Embodiment
As Figure 1-3, working groove is made up of cell body 8 and bottom land 9, and cell body 8 is inserted on the bottom land 9 by sealing-ring 15.The both sides suitable for reading of cell body 8 are fixed guide 5 respectively, and by roller 2,11, motor frame 4 fixed electrical machineries 12, the output shaft of motor 12 drives described roller 2,11 by belt pulley, belt 13 and axle 14 on the guide rail 5.The lower end of described motor frame 4 is by connecting rod 3 fixed electordes 1, and electrode 1 is immersed in the interior electrolytic solution 6 of working groove, is placed with workpiece 7 on the insulated legs 10 in the bottom land 9 of working groove.Described electrode 1 and workpiece 7 are electrically connected with direct supply.
Add man-hour, workpiece to be processed 7 is placed on the insulated leg 10 of bottom land 9.The length of electrode 1 is slightly larger than the width of workpiece to be processed.In working groove, inject electrolytic solution 6, make its submergence workpiece to be processed 7 and electrode 1.Connect power supply then.At this moment, will have electric current to pass through between workpiece 7 to be processed and the electrode 1, according to principle of electric field, workpiece 7 and the distance between the electrode 1 to be processed are short more, and current density is big more, otherwise more little.The density distribution schematic diagram of electric current as shown in Figure 4.As can be seen from the figure, the surface that is in the workpiece to be processed 7 under the electrode has formed a high current density band, and promptly scanning strip 16.Scanning strip 16 can make the scanning strip zone satisfy the primary condition of differential arc oxidation fully.Simultaneously, because the surface-area of hollow edged electrode 1 is very little, also just limited the power supply total current.
By motor 12 drive electrodes 1, make electrode 1 along the vertical uniform motion of workpiece to be processed, and it is constant that electrode 1 is remained with the distance of workpiece to be processed.Make the surface of the inswept lentamente whole workpiece 7 to be processed of scanning strip 16, finish differential arc oxidation processing workpiece 7.
By designing different transmission rigs and electrode shape, we can make electrode make two-dimensional motion, three-dimensional motion or circumferential motion, finish the differential arc oxidation processing to super large outside surface, different in nature outside surface workpiece.
The cell body 8 of working groove and base 9 have been designed to split type, have connected by sealing-ring 15.When needing to handle the workpiece on big surface, can remove base 9, cell body 8 directly is placed on the big workpiece surface, and carry out the sealed against leakage connection, directly the super large work piece surface be carried out the differential arc oxidation processing treatment.
