Segmented Wire Delivery Support for Buckling-Free Coil Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire winding devices face issues with buckling of flat rectangular wires due to gaps between wire guides and increased device size when delivering larger amounts of wire, especially when using rectangular cross-section wires.
Innovation Solution
A wire rod delivering device with a fixed chuck device, movable chuck device, and actuator, featuring support parts arranged at predetermined intervals to prevent buckling and maintain device size, using elastic members like coil springs to evenly distribute support parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tubular wire rod guide with length greater than the delivered amount is provided on the movable chuck device, then buckling of the wire rod is prevented, but the device size is increased to at least twice as long as the delivered amount
Solution Approach 1:
The wire rod guide is divided into multiple sections corresponding to support parts arranged at predetermined intervals. Instead of using a single long tubular guide, the guide is segmented into shorter sections that can be positioned at intervals along the delivery path, reducing the overall device length while maintaining buckling prevention capability
Solution Approach 2:
Multiple support parts are introduced as intermediary elements between the movable and fixed chuck devices. These support parts provide intermediate support points for the wire rod during delivery, preventing buckling without requiring a single long guide structure
Applied Scientific Principles
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 effectively delivers flat rectangular wires without buckling, allowing for increased delivery amounts without enlarging the device, and supports various cross-sectional shapes like rectangular and round wires, enabling precise coil formation.
Implementation Method 1
arrangement means configured to arrange the plurality of support parts at predetermined intervals between the fixed chuck device and the movable chuck device
