Book excerpt: Excerpt from Modern Blanking and Piercing Dies Punches and dies are made in such a variety of designs and for so many different purposes that it is difficult, if not impossible, to treat the subject of die construction and design in a general way and present fundamental principles which can be applied universally in the art of diemaking. For that reason, diemakers in describing their methods and practice have almost invariably confined their articles to specific die designs instead of attempting to deal with the theories of the subject. Contributions of this kind, relating to dies which have been in actual use, are, undoubtedly, of great practical value because they show what has been accomplished and often suggest a method or design that can be used for other classes of work. In this book various forms of blanking and piercing dies are illustrated and described. All of these designs are, of course, special in the sense that they are intended for producing some particular part, and, at first thought, it might seem useless to study the details of a die which, in all probability, will not exactly be duplicated within the experience of any one toolmaker or diemaker. It should be remembered, however, that the best way to obtain a broad, general knowledge of die construction is by studying as many different designs as possible, in order to become familiar with the constructional features which have proved successful in actual practice. Therefore, this treatise deals chiefly with various punch and die designs, and also the methods employed in connection with their construction. Incidentally, some of the tools illustrated represent ingenious types which are the development of long experience in the art of constructing dies. Examples of Modern Blanking and Piercing Dies Some interesting examples of die work taken from the diemaking department of the Taft-Peirce Manufacturing Co., Woonsocket, R. I., are shown in Figs. 1, 2, and 3. While the dies illustrated are used to produce comparatively plain parts, there are some points in their construction which may be of interest and value, particularly to those not experienced in the art of diemaking. The die shown in Fig. 1 is for producing the part illustrated at A in Fig. 4, which also shows the successive piercing, bending and blanking operations. The stock is fed through the die in the direction indicated by the arrow. On the first stroke the piercing operation at a is performed by punches of corresponding shape. On the next stroke a bending punch turns over the part b, making a right-angle bend, and, finally, the finished piece is blanked out.
