Wire Collection Device for Wire EDM Continuous Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire electrical discharge machines require the power supply to be turned off to safely collect used wire electrodes, disrupting machining operations and reducing production rates.
Innovation Solution
A wire collection device with a first and second collection box system, a partition member, and detection sensors that allow continuous collection of used wire electrodes during machining by partitioning the collection space and automatically managing the wire electrode accumulation and ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply is turned off to safely collect used wire electrodes, then operator safety is improved, but machining operations are interrupted and production rate decreases
Solution Approach 1:
The collection box is divided into multiple compartments (first collection box and second collection box) that can be independently accessed and emptied. This segmentation allows operators to collect wire electrodes from one compartment without shutting down the entire machining system, maintaining safety while preserving continuous operation capability.
Solution Approach 2:
The wire electrode collection and disposal function is extracted from the main machining system. The collection box with its access ports and partition members allows wire electrodes to be removed and disposed of separately from the active machining area, enabling safety measures without interrupting the power supply or machining operations.
2Quantity of substance
If the collection box is continuously filled with used wire electrodes, then collection capacity is improved, but access for removal and disposal becomes difficult
Solution Approach 1:
The collection box is segmented into multiple compartments (first collection box and second collection box) with separate access ports. This allows the system to maintain large total capacity while enabling selective access to individual compartments for efficient wire electrode removal without disrupting the entire collection system.
Solution Approach 2:
The second collection box is nested within the first collection box, creating a hierarchical structure. This nesting arrangement maximizes space utilization for storage capacity while the access port in the outer box allows easy removal of the inner box for disposal operations.

AI summary
To provide a wire collection device of a wire electrical discharge machine capable of collecting a used wire electrode even while a power supply for the wire electrical discharge machine is not turned off and even during electrical discharge machining. A wire collection device of a wire electrical discharge machine comprises: a first collection box having a wire inlet provided at a top portion; a second collection box having a wire inlet provided at a top portion, housed in the first collection box, and capable of being taken out to the outside through an access port formed in the first collection box; and a partition plate provided to be openable and closable for partitioning the interior of the first collection box into lower space for housing the second collection box and upper space, and for making communication between the lower space and the upper space.
