[0042] The vertical plate 6 is fixed to the left side of the top wall of the bottom plate 1. The upper end of the vertical plate 6 is rotatably mounted with a steel pipe clamping assembly 7. The left side of the vertical plate 6 is equipped with a driving assembly 8 for driving the steel pipe clamping assembly 7 to rotate;

[0043] The support assembly 9 is fixed on the top wall of the base plate 1 and is located directly below the rolling groove assembly 5 .

[0044] In this embodiment, the first hydraulic cylinder 4 is used to drive the grooving assembly 5 to move downward to perform grooving operations. The number of grooves and the groove spacing of the grooving assembly 5 can be adjusted. It has a wide range of applications and high grooving efficiency. The steel pipe clamping assembly 7 can clamp steel pipes of different sizes, and can select internal clamping or external clamping according to the diameter of the steel pipe, that is, external clamping is selected when the diameter of the steel pipe is small, and internal clamping is selected when the diameter of the steel pipe is large.

[0045] Example 2

[0046] like Figures 2 to 5 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes:

[0047] The groove rolling assembly 5 includes a U-shaped plate 51 . A limiting groove 52 is formed through the middle of the U-shaped plate 51 . A plurality of groove rolling mechanisms 53 are installed in the limiting groove 52 .

[0048] The groove rolling mechanism 53 includes a slider 531, which is slidably mounted in the limiting groove 52. Two mounting plates 532 are symmetrically fixed to the bottom end of the slider 531, and a threaded column 534 is fixed to the top wall of the slider 531.

[0049] A rolling groove cam 533 is rotatably mounted between the bottoms of the two mounting plates 532;

[0050] A washer 535 is sleeved on the threaded column 534 , and a nut 536 is screwed onto the upper end of the threaded column 534 .

[0051] In this embodiment, the number of grooves and the spacing between grooves in the grooving assembly 5 are adjustable, providing a wide range of applications and high grooving efficiency. To adjust the number of grooves or the spacing between grooves, the nut 536 is rotated upward until the grooving mechanism 53 can be smoothly moved. The corresponding number of grooving mechanisms 53 is then selected and placed on the bottom plate of the U-shaped plate 51. The spacing between adjacent grooving mechanisms 53 is adjusted as needed, and the nut 536 is then re-tightened. The grooving assembly 5 in this embodiment can roll multiple grooves simultaneously, significantly improving grooving efficiency.

[0052] The steel pipe clamping assembly 7 includes a cylindrical block 71, which is rotatably mounted on the upper end of the vertical plate 6 through a bearing. A mounting groove 72 is formed in the cylindrical block 71, and a bidirectional screw 73 is rotatably mounted in the mounting groove 72.

[0053] Screw blocks 74 are screwed onto both sides of the bidirectional screw 73, and a connecting shaft 77 is fixed to one end of the bidirectional screw 73;

[0054] The side walls of the two screw blocks 74 are symmetrically mounted with connecting rods 75;

[0055] The other end of the connecting rod 75 is rotatably connected to a clamping rod 76;

[0056] One end of the connecting shaft 77 passes through the cylindrical block 71 through a bearing and is fixed with a knob 78.

[0057] The outer wall of the cylindrical block 71 is symmetrically provided with sliding grooves 79 , and the clamping rod 76 is slidably installed in the corresponding sliding grooves 79 . A through groove 710 is provided between the sliding grooves 79 and the mounting groove 72 , and the connecting rod 75 is movably installed in the through groove 710 .

[0063] Two supporting rollers 93 are symmetrically mounted on the top of the mounting frame 92 for rotation.

[0064] In this embodiment, the steel pipe clamping assembly 7 is capable of clamping steel pipes of different sizes, and can select internal or external clamping according to the diameter of the steel pipe. When it is necessary to clamp a large-diameter steel pipe, one end of the steel pipe is placed on the outside of the clamping rod 76, and then the knob 78 is turned. The knob 78 drives the bidirectional screw 73 to rotate through the connecting shaft 77. The bidirectional screw 73 drives the two screw blocks 74 away from each other. The screw blocks 74 drive the clamping rod 76 to move outward through the connecting rod 75 until the clamping rod 76 clamps the inner wall of the steel pipe. When performing the grooving operation, the switch of the drive motor 81 is turned on. The drive motor 81 drives the cylindrical block 71 to rotate through the driving gear 82 and the outer gear ring 83, and then drives the steel pipe to rotate, cooperating with the grooving assembly 5 to perform the grooving operation on one end of the steel pipe. The support assembly 9 is used to support the roller groove position of the steel pipe. After the steel pipe clamping assembly 7 fixes the steel pipe, the second hydraulic cylinder 91 is controlled to extend until the two support rollers 93 are in contact with the bottom wall of the steel pipe to complete the support of the steel pipe.
