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 niribopaca.ml Press Tool.
Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste.
It is a metal cutting operation. In blanking metal obtained after cutting is not a scrap or it is usable. The size of the blank depends on the size of the die.
So the size of the die opening is equal to the blank size. Clearance is given to the punch. Piercing tool[ edit ] Piercing tool Piercing involves cutting of clean holes with a resulting scrap slug.
The operation is called die cutting and can also produce flat components where the die, the shaped tool, is pressed into a sheet material employing a shearing action to cut holes. This method can be used to cut parts of different sizes and shapes in sheet metal, leather and many other materials.
Cut off tool[ edit ] Cutoff tool it is a shearing operation in which blanks are sperated from a sheet metal. Parting off tool[ edit ] are similar, in that a discrete part is cut from a sheet or strip of metal along a desired geometric path. The difference between a cutoff and a parting is that a cutoff can be nestled perfectly on the sheet metal, due to its geometry.
Summit Tool Design specializes in Progressive Dies
With cutoffs, the cutting of sheet metal can be done over one path at a time and there is practically no waste of material. 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.
Design of Press tools
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.
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. Punch Holder: This plate is used to accommodate the punches of press tool. Die Plate: Die plate will have similar profile of the component where cutting dies usually have holes with land and angular clearance and non cutting dies will have profiles.
Die Back Plate:This plate prevents the hardened Die inserts penetrating into bottom plate. A viewable 3D PDF file of the project. Printable 3D views and pages of the design.
downloadd items are also listed with part numbers, including the name of the supplier. Components, like bolts, dowels, etc.
Special pages included when applicable such as partial and or total weight of the project, over all dimensions, strip width, progression, etc. The tool room or machine shop may have additional information that could possibly be put on a CAD drawing.
The web based pages include images to fully explain what and how the project is intended to be done.
Your input may also be included in the pages. It is a visual and verbal extension of the CAD drawing of its part and or the assemblies.
The sample part drawing has many different holes that the CNC programmer will have difficulties identifying from the drawing. The additional web page has images with colour coded holes to visually identify all holes.Clearance is given to the punch.

So the size of the die opening is equal to the blank size. Generally 10mm screws are used on die components up to mm2.
With partings, the shape can not be nestled precisely. Dowel should be located diagonally across from each other and as apart as possible to increase the locational accuracy.
