Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of steel bar welding, and more specifically, to a butt welding device for steel bars with uniform welding. Background Art

[0002] In many engineering fields such as building construction and bridge construction, the operation of steel bar connection is crucial, and the butt welding device for steel bars, as a key tool to achieve efficient and reliable connection, is widely used.

[0003] The existing butt welding device for steel bars mainly consists of a welding transformer, electrodes, a feeding mechanism, and control components. Among them, the welding transformer is responsible for providing the current required for welding. The electrodes are divided into a left electrode and a right electrode, which are used to conduct the current and press the ends of the steel bars tightly. The feeding mechanism is used to push the steel bars during the welding of the steel bars to achieve the melting and extrusion processes. The control components control the welding process according to a specific program.

[0004] However, in the actual welding process of the existing butt welding device for steel bars, since most of the feeding mechanisms are driven by cylinders or hydraulic cylinders, there are problems of insufficient accuracy and stability during the welding process. Especially during the conveying process, it is difficult to accurately control the feeding speed and position of the steel bars, which is likely to cause uneven heating of the welded parts of the steel bars during welding. For example, in some large building projects, due to the large number of steel bar sizes and quantities, the instability of the feeding mechanism is likely to cause over-welding at the welded joints, resulting in embrittlement of the steel bar material and affecting the overall strength. Or, there may be cases of incomplete penetration, greatly reducing the connection strength of the steel bars. And during welding, due to the long-term placement of the steel bars to be welded or at the time of factory production, there is a large amount of rust or poor flatness at the welding ends of the steel bars. After docking, it is likely to affect the current conduction efficiency between the two steel bars to be welded, thereby further affecting the welding strength and welding uniformity of the steel bars. Summary of the Invention

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0025] As Figures 1 to 9 shown, it shows a butt welding device for steel bars with uniform welding in an embodiment of this disclosure, including two left electrodes 1 and two right electrodes 2, and also including a butt welding frame 3, an electrode bearing part 001, and a steel bar conveying assembly.

[0026] Among them, both the left electrode 1 and the right electrode 2 are common mechanisms of steel bar butt welding equipment in the prior art. Their main function is to conduct current for butt welding of steel bars. During actual welding, a corresponding welding transformer needs to be equipped to provide a stable current to meet the welding requirements of the steel bars.

[0027] As Figure 5 shown, there are two electrode bearing parts 001, which are symmetrically arranged. The left electrode 1 and the right electrode 2 are provided on each electrode bearing part 001. The right electrode 2 can slide towards the left electrode 1. One electrode bearing part 001 is arranged on the butt welding frame 3, and the other electrode bearing part 001 is arranged on the butt welding frame 3 through the electrode position adjusting part 002.

[0028] Among them, the electrode bearing part 001 includes a U-shaped bearing plate 6, a U-shaped position adjusting plate 7, a limiting rod 8 and a position adjusting spring 9. The U-shaped bearing plate 6 is arranged on the butt welding frame 3 or the electrode position adjusting part 002. The left electrode 1 is installed on the U-shaped bearing plate 6. The U-shaped position adjusting plate 7 penetrates and is slidably arranged on one side of the U-shaped bearing plate 6. The limiting rod 8 penetrates and is slidably arranged on the U-shaped bearing plate 6. One end of the limiting rod 8 is connected to one end of the U-shaped position adjusting plate 7. The position adjusting spring 9 is arranged between the U-shaped bearing plate 6 and the U-shaped position adjusting plate 7, and the limiting rod 8 is located inside the position adjusting spring 9.

[0029] Among them, the electrode position adjusting part 002 includes an electrode position adjusting cylinder 10 and an electrode pressure sensor 11. The electrode position adjusting cylinder 10 is installed on the butt welding frame 3, and the electrode pressure sensor 11 is installed on the output end of the electrode position adjusting cylinder 10. The detection end of the electrode pressure sensor 11 is connected to the U-shaped bearing plate 6.

