  • Method and system for manufacturing vehicle lid body
    Publication number: 20080072428
    Abstract: A to be-processed portion of an inner panel formed by stamping a steel plate is overlaid, in a thickness direction thereof, with a to-be-processed portion of a reinforcing member formed by stamping a steel plate. The inner panel and the reinforcing member are joined and integrated by a spot welding apparatus, thereby obtaining an intermediate article. A material handling robot puts off the intermediate article from the spot welding apparatus, conveys it to a pressing apparatus, and sets it against the pressing apparatus. The to-be-processed portion of the inner panel and the to-be-processed portion of the reinforcing member are subjected to piercing by the pressing apparatus.
