Edge rolling technology for large-sized covering component

The invention discloses an edge rolling technology for a large-sized covering component. The edge rolling technology for the large-sized covering component is mainly used for rolling an edge of the large-sized covering component, and comprises the following steps: 1), arranging convex ribs in a drawing process; 2), trimming the convex ribs; 3), flanging and shaping the convex ribs so as to achieve a pre-bending effect; and 4), rolling the edge. The edge rolling technology provided by the invention is realized by a mould; the rolled edge has a consistent specification; a high-efficiency production can be realized; and the problem that the working quality and the working efficiency caused by manual pre-bending of the covering component by an operator are relatively low can be solved.
