AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

The utility model relates to copper wire production technical field, concretely relates to a kind of copper wire production and processing's stretching device, including lubricating bucket and the conveying part for being immersed into the copper wire in lubricating bucket;Electromagnetic rod is located in lubricating bucket, it includes the sealing sleeve coaxially fixed in lubricating bucket and the electromagnetic coil coaxially located in sealing sleeve, for generating strong magnetic field and drive copper powder to the arc-shaped inner wall of lubricating bucket, fishing part is located in lubricating bucket, it includes the fishing ring coaxially slidingly located in lubricating bucket, the outer edge of the fishing ring contacts the inner wall of lubricating bucket.The utility model generates strong electromagnetic field by electromagnetic rod, since copper powder belongs to inverse magnetic material, it generates induced eddy current in alternating magnetic field, and then generates reverse magnetic field, forms repulsion with magnetic field source Lorentz magnetic force and is pushed to low magnetic field area by magnetic repulsion, copper powder can be pushed to the arc-shaped inner wall of lubricating bucket and gathered in real time, greatly extend the period of lubricating liquid cleaning or replacement, reduce its cleaning or replacement frequency.
