Description

Technical Field

[0001] This invention relates to the field of honeycomb panel production molds, and in particular to a production mold and method for double-arc honeycomb panels. Background Technology

[0002] Honeycomb panel structures have excellent bending and shear resistance, and are widely used in transportation fields such as aviation, high-speed rail, and new energy vehicles.

[0003] A double-arc honeycomb panel mold is a specialized forming tool used to produce honeycomb panels with a special hyperboloid structure. This mold combines precision machining technology and composite material molding processes, enabling the efficient and precise manufacture of lightweight, high-strength honeycomb structure panels with excellent mechanical properties.

[0004] However, existing honeycomb panel production molds have the following problems during use: During the honeycomb panel forming process, the curvature is made after the honeycomb panel is formed. The curvature cannot be formed directly, as the forming process is relatively slow. Making the curvature after the honeycomb panel is formed can easily damage the honeycomb panel. In addition, the honeycomb panel also needs to be bonded with aluminum plates, which is quite troublesome. When making curved shapes, machines are often used for pressing. However, machine pressing makes it difficult to control the precision of the curve and the degree of curvature. Moreover, the production of the curve needs to be coordinated with the forming time. If the forming of the curve is not timely enough, the quality of the honeycomb panel will be poor. Summary of the Invention

[0005] The purpose of this invention is to provide a production mold and method for double-arc honeycomb panels, and to provide a honeycomb panel production mold that is fast to form and simple to manufacture.

[0006] This invention is a production mold for a double-arc honeycomb panel, comprising two mold frames, an upper mold, and a lower mold adapted to the upper mold, wherein the upper mold and the lower mold are both installed within the mold frames; The lower mold has a movable plate inside, and several mandrels are fixed inside the lower mold. Several grooves are provided on one side of the movable plate, and the mandrels pass through the grooves one by one. The movable board is made of a soft, flexible material. Both the upper mold and the lower mold have openings on one side, and the openings are located on both sides of the mandrel. Each side of the movable plate is provided with a sliding groove, and each sliding groove is provided with an arc adjustment component. Each side of the lower mold is provided with a height adjustment component, and the height adjustment component is connected to the arc adjustment component.

[0007] The arc adjustment assembly includes a slide rod, a connecting rod, an adjuster, an adjusting column, and a moving rod. The slide rod is disposed inside a slide groove. Side plates are provided on both sides of the movable plate. One end of the connecting rod is connected to one side of the slide rod, and the other end of the connecting rod is connected to one side of the adjusting column. The adjusting column is movably disposed inside the adjuster. The adjuster is hollow inside and has movable grooves on both sides. The two moving rods are respectively connected to both sides of the adjusting column and are movably disposed inside the movable grooves. The regulator has two U-shaped ends, allowing the adjusting column to move within it. The movement of the two moving rods can drive the adjusting column to move in different directions.

[0008] The height adjustment assembly includes a motor, a lead screw, a moving block, a first slide rail, and a first slider. The motor is located on one side of the lower mold. The lead screw is movably located on one side of the lower mold via a limiter. The output end of the motor is connected to one end of the lead screw via a reducer. The moving block is movably located on the lead screw. The first slide rail is located on one side of the lower mold. The first slider is movably located inside the first slide rail. One side of the first slider is connected to the moving block, and the other side of the first slider is connected to an adjuster.

[0009] A positioning component is provided on the upper mold; The positioning assembly includes a second slide rail, a second slider, a mounting base, a positioning telescopic rod, an electromagnetic block, and an adsorption block. The second slide rail is disposed on one side of the upper mold, the second slider is movably disposed inside the second slide rail, the second slider corresponds to the first slider, the mounting base is disposed on one side of the second slider, the positioning telescopic rod is mounted on one side of the mounting base, the electromagnetic block is disposed at the moving end of the positioning telescopic rod, and the adsorption block is disposed on one side of the moving rod, the electromagnetic block and the adsorption block are adapted to each other.

[0010] Each side of the upper and lower molds is provided with a set of positioning blocks and a set of positioning holes, and the positioning blocks and positioning holes cooperate with each other.

[0011] A vacuum pumping component is provided on each side of the upper mold; Among them, the vacuuming component can work after the upper mold and the lower mold are closed to evacuate the mold cavity to reduce air holes; After the honeycomb panel is formed, a vacuum is applied, which allows the aluminum plate to adhere to the honeycomb panel.

[0012] The lower die is provided with several limiters, and there are two lead screws connected by several limiters and a connecting shaft.

