[0019] Preferably, casters are installed at all four corners of the bottom of the aluminum frame.

[0020] Preferably, an installation component is provided between the tabletop and both the first limiting plate and the second limiting plate. The installation component includes an installation groove, an installation block, and a bolt.

[0042] The punch 10 is installed on one end of the stamping guide rod 9.

[0043] The nut fixing baffle 5 is installed on the surface of the table top 1.

[0044] The second limiting plate 4 and the first limiting plate 3 are respectively installed on the surface of the table top 1 and located on the left and right sides of the nut fixing baffle 5.

[0045] The guide rod cylinder 6 is installed on the surface of the table top 1 and located on the rear side of the nut fixing baffle 5.

[0046] The bottom of the table top 1 is provided with an aluminum frame 2.

[0047] The rear side of the surface of the table top 1 is provided with a hydraulic gauge 13.

[0048] Four corners of the bottom of the aluminum frame 2 are provided with casters 14.

[0049] The table top 1 is fixed on the aluminum frame 2, the first limiting plate 3 and the second limiting plate 4 are installed on the table top, the nut fixing baffle 5 is pressed and can slide forward and backward along the gap below the first limiting plate 3 and the second limiting plate 4, the rear end of the nut fixing baffle 5 is connected with a guide rod cylinder 6, the guide rod cylinder 6 moves forward and backward through air pressure, a connecting rod fixing support 7 is installed below the table top 1, an open hole support block 8 is transversely installed on the connecting rod fixing support 7, a stamping guide rod 9 is vertically installed in the support through the support block, so that it can only move in the upward and downward directions through the open hole, a punch 10 is fixed on the end of the stamping guide rod 9 through bolts, the lower half of the connecting rod fixing support 7 at the lower end of the stamping guide rod 9 is communicated with a rear hydraulic cylinder 11, the hydraulic cylinder 11 is communicated with a left gas storage cylinder 12, the hydraulic cylinder is driven by air pressure, and the hydraulic cylinder 11 is communicated with a hydraulic gauge 13 pressure gauge above the table top 1, four casters 14 are fixed below the aluminum frame 2, which facilitates movement.

[0050] Before operation, ventilate the equipment and retract the nut fixing baffle 5. During operation, insert the nut and ferrule into the bent steel pipe in sequence. To ensure sealing, apply an appropriate amount of sealant to the inner ring of the ferrule. Then, align the entire assembly with the punch 10 and place it upright. Keep the ferrule and nut in the correct position and the steel pipe vertical. Then, move the nut fixing baffle 5 forward until the steel pipe is fully inserted into the groove. At this point, the baffle is directly above the nut, thus restricting the nut from moving upward. Step on the foot pedal to move the air storage cylinder, pushing the punching guide rod 9 connected to the hydraulic cylinder 11 upward. At this point, the punch 10 drives the steel pipe ferrule upward, while the nut cannot move upward. The ferrule deforms under pressure during this process, thus fixing it to the steel pipe. When the pressure gauge reading stabilizes, stop the hydraulic cylinder from pushing upward. At this point, the ferrule is stably and firmly fixed to the steel pipe.
