Abstract

A tool marking method, comprising: first electroplating, wherein the surface of the tool is electroplated to form a nickel-plated layer; printing, namely printing a local part on the surface of the nickel-plated layer to form a mark block, wherein the nickel-plated layer is a peripheral block around the mark block; and the second electroplating step, namely, covering and electroplating the peripheral block to form a chromium coating which does not contain the marking block and surrounds the periphery of the marking block. The defects that the marking pattern only directly printed on the electroplated layer of the existing tool is not easy to be firmly attached and can not be effectively displayed under the condition that the marking pattern is easy to fall off due to external force are overcome.

Description

Tool marking method

Technical Field

The invention relates to a processing method for forming a mark on a tool, wherein the mark can be a size corresponding to the tool or a trademark of a manufacturer, and the problem that the traditional mark printed on the surface of the tool is blurred after a period of time and cannot be identified can be solved.

Background

Hand tools often assist in tightening assemblies that are difficult to rotate by hand, and therefore are widely used in assembly plants, machinery plants, vehicle repair yards, or home repairs to assist people in completing work or construction work, and are therefore being extensively developed. In order to match various specifications and sizes, a general hand tool mainly marks the specification and the size at a proper position on the surface of the hand tool, and provides information such as the specification and the size of the hand tool for a user to conveniently identify so as to be beneficial to the operation of the driving.

At present, the common method for making a mark on a hand tool is to electroplate the surface of the tool to form a metal-colored electroplated layer on the surface of the tool, and then to make a mark pattern on the electroplated layer by printing. However, the marking pattern produced by printing can be covered on the electroplated layer with metal color, the marking pattern is not easy to be stably attached to the electroplated layer with smooth surface in processing, and is easy to fall off under the conditions of holding contact, friction and the like, so that the marking pattern can not be completely displayed, the utility of providing the specification and the size of the identification tool is lost, and the stripped printing marking pattern is not beautiful in appearance.

Disclosure of Invention

The main technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art, and to provide a tool marking method, which improves the defects that the existing tool electroplating layer is only directly printed with a marking pattern, is not easy to be firmly attached, and cannot effectively display the marking pattern under the condition of being easily dropped by an external force.

The technical scheme adopted by the invention for solving the technical problems is as follows:

two embodiments of the tool marking method are listed below.

A first tool marking method, comprising: first electroplating, wherein the surface of the tool is electroplated to form a nickel-plated layer; printing, namely printing a local part on the surface of the nickel-plated layer to form a mark block, wherein the nickel-plated layer is a peripheral block around the mark block; and the second electroplating step, namely, covering and electroplating the peripheral block to form a chromium coating which does not contain the marking block and surrounds the periphery of the marking block.

In the first tool marking method, the thickness of the chrome plating layer from the surface of the ni plating layer to the surface of the chrome plating layer is H1, the thickness of the marking block from the surface of the ni plating layer to the surface of the marking block is H2, H1 is 0.003mm to 0.1mm, and H2 is 0.003mm to 0.1 mm.

The first tool marking method mentioned above, wherein H1 is equal to H2 so that the chrome-plated layer surface and the marking block surface form the same plane.

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

In the first tool marking method, the tool is a wrench or a socket.

A second tool marking method, comprising: first electroplating, wherein the surface of the tool is electroplated to form a nickel-plated layer; laser cutting, namely cutting a mark groove in the nickel-plated layer by laser, wherein a peripheral block is arranged around the periphery of the mark groove; printing, namely printing and attaching a mark block in the mark groove; and second electroplating, wherein the peripheral block is covered with a chromium coating formed by electroplating and is not covered with the marking block, and a reserved groove is formed above the chromium coating corresponding to the marking block.

In the second tool marking method, the marking groove does not penetrate through the nickel plating layer, the depth of the marking groove is H3, the thickness of the marking block is H4, and H3 is equal to H4, so that the surface of the chrome plating layer and the surface of the marking block form the same plane.

In the second tool marking method, the thickness of the nickel plating layer and the chromium plating layer is 0.003mm to 0.1 mm.

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

In the second tool marking method, the tool is a wrench or a socket.

The invention has the advantages of improving the defects that the marking pattern only directly printed on the electroplated layer of the existing tool is not easy to be stably attached, and the marking pattern cannot be effectively displayed under the condition of easy falling off due to external force.

Detailed Description

Referring to fig. 1 and fig. 2, fig. 1 shows a manufacturing process of the tool marking method, and fig. 2 shows a processing process of the tool marking method. The tool marking method of the first embodiment of the present invention includes the steps of:

first electroplating, wherein a nickel-plated layer 2 is formed on the surface of the tool 1 by electroplating;

printing, wherein a mark block 3 is formed on the surface of the nickel plating layer 2 by local printing, and a peripheral block 21 is arranged on the nickel plating layer 2 and around the mark block 3;

and a second electroplating step of forming a chromium plating layer 4 on the peripheral block 21 by covering electroplating and not including the mark block 3, wherein the chromium plating layer surrounds the mark block 3.

By the manufacturing method, the marking block 3 can be stably printed and attached on the surface of the nickel coating 2, the chromium coating 4 is covered on the nickel coating 2 and surrounds the marking block 3, and the circumferential side of the marking block 3 is protected by the chromium coating 4 in a surrounding manner, so that the effect that the marking block 3 is stably attached to the nickel coating 2 and is not easy to fall off is achieved, and the problem that the existing fallen marking pattern cannot provide effective identification is avoided.

Further illustrating the detailed features of the tool marking method of the present invention, wherein the thickness of the chrome plating layer 4 from the surface of the nickel plating layer 2 to the surface of the chrome plating layer 4 is H1, the thickness of the marking block 3 from the surface of the nickel plating layer 2 to the surface of the marking block 3 is H2, H1 is 0.003mm to 0.1mm, and H2 is 0.003mm to 0.1 mm. H1 is equal to H2, so that the surface of the chromium plating layer 4 and the surface of the indication block 3 form the same plane, i.e. the surface of the chromium plating layer 4 does not protrude from the surface of the indication block 3, and the lateral stress of the indication block 3 can be avoided.
