The bottom of the connector is fixedly mounted in the silicone pressing head. The position of the silicone pressing head corresponds to the top of the silicone shaping head. The parts to be shaped are arranged between the silicone pressing head and the silicone shaping head. Among them, several first linear bearings are arranged in the middle of the pressing seat, the connecting piece in the middle of the silicone pressing head is passed through the first linear bearing, and symmetrically arranged rotating seats are provided on both sides of the pressing seat. The rotating seat can be rotatably installed on the pressing seat, and an oil-free bushing is provided on the rotating seat. The connecting piece at the end of the silicone pressing head is passed through the oil-free bushing.

[0007] As a further description of the above technical solution: The connecting piece comprises a first rod and a spring. The connecting head is rotatably mounted on the end of the first rod. The spring is sleeved on the first rod and rests against the back of the end of the first rod.

[0008] As a further description of the above technical solution: The connecting piece is a nitrogen spring. A second rod body is provided on the back of the housing of the nitrogen spring. The second rod body and the connecting head are rotatably mounted on the second piston rod of the nitrogen spring.

[0009] As a further description of the above technical solution: The connector structure is in an inverted "T" shape, and a base plate embedded in the silicone compression head is provided at the bottom of the connector.

[0010] As a further description of the above technical solution: The bottom surface of the pressing seat is provided with several rotating shaft mounting grooves, and the rotating seat is provided with symmetrically arranged rotating shafts on both sides.

[0011] As a further description of the above technical solution: Two first guide rods are provided on the back of the jacking seat. The two first guide rods are symmetrically arranged on both sides of the first servo electric cylinder. The first guide rods are passed through the first electric cylinder mounting seat.

[0012] As a further description of the above technical solution: A plurality of second guide rods are provided on the back of the pressing seat. The second guide rods are passed through the second electric cylinder mounting seat. The second servo electric cylinder is fixedly mounted on the second electric cylinder mounting seat.

[0013] As a further description of the above technical solution: At least one connecting rod is provided on the back of the silicone shaping head. The connecting rod is plugged into the connecting seat of the mounting seat, and the quick-change pin is passed through the mounting seat and the connecting rod.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, during the shaping process of the part to be shaped, the silicone pressing head cooperates with the silicone shaping head to achieve flexible shaping.

The rotating seat is used to realize the rotation and guidance of the connecting piece at the end of the silicone pressing head, so that the silicone pressing head always keeps in contact with the upper surface of the part to be shaped during the shaping process. At the same time, the connecting piece ensures that the silicone pressing head elastically presses the part to be shaped, effectively ensuring the shaping quality of the part to be shaped, and there is no bending mark after shaping.

[0015] 2. In the present invention, the connector can achieve elastic compression of the part to be shaped using a spring or nitrogen spring. While using a nitrogen spring to achieve elastic compression of the part to be shaped increases costs compared to springs, the elastic compression force of different connectors can be flexibly adjusted according to the shaping requirements of the different specifications of the part to be shaped. Furthermore, unlike springs, whose elastic compression effect irreversibly changes with the number of shaping cycles, nitrogen springs can adjust the air pressure to ensure a constant elastic compression effect even after long-term use, ensuring a stable shaping effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention. Example

[0025] See also Figure 1-5 The present invention provides a technical solution: a flexible shaping device for aluminum alloy thin shell parts, comprising: The shaping module 1 includes a first servo electric cylinder 11, a lifting seat 12, a mounting seat 13, a driving cylinder 14 and a silicone shaping head 15. The lifting seat 12 is fixedly mounted on the push rod of the first servo electric cylinder 11, the mounting seat 13 is slidably connected to the lifting seat 12, the driving cylinder 14 is fixedly mounted on the lifting seat 12, the first piston rod of the driving cylinder 14 passes through the side wall of the lifting seat 12 and is connected to the mounting seat 13, the silicone shaping head 15 is fixedly mounted on the mounting seat 13, and the top of the silicone shaping head 15 is a convex arc surface; The pressing module 2 includes a second servo electric cylinder 21, a pressing seat 22, a connecting piece 23 and a silicone pressing head 24. The pressing seat 22 is fixedly mounted on the push rod of the second servo electric cylinder 21. A plurality of connecting pieces 23 arranged in parallel are provided on the back of the silicone pressing head 24. The connecting piece 23 is elastically connected to the pressing seat 22. A connecting head 231 is provided at the bottom of the connecting piece 23. The connecting head 231 is rotatably mounted on the connecting piece 23. The bottom of the connecting head 231 is fixedly mounted in the silicone pressing head 24. The position of the silicone pressing head 24 corresponds to the top of the silicone shaping head 15. The part 9 to be shaped is arranged between the silicone pressing head 24 and the silicone shaping head 15. Among them, several first linear bearings 221 are arranged in the middle of the clamping seat 22, and the connecting piece 23 in the middle of the silicone clamping head 24 is passed through the first linear bearing 221. Symmetrically arranged rotating seats 222 are provided on both sides of the clamping seat 22. The rotating seat 222 can be rotatably installed on the clamping seat 22. An oil-free bushing 223 is provided on the rotating seat 222, and the connecting piece 23 at the end of the silicone clamping head 24 is passed through the oil-free bushing 223.

