AI Technical Summary

Technical Problem

During the thread rolling process, screws adhere to a large amount of lubricant, which increases cleaning costs, and existing technologies make it difficult to efficiently recover and reuse the lubricant.

Method used

A screw thread processing line was designed, which uses a hydraulic rod to drive a moving thread rolling die to cooperate with a fixed thread rolling die. Combined with a delivery pump and a microfilter, the lubricant is recycled. The lubricant is sprayed and recovered during the thread rolling process, and impurities are filtered by the microfilter, forming a closed-loop circulation system.

Benefits of technology

This effectively reduces lubricant consumption, decreases the need for screw cleaning, lowers production costs, and improves production efficiency, thus achieving resource recycling of lubricant.
