Description

Technical Field

[0001] The utility model relates to the technical field of composite pipes, in particular to a positioning mechanism for cutting composite pipes. Background Art

[0002] Composite pipes have a wide range of applications, mainly including: 1. Industrial field: Composite pipes are widely used in chemical, electric power, metallurgy, petroleum and other industries, effectively solving the problem of conveying corrosive, high temperature, high pressure and other special media; 2. Construction field: Composite pipes are often used in pipes of building water supply and drainage, heating and other systems, meeting the diversified needs of pipe materials, while reducing the number of pipe joints and improving the reliability of the system; 3. Municipal field: Composite pipes are suitable for municipal projects such as urban water supply, water supply and drainage, gas, and central heating, which can ensure the long-term operation and safety of pipelines; in routine use, composite pipes need to be cut into pipes of different lengths. The invention relates to a cutting device for cutting pipes of different lengths. The cutting device is designed to meet the needs of different scenarios. However, when the existing cutting device is used, the composite pipe is usually fixed (pressed) on the workbench, and then the composite pipe is cut by a cutting knife. When cutting, the cutting knife continues to move downward to cut the pipe. However, when the same cutting device is used to cut pipes of different lengths, different equipment is required to fix pipes of different lengths. On the one hand, the manufacturing cost is high, and the corresponding equipment needs to be replaced according to the length of the pipe. On the other hand, the cut pipes are of different lengths. If the same equipment is used to fix them, the pipes with excess length that are not fixed are prone to jumping during cutting. Utility Model Content
