[0036] A plurality of guide grooves 3 are arranged on the guide plate 2, and the guide grooves 3 are communicated with each other. A group of guide moving blocks 36 arranged on the bottom of the support box 7 are arranged in the guide grooves 3. When the shearing part 4 needs to be moved, the part can be pushed by external force. The bending part 5 drives the pipe to be bent. When the 90-degree end formed after the bending needs to be sheared, the shearing part 4 can be pushed to the side of the second motor 57. When the straight pipe needs to be sheared, the shearing part 4 can be pushed to the side of the support column 44 along the guide groove 3 by external force.

In this way, the clamping block 68 pushes the pipe to be clamped, so that the stability of the pipe is increased when the pipe is sheared.

[0038] The detailed use method and effect of the embodiment are as follows:

[0039] The pipe is erected at the V-shaped groove 41, and the pipe is pushed forward to the bending part 5. The first cylinder 24 and the first air rod 23 are driven to produce telescopic movement. The first air rod 23 pulls the top wheel tooth column 22 to move left and right. The end of the top wheel tooth column 22 away from the first air rod 23 is provided with a telescopic column. The other end of the telescopic column is fixed on the fixed column 37. When the top wheel tooth column 22 moves left and right, the telescopic column is pulled to stretch or retract. When the top wheel tooth column 22 moves left and right, the gear I 20 engaged with the top wheel tooth column 22 rotates, thereby driving the gear II 21 on the side to rotate, further driving the gear shaft inserted in the middle of the two gears to rotate, further driving the two holding rods 25 to move. The holding rods 25 clamp and fix the pipe. The third cylinder 45 and the third air rod 46 are driven to produce telescopic movement. The third air rod 46 pulls the moving plate 47 to move. When the moving plate 47 moves to the side of the third cylinder 45, the oval groove 48 pulls the limiting rod 49 to move. The limiting rod 49 moves along with the oval groove 48 arranged obliquely, thereby driving the moving plate 50 to slide to the left. The clamping block 68 at the top edge of the moving plate 50 pushes the limiting block 69 and the stop block 67 to clamp and fix the pipe. The second motor 57 is driven to rotate. The second motor 57 drives the gear III 58 to rotate, thereby driving the gear IV 59 engaged with the side to rotate. The gear IV 59 drives the rotating column 60 at the top to rotate, thereby driving the rotating disc 61 to rotate. The rotating disc 61 rotates, thereby driving the limiting wheel 64 to press the pipe to bend the pipe.

[0040] The shearing part 4 is pushed to the side where shearing is needed. The bent pipe passes through the semicircular clamping groove between the pushing column 13 and the limiting column 14. The second cylinder 26 and the second air rod 27 are driven to produce telescopic movement. The second air rod 27 drives the top plate 17 to move downward. When the pressing column 35 moves downward, the pushing column 13 on the lower side is pressed. The pushing column 13 moves to the right. The pushing column 13 clamps the pipe. The cutter 18 on the upper side passes through the slot 15 to shear the pipe.

[0041] The above specific embodiments can be easily implemented by those skilled in the art in the technical field. However, it should be understood that the present application is not limited to the above specific embodiments. On the basis of the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to realize different technical solutions.
