Description

Technical Field

[0001] The present invention belongs to the technical field of composite material processing, and particularly relates to a device for curing and forming large composite material components with mobile vibration assistance. Background Art

[0002] At present, for large composite material components, especially single components with a length exceeding 10 meters, such as aircraft wings and wind turbine blades, higher requirements are imposed on the load-bearing capacity of the components, and a low-defect curing and forming process is required. Traditional low-defect curing and forming processes generally include autoclave processes, vibration-assisted forming processes, and double vacuum bag forming processes.

[0003] For traditional autoclave processes, such as the solution disclosed in the existing patent with the publication number CN113524721B, it is difficult to place such large composite material components, and it is only suitable for the forming of medium and small-sized composite material components. If the size of the autoclave is forcibly increased to meet the forming requirements, the energy consumption of the autoclave, the temperature and pressure inside the autoclave, and the construction cost will further increase as the component size increases.

[0004] Although both the vibration-assisted forming process and the double vacuum bag forming process can, to a certain extent, solve the problem of increased porosity of components in the absence of the curing pressure provided by an autoclave, for large composite material components, these two existing processes, like the autoclave process, have size limitation problems. The design, control, and construction difficulty of large vibration tables increase sharply with the increase in size. For the double vacuum bag process, the required vacuum chamber suitable for large composite material components is not only difficult to construct, but also the vacuum uniformity and forming efficiency are major problems, because the process equipment of related processes needs to change with the component size and cannot be adjusted flexibly.

[0005] In the prior art, a segmented curing process is also adopted to cure large-sized composite materials, such as the solution disclosed in the existing patent with the publication number CN117584488B. However, this method of achieving segmented curing of composite materials by setting up multiple conveyor belt assemblies is only suitable for curing thin composite material coatings or sheets, and is not suitable for the curing and forming of large composite material components such as aircraft wings and wind turbine blades. Also, due to the absence of a vibration energy field, the curing and forming quality is not high.

[0006] In view of the above defects of the prior art, it is necessary to develop a low-porosity curing and forming device that is not restricted by the size of composite material components to solve the size restriction and porosity control problems brought about by the large-scale and single-piece development of composite material components.

Detailed Embodiment

[0034] To more conveniently understand the technical solution of this invention application, the following further describes the technical solution of this invention application in conjunction with the drawings and specific embodiments.

[0035] Embodiment 1:

[0036] A device for curing and forming large composite components with mobile vibration assistance provided by the present invention includes a bottom mold 1, a top mold, a vibration mechanism, a first driving member, a second driving member, a flexible seal 4, and a vacuum generator.

[0037] Please refer to Figures 1-2 , a first heating member (not shown in the figure) is built into the bottom mold 1. The first heating member is a combination of multiple electric heating wires. A composite material preform 5 is laid on the surface of the top of the bottom mold 1, and the first heating member provides heat for the bottom curing and forming of the composite material preform 5.

[0038] The top mold further includes several templates 2. The several templates 2 are arranged side by side along the length direction of the composite material preform 5. A connection hole 23 is provided at the top of the template 2. The bottom surface of the template 2 fits with the composite material preform 5. Release agents are applied to the fitting surfaces of the composite material preform 5 with the template 2 and the bottom mold 1 to facilitate demolding and prevent sticking to the mold.

[0039] Please refer to Figure 3 , dovetail tenons 21 and dovetail grooves 22 are respectively provided on two opposite side walls of the template 2 along the length direction of the composite material preform 5. Adjacent templates 2 are spliced through the dovetail tenons 21 and dovetail grooves 22. There is a gap at the splicing part, and the width direction of this gap is consistent with the vibration direction of the vibration mechanism, so that adjacent templates 2 can move relative to each other under the action of the vibration mechanism, and grease is injected into the gap to reduce the wear of the template 2. A second heating member (not shown in the figure) is built into the template 2. The second heating member is a combination of multiple electric heating wires, and the second heating member provides heat for the top curing and forming of the composite material preform 5.

