Description

Tweezers-type Welding Handle {a pincette wedding handler}

The present invention relates to a welding contact (handle) of an electric welder using heat of electric resistance. More specifically, jewelry electric welding is performed by the user by using heat of electric resistance easily and conveniently when a user welds a precious metal welding object using a solder wire. In the handle of resistance welding machine, the handle forms a tweezers shape and the material component of the handle is made of silver to improve the efficiency of heat conduction so that the heat of the welder can be transferred to the chain to melt the solder wire. In order to cool the remaining heat of the handle for tweezers-shaped handle on both sides of the tweezer-shaped welding handle, characterized in that formed by the operation of a small pump to enable the cooling water to circulate the water and cool the heat.

In general, the conventional casting process for producing a large amount of the same precious metal janggu was composed of the following process.

First step:

We manufacture metal round models of jewelry (rings, necklaces, medals, bracelets, etc.) that can combine jewelry with the design to be manufactured.

Metallic materials used in the production of circular metal models could be made of metals with strengths such as gold (Au), silver (Ag), platinum (Pt) and palladium (Pd). Craftsmen can use silver (96.5%) and nickel (3.5%), silver (90%) and palladium (10%), silver (93%), palladium (5%) and nickel (2%) as alloys. .

Second process:

A rubber mold made of rubber is manufactured by using the metal round model manufactured in the first step. Rubber molds are too thick in the top and bottom, so it is difficult to cut, pull out the wax pattern, rubber is wasted from an economic point of view, and if the rubber mold is too thin, it may break when injecting wax. Should have

Third process:

Wax is injected into the internal molding space of the rubber mold manufactured in the second step and cooled to prepare a predetermined number of wax patterns having the same pattern as the metal circular model of the first step.

4th process:

After attaching a plurality of wax patterns manufactured in the third process to a large wax tree, the process of investing and filling the flask and filling the investment material (gypsum) is performed.

5th process:

The buried flask is loaded into an electric or gas firing furnace and burned by applying heat.

6th Step:

When the firing is completed and the casting tempreature of mold is reached, the flask is removed from the furnace and placed on a casting machine (vacuum suction or early centrifugal column), and a casting step is performed in which the precious metal is filled in the plaster mold.

7th Step:

After casting is completed, the gypsum is dismantled to obtain a finished product and finish for gloss.

Finishing is cutting and removing sprue from a casting with sprue, chemically cleaning the surface with chemicals, or shaping the surface using an electric machine.

The precious metals manufactured by the above process are manufactured by the welding process to produce the precious metal products. In the case of combining these precious metals, a solder welding method for soldering two metals to the solder melting point has been proposed. The welding method has a problem that the color of the welded part is discolored when soldering, and the joining part is not firmly joined and fixed even after soldering, so that the gap is visible or separated and separated from each other due to poor soldering when worn for a long time. .

In addition, the above solder welding method requires not only a professional soldering skilled worker, but also has a problem in reproducibility that a product of the same quality can not be obtained according to the skill of the skilled worker, and the production time of the precious metal which requires a large amount of production time due to the soldering time is long. There are many problems in the process, such as greatly reduced productivity and competitiveness.

Conventional jewelry welding uses gold, silver, and new main chains to generate heat with a hydrogen / oxygen welder to fire, and uses tweezers to melt the solder wire in the welded part. The training period was necessary and had to be used with the management burden for the risk of fire or burns and safety accidents due to user's carelessness.

Accordingly, the metal component of the tweezer-type handle of the electric resistance welding machine in use is made of copper, and the silver tip is attached to the welded part (the end of the handle) to compensate for the disadvantage, and the heat must be cooled in the air. There was a big problem in the continuous use for a long time because the situation is attached to the handle of the part in contact with the hand.

Accordingly, the present invention has been made to solve the conventional problems as described above, the purpose of which is a pin-type welding handle of the resistance welding of the electric resistance welder for welding gold, silver, new chains The purpose is to provide it to the user.
