As shown in Fig. 2, edge has the coin and souvenir badge of laser hologram image, difference with the prior art is, The edge of coin and souvenir badge is equipped at least one piece of hologram image setting area, and hologram image setting area is that plane (can be single Or multiple antarafacial planes), inclined surface or cambered surface (can outer convex globoidal or inner concave arc surface, or convex arc is both equipped in same cambered surface Face is equipped with cancave cambered surface again), hologram image setting area is formed with the diameter of axle direction of coin and souvenir badge edge to be run through or includes (border on simultaneously with coin front, rear surface or only border on front and back side).Hologram image and coin and souvenir badge edge column It is preferred that body plane or cylinder cambered surface, which connect and put down, or slightly evagination and indent, its convex or concave value is usually in 0.15 millimeter of model In enclosing.And it is further, the edge of coin and souvenir badge is equipped with the groove or intermittent groove of overall coherence, hologram image Setting area is set in above-mentioned coherent or intermittent groove.

In one embodiment, for circular coin, hologram image is produced in circular coin edge cylinder cambered surface, with edge column Body cambered surface connects flat and runs through (bordering on coin front, rear surface) (referring to fig. 2 a).Or circular coin edge can also be produced on On the facet of cylinder.Made facet refers to: along circular coin edge cylinder, by tangent or micro with periphery A chain-wales that are mutually outstanding or mutually cutting production, and laser hologram image 1(is made referring to fig. 2 b) on the chain-wales.

For special-shaped coin, edge include combine cylinder cambered surface and plane and in rule or irregular various side shapes.Tool For body, hologram image, can be with edge cylinder in special-shaped coin edge cylinder cambered surface 7 or on special-shaped coin edge cylinder curved surface 8 Cambered surface or curved surface connect it is flat, also can slightly convex or concave.For example hologram image and six arc side shape coin edge cylinder cambered surfaces connect and put down simultaneously Include (referring to Fig. 3 a) or hologram image be on the quincunx edge cylinder curved surface of eight valves, not only connect respectively with inner concave arc surface it is flat but also Flat (referring to Fig. 3 b) is connect with outer convex globoidal, also or hologram image is in the edge cylinder plane of regular hexagon coin, and and cylinder Plane connects flat and runs through (referring to Fig. 3 c).

In another embodiment, hologram image setting is set on reeded coin chapter in edge, specifically, whole in edge In the indent cylinder cambered surface of body groove or intermittent grooves and in cylinder plane, holographic illusion-colour image is made.Advantage is more novel More preferably with antifalse effect, the hologram image and on indent cylinder face is not easy to wear and touched.

For example hologram image is made in the cylinder cambered surface in circular groove, holographic illusion-colour image is continuous in circular coin edge In cylinder cambered surface in cylinder cambered surface in whole groove or in intermittent grooves, as shown in Fig. 4 a, 4b.

Or in the cylinder cambered surface in the whole continuous groove of special-shaped coin edge or intermittent grooves or in plane, production is complete Cease illusion-colour image.As illustrated in fig. 4 c, it is presented in the cylinder cambered surface in arc nonagon coin entirety groove for hologram image, Fig. 4 d is Hologram image is presented in the cylinder plane in straight hexagon coin intermittent grooves.

These above-mentioned hologram images can be hologram image one by one independent respectively, can also be with piecemeal independence Sub-hologram as 15, work in coordination in these sub-hologram pictures layout, be combined into the hologram image of an entirety (referring to figure 5).

In yet another embodiment, three-dimensional space Three-dimensional holographic illusion-colour image coin is made, is instruction edge holography illusion-colour The three-dimensional space Three-dimensional holographic illusion-colour image coin of image and 17 common combination of surface holography illusion-colour image.It has strong three The visual impact of dimension space three-dimensional holographic image (referring to Fig. 6).

The present invention and the combined coin product formed of other edge anti-counterfeiting characteristics, have and are superimposed anti-fake advantage.Cause can It synchronizes and is produced in same module and can once synchronously complete production, there is the synchronization and convenient advantage in production.

