Abstract:

In order to improve the automation degree of three-dimensional special-shaped overall braiding to thereby improve the braiding efficiency, by analyzing existing general methods and mixed style braiding method for three-dimensional special-shaped preforms and a chassis device capable of realizing specialshaped braiding, a driving device using a stepper motor as the fixed guide rail was proposed. By combining with the positioning function of direct urrent lectromagnet at both ends of the guide rail, the control of DMC5400A four axis trajectory card, IOC1280 IO expansion card and STM32F103 microcontroller was adopted to realize the chassis device capable of automatically braiding various pecialshaped
preforms. The structural composition and working process of special-shaped braiding of the chassis device were analyzed. The results show that the braiding process using the chassis device in combination with the control system can realize the flexible manufacturing of special-shaped preforms, and has broad application prospects.

Key words: three-dimentional special-shaped braiding, braiding process, flexible manufacturing, chassis device
