AI Technical Summary

Technical Problem

In the existing technology, the flange surface is not thoroughly cleaned of oil stains and impurities before entering the oil immersion tank, resulting in uneven adhesion of protective oil and unsatisfactory wetting effect.

Method used

A protective oil hoisting and immersion system was designed, including a suspended conveyor line, a cleaning device, a drying device, and an oil immersion device. Through the multi-stage guidance and dynamic swing mechanism on the suspended conveyor line, the disturbance ability of the cleaning medium is enhanced, realizing continuous lifting and lowering movements and horizontal reciprocating disturbances on the flange surface, thereby improving the thoroughness of cleaning.

Benefits of technology

It improves the cleanliness of the flange surface, ensures uniform adhesion of the protective oil, reduces localized gaps or insufficient thickness, and enhances the wetting effect.

Abstract

The application provides a protective oil lifting and soaking system and relates to the technical field of mechanical workpiece surface treatment. The system comprises a suspension conveying line, a cleaning device, a drying device and an oil soaking device. The suspension conveying line comprises a rack and a conveying guide rail, and the conveying guide rail is provided with a bearing surface on both sides. Multiple carriages are provided with rollers on the top for rolling lapping with the bearing surface and lifting lugs with lifting flanges on the bottom. The carriages are provided with abutting rods extending outward along the roller axis. The rack is provided with corrugated guide plates on both sides of the cleaning section, which have corrugated guide surfaces, and the two corrugated guide surfaces form a guide space. When the carriage enters the guide space, the end of the abutting rod abuts against the corrugated guide surface, drives the carriage to swing in the horizontal plane, and drives the flange to swing horizontally in the cleaning device. The application realizes automatic lifting of the flange by using the segmented guidance of the conveying guide rail, realizes horizontal swinging of the flange in the cleaning liquid by using the cooperation of the corrugated guide surface and the abutting rod, and realizes mechanical scouring of the surface of the flange and the inner wall of the hole and groove structure.
