First embodiment: The fixed end of the hydraulic rod 41 is fixed to the top surface of the inner side of the fixing frame 2, and the fixing frame 2 is L-shaped. The telescopic end of the No. 1 electric telescopic rod 51 passes through the outside of the fixing frame 2 and is fixed to the push plate 5; the two push plates 5 correspond to a plurality of steel pipes 10 respectively, such as from the drawings in the specification. Figure 2 As shown in the figure, there are eight arc-shaped grooves 31 on the bearing plate 3, so one push plate 5 corresponds to four steel pipes 10; when the four steel pipes 10 are cut, the cutting blade 61 moves toward the fifth steel pipe 10, and the pressing plate 4 moves upward, and then the telescopic end of a group of No. 1 electric telescopic rods 51 drives the push plates 5 corresponding to the four cut steel pipes 10 to move, so that the four steel pipes 10 continue to move toward the cutting blade 61, so that the next cutting point continues to correspond to the cutting blade 61; when the cutting blade 61 moves to the top of the fifth steel pipe 10, the push plate 5 is restored, and the pressing plate 4 moves downward to continue to press the steel pipe 10 down and fix it; four steel pipes 10 are a group, and a group After the steel pipe 10 is cut, the cutting blade 61 moves toward another group of steel pipes 10, and the pressure plate 4 moves upward, which can move the push plate 5 corresponding to the group of steel pipes 10 that has been cut, and push the steel pipe 10 to improve the cutting efficiency of the steel pipe 10; the setting of the connecting piece 52 can increase the contact area between the push plate 5 and the end of the steel pipe 10, so as to better push the steel pipe 10. The connecting piece 52 is fixed to the push plate 5 by bolts. After replacing the supporting plate 3 with arc grooves 31 of different depths, the connecting piece 52 can be removed and replaced with an adapted connecting piece 52; the total number of connecting pieces 52 on the two push plates 5 is the same as the number of arc grooves 31 on the supporting plate 3.
[0018] Second embodiment: There are two pressing plates 4, and two groups of hydraulic rods 41. The telescopic ends of the two groups of hydraulic rods 41 are respectively fixed to the top of the pressing plates 4; accordingly, one pressing plate 4 corresponds to four steel pipes 10, so when the four steel pipes 10 are cut, the corresponding pressing plate 4 moves upward, and then the corresponding pushing plate 5 moves toward the four steel pipes 10, so as to push the four cut steel pipes 10; it will not affect the cutting operation of the other four steel pipes 10.
[0019] like Figure 1 As shown, the side of the cutting blade 61 away from the push plate 5 is provided with a limit plate 8 corresponding to the end of the steel pipe 10. A vertical rod 82 is fixed to the bottom of the limit plate 8. A second electric telescopic rod 81 is fixed to the base 1, and the telescopic end of the second electric telescopic rod 81 is connected to the vertical rod 82. When the steel pipe 10 is placed in the arc-shaped groove 31, the second electric telescopic rod 81 is started to cause the vertical rod 82 to drive the limit plate 8 to move toward the steel pipe 10. After adjusting the position of the limit plate 8, the push plate 5 pushes the steel pipe 10 to move.

The transfer process is simple and fast, and the steel pipes 10 are prevented from being squeezed against each other.
[0022] When in use, after the steel pipe 10 is placed in the arc groove 31, the No. 1 electric telescopic rod 51 is started to move the push plate 5. After the push plate 5 contacts the end of the steel pipe 10, the steel pipe 10 is pushed toward the cutting blade 61, so that the cutting point of the steel pipe 10 moves to the outside of the arc groove 31 and is located directly below the cutting blade 61. The push plate 5 is restored; then the telescopic end of the hydraulic rod 41 drives the pressing plate 4 to move downward, pressing down and fixing the top of the steel pipe 10 outside the arc groove 31. The extension of the automatic telescopic rod 62 The shrinking end drives the motor 6 to move downward, and the motor 6 drives the cutting blade 61 to rotate. After the cutting blade 61 contacts the steel pipe 10, it starts to cut the steel pipe 10; after the steel pipe 10 is cut, the cutting blade 61 and the pressing plate 4 move upward to restore, and the push plate 5 moves toward the steel pipe 10 and continues to push the steel pipe 10. After the steel pipe 10 is pushed, the push plate 5 is restored, and the pressing plate 4 continues to move downward to fix the steel pipe 10, and then the above operation is repeated to cut the steel pipe 10.
