Embodiment Construction

[0053] Attached to the following figure 1 -Attached Image 6 This application will be described in further detail.

[0054] The embodiment of the present application discloses a manufacturing process of a precious metal solid watch case. A manufacturing process of a precious metal solid watch case is implemented according to the following steps:

[0055] Step 1: Design a blank drawing for the product to be processed, design a mold according to the blank drawing and calculate the mass M of the product blank;

[0056] Step 2: Cut the precious metal into metal particles, install the mold on the rough blank machine, and electrically connect the mold with the rough blank, and deliver the metal particles from the feed port of the mold to the cavity in the mold according to the quality M;

[0057] Step 3: Heating the metal particles in the mold into molten metal, during the heating process, keep the air pressure in the cavity at 0.5atm-0.8atm;

[0058] Step 4: After the heating i...

Abstract

The invention relates to the technical field of watch case machining, in particular to a precious metal solid watch case manufacturing process which is characterized by comprising the steps that 1, a blank drawing is designed for a product needing to be machined, and a mold is designed according to the blank drawing; 2, precious metal is cut into metal particles, the mold is installed on a rough blank machine, the mold is electrically connected with the rough blank machine, and the metal particles are fed into the mold; 3, the metal particles in the mold are heated into molten metal; 4, inert gas is filled into the cavity until the molten metal is cooled to the normal temperature; 5, taking out the rough blank from the cavity, and polishing the rough blank; 6, an inlaying hole is formed in the rough blank through a tapping machine; 7, plating a layer of titanium film on the outer surface of the rough blank; 8, the jade is pressed into the rough blank, and then the rough blank is subjected to fine carving; and 9, the rough blank is put into a centrifugal finishing machine to be subjected to finishing, and the finished watch case is obtained. The watch case has the effect of meeting the requirement for manufacturing the watch case jointly made of precious metal and jade.

Description

technical field [0001] The present application relates to the technical field of watch case processing, in particular to a manufacturing process of a precious metal solid watch case. Background technique [0002] The case is usually the outer shell part of the watch body. Its function is to contain and protect the internal parts of the watch. According to the material, the case can be divided into: stainless steel case, tungsten steel case, ceramic case, aluminum case, Copper case, plastic case, etc. [0003] In the related art, the precious metal watch case is usually produced by the way of reverse molding. It is necessary to use gypsum to make a suitable mold, then heat the metal to a solid state, and then inject the metal into the mold by injection. After the metal is cooled, , take out the formed metal from the mold, and then grind and polish it, so as to realize the production of finished products. [0004] In view of the above-mentioned related art, the inventor beli...
