Description
Technical field
The present invention relates to coin field of anti-counterfeit technology, the coin class that more particularly to a kind of edge has figure line is produced
The manufacture device of product.
Background technology
At present, domestic and international coinage enterprise when coin edge figure line is made mainly by base cake (the half of coin
Finished product) edge rolling figure line technology realizing, i.e., by making the edge knurling mould of rolling figure line, using edge knurling device
Go out required figure line in base cake edge roll printing, therefore coin first obtains edge figure line, then be imprinted with equipment to obtain
Surface pattern, product edge figure line is random with positive back view line position relationship, edge is alphabetical, symbol etc. exists
It is easily deformed after impressing.Or by spark cutting technology, the edge figure line for being pointed to coin shape structure enters
Row cutting, so as to obtain processing effect.The processing mode such as Chinese invention patent of rolling figure line《Planchet
What cake edge rolling and slot rolling (word) were processed send cake positioner》, Application No. 201110426242.3, such as
Shown in accompanying drawing 7, it includes at least two rolling extrusion rotating disks, is provided with two rolling extrusion rotating disks, two rollings
The vertical direction of the line of centres of dynamic extruding rotating disk is provided with send cake device and positioner, two rolling extrusions
Rotating disk is provided with base cake and stirs drawing mechanism.The mode of production of this rolling processing its Stability Analysis of Structures, processes energy
Power reliability, accuracy can obtain certain guarantee, it is possible to obtain spread.But, it is this
Rolling processing is the processing of either simplex sequence, is merely able to the independent edge surface processing for carrying out coin class product, thus
So that Surface Machining and rolling processing must separate carrying out, its operating efficiency just originally greatly reduces.
Such as Chinese invention patent again《Edge has coin of geometric pattern and preparation method thereof》, application
Number it is 200610117876.X, discloses using electric discharge machining method and add carrying out coin class product edge decorative pattern
The method of work, although the machining accuracy of this processing mode is high, good product quality.But relative to punching press side
For formula, it is low that its working (machining) efficiency just seems particularly, and the degree of cooperation of operation is not high.
