Problems solved by technology

[0002] Precious metal stamps mainly refer to the combination of gold foil or silver foil and plastic film by plastic sealing, in which the plastic film consists of upper and lower layers, and gold foil or silver foil is wrapped between the upper and lower layers of film; when the plastic sealing is completed, it forms the edge of the stamp The shape is straight, which is inconsistent with the actual structure of the edge of the stamp. In order to make the edge of the precious metal stamp a tooth structure, generally those skilled in the art would think of using a die for punching operations, because the thickness of the precious metal stamp is very thin , there are only a few tenths of a wire, and the precious metal stamp cannot be fixed by using a punching machine, resulting in the inability to operate during punching or the deformation of the punched out product that does not meet the requirements

Embodiment 1

[0024] Please refer to Figure 1 to Figure 5 , the precious metal stamp tooth edge forming device in the figure includes a cutting machine 1, a movable swing arm press 2, and a knife die 3; the above three components operate independently of each other.

[0025] The cutting machine 1 includes a cutting template 11 and a template support 12 for moving the template up and down. The cutting template 11 has two square cavities 111 inside, and each cavity has a protrusion 4 at the bottom edge. The cross-section of 4 is straight, and the main function of the cutting template 11 is to cut out the precious metal on the precious metal blank roll to form a square precious metal sheet for post-processing. The structure of the formwork support 12 can refer to the structure commonly used in existing molds, and this component is not an innovative point, so it will not be described too much.

[0026] The movable swing arm press 2 includes an operating horizontal platform 21, a movable press...

Embodiment 2

[0030] In the above-mentioned embodiment 1, the number of the cutting machine 1, the movable swing arm press 2, and the cutting die 3 is one. Since the above-mentioned parts are independent of each other, in practical applications, it can choose multiple; in addition, the cutting template 11 and The die 3 has two cavities, so that two toothed precious metal sheets can be processed at one time. In practical applications, the number of cavities can be increased, so that several precious metal sheets and plastic seals can be added at one time. The number of diaphragms, thereby improving production efficiency.

[0031] A method for forming a tooth edge of a precious metal stamp includes the following steps:

[0032] 1. Prepare the precious metal preform, and use cutting machine 1 to stamp and cut the precious metal layer on the precious metal preform to obtain square precious metal sheets with straight edges;

[0033] 2. Prepare the preform roll of plastic sealing film, and use c...

Abstract

The invention discloses a noble metal stamp toothed edge forming device and a method thereof. The noble metal stamp toothed edge forming device comprises a sheet cutter, a movable swinging arm pressing machine and a cutter die which are independent of each other, wherein the sheet cutter comprises a sheet cutting template and a template bracket used for enabling the template to move up and down; a square cavity is formed in the sheet cutting template; a bulge is arranged at the edge of the cavity; the cross section of the bulge is linear; the movable swinging arm pressing machine comprises an operation platform, a movable pressing arm and a base; the operation platform is fixed on the base; the movable pressing arm is movably fixed on the base and is capable of rotating; the square cavity is formed in the cutter die; the bulge is arranged at the edge of the cavity; the cross section of the bulge is tooth-shaped. By virtue of the noble metal stamp toothed edge forming device and the method thereof, the technical problem that how the edges of thin noble metal stamps are tooth-shaped can be solved.

Description

technical field [0001] The present invention relates to a method and a device using the method for performing corresponding actions on the edge of a very thin precious metal stamp such as a stamp with a thickness of 0.7 filaments to form a tooth edge. Background technique [0002] Precious metal stamps mainly refer to the combination of gold foil or silver foil and plastic film by plastic sealing, in which the plastic film consists of upper and lower layers, and gold foil or silver foil is wrapped between the upper and lower layers of film; when the plastic sealing is completed, it forms the edge of the stamp The shape is straight, which is inconsistent with the actual structure of the edge of the stamp. In order to make the edge of the precious metal stamp a tooth structure, generally those skilled in the art would think of using a die for punching operations, because the thickness of the precious metal stamp is very thin , There are only a few tenths of a wire, and the pre...
