[0002] Thread rolling is a processing method in which two washboards move relative to each other so that the blank between them is rolled into a spiral groove. The thread rolling process is mostly used in bolt processing and production, replacing the original turning process, saving materials and reducing costs. Thread rolling machines are suitable for almost all machinery manufacturing industries, including machine tools, mold machinery, plastic machinery, printing machinery, packaging machinery, engineering machinery, automobile and motorcycle parts, aircraft engines, locomotives, tobacco machinery and general machinery, etc. The application range is extremely wide. If the existing thread rolling technology for bolt production does not take into account the cooling of the washboard teeth, the long-term operating temperature is too high, which will lead to plastic deformation of the teeth, resulting in problems such as inaccurate spiral groove size. At the same time, it is difficult to perform thread rolling on bolt blanks of different diameters. For this reason, we propose a thread rolling device for bolt production. Utility Model Content
