Stamping die classification

There are many kinds of stamping dies. The stamping dies are classified according to their working properties, die structure and die materials.

 

Classification according to process properties

 

A. Dies for separating materials along closed or open contours. Such as blanking die, trimming die, cutting die, etc.

 

B. The bending die makes the blank or other blank bend along a straight line (bending line), so as to obtain a certain angle and shape of the workpiece die.

 

C. Drawing dies are dies that make blanks into open hollow parts or make hollow parts change shape and size further.

 

D. Forming die is a die which directly copies the shape of the convex and concave die of the blank or semi-finished product according to the figure, while the material itself only produces local plastic deformation.

 

 

 

 

A. The single-process die only completes one stamping process in one stroke of the press.

 

B. The compound die has only one working station. In one stroke of the press, two or more stamping processes are completed simultaneously at the same working station.

 

C. The progressive die (also known as continuous die) has two or more positions in the direction of blank feeding. During one stroke of the press, two or more stamping processes are completed at different positions one by one.

 

D. The transfer die integrates the characteristics of single-process die and progressive die. By using the transfer system of manipulator, the product can be transferred quickly in the die. It can greatly improve the production efficiency of the product, reduce the production cost of the product, save the cost of materials, and the quality is stable and reliable.
