The technical FIELD TO WHICH the INVENTION RELATES.

The invention relates to a tool, in particular to a method of marking tool so that the tool had a clear, strong and aesthetically pleasing label.

BACKGROUND of INVENTION

For tightening a fastener such as a bolt or nut with thread, can be used wrench open maw, a wrench with a closed mouth, an adjustable wrench or a spanner. Set of Allen wrenches includes a handle and a set of heads of different sizes. When operating handle connected with one of the selected heads of specific size for tightening fasteners. Accordingly, a set of Allen wrenches can be used to tighten fasteners of various sizes. Set of Allen wrenches is easier and less expensive than a set of wrenches with open maw or wrenches with a closed mouth.

It is important marking heads set end wrenches to specify the size of the heads. Usually on the head, it is desirable to provide the model, logo or trademark. There was an approach, which is to provide a plastic cuffs of different colors on the heads. Plastic cuff can be easily stained, damaged or separated from the head t is thus, that head will have imperfect marking or generally will not be marked.

Alternatively, the marking may be performed by pressing. However, to perform such a pressing need an expensive machine. Moreover, impressed marks, it is difficult to recognize on the heads. This problem is compounded when pressed marks are filled with dirt and lubricant after some time of use.

The crown after pressing often applied electrolytic coating. Application of electrolytic coating is useful for protecting the head from corrosion. The electrolytic deposition of the coating on the cylinder provided inside and outside of the dent marks. I.e. the color of the inside of the depressed marking head is identical to the color of the outside of the deep tag. Application of electrolytic coating depressed makes marking more fuzzy.

There was another approach that after extrusion to provide a head manganese phosphated. The manganese phosphate is useful for protecting the head from corrosion. However, the phosphate of manganese gives the head a dark color, and pressed the marking becomes fuzzy.

Therefore, the present invention is intended to eliminate or at least mitigate the problems that occur in precede the eating level of technique.

The main objective of the present invention is to provide a method for marking instrument.

To achieve the above objective, the method includes the steps of providing a tool, performing thermal processing tool, ensure the soil layer on the instrument, perform the printing on the tool and applying electrolytic plating to the instrument. At the stage of fabrication drawing on clay layer provides a layer of paint. The paint layer includes at least one identification element. The identification element includes at least one identification area with paint, the background section provided around identification zone and free of any paint, and the boundary line provided around the background area and is equipped with paint. At the stage of applying electrolytic plating to the tool, the coating is provided in areas that are not covered in the identification area and the boundary line. There is a sharp contrast coating regarding paint coat.

Other objectives, advantages and features of the present invention will become apparent from the following description referring to the accompanying drawings.

DETAILED description of the IMPLEMENTATION OPTIONS

Referring to Fig. 1, shows how the marking instrument 10 shown in Fig. 2, in accordance with the first embodiment of the present invention. The tool 10 may be, for example, the head. The method includes the steps of molding, shaping, heat treatment, surface treatment, maintenance of soil, printing, coating and post-processing.

At the stage of casting the piece of metal is molded in cast billet (or "prototype").

At the stage of shaping cast the harvesting head 10 is shaped in accordance with the tip, which should be hooked and dragged the head 10. Step shape may include the stages of, for example, machining on a lathe, milling and drilling. When the head 10 is made in the direction of the axis of the two segments 11 and 12. The first segment 11 of the head 10 includes a square cavity defined therein in the direction of the axis, for receiving a square dowel handle. The second segment 12 of the head 10 includes a hexagonal cavity defined in the axis direction, for reception of a nut or screw heads. The head 10 comprises an outer surface and an inner surface. The external and internal surfaces of the heads 10 are collectively referred to as the surface 15 of the head 10.

Then head 10 is subjected to a step of heat treatment for the helicene her strength. Accordingly, the head 10 is less susceptible to wear.

Then head 10 is subjected to a step of surface treatment. The step of surface treatment may include the steps of grinding and processing stream fractions. Stage grinding is used to clean the heads 10 from burrs (or "rough edges"). The processing stage jet fraction is used for roughening, so that the surface 15 can be firmly fixed paint or coating.

Then, referring to Fig. 3, the head 10 may be subjected to phase supply ground for the formation of a soil layer 20 on the surface 15. Stage supply ground may include the step of coating black coating manganese phosphate or zinc or application of electrolytic coating. The ground layer 20 is preferably black for a sharp contrast as to the colors, which should be provided on it.

Next, referring to Fig. 4 and 5, the nut 10 is subjected to the printing stage to supply ground layer 20 layer 40 paint. For corrosion protection of the soil layer 20 provided on the surface 15 of the head 10, the layer 40 of paint can be made of transparent paint.

The layer 40 of the ink includes at least one identification element 30. Identification element 30 can be used to specify the size of the head 10, model, lo is atipa or brand. Identification element 30 includes identification zone 31 in a predetermined location on the soil layer 20, the background area 32 around identification zone 31 and the boundary line 320 around the background area 32. Identification zone 31 can include numbers, letters, symbols, and/or other suitable label. In the identification area 31 provides any paint, while on the boundary line 320 provides any other paint. Background section 32 is free from any paint.

And finally, referring to Fig. 6 and 7, the head 10 is subjected to the step of applying electrolytic plating to provide a coating 50 on the layer 40 of the paint, which includes an identification element 30. The coating 50 covers only the background section 32 of the identification element 30. The cover 50 is in sharp contrast relative to the layer 40 of paint that is transparent. More precisely, the cover 50 is in sharp contrast regarding identification zone 31 and the boundary line 320. Thus, the detection head 10 can remain accurate for a long period of time.

Referring to Fig. 8-11 shows the head 10, is marked by the method according to the second variant embodiment of the invention. The second option is identical to the first variant of implementation except for the different stage of dormancy the ASCI. As shown in Fig. 8 and 9, the identification area 31 free from paint, while the background area 32 is supplied with paint. In the background section 32 of the identification element 30, is made by way of the second variant of implementation of the present invention, the boundary line does not exist. Referring to Fig. 10 and 11, the cover 50 covers only identification zone 31.

This method of marking head is at least two advantages.

First, the surface 15 of the head 10 provided with an identification element 30. Identification element 30 includes identification zone 31 and a background area 32. The coating 50 covers at least one portion of the soil layer 20, which is open for applying electrolytic coating in the system area 31 or the background area 32, which is in sharp contrast relative to the layer 40 of the ink provided in the background section 32 or identification zone 31. Therefore, identification of the head is clear and reliable.

Secondly, the layer 40 of paint covers part of the ground layer 20, which is open in the system area 31 or the background area 32 of the identification element 30 provided on the surface 15 of the head 10. The layer 40 of the paint protects the area of the base coat 20 from corrosion.
