Wire collection device of wire electrical discharge machine

A wire collection device of a wire electrical discharge machine for collecting a used wire electrode having been used for electrical discharge machining and fed sequentially, comprising:

• a first collection box having a wire inlet provided at a top portion for introduction of the wire electrode;
• a second collection box having a wire inlet provided at a top portion for introduction of the wire electrode, 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 member 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 communicating with the wire inlet of the first collection box, and for making communication between the lower space and the upper space, wherein
• the wire collection device is configured in such a manner that, while the partition member is opened, the wire electrode is fed through the first collection box and the wire inlet of the second collection box into the second collection box and collected in the second collection box, and
• while the partition member is closed, the wire electrode is fed through the wire inlet of the first collection box, and accumulated and collected on the partition member.
