Problems solved by technology

[0004] If gold is used to make watch parts such as wreaths, letters, and hands, more fine processing procedures are often required to prevent the loss of gold materials. If the existing technology is used to directly process gold blanks into watch parts, it will often lead to The pattern of parts is blurred, the surface is rough, or unnecessary loss of gold is caused, and the processing accuracy of watch parts in the existing technology is not high enough to carry out more complex and detailed processing procedures

Embodiment 1

[0033] A manufacturing process of gold watch parts, specifically comprising the following steps:

[0034] S1. Blank making: the metal or metal alloy that can chemically react with hydrochloric acid, nitric acid or sulfuric acid is used to press the inner blank of watch parts with the same pattern on the upper and lower sides and symmetrical thickness, and then finish it;

[0035] S2. Electroforming: Electroforming deposition is performed on the surface of the inner billet of the watch parts after pressing to form a gold layer;

[0036] S3. Cutting: Use the cold cutting process to symmetrically cut the watch parts, and form two sets of watch parts at one time; the cold cutting process uses a high-pressure water jet cold cutting process, the jet water pressure is 800MPa, and 100 mesh is added to the water flow Silica as abrasive;

[0037] S4, remove the inner blank of the watch parts; the watch parts with the inner blank formed after the S3 cold cutting process are first placed...

Abstract

The invention relates to a manufacturing process of gold watch parts. The manufacturing process specifically comprises the following steps that S1, blank manufacturing is carried out, namely metal ormetal alloy which can be subjected to chemical reaction with hydrochloric acid or nitric acid or sulfuric acid is pressed into watch part inner blanks, wherein each inner blank is provided with the upper surface and the lower surface with the same pattern and has the thickness in a symmetrical mode, and then finishing treatment is carried out on the watch part inner blanks; S2, electroforming is carried out, namely, electroforming deposition is carried out on the surfaces of the watch part inner blanks after compression molding so as to form gold layers; S3, cutting is carried out, namely symmetrical cutting is carried out on the watch parts by utilizing a cold cutting process so as to form two sets of watch parts at a time; and S4, removal of the inner blanks of the watch parts is carriedout, wherein the formed water parts with the inner blanks which are subjected to the cold cutting process in the S3 are firstly placed in a nitric acid solution with the mass fraction of 68-72% for soaking, after the inner blanks of the parts are dissolved, the parts are taken out and cleaned by using ultrasonic vibration, then the parts are placed in a sulfuric acid solution with the mass fraction of 96-98% for soaking, and finally the acid pickling solutions are washed by using clear water to obtain the formed watch parts.

Description

technical field [0001] The invention relates to a manufacturing process of gold watch parts, which belongs to the technical field of clocks and watches and the field of metal processing. Background technique [0002] As an important timing instrument, wristwatches have been invented and used for hundreds of years, and are very popular because of their advantages such as accurate timing and easy portability. With the development of science and technology, the continuous improvement of living standards and art appreciation levels, people are no longer satisfied with the single purpose of watches as timing tools. People's decoration needs for watches gradually exceed their use needs, and watches gradually contain higher art. Therefore, the market for gold watches is getting bigger and bigger, and more and more consumers are buying precious metal watches made of gold. [0003] Batch wreaths, letters, hands, etc. are all important parts of watches, with various forms and complex...
