[0002] The car roof is the cover on the top of the car body and is part of the overall structure of the car body. With the rapid economic development, consumers' requirements for car quality are gradually increasing. The design with a skylight is conducive to ventilation, lighting, and visual effects in the car body, providing passengers with better comfort. Therefore, when the existing car roof is stamped and formed, the waste material in the skylight area of ​​the roof will be punched and trimmed to cut out the area for placing the skylight, and the roof frame of the skylight area after cutting will be reworked for shaping and flanging to make the skylight more secure after placement.
