The manufacturing process of automobile panel dies is relatively complex. Good stamping manufacturability can not only simplify the stamping process, but also greatly reduce the capital investment in stamping die manufacturing.

Practical problems

       1

1. Automotive panel parts are large‑sized (3 m in length and 2 m in width), feature complex shapes, and are difficult to move. Traditional measuring tools (such as checking fixtures, 2D measuring machines, and CMMs) cannot perform the inspection work at all.

2. The client requires measurement of the mating areas between the upper and lower dies for automotive panel parts so as to optimize the precision of automotive panel dies and improve the enterprise's production efficiency.

Co3d solution

       Due to the large size and complex shape of automobile panel dies, positioning is difficult and movement is inconvenient. Therefore, compound dies are widely adopted for automobile panels. Automobile panel dies require extremely high precision. After two automobile panels are lapped together, their mating surfaces are supposed to form a single plane. If the fitting gap between them is excessively large, the quality of finished products will fail to meet standards. To address the problems faced by this enterprise, engineers from Hualang Technology proposed a solution: use the Hualang 3D Photogrammetry System (HL‑3DP) to take global photos of the automobile panel die, obtain the 3D coordinates of the marker points on the inspection area, import the captured photos into the software for calculation, then perform inspection, comparison and analysis between the calculated data and the original digital model drawing, so as to acquire the fitting error values between the automobile panel dies.
