A manufacturer of large springs (typically 3" in diameter and 28" long) required a system for setting the springs compression length while automatically validating the springs rate and set length.
Creative Automation designed and fabricated a system that receives springs placed by an operator on the systems flight conveyor. Once in position, a servo controlled hydraulic ram engages the spring and compresses it past its elastic limit to a programmed set position. While the ram withdraws, the spring force is continuously monitored resulting in a force/displacement recording. The resulting data was used to certify each spring and provide a statistical database.
