Casting method for patterned stainless steel watch case

Abstract

The invention discloses a casting method of a patterned stainless steel watch case, which specifically includes the following steps: raw material selection: take a stainless steel composite steel plate with a thickness of 20-50 mm; raw material cutting: cut the above stainless steel composite steel plate into a square bar; Shaped bar; torsion forming; round bar turning: using a lathe to clean the twist and oxide layer on the surface; making sheet metal; watch case manufacturing, and then performing wire cutting and CNC processing after the sheet cools to make it follow the design drawings The design size is completed and processed into a case; the case is pickled, and the above-mentioned produced case is soaked in acid solution, and it is taken out immediately after the surface of the case shows a clear contrast between light and dark. The new pattern stainless steel manufactured by the present invention has reasonable design and simple production process. There are exquisite textures inside and outside the watch case made of new materials, and these textures will not be lost due to long-term use, and the texture of each watch case is different. Yes, unique.

Description

technical field [0001] The invention relates to the technical field of watch production, in particular to a casting method for a patterned stainless steel watch case. Background technique [0002] Watches have been loved by people since their birth. The most basic and important function of watches is to provide timekeeping. Since the mid-19th century, someone put a chronograph watch on a belt and wore it directly on the wrist. It has been gradually improved and reduced in size. Beautify the style and develop into a watch. Until today. Watches are not only used as simple timing tools, but as accessories, and also as a symbol of personal identity. The design and material of the watch can reflect the different tastes of the wearer. [0003] In order to meet people's needs, watch manufacturers not only constantly update styles and types, but also have a variety of material choices for watch cases and straps. The most commonly used watch case materials are 304 and 316 stainless...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems in the prior art that "the surface of the watch case is treated with a series of processes such as electroplating, etching, and wire drawing. However, these processes can only be aimed at the surface of the material, and will cause wear after long-term use." The shortcomings of the patterned stainless steel case are proposed, and a casting method is proposed
