Description

Technical Field

[0001] The utility model relates to the technical field of thread processing, in particular to a thread processing device. Background Art

[0002] Cable protection tube refers to a tubular protective structure with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged. Its main function is to protect the cable from damage by the external environment, thereby ensuring the normal operation of the cable and extending its service life. The selection and use of cable protection tubes need to consider many factors, including cable specifications, use environment, installation requirements, and budget. Cable protection tubes are made of various materials, including metals (such as steel pipes, cast iron pipes) and non-metals (such as rigid polyvinyl chloride pipes, clay pipes, concrete pipes, asbestos cement pipes, etc.). Metal protection tubes usually have high mechanical strength and electromagnetic shielding performance, and are suitable for occasions that need to withstand large external forces or electromagnetic interference. The cable protection tube needs to be threaded before use to ensure the quality and stability of the connection between the protection tube and the joints or other components.

Through the above structure, screws of different calibers can be quickly clamped and processed.

[0004] After searching the above patent, it was found that the clamping of objects of different sizes was handled. However, the milling cutter of the device cools down the object during processing, which results in that when the milling cutter comes into contact with the unprocessed object for processing, as the object is threaded by the milling cutter, the temperature between the milling cutter and the object gradually increases due to friction, resulting in a reduction in the service life of the milling cutter. At the same time, the object will deform due to heat. Utility Model Content
