Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, specifically to a pipe cutting device. Background Technology

[0002] Pipe cutting devices are widely used in construction, industrial manufacturing, municipal engineering, and home decoration, primarily for cutting pipes of various materials such as metal, plastic, and composites to a fixed length. Traditional cutting methods rely on manual sawing or simple mechanical cutting equipment, resulting in low efficiency, rough cuts, and large dimensional deviations. Especially for high-hardness metal pipes or large-diameter pipes, manual operation can easily lead to accelerated blade wear, uneven cut surfaces, and even safety hazards. While existing semi-automatic or fully automatic cutting equipment improves cutting accuracy through hydraulic and servo systems, it generally suffers from complex structures, high energy consumption, and insufficient adaptability to different materials or pipe diameters. For example, when cutting plastic pipes, frictional heat can easily cause the material to melt and deform, while metal pipe cutting requires frequent blade replacements to cope with high-load conditions. Furthermore, traditional devices often lack intelligent detection and adaptive adjustment functions, making it difficult to meet the needs of high-precision assembly or complex engineering scenarios. Therefore, there is an urgent need to develop an efficient, multi-purpose intelligent pipe cutting device that can accommodate the characteristics of different materials.

[0003] Utility model patent with application number CN202421641198.7 and publication number CN222448478U (hereinafter referred to as "Prior Art 1") discloses a pipe cutting machine for water and electricity installation, including a cutting mechanism and a quick clamping mechanism. The quick clamping mechanism is fixedly connected to the front of the cutting mechanism. The quick clamping mechanism includes a clamping box. A motor assembly is fixedly connected to the back of the inner cavity of the clamping box. A disc assembly is fixedly connected to the output end of the motor assembly. A pivot pin assembly is fixedly connected to the top of the front of the disc assembly. A horizontal frame assembly is sleeved on the surface of the pivot pin assembly. Both sides of the horizontal frame assembly are slidably connected to the inner wall of the clamping box. Wheel rods are fixedly connected to both sides of the top of the horizontal frame assembly. A trapezoidal block is slidably connected to the top of the wheel rod.

[0004] The specification of prior art 1 discloses a pipe cutting machine for cutting insulating sleeves. When in use, it changes the traditional method of fastening by fastening bolts and uses a clamping frame to clamp the workpiece body, which does not require a lot of force. However, in practical applications, since the size of the table is fixed, it is not possible to cut long pipes in a fixed manner, and the applicable range is small. Summary of the Invention
