Description

Technical Field

[0001] The present invention relates to the technical field of composite plate processing, and in particular to a glass fiber and carbon fiber composite plate forming device and forming process. Background Art

[0002] Glass fiber and carbon fiber composite boards are a new type of material that is widely used in the automotive and other fields. When forming carbon fiber composite boards, the carbon fiber layers are generally composited and connected to the skeleton board or the inner core board. Currently, hot pressing and other methods are generally used for forming.

[0003] Currently, the hot pressing operation is generally performed directly after the attachment, without bending and pressing, resulting in poor internal composite. This is easy to cause cracking or delamination in the composite board when it is subsequently pressed into the required shape, especially in the case of complex curved surfaces. Over time, problems such as outer skin damage will occur, affecting the service life;

[0004] In addition, a large amount of heat is easily wasted during the hot pressing process, resulting in a large amount of resource waste in the mass production process and a significant increase in the overall cost. Summary of the Invention

[0015] A glass fiber and carbon fiber composite material plate forming process comprises the following steps:

[0018] S3. Hot-pressing the stacked fiberboards into shape, and then bending and pressing them.

[0019] Compared with the existing technology, the advantages of the present invention are:

[0020] 1. An expansion and extrusion mechanism is installed inside the upper expansion tank. As the temperature rises, the expansion liquid absorbs heat, thereby changing itself from liquid to gas. This process is accompanied by uniform diffusion of heat and an increase in internal pressure. The expansion and extrusion mechanism can use the pressure brought by vaporization expansion to complete the hot pressing process, thereby ensuring both pressure and temperature.

[0021] 2. Under the action of pressure, the peripheral extrusion block begins to move downward gradually, so that the peripheral extrusion block can contact the plate to be processed, so that the plate to be processed can be effectively hot-pressed. The hot-pressing intensity is positively correlated with the heating temperature and the injection amount of the expansion fluid. The control of pressure and temperature is consistent, so the overall control adjustment is very easy and reliable.

[0022] 3. The spray pipe is equipped with a built-in atomizing nozzle. The spray pipe guides the expansion liquid inside the liquid storage tank into the upper expansion tank, and uses the built-in atomizing nozzle to achieve atomization and diffusion of the expansion liquid, so that the expansion liquid can be spread in fine particles, thereby enabling the expansion liquid to absorb heat faster and more evenly, and then vaporize and expand, which is conducive to the rapid diffusion and rise of heat inside the upper expansion tank, and also enables the pressure inside the upper expansion tank to be quickly increased, so as to improve the overall hot pressing efficiency;

[0023] 4. The peripheral heating pipe is also used to transfer heat, so that the temperature inside the peripheral heating cavity can be quickly increased, so that the bottom temperature of the peripheral extrusion block can be effectively increased, thereby ensuring the temperature of the hot pressing process. The central heating pipe quickly transfers heat to the central heating cavity, thereby effectively increasing the temperature of the central pressing block, thereby keeping the hot pressing temperature of the entire upper hot pressing surface consistent;

[0024] 5. After the pressure is reached, the central pressing block can be compressed alone and apply pressure to the center of the plate. The lower top block has space to move downward, so that the lower area of ​​the center of the plate makes room. The plate can be squeezed by the central pressing block and bend downward from the center, realizing the extrusion treatment of the lower bending of the plate, improving the strength of the plate, improving the pressing effect, and improving the uniformity of the interior of the composite plate after forming, ensuring better composite performance inside the composite plate, improving the toughness of the composite plate, and ensuring the performance after subsequent complex forming.

[0025] 6. The heat exchange sleeve can be forced to move along the heat exchange column, and the existence of the thread makes the heat exchange sleeve rotate during its movement, thereby driving the rotary blades on it to rotate. The rotation and stirring of the rotary blades stir the water flow inside the lower support box, thereby improving the heat exchange efficiency and the preheating effect of the plate.

[0043] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0044] Example

[0045] Reference Figure 1-10A glass fiber and carbon fiber composite material board forming device includes a supporting bottom box 1, the supporting bottom box 1 is filled with water to increase its own weight and improve the overall stability. The water can be reused later. The side wall of the supporting bottom box 1 is fixed with a supporting side box 2, the upper end of the supporting bottom box 1 is fixed with a lower supporting box 3, the side wall of the supporting side box 2 is fixed with an upper expansion box 4, and a placement rack 5 is placed on the upper end of the lower supporting box 3. The placement rack 5 is used to place the plate to be processed. The upper end of the upper expansion box 4 is fixed with a liquid storage tank 6, and the liquid storage tank 6 is filled with an expansion liquid. The expansion liquid is selected from a liquid having a vaporization temperature and a heat dissipation temperature. The liquid with matching pressure temperature is supported, and a water pump is installed inside to transport the liquid to each part. The support side box 2 is connected to the liquid storage tank 6 through the return pipe 201. The return pipe 201 guides the cooled liquid inside the support side box 2 back to the liquid storage tank 6 to realize the recycling of the expansion liquid. The side wall of the lower support box 3 is fixed with a heat recovery box 7, and a central yielding mechanism is provided inside the lower support box 3. A waste heat utilization mechanism is provided inside the heat recovery box 7, and an expansion and extrusion mechanism is provided inside the upper expansion tank 4. The expansion and extrusion mechanism can use the pressure brought by the vaporization expansion to complete the hot pressing process, which ensures both pressure and temperature.

