Description

Technical Field

[0001] The utility model relates to the technical field of composite structure forming tooling, in particular to a large-size thin sandwich composite structure forming tooling. Background Art

[0002] The history of composite materials can be traced back to ancient times. Clay reinforced with rice or wheat straw, which has been used since ancient times, and reinforced concrete, which has been used for hundreds of years, are both made of two materials. The needs of the aviation industry led to the development of glass fiber reinforced plastics, and the term composite materials has since emerged. High-strength and high-modulus fibers such as carbon fiber, graphite fiber, and boron fiber, as well as aramid fiber and silicon carbide fiber, have been developed. These high-strength, high-modulus fibers can be combined with non-metallic matrices such as synthetic resins, carbon, graphite, ceramics, and rubber, or metal matrices such as aluminum, magnesium, and titanium, to form unique composite materials.

[0003] When using the current composite structure forming tooling, the materials to be composited are stacked together and softened by heating, thereby facilitating composite plasticization of the multiple materials. After the materials are softened, the upper mold moves downward and cooperates with the bottom mold to form the multiple stacked materials.

[0004] During the use of traditional composite molding tooling, workers directly stack multiple materials together. Some dust will adhere to the surface of the materials during stacking or transportation. The molding tooling does not clean the dust, and the dust will be between the two different materials, resulting in poor connection effect after the materials are composited together, thereby affecting the use strength of the composite structure.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0022] In traditional composite molding tooling, workers directly stack multiple materials together during the process of stacking or handling. Dust will adhere to the surface of the materials during stacking or handling. The molding tooling does not clean the dust, and the dust will be trapped between the two different materials, resulting in poor connection after the materials are combined, thus affecting the strength of the composite structure.

[0023] In view of this, the utility model provides a large-size thin sandwich composite structure forming tooling, which uses an electric heating plate to heat and soften the multi-layer composite material, and the hydraulic cylinder drives the top mold to move downward. The top mold cooperates with the tooling body to shape the multi-layer composite material. The cleaning device cleans the surface of the composite material before shaping to prevent dust from being between the two materials, so that the connection effect after the materials are compounded together is better and will not affect the use strength of the composite structure.

[0024] Example 1: By Figure 1 、 2, 3, 4 and 5 show that a large-size thin sandwich composite structure forming tool comprises a tool body 1, the interior of the tool body 1 is rotatably connected to two rollers 3 through bearings, the front of the two rollers 3 is detachably connected to two first servo motors 4, the outer walls of the two first servo motors 4 are detachably connected to the inner wall of the tool body 1, a plurality of electric heating plates 7 are installed inside the tool body 1, a bending plate 8 is installed on the top of the tool body 1, a hydraulic cylinder 9 is installed on the inner wall of the bending plate 8, and a top mold 10 is installed at the bottom of the hydraulic cylinder 9. The large-size thin sandwich composite structure forming tool also includes: a cleaning device 2, installed inside the tool body 1; an alignment device 5, arranged above the tool body 1; a demoulding device 6, installed inside the tool body 1; wherein the cleaning device 2 can clean the surfaces of multiple composite materials, the alignment device 5 can align multiple composite materials on one side, and the demoulding device 6 facilitates the demoulding of multiple composite structures after molding;

[0025] During the specific implementation, it is worth noting that the model of the first servo motor 4 is ECMA-E11320RS, the model of the electric heating plate 7 is YK-3, and the model of the hydraulic cylinder 9 is MOB. The first servo motor 4 drives the roller 3 to rotate, and the roller 3 drives the composite material to move. The cleaning device 2 cleans the surface of the composite material, the alignment device 5 aligns one side of the cleaned composite material, and the demolding device 6 demolds the formed composite structure.

[0026] Furthermore, a limit plate 11 is installed on one side of the tool body 1;

[0027] In the specific implementation process, it is worth noting that the limiting plate 11 limits the moving direction of the composite material so that the composite material can enter the interior of the tooling body 1;

[0028] Specifically, when using the large-size thin sandwich composite structure forming tooling, the limit plate 11 limits the moving direction of the composite material, allowing the composite material to enter the interior of the tooling body 1. When the first servo motor 4 is working, it drives the roller 3 to rotate, and the roller 3 squeezes the plate into the interior of the tooling body 1. The cleaning device 2 cleans the dust on the surface of the composite material, the alignment device 5 aligns the composite material to one side, the electric heating plate 7 heats and softens the composite material, and the hydraulic cylinder 9 drives the top mold 10 to move downward when working. The top mold 10 cooperates with the tooling body 1 to plasticize the composite structure, and the demolding device 6 facilitates the demolding of the formed composite structure.

