Abstract
A method of manufacturing an assembly composed of two shaped and bonded parts in which the two parts to be shaped and bonded are placed on a header and die of a press, an adhesive is applied to at least one of the facing surfaces of the parts, the space between the header and the die is pressurized so that the parts are hot-formed to the shapes of the header and the die, and the header and die are then moved towards each other to press and bond the parts together.
Claims6
A method of manufacturing an assembly composed of two bonded parts, which comprises:
- providing a press having two members defining a header and a die which are movable towards and away from each other, at least one of said press members having cavities for shaping one of said parts;
- placing said two parts from which said assembly is to be formed on said press members, one part on said header and the other part on said die;
- placing a layer of adhesive on at least a portion of the surface of at least one of said two parts facing the other part;
- applying pressure between said head and said die such that said part on said at least one member having said cavities is deformed into said cavities to shape said part;
- and
- moving said header and said die towards each other to press said two parts against each other such that said parts are bonded together by said adhesive, wherein said applying of pressure comprises a superplastic forming operation and said parts comprise metal sheets which form a cowling.
