Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial machines for bending metal elements face challenges in aligning upper sheet-pressing tools on both the horizontal and vertical planes, particularly after initial folds, leading to incomplete folds and imperfect alignment.
Innovation Solution
The machine incorporates a longitudinal member with an inclined interface and modular, fractional sheet-pressing tools, coupled with hydraulic or pneumatic actuators and clamping screws, allowing for precise horizontal and vertical alignment through adjustable and removable elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the upper sheet-pressing tools are made extractable and repositionable to adapt to space constraints after initial folds, then the ability to perform additional folds on all sides is improved, but the alignment precision of the tools on horizontal and vertical planes deteriorates
Solution Approach 1:
The upper sheet-pressing tool is divided into multiple extractable and repositionable elements that can be independently adjusted. This segmentation allows the tool to adapt to different spatial constraints after initial folds while maintaining precise alignment through individual element positioning.
Solution Approach 2:
The sheet-pressing tool elements are designed to be dynamically reconfigurable, allowing extraction and repositioning based on the folding sequence and space availability. This dynamic capability enables the tool to maintain both adaptability to changing conditions and precision through controlled repositioning mechanisms.
2Adaptability or versatility
If the dimensions of upper sheet-pressing tools are reduced by eliminating central elements to fit in reduced space, then the ability to perform subsequent folds is improved, but the quality of clean and smooth folds deteriorates
Solution Approach 1:
The sheet-pressing tool is segmented into multiple elements where central elements can be selectively removed or retained. This allows the tool to reduce its effective dimensions to fit in reduced space while maintaining the integrity and quality of folds through the presence of necessary pressing elements at critical positions.
Solution Approach 2:
Different regions of the sheet-pressing tool have different functionalities - central elements are removed only where space constraints exist, while elements at positions critical for producing clean folds are retained. This local differentiation allows space adaptation without compromising fold quality in essential areas.

AI summary
A release device developed for an industrial machine for the bending of metal elements via a plurality of sheet-pressing tools arranged on a support frame is disclosed. The device includes a longitudinal member whereupon the sheet-pressing tools are positioned via an inclined interface. A modular coupling interface is included and situated between the wall of the machine and tightening elements, which keeps the tools locked in position. Clamping elements are set out which are suitable for locking the interface against the upper wall of the tools and which are arranged in an alternate manner in relation to a plurality of actuators. The actuators, once actuated, exert a force against the wall that is opposite to that exerted by clamping elements, and therefore allow for the horizontal displacement of the clamping elements, such a displacement making it possible for the interface to move itself vertically in such a way as to allow for the removal of the sheet-pressing tool.