[0030] Specifically, when the electrode position adjusting cylinder 10 is started, the output end of the electrode position adjusting cylinder 10 will drive the motor pressure sensor to move. Through the movement of the motor pressure sensor, the U-shaped bearing plate 6 can be driven to move, so as to adjust the positions of the left electrode 1 and the right electrode 2, and clamp the steel bar with the two corresponding right electrode 2 and left electrode 1. After the two right electrodes 2 clamp the steel bar, with the movement of the steel bar, the right electrode 2 will be driven to move towards the left electrode 1. When the right electrode 2 moves towards the left electrode 1, it will drive the U-shaped position adjusting plate 7 to move inside the U-shaped bearing plate 6. By the movement of the U-shaped position adjusting plate 7, the position adjusting spring 9 is compressed. Under the sliding of the limiting rod 8, the stability of the sliding of the U-shaped position adjusting plate 7 is increased to ensure the stability of the movement of the right electrode 2.

[0031] As Figure 6As shown in the figure, there are two groups of the above-mentioned steel bar conveying components, which are symmetrically arranged on the butt welding frame 3. The electrode bearing part 001 is located between the two steel bar conveying components. The steel bar conveying component includes a clamping and conveying part 003. There are two clamping and conveying parts 003, and they are symmetrically arranged. One clamping and conveying part 003 is arranged on the butt welding frame 3, and the other clamping and conveying part 003 is arranged on the butt welding frame 3 through a clamping position adjusting part 004. A number of conveying rollers 4 capable of conveying steel bars and a number of clamping blocks 5 capable of fixing steel bars are arranged on the clamping and conveying part 003.

[0032] Among them, the clamping and conveying part 003 includes a conveying frame 12, a feeding frame 13, a universal coupling 14, a synchronous conveying motor 15, a conveying shaft 16 and a conveying worm gear 17. The conveying frame 12 is arranged on the butt welding frame 3 or the clamping position adjusting part 004. There are a number of feeding frames 13, and a number of feeding frames 13 are arranged in a row in pairs on the conveying frame 12. The feeding frames 13 correspond to the conveying rollers 4 one by one. The conveying rollers 4 are rotatably arranged on the feeding frames 13. There are a number of universal couplings 14, and the universal couplings 14 correspond to the feeding frames 13 in pairs one by one. The universal couplings 14 are rotatably arranged on the conveying frame 12. The two ends of the universal coupling 14 are respectively connected to one end of the corresponding conveying roller 4. The synchronous conveying motor 15 is installed at one end of the conveying frame 12. The conveying shaft 16 is rotatably arranged on the conveying frame 12. One end of the conveying shaft 16 is connected to the output end of the synchronous conveying motor 15. There are a number of conveying worm gears 17, and the conveying worm gears 17 correspond to the universal couplings 14 one by one. The conveying worm gears 17 are arranged on the universal couplings 14. There are a number of conveying worm shafts 18, and the conveying worm shafts 18 are arranged on the conveying shaft 16. The conveying worm shafts 18 correspond to the conveying worm gears 17 one by one. The conveying worm shafts 18 are meshed with the conveying worm gears 17. There are a number of clamping cylinders 19, and a number of clamping cylinders 19 are arranged in a row in pairs on the conveying frame 12. The clamping cylinders 19 correspond to the clamping blocks 5 one by one. The clamping blocks 5 are arranged at the output end of the clamping cylinders 19.

[0033] Specifically, when the synchronous conveying motor 15 is started, the output end of the synchronous conveying motor 15 drives the conveying shaft 16 to rotate. The rotation of the conveying shaft 16 drives the conveying worm shaft 18 to rotate. The rotation of the conveying worm shaft 18 drives the conveying worm gear 17 to rotate. The rotation of the conveying worm gear 17 can drive the universal coupling 14 connected thereto to rotate. Through the rotation of the universal coupling 14, the conveying roller 4 can be driven to rotate. When conveying the steel bar, the steel bar is brought into contact with the conveying roller 4, and the rotation of the conveying roller 4 drives the steel bar to move. In order to increase the contact friction force with the steel bar, a rubber pad can be covered on the surface of the conveying roller 4 to improve the stability of steel bar conveying. Moreover, when the conveying worm shaft 18 drives the conveying worm gear 17 to rotate, through the meshing of the conveying worm shaft 18 and the conveying worm gear 17, a good self-locking effect can be achieved, and the stability of steel bar conveying can be improved.

[0034] After the steel bar is conveyed to a specific position, in order to further increase the stability of the steel bar, the clamping cylinder 19 can be activated to drive the clamping block 5 to move. By contacting the clamping block 5 with the steel bar, while increasing the stability of the steel bar, the clamping blocks 5 arranged in a straight line can also correct the steel bar to improve the uniformity of the butt joint of the steel bar.

