[0025] The directional rod 5 is movable through the interior of the positioning groove 6, and a "V"-shaped groove is provided inside the positioning seat 12;

[0026] There are two groups of cylinders 15, and the cylinders 15 are symmetrically distributed on both sides of the hydraulic cylinder 18;

[0027] Specifically, if Figure 1 and Figure 3 As shown, open the cylinder 15, and use the first telescopic rod 13 to drive the bottom positioning seat 12 to move downward. At the same time, the bottom directional rod 5 will be guided in the positioning groove 6, so that the "V"-shaped groove inside the positioning seat 12 can be used to position the steel pipe on the movable platform 7. Because the positioning seats 12 are symmetrically distributed on both sides of the pressing seat 23, it is convenient to move the steel pipe after flattening one end of the steel pipe, so as to continue to position and flatten the other end, making it more suitable.

[0028] Embodiment 2: The four corners at the bottom of the workbench 1 are fixedly connected with legs 2, and the movable platform 7 has the same length as the workbench 1;

[0029] A handle 10 is fixedly connected to one side of the movable platform 7, and a connecting block 4 is fixedly connected to the front and rear ends of the bottom of the movable platform 7. The connecting block 4 is embedded in the inner part of the slide groove 3 and can slide.

[0030] The positioning hole 8 is movably connected with a positioning bolt 9, and the movable platform 7 is detachable from the workbench 1 through the positioning bolt 9;

[0031] Specifically, if Figure 1 and Figure 2 As shown, when flattening, the movable platform 7 and the workbench 1 can be fixed in advance by using the positioning bolts 9. When the steel pipe needs to be taken later, the positioning bolts 9 are opened and the movable platform 7 is moved on the workbench 1 by using the handle 10, making it easier to take.

[0032] Embodiment 3: A movable groove 16 is provided at the top of the top plate 14, a hydraulic cylinder 18 is fixedly installed at the top of the top plate 14, a second telescopic rod 19 is fixedly connected to the bottom end of the hydraulic cylinder 18, the bottom end of the second telescopic rod 19 passes through the interior of the top plate 14 and is fixedly connected to the bottom plate 20, and positioning rods 17 are fixedly connected to both sides of the top of the bottom plate 20;

[0033] A pressure seat 23 is provided at the bottom end of the bottom plate 20, and connecting rods 21 are fixedly connected at the four corners of the top of the pressure seat 23. Reserved holes 24 are provided at the four corners of the top of the bottom plate 20, and the connecting rods 21 pass through the inside of the reserved holes 24. The outside of the connecting rods 21 is movably connected with a locking nut 22, and the pressure seat 23 is detachable from the bottom plate 20 through the locking nut 22;

[0034] Specifically, if Figure 1 and Figure 4As shown, open the hydraulic cylinder 18 and use the second telescopic rod 19 to press the pressure seat 23 downward. At this time, the top positioning rod 17 can move inside the movable groove 16, so as to flatten the bottom steel pipe. When the pressure seat 23 needs to be replaced later, the locking nut 22 can be screwed open to disengage the connecting rod 21 on the top of the pressure seat 23 from the reserved hole 24, and a new pressure seat 23 can be replaced, making replacement and installation more convenient.

[0035] Working principle: When the utility model is used, first, the cylinder 15 is opened, and the first telescopic rod 13 can be used to drive the bottom positioning seat 12 to move downward. At the same time, the bottom directional rod 5 will be guided in the positioning groove 6, so that the "V"-shaped groove inside the positioning seat 12 can be used to position the steel pipe on the movable platform 7. Because the positioning seats 12 are symmetrically distributed on both sides of the pressure seat 23, it is convenient to flatten one end of the steel pipe and then move the steel pipe to continue positioning and flattening the other end. After that, the hydraulic cylinder 18 is opened, and the pressure seat 23 is pressed downward by the second telescopic rod 19. At this time, the top The positioning rod 17 at the bottom can move inside the movable groove 16, so as to flatten the steel pipe at the bottom. When flattening, the movable platform 7 and the workbench 1 can be fixed in advance by the positioning bolts 9. When the steel pipe needs to be taken later, the positioning bolts 9 are opened, and the movable platform 7 is moved on the workbench 1 by using the handle 10, so that it is more labor-saving when taking it. Finally, when the pressure seat 23 needs to be replaced, the locking nut 22 can be screwed open, so that the connecting rod 21 at the top of the pressure seat 23 is detached from the reserved hole 24, and a new pressure seat 23 can be replaced, which makes replacement and installation more convenient.
