Description

Technical Field

[0002] Pressure welding refers to a welding method in which the weldment undergoes plastic deformation under heated or unheated conditions, so that the surface atoms of the two weldments form metal bonds to connect them. Pressure welding of rebar can make the connection between the two rebars tighter. This type of pressure device usually has the following characteristics: it can accurately adjust the applied pressure according to different welding processes and weldment requirements, maintain pressure stability during the welding process, avoid adverse effects of pressure fluctuations on welding quality, and achieve high-precision control of pressure to meet the needs of precision welding.

[0003] When pressure welding rebars, workers need to use tools to clamp the two rebars. Workers use welding guns and other tools to make the connection between the two rebars reach a thermoplastic state. When the connection between the two rebars reaches the thermoplastic state, workers apply pressure to the weld and maintain it for a period of time. During the welding operation, the temperature of the weld is high, and it is difficult to keep the two rebars clamped for a long time, which results in the two rebars not being tight enough after welding and easy to fall off.

[0020] The cleaning mechanism 67 includes a cleaning plate 671, a through hole 674 is provided at the axis of the cleaning plate 671, the inner wall of the through hole 674 is slidably connected to the side of the guide rod 68, and the side of the cleaning plate 671 is evenly provided with a clearance groove 672.

[0022] The specific workflow is as follows: During operation, the two threaded steel bars to be welded are placed on the clamping component 4 and their positions are adjusted, and then the two threaded steel bars are welded by the welding component 3. At the same time, the collecting component 6 is opened during welding to collect the welding slag and waste gas generated during welding. When the two threaded steel bars are welded, the pressurizing component 5 is opened to pressurize the threaded steel bars. By pulling the clamping plate 44 upward, the clamping plate 44 moves upward on the connecting shaft 43 to disengage from the clamping seat 41, so that the two threaded steel bars are placed in the clamping groove 42.

When the pressure plate 54 moves toward the threaded steel bar, the pressure plate 54 simultaneously drives the scraper 55 to move on the bottom plate 2, so that the impurities remaining on the bottom plate 2 can be pushed down into the collecting component 6; When welding threaded steel bars, the suction machine 61 is turned on, and the suction force generated by the suction machine 61 allows the welding slag and waste gas generated during the welding work to enter the storage box 65 through the filter plate 610, so that the storage box 65 collects the welding slag generated during welding. The suction force generated by the suction machine 61 allows the rotating mechanism 66 to rotate on the filter plate 610, so as to avoid the welding slag entering the storage box 65 from accumulating on the filter plate 610, thereby causing the filter plate 610 to be blocked. The waste gas generated during welding can enter the connecting pipe 62 through the guide pipe 63, so as to filter and discharge the waste gas generated during welding. At the same time, the suction force generated by the suction machine 61 allows the cleaning mechanism 67 to move in the guide pipe 63, so that the cleaning mechanism 67 cleans the inner wall of the guide pipe 63. Through the suction force of the air suction machine 61, the cleaning plate 671 moves on the guide rod 68 through the through hole 674, so that the cleaning plate 671 drives the bent plate 673 to clean the inner wall of the guide pipe 63, thereby preventing the exhaust gas from being discharged through the guide pipe 63 for a long time, thereby preventing impurities from remaining in the inner wall of the guide pipe 63. At the same time, by evenly opening the side of the cleaning plate 671 with the clearance groove 672, the exhaust gas entering the guide pipe 63 can pass normally, avoiding interference with the transportation of the exhaust gas. When the suction machine 61 continues to work, the rotating plate 661 rotates on the filter plate 610 through the rotating shaft 662, so that the brush 663 cleans the side of the filter plate 610, thereby preventing impurities entering the storage box 65 from being adsorbed on the filter plate 610 and causing the exhaust gas to be unable to pass normally. At the same time, when the rotating plate 661 rotates on the filter plate 610, the bent rod 665 rotates in the square groove 664 due to the action of centrifugal force, so that the bent rod 665 drives the bent hook 666 to rotate in the storage box 65, so that it can impact the welding slag sucked into the storage box 65, so that the welding slag moves to the surrounding inner wall of the storage box, thereby preventing a large amount of welding slag from accumulating above the filter plate 610.
