Problems solved by technology

[0003] During the surface treatment of existing dials, it is necessary to press shiny sand to improve the ornamental performance and corrosion resistance. At present, sandblasting is a better method for surface treatment of watch dials, and it has been widely used in the market. The existing press sand There are good and bad processes, especially for the sandblasting of watch dials. The sandblasting effect is relatively poor. At present, a suitable process has not been found that can solve the problem of poor sandblasting effect. Therefore, we propose a watch dial decoration press shiny Sand treatment method

Embodiment

[0029] The invention discloses a treatment method for finishing a watch dial by pressing shiny sand. The treatment method comprises the following steps: preparation of shiny sand, preparation of a watch dial, pretreatment of the watch dial by sand pressing, curved sand treatment and electrophoretic coating treatment.

[0030] The specific steps of the processing method are:

[0031] S1: The preparation steps of shiny sand are:

[0032] (1) Raw sand heating: Put the raw sand through the cooling device and the oil-water separator successively, then put the raw sand into the sand storage box, and pass compressed air into the sand storage box, and then compress the air to complete the sand material Imported into the heating device, so that the raw sand can be heated to a certain temperature;

[0033] (2) Add the resin solution, urotropine aqueous solution and calcium stearate successively into the heated raw sand and stir it, then take out the evenly stirred raw sand and cool dow...

Abstract

The invention discloses a watch dial embellishing and flash sand pressing treatment method, and belongs to the technical field of watch dial embellishing and flash sand pressing treatment. The method comprises the steps of flash sand preparation, watch dial preparation, sand pressing pretreatment on a watch dial, arc-shaped sand treatment and electrophoretic coating treatment, the watch dial is stamped and formed into a required shape, and then mirror polishing is conducted on the stamped watch dial to achieve a bright mirror effect. By conducting heat treatment on a workpiece at different temperature and different time, the workpiece presents different colors on the basis of different lines, so that the ornamental value and the corrosion resistance are improved; and flash sand is pressed on the dial by utilizing an arc-shaped sand process, and the dial is subjected to electrophoretic coating, so that the product has metal luster, the dial has both a sand surface effect and the mirror effect, and the corrosion resistance is also improved.

Description

technical field [0001] The invention relates to the technical field of pressing shiny sand for watch dial modification, in particular to a treatment method for pressing shiny sand for watch dial modification. Background technique [0002] Surface treatment is a method of artificially forming a surface layer on the surface of the base material with different mechanical, physical and chemical properties from the base. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. , for metal castings, our more commonly used surface treatment methods are mechanical grinding, chemical treatment, surface heat treatment, surface spraying, surface treatment is to clean, sweep, deburr, degrease, descale, etc. on the surface of metal workpieces, spray Sanding is the process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as...
