Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel bar processing technology, and in particular to a steel bar butt welding device for uniform welding. Background Technology
[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete. Their cross-section is circular, and sometimes square with rounded corners. They include plain round bars, ribbed bars, and twisted bars. Reinforcing bars for reinforced concrete refer to straight or coiled steel used for reinforcing concrete. Their shape is divided into plain round bars and deformed bars. When processing reinforcing bars, welding equipment is required to weld them.
[0003] During the rebar splicing process, the lack of suitable limiting and guiding devices can easily cause the rebars to tilt or shift, making it impossible to guarantee horizontal and vertical movement. This not only increases the difficulty of welding but may also lead to uneven welding, resulting in problems such as incomplete welds or incomplete penetration. Utility Model Content
[0004] The purpose of this invention is to provide a steel bar butt welding device that produces uniform welds, thereby solving at least one of the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rebar butt welding device for uniform welding, comprising an I-shaped frame and two rebars, and further comprising:
[0006] A docking mechanism is provided, which is mounted on a U-shaped frame. The docking mechanism includes a bidirectional threaded rod mounted on the U-shaped frame. The docking mechanism is used to clamp and dock the reinforcing bars to ensure the stability of the reinforcing bars during docking.
[0007] A limiting mechanism is provided, which is mounted on a U-shaped frame. The limiting mechanism includes a hollow box mounted on the U-shaped frame. The limiting mechanism is used to position two steel bars to ensure that the distance between the two steel bars is equal and that they can make contact and dock simultaneously when they approach each other.
[0008] Preferably, the docking mechanism includes a bidirectional threaded rod that is rotatably mounted on a C-shaped frame. A drive motor is fixedly mounted on the right side of the C-shaped frame. The output shaft of the drive motor is fixedly connected to the bidirectional threaded rod. Two internal threaded plates are threaded onto the bidirectional threaded rod.
[0009] Preferably, a limiting slide rod is fixedly installed on the C-shaped frame, and the limiting slide rod passes through the two internal threaded plates and is slidably connected to the two internal threaded plates.
[0010] Preferably, the two internally threaded plates are respectively provided with circular groove 1, and the left and right sides of the shaped frame are respectively provided with circular groove 2, and the two steel bars pass through the corresponding circular groove 2 and circular groove 1 respectively.
[0011] Preferably, each of the two internally threaded plates has a screw threadedly installed inside it, the bottom ends of the two screws extend to the outside of the internally threaded plates, and the top ends of the two screws are rotatably installed with rotating plates, the tops of the two rotating plates contacting the two reinforcing bars respectively.
[0012] Preferably, L-shaped limiting rods are fixedly installed at the bottom of the two rotating plates, and limiting grooves are opened in the two C-shaped frames. The two limiting grooves are respectively connected to two circular grooves. Two strip-shaped limiting plates are slidably installed in the two limiting grooves. The tops of the two strip-shaped limiting plates are respectively in contact with two steel bars, and the two L-shaped limiting rods slide through the two strip-shaped limiting plates.
[0013] Preferably, the limiting mechanism includes a hollow box fixedly installed on the inner wall of the bottom of the C-shaped frame, a limiting spring fixedly installed on the inner wall of the bottom of the hollow box, a limiting slider fixedly installed on the top of the limiting spring, and the top of the limiting slider slidingly extending outside the hollow box.
[0014] Preferably, a triangular block is fixedly installed on the top of the limiting slider, and arc-shaped contact blocks are fixedly installed on the sides of the two internal threaded plates that are close to each other. The ends of the two arc-shaped contact blocks that are close to each other and the ends of the two reinforcing bars that are close to each other are in contact with the triangular block.
[0015] The beneficial effects of this utility model are as follows:
[0016] In this utility model:
[0017] 1. First, place the two reinforcing bars into the two circular slots (one and two) respectively, and push them closer together until they both contact the triangular blocks. At this point, the triangular blocks will cause the two reinforcing bars to be symmetrically and equidistantly distributed. Then, rotate the two screws. The screws will move upward, causing the rotating plate to move closer to the reinforcing bars. Correspondingly, the rotating plate will move the L-shaped limiting rod, which in turn will move the strip limiting plate synchronously. At this point, the strip limiting plate and the rotating plate will rise synchronously to contact and clamp the two reinforcing bars, thus ensuring that the reinforcing bars can move horizontally and vertically without misalignment, and enabling accurate positioning and fixation of the reinforcing bars.
