Description
Technical Field
The invention belongs to the technical field of processing tools, and particularly relates to a reinforced wallboard combined core mold tool and a forming process method thereof, which are used for forming a composite material skin/T-shaped stringer integrated structure.
Background
The composite material skin/T-shaped stringer integrated structure means that the skin and the T-shaped stringer structure are integrated, a typical T-shaped stringer structure with flanges is cancelled, and the structure is characterized in that the T-shaped stringer only has a vertical edge and does not have flanges. The reinforced integral wall plate structure has the advantages that: the product has good integral stability and high rigidity, and is not easy to generate distortion.
The T-shaped stringer and the skin of the wallboard are of an integrated structure, and in the process of curing and forming, the main forming technical difficulty is to ensure that each rib and the skin of the wallboard are simultaneously pressed. How to design the forming die structure to ensure the uniform pressure transmission during pressurization is very important. Therefore, if the part is not stressed or is stressed unevenly, quality defects such as layering, looseness, thickness super-difference and the like are easily generated.
Disclosure of Invention
In order to solve the defects in the prior art, the invention provides a combined core mold tool for a stiffened wallboard and a forming process method thereof, so as to ensure that each rib and a skin of the wallboard with a T-shaped stringer and the skin integrated structure of the wallboard are simultaneously pressed.
In order to solve the technical problem, the designed tool adopts a core mold combination mode combining a metal section bar and a rubber soft mold, and plays roles in positioning the stringer and applying pressure in the heating and curing process of the T-shaped stringer and the skin.
The combined core mold tooling for the stiffened wallboard consists of a metal positioning block, an expanded rubber core mold, a metal section and a thin plate. The metal positioning blocks are of a cubic structure, are arranged at intervals along the T-shaped stringer and play roles in edge positioning and skin compaction; a thin plate is arranged between every two adjacent metal positioning blocks, a pair of metal sections are arranged on the thin plate, and an expansion rubber core mold is filled between the pair of metal sections.
Further, the expanded rubber core mold is designed into a trapezoidal funnel structure; the metal section bar is along the long purlin limit of T type and is the type of falling L structure, and a pair of metal section bar constitution funnel structure just places trapezoidal funnel structure's inflation rubber mandrel.
Further, the metal positioning block is made of steel material.
Further, the metal profile is made of a steel material.
Further, the thin plate is made of aluminum alloy or a hardwood plate and has a thickness of 2-3 mm.
The process method for processing and forming the composite skin/T-shaped stringer integrated structure by using the tool comprises the following process flow steps:
s1: and paving and pasting the skin/T-shaped stringer integrated structure. And covering the skin on the skin covering and pasting die, then combining all the T-shaped stringers with the skin, placing metal positioning blocks between the T-shaped stringers and positioning through the metal positioning blocks.
S2: and placing the core mold combination. A metal positioning block is removed every other stringer, a thin plate is placed at the position of the removed metal positioning block, and a metal section and an expanded rubber core mold are placed on the thin plate.
S3: and (5) integrally curing and molding. And sealing the composite material skin/T-shaped stringer integrated structure and the tooling together by using a vacuum bag, and then vacuumizing, curing and forming.
Above-mentioned frock, structure equipment easy operation can guarantee that the long purlin of T type stile is even under pressure, and the covering surface that processing was come out is level and smooth for the product overall stability that processing was come out is good, rigidity is high, be difficult to produce distortion.
