Embodiment Construction

[0023] In order to further understand the content of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0024] The micro-protrusion structure can effectively reduce wear, which has been verified in bionic mechanical tests. In the process of electrolytic machining, it is proposed to use 3 times of electrolytic forming, that is, 1 / 3 of the inner surface of each electrolytic machining. (Of course, other times of electroforming can also be used). Combined with the accompanying drawings, the specific processing implementation process goes through the following steps in turn:

[0025] (1) Reference figure 1 As shown, using the drilling technology, drill a tiny cluster hole structure on the elastic insulating sheet 2 and the conductive layer 3 (generally using inert metals, such as platinum, etc.), to obtain the tool cat...

Abstract

The invention provides an electrochemical machining method for micro-protrusions on the inner surface of a sleeve part, belonging to the field of electrochemical machining. According to the electrochemical machining method, an elastic insulating sheet with a tiny group pore structure is utilized, one surface of the elastic insulating sheet facing to the part is subjected to conductive treatment, a tool cathode is formed by a conductive layer of the elastic insulating sheet and the elastic insulating sheet, the sleeve part is taken as a tool anode, electrolyte is filled between the cathode and the anode, and the anode and the cathode are respectively connected with a positive electrode and a negative electrode of a power supply for electrochemical machining to produce micro-protrusion structures on the inner surface of the sleeve part. By adopting the electrochemical machining method provided by the invention, the micro-protrusion structures can be formed on the inner surface of the sleeve part, and the electrochemical machining method has the characteristics of high production speed of the micro-protrusions, low cost and the like.

Description

technical field [0001] The invention relates to the field of electrolytic machining, in particular to an electrolytic machining method for micro-protrusions on the inner surface of sleeve parts. Background technique [0002] In the field of dynamic lubrication of tribology, the theory of elastohydrodynamic lubrication is a new lubrication theory obtained by a series of studies on the microelastic flow generated by micro bumps on the basis of macroelastic flow. Microelastohydrodynamic lubrication theory breaks the traditional view in the field of machinery that the smoother the surface of mechanical parts in rolling contact, the better. The rough surface with micro-protrusion structure contact is conducive to the formation of elastic hydrodynamic oil film, which can improve the tribological characteristics. Instead of reducing the wear resistance of the surface of mechanical parts, it greatly improves the bearing capacity and service life. Therefore, it has become a major br...
