Measuring method and measuring device for skin stretch forming
By placing laser rangefinders under the skin stretching mold and performing position calibration and reading fitting, the problem of difficulty in assessing the skin stretching state is solved, enabling efficient assessment of skin stretching accuracy and real-time feedback of the production process, thereby improving the digitalization and intelligence level of skin production.

AI Technical Summary
In the existing technology, the skin stretching state is difficult to assess, and the stretching accuracy assessment is insufficient, which affects the quality of skin stretching production.
Multiple laser rangefinders are placed on a preset cross-section below the forming mold. The positions of the laser rangefinders are calibrated and mapped onto the forming digital model of the skin. The actual readings are recorded and the actual cross-sectional line is fitted. The mold gap and springback are calculated. Online measurement is performed in conjunction with a 3D scanner and a detection module.
It reduces the difficulty of assessing the skin stretching state, fully evaluates the skin stretching accuracy, realizes real-time feedback and quality assessment of the skin stretching state, and improves the digitalization and intelligence level of the production process.
