Problems solved by technology

[0005] In addition, in order to ensure its corrosion resistance, 316L steel has added a small amount of nickel to the steel, which will cause nickel to dissolve when it comes into contact with human skin, causing allergic reactions in some people, which is harmful to the human body.

Abstract

The invention discloses a method for manufacturing a watch appearance part, and relates to the field of watch part manufacturing. It includes optimizing the structure of the watch appearance parts, making corresponding water-cooled copper molds according to the design structure; pouring the raw materials of the amorphous alloy into the magnetic control electric arc furnace for melting, and casting them into master alloys after repeated melting; The alloy is remelted in a vertical vacuum die-casting machine to make an overheated melt; the melt is injected into a water-cooled copper mold and cooled to shape; the die-casting is roughly cut by laser or water jet cutting machine, and the sprue is removed , overflow port and large burrs; use CNC technology to perform simple machining on the cut die-casting parts; use wet grinding and wet polishing methods to polish the die-casting parts, and obtain the final parts after ultrasonic cleaning after polishing. The invention has excellent elasticity, better scratch resistance, biological friendliness and corrosion resistance, and is lighter and more comfortable to wear.

Description

technical field [0001] The invention relates to the field of manufacturing watch parts, in particular to a manufacturing method for watch appearance parts. Background technique [0002] The appearance of a watch includes a case, a bottom cover, a bezel, a buckle, a strap, etc., and each part has some specific functional and performance requirements. For example, a considerable part of the bezel and the bottom cover are elastically deformed and fixed to the case by interference fit during assembly, which requires the bezel and the bottom cover to have excellent elastic properties. The deformation of materials is divided into elastic deformation and plastic deformation. Elastic deformation refers to the phenomenon that the material deforms under the action of external force, and the deformation disappears completely when the external force is removed; plastic deformation is a deformation phenomenon that cannot be recovered by itself after generation. In the industry, the quan...
