[0030] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] See also Figures 1 to 6 As shown, the present invention provides a bending device, comprising: a feeding mechanism 1, including a storage section 2 and a feeding section 3; a feeding mechanism 4, including a feeding platform 5, a base 6 and a feeding section 7, wherein the feeding section 3 is configured to transport the workpiece 27 to be bent in the storage section 2 to the feeding platform 5, the feeding platform 5 is configured to be movable relative to the base 6 in a first direction, the feeding section 7 is disposed on the feeding platform 5 and is configured to be movable relative to the feeding platform 5 in a second direction; and a bending mechanism 8, including a bending section 9 and a fixing mold 10, wherein the fixing mold 10 is provided with a receiving groove 11, and the bending section 9 is configured to be movable toward or away from the receiving groove 11 to press the workpiece 27 to be bent into the receiving groove 11.

[0032] In this embodiment, the storage section 2 stores the workpiece 27 to be bent. The loading section 3 can transport the workpiece 27 to be bent from the storage section 2 to the feeding table 5. The feeding table 5 moves the workpiece 27 to be bent relative to the base 6 in a first direction to the position of the bending mechanism 8. Then, the feeding section 7 moves relative to the feeding table 5 in a second direction. During the movement, the feeding table 5 can push the workpiece 27 to be bent onto the fixed mold 10 and push the workpiece 27 to be bent to the position of the receiving groove 11. The receiving groove 11 is opened on the end face of the fixed mold 10 facing the bending part 9. The bending part 9 can move towards the receiving groove 11 and extend into the receiving groove 11. When the workpiece 27 to be bent is pushed to the position of the receiving groove 11 by the feeding part 7, both ends of the workpiece 27 rest on the end face of the fixed mold 10 facing the bending part 9, and the middle of the workpiece is exactly above the receiving groove 11. This causes the bending part 9 to move closer to the receiving groove 11, gradually approaching the workpiece 27 and continuously squeezing it until the workpiece 27 is deformed and bent into the receiving groove 11, thus realizing the bending operation of the workpiece 27. The degree to which the bending part 9 enters the receiving groove 11 varies, and the degree to which the workpiece 27 is bent varies. In practical applications, the depth of the bending part 9 entering the receiving groove 11 can be set to achieve different degrees of bending of the workpiece 27. Through the above settings, automatic feeding and bending can be realized. Both feeding and bending operations do not require manual intervention, resulting in a high degree of automation and significantly improving production efficiency.

[0033] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the bending mechanism 8 further includes a shaping part 12 and a positioning part 13. The shaping part 12 and the positioning part 13 are respectively disposed on opposite sides of the fixed mold 10. The positioning part 13 includes a positioning hole 14, the shaping part 12 includes a shaping post 15, and the bending part 9 includes a through groove 16. The end of the shaping post 15 near the positioning part 13 is configured to pass through the through groove 16 and then into the positioning hole 14. The shaping part 12 further includes a first driving part 17. The driving end of the first driving part 17 is drivenly connected to the shaping post 15 to drive the shaping post 15 to move along a first direction. The positioning part 13 further includes a second driving part 18. The driving end of the second driving part 18 is provided with a positioning plate 19. The positioning hole 14 is disposed on the positioning plate 19. The driving end of the second driving part 18 is configured to drive the positioning plate 19 to move along the first direction.

[0034] In this embodiment, the shaping part 12 is suitable for bending parts 27 (such as those with the same size circular holes at both ends) that are to be bent. Figure 1(The part to be bent, 27). It should be noted that after bending, the centers of the circular holes at both ends of the part to be bent, 27 can be aligned, indicating that the part to be bent, 27 is bent in place. At this time, the appearance of the part to be bent, 27 meets the process requirements. After the part to be bent, 27 is conveyed to the fixed mold, 10 by the feeding part 7, the driving end of the second driving part 18 drives the positioning plate 19 to move along the first direction. The positioning plate 19 pushes the part to be bent, 27, along the first direction, so that the part to be bent, 27 can be aligned with the bending part 9 located above it. This can improve the bending quality of the part to be bent, 27, and also avoid mechanical injury to the human body caused by manual support of the workpiece.

[0035] After the workpiece 27 to be bent is first bent by the bending section 9, the first driving section 17 drives the shaping column 15 to move along the first direction. At this time, the shaping column 15 gradually approaches the positioning section 13. During the movement, the shaping column 15 passes through the round hole at the end of the workpiece 27 closest to the first driving section 17, the through groove 16 on the bending section 9, and the round hole at the end of the workpiece 27 away from the first driving section 17, and then inserts into the positioning hole 14. Through the cooperation of the shaping column 15 and the positioning hole 14, the second bending of the workpiece 27 is finally achieved. During the second bending process, the shaping column 15 can pass through the round hole at one end of the workpiece 27 and exit through the round hole at the other end of the workpiece 27, realizing the shaping and adjustment of both ends of the workpiece 27. This can greatly improve the bending accuracy, ensure that the workpiece 27 is bent in place, ensure the consistency of bending, reduce the defect rate, and make the appearance of the bent workpiece 27 meet the process requirements.

