AI Technical Summary

Technical Problem

In the production of three-dimensional fabrics in the aerospace field, the existing mechanized needle punching process is complex, has low production efficiency, and is difficult to meet the needs of rapid development. Moreover, the existing equipment lacks stability and precision.

Method used

A rapid fabrication platform using a combination of irregularly shaped preforms and various structural components is employed, including a needle-punching robot, a mold device, a winding device, and a circular track. The needle-punching and winding functions are independently driven by a dual-drive turntable device for the mold. The needle-punching robot and winding device are combined to perform multiple parallel operations. The assembled support core mold and limiting device are used to improve stability and accuracy.

Benefits of technology

It enables efficient and stable parallel operation of multiple processes, improves production efficiency, enhances the stability and precision of the equipment, and meets the mechanized production needs of large-size fabrics.
