AI Technical Summary

Technical Problem

When existing hoisting equipment deals with aluminum alloy round ingots of different diameter specifications, the clamping stability is poor and easy to slip. The clamping force is too large and may cause scratches or indentations on the surface of the ingot, affecting the surface quality.

Method used

A lifting fixture including an annular shell and a plurality of movable clamp arms is designed. The clamping surface of the clamping arm is arc-shaped and is provided with a flexible anti-slip layer. The number of clamping components and the curvature of the clamping surface can be matched according to different specifications of the ingot to achieve more uniform stress and stable clamping.

Benefits of technology

The lifting fixture can better adapt to aluminum alloy round ingots of different diameter specifications, improve clamping stability and safety, reduce damage to the sides of the ingot, ensure surface quality, and reduce the scrap rate of subsequent material processing.
