Metal pipe processing lubricant

Abstract

The invention discloses a metal pipe processing lubricant, which is prepared from the following raw materials by weight: 12-20 parts of rapeseed oil, 10-15 parts of corn oil, 2-6 parts of sodium alkyl benzene sulfonate, 2-5 parts of triethanolamine, 3-7 parts of sodium borate and 3-7 parts of urea. Compared with the lubricant of the prior art, the lubricant provided by the invention has thixotropy, can convert from a paste to a liquid when being transported to a workpiece by a pneumatic pump and stirred, is easy to transport and use and saves the dosage. The lubricant provided by the invention has the advantages of strong permeability, easiness for cleaning, good lubricating performance, heat transfer cooling performance, stability, rheological performance and extreme pressure resistance, minimizes cutting temperature and cutting force for processing of metal pipe fittings, improves efficiency and accuracy of processing, reduces roughness of the workpiece and improves surface quality.

Description

technical field [0001] The invention relates to a metal pipe fitting processing lubricant, 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 grinding of ...
