Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber preform production, in particular to a carbon fiber preform production device and a use method thereof. Background Art

[0002] Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%. It ranks first among all chemical fibers in terms of high temperature resistance. It is made of acrylic and viscose fibers as raw materials and is made by high-temperature oxidation and carbonization. It is an excellent material for manufacturing high-tech equipment such as aerospace. Carbon fiber is a special fiber composed of carbon elements. It has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance. It has a fibrous and soft appearance and can be processed into various fabrics. However, the existing carbon fiber preform production equipment still has some shortcomings. For example, when the existing carbon fiber preform production equipment is in use, the existing carbon fiber preform production equipment adopts a molding method, which takes a long time to produce and is not very practical. In addition, the carbon fiber preforms produced during use require more manual operations, which is time-consuming and labor-intensive and not very convenient. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN113844056B, a carbon fiber preform production equipment, includes a mixing box, a feeding port cover is provided on one side of the upper end of the mixing box, a brake motor is provided on one side of the lower end of the mixing box, a No. 1 mold is provided on the side of the lower end of the mixing box away from the brake motor, the lower end of the brake motor is connected to a control machine, a conveyor belt is provided on one side of the control machine, a No. 2 mold is provided on the side of the conveyor belt away from the control machine, a heater is provided on the side of the mixing box away from the feeding port cover, a pressurizer is provided on the side of the heater away from the mixing box, a generator is connected to the upper end of the heater and the pressurizer, and the No. 2 mold is placed at the lower end of the pressurizer. This carbon fiber preform production equipment can achieve the purpose of shortening the production cycle, improving the degree of automation, and being more energy-saving and environmentally friendly when used by arranging the No. 1 mold, the No. 2 mold and the CNC yarn cutting machine.

[0004] Although the equipment in the above documents can preform carbon fiber and improve production efficiency, it still has obvious defects in actual use, such as:

[0005] When carbon fiber is pressed through a mold, a lot of preparation processes need to be done. First, in order to facilitate the subsequent removal of the pressed preform, it is necessary to spray the release agent on the surface of the upper and lower molds in advance. At present, most of the workers need to spray manually, and after the pressing is completed, even if the release agent is sprayed in advance, it still needs to be removed with tools such as a spatula. The whole process still requires a lot of manual operation and cannot bring convenience to the workers;

[0016] The present invention also discloses a method for using a carbon fiber preform production device, which specifically comprises the following steps:

[0017] S1. Before use, connect the hose of the material pump to the liquid cylinder, then spray the release agent in the top mold groove of the double-groove lower mold, then spread the carbon fiber material on the inner side of the double-groove lower mold, then start the cylinder to drive the upper mold plate to descend and dock with the double-groove lower mold to press the carbon fiber into shape. In this process, since the teeth of the arc-shaped tooth plate are arc-shaped, they will be pressed back to the inner side of the retraction frame after contacting the gear, and will not mesh with the gear to drive it to rotate. After the upper mold plate descends to the bottom, the positioning guide rod is inserted into the inner side of the limit socket to fix the double-groove lower mold and the rotating column, and then go to step S2;

[0018] S2, after the preform is pressed, the cylinder is started to drive the upper mold plate to rise and separate from the double-groove lower mold. During separation, due to the docking of the positioning guide rod and the limit socket, it can be ensured that the double-groove lower mold will not rotate and deviate due to the pulling force. After the positioning guide rod is pulled out from the inside of the limit socket, the arc-shaped tooth plate is ejected by the first spring and meshes with the gear. Then, under the push of the cylinder, the rotating column and the entire double-groove lower mold are driven to rotate 180 degrees, so that the empty mold groove of the double-groove lower mold is turned upward, and the side with the preform is turned downward. After the cylinder pushes the upper mold plate to be completely located at the upper part, go to step S3;

