Method and device for processing revolving parts by high-speed jet injection electroforming

Abstract

The invention provides a method and device for processing revolving parts by high-speed jet injection electroforming. The method is characterized in that an electroforming core mould is partially buried in an electroforming groove which is filled with hard particles or is in direct contact with a plated negative pole surface through a friction piece, so that the defects of accumulated tumors, burrs and the like on a deposition surface can be effectively removed by the friction of the hard particles or the friction piece on an electroforming layer; and a computer is used for controlling a jet nozzle to scan along with a certain track and cooperates with the rotary motion of the electroforming core mould at the same time, so that the exposed electroforming core mould surface is subjected to selective scanning electroforming so as to pile up the required parts layer by layer. The device of the invention mainly comprises a table movement mechanism, a negative pole rotation drive device, a control system, a temperature control device, an electroforming liquid circulating filter system and the like. The method and device for processing the revolving parts by high-speed jet injection electroforming of the invention are adopted, thus not only effectively removing the defects of hard spots, air holes, accumulated tumors and the like on the electroforming layer surface and manufacturing the electroforming layer with compact and even texture at higher deposition speed, but also abandoning the complicated negative pole female die of the traditional electroforming and rapidly and efficiently forming the revolving parts with different shapes and wall thicknesses by one step.

Description

Technical field [0001] The invention relates to an electroforming processing method and device, in particular to a processing method and device capable of continuously producing electroforming parts with good compactness, in particular to a high-speed jet jet electroforming processing method and Device. Background technique [0002] As we all know, electroforming technology has been successfully applied in many high-tech fields as a precision special processing method with high replication accuracy and repeat accuracy. The use of electroforming technology can produce all kinds of precision, special-shaped, fine and difficult-to-process parts with traditional technology, and can ensure high shape accuracy and dimensional accuracy. [0003] However, electroforming technology also has some defects and limitations. For example, the quality of the casting layer is unstable, and defects such as pitting, pinholes, build-up, burrs, stress, etc. are prone to occur. These defects will gradu...