[0046] The expansion and extrusion mechanism includes a propulsion groove 401 provided at the bottom of the upper expansion tank 4, the inner wall of the propulsion groove 401 is sealed and slidably connected to a peripheral extrusion block 403, the peripheral extrusion block 403 and the inner bottom of the upper expansion tank 4 are jointly fixed with an expansion spring 402, a heating rod 404 is fixed to the inner wall of the upper expansion tank 4, and a liquid injection pipe 407 connected to the interior of the liquid storage tank 6 is fixed to the side wall of the upper expansion tank 4, the liquid injection pipe 407 is filled with expansion liquid into the interior of the upper expansion tank 4, and the heating rod 404 outputs heat after being energized, so that the temperature inside the upper expansion tank 4 rises rapidly. During the temperature rise, the expansion liquid absorbs heat, thereby changing itself from liquid to gas, and this process is accompanied by uniform heat diffusion and an increase in internal pressure;

[0047] Gas diffusion makes the heat distribution uniform, thereby making the heat utilization effect of the hot pressing process better, and the increase in internal pressure makes the peripheral extrusion block 403 begin to move downward gradually under the action of pressure, so that the peripheral extrusion block 403 can contact the plate to be processed, so that the plate to be processed can be effectively hot-pressed, and the hot pressing intensity is positively correlated with the heating temperature and the injection amount of the expansion fluid, and the control of pressure and temperature is consistent, so the overall control adjustment is very easy and reliable.

[0048] A plurality of spray pipes 405 connected to the liquid storage tank 6 are installed on the top of the upper expansion tank 4. The spray pipes 405 have built-in atomizing nozzles. The spray pipes 405 guide the expansion liquid inside the liquid storage tank 6 into the upper expansion tank 4, and use the built-in atomizing nozzle to realize the atomization and diffusion of the expansion liquid, so that the expansion liquid can be diffused in fine particles, and then the expansion liquid can absorb heat faster and more evenly, and then vaporize and expand, which is conducive to the rapid diffusion and rise of heat inside the upper expansion tank 4, and also enables the pressure inside the upper expansion tank 4 to be quickly increased, so as to improve the overall hot pressing efficiency. A pressure relief pipe 406 is installed on the side wall of the upper expansion tank 4. The pressure relief pipe 406 is used to discharge the vaporized high-temperature expansion liquid gas, so that the internal pressure of the upper expansion tank 4 is reduced, so that it can quickly recover and then enter the state for processing subsequent plates.

[0049] A peripheral heating chamber 40301 is defined at the lower portion of the peripheral extrusion block 403. A plurality of peripheral heating pipes 40302 are mounted at the upper end of the peripheral heating chamber 40301. The peripheral heating pipes 40302 are connected to the interior of the upper expansion tank 4. Expansion fluid enters the peripheral heating chamber 40301 through the peripheral heating pipes 40302. The peripheral heating pipes 40302 also transfer heat, thereby rapidly increasing the temperature within the peripheral heating chamber 40301 and effectively raising the bottom temperature of the peripheral extrusion block 403, thereby ensuring the desired temperature during the hot pressing process.

[0050] A central pressing groove 40303 is provided at the upper end of the peripheral extrusion block 403, and the inner wall of the central pressing groove 40303 is connected to the central pressing block 40306 through the central spring 40304. A limiting structure is provided at the upper end of the central pressing block 40306, which limits the movement of the central pressing block 40306, so that in the initial stage of hot pressing, the central pressing block 40306 and the peripheral extrusion block 403 maintain the same extrusion state, thereby completing the overall hot pressing in priority. A central heating cavity 40307 is provided inside the central pressing block 40306, and the central heating cavity 40307 is connected to the peripheral heating cavity 40301 through the central heating pipe 40308. The central heating pipe 40308 quickly transfers heat to the central heating cavity 40307, ​​thereby effectively improving the temperature of the central pressing block 40306, and thereby keeping the hot pressing temperature of the entire upper hot pressing surface consistent.

[0051] The limiting mechanism includes an intermediate pressure transmission block 40305 fixed to the upper end of the central pressure block 40306. A yield groove 40309 is provided at the upper end of the intermediate pressure transmission block 40305. The inner wall of the yield groove 40309 is connected to a yield block 40311 through a reset spring 40310. The yield block 40311 is sealed and slidably connected to the inner wall of the central pressure groove 40303. The interior of the yield groove 40309 is filled with oil. When the yield block 40311 is subjected to initial pressure, it will move downward, thereby squeezing the reset spring 40310, causing the reset spring 40310 to contract. The reset spring 40310 also serves to limit its downward movement, so that it will not move downward excessively when it is not subjected to specific pressure, thereby ensuring initial comprehensive hot pressing.

