Title:
Wire rod softening device
Document Type and Number:
Japanese Patent JP6063134
Kind Code:
B2
Abstract:
The present invention provides a copper wire rod softening device which can stably soften a copper wire over a broad range from low speed area to high speed area. The copper wire (2) is guided to first, second and third electrode sheaves (31, 32, 33), and moved. A power supply (5) supplies AC voltage between the first and second electrode sheaves (31, 32), and between the second and third electrode sheaves (32, 33). Electrical current is applied to the copper wire (2), and thereby the copper wire (2) is softened. The power supply (5) consists of an inverter. The inverter has a converter portion transforming AC voltage into DC voltage, and an inverter portion transforming the DC voltage transformed by the converter portion into AC voltage.
