Adaptive Tool Design for Double-Sided Incremental Forming
Here’s PatSnap Eureka !
Summary
Problems
Conventional double-sided incremental forming tools face challenges in maintaining accurate contact with workpieces due to errors in simulation assumptions, machine stiffness variations, and mismatched sheet thickness, leading to reduced accuracy and damage during the forming process.
Innovation solutions
A forming tool design featuring a sleeve with a spring-biased contact member and bearing members that allow for rotational and translational movement, ensuring consistent contact with the workpiece by accommodating misalignment and stiffness variations, thereby maintaining the working tip in contact during the forming process.

Specific contradictions:
General conflict description:
Principle concept:
If conventional tools use rigid contact members, then structural simplicity is maintained, but contact accuracy is lost due to misalignment and stiffness variations
Why choose this principle:
The contact member is designed with dynamic capabilities through bearing members that enable rotational and translational movement. This allows the contact member to adapt its position and orientation during the forming process, maintaining accurate contact with the workpiece despite misalignment or stiffness variations, while avoiding the complexity of active control systems.
Principle concept:
If conventional tools use rigid contact members, then structural simplicity is maintained, but contact accuracy is lost due to misalignment and stiffness variations
Why choose this principle:
The tool enables changes in the contact member's positional parameters through the bearing members. The contact member can translate and rotate to adjust its location and orientation, compensating for alignment errors and maintaining precise contact with the workpiece surface throughout the forming process.

Abstract
A tool for use during double sided incremental forming of a workpiece. The tool includes a sleeve with a hollow interior space. A contact member is positioned within the hollow interior space of the sleeve. The contact member is sized with a working tip positioned outward beyond the sleeve to contact against a workpiece. A mount is positioned on the opposing end of the sleeve and configured to connect to a tool holder. The tool is configured to provide for translational and/or rotational movement of the contact member. The axial and rotational movement provides for the working tip to remain in contact with the workpiece during the forming process.
