Profiling tool for divergent panel and using method of profiling tool

The invention discloses a profiling tool for a divergent panel and a using method of the profiling tool, and particularly relates to a profiling tool for a divergent panel of a 300 MW-level heavy gas turbine hood assembly and a using method of the profiling tool. The profiling tool aims to solve the problems that the cost is increased and the deformation is large when the divergent panel is machined, the divergent panel can rebound after being profiled, an end face of a flange of the divergent panel is difficult to machine subsequently due to allowance feeding of the end face of the flange of the divergent panel, and the size precision of a single piece is not easy to guarantee. The profiling tool comprises a connecting frame, an upper die body, a plurality of die heads, a bottom plate and a lower die body, wherein the connecting frame is installed on the upper die body, the die heads are installed on the lower surface of the upper die body, the lower die body is installed on the bottom plate, and a positioni
