Abstract

The invention discloses a method for manufacturing metal composite plates by stirring friction, relating to a method for manufacturing metal composite plates. The invention solves the problems of uneven welding layer surface, complicated working procedure and narrow application range of the existing method for manufacturing metal composite plates. A metal shroud plate is arranged on the upper end surface of a metal substrate, and the metal shroud plate and the metal substrate are both fixed on a worktable; a stirring head is arranged on optional position of the upper surface of the metal shroud plate; the included angle between the stirring head and vertical direction is from 0 to 10 degrees, the stirring head penetrates through the metal shroud plate to embed the metal substrate at the rotation speed of 200 to 3000 revolutions per minute, the embedding speed of the stirring head is 1-5mm / min, and the embedding depth in the metal substrate is 0.1-100mm; when the stirring head reaches set embedding depth, the stirring head moves along horizontal direction at the speed of 10-1000mm / min until the metal substrate and the metal shroud plate are combined. The method of the invention has simple operation, low cost, and no contamination in the manufacturing process.

Description

technical field [0001] The invention relates to a method of manufacturing a metal composite panel. Background technique [0002] Modern industrial applications have higher and higher requirements for the comprehensive performance of metal sheets, and at the same time, production costs must be minimized. The metal composite panel reduces the production cost of the metal sheet to the greatest extent while satisfying the surface performance and the overall performance. Metal composite panels are generally composed of a cladding plate and a substrate. The cladding plate is a layer of metal sheet covering the substrate. It is mainly used to improve various surface properties of the composite panel, such as corrosion resistance and wear resistance. Metal composite panels are generally It combines the advantages of substrate materials and cladding materials while avoiding their disadvantages. At present, the methods of producing metal composite panels mainly include explosive wel...
