Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of rebar welding technology, and more specifically, to a rebar butt welding device that produces uniform welds. Background Technology

[0002] In many engineering fields such as building construction and bridge construction, steel bar connection is of paramount importance, and steel bar welding equipment is widely used as a key tool to achieve efficient and reliable connections.

[0003] The existing steel bar butt welding equipment mainly consists of a welding transformer, electrodes, a feeding mechanism, and control elements. The welding transformer is responsible for providing the current required for welding. The electrodes are divided into left and right electrodes, which are used to conduct current and press the ends of the steel bars together. The feeding mechanism is used to push the steel bars to move during welding, realizing the melting and extrusion process. The control elements control the welding process according to a specific program.

[0004] However, existing rebar welding equipment suffers from insufficient precision and stability during actual welding processes due to the use of pneumatic or hydraulic cylinders for the feeding mechanism. This is particularly true during the conveying process, where precise control of the rebar's feeding speed and position is difficult. This can lead to uneven heating at the weld joint. In large construction projects, the large number and size of rebars can cause over-welding, resulting in brittle rebars and reduced overall strength. Alternatively, incomplete penetration can occur, significantly weakening the connection strength. Furthermore, the long-term storage of the rebars or their poor surface finish at the factory can affect the current conduction efficiency between the two rebars after welding, further impacting the weld strength and uniformity. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a steel bar butt welding device that produces uniform welds, thereby solving the problem mentioned in the background art that the existing steel bar butt welding devices have poor steel bar conveying accuracy and stability during steel bar butt welding, which easily affects the steel bar welding efficiency.

[0006] According to one aspect, at least one embodiment of this disclosure provides a butt welding device for uniformly welding reinforcing bars, including two left electrodes and two right electrodes, and further including a butt welding frame, an electrode support portion, and a reinforcing bar conveying assembly. The electrode support portion is provided in two symmetrical arrangements, each electrode support portion having a left electrode and a right electrode. The right electrode is slidable toward the left electrode.

Two sets of reinforcing bar conveying assemblies are provided, symmetrically arranged on the butt welding frame, and the electrode support portion is located between the two reinforcing bar conveying assemblies. The rebar conveying assembly includes a clamping conveying section. There are two clamping conveying sections arranged symmetrically. One clamping conveying section is located on the welding frame, and the other clamping conveying section is located on the welding frame via a clamping adjustment section. The clamping conveying section is provided with several conveying rollers for conveying rebars and several clamping blocks for fixing rebars.

[0007] Based on the aforementioned scheme, the electrode support portion includes a U-shaped support plate, a U-shaped adjusting plate, a limiting rod, and an adjusting spring. The U-shaped support plate is disposed on the welding frame or the electrode adjusting portion. The left electrode is mounted on the U-shaped support plate. The U-shaped adjusting plate passes through and slides on one side of the U-shaped support plate. The limiting rod passes through and slides on the U-shaped support plate. One end of the limiting rod is connected to one end of the U-shaped adjusting plate. The adjusting spring is disposed between the U-shaped support plate and the U-shaped adjusting plate, and the limiting rod is located inside the adjusting spring.

[0008] To facilitate the clamping of the reinforcing bars by the left and right electrodes, the electrode adjustment unit includes an electrode adjustment cylinder and an electrode pressure sensor. The electrode adjustment cylinder is installed on the welding frame, and the electrode pressure sensor is installed on the output end of the electrode adjustment cylinder. The detection end of the electrode pressure sensor is connected to the U-shaped support plate.

[0009] As a preferred technical solution of this disclosure, the clamping and conveying unit includes a conveying frame, a feeding frame, universal couplings, a synchronous conveying motor, a conveying shaft, and a conveying worm gear. The conveying frame is mounted on the welding frame or the clamping and adjusting unit. Several feeding frames are provided, arranged in pairs in a straight line on the conveying frame. Each feeding frame corresponds to a conveying roller, and the conveying roller is rotatably mounted on the feeding frame. Several universal couplings are provided, each corresponding to a pair of feeding frames, and rotatably mounted on the conveying frame. Both ends of each universal coupling are connected to one end of the corresponding conveying roller. The synchronous conveying motor... The machine is installed at one end of the conveyor frame. The conveyor shaft is rotatably mounted on the conveyor frame. One end of the conveyor shaft is connected to the output end of the synchronous conveyor motor. There are several conveying worm gears, each corresponding to a universal coupling. The conveying worm gears are mounted on the universal couplings. There are several conveying worms, each mounted on the conveyor shaft. The conveying worms correspond to the conveying worm gears and mesh with them. There are several clamping cylinders, arranged in pairs in a line on the conveyor frame. Each clamping cylinder corresponds to a clamping block, which is mounted on the output end of the clamping cylinder.

