Cutting multiple pipes requires multiple cutting operations, and the pipes need to be held by hand. The pipes are prone to shaking during cutting, which affects the stability of the cutting process. Therefore, a pipe cutting device for building water and electricity construction is proposed to solve the above problems. Utility Model Content

The pressing plate 10 is further locked by the fixing bolt 11 to control the clamping firmness of the clamping head 30 on the pipe, thereby facilitating the stable clamping and fixing of the pipe.

[0026] The drive mechanism 14 includes an L-shaped frame 15, with a lifting beam 16 on the inner side of the L-shaped frame 15.

The sliding seat 20 is provided with a sliding groove adapted to the slide rail 19. The bottom surface of the sliding seat 20 is fixedly connected to both ends of the saw blade 13. The connecting column 21 is provided with a slot for the saw blade 13 to be embedded. The saw blade 13 is fixedly installed to the connecting column 21 by a mounting bolt (31). Both the connecting column 21 and the saw blade 13 are provided with a round hole for the mounting bolt 31 to pass through. The end of the mounting bolt 31 is threaded with a nut.

[0028] The rear end of the sliding seat 20 is fixedly connected to a push groove 22. The lifting beam 16 is rotatably connected to a disc 23 corresponding to the push groove 22. The eccentric part of the disc 23 is fixedly connected to a toggle pin 24. The toggle pin 24 is movably connected in the push groove 22 and is adapted to the push groove 22.

[0029] A motor 25 is fixedly installed on the outer side of the lifting beam 16 corresponding to the disc 23. The output end of the motor 25 is fixedly connected to a first synchronous pulley 26. A second synchronous pulley 27 is provided on the outer side of the first synchronous pulley 26. The second synchronous pulley 27 is concentrically arranged with the disc 23.

[0031] The lifting beam 16 is lowered by the electric push rod 18, and the saw blade 13 is driven to reciprocate by the motor 25, thereby creating a downward cutting effect and thus cutting the pipe.

[0032] Both the electric actuator 18 and the motor 25 are externally connected to a power source and a switch.

[0033] The working principle of this utility model is as follows: In use, place the pipe to be cut into the corresponding pipe clamping groove 6, and use a measuring tape to determine the cutting length in conjunction with the saw blade 13. Then, press the fixing clamp 5 onto the placement seat 3, so that the connecting plate 7 fits against the support seat 2. At this point, the locking bolt 9 is located within the notch 8. Tighten the locking bolt 9 further, so that the fixing clamp 5 and the placement seat 3 clamp the pipe through the pipe clamping groove 6. Then, further tighten the fixing bolt 11, and squeeze the toothed extrusion plate 10, so that the clamping head 30 further clamps the pipe. This allows the pipe to be stably clamped and fixed. At this time, the electric push rod 18 and the motor 25 can be driven. The motor 25 drives the first synchronous wheel 26 to rotate. The first synchronous wheel 26 drives the second synchronous wheel 27 to rotate through the synchronous belt 28. The second synchronous wheel 27 drives the disc 23 to rotate synchronously. The disc 23 drives the push groove 22 to move through the actuating pin 24. The push groove 22 drives the sliding seat 20 to slide on the slide rail 19, thereby realizing the reciprocating movement of the saw blade 13. At the same time, the electric push rod 18 drives the lifting beam 16 to descend, thereby realizing the pipe cutting process.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
