英文文献翻译翻译原文题目：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 blanking of very thick (1 to 15 mm) metals, bending, sizing, drawing and shaping of other three-dimensional geometric forms as well as other complex profiles, with high accuracy.This technology can therefore be applied to many fields, where there is a need to mass-produce high-performance metal components.HistoryIn the early 1923, the fine blanking technology was invented by Mr. Schiess in Germany. However, this technology was purely and secretly applied in Watch industry at that time. Until the 1950, the fine blanking press was produced and the technology had been published. In the earlier 1960, the application of the technology was extended from the watch industry to the light industries; also from Western countries to Eastern countries. From the 1970, this technology had been widely applied from Light industries to Heavy industries. In 1980, there were over 2800 sets of the Fine-Blanking Presses in the world.PrincipleCompared with the fine blanking, the clearance between the punch and the die is larger in the Conventional Stamping as shown in Figure 4-1. In addition, there are no veering force and counter force. As a result, the components produced by the Conventional Stamping are found to have about 1/3 shearing edge and their shape is bowed whilst those produced by the fine blanking are found to have 100% shearing edge, flat shape and accurate dimensions. Furthermore, in applying the Fine-Blanking Technology, the clearance between the punch and the die is much smaller, as shown in Figure 4-2, together with the imposed veering and counter forces.triPunch ForceFigure 4-3Conventional PunchingFine blanking is easier to understand if you also understand what takes place during conventional metal punching.The first thing to remember is that all metals have a particular elastic behavior. During conventional punching, the metal deforms upon initial punch contact. Figure 4-3 shows the first step in piercing or cutting a hole in a piece of sheet metal.When the punch makes contact with the sheet, the metal begins to deform and bulge around the point of the punch. As the yield strength of the part material is exceeded by the downward force of the press, the point of the punch begins to penetrate the metals surface.AdvantagesBy applying the fine blanking technology, the significant improvement of the component should be obvious. As the components are with good shape, smooth surface and precise size, they can be ready for assembly without any further secondary operations. The productivity is increased, the production cycle time and Figure 4-4 Hydraulic Press Figure 4-5 Tools and Diethe component cost are significantly reduced.EquipmentUsing the fine blanked presses with the special construction die, fine blanked products can be produced effectively, as shown in Figure 4 and 5.ApplicationThe fine blanking has been used in the automotive industry such as door locks, gear boxes, reclining seat adjusters, etc. Furthermore, the fine blanking can also be applied to electronic and electrical industry.Fine blanking is not for you if you dons need to stamp to tight tolerances, dons require smooth surfaces and dons perform extensive secondary operations. It also should be noted that stroke rates do not approach those of conventional stamping presses. But if you need tight tolerances and tire of time- and cash-consuming secondary operations, then fine blanking is definitely worth a look.NotesIt allows manufacturing ready-to-use functional components thanks to high-precision, perfectly and smoothly cut surfaces.