Flat Wire Oil Application Surfaces for Stable Bending Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil application devices struggle to accurately and stably apply oil to flat wires, leading to insufficient formation and increased frictional resistance between the wire and insulator, which can result in damaged insulators and poor dimensional accuracy of the formed segments.
Innovation Solution
An oil application device with a rotating mechanism that selectively applies oil to the first and second lateral surfaces of a flat wire using separate application surfaces, ensuring consistent oil supply even during wire vibration and preventing oil from being applied to non-target surfaces, thus maintaining accurate formation and reducing frictional resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If oil is applied to the entire surface of the flat wire, then frictional resistance is reduced, but the flat wire slips during bending process
Solution Approach 1:
The patent applies oil selectively to specific surfaces of the flat wire (first and second lateral surfaces) rather than the entire surface. The oil supply member includes first and second application surfaces that contact only the lateral surfaces, leaving the third surface (which contacts the die during bending) without oil. This local quality approach reduces frictional resistance where needed while preventing slippage during bending.
2Adaptability or versatility
If the application means moves along the U-shape, then oil can be applied to U-shaped objects, but the process becomes complex
Solution Approach 1:
The patent applies oil to the flat wire in its linear state before the bending process. The oil supply member is positioned to contact the lateral surfaces of the linear flat wire, applying oil in advance before the wire is bent into U-shape. This preliminary action simplifies the application process compared to moving the application means along the U-shape after bending.
3Productivity
If the flat wire is pulled out continuously, then productivity increases, but the wire vibrates due to tension changes
Solution Approach 1:
The patent employs a rotating oil supply member that dynamically adapts to the vibrating flat wire. The rotation mechanism allows the application surfaces to maintain contact with the lateral surfaces despite wire vibration caused by continuous pulling. This dynamic adjustment ensures stable oil application while maintaining high productivity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enables precise and stable oil application to flat wires, improving the accuracy of segment formation, reducing frictional resistance, and preventing insulator damage, resulting in high-yield segments with excellent dimensional accuracy.
Implementation Method 1
the frictional resistance between the insulator and the conductive wire increases... oil is applied to the conductive wire before being wound around the tooth portion. The oil serves as a lubricant.

AI summary
An oil application device includes an oil supply member capable of selectively supplying oil to a first lateral surface and a second lateral surface of a flat wire. The oil supply member includes a first side surface and a second side surface. A part of the first side surface is a first application surface that is in contact with a part of the first lateral surface. Another part of the first side surface is a first non-application surface spaced apart from the first lateral surface. A part of the second side surface is a second application surface that is in contact with a part of the second lateral surface. Another part of the second side surface is a second non-application surface spaced apart from the second lateral surface.
