Ziehstufe

Ziehstufe is a term that can refer to different concepts depending on the context, most commonly found in engineering and manufacturing. In a general sense, a Ziehstufe refers to a stage or step in a drawing process, particularly in metalworking. This process, known as deep drawing or simply drawing, involves deforming sheet metal into a hollow shape. Each Ziehstufe represents a specific reduction in diameter or an increase in depth of the workpiece as it moves through a series of dies. The overall drawing process is broken down into multiple Ziehstufe stages to achieve the desired final dimensions without causing the material to fracture or become excessively work-hardened.

In the context of wire drawing, a Ziehstufe also denotes a single pass through a die to reduce the diameter of a wire. Similar to deep drawing, wire drawing is often performed in multiple stages, with each Ziehstufe achieving a controlled reduction in the wire's cross-sectional area. The material properties and the geometry of the dies and lubricants are critical for successful drawing at each Ziehstufe.

The term Ziehstufe can also be encountered in other mechanical processes where a gradual reduction or shaping of material occurs through successive stages. The precise meaning is always derived from the specific industrial application or technical field where it is used.
