介绍《精冲技术》近二十多年来迅速发展的概况。从《精冲技术》发明至今的六十多年中,前35年在秘密状态下仅在钟表及类似薄小零件精冲方面有些断续发展。1958年后随着精冲技术公诸于世、相关基础技术的发展,精冲技术得到普及。本文介绍了精冲技术的发展过程、近年来开发精冲及与之间相关的材料、模具、设备和润滑等技术取得的进展,当前的主要发展动向及已经达到的工艺水平。
Introducing the “fine blanking technology” in the past two decades the rapid development of the overview. In the sixty years since the invention of “fine blanking technology”, the first 35 years have only been intermittently developed in the secret state in the fine blanking of clocks and similar thin parts. After 1958 fine blanking technology made public, related to the development of basic technology, fine blanking technology has been popularized. This article describes the development of fine blanking technology. In recent years, developments in fine blanking and related materials, molds, equipment and lubrication have been introduced, as well as the main current developments and the technological levels that have been reached.
