What is the working principle of stamping die

The stamping die is also called a cold die, which uses the pressure of a stamping machine to act on the die to change the shape of the metal placed in the die. From the function of the mold, there are drawing dies, punching dies, bending dies, riveting dies, etc. The working principle of the drawing dies is to use convex and concave dies of the same shape to press the material through the pressing plate to process the metal materials according to the design needs. Various geometric three-dimensional products. There are many factors to be considered, such as the punch pressure, the stretch rate of the metal material, the complexity of the product geometry, the die holding force, and the die gap. Blanking dies include simple single punches and continuous dies with complex structures. The main considerations are the structural rationality of machine tool pressure, die blanking force, die discharge force, blanking gap and complex shapes. There are many types of bending dies, including punching angles, acute angles, obtuse angles, and complex geometric shapes.