[0018] 2. After fixing the reinforcing bars, start the drive motor. The drive motor rotates forward, driving the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the two internal threaded plates to move away from each other. The internal threaded plates will then drive the two reinforcing bars held by the rotating plates to move away from each other. At this time, the end faces of the two reinforcing bars that are close to each other can be heated. After the end faces of the two reinforcing bars are heated, reverse the drive motor. The drive motor will drive the two internal threaded plates on the bidirectional threaded rod to move closer to each other. The internal threaded plates will then drive the two arc-shaped contact blocks to move closer to each other. After the arc-shaped contact blocks contact the triangular blocks, the triangular blocks will descend under the action of the inclined plane of the triangular blocks. At this time, the triangular blocks will drive the limit slider to descend. At this time, the limit spring will be compressed and deformed. At this time, there will be no obstruction between the reinforcing bars. As the drive motor continues to rotate, the heated end faces of the two reinforcing bars will contact each other and complete the docking. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figure 1-5The illustrated rebar butt welding device includes a U-shaped frame 1 and two rebars 107, and further includes: a butt welding mechanism, which is mounted on the U-shaped frame 1 and includes a bidirectional threaded rod 101 mounted on the U-shaped frame 1, used for clamping and butt welding the rebars 107 to ensure the stability of the rebars 107 during butt welding; and a limiting mechanism, which is mounted on the U-shaped frame 1 and includes a hollow box 2 mounted on the U-shaped frame 1, used for positioning the two rebars 107 to ensure that the distance between the two rebars 107 is equal and that they can simultaneously contact and butt weld when they approach each other. The butt welding mechanism includes the bidirectional threaded rod 101, which is rotatably mounted through the U-shaped frame 1. A drive motor 102 is fixedly mounted on the right side of the U-shaped frame 1, and the output shaft of the drive motor 102 is fixedly connected to the bidirectional threaded rod 101. Two internal threaded plates 103 are threaded onto the bidirectional threaded rod 101. A limiting slide rod 104 is fixedly installed on the C-shaped frame 1. The limiting slide rod 104 passes through two internally threaded plates 103 and is slidably connected to the two internally threaded plates 103. Circular groove 105 is opened on each of the two internally threaded plates 103. Circular groove 2 106 is opened on the left and right sides of the C-shaped frame 1, respectively. Two reinforcing bars 107 pass through the corresponding circular groove 2 106 and circular groove 105. Screws 108 are threaded into each of the two internally threaded plates 103. The bottom ends of the two screws 108 extend outside the internally threaded plates 103, and rotating plates 109 are rotatably installed on the top ends of the two screws 108. The tops of the two rotating plates 109 contact the two reinforcing bars 107, respectively. L-shaped limiting rods 110 are fixedly installed at the bottom of the two rotating plates 109 respectively. Limiting grooves 111 are opened in the two C-shaped frames 1 respectively. The two limiting grooves 111 are connected to the two circular grooves 106 respectively. Two strip-shaped limiting plates 112 are slidably installed in the two limiting grooves 111 respectively. The tops of the two strip-shaped limiting plates 112 are in contact with the two steel bars 107 respectively. The two L-shaped limiting rods 110 slide through the two strip-shaped limiting plates 112 respectively.
[0027] First, place the two reinforcing bars 107 into the two circular slots 105 and 106 respectively, and push them closer together so that both bars 107 contact the triangular blocks 203. At this time, the triangular blocks 203 will make the two reinforcing bars 107 symmetrically and equidistantly distributed. Then, rotate the two screws 108. The screws 108 will move upward, which will drive the rotating plate 109 to move closer to the reinforcing bars 107. Correspondingly, the rotating plate 109 will drive the L-shaped limiting rod 110 to move, which will drive the strip limiting plate 112 to move synchronously. At this time, the strip limiting plate 112 and the rotating plate 109 will rise synchronously to contact and clamp the two reinforcing bars 107, thereby ensuring that the reinforcing bars 107 can move horizontally and vertically without misalignment, so that the reinforcing bars 107 can be accurately positioned and fixed.
