Wire Winding Nozzle With Adjustable Rod for Bulge Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional winding apparatuses fail to adjust the degree of wire reformation, leading to inconsistent wire bulging on magnetic poles with rectangular cross-sections, which complicates the winding process and reduces the number of turns on adjacent poles.
Innovation Solution
A winding apparatus with a supporting tool, a nozzle, a relative moving mechanism, a rod adjacent to the nozzle, and a rod rotating mechanism that allows the rod to follow the nozzle and adjust its position to reform the wire effectively, ensuring it is wound closely around the magnetic poles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If two pins are provided on both sides of a nozzle to reform the wire constantly, then wire lift and bulging are suppressed, but the degree of reformation cannot be adjusted, causing inconsistent winding quality across different layers
Solution Approach 1:
The pin is made movable relative to the nozzle, transitioning from a fixed position to a dynamically adjustable position. The pin can move in the radial direction of the wire feed hole, allowing the reformation degree to be changed according to different winding requirements and layers, thereby resolving the contradiction between maintaining wire alignment and enabling adaptability.
Solution Approach 2:
The position parameter of the pin is made variable. By changing the radial position of the pin relative to the wire feed hole, the degree of wire reformation can be adjusted. This parameter change allows the system to adapt to different winding layers and requirements while maintaining effective wire control.
2Device complexity
If the pin position is fixed relative to the nozzle, then the structure is simple, but the reformation strength cannot be adjusted for different layers
Solution Approach 1:
The pin is designed with movable capability relative to the nozzle, allowing it to transition from a static to a dynamic configuration. This dynamic design enables adjustment of the pin's radial position to control reformation strength for different layers.
Solution Approach 2:
The pin serves multiple functions: it can reform the wire with constant position for simple cases, and adjust its position to provide variable reformation degrees for complex multi-layer winding requirements. This multi-functionality reduces the need for multiple separate components.
3Manufacturing precision
If constant reformation is applied to the wire, then wire bulging is prevented, but the winding quality varies between first layer and last layer
Solution Approach 1:
The pin's position is made dynamically adjustable to adapt to different winding layers. By changing the radial position of the pin, the reformation degree can be optimized for each layer, ensuring consistent wire contact quality and winding stability across all layers.
Solution Approach 2:
The reformation parameter (pin position) is varied according to the winding layer and requirements. This parameter change allows the system to maintain optimal wire contact quality for each layer while ensuring overall winding consistency.