[0040] Please refer to Figure 1 , Figure 4 and Figure 5 , the vibration mechanism is arranged above the top mold formed by splicing several templates 2. The vibration mechanism includes a vibration frame platform 3. C-shaped guide rails 11 are provided on both sides of the bottom mold 1 along the length direction of the composite material preform 5. Guide wheels 31 are provided on the vibration frame platform 3. The guide wheels 31 are provided with guide grooves, and the guide grooves can cooperate with the guide rails, so that the guide wheels 31 roll on the top surface of the C-shaped guide rails 11.

[0041] The first driving member (not shown in the figure) is connected to the vibration frame platform 3. The first driving member is a driving motor, which is arranged on the vibration frame platform 3. The output rotating shaft of the driving motor is in transmission connection with the guide wheel 31. The driving motor can drive the vibration frame platform 3 to move on the guide rail, so as to realize the movement of the vibration mechanism relative to the composite material preform 5, and the moving direction is the length direction of the composite material preform 5.

[0042] Please refer to Figures 4-6 , the second driving member (not shown in the figure) is an electric lifting cylinder. The cylinder body of the electric lifting cylinder is arranged on the vibration frame platform 3, and the piston rod of the electric lifting cylinder is connected to the guide wheel 31. The vibration mechanism further includes an exciter 32 arranged on the vibration frame platform 3. In this embodiment, a total of five exciters 32 are provided. Connecting columns 33 are provided at the bottoms of the five exciters 32. The connecting columns 33 are arranged to pass downward through the vibration frame platform 3, and the connecting columns 33 are matched with the connecting holes 23. The vibration frame platform 3 covers two adjacent templates 2. Two complete connecting holes 23 are arranged on each template, and a connecting hole 23 is arranged at the splicing position between two adjacent templates. The five connecting columns 33 and the total five connecting holes 23 on two adjacent templates are arranged in a plum blossom shape, so that two adjacent templates 2 can vibrate together, and the vibration energy fields are as consistent as possible. The electric lifting cylinder can drive the vibration mechanism to rise or fall, so that the connecting column 33 of the exciter 32 is inserted into the connecting hole 23 of the template 2, or the connecting column 33 of the exciter 32 is disengaged from the connecting hole 23 of the template 2. The vibration energy field generated by the exciter 32 is transmitted to the template 2 through the connecting column 33, and then to the composite material preform 5.

[0043] A limiting strip 34 is arranged on the side of the vibration frame platform 3. After the electric lifting cylinder drives the vibration mechanism to descend, the limiting strip 34 fits with the U-shaped guide rail 11 and is locked and fixed by a U-shaped limiting member 35. Thus, the vibration frame platform 3 is positioned and fixed on the guide rail to prevent the vibration frame platform 3 from disengaging from the guide rail during operation. When the electric lifting cylinder needs to drive the vibration mechanism to rise, the U-shaped limiting member 35 is loosened and removed, and the guide rail and the vibration frame platform 3 can be disengaged. The locking and fixing of the U-shaped limiting member 35 is carried out by an external manipulator first clamping the U-shaped limiting member 35 on the limiting strip 34 and the U-shaped guide rail 11, and then tightening the bolts on the U-shaped limiting member 35 by the manipulator. The removal of the U-shaped limiting member 35 is also carried out by the reverse operation of the manipulator. Of course, the operation of locking and fixing or removing the U-shaped limiting member 35 can also be directly completed manually.

