Biegeprozesse

Biegeprozesse, also known as bending processes, refer to a group of manufacturing operations where a material, typically sheet metal or wire, is plastically deformed to achieve a desired curved shape. This deformation is achieved by applying a force that exceeds the material's yield strength, causing it to bend and retain its new form after the force is removed. The primary goal of biegeprozesse is to alter the geometry of a workpiece without changing its overall mass or volume, though some minor thinning or thickening can occur in the bent region.

Common types of biegeprozesse include air bending, bottoming, and coining. Air bending involves pressing a punch into a die cavity with a specific angle, allowing the material to form around the punch without fully contacting the die walls. Bottoming presses the punch fully into the die, forcing the material to conform precisely to the die's shape. Coining utilizes high pressure to achieve very precise angles and sharp bends, often resulting in work hardening of the bent area.

The selection of a specific biegeprozess depends on factors such as the material's properties, the required bend radius, the desired accuracy, and the production volume. Tools and machinery such as press brakes, bending machines, and specialized dies are employed to execute these processes. Biegeprozesse are fundamental in many industries, including automotive, aerospace, and general manufacturing, for producing components like brackets, frames, housings, and structural elements.
