Aluminum Stretch Forming: Techniques, Considerations, and Analysis

Bending and roll bending, similar to stretch forming, are among the commonly used cold forming techniques for metal profiles. They exhibit characteristics of wide applicability and stable forming. Particularly suitable for bending thin-walled, square tubes, and single-radius profiled parts. Fabrication of multi-segment arc-shaped workpieces for bending can be complex. Let me elaborate on the bending of aluminum profiles!

Aluminum profile 3D stretch forming process

Since the motion trajectory of the clamping head in the three-dimensional stretch forming of aluminum profiles is generally curved, and the aluminum profile undergoes stretching deformation during the bending process, it is difficult to obtain the motion trajectory of the bending clamping head. Therefore, a method for determining the motion trajectory of the clamping head in the three-dimensional stretch forming of aluminum profiles is proposed.

Curvature Design Principles for Stretch Forming Workpieces

The key technology of the stretch bending forming process is that the arc design principle of the stretch bending workpiece is to not exceed the elongation rate of the material. During stretch forming, forming defects such as thinning of the profile wall thickness, fracture, wrinkling, and cross-sectional distortion will occur. These forming defects are related to Factors such as the mechanical properties, cross-sectional shape, and bending process parameters of the profile are closely related.

Stretch Forming Aluminum Extrusions

Stretch forming aluminum extrusions is a metal forming process used to shape and contour aluminum extrusions, typically for applications that require complex and curved shapes.

Stretch forming aluminum extrusions involves elongating or stretching an aluminum extrusion over a die or a form block, allowing the material to conform to the desired shape without causing significant thinning or material loss.
