Description

Technical Field

[0001] The utility model relates to the technical field of closed-angle beam forming, in particular to a closed-angle beam forming tool. Background Art

[0002] Some parts of aircraft structures have closed angle structures. For example, some beam structures have the angle between the web and the flange of the inner surface less than 90°, thus forming a closed angle. At present, composite materials are widely used in the aerospace field due to their superior performance, and more and more high-precision composite parts are made by curing molding process.

[0003] Composite parts need to be demolded after curing. When demolding beam structures with closed angles, most of them are lifted or lifted. Lifting demolding can easily damage the surface of composite parts, while lifting demolding can easily cause uneven force and improper operation, resulting in bending or even damage of composite parts. Therefore, demolding closed-angle beams after molding is very difficult, which directly leads to increased manufacturing costs and low molding quality. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a closed-angle beam forming tool which has a simple structure and can be quickly demoulded.

[0005] To this end, the technical solution of the utility model is: a closed-angle beam forming tool, including a curing platform, on which is provided at least one group of forming components, the forming components including a positioning base plate and a male mold, the positioning base plate is fixed on the curing platform, and the male mold is installed on the positioning base plate; the male mold is composed of multiple sections of metal movable blocks, and the metal movable blocks are fixed to the positioning base plate by positioning pins and screws.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the length and width of the male mold are both composed of at least two sections of metal movable blocks.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: a positioning pin hole and a threaded hole are provided at the bottom of the metal movable block, and each metal movable block is fixed on the positioning base plate.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the positioning base plate is fixed on the curing platform by bolts, and hanging rings are provided at both ends of the positioning base plate.

[0009] On the basis of the above solution and as a preferred solution of the above solution: a plurality of molding components can be arranged side by side on the curing platform.

[0010] During the curing process, the metal movable block is fixed to the positioning base plate by means of positioning pins and screws, and assembled into a positive mold according to the splicing requirements. The positioning base plate is then hoisted onto the curing platform by means of lifting equipment, and then the positioning base plate is fixed to the curing platform by means of bolts and other fasteners. The composite material is then laid on the positive mold, and the curing process of the closed beam is realized by means of the negative mold.

[0011] When demoulding, the female mold is demoulded normally first, and then the positioning base plate is released from the curing platform. The positioning base plate is hoisted by hoisting equipment, and then the screws and positioning pins on the positioning base plate and the metal movable block are removed, so that the metal movable block can be removed from the closed angle beam and the demoulding work is completed quickly.

[0012] Compared with the prior art, the utility model has the following beneficial effects: a split positive mold is adopted, and the positive mold is spliced ​​by multiple metal movable blocks. The metal movable blocks can be taken out separately during demolding. The contact surface between a single metal movable block and the composite material part is small, and the demolding resistance is small. After a single metal movable block is demolded, the remaining metal movable blocks become loose, and the demolding work can be completed quickly without damaging the surface of the composite material part, thereby ensuring the molding quality of the closed-angle beam.
