Method and press apparatus for manufacturing

摘要

A method and apparatus for applying variable pressure to selected areas of a bonding assembly jig to shape a face plate to conform to the contours of contoured heads and hold the face plate in place for welding comprises two inverted U-shaped support frames including two spaced apart elongated vertical support members each having a bottom end and a top end, an elongated horizontal top beam extending between and connecting the top ends of the vertical support members, a track extending between and adjustably fastened to the horizontal top beam, and at least one hydraulic press slidably suspended from the track and adapted to apply pressure to a bonding assembly jig. The support frames are provided with wheels and one of the support frames has vertical support members spaced at a distance less that of the other support frame. This arrangement allows the tracks of each frame to be positioned proximate to each other above a bonding assembly jig.
