Abstract

The invention provides a gas insulation protection jacking electrolytic machining cathode system and machining method. The cathode system is mainly composed of a jacking cathode, a cathode head and a ventilation module. In the jacking electrolytic machining method, an electrolyte laterally flows, and high pressure gas positively flows; and the machined profile of a workpiece gradually stretches into the jacking cathode, the high pressure gas with the pressure being adjustable in real time is blown into the upper end of the ventilation module, forms a uniform gas insulation layer on the surface of the machined profile of the workpiece, blows the stray electrolyte flowing into the cathode towards a gas horizontal channel and is blown out of a ventilation groove of the side of the cathode head. By adoption of the gas insulation protection jacking electrolytic machining cathode system and machining method, the electrolyte in the machined area can be conveniently reduced, the influence of stray corrosion on the workpiece profile is reduced, surface quality of a part is improved, and stability of a flow field in the machining area is improved.

Example Embodiment

[0015] The specific implementation of the present invention will be described in detail as follows.
[0016] To implement the present invention-"a gas-insulated protective sleeve material electrochemical processing cathode system and processing method", the device mainly includes a sleeve cathode body, a cathode head, a ventilation module, a gas control module and a cathode tailstock.
[0017] The nested cathode body, cathode head and cathode tailstock are all made of conductive metal materials; the ventilation module and gas control module are made of non-conductive materials; the shape of the cathode blade groove of the cathode head can be designed according to the shape of the processed parts. The width of the ventilation groove on the side of the cathode head and the thickness of the horizontal channel of the ventilation module can be adjusted according to the processing conditions.
[0018] The process of electrochemically machining a workpiece using the present invention mainly includes the following steps:
[0019] Step 1: Install the cathode body assembly (casing cathode body, cathode head, ventilation module and gas control module) on the cathode tailstock, and connect the cathode to the negative electrode of the power supply;
[0020] Step 2: Install the workpiece and connect it to the positive pole of the power supply;
[0021] Step 3: Set the tool, determine the initial machining position, and calculate the initial machining gap;
[0022] Step 4: Install the fixture. Connect the electrolyte inlet and outlet with the electrolyte circulation system, and connect the gas inlet with the gas source;
[0023] Step 5: Turn on the gas source, adjust the air pressure, and blow high-pressure gas into the cathode system;
[0024] Step 6: Turn on the electrolyte circulation system and adjust the electrolyte pressure in the processing area;
[0025] Step 7: Turn on the power and perform electrochemical processing. As the processing progresses, the processed surface of the workpiece gradually extends into the inside of the sleeve cathode body, and high-pressure gas is blown into the cathode system from the upper end of the vent module, wraps the processed surface of the workpiece in the form of a gas insulation layer, and flows into the sleeve cathode A very small part of the electrolyte inside the body is blown to the gas horizontal channel, and the sleeve cathode body is blown out from the ventilation groove on the side of the cathode head, reducing the electrolyte on the processed surface of the workpiece and reducing the influence of stray corrosion on the surface of the workpiece;
[0026] Step 8: After processing, turn off the power, electrolyte circulation system and gas source in turn, and return the cathode system to the starting position.
