Abstract
A precursor detection devicedetects a precursor of a stick-slip phenomenon in a drawing machine. The precursor detection deviceincludes a load measurement sectionfor measuring a load applied to a plug support barin the drawing direction, a precursor detection sectionfor detecting a precursor of a stick-slip phenomenon based on a load measurement value measured by the load measurement section, and a control section. After drawing is started, a load applied to the plug support barin the drawing direction is measured by the load measurement sectionduring a predetermined period from a measurement start point to a measurement end point, and based on the measured load measurement values, a precursor of a stick-slip phenomenon is detected by the precursor detection section
