Description

TECHNICAL FIELD

[0001] The utility model relates to co -solidification frock technical field, in particular to a kind of frock of combined stiffened wallboard co -solidification. BACKGROUND

[0002] Since weight reduction can bring higher economic benefits to large aircraft, the amount of composite materials used in the development of aircraft has become a key indicator of the advancement and competitiveness of aircraft. Composite stiffened wallboard structure, as a typical integrated structure, can significantly improve aircraft performance and reduce the number of connecting fasteners.

[0003] Composite stiffened wallboard is a relatively complex structure. For such large size and complex structure, a large number of tooling is required during the molding process. The selection and structure design of the mold material will greatly affect the internal quality and surface state of the composite component.

[0004] Currently, co -solidification frock is generally welded by multiple plates, and then the plates formed by welding are welded with the frame to form a frock. Since multiple plates are welded together, deformation is likely to occur between adjacent two plates. After multiple uses, i.e. after multiple thermal expansion and contraction operations, the frock formed by welding is also prone to deformation. The plates with deformation cannot meet the production requirements, and the stability of each plate is poor. UTILITY MODEL CONTENT

[0007] Preferably, the spacer has a C-shaped cross section, bolt holes are formed on both sides of the spacer, one side of the spacer is arc-shaped for fitting the inner wall of the plate, and the other side is used to connect the outer wall of the frock main body.

[0008] Preferably, the plurality of plates are evenly distributed along the length direction of the frock main body.

[0009] Preferably, a plurality of spacers are installed on the inner wall of each plate, and the number of spacers is several, and the plurality of spacers are evenly distributed along the edge of the frock main body.

[0010] Preferably, a gasket is connected between the spacer and the frock main body.

[0011] Preferably, the spacer is further provided with a relief hole.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] 1. A plurality of spacers are installed between each die plate and the die body, and the plurality of die plates and spacers provide support, ensuring the overall rigidity of the die, so that no obvious deformation occurs during the laying process, and the stress is evenly distributed during the subsequent laying operation, and the stability is high.

[0014] 2. The die body is formed by a plurality of die plates, and each die plate is independently connected to the die body by a plurality of spacers. The die plates installed on the die body can be adjusted in position, and the die plates can be connected in an abutting manner or with a gap between adjacent die plates. Each die plate can be adjusted independently, has good adaptability, can be fine-tuned, and is easy to install. The die plates can be flexibly adjusted to ensure that the state meets the requirements, and the overall inner and outer bags are punched during curing to ensure air tightness.

[0020] The technical scheme of the utility model will be described below in conjunction with the drawings in the specification and specific embodiments. Figures 1-4

[0021] Embodiment:

[0022] For example, Figure 1 , Figure 2 , Figure 3 and Figure 4 ​The utility model provides a kind of combined type reinforced wallboard co-curing's tooling, including the tooling main body 2 made of steel welding into barrel, tooling main body 2 is connected on bottom plate 3, tooling main body 2 outer edge is also connected with several profile plates 1, profile plate 1 is connected with tooling main body 2 by spacer 4 between profile plate 1 and tooling main body 2.

[0023] The cross section of the spacer 4 is C-shaped, and bolt holes 5 are formed on both sides of the spacer 4. One side of the spacer 4 is arc-shaped for fitting the inner wall of the profile plate 1, and the other side is used to connect the outer wall of the tooling main body 2. The several profile plates 1 are evenly distributed along the length direction of the tooling main body 2. The inner wall of each profile plate 1 is provided with a plurality of spacers 4. The number of spacers 4 is several, and the several spacers 4 are evenly distributed along the edge of the tooling main body 2. The spacer 4 and the tooling main body 2 are further connected with a gasket 6. The spacer 4 is further provided with a clearance hole 7.

[0024] The tooling main body 2 is connected to the bottom plate 3 by welding or other methods. Since the tooling main body 2 is in the form of a barrel, multiple profile plates 1 need to be installed on the tooling main body 2 to ensure that the entire outer surface of the tooling main body 2 is covered with profile plates 1. Multiple spacers 4 are installed on each profile plate 1. Each spacer 4 is compensated by a gasket 6 to increase the connection tightness and stability between the profile plate 1 and the tooling main body 2.

[0025] Multiple spacers 4 are further provided between the profile plate 1 and the tooling main body 2. Since the profile plate 1 is arc-shaped, the side curvature of the spacers 4 installed at different positions is not the same. The appropriate spacers 4 are selected according to the curvature of the inner wall of the profile plate 1 at the required installation position. Each profile plate 1 can be adjusted individually, and the adaptability is good.

[0026] Each profile plate 1 can be connected to the tooling main body 2 through spacers 4 and bolts after being butt-jointed. A gap is left between the two adjacent profile plates 1, and then the spacers 4 and bolts are connected to the tooling main body 2. The connection can be fine-tuned, the profile plate 1 is installed more conveniently, and the state can be flexibly adjusted to meet the requirements.

[0027] Then install multiple spacers 4 with different curvatures between the frame and each profile plate 1, and fix and connect them through bolts. A gap is left between the spacer 4 and the frame during connection. Insert a gasket 6 into the gap, and then further tighten the bolts connected between the frame and the spacer 4. The connection tightness and stability can be increased. The corresponding spacers 4 can be replaced according to different size specifications, and the gasket 6 can be compensated later. The adaptability is extensive, and the versatility is strong.

[0028] The arc-shaped surface of each cushion block 4 is attached to the inner wall of the mold plate 1, and the cushion blocks 4 are uniformly arranged along the inner wall of the mold plate 1, so that the plurality of cushion blocks 4 can play a supporting and stabilizing role, thereby effectively solving the problem of easy deformation of the mold surface, and the tooling can guarantee air tightness, high stability of sealing, wide adaptation range, strong adaptability, simple operation and high stability.

[0029] The tooling is also more convenient and fast when demolding, the profile and the mold plate 1 are attached to each other, only the bolt needs to be loosened to demold the longeron upward, so that the longeron and the mold plate 1 are demolded upward together, and then the mold plate 1 and the cushion blocks 4 connected thereon can be removed subsequently.

[0030] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
