TOOL FOR ELECTROMECHANICAL HARDENING OF SQUARE HOLES

摘要

The utility model relates to mechanical engineering, in particular to tooling for surface hardening, and can be used for hardening holes in square-section parts. The tool for electromechanical hardening of square-section holes contains a hardening tooth with a stop, made shaped, with slots between the working surfaces that form elastic segments, flattened mandrel installed in the guide, current-insulating sleeve. The reinforcing tooth in the cross section has the shape of a square, the slots on the reinforcing tooth are made mutually perpendicular and are located parallel to the sides of the square with the intersection point in the center of the square section of the reinforcing tooth, in the tail part the guide contains a thread on the outer cylindrical surface onto which the current insulating sleeve is screwed. for electromechanical hardening of square holes will provide surface hardening of square holes, and the threaded connection of the guide with the current insulating sleeve will ensure reliable operation of the tool.
