Wire Electrode Feed Path Control Using a Diverted Fluid Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire electrode feeding systems often cause the wire electrode to deviate from its original path, leading to winding around rollers, despite attempts to suppress roller rotation, as the techniques fail to adequately prevent such deviations.
Innovation Solution
A wire electrode feeding apparatus that includes a fluid supply unit to supply a second fluid to a diverted flow path, reducing or stopping the transfer of the first fluid, and utilizing a roller to change the feeding direction, with the diverted flow path defined along the contact face of the roller not on the wire electrode path, and a discharging unit to discharge the first fluid toward the feeding outlet, creating a pressure difference to prevent deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the roller is rotated according to the supply of fluid to prevent wire electrode winding, then the wire electrode can be fed without winding around the roller, but the wire electrode deviates from its original path
Solution Approach 1:
The fluid flow path is divided into two separate paths: a main flow path that guides the wire electrode accurately, and a diverted flow path that supplies fluid to the roller for rotation control. This segmentation allows independent optimization of each function without interference.
Solution Approach 2:
A diverted flow path acts as an intermediary channel that redirects fluid away from the main wire electrode path. This intermediary structure enables the roller to receive sufficient fluid for rotation control while preventing fluid-induced deviation of the wire electrode from its original path.
2Device complexity
If the rotational operation of the roller is suppressed to reduce or stop rotation, then the wire electrode winding is prevented, but the wire electrode still winds around the roller in some cases
Solution Approach 1:
Fluid pressure is applied to the roller through the diverted flow path to control its rotation. By adjusting the fluid supply pressure and flow rate, the roller rotation can be precisely controlled to prevent wire electrode winding while maintaining feeding reliability.
Solution Approach 2:
The rotation speed and fluid supply parameters are dynamically adjusted based on feeding conditions. By changing parameters such as fluid pressure, flow rate, and roller rotation speed, the system adapts to different feeding scenarios to prevent wire electrode winding effectively.
3Manufacturing precision
If a diverted flow path is created to supply fluid to the roller, then the wire electrode path accuracy is maintained, but the system complexity increases
Solution Approach 1:
The fluid supply system serves multiple functions: it guides the wire electrode through the main flow path, controls roller rotation through the diverted flow path, and provides cooling/lubrication. This multi-functionality reduces the need for separate systems and minimizes overall device complexity.
Solution Approach 2:
The diverted flow path utilizes the spatial dimension by routing fluid along the contact face of the roller that is not on the wire electrode path. This three-dimensional arrangement allows independent fluid supply to the roller without interfering with the two-dimensional wire electrode feeding path.
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 apparatus effectively prevents the wire electrode from deviating from its original path by supplying a second fluid to the diverted flow path, reducing the flow of the first fluid and preventing winding around the roller, ensuring accurate feeding along the intended path.
Implementation Method 1
The pressure of the first fluid in the diverted flow path to which the second fluid is to be supplied by the fluid supply unit is lower than the pressure of the first fluid at a position from which the diverted flow path is diverted
Implementation Method 2
a roller configured to change the feeding direction of the wire electrode in a path of the wire electrode
Implementation Method 3
The pressure of the first fluid in the diverted flow path is due to discharging of the first fluid from the discharging unit toward the feeding outlet

AI summary
A wire electrode feeding apparatus or the like is provided, suitable for feeding a wire electrode along its original path without deviating from its original path. A conversion unit 9 feeds the wire electrode from a feeding inlet 21 to a feeding outlet 25 using a machining liquid. A roller 23 changes the feeding direction of the wire electrode. A discharging unit 27 discharges the machining liquid toward the feeding outlet 25 in a direction tangential to the contact face of the roller 23, to generate a flow of the machining liquid. On the other hand, a diverted flow path for the machining liquid is defined along the contact face of the roller 23 from the feeding outlet 25 side to the feeding inlet 21 side. An intake unit 29 takes in air according to the pressure of the machining liquid to supply the air to the diverted flow path.
