Metal spinning is a processing technology of metal plastic forming.
The spinning process is a complicated elastic deformation process. The nonlinear boundary contact condition makes the spinning mechanism more complicated.
Due to the complexity of the spinning mechanism, the stress and strain distribution at each point of the spinning workpiece are very uneven; Due to the influence of many process parameters, the spinning process is also very complex.
Ordinary spinning
It is mainly to change the blank shape, while the wall thickness is unchanged or slightly changed. This spinning-forming process is called ordinary spinning. Familiar spinning is mainly used to change the diameter of the metal plate to form the workpiece. This is a noncutting forming process for machining thin-walled revolving bodies. It is used to feed the rotating metal round plate or prefabricated part through the rotating wheel and then rotate to form.
Thinned spinning
The spinning forming process in which the blank shape and wall thickness change simultaneously is called light spinning, also called vigorous spinning. The difference between lean and ordinary spinning is that light spinning belongs to block forming. In the deformation process, the wall thickness mainly decreases while the blank volume remains unchanged. The spindle size ultimately determines the shape of the finished product, and the precision of the finished product size depends on the reasonable matching of the process parameters.
