Abstract

The invention relates to the technical field of automobiles, in particular to a manufacturing method of a roof skylight. Comprising the following steps: OP10, drawing; oP20, trimming, flanging and punching are conducted through a trimming and shaping die; oP30, an idle station; the manipulator grabs the waste materials to an idle station, and the waste materials fall into a collecting box after the suction cup is deflated; oP40, flanging and shaping are carried out; straight flanging is conducted on the periphery of the top cover, the front air window is flanged to the depth of the flange edge, the rear air window is shaped in place, and straight flanging is completed on the side wall tailor-welded edge; oP50, side trimming, punching and side shaping are carried out; flanging and shaping the front air window clamping wedge in place, and trimming and punching the rear air window wedge; oP60, side flanging, side trimming and punching are carried out; and flanging the wedge of the side body tailor-welded edge, trimming the front windshield wedge, punching the rear windshield wedge, and punching shark fin mounting holes in the wedge. According to the manufacturing method, the workpiece manufacturing procedure is shortened, the production efficiency is improved, the workpiece material utilization rate is greatly improved, and the problems that the manufacturing cost is increased and the effective use area of material sheets is reduced in a traditional process are solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for manufacturing a roof sunroof. Background technique [0002] At present, the domestic auto market is becoming more and more diversified, and consumers have higher and higher requirements for ride comfort. Large sunroofs and panoramic sunroofs have gradually become the selling points of major OEMs. [0003] The large skylight or panoramic sunroof on the top cover has a large opening in the middle. How to reduce the mold cost under the premise of ensuring product quality has become an important research topic. Since the surface of the top cover A is an arc surface, after the skylight is trimmed, the waste material will rebound to a certain extent, and the waste material is easy to be stuck in the trimming die, and the waste material is difficult to discharge. [0004] The traditional process of manufacturing roof skylights is as follows: [0005] refer to figure ...
