AI Technical Summary
In the existing technology, when cold drawing brass alloys using wire EDM, lubricating oil is only applied once in the initial stage, resulting in insufficient lubricating oil during subsequent cold drawing processes, which affects the surface physical structure properties.
An oiling roller is installed above each guide roller, and lubricating oil is delivered through a fixed oil box and a movable oil box. Combined with an oiling brush, continuous oiling is performed above the pressure roller to ensure that the slow wire is continuously replenished with lubricating oil at multiple locations.
By continuously applying oil, the problem of insufficient lubrication is avoided, ensuring sufficient lubrication on the surface of the wire drawing machine and maintaining good physical structural properties.