[0026] During the shaping process of the part 9 to be shaped, the silicone pressing head 24 cooperates with the silicone shaping head 15 to achieve flexible shaping. When the silicone shaping head 15 pushes the part 9 to be shaped upward, the part 9 to be shaped bulges upward. On the one hand, the silicone pressing head 24 deforms by utilizing the characteristics of its own silicone material. On the other hand, the connecting piece 23 in the middle of the silicone pressing head 24 is pushed upward and guided by the first linear bearing 221, and the connecting piece 23 at the end of the silicone pressing head 24 rotates with the deformation of the silicone pressing head 24. The rotating seat 222 is used to realize the rotation and guidance of the connecting piece 23 at the end of the silicone pressing head 24, so that the silicone pressing head 24 always keeps in contact with the upper surface of the part 9 to be shaped during the shaping process. At the same time, the connecting piece 23 ensures that the silicone pressing head 24 elastically presses the part 9 to be shaped, effectively ensuring the shaping quality of the part 9 to be shaped, and there is no bending mark after shaping.

[0027] The connector 231 is in an inverted T-shape, and a bottom plate 2311 is provided at the bottom of the connector 231, which is embedded in the silicone pressing head 24. When the silicone pressing head 24 is deformed during the shaping process, the bottom plate 2311 effectively prevents the connector 231 from separating from the silicone pressing head 24.

[0028] Two first guide rods 121 are provided on the back of the lifting base 12. These rods 121 are symmetrically arranged on either side of the first servo cylinder 11 and extend through the first cylinder mounting base 16. The first cylinder mounting base 16 is used to secure the first servo cylinder 11. Through these first guide rods 121, the first cylinder mounting base 16 ensures smooth lifting of the lifting base 12, preventing deflection and ensuring the quality of shaping performed by the silicone shaping head 15.

[0029] A plurality of second guide rods 226 are provided on the back of the pressing seat 22. The second guide rods 226 are passed through the second electric cylinder mounting seat 227. The second servo electric cylinder 21 is fixedly mounted on the second electric cylinder mounting seat 227, which effectively ensures the smooth lifting and lowering of the pressing seat 22, avoids the deflection of the pressing seat 22, and effectively ensures the shaping quality.

[0030] Working principle: After sandblasting, the thin shell part 9 made of aluminum alloy is bent and deformed downward. When it is moved to the flexible shaping device for shaping, the four inner corners of the part 9 to be shaped are clamped and positioned. Then, the second servo electric cylinder 21 of the clamping module 2 drives the clamping seat 22 downward, so that the silicone clamping head 24 moves downward and contacts the upper surface of the part 9 to be shaped. Then, the first servo electric cylinder 11 in the shaping module 1 drives the lifting seat 12 upward, so that the silicone clamping head 24 moves upward and squeezes the part 9 to be shaped, completing the shaping of the part 9 to be shaped. Example

[0031] This embodiment further provides the following improved technical solutions based on the above-mentioned embodiment 1: the connector 23 includes a first rod 232 and a spring 233. The connector 231 is rotatably mounted on the end of the first rod 232. The spring 233 is sleeved on the first rod 232 and abuts against the back of the end of the first rod 232. The connector 23 can use the spring 233 to press the silicone pressing head 24 against the part to be shaped 9. This structure is simple, low-cost, and easy to replace.

[0032] For the connecting piece 23 at the end of the silicone pressing head 24, the upper part of the first rod body 232 passes through the rotating seat 222 and is connected to the first locking block 234. The first locking block 234 prevents the first rod body 232 from moving downward and separating from the rotating seat 222. One end of the spring 233 contacts the back side of the end of the first rod body 232 and the other side contacts the rotating seat 222 to achieve an elastic connection.

[0033] Similarly, when the connecting piece 23 in the middle of the silicone pressing head 24 is installed, the upper portion of the first rod 232 passes through the first linear bearing 221 and connects to the second locking block to prevent the first rod 232 from moving downward and separating from the first linear bearing 221 . Example

[0034] This embodiment further improves upon the above-described embodiment 1 by providing the following technical solutions: Connector 23 is a nitrogen spring, with a second rod disposed on the back of the nitrogen spring housing. The second rod, along with a connector 231, is rotatably mounted on the second piston rod of the nitrogen spring. The second rod on connector 23 at the end of silicone pressure head 24 passes through rotating seat 222 and connects to first locking block 234. The second rod on connector 23 in the middle of silicone pressure head 24 passes through first linear bearing 221 and connects to the second locking block.

[0035] While utilizing a nitrogen spring to achieve elastic compression of the part 9 to be shaped increases costs, the elastic compression force of different connectors 23 can be flexibly adjusted based on the shaping requirements of the different specifications of the part 9 to be shaped. Furthermore, unlike springs 233, whose elastic compression effect irreversibly changes with the number of shaping cycles, nitrogen springs can maintain a constant elastic compression effect over extended periods of use by adjusting the air pressure, ensuring a stable shaping effect. Example

[0036] This embodiment further makes the following improved technical solutions on the basis of the above-mentioned embodiment 1: a plurality of rotating shaft mounting grooves 224 are provided on the bottom surface of the pressing seat 22, and symmetrically arranged rotating shafts 2221 are provided on both sides of the rotating seat 222. The rotating shafts 2221 are placed in the rotating shaft mounting grooves 224, and the pressure plate 225 is fixedly installed on the bottom surface of the pressing seat 22 by bolts. The pressure plate 225 contacts the rotating shaft 2221 to realize the detachable installation of the rotating seat 222, and the pressure plate 225 simultaneously blocks the rotating shafts 2221 of the two rotating seats 222, thereby effectively improving the disassembly and assembly efficiency of the connecting member 23. Example

[0037] This embodiment further makes the following improved technical solutions based on the above-mentioned embodiment 1: at least one connecting rod is provided on the back of the silicone shaping head 15, the connecting rod is inserted into the connecting seat of the mounting seat 13, and the quick-change pin is passed through the mounting seat 13 and the connecting rod.

[0038] The silicone shaping head 15 is connected to the connecting seat on the two parallel connecting rod mounting seats 13 and can be quickly replaced by a quick-change pin, so that a damaged silicone shaping head 15 can be replaced in time.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