[0010] To improve the stability of steel bar conveying, the two feeding racks, arranged in pairs, are tilted symmetrically, and a conveying cavity is formed between the corresponding two conveying rollers.

[0011] To facilitate the fixing and straightening of the reinforcing bars, the two clamping cylinders, arranged in pairs, are tilted symmetrically, and a clamping cavity is formed between the corresponding two clamping blocks.

[0012] Based on the aforementioned scheme, the clamping and adjusting unit includes a material feeding and adjusting cylinder and a material feeding pressure sensor. The material feeding and adjusting cylinder is installed on the welding frame, and the material feeding pressure sensor is installed on the output end of the material feeding and adjusting cylinder. The detection end of the material feeding pressure sensor is connected to one end of the conveying frame.

[0013] To facilitate the inspection of the welded ends of the reinforcing bars, a detection cylinder is installed on one side of the welding frame, and a position detection sensor capable of detecting the ends of the reinforcing bars is installed at the output end of the detection cylinder.

[0014] To improve the uniformity of steel bar welding, the end of the welding frame away from the detection cylinder is also equipped with a cleaning part that can grind the welded end of the steel bar. The cleaning part includes a cleaning cylinder, a cleaning frame, a cleaning motor, and a cleaning grinding wheel. The cleaning cylinder is installed on one side of the welding frame, the cleaning frame is set on the output end of the cleaning cylinder, the cleaning motor is installed on the cleaning frame, and the cleaning grinding wheel is set on the output end of the cleaning motor.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, by setting up an electrode bearing part and an electrode adjusting part, and in conjunction with an electrode pressure sensor, it is possible not only to accurately control the electrode spacing and welding pressure, ensuring uniform current distribution during the welding process, making the steel bar welding stronger and more uniform, and improving the welding quality and stability, but also to ensure that the right electrode slides toward the left motor under the compression of the adjusting spring, ensuring the stability of the welding process. 2. In this disclosure, by using two sets of symmetrically arranged steel bar conveying components, in conjunction with multiple conveying rollers, it can not only adapt to the conveying of steel bars of different specifications, but also form a conveying and clamping cavity by using two sets of inclined and symmetrically arranged feeding racks and clamping cylinders, which can stably convey steel bars and improve the efficiency and accuracy of steel bar conveying. 3. In this disclosure, by setting an edge-cleaning section on one side of the welding frame, when butt welding the reinforcing bars, the edge-cleaning cylinder is first activated to drive the edge-cleaning grinding wheel to move between the left and right electrodes. Then, the reinforcing bars to be welded are placed on the two reinforcing bar conveying assemblies respectively. The reinforcing bars are moved by the reinforcing bar conveying assemblies so that the welding ends of the two reinforcing bars contact the two ends of the edge-cleaning grinding wheel respectively. This not only allows for precise positioning of the welding ends of the reinforcing bars, but also allows the edge-cleaning grinding wheel to be rotated by activating the edge-cleaning motor, which can grind the welding edge of the reinforcing bars to remove impurities on the welding surface or to flatten the welding surface. After grinding the welding surface of the reinforcing bars, the positions of the left and right electrodes are adjusted to clamp the reinforcing bars. Then, the reinforcing bar conveying assembly on the right electrode side is activated to move the reinforcing bars so that the two reinforcing bars can be precisely butt-jointed.

[0019] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-9 As shown, it illustrates a uniformly welded rebar butt welding device according to an embodiment of the present disclosure, including two left electrodes 1 and two right electrodes 2, as well as a butt welding frame 3, an electrode support 001 and a rebar conveying assembly.

[0026] Among them, the left electrode 1 and the right electrode 2 are commonly used mechanisms in existing steel bar welding equipment. Their main function is to conduct current to weld steel bars together. In actual welding, a corresponding welding transformer is required to provide a stable current to meet the welding requirements of the steel bars.

[0027] like Figure 5 As shown above, there are two electrode support parts 001, which are arranged symmetrically. Each electrode support part 001 is provided with a left electrode 1 and a right electrode 2. The right electrode 2 can slide toward the left electrode 1. One electrode support part 001 is provided on the welding frame 3, and the other electrode support part 001 is provided on the welding frame 3 through the electrode adjustment part 002.

