Abstract

A precise eelctroforming technology by the cathode moving friction method includes such steps as filling hard particles in electrocasting bath, burying the electrocasting core mould in the hard particles, and moving the core mould to make said hard particles to rub and impact the surface of core mould for removing air bubbles and deposited layer, decreasing the thickness of diffused layer and increasing electrocasting speed and quality. Its apparatus is composed of motor, electrocasting bath, partition, liquid tank, magnetic pump, filter, ball valve, overflow valve, temp controller, heater, power supply, conductive device and electroforming processing device composed by transmission, core mould, hard particles and anode.

Description

technical field [0001] The precision electroforming process and device of the cathode movement friction method of the present invention belong to the precision electroforming process method and device. Background technique [0002] Electroforming is a precision special processing method. It uses the principle of electrodeposition of metal ions on the surface of the cathode to form parts, and has high replication accuracy and repeatability. Electroforming technology has been paid more and more attention in modern industry, and has been successfully applied to rocket engine nozzles, electromachining electrodes, armor-piercing powder covers, micro-mechanical components, aviation micro-sensors, micro-bellows, precision molds and other parts. manufacture. [0003] However, there are still some defects and limitations in the electroforming technology. For example, during the electroforming process, with the deposition of metal ions, gases such as hydrogen will be precipitated fro...
