AI Technical Summary

Technical Problem

In traditional copper tube drawing processing, the fixed size of the oil injection ring makes replacement cumbersome and costly, and it is difficult to adapt to the oil injection requirements of copper tubes of different diameters, resulting in oil waste and poor lubrication effect.

Method used

The spirally arranged oil spraying structure realizes the synchronous movement of the oil chamber through the slide groove, slider, telescopic rod and hinge, which can adapt to the oil spraying requirements of copper tubes with different diameters, and improves the oil spraying uniformity and coverage through the adjustable nozzle diameter and rotating oil spraying structure.

Benefits of technology

The universality and uniformity of the oil injection structure are achieved, the operation of replacing the oil injection ring is reduced, the cost is reduced, the waste of oil is avoided, and the lubrication effect of the copper tube is improved.

Abstract

The invention relates to the technical field of drawing machining, in particular to an oil injection structure for copper pipe drawing deformation machining, which comprises a barrel I for a copper pipe to pass through, a spiral groove formed in the inner wall of the barrel I, and a plurality of sliding blocks arranged in the spiral groove in a sliding manner, each sliding block is provided with a telescopic rod capable of stretching out and drawing back in the radial direction of the first barrel, and the end of each telescopic rod is provided with an oil chamber. A plurality of oil chambers are guided and limited through a spiral groove, a plurality of sliding blocks, a plurality of telescopic rods and a plurality of hinges, so that the oil chambers can be spirally arranged, and when the telescopic rods stretch out and draw back, the radius of a spiral where the oil chambers are located changes, and therefore the purpose of adjusting the distance between the oil chambers and one axis of a barrel is achieved; and the multiple oil chambers move synchronously, so that it is guaranteed that the distances between the multiple oil chambers and the outer wall of the copper pipe are consistent, nozzles in the oil chambers can conveniently conduct oil spraying treatment on the copper pipes with different diameters, and the applicability of the structure is improved.
