  • Metal spinning is a processing technology of metal plastic forming.
  • Spinning process is a complex elastic deformation process. The nonlinear boundary contact conditions make the spinning mechanism more complex.
  • Due to the complexity of spinning mechanism, the stress and strain distribution of each point of the spinning workpiece are very uneven; Due to the influence of many process parameters, the spinning process is also complicated.

Ordinary spinning
It is mainly to change the blank shape, while the wall thickness size is basically unchanged or changed less. This kind of spinning forming process is called ordinary spinning. Ordinary spinning is mainly used to change the diameter of sheet metal to form workpieces. It is a non cutting forming process for processing thin-walled revolving bodies. It is used to feed rotating metal circular plates or preformed blanks through rotary wheels and then spin them to form
Thinning spinning
The spinning forming process in which the blank shape and wall thickness change at the same time is called thinning spinning, also called powerful spinning. The difference between thinning spinning and ordinary spinning is that thinning spinning belongs to volume forming. In the deformation process, the wall thickness is mainly reduced while the blank volume remains unchanged. The shape of the finished product is completely determined by the size of the mandrel, and the accuracy of the finished product size depends on the reasonable matching of process parameters

As a new process product, spinning pulley has been widely used in automobile engines, such as motor wheel, water pump wheel, air conditioner wheel and fan wheel. According to the groove type and processing technology of belt pulley, it can be divided into three categories: split pulley, folding pulley and multi wedge pulley. The schematic diagram is as follows:

The thickness of materials selected for the multi wedge wheel is 2~6mm, generally 3mm. The blank is made by drawing and stamping, and is processed on a spinning machine. The tooth profile is formed by metal flow and plastic deformation on the material wall thickness by extrusion.

The thickness of the material selected for the folding wheel is 1.5~2.5mm, which is also made by drawing and stamping, and processed on the spinning machine. Since no metal flow occurs in the forming process of the folding wheel, the process is relatively simple and there are few factors affecting the quality

The material thickness of the splitting wheel is 2~4mm. Generally, one time blanking is used to make the blank, and the spinning wheel is used to split from half of the material thickness on the spinning machine and then reshape to form. Because of its simple processing technology and few factors affecting the quality, the most important is the flatness of the blank itself. Therefore, the punching die for offset cutting has higher requirements.
