Description

Technical Field

[0001] This utility model relates to the field of high-temperature curing technology, specifically a high-temperature resin curing device for manufacturing carbon fiber wheel hubs. Background Technology

[0002] Carbon fiber wheels are widely used in high-end automobiles, aerospace, and sporting goods due to their excellent properties such as lightweight, high strength, and fatigue resistance. In the manufacturing process of carbon fiber wheels, carbon fibers typically exist in a loose structure of filaments or cloth. They need to be impregnated with a resin matrix and then cured at high temperatures to bond the carbon fibers and resin into a dense, integral structure. The high-temperature resin curing process is a crucial step that determines the final performance of the wheel; its quality directly affects the product's mechanical strength, dimensional stability, and service life.

[0003] Currently, existing methods for high-temperature curing of carbon fiber wheel hub resin include hot air heating, mold-in-mold electric heating, and fluid heating. Among these, hot air heating utilizes hot air flowing evenly through the mold and the surface of the carbon fiber wheel hub inside, transferring heat through convection heat transfer.

[0004] Existing hot air heating methods typically involve direct high-temperature curing at a predetermined temperature, which can cause the resin viscosity to drop too quickly and make it difficult to control the crosslinking reaction rate. This can easily lead to localized overheating or uneven reaction, resulting in internal stress concentration, microcracks, and ultimately reduced product quality.

[0005] Therefore, this invention provides a high-temperature resin curing device for manufacturing carbon fiber wheel hubs to solve the above-mentioned problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the existing high-temperature curing of carbon fiber wheel hub resin uses hot air to directly cure at a predetermined temperature, which can easily lead to local overheating or uneven reaction, thereby easily reducing product quality.

[0007] This utility model provides the following technical solution: a high-temperature resin curing device for manufacturing carbon fiber wheel hubs, comprising a frame, a partition, and a heating assembly.

[0023] Addressing the issue that existing high-temperature curing methods for carbon fiber wheel hub resins, which use hot air for direct curing at a predetermined temperature, can easily lead to localized overheating or uneven reaction, thus reducing product quality, the following solutions are proposed: Figures 1 to 3 As shown in the figure, this disclosure provides a high-temperature resin curing device for manufacturing carbon fiber wheel hubs, including a frame 1, a partition 2, and a heating assembly. The frame 1 is provided with a heating and curing chamber 3. The partition 2 is slidably installed in the heating and curing chamber 3, and the partition 2 divides the heating and curing chamber 3 into a left preheating chamber 31 and a right heat curing chamber 32. The heating assembly includes a preheating component 4, a heating component 5, a connecting component 6, and a supplementary heating component 7. The preheating component 4 is installed in the left preheating chamber 31, and the heating component 5 is installed in the right heat curing chamber 32. The connecting component 6 is fixedly installed between the left preheating chamber 31 and the heating component 5, and the supplementary heating component 7 is installed in the connecting component 6.

[0024] In the manufacturing process of carbon fiber wheels, since carbon fiber has a loose structure in the form of filaments or cloth, it needs to be bonded together into a whole by passing it through a resin matrix and undergoing high-temperature curing.

[0025] During the high-temperature curing process, the mold is first fed into the left preheating chamber 31 of the heating and curing chamber 3 through the openings on both sides using any available method, such as manual pushing or using an existing robotic arm, hydraulic or pneumatic telescopic rod to transport the mold. After the mold enters the left preheating chamber 31, the preheating component 4 is activated to initially heat the mold, thereby preheating the mold and the carbon fiber hub inside. This initial preheating significantly reduces the resin viscosity, making it easier for the resin to fill the tiny gaps and fully impregnate the carbon fiber bundles, and also facilitating the complete removal of air from the resin to avoid air bubble residue.

[0026] It should be noted that the heating and curing chamber 3 has sealing openings on both horizontal sides, allowing the mold to enter and exit from both sides.

[0027] like Figure 2 and 3As shown, after initial preheating in the left preheating chamber 31, the mold in the partition 2 is opened and enters the right thermosetting chamber 32, and the heating element 5 is activated. The heating element 5 further heats the mold, thereby slowly activating the curing agent and initiating the cross-linking reaction. This allows for gradual shrinkage of the cured resin volume through a stepped heating process, which helps to release stress and improve product quality.

