Description

Technical Field

[0001] This invention belongs to the field of auto parts and components, and relates to bending technology, specifically a bending structure for the production of automotive parts. Background Technology

[0002] With the development of new energy vehicles, energy conservation and emission reduction have gradually become mainstream, leading to a surge in the demand for new energy vehicles. The production and design of new energy vehicles involves numerous parts, and bending is a common processing method in automotive parts manufacturing. The principle involves applying force to a metal material, causing plastic deformation, and then bending it into the desired shape through appropriate process control. This processing method is suitable for manufacturing automotive parts that require bending, such as body frames, doors, and seat frames. Bending structures can make parts more compact and lighter, improving the overall performance and fuel efficiency of the vehicle.

[0003] In existing technologies, such as the bending device for processing automotive parts provided by Chinese Patent Publication No. CN217889142U, the bending mechanism first controls the activation of a lifting cylinder, which moves the bending block downwards. When the bending block moves fully downwards into the material loading trough, the bending of the hoop is quickly completed. Then, the displacement cylinder is activated, which moves the force plate downwards. This downward movement of the force plate causes the driven block and the retaining ring to flip to the left simultaneously. The leftward flip of the retaining ring causes the main carrier plate and the material loading trough to flip to the left simultaneously. After the material loading trough has flipped to the left at a certain angle, the bent hoop automatically falls into the guide hopper. Finally, the guide hopper transfers the hoop to the receiving box. However, the above technical solution still has the following problems:

[0004] The applicant believes that by using a displacement cylinder and a force plate to drive the main carrier plate and the material trough to rotate, thereby realizing the material unloading, the main carrier plate will come into contact with the main drive block every time it rotates, which is prone to noise and will also greatly increase the wear of the main drive block and reduce its service life. At the same time, when the main carrier plate rotates to unload material, it is necessary to ensure that the angle between the main carrier plate and the table is large enough; otherwise, the parts will get stuck in the material trough, causing the bent parts to be difficult to unload. Summary of the Invention

[0005] The purpose of this application is to provide a bending structure for the production of automotive parts, which solves the problem that the main carrier tray is prone to noise when turning over to discharge materials, and also aggravates wear.

[0006] To achieve the above objectives, this application provides a bending structure for automotive parts production, including a base plate. The top of the base plate is provided with a bending block and a main carrier plate that are mutually adapted to each other. The main carrier plate is rotatably connected to the base plate. The base plate has movable grooves symmetrically arranged with respect to the main carrier plate. Guide arc segments and guide straight grooves are respectively provided within the movable grooves. A first push rod and a second push rod are respectively provided at the guide straight groove and the guide arc segment. One end of the second push rod is rotatably connected to a movable shaft one guided by the guide arc segment. A connecting rod is rotatably connected to the outside of the movable shaft one. The other end of the connecting rod is provided with a movable shaft two. A movable shaft three guided by the guide straight groove is provided in the middle of the first push rod. A movable shaft four is rotatably connected to one end of the first push rod. A second guide frame and a first guide frame are fixedly connected to the bottom of the base plate. The second guide frame has a first guide groove slidably connected to the movable shaft two. The first guide frame has a second guide groove slidably connected to the movable shaft four. Both the first and second guide grooves are inclined.

[0007] Preferably, the bottom plate is provided with a guide member at one end of the second top rod that is compatible with the movable shaft.

[0008] Preferably, the guide member is provided with a limiting arc segment that limits the movement of the movable shaft.

[0009] Preferably, the top end of the first push rod is provided with an arc block.

[0010] Preferably, a guide rod is provided at the bottom end of the base plate, and an adjustment groove is provided at both ends of the guide rod. The second movable shaft and the fourth movable shaft are slidably connected to the adjustment groove on the corresponding side.

[0011] Preferably, a cylinder for supporting the guide rod is provided between the first push rod and the connecting rod.

[0012] Preferably, one end of the cylinder is rotatably connected to a fixed frame, and the fixed frame is fixedly connected to the base plate.

[0013] Preferably, the first guide groove is L-shaped, the length of the second guide groove is half that of the first guide groove, and the output end of the cylinder is rotatably connected to the guide rod.

[0014] Preferably, a motor is fixedly installed inside the base plate, and the output end of the motor passes through the top of the base plate and is fixedly connected to the main carrier plate.

