[0002] In daily life, metal products can be seen everywhere. These metal products will be damaged by oxidation due to contact with air, especially some metal pipes used to transport liquids. The economic loss of replacing these metal pipes as a whole after the occurrence of bad spots is large. The general treatment method is to cut off the part at the bad spot and then weld the replacement part. During the welding process, a clamping device for metal pipe welding is needed to fix and support the metal pipe to ensure the quality and efficiency of welding. The existing clamping device needs to frequently adjust the clamping mechanism when welding pipes of different sizes. The common clamping mechanism is to achieve clamping by turning the screw. This means that when welding pipes with large size differences, it is necessary to turn the screw for a long time to adjust the clamping mechanism, making the operation cumbersome and inconvenient.

[0005] As a preferred technical solution of the utility model, the pushing component includes a mounting frame, two mounting frames are fixedly connected to the top of the bracket, and the two mounting frames are symmetrically arranged.
[0006] As a preferred technical solution of the utility model, the pushing component also includes half nut one, half nut one and half nut two are slidingly connected in the two installation frames, tension springs are connected between half nut one and half nut two and the installation frames, half nut one and half nut two located on the same installation frame are a group, and half nut one and half nut two located on the same installation frame are in contact.
[0007] As a preferred technical solution of the utility model, the pushing component also includes a pushing screw, and the two sliding clamps are rotatably connected to the pushing screw on one side close to the mounting frame, and the half nut one and the half nut two are threadedly connected to the pushing screw.
[0008] As a preferred technical solution of the utility model, the pushing component also includes a transmission frame, the transmission frame is slidably connected to the bracket, two clamping blocks are fixedly connected to the transmission frame, the two clamping blocks are symmetrically arranged, the clamping blocks are located below the half nut one and the half nut two, a reset spring is connected between the two clamping blocks and the bracket, a foot pedal is fixedly connected to the lower part of the transmission frame, and the foot pedal and the bracket are slidably connected.
[0009] Beneficial effects: 1. The staff first places the two square tubes to be welded on the fixed clamp blocks respectively, and then the staff rotates the push screw, which drives the sliding clamp block to move, so that the sliding clamp block slides toward the fixed clamp block, so that the fixed clamp block and the sliding clamp block clamp the square tube. When the tube to be welded is not a square tube, before welding, the staff rotates the extrusion screw, and the extrusion screw moves toward the sliding clamp block to clamp the pipe. After welding, the extrusion screw is rotated in the opposite direction, and the extrusion screw is reset. Then the staff removes the welded pipe, and repeats this process to achieve welding and clamping of pipes of different shapes.
[0010] 2. When welding pipes of different sizes, the staff only needs to step on the foot pedal, which drives the clamping block to descend, compresses the reset spring, and gradually reduces the extrusion force of the clamping block on half nut one and half nut two. The tension spring resets, and the tension spring drives half nut one and half nut two to slide away from each other. At this time, the push screw and half nut one and half nut two are separated. In this way, the staff only needs to push the push screw to drive the sliding clamp to move, and the staff does not need to turn the push screw to move the sliding clamp, making the operation easier and faster.

DETAILED DESCRIPTION
[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.
[0018] Embodiment 1: A clamping device for metal pipe welding, such as Figures 1-5 As shown, a bracket 1 is included, and two fixed clamping blocks 2 are fixedly connected to the bracket 1, and the two fixed clamping blocks 2 are symmetrically arranged. The lower parts of the two fixed clamping blocks 2 are fixedly connected to slide rails 3, and the two slide rails 3 are fixedly connected to the bracket 1. The two slide rails 3 are slidably connected to sliding clamping blocks 4, and the sliding clamping blocks 4 can slide on the slide rails 3. The sides of the two fixed clamping blocks 2 away from the sliding clamping blocks 4 are threadedly connected to extrusion screws 5, and the extrusion screws 5 are used for extruding pipes. The bracket 1 is provided with a pushing component.
[0019] The pushing component includes a mounting frame 6. Two mounting frames 6 are fixedly connected to the top of the bracket 1, and the two mounting frames 6 are symmetrically arranged.