[0028] It should be noted that during the start-up process of the heating element 5, the connecting piece 6 can be opened to transport the hot air in the preheating chamber to the heating element 5, thereby reducing the temperature of the hot air output by the heating element 5. This is beneficial for controlling the heating temperature and improving the flexibility of use.

[0029] Furthermore, after the heating element 5 is activated to slowly heat up and activate the curing agent to initiate the cross-linking reaction, the supplementary heating element 7 is activated, which can further increase the temperature, thereby accelerating the cross-linking reaction and ensuring complete curing.

[0030] It should also be noted that, since the confluence of different hot air streams will cause the temperature to fall between the two, the hot air temperature output by the heating element 5 is greater than that of the preheating element 4, and the hot air temperature output by the supplementary heating element 7 is greater than that of the heating element 5.

[0031] It should also be noted that the mold can enter the left preheating chamber 31 or enter the right heating chamber from the left preheating chamber 31 using any existing conveying method, such as manual conveying, or by fixing a high-temperature resistant pneumatic or hydraulically driven telescopic rod in the left preheating chamber 31, which completes the feeding process with one extension after the partition 2 is opened. Given that the conveying mold uses an existing feeding method, further details will not be elaborated here.

[0032] like Figure 2 and 3 As shown, the partition 2 includes a telescopic component 21 and a partition 22. The telescopic component 21 is fixedly installed on the top of the frame 1, and the partition 22 is fixedly installed on the lower end of the telescopic component 21.

[0033] After the mold and its internal carbon fiber hub have completed initial preheating in the left preheating chamber 31, the telescopic component 21 is activated to retract, thereby allowing the partition 22 to move down to facilitate the transfer of the mold and its carbon fiber hub to the right heating chamber.

[0034] It should be noted that the telescopic member 21 can adopt any existing telescopic structure, such as existing pneumatic, hydraulic or electric push rods.

[0035] like Figure 2 and 3As shown, the preheating component 4 includes a first hot air blower 41 and a first inlet pipe 42. One end of the first inlet pipe 42 is fixedly installed above the left preheating chamber 31, and the first hot air blower 41 is fixedly installed above the frame 1. The other end of the first inlet pipe 42 is fixedly connected to the first hot air blower 41.

[0036] When the left preheating chamber is initially heated, the first hot air blower 41 is started to deliver heated air from the outside along the first inlet pipe 42 into the left preheating chamber, thereby initially heating the mold and the carbon fiber hub inside.

[0037] like Figure 2 and 3 As shown, the heating element 5 includes a second hot air blower 51 and a second inlet pipe 52. One end of the second inlet pipe 52 is fixedly installed at the bottom of the right thermosetting chamber 32. The second hot air blower 51 is fixedly installed at the bottom of the frame 1. The other end of the second inlet pipe 52 is fixedly connected to the second hot air blower 51.

[0038] After the mold and the carbon fiber wheel hub inside it enter the right heating chamber, the second hot air blower 51 is started, thereby delivering heated air from the outside along the second inlet pipe 52 to the left preheating chamber, thus preheating the mold and the carbon fiber wheel hub inside it.

[0039] like Figure 2 and 3 As shown, the connector 6 includes a connecting pipe 61 and a control solenoid valve 62 for temperature compensation. One end of the connecting pipe 61 is fixedly installed at the bottom of the left preheating chamber 31, and the other end of the connecting pipe 61 is fixedly connected to the second inlet pipe 52. The solenoid valve is fixedly installed inside the connecting pipe 61.

[0040] When the mold and its internal carbon fiber hub enter the right heating chamber and the second hot air blower 51 is activated, the control temperature compensation solenoid valve 62 is opened. This allows hot air from the left preheating chamber to enter the second inlet pipe 52, lowering the temperature in the right heating chamber. This slowly heats the mold and its internal carbon fiber hub, facilitating temperature control and improving operational flexibility. After the heating and curing process in this stage has lasted for a certain time or reached the predetermined temperature, the control temperature compensation solenoid valve 62 is closed, allowing the temperature of the heated component 5 to rise again. This then reheats the mold and its internal carbon fiber hub, achieving staged heating to improve product quality.

