AI Technical Summary

Technical Problem

When drawing high-purity oxygen-free copper rods, the end of the copper rod furthest from the drawing device drops as it leaves the die, causing uneven stress on the end closest to the drawing device, which easily leads to deformation and affects processing quality.

Method used

A pulling device including a lifting mechanism is designed. The lifting mechanism consists of a base plate, an electric telescopic rod, a frame, a roller, and a connecting assembly. The electric telescopic rod drives the base plate to rise, so that the roller fits against the copper rod, intercepting and supporting the side of the copper rod away from the puller, and keeping the two ends of the copper rod balanced.

Benefits of technology

This effectively prevents the copper rod from falling away from the drawing tool and exerting force on the side closest to the drawing tool, reducing deformation, improving the processing quality and stability of the copper rod, and avoiding collisions between the copper rod and the machine body.
