Description
Technical Field
The invention relates to the technical field of mechanical dies, in particular to an antique silver-element straight-edge tooth extrusion forming die.
Background
The Yinyuan is commonly called as the ocean, the foreign money or the lace money. Yuan Yin originated in Europe in the 15 th century and is the main currency of the Ministry of Yin. In sixteen years (1890), Qingting begins formal mass casting in Qingting and a dragon is arranged on the Qingting, which is called as "Longyang". For nearly a century, Yuan Yin has occupied an important place in the field of circulation in China. And the various types of silver elements can be more than eight hundred patterns.
After the new China is established, the people's bank of China starts to recover according to the silver dollar value in 1950. According to folk theory, part of the recovered silver dollars are melted and returned to the furnace, and part of the recovered silver dollars are collected in the national collection of receipts. Therefore, the surplus of folk Yinyuan is rare and is popular among people in collection. Even more, the day of precious silver dollar auction is as high as four hundred and more thousands, such as silver dollars in Hubei Ben province between the years of light. Therefore, the retro imitated yinyuan has potential domestic market as the current art, and for the collection enthusiasts who can not buy hundreds of just once yinyuan, the imitations can be full of eyes and good fortune, and the historic culture of China can be inherited.
According to the introduction of the Baidu, ancient coin making design masters have the following effects on the careful consideration of the silver element side teeth: firstly, theft prevention is realized; the silver coins are made of precious metals, so that the silver coins can be optimally stolen by being scraped by an illegal person, and the silver coins can be effectively prevented from being scraped by the illegal person due to the fine edge tooth lines. Secondly, protection is performed; the lines and the patterns directly attract the attention of people, and the manual collision in the circulation process is prevented to the maximum extent. Thirdly, anti-counterfeiting; the cutting technology and equipment of the side teeth are national patents, a coin making machine and a mould are not in the confidential scope and can be assigned, but the cutting technology and the utensil are not assigned, so that the private casting of the silver coins is well prevented. Fourthly, playing a role of decoration; these lines and patterns may increase the aesthetic appeal of the silver coin.
According to the advanced technology of the current industrial situation in China, the surface patterns of the silver elements are formed by electroforming and electric spark processes, the simulation rate of the product is almost close to the original effect, and the product cannot be distinguished by naked eyes of people in general. However, the edge teeth of the silver elements cannot be copied from the real objects, and a technician is required to perform research to obtain a higher simulation effect. Therefore, when identifying the silver yuan, the Tibetan of China identifies the silver yuan, the identification of the silver yuan side teeth is the primary key, and even the production age of the silver yuan can be directly judged.

Furthermore, the taper 221 is set to make the workpiece close to the center of the die sleeve 1 from the taper in the state of position deviation during the extrusion operation, so as to achieve the purpose of calibration and positioning in the operation state without manual alignment, thereby improving the working efficiency.
In one form, the radial locating portion 22 mates with the toothing formation assembly holding location 11.
In one form, the toothing-forming assembly 3 is made of high-carbon steel and is machined by a wire-electrode cutting machine after being machined.
In the working production, a bench drilling machine is used as auxiliary equipment, a clamping handle 21 of an extrusion head 2 clamps a chuck of the drilling machine, the drilling machine is powered off, silver elements with printing procedures completed on a machined part are placed in a silver element storage chamber 311 of a positioning ring 31 of an edge tooth forming assembly 3, an operator slightly pulls a lifting rod of the drilling machine to enable the extrusion head 2 to move downwards (the center is calibrated through taper 221), and the machined part silver elements are pushed to gradually fall off from a gear ring 321 of a combined tooth sleeve sheet 32 of the edge tooth forming assembly 3, so that the whole manufacturing process of the silver elements is completed.
The invention introduces that the gear ring 321 of the combined gear sleeve sheet 32 gradually falls off, which means that the edge teeth are gradually layered and fed by the multi-layer combined gear sleeve sheet 32 with different technical data in the processing process, and the single feed amount is reduced, so that the silver element surface plane of a processed part is prevented from being deformed due to overlarge pressure in the edge teeth processing.
