Embodiment 1

[0040] As shown in the figure, the multi-point pressing device for controlling the density and uniformity of the complex curved surface stitched fabric layer includes a male mold, a female mold, a multi-point pressing tooling assembly and two supports;

[0041]The female mold is set on the periphery of the male mold, and the shapes of the female mold and the male mold match each other; the fabric to be pressed, the female mold and the male mold are all semi-conical structures with gradually increasing axial dimensions (such as Figure 1-4 shown); the male die is located between the two supports, and the two ends of the female die are respectively detachably connected to the two supports.

[0042] The multi-point pressurization assembly includes: an arched bracket and a pressurization assembly; the arched bracket is erected on the periphery of the female mold; the pressurization assembly includes a screw, a rotating handle and a rubber pad, the screw is threaded on the arched br...

Embodiment 2

[0052] It is basically the same as Embodiment 1, the difference is that the arch support is a hollow frame structure, the screw rod is screwed on the arch support through the pins with threaded holes filled in the arch support, and the pins with thread holes are at least One end is fixed on the arch bracket through the retaining ring and the cotter pin passing through the retaining ring and the threaded hole pin;

[0053] The multi-point pressurizing device for controlling the density and uniformity of the stitched fabric layers on complex curved surfaces also includes a fixing plate on which the two supports and the arch bracket are installed.

Abstract

The invention discloses a multi-point pressurizing device for controlling layer density and uniformity of a complex surface stitched fabric. The device comprises a male mold, a female mold and a multi-point pressurizing component, wherein the multi-point pressurizing component comprises an arched bracket and a pressurizing component; the arched bracket is arranged at the outer periphery of the female mold; the pressurizing component comprises a screw rod, a rotating handle and a rubber pad; the screw rod is in threaded connection to the arched bracket; one end of the screw rod penetrates through the arched bracket to extend to the outer surface of the female mold, and the other end is left outside the arched bracket; the rotating handle is connected to one end, left outside the arched bracket, of the screw rod; and the rubber pad is arranged at the end part of one end, extending to the outer surface of the female mold, of the screw rod. The multi-point pressurizing device for controlling the layer density and the uniformity of the complex surface stitched fabric is simple in structure, is easy to be machined and assembled, is convenient for use, and can effectively control the layer density and the uniformity of the complex surface three-dimensional fabric to improve the quality of the complex surface stitched fabric.

Description

technical field [0001] The invention relates to a multi-point pressurizing device for controlling the density and uniformity of a complex curved surface stitched fabric layer, which belongs to the field of fabrics. Background technique [0002] Seamed composite materials have the characteristics of strong anti-delamination ability, excellent anti-fatigue performance, good overall performance of components, light weight, high strength, and ablation resistance. At present, suture composite materials have been widely used in cutting-edge fields such as aviation, aerospace, and military industry, and have been extended to automobiles, construction, energy, environmental protection, biomedicine, and sports equipment. [0003] With the wide application of three-dimensional fabrics of suture composite materials, the shape and size of three-dimensional fabrics tend to be large-scaled and shaped, and the thickness is thicker. Vacuuming and pressurizing, pre-tensioning materials, etc...