[0015] Preferably, a top plate is fixedly connected to the top of the base plate, and a telescopic cylinder is fixedly installed at one end of the top plate. The output end of the telescopic cylinder is fixedly connected to the bending block.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By setting a first push rod, a second push rod, and a connecting rod, the first push rod and the connecting rod move upward synchronously. The guide arc segment limits the first movable shaft, the guide straight groove limits the third movable shaft, the second movable shaft slides along the first guide groove, and the fourth movable shaft slides along the second guide groove. The second push rod and the first push rod gradually move into the corresponding side grooves, lifting the end of the original plate of the hoop that extends to the side groove. The original plate of the hoop separates from the groove formed by bending the main carrier plate. The fourth movable shaft moves to the top of the second guide groove and stops moving. The second movable shaft... Moving along the first guide groove toward the guide member, the second movable shaft drives the first movable shaft to move to the arc surface of the guide member via the connecting rod. The first movable shaft drives the second push rod to rotate relative to the connecting rod. The second push rod tilts until it is in contact with the surface of the main carrier plate, causing the hoop plate after being lifted to fall from one side of the second push rod. The second push rod further guides the formed hoop plate, realizing the unloading of the hoop plate without flipping and lifting the main carrier plate, and also avoiding opening holes in the groove of the main carrier plate to avoid affecting the bending effect.

[0018] By setting a guide rod, the cylinder drives the guide rod to move upward through the hinge. The guide rod drives the second and fourth movable shafts to move upward on the same horizontal plane through the adjustment groove until the fourth movable shaft moves to the top of the second guide groove. At this time, the fourth movable shaft is restricted and no longer moves. The cylinder continues to drive the guide rod to move upward through the hinge. The guide rod rotates around the fourth movable shaft. The end of the guide rod facing the second movable shaft tilts up and drives the second movable shaft to move along the first guide groove towards the guide member. The second movable shaft drives the first movable shaft to move to the arc surface of the guide member through the connecting rod. The first movable shaft drives the second push rod and the connecting rod to rotate relative to each other, causing the original plate of the hoop to fall from one side of the second push rod. Thus, the guide rod and the adjustment groove can drive the first push rod and the connecting rod to move synchronously, and at the same time drive the second push rod and the connecting rod to rotate.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Please refer to the details. Figures 1-5A bending structure for automotive parts manufacturing includes a base plate 2. A bending block 5 and a main carrier plate 6 are fitted together at the top of the base plate 2. The bending block 5 and the main carrier plate 6 are movable relative to each other. The main carrier plate 6 is rotatably connected to the base plate 2. The bending block 5 moves toward the main carrier plate 6, bending a pre-placed hoop plate on the surface of the main carrier plate 6. The main carrier plate 6 rotates relative to the base plate 2, thus bending the hoop plate at different positions. Two movable grooves 16 are provided on the base plate 2, symmetrically arranged about the main carrier plate 6. A guide arc segment 21 and a guide straight groove 22 are respectively provided in the two movable grooves 16. A first push rod 13 and a second push rod 14 are respectively provided at the guide straight groove 22 and the guide arc segment 21. One end of the second push rod 14 is rotatable. A movable shaft 15 is connected, and a connecting rod 17 is rotatably connected to the outside of the movable shaft 15. The other end of the connecting rod 17 is rotatably connected to a movable shaft 19. A movable shaft 27 is provided in the middle of the first push rod 13, and a movable shaft 29 is rotatably connected to one end of the first push rod 13. The guide arc segment 21 is adapted to the movable shaft 15, and the guide straight groove 22 is adapted to the movable shaft 27. The bottom end of the base plate 2 is fixedly connected to the second guide frame 18 and the first guide frame 12, respectively. The second guide frame 18 has a first guide groove 20 that is slidably connected to the movable shaft 29, and the first guide frame 12 has a second guide groove 30 that is slidably connected to the movable shaft 29. Both the first guide groove 20 and the second guide groove 30 are inclined.

