Drug core wire reducing drawing machine

Abstract

This utility model provides a flux-cored welding wire diameter reduction drawing machine, relating to the technical field of welding material production equipment. It includes a flux core, a die body, and a grinding mechanism installed on one side of the outer wall of the die body for grinding the flux core surface. An adjustment mechanism is located at the front end of the grinding mechanism to drive the flux core to rotate. In this utility model, two grinding layers in the grinding mechanism contact the flux core surface. Under the rotation of two sets of annular plates, the grinding layers can generate friction with the outer wall of the flux core, effectively removing protrusions, burrs, and oxide scale from the flux core surface. Furthermore, the adjustment mechanism drives the flux core to rotate, creating a speed difference with the two synchronously rotating annular plates in the grinding mechanism. This speed difference causes the abrasive grains on the grinding layer surface to slide relative to the welding wire surface. Through sliding cutting action, the grinding effect is further improved, making the flux core surface smoother and reducing surface defects.
