[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a flexible bending device for a reversing chain, including a bending machine body 1. A controller 2 is installed on one side of the bending machine body 1. A lower mounting seat 3 is installed on the lower inner side of the bending machine body 1. A lower mold 4 is installed above the lower mounting seat 3. An adjustment mechanism is provided below the lower mounting seat 3. A hydraulic cylinder 5 is installed at the top inner side of the bending machine body 1. An upper mounting seat 6 is installed at the bottom end of the hydraulic cylinder 5. An upper mold 7 is installed below the upper mounting seat 6. An installation mechanism is provided inside the upper mounting seat 6. An elastic pad is provided on the inner side of the lower mold 4, which can perform flexible bending processing on the reversing chain.

[0020] The adjustment mechanism includes a servo motor 11, a threaded rod 12, a threaded sleeve 13, a limiting rod 14, a limiting sleeve 15, and a replacement component. The servo motor 11 is installed at the front end of the bending machine body 1. The threaded rod 12 is installed inside the lower part of the bending machine body 1, and the output end of the servo motor 11 is connected to one end of the threaded rod 12. A threaded sleeve 13 is provided on the outer wall of the threaded rod 12, and the top end of the threaded sleeve 13 is connected to the bottom end of the lower mounting base 3. The limiting rod 14 is installed on both sides inside the lower part of the bending machine body 1, and a limiting sleeve 15 is provided on the outer wall of the limiting rod 14. The top end of the limiting sleeve 15 is connected to the bottom end of the lower mounting base 3. The cross-section of the limiting rod 14 is smaller than the cross-section of the limiting sleeve 15. The limiting rod 14 and the limiting sleeve 15 are connected. The sleeves 15 form a sliding structure. In use, the servo motor 11 is started to drive the threaded rod 12 to rotate, which in turn drives the threaded sleeve 13 to move. Under the limitation of the limiting rod 14 and the limiting sleeve 15, the threaded sleeve 13 drives the lower mounting base 3 to move, which in turn drives the lower mold 4 to move. The operator can move the appropriate lower mold 4 to below the upper mold 7 according to the actual needs. At this time, the universal chain can be flexibly bent to adjust the position of the lower mounting base 3, and then adjust the position of the two lower molds 4 above the lower mounting base 3. The appropriate lower mold 4 can be moved to below the upper mold 7 according to the actual needs, making it more convenient and faster to change the lower mold 4, thereby greatly improving the working efficiency of the equipment during use.

[0021] The replacement component includes a fixed rail 8, a positioning hole 9, and a positioning pin 10. The fixed rail 8 is disposed inside the lower mounting base 3, and its top end is connected to the bottom end of the lower mold 4. The lower mounting base 3 and the fixed rail 8 are provided with positioning holes 9, and positioning pins 10 are disposed inside the positioning holes 9. The positioning holes 9 and positioning pins 10 are mutually adapted to each other and form a locking structure. When the lower mold 4 needs to be replaced, the positioning pins 10 are removed from the positioning holes 9, and the fixed rail 8 can be removed from the lower mounting base 3. Then, the new fixed rail 8 is placed into the lower mounting base 3, and the positioning pins 10 are used to fix the fixed rail 8, thus completing the convenient replacement of the lower mold 4.

[0022] The mounting mechanism includes a connecting block 16, a positioning plate 17, a threaded hole 18, a screw 19, a rotating wheel 20, a guide hole 21, and a guide rod 22. The connecting block 16 is disposed inside the upper mounting base 6, and its bottom end is connected to the top end of the upper mold 7. A threaded hole 18 is provided through the middle position of the front end of the upper mounting base 6, and a screw 19 is provided through the threaded hole 18. A rotating wheel 20 is installed at one end of the screw 19, and a positioning plate 17 is rotatably installed at the other end of the screw 19. A guide hole 21 is provided at the front end of the upper mounting base 6, and a guide rod 22 is provided through the guide hole 21. One end of the guide rod 22 is connected to the positioning plate 17. One end of plate 17 is connected. When the upper mold 7 needs to be replaced, the rotating wheel 20 drives the screw 19 to rotate. Since the threaded hole 18 and the screw 19 form a threaded connection, under the limit of the guide hole 21 and the guide rod 22, the screw 19 drives the positioning plate 17 to move. At this time, the connecting block 16 and the upper mold 7 can be removed. Then, the new upper mold 7 can be taken out, the connecting block 16 can be placed into the interior of the upper mounting base 6, and the rotating wheel 20 is reversed to drive the screw 19 to rotate, so that the positioning plate 17 and the connecting block 16 fit together, and the position of the upper mold 7 is fixed, thus completing the convenient installation of the upper mold 7, which greatly improves the convenience of the equipment during use.

[0023] Two guide rods 22 are provided at one end of the positioning plate 17. The two guide rods 22 are symmetrically distributed about the central axis of the positioning plate 17. In use, the guide hole 21 and the guide rod 22 cooperate with each other to guide the positioning plate 17 when it moves, making the positioning plate 17 more stable when it moves.

[0024] Working principle: The operator first starts the servo motor 11 to drive the threaded rod 12 to rotate, which in turn drives the threaded sleeve 13 to move. Then, under the limit of the limit rod 14 and the limit sleeve 15, the threaded sleeve 13 drives the lower mounting base 3 to move, which in turn drives the lower mold 4 to move. The operator moves the appropriate lower mold 4 to below the upper mold 7 according to actual needs. At this time, the universal chain can be flexibly bent. When the upper mold 7 needs to be replaced, the rotating wheel 20 drives the screw 19 to rotate. Since the threaded hole 18 and the screw 19 form a threaded connection, under the limit of the guide hole 21 and the guide rod 22, the screw 19 drives the positioning plate 17 to move. At this time, the connecting block 16 and the upper mold 7 can be removed. Then, the new upper mold 7 is taken out, and the connecting block 16 is placed inside the upper mounting base 6. The rotating wheel 20 is reversed to drive the screw 19 to rotate, so that the positioning plate 17 and the connecting block 16 fit together, fixing the position of the upper mold 7 and completing the convenient installation of the upper mold 7.
