Post bending and edge covering structure of metal composite plate

Abstract

The invention discloses a post bending and edge covering forming process of a metal composite plate. The post bending and edge covering forming process of the metal composite plate specifically comprises the following forming process steps that firstly, a metal composite plate core layer is milled and removed by a milling cutter, and a groove seam is formed; secondly, the bending treatment processof burr edges of metal surface plates is performed, wherein due to the fact that the distance between the upper-layer metal surface plate and the lower-layer metal surface plate is relatively small,the metal surface layers are pre-bent by different angles for multiple times through a roller, and finally are bent to form 90 degrees; thirdly, the bending and edge covering treatment process of themetal surface plates is performed, wherein the metal surface plates with the burr edges bent in advance are pre-bent by different angle for multiple times through a mold along the surface of the metalcomposite plate core layer milled and removed in advance to form 90 degrees finally, the metal surface layers are used as covered edges, so that the perfect effect that the surface layers and a sidesurface are integrated is achieved, and falling off and cracking never occur; and according to the post bending and edge covering forming process, the whole piece of large plate is cut and then undergoes the bending forming technology, so that the forming speed is high, the size is random, a traditional mode of performing edge covering by adopting an edge cover strip is omitted, and labor and financial cost is greatly saved.

Description

technical field [0001] The invention relates to an edge-wrapping structure, in particular to a post-bending edge-wrapping structure of a metal composite plate. Background technique [0002] Disadvantages of the existing metal composite panels: for each size of the panel, the upper and lower metal panels need to be cut in advance, and then bent by a bending machine. Due to the non-uniform size, it will be higher after bending. For one part, automatic gluing machines cannot be used for gluing, but manual gluing can only be used, which is time-consuming and labor-intensive, and the molding speed is slow. Once the board is formed, the size cannot be changed, and the yield of the board is low.
