Description

Technical Field

[0001] The utility model relates to the technical field of automobile part processing equipment, in particular to a bending device for an automobile bumper. Background Technique

[0002] An automobile bumper is a safety device installed at the front and rear of an automobile. When a vehicle collides, it absorbs and alleviates the external impact force, thereby protecting the safety of the vehicle body and the passengers in the vehicle.

[0003] The bumper is generally made of high-strength metal materials and covered with plastic on the outside to reduce damage during collisions. At the same time, in order to enable the bumper to better absorb and disperse the impact force when suffering a side impact, during the processing of the bumper, both ends of the bumper will be subjected to a bending operation through a bending device. For example, the Chinese utility model patent disclosed in the publication number CN219724211U: An automobile bumper bending machine. In this application, the electric push rod is started to clamp the automobile bumper, and thus the purpose of automatically fixing the automobile bumper is achieved. By starting the first servo motor, the output shaft of the first servo motor drives the bending wheel to rotate, driving the connecting plate and the electric push rod to rotate, thereby achieving the automatic bending of the automobile bumper. However, when bending the bumper, this application can only bend one end of the bumper during the bending operation, and this application also moves the bumper through two feeding wheels and a second servo motor, so the above structure limits the size of the bent bumper and cannot realize the quick picking and placing of the bumper.

By providing the adjustment shaft 6 with left-handed thread and right-handed thread sections, the two equipment boxes 7 can be synchronously driven to move relatively or in the opposite direction on the frame 1, so as to adjust the distance between the two equipment boxes 7;

[0023] As Figures 1-2 , Figure 4 As shown in the figure, two first fixed shafts 22 are fixedly installed inside the equipment box 7. Second chutes 25 are provided at the front end face and the rear end of the equipment box 7. Second sliders 24 are inserted and installed in the second chutes 25. A second fixed shaft 23 is fixedly installed between the two second sliders 24. The supporting wheel 8 and the limiting wheel 9 are respectively rotatably installed at one end of the corresponding first fixed shaft 22. The bending wheel 10 is rotatably installed at one end of the second fixed shaft 23. A hydraulic cylinder 4 is fixedly installed at the lower end of the equipment box 7. The output end of the hydraulic cylinder 4 is fixedly installed at the lower ends of the two second sliders 24 through a connecting block. By providing the supporting wheel 8, the limiting wheel 9 and the bendable and liftable bending wheel 10, the bending process of one end of the guard bar can be quickly carried out.

Then, the two second sliders 24 cooperate with the second fixed shaft 23 to move the bending wheel 10 upward, so that the bending wheel 10 can jack up one end of the automobile bumper. Thus, the two ends of the automobile bumper are bent with the corresponding limiting wheels 9 as the fulcrums. Subsequently, the output end of the hydraulic cylinder 4 moves the second slider 24 downward, thereby driving the second fixed shaft 23 and the bending wheel 10 to move downward and reset, and the bent bumper can be taken off;

[0025] When it is necessary to adjust the distance between the two equipment boxes 7 according to the length of the automobile bumper, the handwheel 15 at one end of the adjusting shaft 6 can be rotated. Then, the left-handed thread section and the right-handed thread section on the outer side of the adjusting shaft 6 respectively rotate in the internal thread pipes 20 on the upper end faces of the corresponding equipment boxes 7, so that the two equipment boxes 7 can move relatively or oppositely on the two guide rails 11 through the first sliders 18 at the lower ends respectively, thereby adjusting the processing distance between the two equipment boxes 7.