[0052] The inner wall of the central pressure groove 40303 is provided with a receiving groove 40312, and the inner wall of the receiving groove 40312 is connected to a clamping block 40314 via a clamping spring 40313. The side wall of the intermediate pressure transmission block 40305 is provided with a clamping groove 40315, and the clamping block 40314 partially slides into the clamping groove 40315, thereby limiting the movement of the intermediate pressure transmission block 40305. The inner wall of the clamping groove 40315 is connected to a push block 40317 via a connecting spring 40316. The side wall of the clamping groove 40315 is penetrated by a transfer hole 40318 connected to the yielding groove 40309. When 40311 is subjected to sufficiently strong pressure, the give way block 40311 will slide a sufficient distance in the give way groove 40309, so that there is enough oil in the give way groove 40309, which is pressurized to enter the positioning groove 40315 through the transfer hole 40318, so that the push block 40317 inside the positioning groove 40315 is pressed and moved, and then the positioning block 40314 is gradually pushed away from the positioning groove 40315, so that the positioning block 40314 will no longer hinder the movement of the intermediate pressure transmission block 40305, so that the central pressure block 40306 can be pressurized alone and apply pressure to the center position of the plate.

[0053] The center yielding mechanism includes a lower top block 302 which is sealed and slidably connected to the upper end of the lower support box 3. The lower top block 302 and the inner bottom of the lower support box 3 are fixed with a top pressure spring 301. The top pressure spring 301 supports the lower top block 302. The lower support box 3 and the lower top block 302 together form a comprehensive support for the lower area of ​​the plate. The bottom of the lower support box 3 is provided with a water hole 303 which is connected to the supporting bottom box 1. A solenoid valve is provided inside the water hole 303. The supporting bottom box 1 is connected to the water hole 303 through a built-in water pipe. When the block 40314 is out of the positioning groove 40315, the middle pressure transmission block 40305 moves downward, so that the block 403 14 is separated from the push block 40317, so that the electrical connection between the two is disconnected, thereby opening the internal valve of the water hole 303, allowing the water flow inside the lower support box 3 to enter the support bottom box 1, and then allowing the lower top block 302 to have space to move downward, thereby making room for the lower area of ​​the center of the plate, and allowing the plate to be squeezed by the central pressing block 40306, and bend downward from the center, realizing the extrusion treatment of the bending of the lower part of the plate, improving the strength of the plate, improving the pressing effect, and improving the uniformity of the internal structure of the composite plate after forming, ensuring better composite performance inside the composite plate, improving the toughness of the composite plate, and ensuring the performance after subsequent complex forming.

[0054] The waste heat utilization mechanism includes a regenerative heat pump 701 fixed inside the regenerative heat box 7. The water inlet of the regenerative heat pump 701 is connected to the pressure relief pipe 406. A heat exchange column 702 is installed through the side wall of the regenerative heat box 7, and the heat exchange column 702 extends into the lower support box 3. After the first hot pressing is completed, the pressure relief pipe 406 is opened, and the regenerative heat pump 701 guides the high-temperature airflow inside the upper expansion box 4 into the regenerative heat box 7, thereby increasing the temperature inside the regenerative heat box 7. Heat is transferred through the heat exchange column 702 to achieve heating treatment of the lower support box 3, so that the bottom of the plate is preheated to facilitate subsequent processing.

[0055] A transfer pump 703 is installed on the side wall of the lower support box 3. The water inlet and outlet of the transfer pump 703 are connected to the heat recovery box 7 and the support side box 2 respectively. The transfer pump 703 transfers the excess airflow and liquid to the support side box 2, where the excess airflow and liquid are cooled, liquefied and accumulated, and finally returned to the liquid storage tank 6, thereby realizing the recycling of the expansion liquid.

[0056] The heat exchange column 702 is a screw, and the outer wall of the heat exchange column 702 is threadedly connected to the heat exchange sleeve 70204. The outer wall of the heat exchange sleeve 70204 is fixed with a rotary blade 70205. The interior of the heat exchange column 702 is provided with a sliding groove 70202, and the side wall of the sliding groove 70202 is provided with an air-filling groove 70201. The interior of the sliding groove 70202 is sealed and slidably connected with a driving slider 70203. The driving slider 70203 is a magnet that can attract the heat exchange sleeve 70204 to move accordingly. The air-filling groove 70201 is connected to the interior of the heat recovery box 7. The high-temperature airflow entering the interior of the heat recovery box 7 will pass through the air-filling groove 70201 and then enter The sliding groove 70202 pushes the driving slider 70203 to move under the action of air pressure, and the driving slider 70203 will attract the heat exchange sleeve 70204 to move, and the helix angle of the thread on the outer wall of the heat exchange column 702 is large, and it has no self-locking ability, so that the heat exchange sleeve 70204 can be forced to move along the heat exchange column 702, and the existence of the thread makes the movement process of the heat exchange sleeve 70204 accompanied by rotation, thereby driving the rotating blade 70205 on it to rotate, and the rotation and stirring of the rotating blade 70205 makes the water flow inside the lower support box 3 stirred, thereby increasing the heat exchange efficiency and improving the preheating effect of the plate.
