  • Patent number: 8959771
    Abstract: A method of manufacturing a shell from sheet metal for a room air conditioner/heat pump is shown. The sheet metal is stamped and formed to a U-shaped rectangular shell with open ends and a shell brace. Flanges on the outer edge of the U-shaped rectangular shell overlap at corners with (a) adjacent flanges or (b) the shell brace. Both the U-shaped rectangular shell and shell brace are inserted into an assembly machine where the corners are clinched and punched. The outermost flange at each corner is punched to a fixed diameter, but the innermost flange or the shell brace is only punched to a conical shape. Screws are inserted at each corner that pass through the fixed diameter to threadably engage only the conical shape of the innermost flange or shell brace.
