In 1985, the 59th Institute of ordnance industry successfully used the cold rotary forging process to realize the cold forming of end tooth profile for the first time in China. As shown in the figure, the developed parts are end gears for motorcycle starting mechanism. The material is 15CrMo...
At present, Britain, Japan, China, the former Soviet Union and Poland have done a lot of work on the research of swing rolling, mainly focusing on the calculation and verification of force and energy parameters and the measurement of surface pressure distribution in the contact area; The main methods...
At present, the countries producing rotary forging machines in the world include Japan, Germany, Switzerland, Poland and so on. In recent years, manufacturers in these countries have newly designed swing rolling machines of different specifications on the basis of the production of the original models, so that the swing...
Rotary forging is a new type of pressure processing technology, which has only entered the practical stage in the s. In recent years, it has been widely used in China. The appearance and internal quality of finished parts can be greatly improved by machining precision tooth profile with cold...
Rotary forging has the following characteristics: Labor saving. Firstly, the deformation force during forging is determined by the product of average unit pressure and contact area, while rotary forging is a continuous local deformation process, and the contact area is only half of that of conventional forging; At the...
