国外对于大量生产的工件,大都采用高效率模具,如多工序多件、自动或半自动;对新产品試制或小批生产的零件,則采用各种不同形式的简易模具。在模具制造方面,广泛采用高效率高精度的专用机床,大量应用磨削,并不断探索和使用新工艺,如电加工、化学加工等特种技术:还利用新材料来制造模具,例如用塑料制造拉深模、弯模,以降低成本。在生产組織上,建立了不少集中生产模具与模具标准件的专业厂,以提高效率、縮短周期。本文根据作者为1964年上海市模具先进經驗交流会議編写的資料,和在“板料冲压与自动化”地区性学术会議上的讲稿,删去与本刊1963年5月号“国外冲压技术发展的若干方面”一文的重复部分,整理而成,就模具結构、模具新材料及模具制造三个方面对国外情况作一些介紹。
Foreign for mass production of the workpiece, most of the high-efficiency mold, such as multi-process more than one, automatic or semi-automatic; new product trial or small batch production parts, the use of various forms of simple mold. In the mold manufacturing, extensive use of high efficiency and precision machine tools, a large number of application of grinding, and continue to explore and use of new technologies, such as electrical processing, chemical processing and other special technologies: the use of new materials to manufacture molds, such as plastic Draw deep mold, bending mold, to reduce costs. In the production organization, the establishment of a lot of focus on the production of mold and die standard parts professional factory, in order to improve efficiency and shorten the cycle. This article according to the author for the 1964 Shanghai mold advanced experience exchange meeting prepared by the materials, and in the “sheet metal stamping and automation” regional academic conference speech, delete with the magazine May 1963 “foreign stamping technology development Some aspects of the article, ”a repeat of the article, compiled from the mold structure, new mold materials and mold manufacturing three aspects of the foreign situation to make some introduction.