[0019] S3, after the double-groove lower mold is flipped, the electric telescopic rod is started to pull the rectangular sleeve to the right. The right movement of the rectangular sleeve will drive the material pump to move synchronously through the bending frame. First, the arc head plate will first support the vertical pressure guide plate during the right movement. Under the action of the rotating part, the negative pressure suction frame is pushed up to a horizontal state, and then inserted into the inner side of the concave guide frame and continues to move to the right. Then the upper top seat contacts the horizontal round rod from the bottom and pushes it up. The horizontal round rod is driven by the vertical sliding column to push the negative pressure suction frame and the arc head plate up together and enter the inner side of the mold groove at the bottom of the double-groove lower mold. After the electric telescopic rod is retracted to the limit position, the negative pressure suction frame is completely in contact with the preform, and then the air pump is started to generate suction through the vacuum suction pipe to suck the preform. In this process, the material pump drives the spray frame to move right between the mold rotating frame and the upper mold plate. After the second button is touched by the pressing slide plate, it is pressurized by the second spring. The second button is pressed to start the material pump. At this time, the material pump draws out the release agent and sprays it on the upper mold groove of the double-groove lower mold and the bottom of the upper mold plate through the spray rack. When the material pump moves to the far right, the first button will be pressed by the inner wall of the front guide groove and triggered to turn off the material pump and stop spraying. Then the electric telescopic rod starts to extend and drives the material pump and the upper top seat to move left and reset. The material pump moves directly to the left and leaves between the upper mold plate and the mold rotating frame. After the upper top seat is separated from the horizontal round rod, the third spring will exert a downward pulling force on the horizontal round rod and the vertical sliding column. The pulling force of the third spring drives the negative pressure suction frame to descend and bring out the preform in the lower mold groove. After the arc head support plate is separated from the inclined surface support seat, the negative pressure suction frame flips and tilts and rests on the top of the unloading inclined plate. At this time, the air pump is also closed to allow the preform to slide down from the top of the unloading inclined plate and unload the material. At the same time, during the unloading process, the carbon fiber material is spread flat again in the upper mold groove sprayed with the release agent.

[0020] Preferably, step S1, step S2 and step S3 are repeated in a cycle.

[0021] The present invention provides a carbon fiber preform production device and a method for using the same. Compared with the existing technology, the present invention has the following beneficial effects:

[0022] (1) The carbon fiber preform production equipment and the method of using the same, by combining the pressing mold mechanism and the demoulding spraying mechanism, the arrangement of the two mechanisms can utilize the drive of the cylinder and the electric telescopic rod during the production process, and while completing the carbon fiber pressing, it can also utilize the linkage between the structures to synchronously spray the mold with a release agent, demould and unload the material, and the double-groove lower mold can be rotated in advance, which is convenient for the staff to load the material synchronously, so that the pressing production can be carried out continuously, which is not only convenient to use but also improves the production efficiency.

[0023] (2) The carbon fiber preform production equipment and its use method are characterized by installing a double-slot lower mold on the inner side of the mold rotating frame using a rotating column, and opening a limited position socket and installing gears on the surface of the rotating column, and using it with an arc-shaped toothed plate. The arrangement of these structures can drive the double-slot lower mold to rotate 180 degrees after each rise of the upper mold plate, so that the preform faces downward and the empty mold faces upward, which is convenient for the demoulding and spraying processes to be carried out simultaneously, thereby improving the production efficiency.

[0024] (3) The carbon fiber preform production equipment and its use method are characterized by arranging a negative pressure suction frame below the mold rotating frame, and installing an inclined support seat and a concave guide frame at the bottom of the negative pressure suction frame, and using them in conjunction with an upper top seat, a horizontal round rod and a third spring. The arrangement of these structures can, after the double-slot lower mold is flipped, use the drive of the electric telescopic rod to allow the arc head support plate to abut against the inclined support seat to lift the negative pressure suction frame, and when the upper top seat presses the horizontal round rod, the negative pressure suction frame is in contact with the preform for easy demoulding, and after the negative pressure suction frame descends and tilts, it can be used in conjunction with a material unloading inclined plate to unload the material, thereby improving the overall practicality of the equipment.

[0025] (4) The carbon fiber preform production equipment and the method of using the same are characterized in that the first button and the second button are respectively installed at the bottom of the material pump using a vertical pressure guide plate. The arrangement of these structures can trigger the second button first when the spraying frame moves to the mold slot range of the double-slot lower mold, thereby starting the material pump to accurately spray the double-slot lower mold and the upper mold plate, avoiding spraying the material liquid out of the mold slot, thereby ensuring the cleanliness of the surrounding area of ​​the equipment.

