The electrode tool for electrochemical marking and method of its manufacture

 

The invention can be used in electrochemical marking details. The electrode-tool contains a conductive substrate and formed on its surface the marks of the magnetorheological fluid. Signs form by immersion in the magnetorheological fluid of the working surface of the electrode-tool. In the process of forming the electrode-tool create a magnetic field through a hosted with its opposite side of the coils, the cores which are removable signs of damage information from a magnetic material.

The present invention relates to mechanical engineering and can be used in electrochemical marking details.

Izvestaj the electrode tool for electrochemical marking on parts made of conductive materials [1], in which the characters are made of conductive adhesive material apply removable information by electrochemical method. In addition, it is not possible to sustain the size of the strokes in accordance with the requirements of the standards applied to signs.

There is also known a method of manufacturing an electrode tool for electrochemical marking [2], which is based on the electrode-tool perform risks required depth in accordance with a pattern applied marks, which set work items (wire, tape), and after fixing them, fill, outside of space and exposure to the working plane of the drawing unnecessary details underestimate the height of the etching.

However, this method does not apply changing information one electrode-tool. It has high complexity and limitations in the manufacture of electrodes-tools for surfaces of complex shape.

The invention is directed to obtaining a removable information marked by an electrochemical method detail without changing the detection electrode, the expansion of technological possibilities marking on surfaces of complex shape and reduce the sizes of the strokes in accordance with the requirements of the standards.

This is achieved in that the electrode tool for electrochemical marking contains that is I.

This is achieved in that the working surface of the conductive base electrode-tool marks shape of the magnetorheological fluid by immersing it working surface of the electrode-tool, create on the working side of the electrode-tool magnetic field using placed with its opposite side of the electromagnet, the core of which are removable signs of damage information from a magnetic material, and after the formation of marks remove excess magnetorheological fluid.

The invention is illustrated in the drawing, which in a vessel with magnetorheological fluid 1 submerged base 2 electrode 2 of nonmagnetic conductive material of the working surface 3. To the electrode tool 2 from the back side pressed electromagnets 4, the core of which are removable signs of magnetic material. The coils of the electromagnets supplied by a constant current from the power source 5. On the working surface 3 of the base 2 are formed signs 6.

The method is as follows.

On the basis of the electrode 2, is immersed in a magnetorheological fluid to the working surface 3, with the back side (top) of the electromagnets 4 are the magnetic forces, under the action of which the working surface of the electrode 3 are formed of the magnetorheological fluid 1 marks applied information 6. The set of characters is fixed magnetic field on the working surface of the electrode 3. Then compressed air to remove excess magnetorheological fluid. After that, the electrode-tool is used for the electrochemical labeling.
