TABLE OF CONTENTS Having completed the introductory portion of our work, we must now come to an understanding not only of die design itself, but also of the procedures followed by die designers in organizing components of different shapes, sizes, and composition into the unified concept called a die.
First, it should be understood that a definite order of steps must be taken in originating any die design. Haphazard design methods waste time and they often result in inefficient press tools. Conversely, systematic procedures will provide:
Consistently good designs.
Speedy, effortless work.
Fewer erasures.
Improved appearance of drawings.
Stronger punch and die components.
This section illustrates the 14 steps required for designing a die to produce the sample part shown in Figure 1.2. Study this order of steps carefully; by following it closely, you can begin at once to design a die yourself. Then when you have completed your design, the results you have achieved will surprise and please you.
By appropriate substitutions, the same steps can be taken in the design of any die. For example, in designing a multiple-station progressive die, all die blocks would be laid out at Step 2 The Die Block. If a spring stripper must be employed because of the nature of the operation, it simply replaces the solid stripper at Step 10 The Stripper Plate.
In the top view, outlines of the strip as well as all holes or openings are drawn with thin, red phantom lines. In the front and side view, the strip thickness...