[0028] The electrode support part 001 includes a U-shaped support plate 6, a U-shaped adjustment plate 7, a limiting rod 8, and an adjustment spring 9. The U-shaped support plate 6 is disposed on the welding frame 3 or the electrode adjustment part 002. The left electrode 1 is mounted on the U-shaped support plate 6. The U-shaped adjustment plate 7 is slidably disposed on one side of the U-shaped support plate 6. The limiting rod 8 is slidably disposed on the U-shaped support plate 6. One end of the limiting rod 8 is connected to one end of the U-shaped adjustment plate 7. The adjustment spring 9 is disposed between the U-shaped support plate 6 and the U-shaped adjustment plate 7. The limiting rod 8 is located inside the adjustment spring 9.

[0029] The electrode adjustment unit 002 includes an electrode adjustment cylinder 10 and an electrode pressure sensor 11. The electrode adjustment cylinder 10 is mounted on the welding frame 3, and the electrode pressure sensor 11 is mounted on the output end of the electrode adjustment cylinder 10. The detection end of the electrode pressure sensor 11 is connected to the U-shaped support plate 6.

[0030] Specifically, starting the electrode adjusting cylinder 10 causes the output end of the electrode adjusting cylinder 10 to drive the motor pressure sensor to move. The movement of the motor pressure sensor drives the U-shaped support plate 6 to move, adjusting the positions of the left electrode 1 and the right electrode 2 so that the two corresponding right electrodes 2 and left electrodes 1 clamp the steel bar. After the two right electrodes 2 clamp the steel bar, the movement of the steel bar will drive the right electrode 2 to move towards the left electrode 1. When the right electrode 2 moves towards the left electrode 1, it will drive the U-shaped adjusting plate 7 to move within the U-shaped support plate 6. The movement of the U-shaped adjusting plate 7 compresses the adjusting spring 9. Under the sliding of the limiting rod 8, the stability of the sliding of the U-shaped adjusting plate 7 is increased to ensure the stability of the movement of the right electrode 2.

[0031] like Figure 6As shown above, the rebar conveying assembly is provided in two sets. The rebar conveying assemblies are symmetrically arranged on the welding frame 3. The electrode bearing part 001 is located between the two rebar conveying assemblies. The rebar conveying assembly includes a clamping conveying part 003. There are two clamping conveying parts 003, which are symmetrically arranged. One clamping conveying part 003 is arranged on the welding frame 3, and the other clamping conveying part 003 is arranged on the welding frame 3 through a clamping adjustment part 004. The clamping conveying part 003 is provided with a number of conveying rollers 4 that can convey rebar and a number of clamping blocks 5 that can fix the rebar.

[0032] The material clamping and conveying unit 003 includes a conveyor 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 conveyor frame 12 is mounted on the welding frame 3 or the material clamping and adjusting unit 004. Several feeding frames 13 are arranged in pairs on the conveyor frame 12, with each feeding frame 13 corresponding to a conveying roller 4. The conveying roller 4 is rotatably mounted on the feeding frame 13. Several universal couplings 14 are arranged in pairs on the conveyor frame 12, with each universal coupling 14 corresponding to a pair of feeding frames 13. The two ends of each universal coupling 14 are connected to one end of the corresponding conveying roller 4. The synchronous conveying motor... 15 is installed at one end of the conveyor frame 12. The conveyor shaft 16 is rotatably mounted on the conveyor frame 12. One end of the conveyor shaft 16 is connected to the output end of the synchronous conveyor motor 15. Several conveyor worm gears 17 are provided. Each conveyor worm gear 17 corresponds to a universal coupling 14. The conveyor worm gear 17 is mounted on the universal coupling 14. Several conveyor worms 18 are provided. Each conveyor worm gear 18 is mounted on the conveyor shaft 16. Each conveyor worm gear 18 corresponds to a conveyor worm gear 17. The conveyor worm gear 18 meshes with the conveyor worm gear 17. Several clamping cylinders 19 are provided. The clamping cylinders 19 are arranged in pairs in a line on the conveyor frame 12. Each clamping cylinder 19 corresponds to a clamping block 5. The clamping block 5 is mounted on the output end of the clamping cylinder 19.

[0033] Specifically, the synchronous conveyor motor 15 is started, and the output end of the synchronous conveyor motor 15 drives the conveyor shaft 16 to rotate. The rotation of the conveyor shaft 16 drives the conveyor worm 18 to rotate, and the rotation of the conveyor worm 18 drives the conveyor worm wheel 17 to rotate. The rotation of the conveyor worm wheel 17 can drive the universal coupling 14 connected to it to rotate. The rotation of the universal coupling 14 can drive the conveyor roller 4 to rotate. When conveying the steel bars, the steel bars come into contact with the conveyor roller 4. The rotation of the conveyor roller 4 drives the steel bars to move. In order to increase the contact friction between the steel bars and the conveyor roller 4, a rubber pad can be covered on the surface of the conveyor roller 4 to improve the stability of steel bar conveying. When the conveyor worm 18 drives the conveyor worm wheel 17 to rotate, the meshing of the conveyor worm 18 and the conveyor worm wheel 17 can achieve a good self-locking effect and improve the stability of steel bar conveying.

