Description

Technical Field

[0001] This utility model belongs to the field of composite material manufacturing, specifically, it relates to a tooling platform suitable for molding composite material components in an autoclave. Background Technology

[0002] With the rapid development of composite materials, composite components are widely used in aerospace and other technological fields. Autoclave molding is one method for molding composite components, but the limited space available for molds on the single-layer transfer platform within the autoclave restricts the output of composite materials. Currently, various production units in the industry are actively promoting "double-layer" or "multi-layer" production solutions for composite materials. This involves stacking one or more tooling platforms on top of the existing single-layer transfer platform inside the autoclave to accommodate as many molds as possible, thereby increasing the output per autoclave and improving equipment utilization.

[0003] In the existing technology, there are certain shortcomings in the stacking process of tooling platforms: (1) the upper and lower layers need to be precisely matched when stacking tooling platforms; (2) the connection and fixing device between stacked tooling platforms has a complex structure. Utility Model Content

[0004] In view of the above-mentioned prior art, the purpose of this utility model is to overcome the shortcomings of the prior art, adapt to the actual needs, and thus provide a tooling platform that is easy to install and suitable for autoclave molding of composite material components.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tooling platform suitable for hot autoclave molding of composite material components, including a panel frame, a panel, support legs, U-shaped hooks, pads, lifting rings, and lifting ring mounting blocks. The panel frame is a grid-shaped frame structure, and the panel is a grid-type panel with multiple grid holes. The bottom of the panel is welded to the top of the panel frame. Multiple U-shaped hooks and two lifting ring mounting blocks are welded to the long sides of both sides of the panel frame, and a lifting ring is screwed onto each lifting ring mounting block. There are at least four support legs, and the tops of the four support legs are welded to the bottoms of the four top corners of the panel frame, and a pad is welded to the bottom of each support leg.

[0006] Furthermore, the panel is rectangular in shape, with the total length and width of the panel being greater than the total length and width of the panel frame, respectively, and the panel extending beyond the panel frame by no more than 50mm on all four sides. The grid holes on the panel are rectangular holes formed by welding together reinforcing ribs and steel bars.

[0007] Furthermore, the panel frame is made of rectangular steel.

[0008] Furthermore, the support leg is a cuboid made of square steel, and the height of the support leg is no more than 1000mm. Each support leg is also welded to the long side of the panel frame with a reinforcing rib to form a triangular structure. The number of support legs can be appropriately increased according to the size of this tooling platform. The top of each support leg is welded to the bottom plate of the panel frame, and the distance between each support leg is no more than 1500mm.

[0009] Furthermore, anti-slip blocks are provided, with at least four anti-slip blocks. Each anti-slip block includes a body and an L-shaped flange. The body is L-shaped, and the L-shaped flange is perpendicular to the body and extends outward from the L-shaped opening at one end of the body. The L-shaped flange has positioning holes. One end of each anti-slip block is fixed to the autoclave transfer platform by inserting a positioning pin into the positioning hole on the L-shaped flange. The other end of each anti-slip block contacts the outside of a pad and blocks the bottom of the support leg.

[0010] Furthermore, the spacing between multiple U-shaped hooks is no more than 200mm, and the U-shaped hooks are set with their openings facing upwards. The U-shaped hooks are welded to the two long sides of the panel frame through one end of their openings.

[0011] Furthermore, the lifting ring is a universal swivel lifting ring.

[0012] Furthermore, the tooling platform suitable for autoclave molding of composite material components has multiple layers, which are stacked vertically, and each tooling platform is connected to the others by a limiting block.

[0013] Furthermore, at least four limiting blocks are provided, all of which are L-shaped structures. Multiple U-shaped grooves are provided on one side of the L-shaped structure of the limiting block. One end of each limiting block is inserted into a rectangular hole on the panel of the lower tooling platform through the U-shaped groove on one side of the L-shaped structure, and the other end of each limiting block contacts the outside of a pad block on the upper tooling platform, thus connecting the two tooling platforms of the adjacent layers.

[0014] Furthermore, the width and spacing of the U-shaped groove on the limiting block are matched with the thickness and spacing of the steel strips and reinforcing ribs on the panel, respectively.

[0015] In this invention, the tooling platform is a frame structure, consisting of a panel, panel frame, support legs, and reinforcing ribs. The panel has a grid structure, and each support leg is equipped with a pad. The support legs and panel frame are welded together by reinforcing ribs to form a triangular structure. Lifting ring mounting blocks and hooks are provided on the sides of the panel frame. The lifting ring mounting blocks are used to install lifting rings, which are used for lifting and transferring the tooling platform. The hooks are used to bundle the vacuum hoses inside the autoclave. The tooling platform is placed on a single-layer transfer platform inside the autoclave. Anti-slip blocks are used for positioning between the tooling platform and the transfer platform, and positioning pins connect the anti-slip blocks to the transfer platform. When the tooling platforms are stacked, simple limiting blocks are used for positioning, and the position of the limiting blocks can be changed according to the stacking position of the tooling platforms.

[0016] The beneficial effects of this utility model are as follows: This tooling platform features a simple structure, good ventilation, and a large load-bearing capacity. Its anti-slip device effectively prevents the support legs from slipping under load, improving platform stability. The stacking and fixing device for the tooling platform is simple and easy to operate, effectively reducing relative displacement during transportation or use and lowering safety hazards. Furthermore, the placement of the upper platform is not restricted by a specific location when stacking, offering high adjustability. The hooks on the tooling platform effectively bundle the vacuum hoses inside the autoclave, preventing the hoses from scratching the auxiliary materials on the surface of parts.

The anti-slip block 6 is fixed to the autoclave transfer platform by inserting a positioning pin into the positioning hole 13 on the bottom L-shaped flange 12. The upper part of the anti-slip block 6 blocks the tooling platform support leg 3. Bottom; the limiting block 7 is an L-shaped multi-groove shape, with its grooves being U-shaped grooves 11. The groove width and groove spacing are determined according to the thickness and spacing of the steel strips and reinforcing ribs on the panel 2, allowing it to be inserted into any rectangular hole on the panel 2. The limiting block 7 is mainly used for stacking tooling platforms. When two or more tooling platforms are stacked and the position of the upper tooling platform needs to be fixed, the limiting block 7 can be placed on the outside of the pad 8 on the support leg 3 of the upper tooling platform. The limiting block 7 is inserted into the rectangular hole on the panel 2 through the U-shaped groove 11 at the bottom, and its upper part blocks the support leg 3.
