A core mold support and seven-way yarn planting spindle rotation parking device and seven-way yarn planting method

Abstract

The present invention discloses a core mold support and a seven-way yarn planting spindle rotation and parking device and a seven-way yarn implantation method. The device comprises a core mold support device, a seven-way yarn planting spindle parking device, a circumferential rotation device and a support base. The circumferential rotation device drives the seven-way yarn planting spindle parking device to a specified position. When the seven-way yarn planting spindle enters under the core mold from the outside and reaches the horizontal load-bearing plate of the seven-way yarn planting spindle parking device, a micro-cylinder drives a gate plate to lift and fix the seven-way yarn planting spindle. Then the circumferential rotation device drives the seven-way yarn planting spindle parking device to rotate a certain angle, so that the seven-way yarn planting spindle leaves the seven-way yarn planting spindle parking device and passes through the yarn gap, thereby automatically completing the seven-way yarn implantation.

Description

Technical Field

[0001] The invention relates to the field of three-dimensional seven-directional braiding and forming of composite materials, and in particular to a core mold support and a seven-directional yarn planting spindle rotation and parking device. Background Art

[0002] Three-dimensional structural composite materials are not only widely used in military industries such as shipbuilding and aerospace, but also in civilian industries such as wind power, nuclear power, transportation, engineering machinery and medical treatment because they are superior to traditional steel materials in terms of corrosion resistance, fatigue resistance and designability. Three-dimensional structural composite materials solve the defects and shortcomings of two-dimensional composite laminates, and gradually replace traditional steel materials in the main load-bearing components of large equipment and mechanisms. The structure of three-dimensional seven-way braided composite materials is complex. On the basis of three-dimensional braids, axial yarns are added along the braiding direction, and two sets of mutually perpendicular transverse weft yarns and longitudinal weft yarns are added in the plane perpendicular to the braiding direction to form the fifth, sixth and seventh components respectively. The three-dimensional seven-way braided structure can not only improve the performance of three-dimensional four-way braids along the braiding direction, but also significantly improve its mechanical properties in the plane. However, the preparation process of three-dimensional structural composite materials is not mature enough at present, and its production efficiency is low. Due to the insufficient development of production equipment, the forming size of three-dimensional composite components is also small, which restricts the wide application of three-dimensional structural composite materials.

[0006] Furthermore, a plurality of guide wheels are provided at the bottom of the horizontal load-bearing plate, and the guide wheels are respectively clamped on the inner side and the outer side of the circular track.

[0007] Furthermore, the circular ring is used to install and fix the core mold.

[0008] Furthermore, a circumferential rotating device is installed on the supporting base, which can drive the yarn planting spindle to move circumferentially.

[0009] Furthermore, a seven-way yarn planting spindle parking device is installed on the circumferential rotating device, which can meet the parking requirements of the seven-way yarn planting spindle when it enters the bottom of the core mold from the outside.

[0010] Furthermore, the support base includes a horizontal load-bearing plate and an aluminum profile frame.

[0011] Furthermore, during the preform weaving process, the seven-way yarn planting spindle parking device reaches the designated position so that the seven-way yarn planting spindle smoothly enters the seven-way yarn carrying spindle parking device.

[0012] Furthermore, the seven-way yarn carrying spindle parking device can rotate a certain angle along with the circumferential motion platform under the drive of the motor, and the seven-way yarn planting spindle passes through another yarn gap to complete a seven-way yarn implantation.

[0013] Furthermore, the inner edge of the gate plate is hinged to the bottom of the left and right limit baffles through a hinge structure.

[0014] The present invention also provides a technical solution for a seven-way yarn implanting method using the above-mentioned core mold support and a seven-way yarn implanting spindle rotating docking device: when implanting the seven-way yarn of a preform, the length of the retractable support rod is adjusted according to the size requirements of the preform, and the preform core mold is fixed on the mounting ring at the top of the retractable support rod. The circumferential rotation device drives the seven-way yarn implanting spindle docking device to reach a designated position. When the seven-way yarn implanting spindle enters the bottom of the core mold from the outside and reaches the horizontal load-bearing plate of the seven-way yarn implanting spindle docking device, the micro-cylinder drives the gate plate to lift and fix the seven-way yarn implanting spindle. Then the circumferential rotation device drives the seven-way yarn implanting spindle docking device to rotate a certain angle so that the seven-way yarn implanting spindle leaves the seven-way yarn implanting spindle docking device and passes through the yarn gap to complete a seven-way yarn implantation.

[0015] Beneficial effects: Compared with the prior art, the present application has the following beneficial effects: because it can have a rotating and docking yarn planting spindle at its center, it can achieve continuous implantation of seven-way yarns, that is, the implanted fibers are in a continuous and non-broken form, and the mechanical properties of the formed preform are better.