[0034] After the steel bars are transported to a specific location, in order to further increase the stability of the steel bars, the clamping cylinder 19 can be activated to drive the clamping block 5 to move. The clamping block 5 contacts the steel bars, which increases the stability of the steel bars. At the same time, the clamping blocks 5, which are arranged in a straight line, can also straighten the steel bars to improve the uniformity of the steel bar joint.

[0035] It should be noted that the two feeding racks 13, which are set up in pairs, are arranged symmetrically at an angle, and a conveying cavity is formed between the two corresponding conveying rollers 4. When conveying steel bars, placing the steel bars in the conveying cavity can further increase the stability of the steel bars.

[0036] The two clamping cylinders 19, which are set up in pairs, are arranged in an inclined and symmetrical manner. A clamping cavity is formed between the two corresponding clamping blocks 5. Specifically, after the conveying roller 4 contacts and squeezes the steel bar, the steel bar can be corrected at multiple angles through the squeezing of the clamping blocks 5, thereby further improving the neatness of the steel bar joint.

[0037] The aforementioned clamping and adjusting unit 004 includes a material adjusting cylinder 20 and a material adjusting pressure sensor 21. The material adjusting cylinder 20 is mounted on the welding frame 3, and the material adjusting pressure sensor 21 is mounted on the output end of the material adjusting cylinder 20. The detection end of the material adjusting pressure sensor 21 is connected to one end of the conveying frame 12.

[0038] Specifically, the material conveying adjustment cylinder 20 is activated, and the output end of the material conveying adjustment cylinder 20 drives the material conveying pressure sensor 21 to move. The movement of the material conveying pressure sensor drives the conveying frame 12 to move, which can make the conveying roller 4 clamp the steel bar. Through the detection of the material conveying pressure sensor 21, the pressure of the conveying roller 4 squeezing the steel bar can be adjusted to prevent the steel bar from slipping between the conveying roller 4 and the conveying roller 4.

[0039] like Figure 8 As shown, a detection cylinder 22 is installed on one side of the welding frame 3. A position detection sensor 23 capable of detecting the end of the reinforcing bar is installed at the output end of the detection cylinder 22. Specifically, when the detection cylinder 22 is activated, 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 detection sensor 23 can detect the position of the welding end of the reinforcing bar, so that the left electrode 1 and the right electrode 2 can precisely clamp the reinforcing bar for butt welding.

[0040] like Figure 9As shown, to further elaborate, the end of the welding frame 3 away from the detection cylinder 22 is also equipped with a cleaning part 005 for grinding the welded end of the steel bar. The cleaning part 005 includes a cleaning cylinder 24, a cleaning frame 25, a cleaning motor 26, and a cleaning grinding wheel 27. The cleaning cylinder 24 is installed on one side of the welding frame 3, the cleaning frame 25 is set on the output end of the cleaning cylinder 24, the cleaning motor 26 is installed on the cleaning frame 25, and the cleaning grinding wheel 27 is set on the output end of the cleaning motor 26.

[0041] Specifically, by setting an edge-cleaning part 005 on one side of the welding frame 3, when butt welding the reinforcing bars, the edge-cleaning cylinder 24 is first started to drive the edge-cleaning grinding wheel 27 to move between the left electrode 1 and the right electrode 2. Then, the reinforcing bars to be welded are placed on the two reinforcing bar conveying assemblies respectively. The reinforcing bar conveying assemblies drive the reinforcing bars to move, so that the welding ends of the two reinforcing bars contact the two ends of the edge-cleaning grinding wheel 27 respectively. This not only allows for precise positioning of the welding ends of the reinforcing bars, but also allows the edge-cleaning grinding wheel 27 to be rotated by starting the edge-cleaning motor 26, which can grind the welding edge of the reinforcing bars to remove impurities on the welding surface or to flatten the welding surface. After grinding the welding surface of the reinforcing bars, the positions of the left electrode 1 and the right electrode 2 are adjusted to clamp the reinforcing bars. Then, the reinforcing bar conveying assembly on the right electrode 2 side is started to drive the reinforcing bars to move, so that the two reinforcing bars can be precisely connected.

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

[0043] In this disclosure, the two synchronous conveying motors 15 in each group of rebar conveying assemblies need to be driven synchronously using the same signal during actual operation.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
