Composite metal sheet processing method

Abstract

The invention discloses a composite metal plate processing method. The method is characterized in a core layer, a surface layer and a ground layer are produced, and the method also comprises the following steps: 1, heating the surface face and the bottom face of the core layer with hot air; 2, conveying the surface layer and the ground layer toward the surface face and the bottom face of the heated core layer, allowing the bottom face of the surface layer to be close to or abut against the surface face of the core layer, and allowing the surface face of the ground layer to be close to or abutagainst the bottom face of the core layer; and 3, heating the bottom face of the surface layer and the surface face of the ground layer with hot air, arranging the surface layer, the core layer and the ground layer in a top, middle and bottom three-layer sequence, conveying the arranged layers into a pressurizing section, and respectively pressurizing the ground layer and the ground layer by the pressurizing section to make the heated ground layer bottom face laminated to the surface face of the core layer and the heated ground layer surface face laminated to the bottom face of the core layerin order to produce a composite metal plate. The composite metal plate processing method has the advantages of easiness in enforcement, high processing efficiency, avoiding of damages and even deformation of paint faces on the surface face of the surface layer and the bottom face of the ground layer due to heating and pressurizing, and effective improvement of the quality of the product.

Description

technical field [0001] The invention relates to a processing method for a composite plate, in particular to a processing method for a composite metal plate. Background technique [0002] At present, the composite metal plate generally includes a metal inner core layer, a surface layer and a bottom layer. During production, the above three layers are combined into one body by heating and pressing. The production method is as follows: the surface layer, the metal inner core layer and the bottom layer are pressed together The upper, middle and lower layers are arranged in three layers, and the above three layers are transported into the hot-pressing roller channel, and the hot-pressing roller heats and presses the passing surface layer and bottom layer, so that the three layers are bonded together to obtain the required composite metal plate. However, the above-mentioned traditional composite metal plate processing method has the following disadvantages: (1) Since the surface l...

Problems solved by technology

However, the above-mentioned traditional composite metal plate processing method has the following disadvantages: (1) Since the surface layer surface and the bottom surface of the bottom layer all have paint, the hot pressing roller heats and presses the surface layer and the bottom layer at the same time, so the heated surface layer The paint surface on the surface and the bottom surface (that is: the outer surface of the surface layer and the bottom layer in contact with the hot pressing roller) is easily damaged by pressure, or even deformed, which affects product quality and even causes scrap
