Abstract

The invention discloses a supercritical composite electroplating drill bit machining device based on swept cathodes and a use method and belongs to the technical field of electroplating machining of the drill bits. A transmission mechanism is arranged in the axial direction of an anode assembly in a reaction pool, the transmission mechanism is located below the anode assembly, and the transmission mechanism is provided with a clamping assembly and a cathode electric brush assembly matched with the transmission mechanism. The anode assembly comprises an insulated disk body located on one side of the reaction pool and an electricity conducting disk body located on one side of the corresponding face, to the insulated disk body, of the reaction pool. Multiple groups of anode electricity conducting posts are installed along the axis formed by the insulated disk body and the electricity conducting disk body between the insulated disk body and the electricity conducting disk body. The supercritical composite electroplating drill bit machining device based on the swept cathode and the use method achieve that in batch production, only one group of anode contact tube bodies are needed to correspond to multiple groups of machined drill bits, so that batch efficient production is achieved, the production cost greatly lowered, the electroplated drill bits are promoted to be widely popularized, and electricity waste caused by adopting an extra mechanical stirrer to conduct stirring is saved.

Description

technical field [0001] The invention relates to a drill bit for electroplating processing, in particular to a drill bit for supercritical composite electroplating processing based on a moving cathode and a use method thereof, belonging to the technical field of drill bits for electroplating processing. Background technique [0002] Supercritical fluid refers to a fluid between liquid and gas when a pure substance is above the critical point (critical pressure and critical temperature). Near the critical point, the density, viscosity, solubility, The physical properties of all fluids such as heat capacity and dielectric constant change rapidly. CO2 gas has the advantages of environmental protection, non-combustibility, non-toxicity, inertness, abundant reserves, and the critical pressure (7.39MPa) and temperature (31.1°C) are not too high, so super Critical CO2 fluids are widely used. Due to the low viscosity (0.03-0.1MPa·s) and high diffusion coefficient (10-4cm2·s-1) of su...

Problems solved by technology

[0005] The defect of the prior art is that when using this device, each group of anodes needs to correspond to a group of drill bits to be processed in mass production, and the electrodeposition time is 1-3h, so if you want mass production with high efficiency, you must produce The cost must be very high, but high-efficiency mass production cannot be achieved if the production cost is reduced, and the high production cost is not conducive to the widespread popularization of electroplating drill bits. The solution is stirred to drive the flow of the solution to further improve the uniformity and consistency of the nanocomposite electroplating process, and the use of an electrically driven mechanical stirrer will further increase the cost of power consumption and energy consumption, so a method that can reduce the use of electricity is required Drill bit for supercritical composite electroplating processing with low power consumption and high-efficiency production and its use method
