Metal pipe fitting processing lubricating oil

Abstract

Disclosed metal pipe fitting processing lubricating oil is prepared from the following raw materials in parts by weight: 12-20 parts of nonylphenolpolyethoxylate, 10-15 parts of corn oil, 2-6 parts of sodium dodecyl sulfate, 2-5 parts of triethanolamine, 3-7 parts of sodium metaborate and 3-7 parts of urea. Compared with conventional lubricating oil, the metal pipe fitting processing lubricating oil has thixotropy, can be transformed from a paste into a liquid when conveyed to a to-be processed pipe fitting by an air powered pump or being stirred, is easy to convey and use, and helps to save the usage amount; the metal pipe fitting processing lubricating oil has extremely strong permeability and is easy to clean; the metal pipe fitting processing lubricating oil has extremely good lubricity, heat-transfer cooling performance, stability, rheological property and extreme pressure resistance; and the metal pipe fitting processing lubricating oil helps to furthest reduce cutting temperature and cutting force for processing metal pipe fittings, improve processing efficiency and precision, reduce workpiece roughness and improve surface quality.

Description

technical field [0001] The invention relates to a lubricating oil for processing metal pipe fittings, which belongs to the field of industrial chemical industry. Background technique [0002] Tapping is a basic operation skill of a fitter. Since the tapping cone needs to cut the internal thread in the working bottom hole during tapping, the cutting difficulty is more difficult than machining the external thread. The tapping head used in the tapping operation is in contact with the workpiece. It will produce a lot of friction and high temperature. In production practice, there are often thread rotten teeth, tapping head chipped teeth, and broken cones, which affect the quality of processed parts and even the entire product. Factors affecting the tapping effect include not only the material of the tapping cone, thermal effect, the diameter of the bottom hole of the thread, and the operating factors of the tapping cone, but also the geometry and angle of the tapping cone, the g...