[0041] It should also be noted that the two ends of the connecting pipe 61 do not overlap with the mold, and the two ends of the connecting pipe 61 can be located at any position around the mold. For example, they can be in a rectangular structure located on both sides of the mold and close to both sides of the width of the heating and curing chamber 3, or they can be in a ring or "U" shaped structure surrounding the mold.

[0042] It should be noted that a recovery pipe for recovering hot air from the left preheating chamber 31 is also fixedly installed inside the connecting pipe 61. Furthermore, a recovery solenoid valve is fixedly installed inside the recovery pipe. When the control temperature compensation solenoid valve 62 is closed, the recovery solenoid valve is opened, thereby allowing the hot air from the left preheating chamber 31 to enter the recovery pipe, thus enabling the recovery and reuse of hot air to form a hot air circulation.

[0043] like Figure 2 and 3 As shown, the heat-generating component 7 includes a third hot air blower 71 and a third inlet pipe 72. The third hot air blower 71 is fixedly installed at the bottom of the frame 1. One end of the third inlet pipe 72 is fixedly installed on the surface of the third hot air blower 71, and the other end of the third inlet pipe 72 is fixedly connected to the interior of the connecting pipe 61.

[0044] After the control heating solenoid valve 62 is closed and the heating element 5 heats the mold independently, the third hot air blower 71 is started, thereby delivering the heated air from the outside, which is higher than that of the heating element 5, to the connecting pipe 61 along the third inlet pipe 72, thereby further increasing the temperature of the air output by the heating element 5, thereby accelerating the cross-linking reaction and ensuring complete curing.

[0045] like Figure 2 and 3 As shown, a perforated guide plate 8 is fixedly installed at the end of the first inlet pipe 42 and / or the second inlet pipe 52.

[0046] When hot air flows out of the first inlet pipe 42 and the second inlet pipe 52, the hot air passes through the porous guide plate 8, which disperses the eddies in the airflow and makes the hot air flow smoothly and laminarly, which is conducive to uniform heating and curing and improves product quality.

[0047] It should be noted that the porous guide plate 8 can be an existing porous structure guide plate.

[0048] In the process of manufacturing carbon fiber wheels, firstly, personnel use any available means to send the mold into the left preheating chamber 31 of the heating and curing chamber 3. Then, the first hot air blower 41 is started to transport heated air from the outside along the first inlet pipe 42 into the left preheating chamber, thereby preheating the mold and the carbon fiber wheel inside. This preheating significantly reduces the viscosity of the resin, which is more conducive to filling the tiny gaps in the resin and fully wetting the gaps in the carbon fiber bundles, and also more conducive to completely expelling air from the resin to avoid air bubbles.

[0049] Then, after the preheating is completed, the telescopic component 21 is activated to retract, thereby allowing the partition 22 to move down to facilitate the delivery of the mold and its carbon fiber hub to the right heating chamber. Then, the telescopic component 21 extends and drives the partition 22 to block the left preheating chamber 31 and the right thermosetting chamber 32.

[0050] After the mold and its carbon fiber hub enter the right heating chamber, the second hot air blower 51 is started and the control temperature compensation solenoid valve 62 is opened, so that the hot air in the left preheating chamber enters the second inlet pipe 52 and reduces the temperature in the right heating chamber, thereby slowly heating the mold and its internal carbon fiber hub. This helps to control the heating temperature and improve the flexibility of use.

[0051] In the subsequent heating and curing process, the control and temperature compensation solenoid valve 62 is closed, thereby restoring the temperature of the heating element 5 to a higher level, which in turn heats the mold and its internal carbon fiber hub again, thus achieving staged heating which is beneficial to improving product quality.

[0052] In the subsequent heating and curing process, the third hot air blower 71 is started, thereby transporting the heated air from the outside, which is higher than that of the heating element 5, to the connecting pipe 61 along the third inlet pipe 72, thereby further increasing the temperature of the air output by the heating element 5, thus accelerating the cross-linking reaction and ensuring complete curing.

[0053] In this embodiment, the step-by-step heating and curing process optimizes resin wetting and bubble removal, eliminates internal defects, and precisely controls the resin crosslinking reaction, avoiding local overheating and uneven curing, thereby improving product quality.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
