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 pressurization device for controlling the density and uniformity of fabric layers stitched on complex curved surfaces, which includes a male mold, a female mold and a multi-point pressurization tooling assembly; the multi-point pressurization assembly includes: an arched bracket and a pressurization Components; the arched bracket is erected on the periphery of the female mold; the pressurized assembly includes a screw, a rotating handle and a rubber pad, the screw is threaded on the arched bracket, and one end of the screw extends through the arched bracket to the outer surface of the female mold, and the other end stay outside the arched support; the rotary handle is connected to the end of the screw rod left outside the arched support; The multi-point pressurizing device for controlling the layer density and uniformity of complex curved surface stitched fabrics in the present invention is simple in structure, easy to process, easy to assemble, convenient to use, and can effectively control the layer density and uniformity of complex curved surface three-dimensional fabrics, thereby improving complex curved surface stitching The quality of the 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...
