Embodiment Construction

[0009] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0010] see figure 1 and figure 2 , the implementation process of the embodiment of the present invention is as follows:

[0011] Step 101: Using copper as a raw material, the copper blank is obtained by die casting.

[0012] Step 102: Processing by a CNC lathe according to the size and matching position of the lower electroforming, and obtaining a high-precision blank after processing.

[0013] Step 103: Perform electroforming on the high-precision copper blank through the electroforming process of pure gold so that the electroformed deposition layer reaches a watch case of 0.05 mm to 0.35 mm. Electroforming uses raw materials such as gold or...

Abstract

The embodiment of the invention discloses a manufacturing method of a watchcase. The manufacturing method of the watchcase comprises the steps that a copper blank is machined according to an electroforming dimension and a matching position, so that a higher-precision blank is obtained; the higher-precision blank is electroformed through a pure gold electroforming process to make sure that an electroforming sedimentary layer of the electroformed blank is less than 0.5 mm, so that the watchcase is formed; gold or other precious metal is used during electroforming; the watchcase is machined according to the requirements for an assembly dimension, the matching position and the like; after nitric acid is heated to be boiled, the machined watchcase and the nitric acid are completely dissolved toform copper nitrate and are washed with water, then protective copper on the inner wall of the machined watchcase is heated and dissolved with sulfuric acid, and the watchcase is cleaned with water and then is dried to obtain a workpiece; and the workpiece is polished, so that the surface of the polished workpiece is glossy. By adopting the manufacturing method of the watchcase in the embodimentof the invention, the watchcase with light weight and good manufacturing precision can be manufactured.

Description

technical field [0001] The invention relates to the field of watches, in particular to a method for making a watch case. Background technique [0002] At present, the watch case materials on the market are commonly gold, K gold, gold-plated, titanium, stainless steel, semi-steel plated, alloy shell, etc. The metal walls of existing watch cases are all made of solid or hollow, which makes the metal watch too heavy. When using precious metals to make the case, the cost is too high. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a method for manufacturing a watch case with light weight and low manufacturing cost. A technical solution adopted by the embodiments of the present invention to achieve the above object is: [0004] A method for manufacturing a watch case, comprising: processing a copper blank according to the size and matching position of electroforming to obtain a blank with higher precision; and electrof...
