A three-dimensional braiding machine discretization mandrel system based on variable-curvature special-shaped rotators

Abstract

The invention discloses a three-dimensional braiding machine discretized core mold system based on a variable-curvature special-shaped rotary body, comprising: a core mold assembly unit, a core mold lifting unit, and a PLC, and the core mold assembly unit is connected with the core mold lifting unit. , the PLC is respectively connected with the core mold assembly unit and the core mold lifting unit; the core mold assembly unit includes: a discrete core mold layer unit, a core mold interlayer locking mechanism, and a core mold layer unit lifting mechanism. The discretized core model layer unit is composed of variable curvature core model layer slices, the discrete core model layer unit is arranged on the core model layer unit raising mechanism, the core model layer unit rising mechanism and the core model layer interlayer locking mechanism Both are fixedly connected with the core mold lifting unit. The discrete mandrel system of the three-dimensional braiding machine of the invention avoids the interference between the mandrel and the yarn, and ensures the three-dimensional weaving of the variable-curvature special-shaped revolving body with constant weaving fell height.

Description

technical field [0001] The invention relates to the technical field of three-dimensional knitting machines, in particular to a three-dimensional knitting machine discretization core mold system based on a variable-curvature special-shaped rotating body. Background technique [0002] The three-dimensional weaving technology is developed based on the two-dimensional weaving technology and can be used to manufacture three-dimensional fabrics. The fabric has the characteristics of multi-directional fiber orientation and overall continuous distribution, and has a series of excellent mechanical and thermal properties. At present, three-dimensional braided composite materials have been widely used in aviation, aerospace, automobiles, communication and other fields, such as: aircraft propeller blades, rocket throat linings, wind turbine blades, carbon fiber frames and automotive parts. [0003] The three-dimensional weaving technology has the ability of profiling processing. The pro...

Problems solved by technology

For large-scale variable-curvature special-shaped gyratory, the shape of the mandrel will be more complicated, such as a cone with a small top and a large bottom. When the yarn is woven on the upper mandrel, it may interfere with the lower mandrel. collide with
