Sheet metal bending is, bar, pipebending and profiles some perspective and shape of the stamping process. This paper studies: The use of steel parts to establish the relationship between the characteristics of the Progressive Die layout design models, such as punching with layout design principles。 further steel ponents used in the shape of die structure design, create a model die, die design and technology Structural design, to determine the overall form of the mold。 Die in manufacturing, may be in the manufacturing and production process of debugging demonstrated the inadequacies and errors in design, through the speech summed up these problems, that can process design and die structure design, new or increased Technology rules, the die design for the future provide a valuable experience. Based on the above studies, the establishment of a viable, suitable for small steel parts stamping progressive die design and application in production.
