Abstract

The invention provides a centrifugal shot blasting electroforming manufacturing method and device. Centrifugal force generated through rotation of a leaf disc is utilized for enabling an electroforming solution and spherical hard particles to be ejected and impact the surface of an electroforming core mold, accordingly, the reduction reaction is generated on the surface of the cathode of the electroforming core mold, a component with the needed shape is prepared in a deposition forming manner, and the electrochemical machining field in non-traditional machining is involved. Under the action of centrifugal force, the hard particles are thrown out together and hit the surface of the core mold, the rapid forming manufacturing of ejecting electro-deposition in the casting process is achieved, and the effect of the surface shot blasting strengthening processing is achieved. The rapid forming manufacturing and the surface shot blasting strengthening processing are synchronously combined, and therefore skin blister adsorption of the deposition and generation of accumulated protrusions can be effectively prevented; and the surface flatness and smoothness are improved, residual compressive stress can be generated for surface stamping, and the fatigue resisting strength of a casting layer is improved. The centrifugal shot blasting electroforming manufacturing method and device can be used for inner surface defect mending and performance intensifying of components, rapid preparing of functional materials and surface coating of cavity type components.

AI Technical Summary

Problems solved by technology

However, due to the effect of gravity, the electroformed layer of the mandrel buried in the bottom layer receives a large extrusion friction force, and the electroformed layer of the mandrel buried in the surface layer receives a small extrusion friction force, which will still cause uneven materials on the upper and lower sides of the deposition layer.

[0004] There are other methods to improve the quality of electrodeposition manufacturing, such as interrupting the deposition process, removing surface tumors and burrs through mechanical processing, and then performing secondary deposition; or using additives to improve the electrodeposition liquid formula, increasing the electrodeposition liquid temperature, changing Stirring speed and method, etc., but the processing effect is not ideal, and the obtained deposit layer often has defects such as cracks and even delamination, which reduces the mechanical properties of the parts
