[0037] Example 1, please refer to Figures 1-4, this embodiment provides a device for assisting in the welding of cold-formed steel, including: a bottom plate 1; a rectangular frame 3, which is arranged on the top of the bottom plate 1; a chute 4, which is opened on the inner side of the rectangular frame 3; an electric skateboard 5; the electric skateboard 5 is slidably connected inside the chute 4; a mounting plate 61 is fixedly connected to the bottom of the electric skateboard 5, a motor 62 is fixedly connected to the outer wall of the mounting plate 61, a ratchet wheel 63 is fixedly connected to the output end of the motor 62, a disc 64 is rotatably connected to the outer wall of the mounting plate 61, an annular groove 65 is opened inside the disc 64, a pawl 66 is hinged inside the annular groove 65. By setting the cooperation of the ratchet wheel 63 and the pawl 66, the ratchet wheel 63 can drive the disc 64 to rotate when rotating counterclockwise. An L-shaped plate 67 is fixedly connected to the outer wall of the disc 64, a C-shaped plate 68 is fixedly connected to the outer wall of the L-shaped plate 67, a mounting shaft 69 is rotatably connected inside the C-shaped plate 68, a reciprocating lead screw 610 is fixedly connected to the outer wall of the ratchet wheel 63, and the reciprocating lead screw 610 is used to realize the left and right reciprocating movement of the connecting rod A611. A connecting rod A611 is threadedly connected to the outer wall of the reciprocating lead screw 610, the other end of the connecting rod A611 is fixedly connected to a rectangular frame 612, a rotating block 613 is fixedly connected to one end of the mounting shaft 69, and a sliding shaft 614 is fixedly connected to the outer wall of the rotating block 613. The sliding shaft 614 is slidably connected inside the rectangular frame 612. A telescopic rod 615 is fixedly connected to the outer wall of the disc 64, and the other end of the telescopic rod 615 is fixedly connected to the connecting rod A611. The telescopic rod 615 is used to limit the movement range of the connecting rod A611, so that it can only realize the left and right reciprocating movement. An electric telescopic column 2 is fixedly connected to the upper end of the bottom plate 1, the rectangular frame 3 is fixedly connected to the top of the electric telescopic column 2, and the electric telescopic column 2 is used to adjust the height of the welding machine 10. A welding machine 10 is fixedly sleeved on the outer wall of the mounting shaft 69. A blower 11 is fixedly connected to the upper end of the bottom plate 1 through a fixed seat, and a wind force adjusting mechanism 7 is assembled outside the blower 11. An electric slide rail assembly 12 is arranged on the upper end of the bottom plate 1, and the electric slide rail assembly 12 includes a horizontal electric slide rail and a vertical electric slide rail. The horizontal electric slide rail is arranged on the upper end of the bottom plate 1, the vertical electric slide rail is slidably connected to the upper end of the horizontal electric slide rail, and a clamping plate 13 is fixedly connected to the upper end of the vertical electric slide rail.

[0038] During use, first place the workpiece to be welded between the two clamping plates 13. Then start the horizontal electric slide rail to drive the clamping plates 13 on both sides of the workpiece to move towards the middle until the workpiece is clamped. When it is necessary to adjust the front and rear inclination angles of the welding machine 10, start the motor 62 to drive the ratchet wheel 63 to rotate counterclockwise. At this time, under the action of the pawl 66 hinged in the annular groove 65 inside the disc 64, the disc 64 will be driven to rotate counterclockwise at the same time. At this time, the disc 64 will drive the U-shaped plate 68 to rotate through the L-shaped plate 67. Furthermore, the mounting shaft 69 inside the U-shaped plate 68 will also rotate accordingly, so that the welding machine 10 can rotate accordingly. At the same time, the telescopic rod 615 outside the disc 64 will drive the connecting rod A611 and the disc 64 that are threadedly connected to rotate at the same time. At this time, since the ratchet wheel 63, the disc 64, the reciprocating lead screw 610, and the connecting rod A611 can rotate at the same time, the connecting rod A611 threadedly connected to the outside of the reciprocating lead screw 610 will not move. Then the front and rear angle adjustment of the welding machine 10 is achieved. When it is necessary to adjust the working inclination angle of the welding machine 10, start the motor 62 to drive the ratchet wheel 63 to rotate clockwise. At this time, the pawl 66 will not drive the disc 64 to rotate. At the same time, the ratchet wheel 63 will drive the reciprocating lead screw 610 to rotate. Then the connecting rod A611 threadedly connected to its outer wall will move under the restriction of the telescopic rod 615. Then the rectangular frame 612 will be driven to move. Then the sliding connection in the rectangular frame 612 will change its position to the side while sliding inside it. Furthermore, the sliding shaft 614 will drive the mounting shaft 69 to rotate through the rotating block 613. Then the mounting shaft 69 can be driven to swing left and right, so that the left and right angle adjustment of the welding machine 10 can be achieved. After the adjustment is completed, start the electric skateboard 5 to drive the welding machine 10 to move to the upper end of the welding position. Then start the electric telescopic column 2 to drive the rectangular frame 3 to descend, so that the welding machine 10 descends to perform welding operations.