[0029] When the second movable shaft 19 moves upward along the first guide groove 20, the second movable shaft 19 drives the connecting rod 17 to move upward. The movement of the connecting rod 17 drives the first movable shaft 15 and the second push rod 14 to move upward. The guide arc segment 21 guides the first movable shaft 15, causing the second push rod 14 to move towards the main carrier plate 6 until the second push rod 14 moves into the corresponding side groove 7 and lifts the end of the original plate of the hoop extending into the side groove 7. When the fourth movable shaft 29 moves upward along the second guide groove 30, the fourth movable shaft 29... 9 drives the first push rod 13 to move upward, and the movable shaft 27 moves upward along the guide straight groove 22. The guide straight groove 22 is parallel to the second guide groove 30. Therefore, the first push rod 13 remains vertical throughout its movement until the top of the first push rod 13 moves to the corresponding side groove 7. The top of the first push rod 13 lifts the end of the formed hoop plate located at the end of the side groove 7. The hoop plate is lifted by the first push rod 13 and the second push rod 14, and the hoop plate is separated from the groove formed by the bending of the main carrier plate 6, which facilitates material discharge.

[0030] As one implementation method in this embodiment, such as Figures 2-5As shown, a guide 8 is provided at one end of the base plate 2 located on the second push rod 14. The guide 8 is adapted to the movable shaft 15. When the second push rod 14 and the first push rod 13 simultaneously lift the original plate of the hoop, the movable shaft 15 moves along the arc surface of the guide 8. As the movable shaft 15 drives the junction of the second push rod 14 and the connecting rod 17 to move, the second push rod 14 and the connecting rod 17 rotate around the axis of the movable shaft 15 until the second push rod 14 tilts to fit against the surface of the main carrier plate 6. At this time, the height of the second push rod 14 is lower than the top of the first push rod 13. The lifted original plate of the hoop moves laterally toward the direction of the second push rod 14. The surface of the second push rod 14 guides the original plate of the hoop, thereby promoting... After being lifted, the original hoop plate falls from one side of the second push rod 14, realizing the unloading of the original hoop plate. The top of the first push rod 13 is provided with an arc block 28, which makes it easier to lift the original hoop plate. When the original hoop plate is tilted, it is easier for the original hoop plate to fall. After the original hoop plate is unloaded, the second movable shaft 19 and the fourth movable shaft 29 move down along the first guide groove 20 and the second guide groove 30, respectively. The second movable shaft 19 and the fourth movable shaft 29 drive the first movable shaft 15 and the third movable shaft 27 to move down, and drive the second push rod 14, the connecting rod 17 and the first push rod 13 to be put into the corresponding movable groove 16. At this time, the first push rod 13 and the second push rod 14 will not interfere with the rotation of the main carrier plate 6, and subsequent unloading operations can be carried out.

[0031] As one implementation method in this embodiment, such as Figure 5 and Figure 6 As shown, a limiting arc segment 23 is provided on the guide member 8. When the movable shaft 15 moves to the surface of the guide member 8, the limiting arc segment 23 limits the end of the movable shaft 15 to prevent the movable shaft 15 from moving unevenly. In order to maintain the included angle between the second push rod 14 and the connecting rod 17, a torsion spring can be installed between the second push rod 14 and the connecting rod 17.

[0032] As one implementation method in this embodiment, such as Figure 5 and Figure 6 As shown, a guide rod 24 is provided at the bottom end of the base plate 2. Adjustment grooves 26 are provided at both ends of the guide rod 24. The second movable shaft 19 and the fourth movable shaft 29 are slidably connected to the adjustment grooves 26 on the corresponding sides. The adjustment grooves 26 provide space for the movement of the second movable shaft 19 and the fourth movable shaft 29. By moving the guide rod 24 vertically upward, the guide rod 24 drives the second movable shaft 19 and the fourth movable shaft 29 to move upward, so that the second movable shaft 19 and the fourth movable shaft 29 move upward synchronously, so that the second push rod 14 and the first push rod 13 simultaneously lift up both ends of the original plate of the hoop. A hinge 25 is rotatably connected to the middle of the guide rod 24. A cylinder 10 is provided at the other end of the hinge 25. The output end of the cylinder 10 is fixed to the hinge 25. When the cylinder 10 is started, the cylinder 10 drives the guide rod 24 to lift upward through the hinge 25, so that the second movable shaft 19 and the fourth movable shaft 29 move upward synchronously.

[0033] As one implementation method in this embodiment, such as Figure 1 and Figure 6 As shown, the end of the cylinder 10 away from the hinge 25 is rotatably connected to a fixed frame 11, which is fixedly connected to the base plate 2. The fixed frame 11 is V-shaped.

