Edge folding process of large-radius arc metal curtain wallboard
The invention provides an edge folding process of a large-radius arc metal curtain wallboard, and relates to the technical field of metal curtain wall processing. The edge folding process comprises the steps that a rectangular flat plate is cut out in a plate shearing machine according to size requirements; the reserved edge folding portions of the two ends of the rectangular flat plate are grooved; the rectangular flat plate is fed into an arc edge folding machine to complete continuous arc edge folding, and rounding and edge folding of the flat plate are achieved at the same time; and the grooving lines are perpendicular to the height direction of the plate face, and the height between the grooving lines and the edge is the edge folding width. Compared with the prior art, folded edges and a front face decoration plate are integrated; compared with splicing and opening processes, product structural strength is guaranteed; in the edge folding process, folds are continuous and smooth, edge folding portions need no welding or grinding, and the continuity, strength and attractiveness of the overall structure are guaranteed; and meanwhile, the technological process is reduced, the production efficiency is improved, and the manual cost is reduced.
本发明提供了一种大半径圆弧金属幕墙板的折边工艺，涉及金属幕墙加工技术领域，包括根据尺寸要求在剪板机上裁剪出长方形平板；对长方形平板两端的预留折边部位进行开槽；送入圆弧折边机完成连续圆弧折边，实现平板同时弯圆和折边；其中开槽线与板面的高度方向垂直，开槽线离边缘的高度为折边的宽度。与现有技术相比，本发明折边与正面装饰板同为一体，相对拼装及开口工艺，保证了产品结构强度；该折边工艺折痕连续平滑，折边部位无需焊接、打磨，保证整体结构的连续性、强度和美观度，与此同时也减少了工艺流程，提高了生产效率，降低了人工成本。
