A manufacturing device for coins with patterned edges

Abstract

The invention relates to the technical field of anti-counterfeiting coins, in particular to a manufacturing device of a coin product with patterns at the edge part. The manufacturing device comprises a die core and a die sleeve which is matched with the outer part of the die core; the die core is composed of a die seat, an ejector rod, an impression, an elastic component, an edge die pressing component and a die ring; the elastic component is arranged between the die seat and the edge die pressing component; the die seat and the ejector rod are matched to each other in parallel and bear the external thrust together; the impression is fixed at the front end of the axis of the die seat; the front end of the edge die pressing component is provided with the die ring and drives the die ring to close; the die ring is composed of multiple groups of independent die subrings; a pattern is formed in the inner cavity of each die subring; the ejector rod pushes the edge die pressing component; the die seat pushes the impression; and the impression acts on the center position of the die ring.

Description

technical field [0001] The invention relates to the technical field of coin anti-counterfeiting, in particular to a manufacturing device for coin products with patterned edges. Background technique [0002] At present, domestic and foreign coinage companies mainly use the technology of rolling the pattern on the edge of the blank cake (semi-finished coin) when making the edge pattern of the coin, that is, by making the rolling mold of the rolling pattern, and using the rolling equipment to roll the pattern on the blank cake. The required pattern is rolled out on the edge, so the coin first obtains the edge pattern, and then obtains the surface pattern through the embossing equipment. The positional relationship between the edge pattern and the front and back patterns of the product is random, and the letters, symbols, etc. Easily deformed after embossing. Or use electric spark cutting technology to cut the edge pattern located in the coin-shaped structure, so as to obtain t...
