Embodiment Construction

[0028] Combine below figure 1 , figure 2 Specific description of the implementation of the present invention - "Using bipolar electrode micro-pit electrolytic machining method"

[0029] (a) Drill tiny group holes on the three-layer structure consisting of auxiliary anode (the auxiliary anode material is generally made of inert metal, such as platinum), an insulating layer, and a workpiece cathode to obtain a bipolar electrode 1;

[0030] (b) by clamping the tool, the auxiliary anode 7 on the bipolar electrode 1 is closely attached to the processing surface of the workpiece anode 2;

[0031] (c) Connect the workpiece anode 2 and the tool cathode 5 to the positive and negative poles of the power supply 3 respectively;

[0032] (d) The electrolyte 4 rushes into the tiny holes in the bipolar electrode 1 and reaches the processed surface of the workpiece anode 2

[0033] (e) Turn on the power and perform electrolytic machining.

Abstract

The invention relates to a micro-hole group electrolytic machining method and a bipolar electrode thereof, which adopts a bipolar electrode and belongs to the technical field of electrolytic machining. The invention is characterized in that the method includes the following steps: (a) manufacturing a bipolar electrode (1) provided with a through hole group structure and consists of an auxiliary anode (7), an insulated layer (6) and a tool cathode (5); (b) tightly binding the auxiliary anode (7) with a workpiece anode (2) on the bipolar electrode; (c) connecting the workpiece anode (2) and the tool cathode (5) with the anode and the cathode of the electrical source (3) respectively; (d) spraying electrolyte (4) on the surface of the tool cathode (5) in the way that the electrolyte runs through the through hole group of the bipolar electrode (1) to reach the surface of the workpiece anode (2); (e) connecting the electrical source (3) for electrolytic machining. The invention can significantly improve the localization and micro-scale processing capacity of electrolytic machining.

Description

technical field [0001] The invention discloses a method for electrolytic machining of fine group pits using bipolar electrodes and the bipolar electrodes, belonging to the technical field of electrolytic processing. Background technique [0002] According to estimates, about 30% to 50% of the energy produced in the world is consumed in friction loss. For example, the power consumed by dry friction of textile machinery is 85% of its total power; It also reaches 30% of the total power; the friction loss of modern automobile engines accounts for 20% of its power. According to the statistics of the United States, Britain, Germany and other countries, the expenditure related to friction and wear accounts for about 2% to 7% of the annual GDP of the national economy. In 2003, the GDP of my country's national economy was 1,169.4 billion yuan. If the cost of friction and wear was calculated at 5% of the GDP of the national economy, it would be a loss of 58.47 billion yuan. It can b...