[0044] The flexible seal 4 is an airbag, which is adhesively bonded around the bottom of the vibration frame platform 3. And an air charging and discharging device (not shown in the figure) communicating with the airbag is arranged on the vibration frame platform 3. When the electric lifting cylinder drives the vibration mechanism to descend, after the U-shaped limiting member 35 locks and fixes the limiting strip 34 and the U-shaped guide rail 11, the airbag is inflated and is in sealed contact with the template 2 and the bottom die 1 to enclose and form a sealed cavity. Among them, the flexible seal 4 is in close contact with the top surface of the template 2 at the front and rear ends in the length direction of the composite material preform 5, and is in close contact with the top surface of the bottom die 1 on the left and right sides in the length direction of the composite material preform 5. A vacuum generator (not shown in the figure) is arranged on the vibration mechanism and is communicated with the sealed cavity. The vacuum generator starts to work to evacuate the sealed cavity.

[0045] A sealing plate 36 is arranged at the top of the sealed cavity. The sealing plate 36 is arranged at an interval from the top plate of the vibration frame platform 3. The sealing plate 36 is adhesively bonded to the inner side walls around the vibration frame platform 3 through a sealant. The connecting column 33 passes through the sealing plate 36, and the connecting column 33 is also adhesively bonded to the sealing plate 36 through a sealant. By arranging the sealing plate 36, on the one hand, the volume of the sealed cavity is reduced, the time for evacuating the vacuum is shortened, and the vacuum evacuation efficiency is improved. On the other hand, the sealing plate 36 is adhesively bonded to the vibration frame platform 3 and the connecting column 33 through a sealant to form a flexible connection structure. In addition, the airbag is also a flexible structure, so that the whole sealed cavity is a flexible sealing structure. Under the influence of the cyclic load generated by the vibration energy field, the sealed cavity is not easy to leak and affect the vacuum degree.

[0046] During operation, first place the composite material preform 5 on the surface of the top of the bottom die 1, then place the spliced top die on the composite material preform 5, and place the guide wheels 31 of the vibration mechanism on the U-shaped guide rail 11 so that the vibration mechanism can slide on the U-shaped guide rail 11. Control the driving motor to drive the vibration frame platform 3 to move to the starting position of work, and then control the electric lifting cylinder to drive the vibration mechanism to descend so that the connecting columns 33 of the five exciters 32 are inserted into the connecting holes 23 of the corresponding two templates 2. At the same time, the limiting strip 34 is in contact with the U-shaped guide rail 11. Then use a manipulator to clamp the U-shaped limiting member 35 on the limiting strip 34 and the U-shaped guide rail 11 and lock it with bolts. The air charging and discharging device inflates the airbag so that the airbag is in sealed contact with the template 2 and the bottom die 1 to enclose and form a sealed cavity, and the sealed cavity seals and covers the part of the composite material preform 5 at the starting position. Then start the electric heating wires at the corresponding positions in the bottom die 1 and the vibration frame platform 3, start the electric heating wires in the two templates 2 corresponding to the vibration frame platform 3, start the vacuum generator to evacuate the sealed cavity, and start the exciters 32 to generate a vibration energy field to start curing and forming the composite material preform 5 at the starting position.

[0047] After the composite material preform 5 at the starting position is cured and formed, the electric heating wire corresponding to the starting position stops heating, the vibrator 32 stops working, the vacuum generator stops evacuating, the air charging and discharging device evacuates the airbag, contracts the airbag, the manipulator removes the C-shaped limiting member 35, and the electric lifting cylinder drives the vibration mechanism to rise, so that the connecting columns 33 of the five vibrators 32 are disengaged from the connecting holes 23 of the corresponding two templates 2. The driving motor drives the vibration frame platform 3 to move to the next curing and forming position, and the electric lifting cylinder drives the vibration mechanism to descend again, so that the connecting columns 33 of the five vibrators 32 are inserted into the connecting holes 23 of the corresponding two templates 2, the manipulator locks the C-shaped limiting member 35, starts the vacuum generator, the vibrator 32 and the corresponding electric heating wire, and starts the curing and forming at the next position. And so on until the curing and forming of the entire composite material preform 5 is completed.

