the first storage ring 84 can turbulentize the smoke and dust generated during the welding of the corrugated steel tile body 3, which can prevent the smoke and dust generated during the welding of the corrugated steel tile body 3 from concentrating at the welding joint of the corrugated steel tile body 3, and can also achieve rapid heat dissipation at the welding joint of the corrugated steel tile body 3, thereby improving the welding quality of the corrugated steel tile body 3.

[0045] Example 3: Based on Example 2, the present invention provides a technical solution. Unlike Example 2, this example allows for adjustment of whether the abutting block 81 abuts against the color steel tile body 3, which is beneficial for the rapid heat dissipation of the weld joint of the color steel tile body 3 and improves the welding quality of the color steel tile body 3.

[0046] The first storage ring 84 and the second storage ring 86 are both provided with air inlets 83, and the first storage ring 84 and the second storage ring 86 are both fixedly connected with support tubes 82. The support tube 82 on the second storage ring 86 is fixedly connected to the inside of the connecting cavity 810.

[0047] The support tube 82 can stably support the first storage ring 84 and the second storage ring 86, which can prevent the first storage ring 84 and the second storage ring 86 from deforming during use. When the color steel tile body 3 is being welded, the heat generated during the welding of the color steel tile body 3 will be concentrated around the blade 85 through the air inlet 83, which can help the blade 85 to move the heat and smoke generated during the welding of the color steel tile body 3.

[0048] A connector 88 passes through the interior of the rotating tube 87. The connector 88 includes a rotating rod 883 that passes through the interior of the rotating tube 87. A first electromagnet 881 is fixedly connected to the end of the rotating rod 883. The first electromagnet 881 is rotatably connected to the support tube 82 on the first storage ring 84.

[0049] In actual use, the rotating tube 87 and the abutment strip 7 are rotatably connected. This allows the color steel tile body 3 to move on the support groove tube 6 and the abutment strip 7 when it overlaps with the support groove tube 6 and the abutment strip 7. This allows the welding overlap position of the color steel tile body 3 to be adjusted.

[0050] A second electromagnet 882 and a rotating ring 884 are fixedly connected to the rotating rod 883. 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.

[0051] When the rotating ring 884 is embedded inside 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.

[0052] A power terminal 89 is fixedly connected to one end of the rotating rod 883 near the rotating ring 884. The power terminal 89 is fixedly connected to the abutment strip 7. A storage tube 10 is fixedly connected to the part of the abutment strip 7 near the moving roller 8.

[0053] When the first collection ring 84 and the second collection ring 86 drive the blade 85 to rotate, the blade 85 can transport the fumes from the welding of the color steel tile body 3 to the inside of the collection pipe 10. The discharge end of the collection pipe 10 can be connected to external equipment, which can realize the centralized collection of the fumes from the welding of the color steel tile body 3 inside the external equipment.

[0054] A sliding bar 811 is inserted inside the support tube 82. The upper end of the sliding bar 811 abuts against the abutting block 81, and the lower end of the sliding bar 811 is fixedly connected to an end magnet 812.

[0055] The magnetic poles of the end magnetic block 812 repel the magnetic poles of the first electromagnet 881 and the second electromagnet 882. 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 moves away from the first electromagnet 881 and the second electromagnet 882, 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 abut against each other.

[0056] It should be noted that there are multiple movable rollers 8 on the abutment strip 7. These multiple movable rollers 8 can be divided into two groups, A and B. In actual use, the movable rollers 8 in groups A and B can work alternately. When the external power supply supplies power to the electrical terminal 89 in group A of movable rollers 8, the electrical terminal 89 in group B of movable rollers 8 is not supplied with power. This can reduce the number of contacts between the color steel tile body 3 and the movable rollers 8, and can avoid the impact on the dissipation of heat and fumes generated when the abutment block 81 abuts against the color steel tile body 3 during the welding of the color steel tile body 3 by the blade 85 when a large number of abutment blocks 81 abut against the color steel tile body 3.

[0057] Example 4: Based on Example 3, the present invention provides a technical solution. Unlike Example 3, this example can quickly drive the movable roller 8 to rotate, so that the movable roller 8 can drive the color steel tile body 3 to move on the support groove tube 6 and the abutment strip 7.

[0058] Both ends of the abutment bar 7 are rotatably connected to transmission rollers 13. One of the transmission rollers 13 is connected to a transmission motor 11. A pull rope 12 is attached to the transmission roller 13. The pull rope 12 and the rotating tube 87 are wrapped around each other.

[0059] When the output shaft of the drive motor 11 drives the drive roller 13 to rotate, the drive roller 13 can wind up 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.

[0060] A storage cavity 14 is fixedly connected to the abutment bar 7 below the transmission roller 13. The pull rope 12 is inserted into the storage cavity 14. A return spring 15 is fixedly connected to one end of the pull rope 12 and the storage cavity 14. The return spring 15 is fixedly connected to the storage cavity 14.

[0061] When the drive roller 13 winds up the pull rope 12, the pull rope 12 can be stretched by the return spring 15 inside the storage cavity 14. At this time, the return spring 15 can store force. When the drive motor 11 is not working, the repulsive force generated by the return spring 15 will drive the pull rope 12 to reset, which makes it easier for the pull rope 12 to drive the first storage ring 84 and the second storage ring 86 to rotate through the rotating tube 87.

[0062] The support groove tube 6 and the abutment strip 7 abut against the color steel tile body 3, the upper end of the abutment block 81 abuts against the color steel tile body 3, and multiple movable rollers 8 are distributed on the abutment strip 7.

[0063] In actual use, when the output shaft of the transmission motor 11 drives the transmission roller 13 to rotate, the transmission roller 13 can wind up 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 abutting blocks 81, when the first storage ring 84 and the second storage ring 86 drive the abutting blocks 81 to rotate, the abutting blocks 81 can drive the color steel tile body 3 to move on the support groove tube 6 and the abutting strip 7.

[0064] Meanwhile, there are multiple movable rollers 8 on the abutment bar 7. These multiple movable rollers 8 can be divided into two groups, A and B. Please refer to the attached instructions. Figure 8 In actual use, the two sets of moving rollers 8, A and B, can work alternately. This means that each set of moving rollers 8, A and B, is equipped with a separate pull rope 12, and each pull rope 12 is also equipped with a separate drive motor 11. When the moving roller 8 of set A moves the corrugated steel sheet body 3, the abutment block 81 on the moving roller 8 of set B does not abut against the corrugated steel sheet body 3. This allows the pull rope 12 on the moving roller 8 of set B to quickly reset. When the roller 8 drives the color steel tile body 3 to move, the abutment block 81 on the A group of moving rollers 8 does not abut against the color steel tile body 3. This allows the pull rope 12 on the A group of moving rollers 8 to quickly reset. This allows the A and B groups of moving rollers 8 to work alternately. When the A and B groups of moving rollers 8 work alternately, the color steel tile body 3 can move continuously on the support groove tube 6 and the abutment strip 7, which can improve the efficiency of the color steel tile body 3 moving on the support groove tube 6 and the abutment strip 7.

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