Compound die generally consist of blanking and piercing operation which are performed in single press stroke. This design tool is. This book can be used for Board Examination by the Diploma in Mechanical Engineering (Tool & Die) students for the Tool Design subject. 2. The Use of this . This book is offered to: Students all over the world From Prof. Asad and Prof. Maz IUST Iran. Documents Similar To presinescinmett.tk Press Tool.

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 deformation. 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.

It is an axial elongation through the application of axial force. 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 tool in the following respect: in a progressive tool the final component is obtained by progressing the sheet metal or strip in more than one stage.

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 tool differs from progressive and stage tools by the arrangement of the punch and die. It is an inverted tool where blanking and piercing takes place in a single stage and also the blanking punch will act as the piercing die.

Combination tool[ edit ] In a combination tool two or more operations such as bending and trimming will be performed simultaneously. Two or more operations such as forming, drawing, extruding, embossing may be combined on the component with various cutting operations like blanking, piercing, broaching and cut off takes place- it can perform a cutting and non cutting operations in a single tool.

Design of Press tools

General press tool construction[ edit ] The general press tool construction will have following elements:- Shank: It is used to locate the press tool in press for alignment purpose. Top Plate: It is used to hold top half of the press tool with press slide. Cross reference files in seconds.

On this example, there is a plate with a number of different holes, like dowel holes, tapped and counter bored holes, etc. To keep the drawing clutter free yet provide enough information is not always possible.

The larger the work piece and or more holes to be processed, mistakes can be easily made. The machinist can scan the code with a smart phone and have an instant answer of the ongoing questions about the types of holes to be made.

MasterCam does not recognize the tapped holes as a feature, therefore this visual aid is found invaluable. The designer can have additional images, notes, etc. Once scanned, the web page automatically opens to view.

Remove sharp edges and corners of the plate.

All dowel holes to be slip fit gentle tap with a hammer. Before installation of the guide bushings, make sure that the four holes are cleaned well.

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 of 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 deformation. 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.

Before installation of the guide bushings, make sure that the four holes are cleaned well. Combination tool[ edit ] In a combination tool two or more operations such as bending and trimming will be performed simultaneously. Table 8. Using the same principle, die shut height for stamping dies, bendingdies, and formingdies can also be calculated. Navtej Singh. Dowels are subjected to shear stress due to horizontal force resulting from die clearance.

It is an axial elongation through the application of axial force. X area of cross section of punch 7.

With partings, the shape can not be nestled precisely.
