Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing equipment, in particular to a planetary pipe cutting machine. Background Art

[0002] Metal pipes are needed in many industries, especially in the fields of clean pipe cutting and beveling in beer, pharmaceuticals, biotechnology, beverages, dairy products, water treatment, etc. The metal pipe cutting and processing devices on the market are similar to lathe processing centers, which belong to machine tools and can only be used in factories. Professionals are required, and coolant is needed during the cutting process, causing pollution. The cut workpiece needs to be cleaned after processing, which increases personnel costs and corporate costs. However, it is inconvenient and unsuitable for use in pipeline construction. Therefore, the planetary pipe cutting machine was invented.

[0003] The structure of the hand-cranked planetary pipe cutting machine in the prior art is shown in the attached figure Figure 1 As shown, it is suitable for cutting metal pipe materials. It is a convenient and practical pipe cutting device. It is easy to operate, easy to carry, and saves space. At the same time, it can meet the requirements of the bevel. The rear end face after cutting is absolutely vertical, and the end face is burr-free. It can provide a fundamental guarantee for high-quality pipe welding. The stainless steel brush plays a vital role as a key component; every time the saw blade completes a cut, the stainless steel brush rotates quickly, gently and firmly cleaning the residue and debris on the saw blade. This not only ensures the sharpness of the saw blade, but also extends its service life. Since the saw blade needs to be replaced after cutting pipe fittings of different materials and sizes or cutting a certain number of times, the saw blade needs to be replaced frequently, and the saw blade partially extends into the stainless steel brush. Therefore, it is also necessary to correspond to the stainless steel brush that is frequently installed and disassembled to cooperate with the saw blade. The stainless steel brush in the planetary pipe cutting machine in the prior art is usually fastened and installed by bolt connection. The installation and disassembly of the stainless steel brush is relatively cumbersome and inconvenient, which affects the replacement efficiency of the saw blade and the overall convenience of use.

[0004] Therefore, it is necessary to provide a planetary pipe cutting machine to solve the above technical problems. Utility Model Content