For example, with edge stealth, the combination of the novel silk tooth feature of edge.This kind of coin chapter has feature of the invention, and same When with " edge latent image ", " edge have be made of point, straight line, camber line, curve element silk tooth " it is one of with On anti-counterfeiting characteristic, combined coin chapter product.Such as the edge in the quincunx coin of eight valves, while there is hologram image 1, " side Portion has the combination for the silk tooth 19 " being made of point, straight line, camber line, curve element (referring to Fig. 7 a).

For another example, with the combination of conventional edge lettering anti-counterfeiting characteristic.This kind of coin chapter has feature of the invention, and simultaneously " edge lettering (character cut in bas-relief or type) ", " lettering (character cut in bas-relief or type) in edge groove " with routine are one or more to prevent Pseudo-characteristic, combined coin chapter product.Such as the edge in circular coin, while there is hologram image 1 in groove, " edge groove The combination of interior type 20 " (referring to Fig. 7 b).

Area of the edge of coin and souvenir badge of the edge with laser hologram image to stranding production method, with the prior art It is not, making step is as follows: a, the base cake edge of coin or souvenir badge is processed, in the upper and lower side of base cake edge Chamfering is processed respectively；B, the holographic dummy slider of production first, and the first holographic dummy slider is placed in module sheet by inlaying upper and lower side block On body；C, the edge of base cake is carried out to stranding using one group of module body for being inlaid with the first holographic dummy slider obtained in b step Processing, so that the base cake edge of coin or souvenir badge engraves prefabricated hologram image.

Preferably, in b step, the first holographic dummy slider is placed in production in module body first inlays deep gouge and to solid Surely the fixing threaded hole of upper and lower side block is inlayed, the first holographic dummy slider is by dummy slider ontology and the hologram image structure being located on dummy slider ontology At dummy slider ontology is planar body, arc ontology or the ontology equipped with fin；Module body middle part is equipped with groove, groove Two sides be equipped with trapezoidal oblique clamping side block 37, process to rubbing with the hands to base cake, clamping side block at initial position is formed with confession The notch 38 that base cake is sent into；The squeezing passage 32 passed through for base cake is formed between two pieces of module bodies disposed in parallel, is squeezed logical The width in road is less than the size of base cake diameter.In b step, first inlays placement arc cushion block 45 in deep gouge, to adjust holography The thickness direction of degree containing the Molded Depth position of dummy slider.

This edge has the following advantages the method for stranding;

1, module body and hologram photo had both been made firmly to be integrated, also simultaneously meet and guarantee module needed for intensity and Rigidity.

2, the processing and fabricating of hologram image and the necessary technical treatment of hologram sheet itself on hologram sheet are not influenced, it is complete to ensure Cease the quality of piece.The structure and production method of special arc, groove hologram sheet.

3, the position that module body inlays hologram sheet can change on demand, to adjust the holographic position for being located at product edge. In mosaic texture, the upper and lower position (i.e. degree containing Molded Depth can appropriately adjust) of energy appropriate adjustment hologram sheet reaches product edge The appropriate adjustment of hologram image upper and lower position.

4, due to production in hologram photo be easily-consumed products, in structure production easy to produce the replacement of hologram photo and Conversion between different product.

5, the production of the hologram photo with complex contour or the independent sub-hologram photo of piecemeal, combinable production On with a piece of hologram sheet, the time-consuming and laborious complex appearance cutting action of hologram sheet is significantly simplified and saved.

Specifically, by one group of pairs of planar shaped or arc surfaced module in this method, to coin semi-finished product edge Compressional movement of the opposite reinforcing to stranding is carried out, the reverse phase hologram image in module is transferred to coin edge.Holography module uses The structure of hologram sheet is locally inlayed in module body.

The production and technique of module body and mosaic texture: in the side that module body twists, it is unfolded by product edge bent Line (making necessary amendment on demand), progress NC super machining synchronous with the oblique rib in two sides, and make mosaic groove, fixed spiral shell The processing in hole etc., if groove product then increases the fin structure of production reverse phase in module body.Module body is made after processing Cure process.

