Lubricating and sealing method of hexagonal bionic texture of reciprocating column casing structure

Abstract

The invention discloses a lubricating and sealing method of a hexagonal bionic texture of reciprocating column casing structure, which belongs to the technical field of bionic metal surface project. The method comprises the following steps of: processing the shape of the bar blank of a No.45 steel on a lathe, clamping one end of the bar blank on a three-jaw chuck of the lathe, starting the lathe, and then lathing the bar blank; according to the program of tool walking routes of a numerical control milling machine for mechanically processing, mechanically processing the No.45 steel of which shape is processed, and then obtaining the texture of the No.45 steel of which surface is in a regular hexagonal shape; adopting an ordinary quenching and insulating process to quench at 840 DEG C, and insulating for half an hour; after water quenching, tempering to 280 DEG C, and insulating for one hour, so as to meet the hardness requirement. The invention adopts the bionic technology to process the hexagonal texture on the surfaces of parts of the column cylinder structures, such as pistons, plungers and pump cylinders, so that the sealing performance is ensured while the lubrication effect is increased, and finally friction is reduced and efficiency of pump is improved.

Description

technical field [0001] The invention belongs to the technical field of bionic metal surface engineering, and in particular relates to a manufacturing method of a bionic hexagonal texture structure. Background technique [0002] As an important and effective method at present, bionic technology has been applied in various fields. The reason why katydids and tree frogs can cling to tree trunks, branches and leaves is due to the liquid secreted from their toes and the thick "suckers". Later, some scholars made further observations and studies on its toes and found that the surface of each "suction cup" was composed of hexagonal texture. In nature, there are many substances whose constituent units are hexagonal in shape, such as honeycomb, graphene, cell body, etc. As a polygonal structure, the hexagon not only has excellent and stable mechanical properties, but also has some other characteristics. The hexagonal pattern is an effective way to fill the largest number of simila...

Problems solved by technology

However, due to the complex actual working conditions, the oil cannot completely cover its contact surface, which causes dry friction and reduces its sealing performance.