[0036] In one embodiment, the bending mechanism 8 further includes two fixing frames 58, and the first driving part 17 and the second driving part 18 are both fixedly mounted on the fixing base 49 by a fixing frame 58.

[0037] In one embodiment of the present invention, the end of the shaping column 15 facing the positioning part 13 is an arc surface or a spherical surface.

[0038] In this embodiment, the shaping part 12 is suitable for bending parts 27 (such as those with the same size circular holes at both ends) that are to be bent. Figure 1 The forming post 15 has an arc or spherical end facing the positioning part 13, which can guide the forming post 15 so that the end of the forming post 15 near the positioning part 13 can pass through the round holes at both ends of the forming post 27, thereby realizing the secondary bending of the forming post 27.

[0039] See also Figures 1 to 6As shown, in one embodiment of the present invention, the feeding mechanism 1 further includes a workbench 20. Both the storage section 2 and the feeding section 3 are mounted on the workbench 20. The storage section 2 includes a first storage segment 21 and a second storage segment 22 arranged at intervals along a first direction. The first storage segment 21 and / or the second storage segment 22 can move towards or away from each other, forming a storage space 23 between them. The feeding section 3 includes a feeding rod 24, which is configured to extend into the storage space 23 and move along the first direction. The bending device further includes a heating pipe 25 located between the storage section 2 and the feeding table 5. The bottom of the storage section 2 has a discharge port 26, which communicates with the heating pipe 25. The distance between the end of the heating pipe 25 away from the storage section 2 and the feeding table 5 is less than or equal to half the length of the workpiece 27 to be bent.

[0040] In this embodiment, the first storage compartment 21 and the second storage compartment 22 are arranged at intervals along a first direction, forming a storage space 23 between them for storing the parts to be bent 27. The first storage compartment 21 and the second storage compartment 22 extend vertically, enabling multiple parts to be bent 27 to be stacked vertically within the storage space. The first storage compartment 21 and / or the second storage compartment 22 can move closer to or further away from each other to accommodate the placement of parts to be bent 27 of different lengths.

[0041] The bottom of the storage section 2 is provided with a discharge port 26, that is, the bottom of both the first storage section 21 and the second storage section 22 are provided with discharge ports 26. The feeding rod 24 moves along the first direction. The end of the feeding rod 24 near the storage section 2 can extend into the storage space 23 through the discharge port 26 at the bottom of the first storage section 21. After the feeding rod 24 extends into the storage space 23, it can push the bottommost piece to be bent 27, pushing the piece to be bent 27 out of the discharge port 26 at the bottom of the second storage section 22. Since the heating pipe 25 is connected to the discharge port 26 at the bottom of the second storage section 22, the feeding part continues to move along the first direction, and the feeding rod 24 can push the piece to be bent 27 into the heating pipe 25. The heating pipe 25 is provided with an electromagnetic induction coil, which can heat the piece to be bent 27. Through the above settings, automatic feeding can be achieved, and one piece to be bent 27 can be conveyed into the heating pipe 25 at a time. In addition, the distance between the end of the heating pipe 25 away from the storage section 2 and the feeding table 5 is less than or equal to half the length of the part to be bent 27, to prevent the part to be bent 27 from flipping and falling off the feeding table 5.

[0042] See also Figures 1 to 6As shown, in one embodiment of the present invention, the first storage compartment 21 and the second storage compartment 22 each include a first adjusting plate 28 and two second adjusting plates 29 arranged opposite to each other along the second direction. The first adjusting plate 28 is located between the two second adjusting plates 29, and the three together form a U-shaped groove. The first adjusting plate 28 can slide relative to the second adjusting plates 29 in a direction closer to or farther from the worktable 20.

[0043] In this embodiment, the first adjusting plate 28 is located between the two second adjusting plates 29, and the three together form a U-shaped groove. After the bending part 27 is placed into the storage space, the two ends of the bending part 27 are respectively located in the two U-shaped grooves. The first adjusting plate 28 can slide relative to the second adjusting plate 29 towards or away from the worktable 20 to adjust the height of the discharge port 26, thereby making it suitable for bending parts 27 of different thicknesses.

[0044] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the second adjusting plate 29 includes an outer plate 30 of the first storage compartment 21 and an inner plate 31 of the first storage compartment 21. The outer plate 30 is fixedly installed on the workbench 20. A first guide post 32 is fixedly connected to the side of the inner plate 31 facing the outer plate 30. The outer plate 30 is provided with a through hole. The first guide post 32 is provided in a one-to-one correspondence with the through hole. The first guide post 32 is constructed to pass through the through hole and can slide relative to the through hole along its axial direction, so as to drive the inner plate 31 to slide relative to the outer plate 30.