The production and technique of coin blank cake: coin blank cake first completes the imprinting moulding of positive back surface embossment, and on base cake side Portion makes to form required technique chamfering, finally again to its edge to rub with the hands to complete the final side of the transfer and product of hologram image Portion's forming.

The production and technique of holographic dummy slider: single independence or the independent reverse tone hologram sheet of piecemeal are scribed on demand, is gone forward side by side Row inlays the accurate cutting of shape, and carry out on demand arc-shaped bend (or when inlaying assembly, the side of mechanical type pressing embowment Method).Or hologram sheet is first curved into arc surfaced, then the hologram pattern of reverse phase is scribed along arc surfaced.Similarly, if groove product then Inlay hologram sheet of the respective production with fin structure, and scribe in the structure of fin the hologram pattern of reverse phase.

The modular form for inlaying hologram sheet has arc surfaced and planar shaped.It is round-trip with a kind of inserted plane and straight line module below To the method for stranding with the hands and by taking it makes three kinds of typical edge holographic products as an example, this method is described in further detail and is illustrated.

Inserted plane and straight line module back and forth in the embodiment of the method for stranding with the hands, firstly, using it is pairs of, be inlaid with hologram sheet Plane and straight line module 30 is linearly to stranding.Have in module body edge and inlays the first holographic dummy slider 31.Pairs of straight line is holographic Squeezing passage size 32 between module is arranged to be slightly less than the diameter of semi-finished product base cake 33, to guarantee amount of compression appropriate, base Cake is located on fixed initial position and makees passive rotation with the movement of module, and the hologram image in module is transferred to coin edge (referring to Fig. 8).

Module body edge be formed with it is trapezoidal twist slot, the expansion track in the slot bottom rectilinear direction and the exhibition of product edge The curve opened matches.Circular coin is in a straight line along the expansion of slot bottom rectilinear direction, and special-shaped coin is in wave along the expansion of slot bottom rectilinear direction Unrestrained curve (developed curve depends on special-shaped coin side shape, can suitably correct), if groove product is then along the rail of slot bottom expansion Increase production fin structure on mark.It is formed with trapezoidal oblique clamping side block 37 in the two sides of the track of slot bottom expansion, clamping side block exists Initial position is formed with the notch 38(for base cake feeding referring to Fig. 9).

It is specifically a kind of using structure and production of screw connection fastening, holographic inlay part: in module body office First is made on portion position on demand and inlays deep gouge 39 and fixing threaded hole 40, the depth for inlaying deep gouge of special-shaped coin is hologram sheet The sum of thickness and arc cushion block.Plane holographic dummy slider 41, the cambered surface holography dummy slider 42 of form fit are made, production has same track Oblique clamping inlay side block 43 and inlay lower side block 44, and production arc cushion block 45(is only needed for special-shaped coin) referring to Figure 10. Make 46 appropriateness of degree containing Molded Depth of hologram sheet is adjustable, hologram image is made to be located at coin to twist on molding position in structure.

Arc cushion block 45(is sequentially placed in module body only needed for special-shaped coin), the first holographic dummy slider, inlay upper side block 43, lower side block 44, fixed with holding screw 47 again.It inlays side block 43 and lower side block 44 plays fixed hologram sheet, continues and inlay The side block on position both sides, the multiple action with holding module body strength and stiffness.

Edge dovetail groove and mosaic texture carve the synchronous time processing of equipment using multi-shaft interlocked numerical controlled engraving.Such as: straight nine Side shape holographic product twists in module body, processes the wavy path 36 of its slot bottom expansion and the trapezoidal oblique clamping side block of two sides 37 and first deep gouge 39 is inlayed, using four axis or the synchronous time processing of five-axle linkage computer carving machine equipment.