[0034] As one implementation method in this embodiment, such as Figures 2-6 As shown, the guide rod 24 is V-shaped, and the two guide rods 24 are rotatably connected by a shaft and hinge 25 to improve the stability of the cylinder 10 driving the guide rod 24 upward. The first guide groove 20 is L-shaped, and the length of the second guide groove 30 is half that of the first guide groove 20. When the cylinder 10 drives the guide rod 24 upward via the hinge 25, the guide rod 24 drives the movable shaft 29 and the movable shaft 4 29 upward via the adjusting groove 26. The movable shaft 29 and the movable shaft 4 29 are on the same horizontal plane until the movable shaft 4 29 moves to the top of the second guide groove 30 and stops moving. The cylinder 10 continues to move. The hinge 25 drives the guide rod 24 to move upward. The guide rod 24 rotates around the movable shaft 29 as the center. The end of the guide rod 24 tilts up towards the movable shaft 19 and drives the movable shaft 19 to move along the first guide groove 20 towards the guide member 8. The movable shaft 19 drives the movable shaft 15 to move to the arc surface of the guide member 8 through the connecting rod 17. The movable shaft 15 drives the second push rod 14 to rotate relative to the connecting rod 17. The second push rod 14 tilts to fit against the surface of the main carrier plate 6, causing the hoop original plate to fall from one side of the second push rod 14 after being pushed up, thus realizing the unloading of the hoop original plate.

[0035] As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, a motor 9 is fixedly installed inside the base plate 2. The output end of the motor 9 passes through the top of the base plate 2 and is fixedly connected to the main carrier plate 6. The motor 9 drives the main carrier plate 6 to rotate, thereby bending the original band plate on the surface of the main carrier plate 6 into shape. A top plate 3 is fixedly connected to the top of the base plate 2. A telescopic cylinder 4 is fixedly installed at one end of the top plate 3. The output end of the telescopic cylinder 4 is fixedly connected to the bending block 5. The telescopic cylinder 4 moves towards the groove opened in the main carrier plate 6, thereby realizing the bending and shaping of the original band plate. Support legs 1 are fixedly connected to all four sides of the base plate 2, and the support legs 1 provide support for the base plate 2.

[0036] The working principle of this invention is as follows: When in use, the operator first places the original plate on the main carrier plate 6, starts the telescopic cylinder 4, and the telescopic cylinder 4 drives the bending block 5 to move towards the groove of the main carrier plate 6. The original plate is bent through the bending block 5 and the groove on the surface of the main carrier plate 6. When the main carrier plate 6 is bent in one place, the motor 9 starts and drives the main carrier plate 6 to rotate, thereby moving different positions of the original plate to directly below the bending block 5, which facilitates subsequent bending and forming until the bending process of the original plate is completed.

[0037] When the original plate bends, cylinder 10 is activated, causing guide rod 24 to move upward. Guide rod 24, through adjusting groove 26, causes movable shafts 19 and 29 to move upward, bringing them to the same horizontal plane. Movable shaft 29 moves to the top of the second guide groove 30, at which point it stops moving. Cylinder 10 continues to drive guide rod 24 upward via hinge 25, causing guide rod 24 to rotate around movable shaft 29. The rod 24 tilts up towards one end of the movable shaft 19 and drives the movable shaft 19 to move along the first guide groove 20 toward the guide member 8. The movable shaft 19 drives the movable shaft 15 to move to the arc surface of the guide member 8 through the connecting rod 17. The movable shaft 15 drives the second push rod 14 to rotate relative to the connecting rod 17. The second push rod 14 tilts to fit against the surface of the main carrier plate 6, causing the hoop original plate to fall from one side of the second push rod 14 after being pushed up, thus realizing the unloading of the hoop original plate.

[0038] After the original plate of the hoop is cut, the second movable shaft 19 and the fourth movable shaft 29 move down along the first guide groove 20 and the second guide groove 30 respectively. The second movable shaft 19 and the fourth movable shaft 29 drive the first movable shaft 15 and the third movable shaft 27 to move down respectively, and drive the second push rod 14, the connecting rod 17 and the first push rod 13 to be put into the corresponding movable groove 16. At this time, the first push rod 13 and the second push rod 14 will not interfere with the rotation of the main carrier plate 6, and subsequent cutting operations can be carried out.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
