Wire straightening device and method for manufacturing wire

Abstract

A wire straightening device, including a straightening unit that performs straightening on a wire running in a longitudinal direction, an upstream measuring unit that measures a state of the wire at an upstream position from the straightening unit, and a controller that controls an operation of the straightening unit based on a measurement result of the upstream measuring unit, wherein the straightening unit includes a plurality of straightening rollers that contact the wire and perform straightening on the wire, an actuator that presses the straightening rollers toward the wire, and a load adjustment unit that adjusts a roller load applied from the actuator to the straightening rollers, and wherein the controller determines an open resistance pattern, which is a pattern of change in a roller load when the plurality of straightening rollers is pushed back by the wire, based on the measurement result of the upstream measuring unit.
