A stamping tool, often called a press tool, is a specially designed die set used to cut, form, or shape sheet metal into precise parts using a press machine. In the motor industry, especially in lamination punching, this tool plays a crucial role in producing high-accuracy components like rotor and stator laminations. The tool itself is typically made up of two main parts — a punch and a die. The punch is mounted on the top half of the press (called the ram), and the die is fixed on the bottom. When the press comes down, the punch pushes the sheet metal into the die cavity, cutting or forming the part.
Key Components of a Stamping Tool:
Punch – The cutting or forming element that moves downward into the die to shape the metal.
Die – The fixed base that holds the metal in place and provides the negative shape of the part.
Stripper Plate – Helps remove the metal part from the punch after each stroke.
Guide Pillars and Bushes – Ensure accurate alignment of the punch and die for consistent results.
Pilots (in progressive tools) – Help position the strip accurately at each stage of the punching process.
