Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision beam production, in particular to a front anti-collision beam stretching and bending device. Background Art

[0002] An automobile front anti-collision beam is a device used to absorb collision energy when the vehicle is collided. Its main function is to reduce the maintenance cost during medium and low-speed collisions and can, to a certain extent, reduce the harm to personnel. For example, a front anti-collision beam stretching and bending device with the authorization announcement number "CN220825346U" has a structure including an operating table for placing the front anti-collision beam; two bearing plates. A frame opening is provided at the upper end of the operating table, and a plurality of sliding rods are fixedly connected to the inner wall of the frame opening. The plurality of sliding rods are slidably connected to the side walls of the two bearing plates; a bending mechanism for stretching and bending the front anti-collision beam. The bending mechanism includes a first rod fixedly connected to the upper end of the bearing plate. A first wheel is sleeved on the side wall of the first rod. An arc-shaped through groove is provided on the side wall of the bearing plate close to the first rod. A second rod is rotatably connected to the lower end of the bearing plate, and a connecting plate is fixedly connected to the side wall of the second rod. The utility model can stretch and bend two symmetrical positions on the front anti-collision beam at one time, avoiding the need to measure the bending positions twice during the two-time bending process of the front anti-collision beam of an automobile in the prior art, which makes the operation cumbersome.

[0003] When the current front anti-collision beam stretching and bending device is in use, the two first motors are driven to rotate in opposite directions. Then, under the cooperation of the small gear and the large gear, the second rod drives the third rod to rotate through the connecting plate, and then drives the second wheel to rotate. At this time, the front anti-collision beam is located between the first wheel and the second wheel, and the rotation of the second wheel completes the stretching and bending of the front anti-collision beam, thereby completing the stretching and bending of two symmetrical positions on the front anti-collision beam at one time, avoiding stretching and bending one side of the front anti-collision beam of an automobile and then stretching and bending the other side in the prior art, making the operation more convenient.

[0004] During the use of the traditional anti-collision beam stretching and bending device, the raw material of the anti-collision beam to be processed is placed on the top of the stretching and bending device. After the staff manually adjusts the position of the workpiece, the stretching and bending device works while stretching and bending both sides of the anti-collision beam raw material. Since the anti-collision beam is not fixed during stretching and bending, it is easy to shift during the stretching and bending process, resulting in low processing accuracy of the anti-collision beam.

For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.

[0021] During the use of traditional anti-collision beam bending devices, the raw materials of the anti-collision beam to be processed are placed on the top of the bending device. After the staff manually adjusts the position of the workpiece, the bending device works while bending the two sides of the anti-collision beam raw material. Since the anti-collision beam is not fixed during bending, it is easy to deviate during the bending process, resulting in low processing accuracy of the anti-collision beam.

The raw materials of the anti-collision beam are placed above the main body of the bending device, and the fixing device fixes the raw materials of the anti-collision beam. After the raw materials of the anti-collision beam are fixed, they will not deviate during the bending process, thereby improving the processing accuracy of the anti-collision beam.

[0024] In the specific implementation process, it is particularly worth noting that the supporting legs 6 enhance the stability of the main body 1 of the bending device.

After adjustment by the adjusting device 3, the main body 1 of the bending device can bend anti-collision beams of different lengths. The bending device 4 can bend both sides of the anti-collision beam raw material simultaneously.

[0025] Specifically, when using this front anti-collision beam bending device, use the adjusting device 3 to adjust the position of the bending device 4.

Among them, rotating the first threaded rod 202 drives the clamping plate 203 to move, and the clamping plate 203 cooperates with the back plate 205 to fix the anti-collision beam.

[0027] In the specific implementation process, it is particularly worth noting that when the first threaded rod 202 rotates, it drives the clamping plate 203 to move, and the clamping plate 203 cooperates with the back plate 205 to fix the anti-collision beam raw material inside.

Among them, the second threaded rod 301 drives the pull rods 303 to move through the cross plate 302.

[0030] In the specific implementation process, it is particularly worth noting that twisting the second threaded rod 301 drives the cross plate 302 to move, and the cross plate 302 drives the pull rods 303 to move.

[0031] Specifically, on the basis of the above-mentioned first embodiment, the staff twists the second threaded rod 301 to rotate according to the length of the anti-collision beam raw material. The second threaded rod 301 drives the cross plate 302 to move, the cross plate 302 drives the pull rod 303 to move, and the pull rod 303 pulls a part of the structure of the bending device 4 to move inwards.

The arc groove 404 drives the circular plate 402 to rotate through the limiting rod 403, and the circular plate 402 drives the rotating rod 406 to rotate;

[0034] Furthermore, two circular rods 7 are installed on the outer walls of the two sliding plates 401, and two side plates 8 are installed on the outer walls of the two sliding plates 401;

[0035] In the specific implementation process, it is particularly pointed out that the circular rod 7 limits the anti-collision beam raw material, and the side plate 8 limits both sides of the anti-collision beam raw material, which is convenient for the fixing device 2 to fix the anti-collision beam raw material at the central position above the bending device main body 1;
