AI Technical Summary

Technical Problem

Existing current collector forming fixtures are prone to oxidation and rust when using brass wire, leading to severe wear, uneven stress on the current collector, and potential breakage. Existing equipment cannot effectively solve this problem.

Method used

A current collector forming fixture was designed, comprising a wire drawing forming mechanism and a line optimization mechanism. Through components such as limiting rollers, electric hydraulic rods, rust-preventive oil spraying, and spreading rollers, rust removal and rust prevention treatment of brass wire is achieved, ensuring that a rust-preventive layer is formed on the surface of the current collector and improving the forming quality.

Benefits of technology

It effectively prevents the oxidation of brass wire, improves the forming effect and quality of the current collector, ensures the stability and consistency of the current collector, and reduces the risk of wear.

Abstract

This utility model belongs to the field of forming tooling technology, specifically relating to a current collector forming tooling, including a base, a wire drawing forming mechanism above the base, and a wire optimization mechanism on one side of the wire drawing forming mechanism. Through the wire optimization mechanism, when the wire passes through the first and second limiting rollers, an electric hydraulic rod is activated to move the copper wire support pad simultaneously, rubbing the surface of the brass wire to remove and straighten any small impurities adhering to the surface. When the current collector, after being cleaned and straightened, passes under the oil tank, booster pump, and rust-preventive oil spray nozzle, rust-preventive oil is sprayed onto the current collector, forming a new rust-preventive layer on its surface. This rust-preventive treatment before current collector collection ensures the current collector forming effect, increases the protection of the external surface of the current collector, improves the quality of the current collector, and is simple to operate and highly practical.
