Abstract

The invention discloses a preparation method for a double-sided embossed leaf metal souvenir badge. The preparation method is characterized in that the preparation method of a thin blank cake adopts the production process of first blank cake blanking, blank cake performing and second blank cake blanking, the produced thin blank cake is dish-shaped with a thicker middle and a thinner edge, in the method, certain metal accumulation amount is preformed on the thin blank cake, thereby facilitating the stamping of double-sided embossed thin products. A thin printing mold adopts a female screw mold with different patterns, the surface of the mold has such surface processing effects of a mirror surface, sand blasting, and the like, and the layout and height of the patterns of the mold are limited appropriately. A novel double-sided embossed leaf metal souvenir badge is produced through the closed stamping method.

Description

The preparation method of two-sided burr relief type sheet metal souvenir badge
Technical field:
The present invention relates to the technical field of metal coin (chapter), specifically a kind of preparation method of two-sided burr relief type sheet metal souvenir badge.
Background technology:
Sheet metal souvenir badge in the market (thickness of this series products thinnest part≤0.50mm) mostly is the sheet product of concave-convex type, and promptly product is just, the figure line at the back side is identical, and wherein one but positive line, and another side is an internal or female screw.Its preparation method be just, the figure line of back of the body mould makes equally, one of them mould is made positive line, another mould is made identical internal or female screw.It is after employing evenly is rolled down to certain thickness to silver that the base cake is made, and a blank-forming after the annealed cleaning, by the mode of impression, is finished the making of product again.This kind preparation method is quite ripe, sheet metal souvenir badge product on the market also is to adopt this method to make mostly, but it only limits to make the sheet product of concave-convex type, and just can not make, sheet metal product that the back side all has different burrs.Because if take above-mentioned preparation method, so can be owing to the thickness of base cake is too thin, the amount of flow of metal is abundant inadequately during the product impression, and product is difficult for being pressed foot fully.To press sufficient product fully in order wanting in addition, to strengthen force of impression, the service life that also can reduce mould if too pursue.Therefore above-mentioned preparation method is not suitable for making the two-sided sheet metal souvenir badge product that all has different burrs.
Through adopting keyword domestic and international patent database is retrieved, and the relevant patent that detects analyzed, the manufacturing technology (Chinese patent CN200610025289, U.S. Pat 2002154290, European patent EP 1718182 etc.) that relates to relief type coin or commemorative coin is all arranged in the existing as can be seen disclosed domestic and international patent, but the just manufacture craft of commemorative coin relief pattern, image that major part relates to, these patented technologies are because of the preparation method's that do not relate to ultra-thin type double face burr embossment commemorative coin (chapter) technical essential, and are little with this problem relation.So this problem has certain novelty in the claim at home and abroad.
Summary of the invention:
The purpose of this invention is to provide a kind of just, the back side has the preparation method of the slim souvenir badge of different burr relief patterns, adopt this method can produce a kind of novel just, the back side has the slim souvenir badge of different burr relief patterns.
To achieve these goals, technical scheme of the present invention is: a kind of preparation method of two-sided burr relief type sheet metal souvenir badge, it is characterized in that: described preparation method comprises the steps: a, to being rolling to certain thickness metal strip, carries out base cake blanking; B, the base cake is annealed; The optical mode that c, processing and fabricating preform are used; D, the base cake is carried out preform impression; E, the base cake is carried out the secondary blanking; F, the base cake behind the secondary blanking is annealed; G, the base cake behind the secondary blanking is cleaned light decorations; H, required printing die and the mould circle of making; I, employing coinage special equipment carry out multi-impression and are shaped.
The present invention is by adopting the thin slice base cake preparation method of blanking of base cake → base cake preform → base cake secondary blanking, and suitably control the figure line layout and the figure line height of mould, in conjunction with the production technology that adopts closed impression, be made into a kind of brand-new just, the back side has the ultrathin souvenir badge of different burr relief patterns.That such souvenir badge has is slim, burr, difficult imitated characteristics.At first this series products is extremely thin, and its thickness only is about 1/4 of same specification product; Secondly it not only just, the back side has different burr embossing patterns, but also have certain figure line height; This series products is also difficult imitated in addition, adopts conventional imprint process, can't press sufficient product at all.As seen, this kind preparation method has broken through the manufacture craft of traditional thin slice souvenir badge, has certain innovation.
