Problems solved by technology

[0003] The existing production of precious metals mostly uses collective melting furnaces for metal melting, and then the molten precious metals in the furnace are manually transferred to the inside of the tablet pressing machine for pressing one by one, so that the inside of the collective melting furnace cannot be cleaned well, so As a result, precious metals are doped with many impurities, and particles and flocs in the air will stick to them during the manual transfer process, which will eventually lead to poor quality of precious metal products and affect sales, and pressing one by one will lead to low pressing efficiency If the output increases, it is likely that the precious metals in the later stage have cooled down, so the pressing effect is not good, resulting in the quality of precious metal products being unqualified

Embodiment 1

[0023] see Figure 1-2 , a tablet pressing device and process for precious metal production, comprising a base 1, a mounting seat 2 is arranged on the top of the base 1, and a lower groove 3 is arranged on the top of the mounting seat 2, and a lower mold 4 is arranged inside the lower groove 3, and The bottom end of the lower tank 3 is provided with a refrigerant 5, and the two ends of the top of the base 1 are provided with a support rod 18, and the top of the support rod 18 is connected with a mounting block 6, and the inside of the mounting block 6 is provided with a cylinder 7, and the cylinder The output end of 7 is connected with telescopic rod 8, and one end of telescopic rod 8 is connected with upper groove 10, and the bottom end of upper groove 10 is provided with upper mold 11, and one side of base 1 top is provided with connecting rod 12, and connecting rod 12 A rotating shaft 13 is arranged at the top of the connecting rod 12 through which a funnel 14 is rotated an...

Embodiment 2

[0026] Please focus on figure 2 , the base 1 is fixedly connected to the mounting seat 2, and the mounting seat 2 is a cylindrical structure, the number of the lower mold 4 is three sets, and the three sets of lower molds 4 are all cylindrical structures, and the refrigerant 5 is made of ammonium chloride and hydrogen oxide Barium composition.

[0027] In this embodiment: by providing the refrigerant 5, rapid cooling of the precious metal in molten state can be achieved, so that the precious metal can start to form, ensuring the efficiency of tablet forming, and three groups of tablet pressing at the same time can improve the compression rate. The speed of the tablet ensures the cost of the tablet.

Embodiment 3

[0029] Please focus on figure 2 A connection block 9 is connected to the bottom end of the installation block 6, and a telescopic rod 8 is arranged inside the connection block 9, and the connection block 9 is a cylindrical structure.

[0030] In this embodiment: the installation block 6 is to install the cylinder 7 (model is TDA20), which is convenient for pressing with precious metals, and the connecting block 9 is to install the telescopic rod 8 (model is GRA-L50), so that the telescopic The rod 8 and the cylinder 7 can cooperate with the work structure and are simple and easy to operate.

Abstract

The invention discloses a tablet pressing device and process for precious metal production, comprising a base, a mounting seat is provided at the top of the base, a lower groove is arranged at the top of the mounting seat, a lower mold is arranged inside the lower groove, and Refrigerant is provided at the bottom end inside the lower tank, support rods are provided at both ends of the top of the base, and the top ends of the support rods are connected with mounting blocks. The present invention realizes that solid precious metals can be placed and melted inside the funnel by providing a funnel, and the inside of the funnel is provided with an anti-adhesion coating, so that it will not stick to the precious metal and at the same time facilitate cleaning, so that no impurities will be generated inside the funnel, Therefore, the inside of the precious metal does not contain impurities, and the appearance is beautiful. By setting the lower groove and the rotating shaft, the precious metal in the molten state can be directly poured into the mold, without manual metal transfer, and the contact between the precious metal and the air is reduced. Reduce oxidation and particle adhesion, resulting in better quality precious metals.

Description

technical field [0001] The invention relates to the field of a tablet pressing device and a process for precious metal production, in particular to a tablet pressing device and a process for precious metal production. Background technique [0002] Precious metals mainly refer to gold, silver and platinum group metals (ruthenium, rhodium, palladium, osmium, iridium, platinum) and other 8 metal elements. These metals are characterized by high density (10.4-22.4) and high melting point (916-3000°C) , stable chemical properties, difficult to be corroded, most of these metals have beautiful color, are quite resistant to chemicals, and are not easy to cause chemical reactions under normal conditions. Precious metals are used to make jewelry and souvenirs, and there are also a wide range of Industrial use, used in electrical, electronic, aerospace industries. [0003] The existing production of precious metals mostly uses collective melting furnaces for metal melting, and then the...
