Fitting Bending Release Structure to Prevent Post-Bend Pinching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitting bending apparatuses often pinch between projecting portions of fittings after bending, making it difficult or impossible to release the fitting, leading to deformation, damage, and increased manufacturing costs.
Innovation Solution
A fitting bending apparatus with a pinching preventive function, featuring a fitting seating unit with an arcuate groove, a release unit with a fixing and releasing structure, a transport shaft, and an adjustment jig, allowing for easy detachment of the bent fitting by adjusting the fixing and releasing states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the fitting is fixed tightly in the bending apparatus to prevent movement during bending, then the bending precision is improved, but the fitting cannot be released after bending is completed
Solution Approach 1:
The release unit is designed to transition between a fixed state during bending and a released state after bending. The transport shaft moves the release unit along a predetermined path, dynamically changing its position from engaged with the fitting seating unit to detached, thereby resolving the contradiction between tight fixing during operation and easy release after operation
Solution Approach 2:
The release unit is preliminarily positioned to engage with the fitting seating unit before bending begins, ensuring proper fixation. After bending is completed, the transport shaft automatically moves the release unit away, providing preliminary preparation for the next bending operation without requiring manual intervention
2Stability of the object's composition
If the release unit remains fixed during bending to ensure stability, then the bending process is stable, but the release unit blocks the path for the bent fitting to be removed
Solution Approach 1:
The release unit dynamically changes its position along the transport shaft's path. During bending, it remains fixed in position to provide stability. After bending, it is transported away from the groove of the fitting seating unit, clearing the path for bent fitting removal while maintaining process stability during the actual bending operation
3Device complexity
If the fitting is held in place with a simple structure, then the device complexity is reduced, but the fitting may move during bending causing poor bending quality
Solution Approach 1:
The fixing mechanism is segmented into the release unit and the fitting seating unit. The release unit with its transport shaft provides automated positional control, while the fitting seating unit with its groove provides structural support. This segmentation allows for precise fitting fixation during bending while maintaining reasonable device complexity through modular design
