Abstract

A recognizable tool manufacturing method comprises steps: firstly providing a tool; forming a metal cladding layer on the tool surface to isolate the tool from being in contact with corrosion factors; arranging a color layer having certain shape on the metal cladding layer, forming a hollowed portion at the scope where the color layer covers the metal cladding layer, the hollowed portion having required graphic shapes; and forming more than one electroplating layer on the external surface of the metal cladding to cover the hollowed portion and the surface of the metal cladding layer excluding portions covered by the color layer. Because color contrast forms between the color layer and the electroplating layer, the hollowed portion highlights the graphic shape. It will not only peel off easily but also improves the recognition effect.

Description

Recognizable tool making method

The invention belongs to a tool identification technology, and the tool surface has a manufacturing method of graphic designation.

Common tools on weekdays, such as sleeves, fixed wrenches, adjustable wrenches, ratchet wrenches, screwdrivers, etc. In order to recognize the source and size specifications of the product, the manufacturer will help the user to easily understand the relevant information of the tool in the number, unit of the pattern, text or model of the tool mark.

Early identification structures have the following production methods:

One is cast or forged by the tool, and the desired graphic recognition structure is directly formed on the surface of the tool. This identification structure, whether protruding or recessed, must be plated so that the entire tool shines with the bright silver plating color, which can neither highlight the graphic part nor enhance the recognition effect.

There is a way to make the tool move forward, so that the molding body of the tool is first subjected to electroplating, and then a layer of color is attached to the plating layer of bright silver. The color of the color layer is different from the plating layer, and the graphic can be recognized. In part, it allows easy identification of relevant information about the tool. However, the color layer is attached to the smooth plating layer and is not strong enough, and is easily peeled off due to contact or friction, so the recognition effect is very short.

In order to solve the shortcomings of the prior art, the inventor of the present invention successfully developed a "metal tool manufacturing method", and applied for the invention patents of No. 7,448,121 and Taiwan No. I323689 to the United States.

The metal tool manufacturing method is very simple. First, a tool is provided. Then, a color layer is applied to a partial area of the tool surface. The color layer covers the surface of the tool with a hollow portion, and the hollow portion has a graphic shape; the last step is electroplating. A plating layer is formed on the surface of the tool, and the plating layer covers the hollow portion and a portion of the tool surface other than the color layer.

According to the tool produced by this method, not only the color layer is firmly bonded to the surface of the metal tool, but it is not easily peeled off or peeled off. Secondly, the color of the color layer is contrasted with the rest of the surface of the tool, together with the bright silver color of the hollow portion, which has a clear and outstanding recognition effect on the shape of the graphic to be presented.

The inventor of the present invention also has a "sleeve identification structure and a manufacturing method thereof", and at the same time, the application for obtaining the patents of the US invention No. 8,020,274, the Taiwan invention No. I378845 and the German invention No. 102009000400 are well documented.

The identifiable sleeve is manufactured by providing a sleeve; forming a concave portion with a marking pattern on the circumferential surface of the sleeve by a roller; heat-treating the sleeve; and coating a color layer on the surface of the sleeve and In the recess; in addition to the color layer of the recess, the remaining color layer is removed from the surface of the sleeve; since the color layer is not electrically conductive, a plating layer can be formed on the surface of the sleeve.

The sleeve manufactured by this method not only has the anti-rust effect, but also makes the concave portion and the surface of the sleeve have a clear color contrast, and clearly distinguishes the information content of the sleeve to be expressed by the identification structure. In addition, the color layer accommodated in the recess is not worn or peeled off by an external force factor, and the recognition period is relatively extended.

The inventor did not complacent, and in the spirit of excellence, finally developed a more complete method of making identifiable tools.

One of the main purposes of the present invention is to simplify the manufacturing process of the tool, shorten the production time of the finished product, and have multiple effects such as rust prevention and long-term identification.

Due to the above object, the identifiable provided by the present invention The tool making method includes providing tools, coloring and plating steps, and adding an anti-rust operation.

There are many kinds of tools, such as knives, shovel, planing, sawing, axe, chisel, clamp, drill, boring, boring, hammer, pliers, wrench, screwdriver, connecting rod, sleeve and screwdriver head, etc. The subject matter of the implementation.

