[0002] Bumpers are installed at the front and rear ends of cars. They not only have decorative functions, but more importantly, they are safety devices that absorb and mitigate external impact forces, protect the car body and the safety of the occupants. In the process of making car bumpers, in order to ensure the beauty and functionality of the bumpers, it is necessary to use stamping and welding methods, so a stamping and welding integrated device is required.

[0003] When stamping a car bumper, the stamping device will inevitably vibrate. If the vibration cannot be mitigated or eliminated, some parts inside the car bumper stamping and welding machine may become loose or damaged, thereby reducing the service life of the car stamping and welding device. Utility Model Content

[0015] Preferably, a mounting frame is fixedly installed on the upper surface of the base plate closer to the front end, a first hydraulic rod is fixedly installed on the top of the mounting frame, an output end of the first hydraulic rod passes through the mounting frame, a punching head is fixedly installed on the output end of the first hydraulic rod, a lifting rod is fixedly installed on the upper surface of the base plate closer to the rear end, a cross plate is fixedly installed on the lifting end of the lifting rod, and a welding head is fixedly installed on the bottom of the cross plate.

[0016] By adopting the above technical solution, the placement plate is moved to the bottom of the mounting frame, and then the first hydraulic rod is controlled to drive the punching head installed at its output end to descend, so as to stamp the automobile bumper, and then the placement plate is moved to the welding position, and then the lifting rod is controlled to drive the cross plate installed at its lifting end to rise to the required height, and then when the welding head is aligned with the place where the bumper needs to be welded, the lifting rod is controlled to descend and contact the place where the bumper needs to be welded, so as to weld the bumper.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The integrated punching and welding device for automobile bumpers drives the sliding block to move outward on the connecting rod through the connecting plates installed in the connecting shafts on both sides of the buffer column. Then, when the sliding block moves outward on the connecting rod, the second buffer spring will reduce the vibration generated in the punching device when the automobile bumper is punched. At the same time, the first buffer spring between the connecting column and the buffer rod will also reduce the buffering force to a certain extent, so that the connecting column is inserted into the buffer rod, which effectively prevents the parts in the automobile bumper punching and welding device from being loosened or damaged when the bumper is punched and welded for many times.

[0019] 2. The integrated device for punching and welding automobile bumpers places the automobile bumper to be punched and welded on a placement plate, and then controls the push rods installed on the outer surfaces of the second vertical plates on both sides of the placement plate, so that the second push rods drive the clamping plates installed on the pushing ends thereof to fix the automobile bumper placed on the placement plate, thereby making the automobile bumper better punched and welded, and preventing shaking during punching and welding, which may cause unsatisfactory punching and welding effects.

[0028] Working principle: The structure on the bottom plate 1 is supported by the four supporting legs 2 installed at the bottom of the bottom plate 1, and then because the connecting block 6 installed at the bottom of the sliding plate 5 is connected to the threaded rod 4, when the driving motor 3 rotates, it will drive the threaded rod 4 installed on its output end to rotate, so that the sliding plate 5 can better drive the car bumper on the placement plate 18 to move, and then when the car bumper is stamped, the punching and welding device will generally produce some large vibrations, which may cause some parts inside the car bumper punching and welding device to loosen, then when the punching head 24 is stamping, it will generate a certain falling force, and then the buffer column 16 installed at the bottom of the placement plate 18 will drop, and then the connecting shaft 17 installed on both sides of the top of the buffer column 16 will drive the connecting plate 15 to move to both sides, and then because the end of the connecting plate 15 is connected to the sliding block 14, so when the connecting plate 15 moves to both sides When moving, the sliding block 14 will move to both sides of the connecting rod 11.