[0035] It should be added that the two feeding frames 13 arranged in pairs are symmetrically arranged in an inclined manner, and a conveying cavity is formed between the corresponding two conveying rollers 4. When conveying the steel bar, after placing the steel bar in the conveying cavity, the stability of the steel bar can be further increased.

[0036] The two clamping cylinders 19 arranged in pairs are symmetrically arranged in an inclined manner, and a clamping cavity is formed between the corresponding two clamping blocks 5. Specifically, after the conveying roller 4 contacts and squeezes the steel bar, through the extrusion of the clamping block 5, the steel bar can be corrected from multiple angles to further improve the neatness during the butt joint of the steel bar.

[0037] The above-mentioned clamping position adjusting part 004 includes a feeding position adjusting cylinder 20 and a feeding pressure sensor 21. The feeding position adjusting cylinder 20 is installed on the butt welding frame 3, and the feeding pressure sensor 21 is installed on the output end of the feeding position adjusting cylinder 20. The detection end of the feeding pressure sensor 21 is connected to one end of the conveying frame 12.

[0038] Specifically, when the feeding position adjusting cylinder 20 is started, the output end of the feeding position adjusting cylinder 20 drives the feeding pressure sensor 21 to move. Through the movement of the feeding and pressing sensor, the conveying frame 12 is driven to move, so that the conveying roller 4 can clamp the steel bar, and through the detection of the feeding pressure sensor 21, the pressure of the conveying roller 4 squeezing the steel bar can be adjusted to prevent slippage between the steel bar and the conveying roller 4.

[0039] As Figure 8 shown, it should be added that a detection cylinder 22 is installed on one side of the butt welding frame 3, and a position detection sensor 23 capable of detecting the end of the steel bar is installed at the output end of the detection cylinder 22. Specifically, when the detection cylinder 22 is started, the output end of the detection cylinder 22 will drive the position detection sensor 23 to move. By adjusting the position of the position detection sensor 23, the position of the welding end of the steel bar can be detected by the position detection sensor 23, so that the left electrode 1 and the right electrode 2 can accurately clamp the steel bar for butt welding operation of the steel bar.

[0040] As Figure 9As shown in the figure, it is further supplemented and explained that a deburring part 005 capable of grinding the welded ends of steel bars is also installed at one end of the butt welding frame 3 away from the detection cylinder 22. The deburring part 005 includes a deburring cylinder 24, a deburring frame 25, a deburring motor 26 and a deburring grinding wheel 27. The deburring cylinder 24 is installed on one side of the butt welding frame 3, the deburring frame 25 is arranged at the output end of the deburring cylinder 24, the deburring motor 26 is installed on the deburring frame 25, and the deburring grinding wheel 27 is arranged at the output end of the deburring motor 26.

[0041] Specifically, by arranging the deburring part 005 on one side of the butt welding frame 3, when butt welding steel bars, first start the deburring cylinder 24 to drive the deburring grinding wheel 27 to move between the left electrode 1 and the right electrode 2. Then, place the steel bars to be welded on the two steel bar conveying components respectively, and drive the steel bars to move through the steel bar conveying components, so that the welded ends of the two steel bars are respectively in contact with both ends of the deburring grinding wheel 27. This can not only accurately position the welded ends of the steel bars, but also drive the deburring grinding wheel 27 to rotate by starting the deburring motor 26, so as to grind the welded edges of the steel bars to remove impurities on the welding surface or level the welding surface. Secondly, after grinding the welding surface of the steel bars, adjust the positions of the left electrode 1 and the right electrode 2, clamp the steel bars, and then drive the steel bars to move by starting the steel bar conveying component on the side of the right electrode 2, so that the two steel bars can be accurately butted.

[0042] After the butt welding of the steel bars is completed, by starting the synchronous conveying motor 15 in the steel bar conveying component arranged on the side of the left electrode 1 away from the right electrode 2, the steel bars in the other steel bar conveying component can be moved out by the rotation of the conveying roller 4. When butt welding a batch of steel bars, by setting the movement trajectories between each electrical component, the steel bars to be welded can be loaded only on one side of one of the steel bar conveying components, and the butt welding operation of the steel bars can be continuously carried out.

[0043] In the present disclosure, when actually driving the two synchronous conveying motors 15 in each group of steel bar conveying components, the same signal needs to be used for synchronous driving.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
