Description
Technical Field
The invention relates to a three-dimensional special-shaped integral automatic weaving device, and belongs to the technical field of weaving equipment.
Background
The three-dimensional special-shaped integral weaving technology is a novel weaving technology at present, and high-performance fibers are distributed in space and are interwoven with each other to form a prefabricated part with a reticular structure by changing the array shape and the motion form of a yarn carrier in a weaving chassis by using the technical characteristics of weaving technology and equipment. The three-dimensional fabric woven by the technology has the advantages that fibers are distributed in a multi-direction mode in the space and are mutually interwoven to form a non-layered integral net-shaped structure, and various irregular prefabricated parts can be woven and formed in an integral near-net-size mode, so that the material characteristics are prevented from being damaged due to the subsequent machining of composite material sections or components, and the stability and the reliability of the mechanical properties of the components are effectively guaranteed. The weaving process method realizes a multi-layer high-thickness structure which cannot be solved by a weaving process, so that the weaving structure has better integrity, stronger shearing performance and structural designability. The method not only can effectively avoid the defect of poor performance between two-dimensional braided layers, but also can reduce the cost, shorten the production period, and easily prepare complex structural parts and the like.
In the weft-warp knitting, a yarn carrier on a machine base moves in a predetermined path on a longitudinal and transverse track in a cycle of a predetermined number of steps, and the carried yarns are continuously interlaced in a space to finally form a preform of a predetermined shape. At present, the longitudinal and transverse type knitting machine is simple in structure, convenient to arrange and combine, and easy to weave preformed bodies in different shapes, and the formed preformed bodies and composite materials thereof have the characteristics of strong adaptability, stable structure, excellent mechanical property, good integrity, high damage tolerance and the like, so that the longitudinal and transverse type knitting machine is more widely applied to the fields of aerospace, national defense and military industry.
At present, the four-step method knitting is a popular knitting method at present. Currently, most of the vertical and horizontal weaving machines are 50 rows × 50 rows or 40 rows × 40 rows of module units, and when large-size complex configurations such as L-type, T-type, pi-type, and revolving bodies are woven, the module weaving machines need to be combined. Therefore, when weaving these components, the edge yarn carriers need to be manually adjusted, and the basic four-step method will be expanded to 4N times, which all increases the difficulty of the weaving process. Generally, once the operation fails, the operation cannot be recovered, and fatal holes are formed on the structural components, so that the reliability and the bearing efficiency of the components are greatly reduced during the service process.
