TOOL-ELECTRODE FOR ELECTROCHEMICAL MARKING Russian patent published in 2005 - IPC

FIELD: electrochemical marking of articles of electrically conducting materials.

SUBSTANCE: in base of tool casing is mounted. Said casing has lengthwise groove in which head is arranged. Said head is provided with set of numerical discs having teeth on their cylindrical surfaces. In casing are mounted: mechanism for changing order numbers having ratchet with pawl spring-loaded to it and locking members mounted with possibility of engaging with teeth of numerical discs. Tool is provided with spring for returning casing to its initial position. Locking members are in the form of pinions mounted on shaft in casing. Teeth of said pinions are inclined by angle 60° and they may engage with teeth of rotary discs mounted together with numerical discs. Dielectric is arranged between teeth of numerical discs; height of dielectric exceeds that of tooth by value of inter-electrode gap.

EFFECT: improved design of tool providing simplified process and lowered time period of marking.
