[0002] The existing method for detecting the warpage of ring forgings is to place the forging ring flat on the detection platform, and obtain the warpage value of the segment ring through the gap value between the measured forging ring and the platform, so as to judge whether it is within the tolerance range and whether it is qualified or not. The HD180-1 ring forging is an important component provided by the special material company to a certain type of rocket of the China Academy of Launch Vehicle Technology. Due to the large size of the HD180-1 ring forging (outer diameter 4710mm, thickness 62-383mm, height 90~372mm), it exceeds the detection range of the existing method for detecting the warpage of ring forgings. The existing measurement method can no longer meet the measurement requirements.
