摘要：To provide a wire electrode removal device of a wire electric discharge machine, the wire electrode removal device including a wire-electrode guide unit that guides an end on a cut point side of a wire electrode cut by wire-electrode cut devices to outside of a running path, a rewind shaft that pressure-fixes the wire electrode on the cut point side guided by the wire-electrode guide unit with an end face thereof and rewinds the wire electrode on a columnar member having angular portions with subsequent rotational driving thereof, a rewind-shaft drive unit that drives the rewind shaft to perform pressure fixing or pressure releasing of the wire electrode with the rewind shaft, a scraper member that removes a wound wire electrode from the columnar member at a time of pressure releasing of the rewind shaft by the rewind-shaft drive unit, and a collection member that collects the removed wire electrode.

主权项：1. A wire electric discharge machine comprising: a wire-electrode cutting unit that is placed on a running path of a wire electrode and configured to cut the wire electrode; and a removal unit configured to remove a wire electrode cut by the wire-electrode cutting unit from the running path, wherein the removal unit includes a wire-electrode guide unit configured to guide an end on a cut point side of the wire electrode cut by the wire-electrode cutting unit to outside of the running path, a rewind shaft comprising a member having angular sides and configured to press and fix the wire electrode on the cut point side guided by the wire-electrode guide unit with an end face of the rewind shaft, and rewind the wire electrode on the member with rotational driving, a rewind-shaft drive unit configured to drive the rewind shaft to perform pressing and fixing or releasing the pressing of the wire electrode by the rewind shaft, a scraper member through which the rewind shaft passes and configured to remove the wound wire electrode from the member when the rewind-shaft drive unit releases the pressing of the rewind shaft, and a collection member configured to collect the removed wire electrode.