[0029] Example 2: By Figure 1 、 2As shown in Figure 3, the cleaning device 2 includes: an air inlet pipe 201, which is installed inside the tooling body 1; two cleaning scrapers 202 are provided, both of which are installed inside the tooling body 1; a filter box 203, which is installed inside the tooling body 1 and is connected to one end of the air inlet pipe 201; a filter plate 204, which is installed inside the filter box 203; a vacuum pump 205, which is detachably connected to the inside of the tooling body 1, and one end of which extends to the inside of the filter box 203; an exhaust pipe 206, which is installed at the output end of the vacuum pump 205 and is fixedly connected to the inside of the tooling body 1; wherein, when the vacuum pump 205 is working, the air inside the filter box 203 is extracted and turned into a negative pressure state, and the cleaning scraper 202 scrapes the dust on the surface of the composite material and sends the dust into the inside of the filter box 203 through the air inlet pipe 201, and the filter plate 204 filters the dust;

[0030] During the specific implementation, it is worth noting that the cleaning scraper 202 is made of rubber, the mesh size of the filter plate 204 is not specifically limited and can be used as long as it meets the requirements. The model of the vacuum pump 205 is 2X-4G. When the vacuum pump 205 is working, it extracts the air from the filter box 203, creating a negative pressure state inside the filter box 203. The cleaning scraper 202 scrapes the dust off the surface of the composite material, and the air communicates with the dust and enters the filter box 203 through the air inlet pipe 201.

[0031] Specifically, based on the above-mentioned embodiment 1, the external power supply of the vacuum pump 205 is turned on. When the vacuum pump 205 is working, the air inside the filter box 203 is extracted through the exhaust pipe 206, so that a negative pressure state temporarily appears inside the filter box 203. When the composite material moves, the cleaning scraper 202 scrapes off the dust on the surface, and the air around the inlet pipe 201 is connected to the dust and sucked into the interior of the filter box 203. The filter plate 204 adsorbs the dust on the surface, thereby completing the removal of dust on the surface of the composite material.

[0032] Example 3: By Figure 1 、 2 As shown in Figures 4 and 5, the alignment device 5 includes: a cylinder 501, installed inside the tool body 1; a slider 502, installed at the output end of the cylinder 501; a slant plate 503, slidably engaged with the upper portion of the slider 502 and rotatably connected to the inner side of the tool body 1 via a pin; and a baffle 504, installed above the slant plate 503. The cylinder 501 adjusts the slant plate 503 from a horizontal state to an inclined state via the slider 502.

[0033] In the specific implementation process, it is worth noting that the model of the cylinder 501 is SCA2-CB-100B-300-T0H3-DY. The cylinder 501 drives the inclined plate 503 to rotate through the slider 502, adjusting the inclined plate 503 to a tilted state;

[0034] Specifically, based on the above-mentioned embodiment 1, when the cylinder 501 is working, the slider 502 drives the inclined plate 503 to rotate, and the inclined plate 503 is adjusted from a horizontal state to an inclined state. After the composite material is cleaned, it is restricted by the inclined plate 503 and slides into the inside of the inclined plate 503. It is restricted by the baffle 504, so that one side of the composite material close to the baffle 504 is aligned, which is convenient for subsequent processing.

[0035] Example 4: By Figure 1 、 2 , 4 and 5 show that the demoulding device 6 includes: a tooth plate 601, which is movably connected to the inside of the tooling body 1; a plurality of top plates 602 are provided, all of which are installed above the tooth plate 601 and are movably connected to the inner wall of the tooling body 1; a round rod 603, which is movably connected to the inside of the tooth plate 601; a cam 604, which is installed on the outer wall of the round rod 603 and is rotatably connected to the inner wall of the tooling body 1; a second servo motor 605, which is detachably installed on the front face of the cam 604 and is detachably connected to the inner wall of the tooling body 1; wherein, when the second servo motor 605 is working, the tooth plate 601 is driven to move upward by the round rod 603 inside the cam 604, and the tooth plate 601 drives the top plate 602 to move upward;

[0036] In the specific implementation process, it is worth noting that the model of the second servo motor 605 is SM80-D601930. When the second servo motor 605 is working, it drives the round rod 603 to move through the cam 604, and the round rod 603 drives the top plate 602 to move upward through the tooth plate 601.

[0037] Specifically, on the basis of the above-mentioned embodiment 1, the external power supply of the second servo motor 605 is turned on. When the second servo motor 605 is working, it drives the cam 604 to rotate, the cam 604 drives the round rod 603 to move, the round rod 603 drives the tooth plate 601 to move, the tooth plate 601 drives the top plate 602 to move upward, and the top plate 602 pushes out the composite structure that has been formed and cooled inside the tooling body 1. When multiple top plates 602 push out the composite structure, the force is evenly distributed, so as to prevent the composite structure from being deformed when demolding.
