Manufacturing methodof rear quarter window bright strip

Abstract

The invention belongs to the technical field of vehicular fittings and provides a rear quarter window bright strip and a manufacturing method thereof. The rear quarter window bright strip comprises a main body which is mainly integrated by a base plate at the left side and a bent part at the right side; the bent part is inclined to be bent relative to the base part; the cross section of the bent part is wider than that of the base part, and the cross section becomes wider gradually from the connection of the base part and the bent part to the bent part; and a bright strip is manufactured through the steps of extruding, bending, rib milling, milling and overhauling, blanking and trimming, punch forming, polishing, assembling, and the like. The invention has the advantages that the entire rear quarter window bright strip is integrally formed, the manufacturing method is simple, the yield and percent of pass are increased, the production cost is lowered, the surface of the manufactured bright strip is smooth, and the corrosion resistance is good; and the firmness is good after the rear quarter window bright strip is mounted on a vehicle body, the quality is reliable, and the externaloverall effect of an automobile is improved.
