Solution Overview

Problem

Existing roll-flanging tools face difficulties in efficiently flanging component parts with complex peripheral strips that have varying angular positions, leading to cumbersome tool movements and increased volume due to multiple flanging rollers and complex support structures.

Innovation Solution

A roll-flanging tool with a bearing structure that mounts two flanging rollers, each capable of rotation about distinct axes, and supported by a common spring, allowing for flexible positioning and reduced complexity by eliminating the need for multiple spring-elastic supports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple flanging rollers are used to flange peripheral strips with varying angular positions, then the tool can handle complex profiles, but the tool volume increases and the structure becomes more complex

Engineering Contradiction:
Improveability to flange complex peripheral stripsVSAvoidtool structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs a dynamically adjustable flanging roller system where the angle and position of rollers can be modified during operation. The bearing structure allows flanging rollers to be positioned at different angles relative to the peripheral strip, enabling adaptation to varying angular positions without requiring multiple fixed rollers. This dynamic adjustability resolves the contradiction by providing complex profile handling capability while maintaining a simpler, more compact tool structure.

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple spring-elastic supports are used for flanging rollers, then each roller is properly supported, but the tool volume and complexity increase

Engineering Contradiction:
Improveflanging roller supportVSAvoidsupport structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple spring-elastic support functions into a single integrated bearing structure. Instead of using separate spring supports for each flanging roller, the bearing structure provides a unified support system that accommodates multiple rollers while maintaining spring-elastic properties. This consolidation reduces the number of individual support components, thereby decreasing tool volume and structural complexity while preserving reliable support for all flanging rollers.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If the tool is designed to follow different angular positions of the peripheral strip, then flanging accuracy is maintained, but the tool becomes more cumbersome

Engineering Contradiction:
Improveflanging accuracyVSAvoidtool maneuverability
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent implements dynamic positioning mechanisms that allow the flanging roller to follow the angular variations of the peripheral strip without requiring the entire tool to be cumbersome. The bearing structure enables the roller to adjust its angular position independently, maintaining flanging accuracy on complex profiles while keeping the overall tool design more maneuverable and easier to operate.

AI summary

A roll-flanging tool, including a bearing structure having a connector, by which the tool can be connected via a connection plane to an actuator which can be moved spatially. A first arm and a second arm are spread apart from each other and connected to each other in a connection portion which includes the connector. A first flanging roller is mounted on an end of the first arm which faces away from the connection plane, such that it can be rotated about a first rotational axis which extends along the first arm and pierces the connection plane. A second flanging roller is mounted on an end of the second arm which faces away from the connection plane, such that it can be rotated about a second rotational axis. The first rotational axis intersects or crosses a perpendicular dropped onto the second rotational axis, in or on the roll-flanging tool.
