Description

Technical Field

[0001] This utility model relates to the field of anti-collision beam processing and manufacturing technology, and more specifically, to a high-strength steel anti-collision beam bending device. Background Technology

[0002] Anti-collision beams are structural components installed at the front, rear, or sides of a car. They are mainly used to absorb and disperse impact energy during a collision, protecting the vehicle body and the safety of its occupants. During the production process, anti-collision beams require bending equipment to bend the beam body.

[0003] Existing bending equipment can usually only bend one side of the beam installed on it. However, some anti-collision beams are structures that are bent on both sides. Therefore, when bending anti-collision beams, bending equipment is required to perform two bending operations on the beam, which makes the operation process inconvenient and the processing efficiency low. Utility Model Content

[0004] This invention provides a high-strength steel anti-collision beam bending device, which solves the technical problem that existing bending equipment can only bend one side of the beam installed on it, resulting in low processing efficiency of the anti-collision beam.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A high-strength steel anti-collision beam bending device includes a workbench with a bending module at the top. The bending module is located in the middle of the workbench and has arc-shaped edges on both sides. Two sets of rotating shafts are rotatably connected inside the workbench. Turntables are fixedly connected to the surfaces of the rotating shafts. A bending rod is provided on one side of the edge of the turntable. Two sets of arc-shaped grooves are also provided on the workbench outside the arc-shaped edge of the bending module. The top of the bending rod extends to the surface of the workbench through the arc-shaped grooves. A drive assembly for controlling the two sets of rotating shafts to rotate in opposite directions simultaneously is also provided inside the workbench.

[0007] Furthermore, the drive assembly includes a geared disc connected to two sets of rotating shafts, a first cylinder mounted on one side of the worktable, and a bidirectional rack disposed inside the worktable and connected to one end of the output shaft of the first cylinder. The bidirectional rack is located between the two sets of geared discs, and both sides of it mesh with the geared discs.

[0008] Furthermore, a roller is rotatably connected to the top end of the bending rod.

[0009] Furthermore, threaded sleeves are fixedly installed on both sides of the worktable, and screw rods are connected to the internal threads of the threaded sleeves. One end of the screw rod faces the outside of the worktable and is provided with a rotating handle, while the other end of the screw rod faces the inside of the worktable and is connected to a limiting plate. Scale lines are also provided on both sides of the worktable below the limiting plate.

[0010] Furthermore, a support is provided above the workbench, and a lighting lamp is installed on the support.

[0011] Furthermore, a second cylinder is fixedly installed on the workbench, and one end of the output shaft of the second cylinder is connected to a pressure plate, which is aligned with the middle of the bending module.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by placing the beam to be bent on the workbench, the beam can be aligned and abut against the middle position of the bending module. At this time, the two sets of bending rods extending from the workbench surface will abut against the two sides of the beam respectively. By controlling the two sets of bending rods to move in an arc shape at the same time through the drive component, the two sides of the beam attached to the bending module can be bent into shape in one go, making the operation process more convenient and effectively improving the processing efficiency of the anti-collision beam.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] 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 claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 A high-strength steel anti-collision beam bending device includes a workbench 1. A bending module 2 is installed at the top of the workbench 1. The bending module 2 is located in the middle of the workbench 1 and has arc-shaped structures on both sides. Its bending arc is equal to that of the two ends of the finished anti-collision beam. Two sets of rotating shafts 3 are rotatably connected inside the workbench 1. A turntable 4 is fixedly connected to the surface of the rotating shaft 3. A bending rod 5 is installed on one side of the edge of the turntable 4. Two sets of arc-shaped grooves 6 are also opened on the workbench 1. The two sets of arc-shaped grooves 6 are located on the outer side of the arc-shaped edge of the bending module 2. The top of the bending rod 5 extends to the surface of the workbench 1 through the arc-shaped groove 6. When the rotating shaft 3 rotates, the rotating shaft 3 will drive the turntable 4 to rotate. At this time, the bending rod 5 will move along the arc-shaped groove 6 under the drive of the turntable 4. A drive component is also installed inside the workbench 1. The drive component can generate opposite rotational driving force on the two sets of rotating shafts 3, thereby controlling the two sets of rotating shafts 3 to rotate in opposite directions at the same time.

