Description

Jewelry wax inlaying process

Technical Field

The invention relates to the field of jewelry processing, in particular to a jewelry wax embedding process.

Background

In the field of jewelry processing, a technology of inlaying jewels by using wax is widely adopted to solve the problems of low operating efficiency and poor flatness, such as manual lifting, pearl absorption and the like, when the jewels are inlaid. In the prior art, the jewel is generally fixed by the stone claws, and when the jewel is embedded, the jewel can be clamped by the vacuum tweezers, and the jewel is pushed into the embedding position of the jewel by slight force and is grabbed by the stone claws; or, the preheated wax-inlaid pen touches the gem to heat the gem and slightly soften the wax around the gem, so that the gem is inlaid in the gem inlaying position.

However, due to the influence of high-temperature baking and cold and hot changes in the process of mould inversion (lost wax casting), the stone claws are easy to bend slightly and deform to lose the holding power on the jewel, so that the jewel is easy to drop the stone.

Disclosure of Invention

In order to overcome at least one defect in the prior art, the invention provides a wax inlaying process for jewelry.

The technical scheme adopted by the invention for solving the problems is as follows:

a wax inlaying process for jewelry comprises the following process steps:

step S1: manufacturing a wax mould, and arranging embedding positions and fixing columns on the surface of the wax mould;

step S2: carrying out primary embedding operation on the manufactured wax mould, namely preliminarily embedding the gem on the embedding position;

step S3: dipping wax with a color different from that of the wax mold on a welding needle of an electric soldering iron, utilizing the electric soldering iron to melt the top of the fixed column, melting the top of the fixed column, solidifying the melted top into a nail shape to clamp the gem, and fusing the wax dipped by the electric soldering iron and the fixed column to finish marking;

step S4: carrying out reverse mould operation on the wax mould embedded with the gem to obtain a rough blank of the metal jewelry;

step S5: and carrying out fine processing on the rough blank of the metal jewelry to obtain a finished jewelry product.

According to the wax embedding process for the jewelry, the top of the fixed column is hot-melted into a nail shape to clamp the jewel, so that the jewel is prevented from falling off, the quality of the jewelry is ensured, and the welding needle of the electric soldering iron is dipped in wax with a color different from that of a wax mold and then nailed during nailing, so that a worker can distinguish the nailed fixed column from the nailed fixed column which is not nailed through the color difference of the top of the fixed column, and the omission of nailing or repeated nailing is prevented.

Further, each of the gems is fixed by four fixing columns, and two fixing columns are shared between two adjacent gems. Two fixed columns of sharing between two adjacent precious stones have consequently reduced a large amount of fixed columns, reduce the preparation time of wax matrix, reduce later stage point nail time, reduction in production cost improves production efficiency.

Further, the embedding position is formed by inwards sinking the surface of the wax mould.

Detailed Description

For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 and fig. 2, the invention discloses a jewelry wax embedding process, which comprises the following process steps:

step S1: manufacturing a wax mould 1, and arranging embedding positions 2 and fixing columns 3 on the surface of the wax mould 1, wherein the embedding positions 2 are formed by inwards recessing the surface of the wax mould 1, a plurality of fixing columns 3 are uniformly distributed on the periphery of each embedding position 2, and the fixing columns 3 are roughly cylindrical or conical.

The wax pattern 1 is a first step of the wax inlaying process and is also an important step. The key problem of manufacturing the wax mould 1 is how to accurately control the size of the wax mould 1, when the size of the wax mould 1 is smaller, the gem 4 can be embedded into the wax mould 1 due to the flexibility of the wax, but after casting, the gem 4 expands under heat and shrinks when the metal solidifies, which can cause the breakage of the gem 4; on the contrary, when the size of the wax pattern 1 is too large, the gem 4 is not firmly embedded, and when the plaster pattern is poured, the gem 4 can be displaced due to the flowing of the plaster slurry. Therefore, when designing the wax pattern 1, the problems of the manner of embedding the gem 4, the shrinkage of the rubber mold, the shrinkage after cooling the wax liquid, the shrinkage when solidifying the metal, and the like are comprehensively considered so as to control the size of the wax pattern 1.

In the manufacturing process of the wax pattern 1 in the step S1, a plurality of wax patterns 1 may be manufactured into an integral wax tree, so as to improve the production efficiency.

Step S2: and carrying out primary embedding operation on the manufactured wax mould 1, namely, preliminarily embedding the gem 4 on the embedding position 2.

The gem 4 is a broad concept of gem, meaning a mineral or rock that is colorful, hard, durable, rare, and can be cut and carved into jewelry and art, including natural and synthetic, and also including partially organic materials such as amber, pearl, coral, coal essence, etc.

After the wax pattern 1 is manufactured, the gem 4 needs to be embedded on the wax pattern 1. Indeed, before setting the stone, it is first considered whether the setting stone 4 is suitable for wax setting. Generally, the jewel 4 with low hardness is not suitable for wax embedding, and the jewel 4 suitable for wax embedding generally requires high hardness and does not change color when heated at a certain temperature. In addition to these several factors, the size and style of the stone 4 has an effect on the end result. Smaller stones 4 are more resistant to thermal shock than larger stones 4, and stones 4 with smaller waist corners and sharper stones 4 are less resistant to thermal shock because the sharper parts are more likely to break. Therefore, the above factors are comprehensively considered when wax setting is carried out.