[0041] The present invention also discloses a method for using a carbon fiber preform production device, which specifically comprises the following steps:

[0042] S1. Before use, connect the hose of the material pump 216 to the liquid material cylinder, then spray a release agent in the top mold groove of the double-groove lower mold 106, then spread the carbon fiber material on the inner side of the double-groove lower mold 106, then start the cylinder 103 to drive the upper mold plate 104 to descend and dock with the double-groove lower mold 106 to press the carbon fiber into shape. In this process, since the teeth of the arc-shaped tooth plate 110 are arc-shaped, they will be pressed back to the inner side of the retraction frame 109 after contacting the gear 108, and will not mesh with the gear 108 to drive it to rotate. After the upper mold plate 104 descends to the bottom, the positioning guide rod 117 is inserted into the inner side of the limit socket 107 to fix the double-groove lower mold 106 and the rotating column 105, and then go to step S2;

[0043] S2, after the preform pressing is completed, start the cylinder 103 to drive the upper mold plate 104 to rise and separate from the double-grooved lower mold 106. During the separation, due to the docking of the positioning guide rod 117 and the limiting socket 107, it can be ensured that the double-grooved lower mold 106 will not rotate and deviate due to the pulling force. After the positioning guide rod 117 is pulled out from the inside of the limiting socket 107, the arc-shaped tooth plate 110 is ejected by the first spring 111 and meshes with the gear 108. Then, under the push of the cylinder 103, the rotating column 105 and the entire double-grooved lower mold 106 are driven to rotate 180 degrees, so that the empty mold groove of the double-grooved lower mold 106 is turned upward, and the side with the preform is turned downward. After the cylinder 103 pushes the upper mold plate 104 to be completely located at the upper part, go to step S3;

[0044] S3, after the double-groove lower mold 106 is turned over, the electric telescopic rod 210 is started to pull the rectangular sleeve 211 to move rightward. The rightward movement of the rectangular sleeve 211 will also drive the material pump 216 to move synchronously through the curved frame 215. First, the arc head support plate 214 will first support the vertical pressure guide plate 218 during the rightward movement. Under the action of the rotating part, the negative pressure suction frame 203 is pushed up to a horizontal state, and then inserted into the inner side of the concave guide frame 209 and continues to move rightward. Then, the upper top seat 212 contacts the horizontal round rod 206 from the bottom and pushes it up. The horizontal round rod 206 is driven by the vertical sliding column 202. The negative pressure suction frame 203 and the arc head support plate 214 are pushed up together to enter the inner side of the bottom mold groove of the double-groove lower mold 106. After the electric telescopic rod 210 is retracted to the limit position, the negative pressure suction frame 203 is completely in contact with the preform. Then the air pump 204 is started to generate suction force through the vacuum suction pipe 205 to suck the preform. In this process, the material pump 216 drives the spraying frame 217 to move right to between the mold rotating frame 102 and the upper mold plate 104. After the second button 220 is touched by the support slide plate 114 and pressurized by the second spring 113, the second button 220 is pressed. The material pump 216 is started. At this time, the material pump 216 extracts the release agent and sprays it into the upper mold groove of the double-groove lower mold 106 and the bottom of the upper mold plate 104 through the spray rack 217. When the material pump 216 moves to the rightmost side, the first button 219 will be pressed by the inner wall of the front guide groove 112 and triggered to turn off the material pump 216 to stop spraying. Then the electric telescopic rod 210 starts to extend and drives the material pump 216 and the upper top seat 212 to move left and reset. The material pump 216 directly moves left and leaves between the upper mold plate 104 and the mold rotating frame 102. After the upper top seat 212 is separated from the horizontal round rod 206, The third spring 207 will generate a downward pulling force on the horizontal round rod 206 and the vertical sliding column 202. The pulling force of the third spring 207 drives the negative pressure suction frame 203 to descend and bring out the preform in the lower mold groove. After the arc head support plate 214 is separated from the inclined surface support seat 208, the negative pressure suction frame 203 is flipped and tilted and placed on the top of the unloading inclined plate 115. At this time, the air pump 204 is also closed to make the preform slide from the top of the unloading inclined plate 115 for unloading. At the same time, during the unloading process, the carbon fiber material is spread again in the upper mold groove sprayed with the release agent. Steps S1, S2 and S3 are repeated in a cycle.
