沖壓工藝外文文獻

1、Characteristics and Sheet Metal Forming1 The article overview Stamping is a kind of plastic forming process in which a part is produced by means of the plastic forming the material under the action of a die. Stamping is usually carried out under cold state, so it is also called stamping. Heat stamping is used only when the blank thickness is greater than 8100mm. The blank material for stamping is usually in the form of sheet or strip, and therefore it is also called sheet metal forming. Some n。

3、附錄 1 外文譯文 第八章 沖壓變形 沖壓變形工藝可完成多種工序，其基本工序可分為分離工序和變形工序兩大類。 分離工序是使坯料的一部分與另一部分相互分離的工藝方法，主要有落料、沖孔、切邊、剖切、修整等。其中有以沖孔、落料應(yīng)用最廣。變形工序是使坯料的一部分相對另一部分產(chǎn)生位移而不破裂的工藝方法，主要有拉深、彎曲、局部成形、脹形、翻邊、縮徑、校形、旋壓等。 從本質(zhì)上看，沖壓成形就是毛坯的變形區(qū)在外力的作用下產(chǎn)生相應(yīng)的塑性變形，所以變形區(qū)的應(yīng)力狀態(tài)和變形性質(zhì)是決定沖壓成形性質(zhì)的基本因素。因此，根據(jù)變形區(qū)應(yīng)力狀。

6、英文文獻翻譯翻譯原文題目：I Reading A The Fine Blanking TechnologyIntroductionFine blanking is a sheet metal machining technology. It allows manufacturing ready-to-use functional components thanks to high-precision, perfectly and smoothly cut surfaces.The process is based on the combination of triple-acting presses, special materials and dies. This offers several advantages, such as low flatness values, hardening of blanked surfaces and high angular precision.Furthermore, this technology allows 。
