Abstract：

In order to further research the neck-spinning mechanism of the high-pressure tank plate, its neck-spinning process was simulated by the FEM software Deform-3D.The simulation results show that the deformed metal in the contact zone between the tube and the plate is in a 3D compressive stress state, and the plastic state is very good. In the whole forming process, the changes of the equivalent stress and equivalent strain rate are both basically consistent with the trends that first increase and then decrease. The equivalent strain substantially distributes along the axial stratification, and the equivalent strain on the same layer circumferential direction is essentially equal. Among the three components of spinning force, the radial component is the largest, and the tangential component is slightly larger than the axial component. Cylinder thickening effect is very obvious, and the biggest thickness value appears on the bottleneck transition, where wrinkles are prone to occurring. The neck-spinning test of the tank was operated by self-designed 610 hot spinning machine. The test results coincide with the simulation results.