[0022] During use, the beam to be bent is placed on the workbench 1, aligning it with the center of the bending module 2. At this point, the two sets of bending rods 5 extending from the workbench 1 will contact both sides of the beam. The drive assembly then generates opposing rotational forces on the two sets of rotating shafts 3, causing them to drive the two sets of turntables 4 to rotate outwards in opposite directions simultaneously. The turntables 4 then drive the bending rods 5 to move outwards in opposite arcs. During this process, the two sets of bending rods 5, contacting both sides of the beam, simultaneously bend both sides of the beam through their outward arc motion. When the two sets of bending rods 5 simultaneously reach both sides of the bending module 2... When the beam reaches the edge position, both sides of the beam will simultaneously bend and conform to the edges of the bending module 2 under the bending action of the two sets of bending rods 5. At this time, the two sets of rotating shafts 3 are controlled by the drive component to rotate in opposite directions, so that the two sets of bending rods 5 move inward in an arc and reset under the drive of the turntable 4. The formed anti-collision beam can then be removed from the workbench 1 for subsequent bending processing. Therefore, this device can control the two sets of bending rods 5 to move in an arc shape at the same time by the drive component. During this process, the two sides of the beam attached to the bending module 2 are bent and formed in one go, making the operation more convenient and effectively improving the processing efficiency of the anti-collision beam.

[0023] For further details, please refer to Figure 1-4 The drive assembly includes a geared disc 7 connected to two sets of rotating shafts 3, a first cylinder 8 mounted on one side of the worktable 1, and a bidirectional rack 9 located inside the worktable 1 and connected to one end of the output shaft of the first cylinder 8. The bidirectional rack 9 is located between the two sets of geared discs 7, and both sides of it mesh with the geared discs 7. The output shaft of the first cylinder 8 can drive the bidirectional rack 9 to move back and forth. During this process, the bidirectional rack 9 can drive the two sets of geared discs 7 meshing with it to rotate in opposite directions at the same time, thereby causing the two sets of rotating shafts 3 to be driven by opposite rotation at the same time.

[0024] For further details, please refer to Figure 1-4 The top of the bending rod 5 is rotatably connected to a roller 10. When the bending rod 5 bends the beam through an arc motion, the roller 10 at the top of the bending rod 5 will roll into contact with the surface of the beam, thereby reducing the contact friction between the bending rod 5 and the beam, avoiding wear on the beam surface, and further ensuring the forming quality of the anti-collision beam.

[0025] For further details, please refer to Figure 1-4The workbench 1 has screw sleeves 11 fixedly installed on both sides. The screw sleeves 11 are internally threaded with screw rods 12. One end of the screw rod 12 faces the outside of the workbench 1 and is provided with a handle 13. The other end of the screw rod 12 faces the inside of the workbench 1 and is connected to a limit plate 14. The workbench 1 has scale lines 15 located below the limit plate 14 on both sides. By holding the handle 13, the screw rod 12 can be rotated. During this process, the screw rod 12 will move horizontally under the drive of the screw sleeves 11, thereby controlling the horizontal position of the limit plate 14. The user can adjust the limit plates 14 on both sides of the workbench 1 according to the length of the beam and the scale lines 15 on the workbench 1, so that when the middle of the beam is aligned with the bending module 2, its two ends just touch the two sets of limit plates 14. This makes it easy for the user to accurately align beams of different lengths with the middle of the bending module 2 and accurately bend the two sides of the beam at equal intervals.

[0026] For further details, please refer to Figure 1-4 A support 16 is provided above the workbench 1, and a light 17 is installed on the support 16. The light 17 can provide illumination above the workbench 1, making it easier for users to operate even in dim surroundings.

[0027] For further details, please refer to Figure 1-4 A second cylinder 18 is fixedly installed on the workbench 1. One end of the output shaft of the second cylinder 18 is connected to a pressure plate 19. The pressure plate 19 is aligned with the middle of the bending module 2. During the bending process of the beam, the second cylinder 18 can be activated to drive the pressure plate 19 to press the beam into the middle of the bending module 2. This ensures that when the beam is subjected to bending on both sides, the middle part can remain in close contact with the bending module 2, thereby ensuring the stability of the beam and preventing displacement when subjected to force.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
