stage tool, manufacturing process is press tool design. Two tools are to be designed i.e. Punching tool and. Bending tool. Punching tool is a progressive tool . 𝗣𝗗𝗙 | Press tools are commonly used in hydraulic, pneumatic, and The press tool will also be specified as a blanking tool, piercing tool, bending tool etc. . [1] Cyril Donaldson, George H LeCain, V C Goold, Tool design 3rd. PDF | On Jan 1, , Mr Anil Parmar and others published A Review on Process of Press Tool Design and its Manufacturing.

So a hardened stresses, stretching beyond the elastic limit.

Then the plate to prevent it from digging into the soft-top plate should Deformation, Penetration and Fracture will takes place. It is made out of case hardened tool steels.

D- Punch Plate- The punch is usually fixed to a plate with a light press fit. Punch holder holds all types of cutting and non-cutting punches to ensure alignment between punch and die it is made out of ST E- Punches- A punch is the male member of a press tool to get a component from the strip.

It is made out of good quality alloy steel. F- Stripper Plate- When cutting action is over, the punch withdraws from the die but the stock strip also will move Fig 1 Deformation Stage along with punch.

So for next operation strip cannot be moved forward. To facilitate this function one plate is fixed above the die plate.

This removes the strip from the punch is called stripper. It guides punches and pilots in this plate to ensure alignment with punch and die. G- Die Plate- A die block is defined as the block or plate from which the die profile is cut.

It is usually lower member of the tool. It provides cutting edge. The die opening has different designs and the design is selected after looking in the requirements and facilities available.

H- Bottom Plate- Bottom plate gives cushioning effect to Fig 2 Penetration Stage the die as well as provides enough space for the tool to be clamped to the press bed. There may be opening in the base plate, which allows the blank, or slug to fall and clear off from the tool.

The die assembly including stripper, all bottom elements are mounted on the bottom plate.

Pillar and bushes guide the moving and fixed half of the tool in the press and also it is used to ensure accurate alignment between the punches an. The material is stressed from punch Fig 3 Fracture Stage and dies side simultaneously in sections that lies parallel to the forces applied by means of shear blades or punches and 5.

The cutting action that occurs on blanking or piercing is that similar to that of chip formation by a cutting tool. The Material: The shearing or cutting forces Shear Force: The below figure shows the stress distribution of die under the applied loading condition. The orange and blue color in the plot indicates the maximum and minimum stress distribution respectively.

Punch and Die analysis is carried under computer aided engineering software to ensure that the design is safe. Punch and Die are the parts which undergo repeated loads in press tools, which is expensive too.

Computer aided engineering software it provides an opportunity to improve the design of the part prior to manufacturing.
