After the cutting is completed, the steel pipe that has been cut is taken out, and the storage bin 20 is taken out from the surface of the sliding groove 16. Before the saw disk 11 is cut, the horizontal plate 18 is used to push the inside of the storage bin 20 so that one end of the steel pipe located at the upper end of the roller 21 is horizontal. When cutting, the steel pipe will roll on the surface of the roller 21 under the cutting action of the saw disk 11. When the roller 21 rolls, the rotating bearing 23 installed inside the roller 21 rotates. Under the rotation action of the roller 21 and the rotating bearing 23, the evenness of the cross-section of the steel pipe after cutting can be guaranteed. Cutting three steel pipes at a time can speed up the cutting efficiency. Placing the roller 21 inside the semicircular groove 24 can limit the position, prevent the roller 21 from deviating from the position, and ensure the accuracy of the steel pipe during the cutting process.

[0026] like Figure 1-Figure 4 As shown, leveling components 15 are fixedly installed on both side surfaces of the storage bin 20, and a threaded rod 19 passes through the interior of the leveling component 15. A horizontal plate 18 is fixedly installed at one end of the threaded rod 19. After the steel pipe is placed in the gap of the roller 21, the threaded rod 19 passing through the interior of the leveling component 15 is pushed toward the storage bin 20, driving the horizontal plate 18 to be pushed inward, so that one end of the three steel pipes can be horizontal and maintained in a horizontal position, thereby ensuring the accuracy of cutting.

A fixed rod 6 is fixedly installed inside the support frame 8, and a slitting assembly 9 is rotatably installed on the fixed rod 6. The rotating disk 7 fixedly installed on the upper surface of the assembly plate 2 can make the slitting assembly 9 located above rotate at an angle. The existence of the support frame 8 can fix the fixed rod 6 inside it. The fixed rod 6 can increase the installation carrier for the slitting assembly 9, so that the slitting assembly 9 can rotate up and down on the surface of the fixed rod 6, which is convenient for the saw disk 11 to descend to cut the steel pipe.

[0029] like Figure 1-Figure 4 As shown, a motor 14 is fixedly installed on the lower surface of the slitting component 9, and a transmission rod 5 is rotatably installed on the output end of the motor 14.

An installation groove 10 is provided on the lower surface of the slitting component 9. After the steel pipe is placed under the saw disk 11, the motor 14 is turned on, and the motor 14 drives the transmission rod 5 to rotate. During the rotation, the transmission rod 5 will cause the saw disk 11 installed on one end of the transmission rod 5 to rotate. When the saw disk 11 rotates, the second lifting handle 12 is pressed downward so that the saw disk 11 can contact the steel pipe below. After one cutting is completed, the saw disk 11 is pulled upward by the first lifting handle 13 to leave the contact surface of the steel pipe, which makes it convenient for the operator to lift the slitting component 9 up and down.

After the cutting is completed, the cut steel pipe is taken out, and the storage bin 20 is taken out from the surface of the sliding groove 16. Before the saw disc 11 cuts, the horizontal plate 18 is used to push the steel pipe to the lower end of the saw disc 11. The internal push of the storage bin 20 makes one end of the steel pipe located at the upper end of the roller 21 horizontal. When cutting, the steel pipe will roll on the surface of the roller 21 under the cutting action of the saw disc 11. When the roller 21 rolls, the rotary bearing 23 installed inside the roller 21 rotates. Under the rotation action of the roller 21 and the rotary bearing 23, the evenness of the cut surface of the steel pipe after cutting can be guaranteed.

The rotating disk 7 fixedly installed on the upper surface of the assembly plate 2 can make the slitting assembly 9 located above rotate at an angle. The existence of the support frame 8 can fix the fixing rod 6 inside it, and the fixing rod 6 can increase the installation carrier for the slitting assembly 9, so that the slitting assembly Component 9 can rotate up and down on the surface of the fixed rod 6, which makes it convenient for the saw disc 11 to descend and cut the steel pipe. By turning on the motor 14, the motor 14 drives the transmission rod 5 to rotate. During the rotation of the transmission rod 5, the saw disc 11 installed at one end of the transmission rod 5 rotates. When the saw disc 11 rotates, the second lifting handle 12 is pressed downward so that the saw disc 11 can contact the steel pipe below. After a cut is completed, the saw disc 11 is pulled up by the first lifting handle 13 to leave the contact surface of the steel pipe, which makes it convenient for the operator to lift the cutting component 9 up and down.
