Description

Technical Field

[0001] The present invention relates to the field of manufacturing textiles, and particularly to a pre-shaped carbon fiber fabric forming device. Background Art

[0002] Carbon fiber materials are commonly used lightweight and high-strength materials in the manufacturing industry and are widely applied. They are made by mixing carbon fiber fabrics with resin organic materials and then fixing them into shape. The commonly used method in the industry is to manually embed the pre-impregnated carbon fiber fabric into the interior of a mold, and then use other equipment for high-temperature and high-pressure shaping. Due to the low efficiency of manually fitting the carbon fiber fabric, the price of carbon fiber materials has remained high for a long time. Secondly, for the carbon fiber fabric manually fitted, some edges and corners are prone to insufficient fitting during detail processing, resulting in the inability of the formed carbon fiber to be shaped standardly.

[0003] For example, a piercing and compressing device for forming a three-dimensional carbon fiber fabric proposed in CN201510372529.0 includes an upper driving device, a piercing device, and a mobile workbench; the upper driving device is driven by a three-phase asynchronous motor, and the small pulley drives the large pulley through a V-belt; the large pulley is fixedly connected to one end of a clutch, and the clutch is key-connected to one end of a crankshaft. The crankshaft is fixed to the upper plate through four bearing seats, and a crankshaft connecting rod is fixed in the middle of the crankshaft. The lower end is connected to the upper piercing plate of the piercing device through a connecting seat; the piercing template is driven to complete the piercing action by the rotation of the three-phase asynchronous motor; the moving plate is sleeved on four optical axes through linear bearings at the four corners and is connected to a trapezoidal lead screw through a lead screw nut, and a mobile workbench is fixed on the moving plate; this invention is used for the piercing and compressing of laminated woven carbon cloth, realizing the automation of the piercing and pressurizing and densifying functions of laminated woven carbon cloth, improving work efficiency and reducing the labor intensity of workers, but it does not solve the above problems.

[0004] The present invention can initially fit the mold and the carbon fiber fabric through a provided fitting device, and then make the mold and the carbon fiber fabric fit fully through a provided extrusion device and fixing device, so that the carbon fiber fabric is formed more accurately and standardly.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0028] Next, a pre-shaped carbon fiber fabric forming device according to an embodiment of the present invention will be described with reference to the accompanying drawings. As Figure 1 - Figure 7 shown, the pre-shaped carbon fiber fabric forming device includes a bottom plate 1. There are supporting feet above the bottom plate 1. A cover plate 2 is hinged above the bottom plate 1. There is a handle above the cover plate 2. The pre-shaped carbon fiber fabric forming device further includes: a fitting device provided above the bottom plate 1 for fitting the carbon fiber fabric B with the mold A to perform preliminary positioning and shaping; an extrusion device provided below the fitting device, which can make the carbon fiber fabric B fully fit with the mold A by extrusion; a fixing device provided above the fitting device, which can fix the positioning mold A to prevent the mold A from shifting.

[0029] As Figure 3 、 Figure 4 and Figure 5As shown in the figure, the pre-shaped carbon fiber fabric forming device includes a laminating device. The laminating device includes a vacuum pump 3, a film 5, a mounting plate 6, and a sealing plate 9. The vacuum pump 3 is arranged in front of the bottom plate 1, and the air extraction hole of the vacuum pump 3 faces the bottom plate 1. There are two films 5, which are made of elastic materials. One end of the upper film 5 is connected above the cover plate 2, and the other end is provided with a mounting plate 6. One end of the lower film 5 is connected above the bottom plate 1, and the other end is provided with a mounting plate 6. There are card holes on both sides of the mounting plate 6, and an arc structure is provided in the middle of the mounting plate 6. The arc structures of the upper and lower mounting plates 6 can be combined into a hole and connected to the air extraction hole of the vacuum pump 3. There are tenons 7 on the cover plate 2 and the bottom plate 1 for clamping the mounting plate 6. Vent holes 8 are opened on the cover plate 2 and the bottom plate 1 for communicating with the outside. The sealing plate 9 is arranged above the bottom plate 1 and below the cover plate 2. The sealing plate 9 is of a ring structure. There is a through hole at the rear of the sealing plate 9 for communicating the inside and outside of the sealing plate 9, and a notch is provided in front of the sealing plate 9.

[0030] In a specific embodiment: When in use, the film 5 is stretched through the mounting plate 6 and installed on the corresponding tenons 7. Then, the carbon fiber fabric B is placed on the film 5 above the bottom plate 1, and the mold A is placed on the carbon fiber fabric B. Then, the cover plate 2 is covered on the bottom plate 1, so that the film 5 below the bottom plate 1 covers above the mold A, and the arc structures of the upper and lower mounting plates 6 can be combined into a hole and connected to the air extraction hole of the vacuum pump 3. Then, the vacuum pump 3 is started through an external power supply, and the film 5 forms a bag shape through the sealing plate 9 with a notch in the front, and the vacuum pump 3 evacuates the air, so that the film 5 pushes the carbon fiber fabric B to fit the mold A.

