工作業(yè)方法。在這種情況下,如模具設(shè)計(jì)不合理或沒有安全防護(hù)裝置,就極易發(fā)生人身安全事故。五、結(jié)語模具技術(shù)水平的高低是衡量一個國家制造業(yè)水平的重要標(biāo)志之一。我國工業(yè)的進(jìn)一步發(fā)展要求模具行業(yè)向大型、精密、復(fù)雜、高效、長壽命和多功能方向發(fā)展。文章從模具的發(fā)展歷史出發(fā),總結(jié)了國內(nèi)冷沖壓模具的發(fā)展現(xiàn)狀。探討了國內(nèi)冷沖壓模具發(fā)展的新方向我國模具工業(yè)雖然有了很大的發(fā)展,但總體看來,技術(shù)水平仍比工業(yè)發(fā)達(dá)國家要落后15—20年,這與我國制造業(yè)發(fā)展的要求相比差距還很大。為了推進(jìn)社會主義現(xiàn)代化建設(shè),適應(yīng)國民經(jīng)濟(jì)各部門發(fā)展的需要,模具工業(yè)需要進(jìn)行進(jìn)一步技術(shù)結(jié)構(gòu)和加速國產(chǎn)化。因此,應(yīng)立足國情,著重發(fā)展模具行業(yè)中的關(guān)鍵、共性技術(shù).不斷加大新技術(shù)的開發(fā)和推廣應(yīng)用力度,不斷提高行業(yè)的自主創(chuàng)新能力,用信息技術(shù)帶動和提升模具工業(yè)的制造技術(shù)水平,積極采用高新技術(shù)和先進(jìn)適用技術(shù)來提高行業(yè)的總體水平。使我國模具行業(yè)向大型、精密、復(fù)雜、高效、長壽命和多功能方向發(fā)展。推動我國模具工業(yè)技術(shù)進(jìn)步再上新臺階,將是我國模具行業(yè)發(fā)展的一個重要任務(wù)。附錄BDevelopment of cold stamping die Mold is an integral part of hightech industry is an important foundation for industrial production equipment. Produced by mold, the mold is often worth its valueseveral times. Mold Technology is a technology based on integrated technology, precision equipment, strong technology, involving new technologies, new processes, new materials, new equipment development and application. Metallurgy, materials, measurement, mechanical and electrical integration, puter and other subjects as well as casting, forging, heat treatment, machining, testing, and many other types of work together to build the system the mold products with high efficiency, low consumption, high consistency, precision and high plexity of features, this is in any other manufacturing methods can not reach. At present, the mold manufacturing industry has bee a hightech industries rely on each other with the industry, mold The level of industrial technology has bee an important measure of national manufacturing level one of the signs. Of any country, manufacturing industry is the level of overall national strength and technical expression. The mold industry is the foundation and key manufacturing industries. In response, the state has adopted corresponding policies, are actively developing mold making industry. I. Die with a long history of industrial Cold stamping process in China has a long history. According to historical records: the working people as far away as China discovered the Bronze Age with the hammering deformation properties of the metal, to the Warring States Period (403 BC, a former 221) has been refining the sword can be ancestors 2,300 years ago has acquired weapons and various metal hammering modity technology. During the long period of feudal society, our working people in the gold, silver, copper ornaments, and the production of daily necessities, but also shows sophisticated superb artistic level, it is amazing. In modern times, from the last century 2039。s, metal products, toys and hardware and other industries began using punch presses and other simple mechanical devices and the corresponding product of the rough mold or some parts, one of the knifeedge mold specialized for punching, dock workers mold can be used for metal extension. Relatively low in productivity, technology is not enough. At that time stamping equipment used in power plants is not large, or even most of the pedal or lever. Mold processing industry mainly manual and therefore the accuracy of the mold is not high, the failure rate of large. Until the early 20th century, 40, appeared hydraulic Die. 50 years after the publicprivate partnerships. Added a grinding, milling and sawing equipment, and coupled with hardness, diameter and inner diameter measuring device such as a more precise gauge block measuring equipment, Die precision can be improved. The sixties and seventies, with the production of largescale use stamping machine, Die single dashed from the original material, the development of a single punching die punching pound die. Die frame and because the emergence of standard parts, so that the mold design of structural forms, which also increase the accuracy. At the same time. With the progress of heat treatment technology and testing means perfect, Die service life 5 to 7 times. This period. Also due to form grinding, wire cutting machine tools and other electrical pulse, and have to use, and alloy for mold materials used, production of Die a new development process. Designers to improve the modeling process, with automatic feeding, automatic feeding device management chip and then the posite die in large numbers. After the introduction by the milling machine model, plaster, mold, or surgery can be reproduced the same physical shape of the mold core, so that the production of mold pound to facilitate deep care a lot, to ensure accuracy. 70 years later, using the slope Die Cutting processing. The punch (punch) and die cutting can be quenched and then assembled to replace the original production of Die Deformation need treatment for a correction of a plicated assembly process, the mold precision can reach . Can be said that this time the rapid development of China39。s mo