[0013] The groove has a regular hexagonal structure, and the mandrel structure is adapted to it; The mandrel enables the sheet material to be shaped into a honeycomb structure.

[0014] Each of the openings is equipped with a movable door, and the movable door has two handles. The movable door seals the opening, allowing the aluminum plate to be bonded to the opening during the bonding process.

[0015] A method for producing a double-arc honeycomb panel includes the following steps: S1. Honeycomb panel fabrication; The upper and lower molds are closed, and then the raw materials are placed into the mold; S2, Positioning; During the process of closing the upper and lower molds, the positioning component of the upper mold also moves, causing the positioning telescopic rod to move, so that the electromagnetic block and the adsorption block can be combined and adsorbed to complete the positioning of the upper and lower molds. S3, Adjust position; During the process of putting raw materials into the mold, the motor is started, which drives the lead screw to rotate. The rotation of the lead screw drives the moving block to move, which in turn drives the first slider to move in the first slide rail. The first slider drives the adjuster to move, and moves to the place where the arc is made. S4. Adjust the curvature; After the position is adjusted, the two positioning telescopic rods are activated, which drive the electromagnetic blocks to move, and drive the moving rods on the two adjusters to move in two different directions. The movement of the moving rods causes the adjusting column to move in the adjuster, and then the sliding rod drives the movable plate to bend to one side. At this time, the other sliding rod drives the movable plate to bend to the other side, forming a double arc honeycomb plate. S5, aluminum plate bonding; After molding, an aluminum plate is placed through the opening, and vacuum heating is used to adsorb the aluminum plate and make it adhere to the honeycomb panel.

[0016] The present invention has the following beneficial effects: This invention activates two positioning telescopic rods after the position is adjusted, which in turn move the electromagnetic blocks and the moving rods on the two adjusters in two different directions. The movement of the moving rods causes the adjusting column to move within the adjuster, and then the sliding rods cause the movable plate to bend to one side. At the same time, the other sliding rod causes the movable plate to bend to the other side. While controlling the positioning, the positioning telescopic rods can also control the curvature of the honeycomb panel in a timely manner, and can adjust the curvature in a timely manner during the forming stage, thereby improving the quality of the honeycomb panel.

[0017] This invention allows for fine-tuning of the curvature of the double-arc honeycomb panel by adjusting the fit between the upper and lower molds using a positioning telescopic rod. During curvature adjustment, if the fit between the upper and lower molds changes, the internal curvature will also change, allowing for timely adjustment of the curvature.

[0018] This invention is activated by two positioning telescopic rods, which respectively drive the electromagnetic blocks to move, causing the moving rods on the two adjusters to move in two different directions. The movement of the moving rods causes the adjusting column to move within the adjuster, and then the sliding rod drives the movable plate to bend to one side. At the same time, the other sliding rod drives the movable plate to bend to the other side. The adjusting column can be moved on both sides of the adjuster, allowing the movable plate to bend to the desired position. It can bend not only to the opposite side but also to the same side. The distance the adjusting column moves within the adjuster is used to adjust the curvature, thus improving the control over the accuracy of the curvature.

[0019] This invention achieves positioning of the upper and lower molds by moving the positioning component of the upper mold during the mold closing process, causing the positioning telescopic rod to move and the electromagnetic block to combine with the adsorption block. The positioning telescopic rod not only controls and adjusts the curvature, but also extends and retracts during the mold closing process according to the degree of fit between the upper and lower molds to facilitate positioning.

[0020] This invention allows for the starting of a motor during the process of placing raw materials into a mold. This motor drives a lead screw to rotate, which in turn moves a moving block. This moving block then moves a first slider within a first slide rail. The first slider then moves an adjuster to the location where the curvature is to be formed. This allows for position adjustment before molding, facilitating both molding and curvature adjustment, thus improving production efficiency.

[0021] This invention features a movable plate with several core rods fixedly installed inside the lower mold. Several grooves are provided on one side of the movable plate, through which the core rods pass. The movable plate in the mold can be bent, allowing for direct arc forming, thereby increasing the forming speed of double-arc honeycomb panels and improving the production efficiency of honeycomb panels.

[0022] This invention features openings on both the upper and lower mold sides, located on opposite sides of the core rod. This allows for the rapid placement of aluminum plates through these openings after the honeycomb panel is formed. The aluminum plates are then bonded to the honeycomb panel via vacuum heating and adsorption. This timely bonding process, which occurs immediately after the honeycomb panel is formed, not only reduces manufacturing difficulty but also enhances the quality of the honeycomb panel.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
