Embodiment Construction

[0019] Attached below Figure 1 to 4 The implementation of the patent of the present invention will be further described.

[0020] Such as Figure 1 to 4 As shown, a device for electrochemical machining of a cylindrical mask includes a liquid distribution 9, a front sealing end cover 7 and a rear sealing end cover 3. They are all made of aluminum alloy. The liquid distribution 9 includes an outer structure layer 9-2, a semi-circular arc-shaped structure layer 9-3, and an axially penetrating guide groove 9-4 placed between the outer structure layer 9-2 and the semi-circular arc-shaped structure layer 9-3. The groove depth of the diversion groove 9-4 is 1mm and the groove width is 0.65mm. The arc surface of the semi-circular arc structure layer 9-3 is provided with axially staggered and evenly distributed outlet grooves 9-3-3 and bosses 9-3-2. The arc radius of the arc surface of the semi-arc structure layer 9-3 is 20 mm. The central angle between the two adjacent outlet groov...

Abstract

The invention patent discloses an apparatus for electrochemical machining of a mask on a cylindrical surface. The apparatus includes a liquid matching body, a front seal end cover and a rear seal end cover. The liquid matching body includes an external structure layer, a semicircle arc structure layer, an axially through diversion trench disposed between the outer structure layer and the semicircle arc structure layer. The arc surface of the semicircle arc structure is provided with liquid outlet grooves and bosses distributed in a staggered and uniformly toward an axial direction. The adjacent liquid outlet grooves and the bosses have a central angle of 3-10 degrees. The bosses are provided with liquid inlets at equal distances (d) along the axial direction. The front seal end cover and the rear seal end cover are in detachable sealing coupling with two axial ends of the liquid matching body respectively. A drainage groove communicates with the diversion trench. The apparatus in the invention is conducive to the discharge of an electrolytic product in an inter-electrode porous medium filled type mask electrolytic machining method, can improve the flow field uniformity at an anode surface of a cylindrical workpiece, further improves the quality of the electrochemical machining, is especially suitable for electrochemical machining of cylindrical surfaces, and is simple in structure, easy to operate and low in process cost.

Description

Technical field [0001] The invention belongs to the field of electrochemical machining, and particularly relates to a device for electrochemical machining of a cylindrical curved surface mask. Background technique [0002] The micropit array prepared on the surface of the metal member can not only store lubricating oil, improve lubrication performance, and increase the service life of the workpiece, but also can increase the heat dissipation and mass transfer efficiency of the product. At present, the main processing methods of micropit arrays include electrical discharge machining, precision machining, laser machining, and electrochemical machining. As a form of electrochemical machining, mask electrochemical machining has become one of the mainstream machining methods for micropit array structures because it can be processed in batches. At present, the fixing method of the mask is mainly the bonding type, but the preparation process of this form of the mask is quite complicate...