[0020] The pushing component also includes a half nut 1 7, and the two installation frames 6 are both slidably connected with half nut 1 7 and half nut 2 71. A tension spring 8 is connected between the half nut 1 7 and the half nut 2 71 and the installation frame 6. The half nut 1 7 and the half nut 2 71 located on the same installation frame 6 are a group, and the half nut 1 7 and the half nut 2 71 located on the same installation frame 6 are in contact.
[0021] The pushing component also includes a pushing screw 9, and the two sliding clamps 4 are rotatably connected to the pushing screw 9 on one side close to the mounting frame 6. The half nut 1 7 and the half nut 2 71 are threadedly connected to the pushing screw 9, and the rotation of the screw 9 can drive the sliding clamps 4 to slide.
[0022] At first, half nut one 7 and half nut two 71 are clamped by clamping block 11, pushing screw 9 is located between half nut one 7 and half nut two 71, and tension spring 8 is in a stretched state. During work, the staff first places the two square tubes to be welded on the fixed clamping block 2 respectively, and then the staff rotates the pushing screw 9, and the pushing screw 9 drives the sliding clamping block 4 to move, so that the sliding clamping block 4 slides in the direction close to the fixed clamping block 2. When the fixed clamping block 2 and the sliding clamping block 4 clamp the square tube, the staff stops rotating the pushing screw 9. After welding, the staff rotates the pushing screw 9 in the opposite direction, and the pushing screw 9 drives the sliding clamping block 4 to move in the opposite direction. Then the staff removes the welded square tube. When the welding is not a square tube, the staff repeats the above steps and also needs to rotate the extruding screw 5. Before welding, the staff rotates the extruding screw 5, and the extruding screw 5 moves in the direction close to the sliding clamping block 4 to clamp the pipe. After welding, the extruding screw 5 is rotated in the opposite direction, and the extruding screw 5 is reset. Then the staff removes the welded pipe, and so on and so forth to achieve welding clamping of pipes of different shapes.
[0023] Embodiment 2: Based on embodiment 1, Figures 2-5 As shown, the pushing component also includes a transmission frame 10, and the transmission frame 10 is slidably connected to the bracket 1. Two clamping blocks 11 are fixedly connected to the transmission frame 10, and the two clamping blocks 11 are symmetrically arranged. The clamping blocks 11 are located below the half nut 1 7 and the half nut 2 71. The clamping blocks 11 are used to clamp the half nut 1 7 and the half nut 2 71. A reset spring 12 is connected between the two clamping blocks 11 and the bracket 1, and the reset spring 12 is used to drive the clamping blocks 11 to reset. A foot pedal 13 is fixedly connected to the lower part of the transmission frame 10, and the foot pedal 13 is slidably connected to the bracket 1.
[0024] When it is necessary to weld pipes of different specifications and sizes, the staff only needs to step on the foot pedal 13, the foot pedal 13 drives the clamping block 11 to descend, the reset spring 12 is compressed, the extrusion force of the clamping block 11 on the half nut 1 7 and the half nut 2 71 is gradually reduced, the tension spring 8 is reset, and the tension spring 8 drives the half nut 1 7 and the half nut 2 71 to slide away from each other, at this time, the pushing screw 9 and the half nut 1 7 and the half nut 2 71 are disengaged, so that the staff only needs to push the pushing screw 9 to drive the sliding clamp 4 to move, and the staff does not need to turn the push screw 9. The screw rod 9 is moved to move the sliding clamp 4, making the operation easier and faster. After the sliding clamp 4 is close to the pipeline, the staff no longer steps on the pedal 13, and the reset spring 12 is reset. The reset spring 12 drives the clamping block 11 to rise, and the half nut 1 7 and the half nut 2 71 are squeezed by the clamping block 11, and the half nut 1 7 and the half nut 2 71 slide in the opposite direction towards each other, and the tension spring 8 is stretched, and the half nut 1 7 and the half nut 2 71 contact with the pushing screw rod 9 again. Then the staff rotates the pushing screw rod 9 again to make the sliding clamp 4 approach the pipeline to clamp the pipeline.
