Embodiment 1

[0048] This embodiment provides a simple method for sewing large-size and complex shaped prefabricated fiber cloth, using an auxiliary sewing device for sewing. The auxiliary sewing device is as follows: figure 1Said, including two relatively sliding first stainless steel plate 1 and second stainless steel plate 2, the thickness is 2.5mm, there are through holes 5 on the support plate, the hole spacing is 7mm, and the hole diameter is 2.5mm. The auxiliary suturing device also includes four threaded rods 3, a hole is respectively arranged on the four corners of the first stainless steel plate 1 and the second stainless steel plate 2, and the threaded rod 3 passes through the hole. The auxiliary suturing device also includes a nut 4, which is located at the connection between the first stainless steel plate 1 and the screw rod 4 and at the connection between the second stainless steel plate 2 and the screw rod 4, and is used for fixing the support plate.

Embodiment 2

[0059] This embodiment provides a simple method for sewing large-scale and complex shaped prefabricated fiber cloth. The auxiliary sewing device is used for sewing. The auxiliary sewing device includes two relatively sliding first stainless steel plates and second stainless steel plates with a thickness of 5 mm. , There are through holes on the support plate, the hole spacing is 4mm, and the hole diameter is 3mm. The auxiliary suturing device also includes two parallel slide rails, and the first stainless steel plate and the second stainless steel plate can slide relative to each other along the slide rails. The auxiliary suturing device also includes buckles, which are located at the connection between the support board and the slide rail, and are used to fix the support board.

[0060] The length of the fiber preform of the component in this embodiment is 0.8m, so the distance between the first stainless steel plate and the second stainless steel plate is fixed at 1.2m.

Abstract

The invention discloses a simple and convenient sewing forming method for large-size complex special-shaped preform fiber cloth, according to the method, an auxiliary sewing device is used for sewing, the auxiliary sewing device comprises two supporting plates which can slide relatively, and through holes which are regularly distributed are formed in the supporting plates. Extending the two end faces of the component model to be equal to the distance between the two supporting plates by utilizing three-dimensional drawing software; the method comprises the following steps: taking a plurality of sampling lines from parts (a curved surface generatrix and an edge line) with large curvature radius change according to an inner profile diagram of a special-shaped component model, and respectively printing plane distribution conditions of two end points of the sampling lines; the printed plane distribution conditions are attached to supporting plates respectively, and through holes, corresponding to the two end points of the sampling line, in the two supporting plates are obtained; the two end points of the sampling line are connected with the corresponding through holes in the two supporting plates through supporting lines. All the supporting lines form an approximate inner curved surface of the special-shaped prefabricated body, so that the shape of the fiber cloth can still be maintained when the fiber cloth of the profiling laying layer is transferred to the supporting lines.

Description

technical field [0001] The invention relates to the technical field of forming fiber cloth prefabricated parts, in particular to a method for simple sewing and forming of large-sized and complex special-shaped prefabricated fiber cloth. Background technique [0002] For large-scale complex special-shaped components, it is generally required to use profiling near-net size molding, and special-shaped molds (aluminum, steel, graphite, etc. Other methods are not suitable for introducing fibers in the thickness direction of the laminated fiber cloth with molds, and only hook seams can be used. The following problems exist in manual hook seaming: (1) It is difficult to accurately control the hook seam spacing, which affects the consistency of quality; (2) For smaller suture spacing (such as 3mm×3mm, 5mm×5mm), two or more times must be used Misplaced hook seam, the sewing efficiency is low; (3) The thickness of the prefabricated part suitable for one hook seam is about 3mm. For th...
