Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of demoulding of aviation composite stiffened panels, and particularly relates to an auxiliary device for demoulding an airbag of a stiffened panel. Background Technique
[0002] The demoulding of the airbag of the stiffened panel is a process used in the manufacture of composite structures or stiffened panels. It uses an airbag as part of the mould to form the internal shape of the panel. The inner cavity of the stringer of the stiffened panel needs to use an airbag for assistance during forming. After forming, the airbag is closely attached to the inner cavity of the stringer due to the tank pressure. Because the length of the stringer is too long and has a certain curvature, it is very difficult to demould, and it is easy to have residual debris in the inner cavity of the stringer. During the manufacturing process of parts, the demoulding of the airbag becomes a crucial step. When demoulding, its efficiency is low, the demoulding time is too long, and there is a risk that the airbag cannot be completely taken out. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an auxiliary device for demoulding an airbag of a stiffened panel, which solves the problems of low efficiency, too long demoulding time and the risk that the airbag cannot be completely taken out during demoulding.

[0011] (3) Beneficial effects
[0012] 1. When using, first insert the two metal blocks into the inner cavity of the airbag to be demolded, ensuring that the metal blocks are tightly fitted to the airbag. Then use the vacuum pipeline to connect the connecting pipe set in the left metal block to vacuum the airbag until it is completely deflated. By vacuuming the airbag, it is separated from the inner cavity of the long stringer. After the airbag is completely separated from the long stringer, it will be very easy to pull the airbag out, and there will be no residue in the inner cavity. The overall structure improves the efficiency of airbag demolding through auxiliary tools, reduces the risk of residue in the inner cavity, and ensures the quality of the part.
[0013] 2. Two sets of air cushions are set on the surfaces of the two metal blocks to ensure the tightness during connection and increase the friction of the connection. When the connection is completed, pull the handle block upward to drive the fixed block fixed with it to move together, compress the spring, and then move the connecting block to the connection between the airbag and the metal block. The elastic force of the spring drives the fixed block to reset. The fixed block is clamped with the upper surface of the airbag through a set of limit blocks fixed below it. This structure further ensures the stability of the connection between the metal block and the airbag, so that the metal block will not move easily, thereby improving the overall demoulding efficiency.

When in use, first, two metal blocks 2 are inserted into the inner cavity of the airbag 1 to be demoulded, and it is necessary to ensure that the metal blocks 2 are tightly fitted with the airbag 1. Then, the vacuum pipeline 6 is connected to the connecting pipe 3 arranged in the left metal block 2 to evacuate the airbag 1 until the airbag 1 is completely deflated. By evacuating the airbag 1, it is separated from the inner cavity of the stringer. After the airbag 1 is completely separated from the stringer, it is very easy to pull out the airbag 1 at this time, and there will be no residues in the inner cavity.

[0021] Embodiment
[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the technical solution in the embodiment of the present application effectively solves the problems of low efficiency, too long demoulding time and the risk that the airbag cannot be completely taken out during demoulding. The general idea is as follows:
[0023] In view of the problems existing in the prior art, the utility model provides an auxiliary device for demolding a reinforced panel airbag, which includes an airbag 1. Metal blocks 2 are movably clamped on both the left and right sides of the airbag 1. Connection blocks 8 are arranged on the upper surfaces of the two metal blocks 2. Second chucks 12 are opened on the lower surfaces of the two connection blocks 8. Fixing blocks 15 are movably clamped in the two second chucks 12. Handle blocks 9 are fixedly connected to the surfaces of the two fixing blocks 15. A connecting pipe 3 is fixedly connected to the metal block 2 on the left side among the two metal blocks 2. A threaded ring 4 is arranged on the left side of the connecting pipe 3. A connecting ring 5 is rotatably connected to the left side of the threaded ring 4. Two groups of air cushions 7 are fixedly connected to the surfaces of the two metal blocks 2. First chucks 10 are opened on the upper surfaces of the two metal blocks 2. Blocks 13 are fixedly connected to the lower surfaces of the two connection blocks 8. The two blocks 13 are respectively movably connected to the two first chucks 10. When in use, first, the two metal blocks 2 are stuffed into the inner cavity of the airbag 1 to be demolded, and it is necessary to ensure that the metal blocks 2 are closely fitted with the airbag 1. Then, a vacuum pipeline 6 is connected to the connecting pipe 3 arranged in the left metal block 2 to evacuate the airbag 1 until the airbag 1 is completely deflated. By evacuating the airbag 1, it is separated from the inner cavity of the longeron. After the airbag 1 is completely separated from the longeron, at this time, it is very easy to pull out the airbag 1, and there will be no residues in the inner cavity. The overall structure improves the demolding efficiency of the airbag 1 through auxiliary tools, reduces the risk of residues in the inner cavity, and ensures the quality of the parts.
[0024] On the upper surfaces of the two fixing blocks 15, springs 16 are fixedly connected respectively. The two springs 16 are respectively fixedly connected to the two second chucks 12. Two third chucks 17 are opened on the inner walls of the two second chucks 12. The two pairs of third chucks 17 are respectively movably clamped with the two handle blocks 9. Two groups of air cushions 7 are arranged on the surfaces of the two metal blocks 2 to ensure tightness during connection and increase the friction at the connection.
[0025] A vacuum pipeline 6 is fixedly connected to the left end of the connecting ring 5. A group of limiting blocks 14 are fixedly connected to the lower surfaces of the two fixing blocks 15 respectively. A threaded groove 11 is opened on the surface of the connecting pipe 3. The threaded groove 11 is threadedly sleeved with the threaded ring 4. Pull up the handle block 9 to move the fixing block 15 fixed thereto together, compressing the spring 16. At this time, move the connection block 8 to the connection between the airbag 1 and the metal block 2. The elastic force of the spring 16 drives the fixing block 15 to reset. The fixing block 15 is clamped with the upper surface of the airbag 1 through a group of limiting blocks 14 fixed thereto. Through this structure, the connection between the metal block 2 and the airbag 1 is further ensured to be stable, so that the metal block 2 will not move easily, thereby improving the overall demolding efficiency.
[0026] Working principle:
[0027] During use, first insert two metal blocks 2 into the inner cavity of the airbag 1 to be demolded. It is necessary to ensure that the metal blocks 2 are closely fitted with the airbag 1. Then connect the vacuum pipeline 6 to the connecting pipe 3 provided in the left metal block 2 to evacuate the airbag 1 until the airbag 1 is completely deflated. By evacuating the airbag 1, it is separated from the inner cavity of the stringer. After the airbag 1 is completely separated from the stringer, it will be very easy to pull out the airbag 1 at this time, and there will be no residue in the inner cavity. The overall structure improves the demolding efficiency of the airbag 1, reduces the risk of residue in the inner cavity, and ensures the quality of the part through auxiliary tools. Two groups of air cushions 7 are provided on the surfaces of the two metal blocks 2 to ensure tightness during connection and increase the friction at the connection. After the connection is completed, pull up the handle block 9 to move the fixed block 15 fixed to it together, compressing the spring 16. At this time, move the connecting block 8 to the connection between the airbag 1 and the metal block 2, and the elastic force of the spring 16 drives the fixed block 15 to reset. The fixed block 15 is clamped with the upper surface of the airbag 1 through a group of limit blocks 14 fixed below it. This structure further ensures the stability of the connection between the metal block 2 and the airbag 1, making the metal block 2 not move easily, thus improving the overall demolding efficiency.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
