Description
Technical field
The utility model relates to the manufacturing fields of the coin that circulates, commemorative coin, souvenir badge, and in particular, to a kind of oblique coin chapter.
Background technique
Since coin occurring, antifalsification is always the element of most critical in coinage technology.From most early in the increasing of coin surface
Add various anti-counterfeiting characteristics, started the double-colored or even polychrome coin occurred to modern age, the antifalsification of coin and coin chapter is constantly mentioning always
It rises.However, while anti-counterfeiting technology is constantly promoted, fraud technology also followed by.Currently, domestic and international bimetallic (double-colored coin)
It has been be widely used that, due to the color difference of two kinds of metals, the public is easy to differentiate, and also improves antifalsification.However, with skill is forged
The continuous improvement of art is gradually disintegrated by the anti-counterfeiting technology barrier that double-colored coin technology is formed by fraud technology before this.
Coin, coin badge blank cake are the basic elements for manufacturing coin or coin chapter.Traditional base cake is punched by board material vertical
It forms, there is no rake angle by the base cake of vertical punching, anti-counterfeiting characteristic is unobvious.
Polychrome coin chapter (more metallic combination coin chapters) is even more can not have oblique coin chapter.Because traditional polychrome coin chapter is logical
Cross to multiple sheet metal vertical punchings, and successively bushing, then will be bushing after the polishing of combination coin chapter, coining be finally made it is more
Kind metal polychrome coin or coin chapter.So oblique polychrome coin is made if necessary, then need to rush multiple sheet metal rake angles
It cuts out, it is then successively bushing again.Since after oblique impact, base cake has certain angle, prevent multiple metal base cakes are from direct
It presses together.Metal is made using metal sleeve and the method for cold drawing although disclosing in patent document CN102293487A
Then coin chapter base bar carries out the polychrome coin manufacturing method for being cut into base cake to bar.But the patent do not disclose it is any tiltedly
The information of shape coin, coin chapter, because oblique coin, coin chapter are since with certain inclination angle, common imprint process can be to oblique
Shape base cake generates correction or deformation.So oblique coin or coin chapter are never applied.
So although various coin chapters in the prior art improve antifalsification to a certain extent, with fraud skill
The raising of art, current technology are not able to satisfy anti-fake demand gradually.
