Description
Affiliated field
The present invention relates to the coin manufacture method, relate in particular in coin, souvenir badge limit portion and be printed on a kind of coin of interval half gear, the method that souvenir badge limit portion is printed on interval half gear.
Background technology
Along with the progress of modern industrial technology, the especially progress of EDM Technology, coinage technology in various countries, the world today develops on inheriting tradition coinage technology basis brings up to a brand-new stage.Yet at present coin, the souvenir badge limit portion of various countries are still directly (tiltedly) tooth or the light face does not have a tooth single-mode.Can improve the manufacture difficulty and the technology content of coin, souvenir badge at coin, souvenir badge limit portion seal full-depth tooth interval half gear, has the popular anti-counterfeiting performance that strengthens coin, souvenir badge, and the sight and the collection that improve coin, souvenir badge, showed the progressive meaning of coin, souvenir badge manufacture craft.
Coin, souvenir badge limit portion seal full-depth tooth interval half gear is the manufacturing technology with certain difficulty, how on a die sleeve, processes full silk tooth and half tooth, and this is the key point of processing.Because the silk tooth processing of impression die sleeve is normally processed by wire cutting machine tool.Directly process in this way half raw silk rings tooth, half tiltedly a silk tooth just become a difficult problem.
The applicant applied for " coin, souvenir badge limit portion are interrupted half tooth and printing method " on December 25th, 2003, application number is 200310119463.1, though processing technology can be implemented in coin, souvenir badge limit portion impresses out interruption half tooth, but, the die sleeve making processes respectively because being that employing is split type, combine with bolting after the processing, the insufficient strength of die sleeve can not be carried out large batch of production so again, and die sleeve split difficult processing, production cost height like this.And producing the used hold down gag of moulding process anchor clamps is a big spring, and big spring discontinuity in moulding process like this affects to half tooth symmetry of product limit portion.
Summary of the invention
The purpose of this invention is to provide the method that a kind of coin, souvenir badge limit portion are printed on interval half gear, purpose is the coin edge made with this method for clocklike or irregular half raw silk rings tooth and half raw silk rings tooth or full raw silk rings tooth, partly oblique silk tooth and half oblique tooth or complete oblique silk tooth are alternately, tiltedly the silk tooth spiral is to comprising left-handed and dextrorotation, silk tooth gradient has increased anti-counterfeiting performance between 0 °～45 °.
For this kind of reaching above-mentioned purpose in the method that coin, souvenir badge limit portion are printed on interval half gear, comprise the steps: a, electrode be processed into the interval half gear electrode; B, processing die sleeve blank; C, interval half gear electrode and die sleeve blank are fixed on the spark-erosion sinking machine, use spark-erosion sinking machining silk tooth die sleeve then with anchor clamps; D, by the extrusion molding of metal, make the limit portion of impression back product form interval half gear; E, the product after impression finished withdraw from from die sleeve.
The interval half gear electrode processing of described step a is divided into the processing of compound electrode and the processing dual mode of overall electrode.
The processing method of described compound electrode comprises the steps: a1, electrode blank is made into A, B two parts; A2, with anchor clamps with the A partial fixing on wire cutting machine tool, be processed into thin tooth then; A3, with anchor clamps with the B partial fixing on wire cutting machine tool, be processed into close tooth with wire cutting machine tool then; A4, electrode A, B two parts connected by securing member tighten together, the silk tooth electrode and the securing member that are made of two parts have up and down just formed complete interval half gear electrode.
The processing method of described overall electrode comprises the steps: a11, makes electrode blank; A12, electrode blank is fixed on the engraving machine, is engraved as the interval half gear electrode then; A13, by securing member the interval half gear electrode is connected to tighten together and form complete interval half gear electrode.
Described step c electric discharge machining method is divided into translation and two kinds of methods of C axle rotation.
Described interval half gear is straight half tooth or half helical teeth at interval at interval, and the gradient of silk tooth is 0 °～45 °.
Described interval half helical teeth is left-handed or dextrorotation.
When being full helical teeth interval half helical teeth, described interval half gear relatively rotates between the imprinting apparatus of the die sleeve of steps d and the silk tooth die sleeve.
The gland and the fore-set of described imprinting apparatus are provided with circular shrinkage hole, are provided with in the circular shrinkage hole to make the stressed uniform holddown spring of imprinting apparatus.
Advantage of the present invention: six kinds of basic silk profile of tooth morphotype covers of the coin limit portion that the inventive method provides, widenable to profile of tooth difference (as round tooth, stepped tooth, rake tooth etc.), the different polymorphic interval half gear die sleeve of tooth pitch (distance between silk tooth and thread tooth), for making coin, souvenir badge limit portion shape provide multiple choices, and be the popular anti-counterfeiting technology of a kind of important coin, adapt to slot machine and test the coin requirement automatically, can make full use of in the production of common coin circulation, circulation commemorative coin, souvenir badge.The interval half gear technology has realized a breakthrough on world's coin, souvenir badge limit portion manufacturing technology, changed coin, the single present situation of souvenir badge limit portion manufacturing technology, and it is applicable to common continuous process units, and production efficiency can be guaranteed.
