Abstract

A tool marking method includes: a first electroplating step for forming a nickel plating layer on a surface of a tool by electroplating; a printing step for partially printing and forming a marking block on a surface of the nickel plating layer, wherein an peripheral block is defined on the nickel plating layer and surrounds the marking block; and a second electroplating step for forming a chromium plating layer by covering electroplating on the peripheral block without including the marking block, and the chromium plating layer surrounds the periphery of the marking block. The present invention can solve the problem that the marking pattern printed directly on the electroplated layer of the conventional tool is not easy to be firmly attached, and is more likely to fall off due to the external force, which cannot effectively and completely display the marking pattern.

Description

Tool marking method

The present invention relates to a processing method for forming a mark on a tool. The aforementioned mark may be the size of the tool or the manufacturer's trademark, which can avoid the printing of the traditional mark printed on the tool surface after a period of time. Unrecognized questions.

Hand tools often assist in tightening components that are difficult to rotate by hand, so hand tools are widely used in assembly plants, machinery factories, vehicle repair shops, or home repairs. They assist people to complete work or construction operations, so hand tools are Extensive development. In order to match various specifications and sizes, general hand tools mainly mark the size of the hand tool at an appropriate position on the surface of the hand tool to provide users with easy identification of the size of the hand tool and other information to facilitate the aforementioned driving operation.

At present, a common method of making a mark on a hand tool is to first electroplat the surface of the tool to form an electroplated layer of metallic color on the surface of the tool, and then to make a mark pattern on the electroplated layer by printing. However, this method can quickly produce a marking pattern that provides identification, but the printed marking pattern is covered on the metal color plating layer, and the marking pattern is not easy to be stably attached to the smooth surface plating layer during processing. It is easy to fall off under the condition of holding contact, friction, etc., and cannot display the marking pattern completely, and lose the rules of providing identification tools The effectiveness of the grid size and the appearance of the peeled printed marking patterns are also quite unattractive.

The main purpose of the present invention is to provide a method for improving the marking pattern printed directly on the electroplated layer of the conventional tool, which is not easy to be firmly attached, and is more likely to fall off due to external force, which cannot effectively provide the defect of displaying the marking pattern completely.

The first tool marking method mentioned above, wherein the thickness of the chromium plating layer from the surface of the nickel plating layer to the surface of the chromium plating layer is H1, and the thickness dimension of the marking block from the surface of the nickel plating layer to the surface of the marking block is H2, and H1 is 0.003 mm to 0.1mm, and H2 is 0.003mm to 0.1mm.

In the first tool marking method described above, H1 is equal to H2 so that the surface of the chrome layer and the surface of the marked block are in the same plane.

In the first tool marking method mentioned above, the marking block is made of insulating material.

The aforementioned first tool marking method, wherein the tool is a wrench or a socket.

The second tool marking method includes: first electroplating, tool A nickel plating layer is formed on the surface of the electroplating; laser cutting, the marking groove is cut by the laser on the nickel plating layer, and the peripheral side around the marking groove is the peripheral block; printing, printing and attaching the marking block in the marking groove; In the second electroplating, a chromium plating layer is formed on the peripheral block by electroplating and does not cover the marking block, and a reserved groove is formed on the corresponding marking block.

The aforementioned second tool marking method, in which the marking groove does not penetrate the nickel plating layer, and the depth dimension of the marking groove is H3, and the thickness dimension of the marking block is H4, and H3 is equal to H4, so that the surface of the chrome layer is Mark the surface of the block into the same plane.

The aforementioned second tool marking method, wherein the thickness of the nickel-plated layer and the chromium-plated layer is 0.003 mm to 0.1 mm.

In the aforementioned second tool marking method, the marking block is made of insulating material.

The aforementioned second tool marking method, wherein the tool is a wrench or a sleeve.

The first figure is a flowchart of the tool marking method according to the first embodiment of the present invention.

The second figure is a schematic diagram of the processing flow of the tool marking method according to the first embodiment of the present invention.

The third figure is a flowchart of a tool marking method according to a second embodiment of the invention.

The fourth figure is a schematic diagram of the processing flow of the tool marking method according to the second embodiment of the present invention.

Please refer to the first and second figures, where the first figure reveals the tool marks The manufacturing process of the method, and the second figure reveals the processing flow of the tool marking method. The tool marking method according to the first embodiment of the present invention includes the following steps: first plating, a nickel plating layer 2 is formed by electroplating on the surface of the tool 1; printing, a marking block 3 is partially printed on the surface of the nickel plating layer 2, and A peripheral block 21 is formed on the nickel-plated layer 2 and around the periphery of the marking block 3; the second electroplating covers the plating on the peripheral block 21 to form a chrome plating layer 4 and does not include the marking block 3, and the chrome plating layer surrounds the marking Block 3 weeks side.

By the above-mentioned manufacturing method, in addition to allowing the marking block 3 to be firmly printed and attached to the surface of the nickel-plated layer 2, the nickel-plated layer 2 is covered by the chrome layer 4 and surrounded by the marking block 3 to provide the marking block The three-periphery side is surrounded by the chromium plating layer 4. According to the invention, the marking block 3 is firmly attached to the nickel plating layer 2 and cannot be easily peeled off, so as to prevent the conventionally fallen marking pattern from providing effective identification.

To further illustrate the detailed features of the tool marking method of the present invention, wherein the thickness of the chromium plating layer 4 from the surface of the nickel plating layer 2 to the surface of the chromium plating layer 4 is H1, and the thickness of the marking block 3 from the surface of the nickel plating layer 2 to the surface of the marking block 3 The size is H2, H1 is 0.003mm to 0.1mm, and H2 is 0.003mm to 0.1mm.
