Description

Technical Field

[0001] The invention belongs to the technical field of composite material processing, and in particular relates to a mobile vibration-assisted device for curing and molding large composite material components. Background Art

[0002] At present, large composite components, especially single components with a length of more than 10 meters, such as aircraft wings and wind turbine blades, have high requirements on the bearing capacity of the components and need to adopt low-defect curing molding processes. Traditional low-defect curing molding processes generally include autoclave process, vibration-assisted molding process and double vacuum bag molding process.

[0003] Traditional autoclave technology, such as the solution disclosed in the existing patent with announcement number CN113524721B, is difficult to accommodate such large composite components and is only suitable for the molding of small and medium-sized composite components. If the size of the autoclave is forcibly increased to meet the molding needs, the energy consumption of the autoclave, the temperature and pressure inside the autoclave, and the construction cost will also increase further with the increase in the size of the component.

[0004] Although the vibration-assisted molding process and the double vacuum bag molding process can solve the problem of increased component porosity in the absence of curing pressure provided by an autoclave to a certain extent, for large composite components, these two existing processes have the same size limitation problem as the autoclave process. The difficulty of designing, controlling and constructing a large vibration table increases sharply with the increase in size. The vacuum cavity required by the double vacuum bag process, which is suitable for large composite components, is not only difficult to build, but also has major problems with vacuum uniformity and molding efficiency, because the process equipment of the relevant processes needs to change with the changes in component size and cannot be flexibly adjusted.

[0005] The prior art also uses a segmented curing process to cure large-sized composite materials, such as the solution disclosed in the existing patent with announcement number CN117584488B. However, this method of achieving segmented curing of composite materials by setting up multiple conveyor belt assemblies is only suitable for the curing of thinner composite coatings or sheets, and is not suitable for the curing and molding of large composite components such as aircraft wings and wind turbine blades. Also, because there is no vibration energy field, the curing and molding quality is not high.

[0006] In view of the above defects of the existing technology, it is also necessary to develop a low-porosity curing and molding device that is not restricted by the size of composite components, so as to solve the size constraints and pore control problems brought about by the large-scale and monomerized development of composite components.

DETAILED DESCRIPTION

[0027] To facilitate understanding of the technical solution of the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0028] Embodiment 1: The present invention provides a mobile vibration-assisted large composite material component curing and molding device, comprising a bottom mold 1, a top mold, a vibration mechanism, a first driving member, a second driving member, a flexible sealing member 4 and a vacuum generator.

[0029] See also Figure 1-Figure 2 The bottom mold 1 has a built-in first heating element (not shown in the figure), which is a combination of multiple electric heating wires. The top surface of the bottom mold 1 is laid with a composite material preform 5, and the first heating element provides heat for the bottom curing molding of the composite material preform 5.

[0030] The top mold includes a plurality of templates 2, which are arranged side by side along the length direction of the composite material preform 5. A connecting hole 23 is provided on the top of the template 2. The bottom profile of the template 2 fits with the composite material preform 5. The fitting surfaces of the composite material preform 5, the template 2 and the bottom mold 1 are coated with a release agent to facilitate demoulding and prevent mold sticking.

[0031] See also Figure 3 The template 2 is provided with dovetail tenons 21 and dovetail grooves 22 on two opposite side walls along the length direction of the composite material preform 5, and two adjacent templates 2 are spliced ​​by dovetail tenons 21 and dovetail grooves 22. There is a gap at the splicing, and the width direction of the gap is consistent with the vibration direction of the vibration mechanism, so that the two 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. The template 2 is built with a second heating element (not shown in the figure), which is a combination of multiple electric heating wires, and the second heating element provides heat for the top curing molding of the composite material preform 5.

[0032] See also Figure 1 , Figure 4 and Figure 5 The vibration mechanism is arranged above the top mold which is spliced ​​by several templates 2. The vibration mechanism includes a vibration frame platform 3. The bottom mold 1 is provided with U-shaped guide rails 11 on both sides along the length direction of the composite material preform 5. The vibration frame platform 3 is provided with a guide wheel 31. The guide wheel 31 is provided with a guide groove. The guide groove can cooperate with the guide rail so that the guide wheel 31 rolls on the top surface of the U-shaped guide rail 11.

[0033] 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.

[0034] Please refer to Figure 4-Figure 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 arranged. 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 every two adjacent templates. The five connecting columns 33 and the total five connecting holes 23 on every two adjacent templates are arranged in a plum blossom shape, so that the 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 separated 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 transmitted to the composite material preform 5.

[0035] A limiting strip 34 is arranged on the side surface of the vibration frame platform 3. After the electric lifting cylinder drives the vibration mechanism to descend, the limiting strip 34 is attached to 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 detaching 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 released. The locking and fixing of the U-shaped limiting member 35 is achieved by first clamping the U-shaped limiting member 35 on the limiting strip 34 and the U-shaped guide rail 11 by an external manipulator, and then locking 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.

[0036] 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 provided 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 makes sealing 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 provided on the vibration mechanism and communicates with the sealed cavity. The vacuum generator starts to work to evacuate the sealed cavity.

[0037] A sealing plate 36 is provided at the top of the sealed cavity. The sealing plate 36 is spaced 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 with 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 with sealant. By providing the sealing plate 36, on the one hand, the volume of the sealed cavity is reduced, the time for evacuating the air is shortened, and the 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 with sealant, forming a flexible connection structure. In addition, the airbag is also a flexible structure, making the whole sealed cavity 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.

[0038] During operation, first place the composite material preform 5 on the surface of the top of the bottom die 1, then place the assembled 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 makes sealing 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 of 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.

[0039] After the composite material preform 5 located 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 U-shaped limiting member 35, 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 U-shaped limiting member 35, starts the vacuum generator, the vibrator 32 and the corresponding electric heating wire, and starts the curing and forming of the next position. This process is repeated until the curing and forming of the entire composite material preform 5 is completed.

[0040] 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 die 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 a signal. 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 in 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.

[0041] Embodiment 2: 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.

[0042] Embodiment 3: 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 prior art. The tractor is arranged on the guide rail and is connected to the vibration frame platform 3.

[0043] Embodiment 4: Different from Embodiment 1, both the first heating member and the second heating member adopt heating oil pipes, the temperature is easier to control, the flexible seal 4 adopts a rubber ring, the rubber ring is bonded to the periphery of the bottom of the vibration frame platform 3, and the sealing structure of the rubber ring is simpler than that of the airbag and is easy to manufacture, but it is necessary to ensure that the rubber ring has the flexibility to seal the composite material preform 5.

[0044] Example 5: Please refer to Figure 7 , different from Example 1, the U-shaped limiting member 35 is replaced by a limiting clip 37. The limiting clip 37 is hinged on 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 clamped into the U-shaped guide rail 11, and under the action of the torsion spring force, the limiting strip 34 and the guide rail are 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 clamped into 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.

[0045] Example 6: Please refer to Figure 8 , the guide wheel 31 on the vibration frame platform 3 rolls in the groove on the side of the U-shaped guide rail 11. When the vibration frame platform 3 is under the vibration action of the vibrator 32, the rolling of the guide wheel 31 can be restricted by the friction force of the airbag, and further 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, thus eliminating the need for a limiting member and making the structure simpler.

[0046] 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, which should all be regarded as belonging to the protection scope of the present invention.