[0031] As Figure 3 , Figure 5 and Figure 7 shown in the figure, the pre-shaped carbon fiber fabric forming device includes an extrusion device. The extrusion device includes a top block 13, a support plate 16, and a connecting pipe 4. The top block 13 is fixed on the bottom plate 1. The top block 13 is located below the mold A. The top block 13 fits the shape of the mold A. The edge of the top block 13 is a plate-like structure. There is an air inlet hole 15 in the middle of the top block 13. The lower part of the air inlet hole 15 is connected to the air outlet of the vacuum pump 3 through the connecting pipe 4. The upper end of the air inlet hole 15 is in a groove shape. The support plate 16 is installed on the top block 13 and located in the groove of the air inlet hole 15, so that an annular gap is formed at the upper end of the air inlet hole 15. There are multiple air guiding grooves 14 above the top block 13. The lower ends of the air guiding grooves 14 penetrate the top block 13. There are air chambers 17 connecting the air guiding grooves 14 at the corners of the upper end edge of the top block 13.

[0032] In a specific embodiment: When in use, the top block 13 will lift the film 5 above the bottom plate 1 and fit it with the carbon fiber fabric B, so that the carbon fiber fabric B fits inside the mold A and the top block 13 is embedded inside the carbon fiber fabric B.

[0033] As Figure 1 and Figure 6As shown in the figure, the pre-shaped carbon fiber fabric forming device includes a fixing device. The fixing device includes a tube body 10, a top column 11, and a spring 12. The tube body 10 is arranged above the cover plate 2. The top column 11 is slidably installed in the tube body 10. The spring 12 is arranged at the upper end of the top column 11. The upper part of the tube body 10 is connected to the air outlet of the vacuum pump 3 through a connecting pipe 4. The lower end of the top column 11 is a ball head structure, and the upper end of the top column 11 is a piston head structure.

[0034] In a specific embodiment: During use, the vacuum pump 3 inflates the tube body 10, so that the lower end of the top column 11 contacts the film 5 below the cover plate 2, thereby making the film 5 and the mold A below the film 5 fully fit with the carbon fiber fabric B, and positioning and limiting the mold A and the carbon fiber fabric B to prevent the film 5 from being evacuated to affect the fitting of the mold A and the carbon fiber fabric B.

[0035] After the mold A is positioned by the fixing device, the top block 13 embedded in the inner side of the carbon fiber fabric B is inflated by the vacuum pump 3. At the same time, the support plate 16 will support the carbon fiber fabric B above, so that the air flow flows into the air guide groove 14 from the air inlet hole 15. The air flow in the air guide groove 14 will squeeze the carbon fiber fabric B, making the carbon fiber fabric B better fit the mold A. At the same time, the air flow enters the air chamber 17 at the edge to fully fit the carbon fiber fabric B at the corner, so that the carbon fiber fabric B is formed more accurately and standardly.

[0036] Working principle: During use, the film covering 5 is stretched by the mounting plate 6 and installed on the corresponding tenon 7. Then, the carbon fiber fabric B is placed on the film covering 5 above the bottom plate 1, and the mold A is placed on the carbon fiber fabric B. Then, the cover plate 2 is covered on the bottom plate 1, so that the film covering 5 under the bottom plate 1 covers the upper part of the mold A, and the arc-shaped structures of the mounting plates 6 on the upper and lower sides can be combined into a duct and connected to the air extraction hole of the vacuum pump 3. Then, the vacuum pump 3 is started by an external power supply. The film covering 5 forms a bag shape through the sealing plate 9 with a notch in the front, and the vacuum pump 3 evacuates the air, so that the film covering 5 pushes the carbon fiber fabric B to fit the mold A. Then, the top block 13 will lift the film covering 5 above the bottom plate 1 and fit it with the carbon fiber fabric B, so that the carbon fiber fabric B fits inside the mold A, and the top block 13 is embedded in the inner side of the carbon fiber fabric B. Then, the vacuum pump 3 inflates the pipe body 10, so that the lower end of the top column 11 contacts the film covering 5 under the cover plate 2, so that the film covering 5 and the mold A under the film covering 5 are fully fitted with the carbon fiber fabric B, and the mold A and the carbon fiber fabric B are positioned and limited, preventing the film covering 5 from forming an influence on the fitting of the mold A and the carbon fiber fabric B when evacuating the air. Then, after the mold A is positioned by the fixing device, the top block 13 embedded in the inner side of the carbon fiber fabric B is inflated by the vacuum pump 3. At the same time, the support plate 16 will support the upper carbon fiber fabric B, so that the air flow flows into the air guide groove 14 from the air inlet hole 15. The air flow in the air guide groove 14 will squeeze the carbon fiber fabric B, so that the carbon fiber fabric B fits the mold A better. At the same time, the air flow enters the air chamber 17 at the edge to fully fit the carbon fiber fabric B at the corner and turning, so that the carbon fiber fabric B is formed more accurately and standardly.
