.... Extrusion dies can be divided into simple ones used for solid and open shapes and those with welding chambers (porthole, spider, and bridge dies) for semihollow and hollow shapes. A die for an aluminum section must have the following characteristics: Accurate dimensions and product shape to avoid...

... and correction of hollow dies are rather difficult compared with solid dies. The future trend in design will be to develop systematic methods for calculating port size, bridge height, and depth of the welding chamber and the welding chamber (pocket) provided in the die cap. The size and shape of the bridge need...

... would be 630 feet. The shape ( Fig. 37 ) is that of an inverted catenary. (A catenary is the shape of a chain that dangles from two points at the same level.) No structure of this shape had ever been built. Perhaps Saarinen’s idea stemmed from the fact that the famous Ead’s Bridge, built in 1874...

... A schematic of a direct extrusion press is shown in Fig. 2 . Direct presses are used to make solid bars, rods, strips, and integrated sections. The presses can also be used to extrude tubes and hollow sections from softer grade aluminum using a solid billet through a porthole or bridge dies. A direct...

... ). To carry out a sheet metal forming operation, the press has to be able to accommodate the dies and generate the necessary motion (i.e., stroke). Therefore, it is important to have sufficient die space, bolster area, slide face area, and press shutheight. A specific forming operation (deep drawing, bending...
