AI Technical Summary
Existing copper wire stretching devices have difficulty effectively removing copper powder in lubricating fluid, which increases the risk of scratches and breakage on the copper wire surface. Frequent shutdowns for cleaning or changing the lubricating fluid also affect stretching efficiency.
A strong magnetic field is generated by an electromagnetic rod to drive copper powder toward the inner wall of the lubrication tank. Combined with the design of a retrieval ring and a filter ring groove, the copper powder is collected and cleaned in a concentrated manner through electromagnetic repulsion and the slowly rising and falling retrieval ring.
It extends the service life of the lubricant, reduces the frequency of cleaning and replacement, and improves the efficiency and stability of copper wire stretching.
