Abstract

The invention relates to a design method of a two-dimensional braiding machine capable of braiding a special-section perform. Flat belt braiding spindle tracks are adopted; two flat belt braiding spindle tracks are spliced into an L, T or cross shape; by adjusting the number of total notches of all impellers on the flat belt braiding spindle tracks, the interference of spindles from different flat belt braiding spindle tracks at a track intersection is avoided; by adjusting the number of notches of individual impellers of the flat belt braiding spindle tracks, the interference of the spindles on the flat belt braiding spindle tracks after splicing at an intersection of every two adjacent impellers is avoided. According to the design method disclosed by the invention, one-time forming of a complex section braiding structure can be realized; in addition, complex mechanical structures such as a shifting fork and a track-changing turntable are not needed, no complex control system is needed, and high stability is realized.

Description

technical field [0001] The invention relates to the technical field of braiding machines, in particular to a two-dimensional braiding machine design method capable of braiding special-shaped section preforms. Background technique [0002] Two-dimensional weaving is a process in which three or more fiber bundles (yarns) are interwoven obliquely along the fabric forming direction according to specific rules. Traditional two-dimensional weaving is mainly used to produce ropes, shoelaces, cable shielding layers, etc. With the maturity of two-dimensional weaving technology, the application of weaving technology in the field of jewelry is also increasing. Two-dimensional woven fabric structures mainly include traditional tubular structures, flat belt structures, and modern flat belt structures, belt-tube combined structures, square structures, etc. In the field of composite materials, the 2D weaving process has become one of the most efficient production methods for preparing com...
