It enumerates common design errors, and includes case studies highlighting pitfalls in press work. Besides, it supplies indepth mathematical analysis supplemented by solved examples.
Types of press tools - Wikipedia
Considerable original material on pipes piercing is also included. Partings waste a certain amount of material, that can be significant. Trimming tool[ edit ] When cups and shells are drawn from flat sheet metal the edge is left wavy and irregular, press tool design theory to uneven flow of metal.
Shown is flanged shell, as well as the press tool design theory ring removed from around the edge. While a small amount of Material is removed from the side of a component in trimming tool. Trimming Tool Shaving tool[ edit ] Shaving removes a small amount of material around the edges press tool design theory a previously blanked stampings or piercing.
A straight, smooth edge is provided and therefore shaving is frequently performed on instrument parts, watch and clock parts and the like.

Shaving is accomplished in shaving tools especially designed for the purpose. Forming tool[ edit ] Forming is the operation of deforming a part in curved profile. Forming tools apply more complex forms to work pieces.
The line of bend is curved instead of straight and the metal is subjected to plastic flow or press tool design theory. Drawing tool[ edit ] Drawing tools transform flat sheets of metal into cups, shells or other drawn shapes by subjecting the material to severe plastic deformation.
Shown in fig is a rather deep shell that has been drawn from a flat sheet.

Drawing Tool This type of Press tool is used to perform only one particular operation therefore classified under stage tools.
Progressive tool[ edit ] A progressive tool differs from a stage press tool design theory in the following respect: At each stage the tool will progressively shape the component towards its final shape, with the final stage normally being cutting-off.
Compound tool[ edit ] The compound press tool design theory differs from progressive and stage tools by the arrangement of the punch and die.
