A flat rolling forming process with raised ribs

Abstract

The invention belongs to the technical field of rolling and particularly relates to a rolling forming process for a flat plate with a convex rib. The rolling forming process comprises two rolling stages, wherein in the first stage, a to-be-rolled plate is subjected to single-pass rolling or multiple-pass rolling to form a top-convex and bottom-concave plate with a convex rib on the upper surface and a concave structure on the lower surface; in the second stage, the lower surface of the top-convex and bottom-concave plate is subjected to single-pass rolling or multiple-pass rolling so as to beflattened, and a flat plate which has an upper surface with the convex rib and a flat lower surface is obtained. With the adoption of the process, the convex-rib type structure can be formed on the flat plate; in the plate rolling process, the convex rib can be accurately formed while a bottom plate is rolled to be flat; the problem that the convex rib is difficult to form on the premise that thebottom plate is flat in the rolling process of a special-shaped plate is solved.

Description

technical field [0001] The invention belongs to the technical field of rolling, in particular to a flat rolling forming process with raised ribs. Background technique [0002] Special-shaped plates are often used in the automotive industry, and their main features are to achieve lightweight vehicles, reduce costs, and improve production efficiency. Commonly used processing methods for special-shaped plates include welding, cutting, and rolling. In the above-mentioned processing methods, the rolling method produces less metal scrap, saves materials, improves the quality and performance of the plate, and is suitable for large-scale production. . [0003] Special-shaped plates need to be formed by multi-pass rolling. The similar rolling method is the rolling of longitudinal ribs. The rolling process of longitudinal ribs is combined with the forming process of strip and roll rolling. There are serious distortions in some parts, but they cannot be formed very quickly. Finely co...
