Punching and welding all-in-one machine for automobile bumpers

The invention discloses an automobile bumper stamping and welding all-in-one machine, and particularly relates to the technical field of automobile part machining, the automobile bumper stamping and welding all-in-one machine comprises a rack and an internal mechanism, the rack comprises a supporting plate, the supporting plate is integrally fixed at the bottom end in the rack, and the internal mechanism is arranged in the middle of the upper end of the supporting plate. According to the stamping and welding all-in-one machine for the automobile bumper, when a workpiece is installed on the supporting mold, the workpiece can be sucked by the vacuum suction cup, so that the supporting mold is moved to the first station for punching work through the transplanting motor, and then is moved to the second station for pre-pressing welding after punching is completed, and therefore the whole structure is integrated; the punching precision is improved, the service life is prolonged, and the defects that in the prior ar
