Problems solved by technology
At present, after the composite material preform is woven, there are still array steel needles formed in a certain regular shape array in the Z direction, and the array steel needles need to be replaced by Z-direction fibers, but the process of introducing Z-direction fibers is still manual.
This Z-direction fiber introduction method has high labor intensity, low production efficiency, and high labor cost. Moreover, due to the contact between the human hand and the fiber and the friction between the fiber and the traditional yarn replacement needle, the quality of the fiber is reduced, which affects the quality of the yarn. The overall quality of the preform
Therefore, manual introduction of Z-direction fibers into three-dimensional fabrics can no longer meet the needs of the market, and there is an urgent need for an automatic Z-direction fiber implantation device for composite material prefabricated bodies to complete automated production

The invention designed a composite material prefabricated body Z to fibrous automation implant device, which belongs to the field of advanced manufacturing technology.At the same time, the combined action of the array steel needle clamping mechanism completes the process of replacement of the meta -steel needle. The three -dimensional fabric is designed to lift the yarn rack on the side of the three -dimensional fabric.Complete the introduction of the three -dimensional fabric Z towards fiber, and form a wire ring after the introduction of Z to the fiber. The diameter of the wire ring is increased through the ring shaped mechanism.After passing the row of wire rings, remove the metal rod along the thread ring, and leave the yarn in the wire ring, so as to complete the suture of the three -dimensional fabric. The invention has proposed a composite material prefabricated body Z to fibrous automation device.Improve the accuracy and work efficiency of Z to the fiber introduction process.
Description
technical field [0001] The invention designs an automatic Z-direction fiber implantation device of a composite material preform, which belongs to the technical field of advanced manufacturing. Background technique [0002] Composite components are widely used in aerospace, military and other fields, so the requirements for the structure and performance of composite materials are also increasing. Compared with two-dimensional composite components, 3D structural composite components have introduced reinforcing fibers in the Z direction. The interlaminar strength in the thickness direction of the carbon fiber three-dimensional fabric is solved, and the problems of easy delamination of composite components, low impact toughness and damage tolerance are solved. At present, after the composite material preform is woven, there are still array steel needles formed in a certain regular shape array in the Z direction, and the array steel needles need to be replaced by Z-direction fibe...
