Abstract
The present utility model discloses the coin chapter base material of the bushing stacked spelling engaged column rod of a kind of metal tube in coinage field.Coin chapter base material is formed through radial cuts by after the bushing stacked spelling engaged column rod of one or more metal tube, stacked spelling engaged column rod is coated by two or more metal bar radial direction, laminate and be composited, and the cross section of coin chapter base material is multiple geometrical pattern and special-shaped pattern.This coin chapter base material can make coinage coin base, chapter chapter base processed and emblem, emblem processed base.The advantages such as the present utility model has technique advanced person, pollution-free, product pattern is exquisite, wear-resistant, the life-span long, plane visual is directly perceived, public's resolution is high, electromagnetic signal is stable, anti-counterfeiting performance is strong.
Description
Technical field
The present utility model relates to the manufacture field of coin, circulation coin, commemorative coin (chapter) badge and chip (game money), more particularly, the present invention relates to the coin chapter base material that a kind of pattern fineness, recognition performance and anti-counterfeiting performance are strong.
Background technology
At present every country is at high face amount coin circulation in the world, and general extensive use bimetallic coinage technology in the manufacturing process of commemorative coin, its anti-counterfeiting characteristic is obvious, and machine-readable dependable performance is stablized, and production efficiency is high, accelerate production capacity expansion.From nineteen eighty-two dozens of country so far, produce the bimetallic coin of nearly thousand kinds.Thereupon, the bimetal coin of false making is had to occur in euro area and Countries, so every country proposes again new requirement to the false proof of coinage.The a few countries such as France, Korea S, adopts various metallic plate punching core and ring in recent years, then bushing successively, print through printing machine again, make 3 metallic luster effects, antifalse effect has had new raising, but this production technology cost of manufacture is high, efficiency is low, design and limited to.
The manufacture craft of metal current commemorative coin and various badge is similar with it, also there are the problems referred to above.Chip (game money) is as a kind of currency carrier, and antiforge function requires higher.Owing to not being subject to state banking institutions management and control, therefore design space and the material scope of application are very wide, and anti-counterfeiting technology application is also of a great variety.The general plastics of inner embedding chip, pottery or the organic composite material of adopting high-end at present makes, but there is the defects such as cost is high, feel is poor, service life is short.Make the mode of two (many) looks coin material, adopt impact style combination, be only limitted to simple symmetric figure, pattern is single, and base material Sheet Metal Forming Technology stock utilization is low simultaneously.The method of kind of employing metal sleeve and cold drawing is had to make metal coin stamp base bar in currently available technology, cut into coin again, chapter base cake (patent application publication CN102293487A), this method designs at pattern space, there has been significant progress manufacturing process aspect, but it is stiff not break away from design yet, lack artistic feeling, technique is relatively simple thus cause identifying the drawbacks such as anti-fraud functional reduction, particularly single drawing process, easy metallic adhesion is not strong, and then cause producing between two or more metal loosening, affect the quality of coin chapter base material.
Summary of the invention
The purpose of the present utility model is to overcome the deficiencies in the prior art, provides the coin chapter base material of the bushing stacked spelling engaged column rod of a kind of metal tube, improves current coinage industry and manufactures and false proof level.
The purpose of the present utility model is achieved through the following technical solutions:
The coin chapter base material of the bushing stacked spelling engaged column rod of a kind of metal tube.Described coin chapter base material by the bushing stacked spelling engaged column rod of one or more metal tube in coin chapter base rod after, formed through radial cuts, described stacked spelling engaged column rod is laminated by two-layer or two-layer above metal bar radial direction and is composited, and the cross section of described coin chapter base material is multiple geometrical pattern and special-shaped pattern.
Described stacked spelling engaged column rod comprises pipe, rod and section bar.Described lamellar composite gold
Belonging to rod is non ferrous metal and their alloy, ferrous metal and alloy thereof and noble metal and alloy thereof.Described stacked spelling engaged column rod compound dilval.
Compared with prior art, the present utility model has following beneficial effect:
(1) utilize the natural colour of different metal and mutually laminate the design producing coin of composition, chapter, emblem have diversity, artistry, visual impact is strong;
(2) complicated, with high content of technology, the electromagnetic signal of processing technology is stablized, and has very strong antifalsification and very high public's resolution;
(3) wear-resistant, long service life;
(4) according to machine-readable requirement, specific identification material use laminated metal complex technique can be overlapped together, reaches the object of machine-readable anti-false;
(5) make the processing technology of coin, chapter, emblem than traditional plate stamping and blanking, stock utilization improves 5 ~ 10%, and has larger room for promotion, and material cost can be made greatly to reduce;
(6) insetting case technology adopts rolling, forging technology, and the bond strength between each layer metal is large compared with drawing process, there will not be the defect that interlayer loosens.
