STEPS FOR MAKING INDEX ON A TOOL

Abstract

The present invention provides steps of making an index in a tool, and includes a step of preparing a semi-finished tool by using machine to prepare a semi-finished tool; a step of first electro deposited coating to attach a transparent layer on the semi-finished tool by way of electro deposited-coating; a step of laser engraving to make at least one recess in the transparent layer by way of laser engraving, and the at least one recess communicates with the outer surface of the semi-finished tool; a step of second electro deposited coating to fill colored material in the at least one recess by way of electro deposited coating to make the top surface of the colored material be in flush with the top surface of the transparent layer, and a step of trimming to obtain a tool.

Claims

1. Steps of making an index in a tool, comprising: a step of preparing a semi-finished tool: using machine to prepare a semi-finished tool; a step of first electro deposited coating: attaching a transparent layer on an outer surface of the semi-finished tool by way of electro deposited-coating; a step of laser engraving: making at least one recess in the transparent layer by way of laser engraving, the at least one recess communicating with the outer surface of the semi-finished tool, and a step of second electro deposited coating: filling colored material in the at least one recess by way of electro deposited-coating, a top surface of the colored material being in flush with a top surface of the transparent layer; a step of trimming: trimming the semi-finished tool to obtain a tool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0017] Referring to FIGS. 1 to 4, the steps of making an index in a tool of the present invention comprises the following steps:

[0018] a step S1 of preparing a semi-finished tool: using machine to prepare a semi-finished tool 1 which can be a socket, a wrench, a bolt, a nut or the like;

[0019] a step S2 of first electro deposited coating: attaching a transparent layer 2 on the outer surface of the semi-finished tool 1 by way of electro deposited-coating;

[0020] a step S3 of laser engraving: making at least one recess 21 in the transparent layer 2 by way of laser engraving, the at least one recess 21 communicating with the outer surface of the semi-finished tool 1;

[0021] a step S4 of second electro deposited coating: filling colored material 3 in the at least one recess 21 by way of electro deposited-coating, a top surface of the colored material 3 being in flush with a top surface of the transparent layer 2; and

[0022] a step S5 of trimming: trimming the semi-finished tool 1 to obtain a tool 4.

[0023] The at least one recess 21 forms a distinguishable portion which includes characters, numbers, codes or patterns, or a combination of the characters, the numbers, the codes or the patterns. The step of trimming uses a polishing machine or a sand-grinding machine.

[0024] The electro deposited coating applies coatings which generally have a very uniform coating thickness without porosity to objects such as metals. Even complex fabricated objects can easily be coated, both inside cavities as well as on the outside surfaces. The electro deposited coating is normally automated and requires less human labor than other coating processes. Therefore, transparent layer 2 is securely attached to the outer surface of the semi-finished tool 1, and the colored material 3 is the at least one recess 21 is not removed. The transparent layer 2 and the colored material 3 are resin with additives, and the transparent layer 2 and the colored material 3 have different colors which provide very good distinguishable features.

[0025] The top surface of the colored material 3 and the top surface of the transparent layer 2 each are a smooth surface. It is noted that the step of trimming uses a polishing machine or a sand-grinding machine to selectively make the outer surface of the tool 4 to be smooth, anti-slip or any desired surface condition. Of course, a rubber made coat can also be used to the outer surface of the tool 4. As shown in FIG. 5, the number of the at least one recess 21 can be multiple and have different shapes and sizes. The present invention makes the tools 4 have better distinguishable features, the colored material 3 exist for a longer time period and is not be removed.

[0026] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