[0028] The limiting mechanism includes a hollow box 2 fixedly installed on the inner wall of the bottom of the U-shaped frame 1. A limiting spring 201 is fixedly installed on the inner wall of the bottom of the hollow box 2. A limiting slider 202 is fixedly installed on the top of the limiting spring 201. The top of the limiting slider 202 slides out of the hollow box 2. A triangular block 203 is fixedly installed on the top of the limiting slider 202. Arc-shaped contact blocks 204 are fixedly installed on the sides of the two internally threaded plates 103 that are close to each other. The ends of the two arc-shaped contact blocks 204 that are close to each other and the ends of the two steel bars 107 that are close to each other are in contact with the triangular block 203.
[0029] After fixing the reinforcing bars 107, start the drive motor 102. The drive motor 102 rotates forward, driving the bidirectional threaded rod 101 to rotate. The bidirectional threaded rod 101 drives the two internal threaded plates 103 to move away from each other. The internal threaded plates 103 will then drive the two reinforcing bars 107, which are held by the rotating plate 109, to move away from each other. At this time, the end faces of the two reinforcing bars 107 that are close to each other can be heated. After the end faces of the two reinforcing bars 107 are heated, reverse the drive motor 102. The drive motor 102 will then drive the bidirectional threaded rod 101... Two internally threaded plates 103 approach each other, which in turn causes two arc-shaped contact blocks 204 to approach each other. After contacting the triangular block 203, the arc-shaped contact block 204 will cause the triangular block 203 to descend under the action of the inclined surface of the triangular block 203. At this time, the triangular block 203 will cause the limiting slider 202 to descend. At this time, the limiting spring 201 will undergo compression deformation. At this time, there will be no obstruction between the steel bars 107. As the drive motor 102 continues to rotate, the heated ends of the two steel bars 107 will contact each other to complete the docking.
[0030] The working principle of the steel bar butt welding equipment with uniform welding provided by this utility model is as follows:
[0031] First, place the two reinforcing bars 107 into the two circular slots 105 and 106 respectively, and push the two reinforcing bars 107 closer together so that both reinforcing bars 107 contact the triangular blocks 203. At this time, the triangular blocks 203 will make the two reinforcing bars 107 symmetrically and evenly distributed. Then, rotate the two screws 108. The screws 108 will move upward and drive the rotating plate 109 to move closer to the reinforcing bars 107. Correspondingly, the rotating plate 109 will drive the L-shaped limiting rod 110 to move. The L-shaped limiting rod 110 will drive the strip limiting plate 112 to move synchronously. At this time, the strip limiting plate 112 and the rotating plate 109 will rise synchronously to contact and clamp the two reinforcing bars 107, thereby ensuring that the reinforcing bars 107 can move horizontally and vertically without misalignment, so that the reinforcing bars 107 can be accurately positioned and fixed.
[0032] After fixing the reinforcing bars 107, start the drive motor 102. The drive motor 102 rotates forward, driving the bidirectional threaded rod 101 to rotate. The bidirectional threaded rod 101 drives the two internal threaded plates 103 to move away from each other. The internal threaded plates 103 will then drive the two reinforcing bars 107, which are held by the rotating plate 109, to move away from each other. At this time, the end faces of the two reinforcing bars 107 that are close to each other can be heated. After the end faces of the two reinforcing bars 107 are heated, reverse the drive motor 102. The drive motor 102 will then drive the bidirectional threaded rod 101... Two internally threaded plates 103 approach each other, which in turn causes two arc-shaped contact blocks 204 to approach each other. After contacting the triangular block 203, the arc-shaped contact block 204 will cause the triangular block 203 to descend under the action of the inclined surface of the triangular block 203. At this time, the triangular block 203 will cause the limiting slider 202 to descend. At this time, the limiting spring 201 will undergo compression deformation. At this time, there will be no obstruction between the steel bars 107. As the drive motor 102 continues to rotate, the heated ends of the two steel bars 107 will contact each other to complete the docking.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
