Abstract

The invention relates to the field of automobile part and component manufacturing technologies, in particular to an automobile wheel fender and a cold stamping forming technology of the automobile wheel fender. The wheel fender at least comprises a wheel fender body and reinforcement ribs located on the inner wall of the wheel fender body. The wheel fender body comprises a wheel fender upper portion and a wheel fender lower portion, multiple curve-shaped edges are arranged on the wheel fender body and comprise the edges matched with a front pillar of the side wall of an automobile body, the edges matched with an A pillar of the automobile body, the edges matched with an engine cover and the edges matched with a front bumper. Positioning installation holes are further formed in the wheel fender lower portion and the edges matched with front combination lamps. A special-shaped hole is further formed in the wheel fender body. The automobile wheel fender formed in a cold stamping mode is not prone to cracking in the use process, small in influence caused by outside temperature, long in service life, simple in technology and low in cost.

Description

technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an automobile fender and its cold stamping forming process. Background technique [0002] The fender is the outer panel of the car body that covers the wheels. It is named because the shape and position of the part of the old car body resemble a bird's wing. The installation position of the fender is divided into the front fender and the rear fender. The front fender is installed At the front wheels, the rear fenders are mounted at the rear wheels. [0003] The fender body in the prior art is an integral structure of integral injection molding. Although the fender of the engineering plastic structure does not deform much under the impact of a certain load, it is affected by the external environment, such as in winter, or by external forces. Under the action of impact, the fender with plastic structure is relatively brittle, and it is easy to crack under a ...
