important in basic dies manufacturing and maintenance

This article aims to start a basic knowledge of the instrument of choice for beginners toolmakers, engineers and maintenance technicians to the press. First, define what is a stamping die and difference type of stamping dies exists in the market. Step by step, Die introduction and the component's of the function and application.
Basically the operation of stamping is a cold forming operation, A stamping die is usually consists of a serious of precision punches and dies that cuts and forms sheet metal into a desired shape or profile within a specified dimension zone. The die Component (punch and die) are typically made from special types of hardened tool steel. In some cases, die Componet are made of special material called carbide to prolong tool life and enable it to runs in much higher speed. ( 800- 1,500 spm in some cases)
Name of Die components:
1. Top Die shoe
2. Top thrust plate
3. Punch holder plate or punch plate
4. Punch
5. Stripper backing plate ( some tools without this plate)
6. Stripper plate
7. Die plate
8. Die backing plate
9. Lower Die shoe
10. Guide pillar and bush
Cutting operation Cutting operation is perhaps the most common operation performed in a stamping die. The component to be cut is placing in between the punch and die. Desired shape and form is cut after two members bypass each other. Usually, the Die is bigger than the punch to allow smooth enter of the punch. The sizes difference between the punch and die are called the cutting clearance.
Cutting clearances change with respect to the type of cutting operation being performed, the metal's properties, and the desired edge condition of the piece part. The cutting clearance often is expressed as a percentage of the metal's thickness. Different clearances applied to different material thickness and different type of material to be punched. The most common cutting clearance used is about 5 percent per side of the metal's thickness. In general, the harder the material the bigger the cutting clearance will be applied.
