Problems solved by technology

[0003] At present, there are mainly two manufacturing methods for the composite cap 400 with stoppers. One is to lay up and solidify the U-shaped skin 410 first, and then lay up stoppers 430 on the surface after forming, but the skin is glued When the number of stoppers is large, the time cost of this method is too high; secondly, the U-shaped skin 410 and the stoppers 430 are laid up at the same time and formed by co-curing. Bonding quality
In short, both of the above two methods have the problems of many times of curing, low production efficiency and high production cost.

Embodiment 1

[0044] Such as Figure 1-7As shown, this embodiment provides a device for preparing a composite hat with a stopper, including a lay-up tool 100, a bonding tool 200 and a pressing tool 300. The lay-up tool 100 is used to form multiple U-shaped masks at one time. Leather 410; the bonding tool 200 includes a frame 210, which can be spliced ​​by a plurality of section steels and has high bearing strength. A rotatable multi-faceted cylindrical drum 220 is arranged on the top of the frame 210, and there are multi-faceted cylindrical drums 220. A strip-shaped positioning groove, a plurality of positioning grooves are distributed in a circular array around the axis of the multi-faceted cylindrical drum 220, and a positioning mechanism 230 is arranged in the positioning groove, and the positioning mechanism 230 is used for positioning and installing the stopper 430; The tooling device 300 includes a pressing plate 310 on which a plurality of bolt pressing mechanisms 320 are arranged. T...

Embodiment 2

[0057] Such as Figure 1-7 As shown, the present embodiment provides a method of operating a device for preparing a composite cap with a stopper, comprising the following steps:

[0058] Step S1: forming a plurality of U-shaped skins 410 on the lay-up tool 100;

[0059] Step S2: forming a laminate, using a cutting device to cut the laminate into a plurality of stoppers 430 according to the size requirements, and cleaning the stoppers 430 with a solvent after cutting and drying;

[0060] Step S3: Prepare a sufficient amount of room temperature curing adhesive in proportion;

[0061] Step S4: install the block 430 prepared in step S2 on the base plate 231 of the drum, apply the adhesive prepared in step S3 on the block 430 to form an adhesive layer 420, and then place the U-shaped skin 410 Paste the adhesive layer 420, then align the pressing plate 310 with the positioning column 233 and cover the U-shaped skin 410, and screw the bolt compression mechanism 320 in turn to conne...

Abstract

The invention discloses a composite material cap-shaped part preparation device with stop blocks and an operation method of the composite material cap-shaped part preparation device and relates to the technical field of composite material manufacturing processes. The composite material cap-shaped part preparation device comprises a laying tool, a gluing tool and a press-fit tool, and the laying tool is used for forming a plurality of U-shaped skins at a time. The gluing tool comprises a frame, a rotatable multi-face cylindrical rotating cylinder is arranged at the top of the frame, a plurality of long-strip-shaped positioning grooves are formed in the multi-face cylindrical rotating cylinder and distributed around the axis of the multi-face cylindrical rotating cylinder in an annular array mode, and positioning mechanisms are arranged in the positioning grooves and used for positioning and installing the stop blocks. The press-fit tool comprises a press-fit plate, a plurality of bolt pressing mechanisms are arranged on the press-fit plate, the press-fit plate can press the U-shaped skins on the stop blocks through the bolt pressing mechanisms, during operation, composite material cap-shaped parts can be formed on a roller in batches, and the composite cap-shaped part preparation device has the advantages that the curing frequency is greatly reduced, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of composite material manufacturing technology, in particular to a device for preparing a composite hat with a stopper and an operating method thereof. Background technique [0002] Composite materials are widely used in the aviation field because of their high specific strength, specific stiffness, and high degree of structural integration, as well as the ability to effectively reduce the number of parts and assembly time. In the composite material structure, the cap-shaped structure composed of U-shaped skin and stopper is more common, such as Figure 7 As shown, the composite hat 400 includes a U-shaped skin 410, an adhesive layer 420 and a stopper 430, which can effectively improve the torsional stability of the panel and reduce assembly costs, and are widely used in aircraft spoilers, etc. Airfoil structure. [0003] At present, there are mainly two manufacturing methods for the composite cap 400 with ...