In step S2, when the gemstone 4 is wax-cut, the gemstone 4 may be gripped by vacuum tweezers and the gemstone 4 may be pushed into the setting site 2 with a slight force; or, the preheated wax-tipped pen touches the gem 4, so that the gem 4 is heated and the wax around the gem 4 is slightly softened, thereby preliminarily inlaying the gem 4 on the inlaying position 2.

In this embodiment, the gemstone 4 may be initially held by the fixing post 3; indeed, the wax mould 1 may also be provided with stone claws located at the periphery of the embedding location 2, through which the gemstone 4 is gripped.

Step S3: dipping wax with a color different from that of the wax mold 1 on a welding needle of an electric soldering iron, utilizing the electric soldering iron to melt the top of the fixed column 3, melting the top of the fixed column 3, solidifying the melted top into a nail shape to clamp the gem 4, and fusing the wax dipped by the electric soldering iron and the fixed column 3 to finish marking.

Specifically, the fixing column 3 is located on the periphery of the jewel 4, after the primary inlaying of the jewel 4 is completed, the electric soldering iron is used for hot melting the top of the fixing column 3, so that the top of the fixing column 3 is melted and solidified into a nail shape, the nail-shaped head of the fixing column 3 is pressed on the surface of the jewel 4 to clamp the jewel 4, the final inlaying and fixing of the jewel 4 are completed, the jewel 4 is prevented from falling off, and the quality of the jewelry is ensured.

In the present invention, since the fixing post 3 is too small, the difference in shape between the melted top of the fixing post 3 and the melted top is difficult to see, and thus it is impossible to distinguish from the shape which positions the fixing post 3 is nailed (i.e. the top of the fixing post 3 has been melted by the electric soldering iron) and which positions the fixing post 3 is nailed without some (i.e. the top of the fixing post 3 has not been melted by the electric soldering iron).

In step S3, in order to solve the above problem, in this embodiment, when the electric soldering iron is used to melt the top of the fixing post 3, the wax dipped by the electric soldering iron is melted with the melted wax on the top of the fixing post 3, and the wax dipped by the electric soldering iron is located on the surface of the nail-shaped head of the fixing post 3, so that the difference between the two wax colors is used to facilitate the worker to distinguish the fixed post 3 with a pointed nail from the fixed post 3 without a pointed nail by the difference between the colors on the top of the fixing post 3, thereby preventing missing of a pointed nail or repeated pointed nails.

After the step S3 is completed, preferably, in order to ensure the quality of jewelry, the setting quality of the gem 4 should be checked and trimmed, so as to ensure that the gem 4 is firmly set on the setting 2 and the gem 4 cannot be loosened or inclined; it should also be checked whether the surface and bottom of the stone 4 are covered with residual wax and removed to avoid the stone 4 being covered by the metal melt as a result of lost wax casting.

Step S4: and (3) performing reverse mould operation on the wax mould 1 embedded with the gem 4 to obtain a rough blank of the metal jewelry.

Wherein, the fine processing technology of the rough blank of the metal jewelry in the step S5 comprises the processes of grinding, polishing, electroplating and the like, so as to beautify the finished jewelry.

Referring to fig. 2, in the present embodiment, each of the gems 4 is fixed by four fixing posts 3, and two fixing posts 3 are shared between two adjacent gems 4.

Specifically, when the gems 4 are arrayed in the form of X × Y, the number of the fixed posts 3 is only (X +1) × (Y +1), and the larger the number of the fixed posts 3 can be saved when the number of the gems 4 is larger than the case where each of the gems 4 requires four independent fixed posts 3 to be fixed. Therefore, two adjacent precious stones 4 can be fixed by the two fixing columns 3 together, so that a large number of fixing columns 3 are reduced, the manufacturing time of the wax mould 1 is reduced, the later nailing time is reduced, the production cost is reduced, and the production efficiency is improved.

In conclusion, according to the jewelry wax embedding process provided by the invention, the top of the fixed column 3 is thermally melted into a nail shape to clamp the jewel 4, and when the jewel is clicked, the welding needle of the electric soldering iron is dipped with the wax with the color different from that of the wax mold 1 and then the jewel is clicked, so that a worker can distinguish the nailed fixed column 3 from the unfixed fixed column 3 according to the color difference of the top of the fixed column 3, the omission of the nailed fixed column or repeated nailing can be prevented, the jewel 4 can be prevented from falling off, and the quality of the jewelry can be ensured; two fixing columns 3 are shared between two adjacent gems 4, so that a large number of fixing columns 3 are reduced, the manufacturing time of the wax mould 1 is shortened, the later nailing time is shortened, the production cost is reduced, and the production efficiency is improved.

The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and such improvements and modifications are also considered to be within the scope of the present invention.