Inserted to set reeded linear module back and forth in the embodiment of the method for stranding with the hands, along module body, trapezoidal to twist slot bottom straight On the expansion track in line direction, increase production fin 49, corresponding interruption fin is then made if intermittent grooves.Circular coin is being opened up Fin is made on the straight line opened again, special-shaped coin makes fin again on the curve of expansion, and fin height is generally equivalent to or is slightly larger than Product depth of groove, and make first on demand on local location and inlay deep gouge 39 and fixing threaded hole 40.It is ibid chatted, fin Pass through the synchronous time processing of numerical controlled carving equipment with the trapezoidal slot that twists of edge.Separately make fin holography dummy slider 50 and keep with Module body fin size it is identical consistent, referring to Figure 11.

The manufacturing process of first holographic dummy slider is as follows: for plane holographic dummy slider 41, first on plane holographic dummy slider 41 The production of the independent hologram pattern of piecemeal is carried out, and inlay the matching cutting of shape.

The production of arc surfaced holography dummy slider 42: it is whole again after production planar shaped holography dummy slider to curve cambered surface, or first by plane Substrate makes hologram image after integrally curving cambered surface on it again.

It can separately be bent after making planar shaped holography dummy slider, when inlaying assembly at arc surfaced, i.e., using inlaying upper side block 43(arc Shape), inlay lower side block 44(arc), cooperation arc cushion block 45, by holding screw 47 by planar shaped holography dummy slider squeeze curve arc Face shape holography dummy slider 42.

Respective slot product, it is corresponding to increase fin holography dummy slider 50 of the system with fin structure and make hologram on fin Picture.Remaining method is same as above.Fin holography dummy slider 50 both can be integrated, or can be further logical using substrate 55 and fin holography item 56 It crosses bonding or welds the structure spliced (referring to Figure 12).

It makes the special processes chamfering of coin blank cake edge: being divided into initial 45 degree symmetrical big chamferings, forms surface relief print 45 degree of edge symmetrical small technique chamferings after system, to ultimately form the product side shape after hologram image transfer.

Product side shape after final hologram image transfer is symmetrical small by adjusting 45 degree of edge after surface relief printing Technique chamfering realizes that 45 degree of edge symmetrical small technique chamferings after surface relief printing are symmetrically big by adjusting initial 45 degree Chamfering is realized.In terms of base cake diameter dimension: after the product diameter after surface relief printing is transferred than final hologram image Finished product is slightly larger, usually between 0.06~0.28 millimeter.By base cake manufacturing process steps, reaches and effectively transfer hologram image simultaneously Product quality of edges made of making is good.

Edge has the coin of laser hologram image and the seperated die sleeve production method of souvenir badge, which is characterized in that production Steps are as follows: the position of a, the base pieshape scribed as needed and hologram image setting make valve more than one group and are inlaid with holography The seperated die sleeve of dummy slider, more valve fission die sleeves are by the integral die sleeve of close split and are sheathed on outside lower stamp, and with upper print The membrane cavity squeezed for base cake is formed between mould；B, after base cake is sent into the die cavity, upper stamp moves down pressurization, and base cake is sufficiently squeezed Reverse phase hologram image in pressure, die sleeve inner wall is transferred to product edge；C, after the completion of coining, upper stamp retracts, on lower stamp Top gradually discharges more valve fission die sleeves, under the vertex of a cone thrust of separation part simultaneously, and more valve fission die sleeves are along limit part Cone-shaped wall gradually move up and it is radial unclamp separation, finished product is ejected the upper surface of seperated die sleeve by lower stamp.

In a step, more valve fission die sleeves 78 are divided into the separate structure 70 of three valves or pintongs equal part, and more valves are seperated The conical surface is made in the lateral surface of die sleeve；The inner wall split of separate structure 70 becomes cavity forming area 71, and cavity forming area is equipped with multiple Second inlays deep gouge 72, and the top plan of separate structure 70, which is equipped with, inlays the top deep gouge 74 that deep gouge is connected, top with second Small stair 75 and top surface installation screw 76 are equipped in deep gouge 74；The second holographic dummy slider that L-type is embedded in deep gouge is inlayed, second is complete One end of breath dummy slider is anchored in top deep gouge 74 by screw.