[0048] It should be noted that the driving motor drives the vibration frame platform 3 to move to the starting position, and the positions that need to be moved for each curing and forming can be realized by setting a distance sensor on the bottom mold 1, setting an induction member on the vibration frame platform 3 that cooperates with the distance sensor through signal induction, and connecting the distance sensor to the control end of the driving motor through signals. Its specific control principle belongs to the existing relatively conventional technology and will not be elaborated here. Of course, the distance of each movement can also be controlled by the program built into the driving motor, and only the vibration frame platform 3 needs to be manually positioned for the first time. This control principle also belongs to the existing technology and will not be elaborated here. In addition, the actions of the driving motor, the electric lifting cylinder, the vibrator 32, the air charging and discharging device, the electric heating wire and the vacuum generator can be controlled by the existing control technology or manually.

[0049] Embodiment 2:

[0050] Different from Embodiment 1, both the first heating member and the second heating member adopt steam heating pipes, the dovetail tenons 21 and the dovetail grooves 22 are respectively replaced by T-shaped blocks and T-shaped grooves, and the second driving member adopts an electric lifting screw.

[0051] Embodiment 3:

[0052] Different from Embodiment 1, both the first heating member and the second heating member adopt electric heating rods, and the first driving member adopts a tractor in the existing technology. The tractor is arranged on the guide rail and is connected to the vibration frame platform 3.

[0053] Embodiment 4:

[0054] Different from Embodiment 1, both the first heating element and the second heating element adopt heating oil pipes, and the temperature is easier to control. The flexible seal 4 adopts a rubber ring, which is bonded to the periphery of the bottom of the vibration frame platform 3. The sealing structure of the rubber ring is simpler than that of the airbag and is easier to manufacture, but it is necessary to ensure that the rubber ring has the flexibility to seal the composite preform 5.

[0055] Embodiment 5:

[0056] Please refer to Figure 7 , different from Embodiment 1, the U-shaped limiting member 35 is replaced by a limiting clip 37. The limiting clip 37 is hinged to the limiting strip 34, and a torsion spring (not shown in the figure) is provided at the hinge. One end of the torsion spring is connected to the limiting clip 37, and the other end is connected to the limiting strip 34. A third driving member 38 is provided on the vibration frame platform 3. The third driving member 38 is an electric lifting screw, and the electric lifting screw is located above the first end of the limiting clip 37. Under normal conditions, the electric lifting screw descends to abut against the first end of the limiting clip 37 and makes the limiting clip 37 in an open state. When it is necessary to fix the vibration frame platform 3 on the guide rail, only need to raise the electric lifting screw to disengage from the limiting clip 37. Under the restoring force of the torsion spring, the second end of the limiting clip 37 rotates to be caught in the U-shaped guide rail 11, and under the action of the torsion spring force, it keeps the limiting strip 34 and the guide rail locked and fixed. It should be noted that the so-called locking and fixing here allows there to be a gap between the limiting clip 37, the limiting strip 34 and the guide rail, so as to ensure that the second end of the limiting clip 37 can smoothly rotate to be caught in the U-shaped guide rail 11 during the automatic locking process, and only need to ensure that the limiting strip 34 and the guide rail will not completely disengage. Since the vibration frame platform 3 also vibrates under the action of the vibrator 32, this structure needs to ensure that the elastic force of the torsion spring can still make the limiting clip 37 lock and fix the limiting strip 34 and the guide rail in this vibration environment.

[0057] Embodiment 6:

[0058] Please refer to Figure 8 , the guide wheels 31 on the vibration frame platform 3 roll in the grooves on the side of the U-shaped guide rail 11. When the vibration frame platform 3 is affected by the vibration of the vibrator 32, the rolling of the guide wheels 31 can be restricted by the friction force of the airbag, and then the movement of the vibration frame platform 3 during operation can be restricted, so that the vibration frame platform 3 is kept at the curing and forming position, and thus the limiting member can be omitted and the structure is simpler.

[0059] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions and substitutions can still be made, and all should be regarded as belonging to the protection scope of the present invention.
