Description

Technical Field [0001] The present invention relates to a texture processing apparatus for a precious metal accessory,

The present invention provides a working box capable of two-handed work, wherein a movable chuck is provided in the working box, wherein the movable chuck is fixed in a tightening and loosening manner by a driving motor while the movable chuck has various shapes, And diamond sand paper sheets are attached and bonded to the underside of the bars so that the noble metal accessories (various kinds of noble metal accessories The present invention relates to a method and apparatus for processing a textured pattern on a surface of a workpiece such as a workpiece, Or area (size) easily and conveniently This is because the quality of the textured product of the workpiece is greatly improved due to remarkably improved workability, and the depth of the texture pattern and the uniform quality of feeling are clearly expressed so that the plating thickness The present invention relates to a texture processing apparatus for a noble metal accessory and a method of manufacturing the same, which are characterized in that a texture is formed while being exposed.

Generally, in the case of jewelry or accessories made of gold or silver (hereinafter, referred to as a precious metal accessory), since it is a matte surface due to the nature of the material, it is a punching technique for giving a new texture and visual change to the surface, A method of forming a pattern imparting unusual texture to a visual effect that can diffuse light by forming fine irregularities on a specific site has become popular.

For example, a technique for forming irregularities on the surface of a precious metal accessory may be used to cause shot on a surface of a base material by colliding against a specific portion of a base material (accessory) for processing a shot made of fine sand and hard metal particles A so-called sanding treatment product is predominant.

However, in the case of the precious metal accessories processed by the previous sanding process, there is a tendency that the visual contrast and the texture change are insufficient as compared with the surface before the machining, which is less than the expectation of the consumer.

On the other hand, in the conventional punching technology applying the surface processing technique of the precious metal accessories, a product which is formed by using a sharp punch or a punch to finely and closely wipe the surface of the base material to form the concave and convex is being released.

However, in the case of such a pore product, the visual effect due to the diffuse reflection of light is remarkable in the uneven portion compared with the sanding treated product, and the contrast of the unprocessed portion is remarkably improved even in the roughness of the surface, In order to form the unevenness, a highly skilled person has to rely on manual work by using a manual tool such as an auger or a sword, thereby causing a problem of low productivity due to difficulty of work.

In order to improve this, Korean Utility Model Registration No. 20-0319722 (Registered on July 1, 2003) has developed a surface finishing device for precious metal accessories and is now used in the related art.

This surface finishing apparatus has an instrument body 10 having a drive unit (not shown) driven electrically by a hand-held size and a tank 11 capable of being chucked at its tip, A holder 20 made of a horizontal tube 21 and a vertical tube 22 mounted on the outer side of the horizontal tube 21 for switching power transmission direction of the driving unit to be switched, A driving shaft 40 which is chucked at the front end of the vertical tubular body 22 and is provided with a cam 41 at its tip end and a spring 32 having elasticity provided on the vertical tubular body 22, And a cam 41 which is circumscribed on the upper end of the pivot shaft 30 to forcibly lower the pivot shaft 30 while limiting the return motion of the spring 32 .

However, such conventional designs are formed in the form of handpieces (hand tools), which may cause fatigue and pain in the hands during work, and especially sharp and pointed needle-like needles are repeatedly used, It is difficult to freely process the substrate.

In other words, the conventional needle type handpiece processing method requires a lot of repetition time in the texturing process, which takes a long time and troublesome work, and it also causes a vulnerability to grip the tool with one hand while holding the workpiece with one hand, It is difficult to express the texture of the workpiece. In particular, the depth of the texture is shallow with respect to the surface of the workpiece, so that the portions treated with the texture in the post-process plating process disappear (the surface is obscured by the thickness of the plating) There is a problem that a texture processing is easily lost.

In addition, the conventional method has a disadvantage that the quality of the product is deteriorated because the workability is very poor when the workpiece has a large area or a curved surface.
