- DESIGN OF PROGRESSIVE DIES
Abstract
Before converting raw materials to a finished product we need an accurate design of the product
and also data required for manufacturing. If the design is not accurate then defects will occur in the
manufactured product; small mistakes in designing a product makes the manufactured product useless so
more amount time is allotted for designing a new product (or) for modifying the existed design.
In this work the use of a software namely Pro/E for designing a progressive die to manufacture
washer for the M 12 bolt has been incorporated. A progressive die is a multiple station die. In this work
authors have designed a progressive die which has two stages of operation. The former operation is
piercing and is followed by blanking. In both operations a finite volume of metal is removed from the sheet
metal.
If the final product happens to be removed portion then the operation is blanking, on other hand if
pierced sheet metal is the final product then the operation is piercing. Both the operations are performed
simultaneously in a single stroke of press, thus enabling the user to obtain the final product in a single
stroke. This design procedure can also be extended for manufacturing washers for M-series bolts by
modifying the punch and die plate dimensions.
