Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting for hydropower installation, and more specifically, to a pipe cutter for hydropower installation. Background Art

[0002] In the current technological environment, water and electricity installation engineers often use pipe cutters to cut pipes and ensure accurate installation of pipes. These cutters are usually equipped with cutting blades and motors, which undertake the main cutting tasks during operation. Due to their certain mass, these components will generate significant weight pressure during the cutting process, which requires the use of a spring system to provide the necessary rebound force to maintain the balance and precision of the operation. Ideally, these springs should be able to adjust the rebound force they provide according to the specific requirements of the cutting task (such as the thickness or hardness of the cutting material). However, traditional pipe cutter designs often lack this flexibility and cannot adapt to the rebound force requirements under different cutting conditions, which may lead to instability during the cutting process, affect the cutting quality, and even increase equipment wear and shorten service life.

[0003] The limitation of the existing technology is that the design of its spring system is often fixed, which limits the adaptability of the equipment when facing different cutting environments. For example, when cutting thicker or harder materials, a stronger rebound force is required to support the stable operation of the cutting blade; on the contrary, when cutting thinner or softer materials, too strong rebound force may cause unnecessary wear or even damage the material. If the equipment cannot adjust the spring rebound force, it will not only increase the difficulty of work, but also greatly reduce work efficiency and accuracy. Utility Model Content

An adjusting mechanism is arranged on the base 1, and the adjusting mechanism comprises a receiving mechanism, a rotating shaft 2, a fixing plate 3, a spring 4, a fixing mechanism, an inserting sleeve 5, a fixing rod 6, a threaded sleeve 7 and a receiving plate 8.

The fixing plates 3 at the ends are mounted on the base 1, and the receiving plate 8 is mounted on the spring 4.

The fixing mechanism includes a center sleeve 9 and a center rod 10. The center sleeve 9 is installed on the rotating shaft 2, and the center rod 10 is clamped on the center sleeve 9. A fitting disk 101 is provided on the center rod 10, and a hexagonal block 11 is provided on the fitting disk 101. Hexagonal grooves 12 are respectively opened on multiple fixed disks 3, and the hexagonal blocks 11 are clamped in the hexagonal grooves 12.

The limiting ring 14 is pressed on the fitting disk 8, and the fitting disk 8, the limiting sleeve 13 and the limiting ring 14 are respectively coaxially arranged.

[0030] In this embodiment, when it is necessary to cut the pipe, the spring 4 is adjusted according to the different pipes to adjust its rebound force at the same rotation angle. First, a fixing rod 6 of a corresponding length is selected according to the situation, and then the fixing rod 6 is passed through a corresponding number of insertion sleeves 5, and the fixing rod 6 is threadedly connected to the threaded sleeve 7. The spring 4 connected to the fixed disk 3 is in a fixed state. Therefore, only a part of the spring 4 participates in the rotation during rotation, which will change the spring coefficient of the spring 4, thereby adjusting its rebound force. The fixation of the hexagonal block 11 and the receiving plate 8, the fixation of the center rod 10 and the center sleeve 9 ensures the transmission of the rebound force, thereby completing the adjustment process.

[0031] See also Figure 1 , Figure 4 and Figure 5 As an implementation method of a water and electricity installation pipe cutter for a receiving mechanism: the receiving mechanism includes a cutting frame 15 and a motor 16, the rotating shaft 2 is installed on the cutting frame 15, the cutting frame 15 is attached to the base 1, the motor 16 is connected to the cutting frame 15, a cutting blade 17 is provided on the protruding end of the motor 16, an external power supply device is electrically connected to the motor 16, a turntable 18 is rotatably provided on the base 1, and a plurality of scales 19 are opened on the base 1 along the turntable 18, a follower plate 20 is provided on the turntable 18, and the pipe is attached to the follower plate 20.

[0032] More specifically, after adjusting the spring 4, the corresponding pipe is first installed on the turntable 18 and fit on the follower plate 20. Since a scale 19 is provided on the base 1, the turntable 18 indicates on the scale 19. The rotation of the follower turntable 18 can adjust its cutting angle, and then the motor 16 and the cutting disc 17 are rotated downward to cut the pipe, thereby completing the cutting process. The optimal rebound force not only ensures the cutting stability, but also reduces the operator's fatigue.

[0033] In summary, when the overall equipment is in use or running: when it is necessary to cut the pipe, the spring 4 is adjusted according to the different pipes to adjust its rebound force at the same rotation angle. First, the fixed rod 6 of the corresponding length is selected according to the situation, and then the fixed rod 6 is passed through the corresponding number of insertion sleeves 5, and the fixed rod 6 is threadedly connected to the threaded sleeve 7. The spring 4 connected to the fixed disk 3 is in a fixed state. Therefore, only a part of the spring 4 participates in the rotation during rotation, which will change the stiffness coefficient of the spring 4, thereby adjusting its rebound force. The fixation of the hexagonal block 11 and the receiving plate 8, the fixation of the center rod 10 and the center sleeve 9 ensures the transmission of the rebound force, thereby completing the adjustment process.

[0034] After adjusting the spring 4, first install the corresponding pipe on the turntable 18 and fit it on the follower plate 20. Since the base 1 is provided with a scale 19, the turntable 18 indicates on the scale 19. The rotation of the follower turntable 18 can adjust its cutting angle, and then the motor 16 and the cutting disc 17 are rotated downward to cut the pipe, thereby completing the cutting process. The optimal rebound force not only ensures the cutting stability, but also reduces the operator's fatigue.
