This invention relates to the field of sealing component punching technology, specifically a 3D sealing component punching device, including a punching frame and a movable sealing cover. The punching frame is internally equipped with a punching support unit and a punching adjustment unit. This invention uses a limit servo cylinder to push the movable limit frame downwards, causing the upper and lower support frames to form an upper and lower clamping support. At this time, a high-pressure air pump inside the metal frame inflates the rubber airbag. The airbag expands and compresses the internal granular filling layer. Utilizing the phase change effect generated by the dramatic increase in inter-particle friction, the originally loose and flowing granular layer instantly solidifies into a high-rigidity solid.
