The invention discloses a flexible loading placement device for forming a dish-shaped part through laser flexible loading and a working method thereof. The flexible loading placement device for forming the dish-shaped part through laser flexible loading comprises a pulse laser generating system, a dish-shaped part forming system, a pressure clamp system, a flexible mold placement switching system and a dish-shaped part control system. Pulse lasers and flexible films serve as loading loads, and the requirement for the coaxiality of the high-precision dish-shaped part is met through a high-precision dish-shaped part multi-process forming mold. The dish-shaped part multi-process forming mold is assembled in a dish-shaped part multi-process forming mold mounting groove so that the dish-shaped part multi-process forming mold can be taken out, forming waste can be effectively removed, the problem that the mold is blocked by the forming waste after multiple times of machining is solved, and the service life of the mold is prolonged. The flexible loading process is automatic through the flexible mold placement switching system and the pressure clamp system, and thus the dish-shaped part manufacturing efficiency is improved.
