Abstract

The invention provides an outer panel piece and a formation method of the outer panel piece. The formation method of the outer panel piece comprises the steps that S1, a technology addendum face is pre-arranged on an outer panel piece to be stamped and formed; S2, a trimming line is pre-arranged on the technology addendum face; S3, a protrusion structure is formed on the technology addendum face through stamping. The formation method of the outer panel piece relieves the material lack tendency during drawing and flanging of the outer panel piece and protects the outer panel piece against deformation, rebound and even crack.

Description

technical field [0001] The invention relates to a stamping process of an automobile cover part, in particular to an outer plate part and a forming method thereof. Background technique [0002] Compared with other stamping parts, automotive panels, such as but not limited to fenders, engine compartment covers, and sunroofs, have complex shapes, thinner materials, more three-dimensional curved surfaces, and higher stamping surface quality. At the same time, the overlapping relationship between automobile panels and other stamping parts is also relatively complicated, and the product edges often need to be processed with arc-shaped contour lines with small curvature radius and large length. During the stamping and drawing operation of automobile panels, it is generally necessary to stretch and flang the plate. However, in the existing process, there is a partial shortage of material in the plate during the flanging process, and it is necessary to obtain material from the non-fl...
