Abstract

The invention discloses a method for manufacturing a metal composite panel. The manufacturing method includes the following steps: taking out the upper metal sheet and the lower metal sheet, cutting and blanking, and processing to obtain the upper sheet metal and the lower sheet metal with at least three bending edges. Sheet metal parts; bonding the PVC film suitable for the upper sheet metal part and the lower sheet metal part, folding the PVC film on the bending edge inward; evenly coating polyurethane adhesive, heating and rolling to form a composite Sheet metal parts; secondary bending and forming of composite sheet metal parts; drilling of bent parts with auxiliary processing parts; drilling holes in the auxiliary processing piece and the area to be drilled with a drill bit; The bent piece is cured and cured to obtain a metal composite panel. The metal composite board of the present invention guarantees excellent bonding strength and mechanical properties, is firm and stable, is smooth polished, is convenient to process, saves costs, is suitable for large-scale production, and can be widely used in building curtain walls, interior decoration, light industry manufacturing, furniture manufacturing, etc. field.

Description

technical field [0001] The invention relates to the technical field of metal plate processing, in particular to a method for manufacturing a metal composite plate. Background technique [0002] With the progress and development of society, the contradiction of shortage of various mineral resources is becoming more and more prominent, especially various precious metal resources. In this context, how to improve the utilization rate of metal resources is particularly important. In the architectural decoration industry and light manufacturing industry, there is a huge demand for various metal sheets, such as copper, stainless steel, titanium, titanium zinc, and aluminum. However, in the actual application process, the existing technology is mainly aimed at utilizing the surface material characteristics and thickness of the plate, which brings unlimited opportunities for the bimetallic composite plate manufacturing industry. By compounding the double metal layer, the characteri...
