The invention discloses an automatic punching welding method for a front bumper of an automobile. The automatic punching welding method comprises the following steps of S1, moving the bumper to a punching device; S2, first, compressing the bumper by a positioning block and a leaning block in the punching device, and then punching the bumper; S3, after the bumper is punched, moving the bumper to awelding room, and welding the bumper by welding equipment after an inert gas spraying device fills the welding room fully with inert gas. As the positioning block is mounted on a punching air cylinderand the leaning block matched with the positioning block is arranged on the other side of the bumper, the positioning block and the leaning block are provided with communicating holes matched with apunch, and the punch punches the bumper by means of the communicating holes and compresses the bumper by means of the positioning block and the leaning block, a condition that the bumper cracks when the bumper is punched is avoided, so that the punching and processing quality of the bumper are improved and the attractiveness of the bumper is improved.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to an automatic punching and welding method for an automobile front bumper. Background technique [0002] The car bumper is a safety device that absorbs and slows down the external impact and protects the front and rear of the car body. Many years ago, the front and rear bumpers of the car were stamped with steel plates into channel steel, riveted or welded with the frame longitudinal beam, and have a section with the car body. A large gap looks very unattractive. With the development of the automobile industry and the extensive application of engineering plastics in the automobile industry, automobile bumpers, as an important safety device, are also on the road to innovation. Today's car front and rear bumpers In addition to maintaining the original protection function, it is also necessary to pursue harmony and unity with the shape of the car body, and to pursue its own lightweight. The...
