Integrated stretch-bending roof luggage rack for new energy automobile and forming process thereof

Abstract

The invention discloses an integrated stretch-bending roof luggage rack for the new energy automobile comprises. The rack comprises a luggage rack body, the luggage rack body is formed by machining analuminum alloy section bar, and the luggage rack body sequentially comprises a front supporting section, a main body rod section and a rear supporting section from front to back; the curvature of theluggage rack body is integrally formed through a three-dimensional stretch bending process, and the front supporting section of the luggage rack body is formed by machining the front end of a stretch-bent aluminum alloy section bar through a milling process. The rear supporting section of the luggage rack body is formed by processing the rear end of a bent aluminum alloy section bar through a milling process; an oxide film layer is formed on the outer surface of the luggage rack body; and a hole is formed in the bottom surface of the luggage rack main body rod section. The forming process ofthe integrated stretch-bending roof luggage rack of the new energy automobile comprises the steps of preparing an aluminum alloy section bar, stretch-bending the aluminum alloy section bar, sawing, milling, drilling, deburring, mechanically polishing, manually polishing and anodizing surface treatment.

Description

technical field [0001] The invention relates to the design and manufacturing technology of auto parts, in particular to a luggage rack installed on the roof of a car, in particular to a new energy vehicle integrated stretch-bending roof luggage rack and its forming process. Background technique [0002] The roof rack is a special device installed on the top of the vehicle for placing items. The roof luggage rack can carry a large amount of necessary items through the roof luggage rack when people are traveling, without occupying the space in the car. Roof racks usually consist of cross bars and support feet, one on the left and one on the roof. Most of the roof luggage racks in the prior art are composed of a plurality of components, so their structures are usually more complicated, and it is inconvenient to install and disassemble. Furthermore, because the roof rack is installed on the outside of the vehicle, it is prone to wear and corrosion under the conditions of peren...

AI Technical Summary

Problems solved by technology

Most of the roof racks in the prior art are composed of multiple components, so their structures are usually complicated and inconvenient to install and disassemble.

Furthermore, because the roof rack is installed on the outside of the vehicle, it is prone to wear and corrosion under the conditions of perennial use and sun and rain, thereby reducing the service life of the roof rack and the appearance of the vehicle. sex