This rust-preventing operation is arranged in front of the coloring step to form a metal coating on the surface of the tool to isolate the tool from rusting factors such as water, oxygen, other oxidizing or acidic substances. At the same time, it provides a good basis for the implementation of the subsequent plating process.

The metal coating referred to herein is one of the selective plating and hot dip methods applied to the tool surface.

In the case of electroplating, it is common to form a film of chromium or other metal into the exterior of the tool. The hot dip method is preferably hot dip galvanized to form a corrosion resistant film on the surface of the tool.

A color layer of a certain shape is arranged on the metal coating layer, a hollow portion is formed in a range in which the color layer covers the metal coating layer, and the hollow portion has a desired graphic shape to complete the coloring step.

The color layer is overlaid on the metal coating by spraying or printing. The color layer printed on the metal coating with a printing device is monochromatic. It is also possible to print the desired color layer on the metal coating by means of a multi-layer coloring method.

Since the constituent molecules of the color layer are not electrically conductive, more than one layer of the plating layer can be formed on the outer surface of the metal coating layer, and the final plating operation is smoothly performed, so that the plating layer covers the hollow portion and the surface of the metal coating layer except the color layer.

At this moment, the color layer is contrasted with the bright silver plating layer, so that the hollow portion is highlighted by the graphic shape, which is not easy to peel off, and can enhance the recognition effect. At the same time, the total thickness of the plating layer is greater than or equal to the thickness of the color layer, which is sufficient to protect the color layer from external force collision or friction, and is not easy to wear off or fall off, and the identification period is relatively extended.

Hereinafter, the objects, structures, and features of the related embodiments will be described in detail based on the drawings, and it is believed that the techniques, means, and effects of the present invention can be obtained from an in-depth and specific understanding.

Figure 1 is a flow chart of the manufacturing tool of the present invention.

Figures 2 through 5 are schematic diagrams of the tools for the manufacturing process.

Figure 6 is a partial cross-sectional view of the finished tool.

Referring to Figure 1, the manufacturing process of the present invention is illustrated starting with the step of providing a tool 10, following the steps of rust prevention 12 and coloring 14, and ending with the plating step 16. For the sake of convenience of detail, a metal sleeve is taken as an example to serve as a target for tool implementation.

In Fig. 2, the sleeve 22 has a basic profile with oppositely formed polygonal grooves (or holes) at both ends, in accordance with the requirements of the "provide tool" step.

As shown in Fig. 3, a desired metal coating 40 is formed on the surface of the sleeve 22 to complete the "rust prevention" operation. In the present embodiment, the metal coating 40 is formed on the surface of the sleeve 22 by a plating method. The metal coating 40 is rich in chromium or other metals and can cover the outer circumferential surface, the two end surfaces of the sleeve 22 and the groove wall (or the inner wall of the hole) for isolating contacts such as water, oxygen, other oxidizing or acidic substances. Corrosion factors.

Of course, the metal coating 40 can also be selectively applied to the surface of the sleeve 22 by a hot dip method. At this point, the metal coating 40 is preferably hot dip galvanized to form a corrosion resistant film on the surface of the tool.

Next, as seen in Fig. 4, a color layer 20 of a certain shape is disposed on the metal cladding layer 40, and a plurality of sequentially arranged hollow portions 21 are formed in a range in which the color layer 20 covers the metal cladding layer 40, and the "coloring" step is completed. The color layer 20 in the drawing is a thin ring shape surrounding the circumferential surface of the sleeve 22. Each of the hollow portions 21 has a desired graphic shape such as Arabic numerals and English letters.

Finally, the "plating" step of Fig. 5 is seen, the colored sleeve 22 is immersed in the plating solution, and after a period of electrolytic reduction reaction, a bright silver plating layer 30 is formed on the surface of the removed sleeve 22 to complete the entire process. Manufacturing process. Since the color layer 20 constitutes a non-conductive pigment, only the color layer 20 is insulated on the surface of the sleeve 22, causing the plating layer 30 to cover the hollow portion and the surface of the sleeve 22 except for the color layer 20.

Secondly, after a plurality of electroplating (for example, three times), the surface of the sleeve 22 and the hollow portion form a embossed surface, thereby highlighting the desired image and obtaining an excellent recognition effect.

Finally, as seen in Fig. 6, the color layer 20 has a hollow portion 21 in the range of the surface of the sleeve 22. The surface of the plating layer 30 is preferably higher than the color layer 20, and may be equal to or lower than the color layer 20.