[0039] Embodiment 2, please refer to Figures 1-6, on the basis of Embodiment 1, the wind force adjusting mechanism 7 includes a vertical rod 71. The vertical rod 71 is fixedly connected to the outer wall of the L-shaped plate 67. A moving groove A72 is formed inside the inner side of the electric skateboard 5. A hydraulic chamber A73 is fixedly connected to the outer wall of the electric skateboard 5. A hydraulic rod A74 is slidably connected inside the hydraulic chamber A73. One end of the hydraulic rod A74 is fixedly connected to a moving block 75. A hydraulic chamber B76 is fixedly connected to the outer wall of the fan 11. A hydraulic rod B715 is slidably connected inside the hydraulic chamber B76. The other end of the hydraulic rod B715 is fixedly connected to a moving plate 78. A guiding groove 712 is formed on the outer wall of the moving plate 78. An activity groove 79 is formed at the upper end of the air outlet pipe of the fan 11. A stopper 710 is slidably connected inside the activity groove 79. The upper end of the stopper 710 is fixedly connected to a guide shaft 711. The guide shaft 711 is slidably connected inside the guiding groove 712. A connecting hose 77 is fixedly connected between the hydraulic chamber A73 and the hydraulic chamber B76. A moving groove B713 is formed on the inner wall of one side chute 4. The hydraulic chamber A73 is slidably connected to the moving groove B713. A spring A714 is fixedly connected to the inner wall of the moving groove A72. The other end of the spring A714 is fixedly connected to the moving block 75. The spring A714 is used to reset the moving block 75.

[0040] During use, the fan 11 blows the surface of the workpiece to be welded through the air outlet pipe, so as to ensure the cleanliness of the welding surface. At the same time, during welding, the flying debris can be blown to the collection assembly. After welding is completed, the electric skateboard 5 is returned to the initial position. At this time, the motor 62 is also started, and the L-shaped plate 67 is rotated in the same way as in Embodiment 1. When the L-shaped plate 67 rotates, the vertical rod 71 at its upper end will also rotate accordingly. When it rotates a certain distance, it will contact the moving block 75, and then the moving block 75 can be pushed to move inside the moving groove A72, and then the hydraulic rod A74 can be pushed into the hydraulic chamber A73. Then, under the action of the connecting hose 77, the hydraulic rod B715 inside the hydraulic chamber B76 will move outwards, thus pushing the moving plate 78 to move at the upper end of the air outlet pipe of the fan 11. Since the guide shaft 711 is slidably connected inside the guiding groove 712, and at the same time, the stopper 710 at the bottom of the guide shaft 711 is slidably connected inside the activity groove 79. Then when the moving plate 78 moves, due to the design of the direction of the guiding groove 712, the position of the guide shaft 711 inside the guiding groove 712 will move from the middle to both sides, thereby driving the stopper 710 to move to both sides inside the activity groove 79, and then the blocking surface of the air outlet pipe of the fan 11 can be made smaller, and then the wind force adjustment of the air outlet can be realized. Then, after welding is completed, the larger waste chips and residues can be blown into the collection assembly. It realizes pre-welding cleaning by blowing with a small wind before and during welding, avoiding excessive wind force that may cause sparks to fly everywhere during the welding process. At the same time, after welding, the large wind can be used to process the waste chips that are difficult to blow.

[0041] Example 3, please refer to Figures 1-7 , on the basis of Example 1, a debris collection component 8 is assembled on the outer wall of the moving block 75. The debris collection component 8 includes a collection frame 81. The collection frame 81 is fixedly connected to the upper end of the bottom plate 1. An arc-shaped slag retaining plate 82 is arranged on the side of the collection frame 81. A connecting rod B83 is fixedly connected to the outer wall of the moving block 75. The other end of the connecting rod B83 is fixedly connected to a pushing block 84. A connecting plate 85 is fixedly connected to the bottom of the electric skateboard 5. A through hole is formed in the outer wall of the connecting plate 85, and a moving rod 86 is slidably connected inside the through hole. Two ends of the moving rod 86 are respectively fixedly connected to a movable block 87 and a cross plate 88. A knocking ball 89 is fixedly connected to the bottom of the cross plate 88. A spring B810 is fixedly connected between the connecting plate 85 and the movable block 87. The spring B810 is used to make the movable block 87 be in a position higher than the pushing block 84 when the pushing block 84 is not subjected to the thrust exerted by the movable block 87. The elastic force of the spring A714 is much greater than that of the spring B810. The contact surface between the pushing block 84 and the movable block 87 is set as an inclined surface.

[0042] During use, firstly, the wind will blow the waste chips and residues during and after welding to the inner wall of the arc-shaped slag retaining plate 82. At the same time, because the length of the vertical rod 71 is limited, when the vertical rod 71 pushes the moving block 75 to move a certain distance, the contact surface between the vertical rod 71 and the moving block 75 changes from the side to the top, and then the restriction on the moving block 75 is released. At this time, under the action of the spring A714, the moving block 75 will be pushed to reset quickly. Furthermore, the moving block 75 will drive the pushing block 84 to move backward through the connecting rod B83. Since the contact surface between the pushing block 84 and the movable block 87 is an inclined surface, when the pushing block 84 moves backward, it will drive the movable block 87 to move downward. Then the movable block 87 will drive the moving rod 86 at the bottom to move downward. Then the moving rod 86 will drive the cross plate 88 to move downward, so that the knocking ball 89 at the bottom of the cross plate 88 will knock on the arc-shaped slag retaining plate 82, and the waste slag collected inside it can fall along the inner wall of the arc-shaped slag retaining plate 82 into the interior of the collection frame 81.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
