Metal identification piece and manufacturing method thereof

Abstract

The invention discloses a metal identification piece shaped by stamping metal base material, comprising an appearance surface, a back surface and a side surface connecting the appearance surface with the back surface, wherein, the back surface is opposite to the appearance surface; the appearance surface is a high mirror surface, the connecting point of the appearance surface and the side surface is a closed angle, and the side surface is provided with milling grain. The manufacturing method of the metal identification piece comprises the following steps: providing a metal base material with a high mirror surface serving as the appearance surface of the metal identification piece; milling a groove whose appearance profile corresponds to that of metal identification piece needed to be shaped on the high mirror surface, wherein, the thickness of the groove is 1 / 3 more than that of the metal base material; stamping the relative surface of the high mirror surface so as to cause that the metal base material ruptures and forms the metal identification piece along the groove. The appearance of the metal identification piece is the high mirror surface, the connecting point of the appearance surface and the side surface is the closed angle, and the side surface is light and has milling grain; thus, the metal identification piece has higher appearance quality.

Description

technical field [0001] The invention relates to a metal identification part and a manufacturing method thereof, in particular to a metal identification part formed by stamping and a manufacturing method thereof. Background technique [0002] At present, 3C (Computer, Communication, Consumer Electronic) electronic products have become an essential tool in people's daily work and life in modern society. In order to attract the attention of consumers and facilitate consumers to identify and select products of different types and brands, these electronic products often have exquisitely made metal logos (LOGO). As a symbol of high quality or brand, this kind of metal signage generally has a high appearance quality, and its appearance surface is usually a high mirror surface. [0003] A manufacturing method of an existing metal identification part comprises the following steps: [0004] (a) Stamping to form a workpiece with a predetermined shape; [0005] (b) Use the burr surfa...

Problems solved by technology

[0011] However, the manufacturing method of the above-mentioned metal marker firstly forms the workpiece by stamping, the surface of the burr surface of the workpiece is easily damaged due to pressure, and the smoothness is not high, and the opposite surface of the burr surface will produce a larger tensile stress due to greater tensile stress. Slump angle, in order to make the appearance surface of the metal marking parts smooth and have a high mirror effect, it is necessary to use the burr surface as the appearance surface and perform complex polishing treatment. At the same time, the side of the workpiece is easy to form burrs due to material fracture

The metal identification parts prepared by the above method have problems such as poor flatness of the appearance surface, uneven thickness, and large collapse angles at the connection between the opposite surface and the side of the appearance surface, thereby reducing the appearance quality of the metal identification parts
