Problems solved by technology

However, in the process of processing small-radius elbows, there will still be obvious quality defects such as large bending deformation, product wrinkling, and failure to meet the appearance requirements of the product itself under conventional process and equipment conditions. Very vulnerable to damage during the process, short service life

Abstract

The invention discloses a lubricating agent for steel pipe bending. The lubricating agent is prepared from the following components in parts by weight: 49 to 52 parts of hydrogenated base oil, 4 to 8 parts of 1,2-octylene glycol, 10 to 15 parts of castor oil, 9 to 13 parts of dipotassium sebacate, 1 to 2 parts of sodium tungstate, 0.6 to 0.8 part of zinc borate, 1 to 3 parts of nano molybdenum disulfide and 6 to 8 parts of ethyl silicate. The lubricating agent provided by the invention is environmentally friendly, safe and non-irritant, and the lubricating agent remained on the surface of equipment after use can be easily cleaned.

Description

technical field [0001] The invention belongs to the field of centrifuge accessories preparation, and in particular relates to a lubricant for steel pipe bending. Background technique [0002] The elbow is an essential part of the centrifuge piping system, which has the characteristics of no dead angle and easy cleaning. The bending treatment of the steel pipe is completed in the pipe bending machine. Generally, the pipe bending machine is composed of wheel molds, clamping molds, guide molds, mandrels and other components. During the bending and forming process of steel pipes, the inner materials are subject to mutual stress. Due to the extrusion effect, the material itself cannot extend outward, forming concave wrinkles. In order to prevent the product from being concave, it is necessary to add a rear guide mold to limit the free deformation of the product during the bending forming process; during the bending forming process, the outer steel pipe is affected. Due to the st...
