Abstract

Abstract: To achieve single-sided stitching on composite material preforms, improve production efficiency, and ensure consistent product quality, a single-sided double-needle double-thread sewing head is designed based on the single-sided double-needle double-thread stitching process. Firstly, it can achieve variable-angle stitching on one side of the composite material preform, increasing the thickness of the stitched preform and enhancing its shear stress resistance. Secondly, the sewing head adopts a dual-motor drive and incorporates related structural designs such as the swinging stabbing mechanism and synchronous transmission mechanism. The overall design and assembly of the sewing head are carried out in Pro/E, and the strength verification of the suture needle is performed using Workbench software. Finally, assemble the single-sided double-needle double-thread sewing head.

Key words: single-sided double-needle double-thread stitching process, single-sided double-needle double-thread sewing head, swinging stabbing mechanism, strength check, composites
