project on design of press tools pdf

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 cup for the oil filter 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.
