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 highAngular precisionFurthermore, 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. 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.Conventional PunchingFine blanking is easier to understand if you also understand what takes places 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 metal s 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 the 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 dont need to stamp to tight tolerances, dont require smooth surfaces and dont 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.精密冲裁模简介：精冲是一种钣金加工技术。由于高精度、完美和平滑的切割表面，它允许制造现成的功能部件。该工艺是基于三效压力机、特殊材料和模具的组合。这提供了几个优点，如低平坦度值，冲压表面硬化和高角精度。此外，该技术允许非常厚的(1 至 15mm)金属的冲裁、弯曲、上浆、拉伸和成形其他三维几何形状以及其他复杂轮廓，具有高精度。历史：因此，该技术可以应用于许多领域，其中需要大规模生产高性能金属部件。1923 年初，德国的 Shiess 先生发明了精密冲裁技术，但这项技术当时纯粹地秘密地应用于钟表行业。到 1950 年底，生产了精冲压力机，并公布了该技术。1960 年初，该技术的应用范围从钟表工业扩展到轻工业，也从西方国家扩展到东方国家。在 1980，世界上有超过 2800 套精冲压力机。原理：与精冲工艺相比，常规冲压工艺中冲头与模具之间的间隙较大，如图 4-1所示。此外，没有转向力和反作用。结果表明，常规冲压成形的零件具有约1/3 的剪切刃，其形状是弯曲的，而精冲成形的零件具有 100%的剪切刃、平坦的形状和精确的尺寸。此外，在应用精密冲裁技术中，冲头与模具之间的间隙要小得多，如图 4-2 所示，以及施加的转向和反作用力。常规冲压：如果你还了解传统金属冲压，那么精冲更容易理解。首先要记住的是，所有金属都具有特定的弹性行为。在常规冲压过程中，金属在初始冲头接触时变形。图 4-3 示出了在一块金属板上穿孔或切割孔的第一步。当冲头与板接触时，金属开始变形并围绕凸模的尖端鼓起。当零件材料的屈服强度被压力机的向下力超过时，冲头的尖端开始穿透金属表面。优势：采用精密冲裁工艺，零件的显著改进明显。由于这些部件具有良好的形状、光滑的表面和精确的尺寸，它们可以随时进行组装，而无需任何进一步的二次操作。生产率提高，生产周期时间和部件成本显著降低。设备：采用精冲的特殊结构的模具，冲压产品的生产，如图 4 和图 5 所示。应用：精密冲裁技术已广泛应用于门锁、齿轮箱、斜靠座调节器等汽车工业。如果你不需要冲压到严格的公差，不要求表面光滑，也不需要执行大量的二次操作，精冲就不适合你。还应当指出，冲程速率不接近那些传统冲压机的冲程速率。但是如果您需要严格的公差和耗时耗钱的二次操作，那么精冲裁绝对值得一看。理解综述（不少于 800 字）一、本文主要内容精冲这一技术原本是德国的 shiess 先生发明纯粹应用于钟表行业的，后来生产了精冲压力机，并公布了该技术。该技术的应用范围从钟表工业扩展到轻工业，也从西方国家扩展到东方国家。在 1980，世界上有超过 2800 套精冲压力机。精冲工艺是基于三效压力机、特殊材料和模具的组合，是一种具有低平坦度值，冲压表面硬化和高角精度的钣金加工技术。 该技术可允许厚度达 1-15毫米材料冲裁、弯曲、上浆、拉伸和成形其他三维几何形状以及其他复杂轮廓，并且具有高精度，100%的剪切刃、平坦的形状和精确的尺寸。此外，在应用精密冲裁技术中，冲头与模具之间的间隙要小得多。它的原理是在一块金属板上穿孔或切割孔的第一步，当冲头与板接触时，金属开始变形并围绕凸模的尖端鼓起。当零件材料的屈服强度被压力机的向下力超过时，冲头的尖端开始穿透金属表面。它的优势是精冲加工出来的部件具有良好的形状、光滑的表面和精确的尺寸，它们可以随时进行组装，而无需任何进一步的二次操作。生产率提高，生产周期时间和部件成本显著降低。如果你所需要的工件需要严格的公差，且表面光滑，精冲是你不二的选择。2、本文主要研究方法（手段）1）文献阅读法。通过网络资源、高校图书馆网络数据库资源、校图书馆馆藏图书等方式，获得与研究课题相关的文献资料。2）调查法3、本文主要结论精密冲裁技术应用广泛，是一种基于三效压力机、特殊材料和模具的组合，是一种具有低平坦度值，冲压表面硬化和高角精度的钣金加工技术。可用于材料的冲裁、弯曲、上浆、拉伸和成形其他三维几何形状以及其他复杂轮廓的加工。相比于传统的冲压工艺，精密冲裁技术的精度更精确，比起传统冲压工艺的 1/3 的剪切刃，精冲具有 100%的剪切刃，冲头与模具之间的间隙小，加工出来的工件尺寸精度高，形状良好，表面光滑，组装的精度也随之准确，减少装配误差，且生产周期时间和部件成本显著降低。随着技术的不断提高，精密冲裁模将应用于更广泛的领域。
