AI Technical Summary

Technical Problem

The cutting of large bearing rings is difficult, especially the clamping and cutting of thick ring blanks, which brings about safety and convenience issues. Existing equipment is difficult to meet the requirements for safe and convenient cutting.

Method used

By using the upper and lower cooperation of auxiliary fixtures and blank holders, and through the horizontal rotation of the blank turntable and the feed cutting of the slitting tool, combined with the clamping of the lifting device and the hydraulic elastic clamp, the large-thickness cylindrical blank can be stably clamped and safely slitted. The auxiliary fixture can firmly grasp the semi-finished product after slitting.

Benefits of technology

It enables continuous slitting of large bearing ring semi-finished products, with stable clamping, simple operation, and high safety. It can complete the slitting operation safely and quickly, reducing the scrap rate.
