Multi-pass heating spinning forming method for high-strength titanium alloy plate

The invention belongs to the technical field of metal plate plastic forming, and particularly relates to a high-strength titanium alloy plate multi-pass heating spinning forming method which has the beneficial effects that the problems that conventional flame heating is not uniform, the production efficiency is low and the forming difficulty is large can be solved, the product quality and the machining stability can be improved, and the production cost is reduced. The heating temperature is set through the system, the temperature is detected through a sensor and fed back to the system for comparison, the system adjusts the nozzle gas flow according to the feedback result to control the spinning temperature, the heating position can adapt to continuous changes of the material deformation position, it is guaranteed that the temperature of a forming area is constant, and the intelligent constant-temperature hot spinning machining method is achieved. And the temperature of the spinning material can be recorded in