[0045] In this embodiment, for the second adjusting plate 29 of the first storage section 21, the outer plate 30 is located outside the first storage section 21, and the inner plate 31 is located inside the first storage section 21. For the second adjusting plate 29 of the second storage section 22, the outer plate 30 is located outside the second storage section 22, and the inner plate 31 is located inside the second storage section 22. The storage section 2 also includes a plurality of adjusting members 61, and each inner plate 31 is provided with an adjusting member 61. Each outer plate 30 is provided with a threaded hole at a corresponding position. One end of the adjusting member 61 passes through the outer plate 30 and the inner plate 31 in sequence and is threadedly connected to the inner plate 31 and the outer plate 30. Since the outer plate 30 is fixedly installed on the worktable 20, rotating the adjusting member 61 can drive the inner plate 31 to move closer to or away from the worktable 20. After the bending part 27 is inserted into the storage space 23, one end of the bending part 27 is secured between the two inner plates 31 of the first storage section 21, and the other end of the bending part 27 is secured between the two inner plates 31 of the second storage section 22. Through this arrangement, the distance between the two inner plates 31 on the first and second storage sections 21 can be adjusted, thereby making the storage section 2 suitable for bending parts 27 of different widths. The first guide post 32 serves a guiding and connecting function. The first guide post 32 passes through the through hole, allowing the inner plate 31 to be mounted on the outer plate 30. When the adjusting member 61 moves the inner plate 31 closer to or further away from the outer plate 30, the first guide post 32 also provides guidance, ensuring that the relative position of the inner plate 31 and the outer plate 30 changes only in the second direction.

[0046] In one embodiment, the adjusting element 61 can be a bolt or a screw.

[0047] See also Figures 1 to 6 As shown, in one embodiment of the present invention, a protrusion 33 is provided at the end of the first adjusting plate 28 away from the worktable 20. The protrusion 33 extends from the side of the first adjusting plate 28 in a direction away from the first adjusting plate 28. A first limiting groove 34 is provided at the end of the second adjusting plate 29 away from the worktable 20. The protrusion 33 is configured to engage with the first limiting groove 34.

[0048] The above settings can limit the first adjusting plate 28 in the vertical direction. When the first adjusting plate 28 wears down due to long-term use and can no longer slide tightly with the second adjusting plate 29, it can slide down in the vertical direction, thus limiting the first adjusting plate 28 and preventing it from sliding onto the worktable 20 and damaging the worktable 20 or the components located on it.

[0049] See also Figures 1 to 6As shown, in one embodiment of the present invention, the feeding mechanism 4 further includes a guide structure 35, which is mounted on the feeding table 5. The guide structure 35 includes a first guide segment 36 and a second guide segment 37. The first guide segment 36 and the second guide segment 37 are arranged at intervals along a second direction. The first guide segment 36 includes a first guide section 38, and the second guide segment 37 includes a second guide section 39. The first guide section 38 and the second guide section 39 extend along a first direction and are capable of guiding the workpiece 27 to be bent.

[0050] In this embodiment, by setting the first guide section 38 and the second guide section 39, it can be ensured that the part to be bent 27 will not deviate in the second direction during the process of being pushed to the feeding table 5 by the feeding rod 24.

[0051] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the feeding mechanism 4 further includes a stop structure 40, which is mounted on the feeding table 5. The stop structure 40 and the guide structure 35 are arranged opposite to each other. The stop structure 40 is located on the side of the guide structure 35 away from the feeding mechanism 1. The stop structure 40 includes a stop block 41. A second limiting slot 42 is provided on the feeding table 5. The stop block 41 is mounted on the feeding table 5 through the second limiting slot 42. The stop block 41 is configured to be able to move relative to the second limiting slot 42 in a first direction.

[0052] In this embodiment, the stop block 41 is located on the opposite side of the guide structure 35. The stop block 41 is configured to limit the bending part 27 in the first direction, ensuring that the bending part 27 exiting the heating pipe 25 is not pushed out of the feeding table 5. The stop block 41 can move relative to the second limiting slot 42 in the first direction, thereby adjusting the position of the stop block 41 on the feeding table 5, and thus achieving the stopping and limiting of bending parts 27 of different lengths.

[0053] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the stop structure 40 further includes an adjusting rod 43 and a mounting plate 44. The mounting plate 44 is mounted on the feeding table 5. One end of the adjusting rod 43 is threadedly connected to the mounting plate 44, and the other end of the adjusting rod 43 is threadedly connected to the stop block 41. The adjusting rod 43 rotates to drive the stop block 41 to move along the extension direction of the second limiting groove 42.

[0054] With the above settings, the position of the stop block 41 on the feeding table 5 can be adjusted so that the stop block 41 can stop and limit the bending of parts 27 of different lengths.
