[0002] Most corrugated pipes are used as flexible compensation elements. With the development of technology, corrugated pipes are increasingly used in high-precision and sophisticated fields, and their uses are also different. For example, in the aerospace field, corrugated pipes are used to make pressure-sensitive elements.

With the increasing requirement for the use precision of corrugated pipes, the requirements for corrugated pipe forming equipment are also becoming more and more stringent, and corrugated pipes with better precision need to be formed to meet the needs of scientific and technological development.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-4 , the present invention provides a technical solution: a vertical corrugated pipe hydraulic forming device, including a base 1, a plurality of support rods 2 are fixedly installed on the top of the base 1, a limiting plate 3 is fixedly connected to the top of the support rod 2, and a forming mechanism 4 for forming a corrugated pipe is fixedly installed on the top of the limiting plate 3.

[0019] Among them, the provided bearing mechanism 6 can fix the corrugated pipe to be processed. Subsequently, the driving mechanism 5 is started to drive the forming mechanism 4 to reciprocate, so that the wave crest of the corrugated pipe can be formed. Subsequently, the bearing mechanism 6 drives the corrugated pipe to rotate, so that it can cooperate with the forming mechanism 4 to make the wave crest formation more uniform and accurate. When a group of wave crests are processed, the bearing mechanism 6 drives the corrugated pipe to move upward, and then another group of wave crests on the corrugated pipe can be formed. Such a forming device has a relatively high degree of automation and relatively accurate processing accuracy.

[0020] Please refer to Figure 1 and Figure 4, two sets of mounting brackets 26 are fixedly installed on the top of the bearing plate 21. A clamping cylinder 27 is fixedly installed on the mounting bracket 26. The output end of the clamping cylinder 27 is fixedly connected with a clamping block 28. The bearing mechanism 6 includes a moving plate 19, a connecting shaft 20 and a bearing plate 21. The moving plate 19 and the bearing plate 21 are sleeved outside the mounting tube 7. Multiple connecting shafts 20 are fixedly installed on the top of the moving plate 19. A limiting groove for rotatably connecting with the connecting shaft 20 is opened at the bottom of the bearing plate 21. A first gear disk 22 is fixedly connected to the bottom of the bearing plate 21. A driving motor 23 is fixedly installed at the bottom of the moving plate 19. The output end of the driving motor 23 is fixedly connected with a second gear disk 24 meshing with the first gear disk 22. Two second driving cylinders 25 are fixedly connected to the bottom of the limiting plate 3. The output end of the second driving cylinder 25 is fixedly connected with the moving plate 19.

[0021] Among them, the corrugated pipe to be processed is passed through the forming mechanism 4 and placed above the bearing plate 21. Subsequently, the clamping cylinder 27 drives the clamping block 28 to operate, so that the bottom of the corrugated pipe can be fixedly clamped by the clamping block 28.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the forming mechanism 4 includes a mounting tube 7, a first connecting rod 8, a fixing ring 9 and a forming ring 12. The mounting tube 7 is fixedly installed on the top of the limiting plate 3. A fixing ring 9 is fixedly connected inside the mounting tube 7 through two first connecting rods 8. Multiple sliding grooves 10 are penetrated and opened at the top of the side wall of the mounting tube 7. A moving rod 11 is slidably connected inside the sliding groove 10. A forming ring 12 is fixedly connected to one side of the moving rod 11. A driving plate 13 is fixedly connected to the other side of the moving rod 11. A guiding groove 14 is opened at one side of the top of the driving plate 13. The driving plate 13 is fixedly connected with the fixing ring 9 through a return spring 15. The driving mechanism 5 includes a second connecting rod 16, a driving seat 17 and a first driving cylinder 18. A second connecting rod 16 is slidably connected inside the fixing ring 9. The top of the second connecting rod 16 is fixedly connected with a driving seat 17 fitting with the guiding groove 14. The driving seat 17 is arranged in a frustum shape. A first driving cylinder 18 is fixedly installed on the top of the base 1. The output end of the first driving cylinder 18 is fixedly connected with the second connecting rod 16.

[0023] After the corrugated pipe is fixed, the first driving cylinder 18 is started to operate. The first driving cylinder 18 drives the second connecting rod 16 and the driving seat 17 to move downward along the fixed ring 9. Subsequently, the frustum-shaped driving seat 17 drives the moving rod 11, the forming ring 12 and the driving plate 13 to move along the chute 10, so that the forming ring 12 can perform hydraulic forming on the corrugated pipe. During the forming process, the first driving cylinder 18 moves repeatedly. When the second driving cylinder 18 extends, the return spring 15 can drive the moving rod 11, the forming ring 12 and the driving plate 13 to retract. At this time, the driving motor 23 is started to operate, and the driving motor 23 drives the first gear disk 22 and the bearing plate 21 to rotate along the connecting shaft 20 by means of the second gear disk 24. Such rotational forming can facilitate the precise forming of the corrugated pipe wave crest. After one set of wave crests is formed, the second driving cylinder 25 can push the moving plate 19 and the bearing plate 21 upward, so that the forming process can be carried out on the position of another wave crest of the corrugated pipe.

[0024] Please refer to Figure 1 and Figure 4 The manufacturing materials of the mounting pipe 7, the forming ring 12 and the bearing plate 21 are all stainless steel materials. A rubber pad is laid at one end of the clamping block 28 away from the output end of the clamping cylinder 27. The mounting pipe 7, the forming ring 12 and the bearing plate 21 made of stainless steel materials can prevent the corrugated pipe from being contaminated during the forming process, while the rubber pad provided at one end of the clamping block 28 can prevent the corrugated pipe from being scratched during positioning.

[0025] During use, first, the corrugated pipe to be processed is passed through the forming mechanism 4 and placed above the bearing plate 21. Subsequently, the clamping cylinder 27 drives the clamping block 28 to operate, so that the bottom of the corrugated pipe can be fixedly clamped by the clamping block 28. After the corrugated pipe is fixed, the first driving cylinder 18 is started to operate. The first driving cylinder 18 drives the second connecting rod 16 and the driving seat 17 to move downward along the fixed ring 9. Subsequently, the frustum-shaped driving seat 17 drives the moving rod 11, the forming ring 12 and the driving plate 13 to move along the chute 10, so that the forming ring 12 can perform hydraulic forming on the corrugated pipe. During the forming process, the first driving cylinder 18 moves repeatedly. When the second driving cylinder 18 extends, the return spring 15 can drive the moving rod 11, the forming ring 12 and the driving plate 13 to retract. At this time, the driving motor 23 is started to operate, and the driving motor 23 drives the first gear disk 22 and the bearing plate 21 to rotate along the connecting shaft 20 by means of the second gear disk 24. Such rotational forming can facilitate the precise forming of the corrugated pipe wave crest. After one set of wave crests is formed, the second driving cylinder 25 can push the moving plate 19 and the bearing plate 21 upward, so that the forming process can be carried out on the position of another wave crest of the corrugated pipe.

[0026] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
