DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] The present utility model provides a technical solution: As Figures 1 to 4As shown in the figure, in this embodiment, a circular sawing machine for cutting welded pipes includes a frame 1. A mounting frame 2 is fixedly installed on the top of the frame 1, and a circular sawing machine body 3 is rotatably installed on the top of the mounting frame 2. One end of the frame 1 is fixedly installed with a V-shaped support frame 4 for carrying the welded pipe. A fixed rod 5 is installed at the end of the frame 1 away from the V-shaped support frame 4. A V-shaped rotating frame 6 for carrying the cut welded pipe is rotatably installed at the top of the fixed rod 5. The V-shaped rotating frame 6 rotates as the circular sawing machine body 3 rises. A positioning plate 7 is slidably installed at one end of the V-shaped rotating frame 6. By placing the welded pipe inside the V-shaped support frame 4 and the V-shaped rotating frame 6 and adjusting the distance between the V-shaped rotating frame 6 and the positioning plate 7, one end of the welded pipe can be abutted against one side of the positioning plate 7, so as to adjust the length of the cut welded pipe. After cutting, rotate the circular sawing machine body 3 to reset, which will synchronously drive the V-shaped rotating frame 6 to rotate and drive the cut welded pipe inside the V-shaped rotating frame 6 to be discharged, and the operation is convenient.

[0022] As Figures 1 to 4 shown, a pull rod 8 is rotatably installed on one side of the circular sawing machine body 3 through a pin. A fixed block 9 is fixedly installed at the bottom of the V-shaped rotating frame 6. A connecting shaft 10 is rotatably installed at the bottom end of the fixed block 9. A connecting rod 11 is rotatably installed at the end of the connecting shaft 10 away from the fixed block 9. A positioning rod 12 is slidably installed up and down at the end of the connecting rod 11 away from the connecting shaft 10. A guide rod 13 is fixedly installed on one side of the top of the positioning rod 12. A guide groove 14 is opened at the end of the pull rod 8 away from the circular sawing machine body 3, and the guide groove 14 is slidably connected with the guide rod 13.

[0023] By holding the handle on the circular sawing machine body 3 and controlling the rotation of the circular sawing machine body 3, the circular sawing machine body 3 can cut the welded pipe. After cutting, rotate the circular sawing machine body 3 in the reverse direction. When the circular sawing machine body 3 is almost rotated to the final angle, the guide groove 14 at the bottom end of the pull rod 8 will contact the guide rod 13 and lift the guide rod 13, which will drive the positioning rod 12 installed with the guide rod 13 to rise. Through the connection of the connecting shaft 10 and the connecting rod 11 to the fixed block 9 and the positioning rod 12, the V-shaped rotating frame 6 will be driven to rotate, and the cut welded pipe inside the V-shaped rotating frame 6 will be discharged.

[0024] As Figures 1 to 4 shown, a fixed cylinder 15 is fixedly installed on the upper surface of the frame 1 corresponding to the position of the positioning rod 12. The positioning rod 12 is slidably installed inside the fixed cylinder 15. A return spring 16 is fixedly installed at the bottom of the positioning rod 12, and the bottom end of the return spring 16 is fixedly connected with the inner bottom end of the fixed cylinder 15.

[0025] After discharging the cut welded pipe, by slightly rotating the circular sawing machine body 3, the V-shaped rotating frame 6 will be driven to rotate to the initial position under the pulling of the return spring 16 on the positioning rod 12 for resetting the rotation of the V-shaped rotating frame 6.

[0026] As Figures 1 to 4 shown, a resisting rod 17 is fixedly installed on the upper surface of the frame 1 corresponding to the position of the V-shaped rotating frame 6.

[0027] The final reset angle of the V-shaped rotating frame 6 can be controlled.

[0028] As Figures 1 to 4 shown, sliding rods 18 are symmetrically and fixedly installed on one side of the positioning plate 7, and sliding holes 19 are formed in the V-shaped rotating frame 6 corresponding to the positions of the sliding rods 18. The sliding holes 19 are slidably connected with the sliding rods 18.

[0029] When adjusting the distance between the V-shaped rotating frame 6 and the positioning plate 7, the sliding of the sliding rods 18 inside the sliding holes 19 can be controlled to support the positioning plate 7.

[0030] As Figures 1 to 4 shown, a sliding groove 20 is formed on one side of the V-shaped rotating frame 6 close to the sliding hole 19. A sliding block 21 is slidably installed inside the sliding groove 20. A clamping block 22 is fixedly installed on one side of the sliding block 21. Claw slots 23 are formed at equal intervals on the outer side of the sliding rod 18. The claw slots 23 are clamped with the clamping block 22. One end of the sliding block 21 is fixedly installed with a positioning spring 24. The end of the positioning spring 24 away from the sliding block 21 is fixedly connected with the bottom end of the V-shaped rotating frame 6 corresponding to the sliding groove 20.

[0031] By pulling the clamping block 22 to slide along the sliding groove 20 to slide the clamping block 22 out of the inside of the claw slot 23, at this time the positioning spring 24 is in a stretched state. Then pull the positioning plate 7 to adjust the distance between the V-shaped rotating frame 6 and the positioning plate 7. Then cancel pulling the clamping block 22. The pulling of the sliding block 21 by the positioning spring 24 will drive the clamping block 22 to be clamped into the inside of the claw slot 23. Then abut one end of the welded pipe against one side of the positioning plate 7, and the length of the cut welded pipe can be adjusted.

[0032] The present utility model provides a circular sawing machine for cutting welded pipes. The specific working principle is as follows:

[0033] When the device is in use, place the welded pipe inside the V-shaped support frame 4 and the V-shaped rotating frame 6. By pulling the clamping block 22 to slide along the sliding groove 20 to slide the clamping block 22 out of the inside of the claw slot 23, at this time the positioning spring 24 is in a stretched state. Then pull the positioning plate 7 to adjust the distance between the V-shaped rotating frame 6 and the positioning plate 7. Then cancel pulling the clamping block 22. The pulling of the sliding block 21 by the positioning spring 24 will drive the clamping block 22 to be clamped into the inside of the claw slot 23. Then abut one end of the welded pipe against one side of the positioning plate 7, and the length of the cut welded pipe can be adjusted;

[0034] By holding the handle on the circular saw body 3 and controlling the rotation of the circular saw body 3, the circular saw body 3 can cut the welded pipe. During the rotation of the circular saw body 3, the guide groove 14 at the bottom end of the pull rod 8 installed on the circular saw body 3 will slide on the outside of the guide rod 13 and will not squeeze the guide rod 13. After cutting, rotate the circular saw body 3 in the reverse direction. When the circular saw body 3 is about to rotate to the final angle, the guide groove 14 at the bottom end of the pull rod 8 will contact the guide rod 13 and lift the guide rod 13, which will drive the positioning rod 12 installed with the guide rod 13 to slide along the inside of the fixed cylinder 15, controlling the positioning rod 12 to rise. Through the connection of the connecting shaft 10 and the connecting rod 11 to the fixed block 9 and the positioning rod 12, the V-shaped rotating frame 6 will be driven to rotate, driving the cut welded pipe inside the V-shaped rotating frame 6 to be discharged. At this time, the return spring 16 is in a stretched state. After discharging, by slightly rotating the circular saw body 3, under the pulling of the return spring 16 on the positioning rod 12, the V-shaped rotating frame 6 will be driven to rotate to the initial position for the reset of the rotation of the V-shaped rotating frame 6.
