Embodiment 1

[0022] A method for manufacturing coins and medals with edge grooves of irregular shape, comprising the following steps: a, processing the electrodes into quincunx-shaped electrodes includes: a1, making electrode blanks, a2, fixing the electrode blanks on the engraved surface with a clamp machine, and then process it into plum-shaped special-shaped, a3. Connect the electrode handle and special-shaped electrode with fasteners to form a complete special-shaped electrode, such as image 3 As shown; b, processing the chip blank; c, fixing the complete special-shaped electrode and chip blank on the electric discharge forming machine with a jig, and then using the electric discharge forming machine to process the special-shaped quincunx-shaped chip, such as Figure 4 Shown; d, processing the upper and lower splints; e, combining the upper and lower splints and chips to form a bent plate; f, processing the disc, such as Image 6 As shown; g, fix the disc and the curved plate on the s...

Embodiment 2

[0025] A method for manufacturing coins and medals with edge grooves of different shapes, comprising the following steps: a, processing the electrodes into polygonal electrodes includes: a1, making electrode blanks, a2, fixing the electrode blanks on the engraving machine with a clamp , and then processed into a polygonal shape, a3. Connect the electrode handle and the shaped electrode with a fastener to form a complete shaped electrode; b. Process the chip blank; c. Fix the complete shaped electrode and the chip blank on the EDM with a fixture On the machine, and then use the electric discharge forming machine to process chips with special shapes into polygons; d, process the upper and lower splints; e, combine the upper and lower splints and chips to form a bent plate; f, process the disc; g, fix the disc and the bent plate on On the edging machine, through the extrusion of metal, the side of the flat cake after shaving is formed with grooves and special shapes; h, through em...

Embodiment 3

[0027] Step is with embodiment 1. The shape of the irregular shape in this embodiment is a triangle.

[0028] The coin edge groove technology of the present invention is a coin edge anti-counterfeiting technology, which is to process a circle of grooves on the coin edge by extrusion molding. Usually, the center of the groove on the edge of the coin can also be rolled with words or patterns. During the product printing process, the groove can protect the middle text or pattern, so that the text or pattern in the groove will not be squeezed out by the mold sleeve due to the deformation and expansion of the edge during embossing. The coin side groove rolling special-shaped technology, that is, on the basis of maintaining the circular structure of the protruding groove columns on both sides, a special-shaped structure is processed in the groove, and the combination of the groove and the special-shaped structure is realized on the side of the coin, forming a new type Anti-counter...

Abstract

The invention discloses a method for manufacturing coins, in particular to a method for manufacturing coins and medals in which grooves at the edge of the coins and medals are profiled. A method for manufacturing coins and medals with edge grooves of irregular shape, which includes the following steps: a. processing the irregular electrode according to the design parameters; b. processing the chip blank; c. fixing the irregular electrode and the chip blank on the EDM On the forming machine, then use the electric discharge forming machine to process the chip; d, process the upper and lower splints; e, combine the upper and lower splints and chips to form a bent plate; f, process the disc; g, fix the disc and the bent plate on the smoothing machine , through metal extrusion forming, the side of the flat cake after smoothing is formed with grooves and special shapes; h, through embossing and forming, coins and commemorative medals with side grooves and special shapes are made. The invention improves the appreciation, collection and anti-counterfeiting properties of coins and commemorative medals.

Description

technical field [0001] The invention relates to a method for manufacturing coins, in particular to a method for manufacturing coins and medals in which grooves on edges of coins and medals are profiled. Background technique [0002] With the advancement of modern industrial technology, especially the progress of electric processing and engraving technology, the minting technology of various countries in the world today has developed to a new stage on the basis of inheriting the traditional minting technology. At present, the edge anti-counterfeiting technologies that are widely used on coins include wire tooth technology and word rolling technology. Visual effect, anti-counterfeiting function is very weak. Rolling shaped grooves on the edges of coins and medals can increase the difficulty and technical content of coins and medals, enhance the public anti-counterfeiting performance of coins and medals, and improve the appreciation and collection of coins and medals. The pro...
