High-temperature drawing device for pure copper wire

The invention relates to the technical field of pure copper wire drawing, and provides a pure copper wire high-temperature drawing device, which is characterized in that a copper wire is subjected to heat treatment, so that the change of a microstructure in the copper wire is reduced, the dislocation movement is hindered by the increase of grain refinement grain boundaries, and an obvious work hardening phenomenon is generated; the copper wire drawing machine comprises a drawing machine body and a base, the bottom end of the drawing machine body is connected with the top end of the base, the top end of the base is fixedly connected with a bottom plate through a plurality of supporting columns, the top end of the bottom plate is fixedly connected with a top plate through two supporting plates, and the opposite ends of the two supporting plates are rotationally connected with gears; two connecting plates are arranged between the top plate and the bottom plate, sliding barrels are fixedly connected to the opposi
