Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing parts processing, in particular to a cutting-friction stir welding combined processing equipment and a cutting-friction stir welding combined processing and manufacturing method. Background technique [0002] At present, for the manufacture of structural parts with internal closed cavities, the traditional manufacturing methods mainly include the use of profile welding, plate welding and bulging processing, or the entire workpiece is cut and then sealed with a cover plate. These traditional processing methods have many steps, long manufacturing cycle, high manufacturing cost, and the workpiece is easily deformed, which affects the strength of the structural part. [0003] In 1991, W.M.Thomas of the British Welding Institute (TWI) invented the friction stir welding technology. This new welding technology derived from the mechanical cold processing manufacturing process and based on...

Problems solved by technology

[0005] However, for components with an internal closed cavity structure, such as cooling plates, in addition to the split processing method, traditional friction stir welding still lacks effective processing methods. Therefore, can the whole material be used, by welding Technology and cutting technology are integrated, and it is of great significance to carry out joint processing and manufacturing to form parts with an internal closed cavity structure at one time. For traditional mechanical manufacturing methods, this processing technology is also an important tool for mechanical manufacturing. Milestone innovation in the field, promote the development and progress of machinery manufacturing technology, form innovative machinery manufacturing technology with low cost, less process, and short cycle, provide strong support for the sustainable development of the world economy, and firmly believe that this The emergence of new technologies for combined processing and new theories of mechanical manufacturing will surely become one of the most important and widely used welding and manufacturing technologies in the world in the 21st century
