Abstract In this research, the deep drawing dies are designed by using a "computer - aided designed calculating system" to save time and facilitate the design process. Also finite elements method (F EM) is used to simulate the drawing process to select the best die design.
Drawing dies transform flat sheets of metal into cups, shells, or other drawn shapes by subjecting the material to severe plastic deformation. For instance, a rather deep shell has been drawn from a flat sheet, as shown in the illustration. In swaging operations, drawn shells or tubes are reduced in diameter for a portion of their lengths.
A die designer originates and designs dies employed to stamp and form parts from sheet metal, assemble parts together, and perform a variety of other operations. After a die has been designed on tracing paper, blueprints or ozalid prints are produced for use in the die shop where the dies are built.
To choose a suitable die set for a specific die design, you should: select a suitable die set and draw its views, as shown in Fig. 17·19 (9) and (10) . (cont.)
A representative die design is separated into fourteen distinct steps . Each step is illustrated in two ways: as a portion of an engineering drawing (i.e., as the component is actually drawn on the die drawing), and pictorially (to improve the student's visualization).
For a press with a depth of throat of 8 inches, the corresponding dimension for the die set should be at least V-t inch shallower. Ten design steps are necessary in selecting and applying the views of a die set for a specific die design.