句子中的 thanks to 是一个副词短语，可译成“由于”；全文可译为：由于能够完美自如，且高精度地切割表面，这项技术可以制造出随时可以使用的功能性零部件。Fine blanking is not for you if you dont need to stamp to tight tolerances, dont require smooth surfaces and dont perform extensive secondary operations.本句中“dont need to.，dont require.和 dont perform.”为并列结构；全文可译为：如果您不需要冲压实现紧密公差、不需要光滑的表面以及不需要执行广泛的二次操作，那就无需精冲了。New wordsfunctional fAfkJanl adj.功 能 的component kampaunant n.零 件high-precision haiprsi3ann.髙精度，高精密度fine fain a.精 密 的blank blaeqk v.冲 裁diedain.模具，凹模machine m9J“i:n v.力口工manufacture maenjufaektj a v.制造ready-to-use Yeditu: ju:s a随时可以使用的functional fAikJanl a.功 能 的component kampaunant n 零 部 件precision prisi3an n.精 度cut kAt v.切 割surface sa:fis n.表 面combination .kombineij an n.组 合press pres n.flatness flaetnis n.水 平hardening .ha:danir n.硬 化angular aergjula a 角 的bend bend v.弯 曲size saiz v.精 压draw dro: v.拉 伸shape Jeip v.成 形 翻译正文：精冲工艺介绍精冲是一种板料加工技术。高精密、完美、平滑的切割表面，使其能够制造出随时可用的功能部件。该工艺是由三作用冲床、特殊材料和模具组合而成。这提供了几个优点，如低平整度值，淬火的毛坯表面和高的空腔精度。此外，该技术还允许对非常厚(1 - 15mm)的金属进行冲裁、弯曲、上浆、绘制和成型其他三维几何形状以及其他复杂的型材，具有较高的精度。因此，该技术可以应用于许多领域，这些领域需要大量生产高性能的金属部件。历史1923 年初，德国的 Schiess 先生发明了精细冲裁技术。然而，这一技术在当时的钟表行业是纯粹且秘密的应用。直到 1950 年，精冲裁机问世，该技术才得以发表。1960 年代初，该技术的应用范围从手表行业扩展到轻工业;也从西方国家到东方国家。从 1970 年开始，这项技术被广泛应用于从轻工业到重工业。1980 年，世界上有 2800 多台精密冲裁机。原则与精冲相比，传统冲压中冲床与模具间隙较大，如图 4-1 所示。此外，没有转向力和反作用力。结果发现，常规冲压生产的零件约有 1/3 的剪切边，且形状呈弓形，而精冲生产的零件则 100%剪切边，形状平整，尺寸准确。此外，在采用精冲工艺时，冲头与模具之间的间隙要小得多，如图 4-2 所示，外加转向力和反作用力。传统的冲压如果你也了解在传统的金属冲压过程中发生了什么，那么精冲更容易理解。首先要记住的是所有的金属都有一个特殊的弹性行为。在常规冲孔过程中，金属在初始冲孔接触时会发生变形。图 4-3 显示了在一片金属片上穿孔或切割一个孔的第一步。当冲头与板材接触时，金属开始变形并在冲头周围凸起。当零件材料的屈服强度被压力机向下的力超过时，冲头的尖端开始穿透金属表面。优势采用精冲工艺，可明显改善零件的性能。该零件形状好，表面光滑，尺寸精确，无需二次加工即可组装。提高了生产效率，大大缩短了生产周期，降低了零部件成本。设备采用特殊结构模具的精冲冲床，可有效生产精冲制品，如图 4、5 所示。应用精冲在汽车门锁、变速箱、躺椅调整器等行业中有广泛的应用，也可应用于电子、电气等行业。如果您不需要压印到紧公差，不需要光滑的表面，也不需要进行大量的二次加工，那么精冲就不适合您。还应注意的是冲程率不接近传统冲床的冲程率。但如果你需要严格的公差和厌倦了耗时耗钱的二次操作，那么精冲绝对值得一看。笔记It allows manufacturing ready-to-use functional components thanks to high-precision, perfectly and smoothly cut surfaces.句子中的thanks to 是一个副词短语，可译成“由于”；全文可译为：由于能够完美自如，且高精度地切割表面，这项技术可以制造出随时可以使用的功能性零部件。Fine blanking is not for you if you dont need to stamp to tight tolerances, dont require smooth surfaces and dont perform extensive secondary operations.本句中“dont need to.，dont require.和 dont perform.”为并列结构；全文可译为：如果您不需要冲压实现紧密公差、不需要光滑的表面以及不需要执行广泛的二次操作，那就无需精冲了。新的单词functional fAfkJanl adj.功 能 的component kampaunant n.零 件high-precision haiprsi3ann.髙精度，高精密度fine fain a.精 密 的blank blaeqk v.冲 裁diedain.模具，凹模machine m9J“i:n v.力口工manufacture maenjufaektj a v.制造ready-to-use Yeditu: ju:s a随时可以使用的functional fAikJanl a.功 能 的component kampaunant n 零 部 件precision prisi3an n.精 度cut kAt v.切 割surface sa:fis n.表 面combination .kombineij an n.组 合press pres n.flatness flaetnis n.水 平hardening .ha:danir n.硬 化angular aergjula a 角 的bend bend v.弯 曲size saiz v.精 压draw dro: v.拉 伸shape Jeip v.成 形 理解综述一、本文主要内容精冲是一种板料加工技术。高精密、完美、平滑的切割表面，使其能够制造出随时可用的功能部件。精冲是一种板料加工技术。高精密、完美、平滑的切割表面，使其能够制造出随时可用的功能部件。1923 年初，德国的 Schiess先生发明了精细冲裁技术。与精冲相比，传统冲压中冲床与模具间隙较大。此外，没有转向力和反作用力。精冲在汽车门锁、变速箱、躺椅调整器等行业中有广泛的应用，也可应用于电子、电气等行业。2、本文主要研究方法（手段）1. 网上资料的查询.2. 刘彦国老师的指导3. 图书馆文献的阅览3、本文主要结论精冲是一种板料加工技术。高精密、完美、平滑的切割表面，使其能够制造出随时可用的功能部件。该工艺是由三作用冲床、特殊材料和模具组合而成。这提供了几个优点，如低平整度值，淬火的毛坯表面和高的空腔精度。此外，该技术还允许对非常厚(1 - 15mm)的金属进行冲裁、弯曲、上浆、绘制和成型其他三维几何形状以及其他复杂的型材，具有较高的精度。因此，该技术可以应用于许多领域，这些领域需要大量生产高性能的金属部件。
