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.精密沖裁模簡(jiǎn)介：精沖是一種鈑金加工技術(shù)。由于高精度、完美和平滑的切割表面，它允許制造現(xiàn)成的功能部件。該工藝是基于三效壓力機(jī)、特殊材料和模具的組合。這提供了幾個(gè)優(yōu)點(diǎn)，如低平坦度值，沖壓表面硬化和高角精度。此外，該技術(shù)允許非常厚的(1至15mm)金屬的沖裁、彎曲、上漿、拉伸和成形其他三維幾何形狀以及其他復(fù)雜輪廓，具有高精度。歷史：因此，該技術(shù)可以應(yīng)用于許多領(lǐng)域，其中需要大規(guī)模生產(chǎn)高性能金屬部件。1923年初，德國(guó)的Shiess先生發(fā)明了精密沖裁技術(shù)，但這項(xiàng)技術(shù)當(dāng)時(shí)純粹地秘密地應(yīng)用于鐘表行業(yè)。到1950年底，生產(chǎn)了精沖壓力機(jī)，并公布了該技術(shù)。1960年初，該技術(shù)的應(yīng)用范圍從鐘表工業(yè)擴(kuò)展到輕工業(yè)，也從西方國(guó)家擴(kuò)展到東方國(guó)家。在1980，世界上有超過(guò)2800套精沖壓力機(jī)。原理：與精沖工藝相比，常規(guī)沖壓工藝中沖頭與模具之間的間隙較大，如圖4-1所示。此外，沒(méi)有轉(zhuǎn)向力和反作用。結(jié)果表明，常規(guī)沖壓成形的零件具有約1/3的剪切刃，其形狀是彎曲的，而精沖成形的零件具有100%的剪切刃、平坦的形狀和精確的尺寸。此外，在應(yīng)用精密沖裁技術(shù)中，沖頭與模具之間的間隙要小得多，如圖4-2所示，以及施加的轉(zhuǎn)向和反作用力。常規(guī)沖壓：如果你還了解傳統(tǒng)金屬?zèng)_壓，那么精沖更容易理解。首先要記住的是，所有金屬都具有特定的彈性行為。在常規(guī)沖壓過(guò)程中，金屬在初始沖頭接觸時(shí)變形。圖4-3示出了在一塊金屬板上穿孔或切割孔的第一步。當(dāng)沖頭與板接觸時(shí)，金屬開(kāi)始變形并圍繞凸模的尖端鼓起。當(dāng)零件材料的屈服強(qiáng)度被壓力機(jī)的向下力超過(guò)時(shí)，沖頭的尖端開(kāi)始穿透金屬表面。優(yōu)勢(shì)：采用精密沖裁工藝，零件的顯著改進(jìn)明顯。由于這些部件具有良好的形狀、光滑的表面和精確的尺寸，它們可以隨時(shí)進(jìn)行組裝，而無(wú)需任何進(jìn)一步的二次操作。生產(chǎn)率提高，生產(chǎn)周期時(shí)間和部件成本顯著降低。設(shè)備：采用精沖的特殊結(jié)構(gòu)的模具，沖壓產(chǎn)品的生產(chǎn)，如圖4和圖5所示。應(yīng)用：精密沖裁技術(shù)已廣泛應(yīng)用于門鎖、齒輪箱、斜靠座調(diào)節(jié)器等汽車工業(yè)。如果你不需要沖壓到嚴(yán)格的公差，不要求表面光滑，也不需要執(zhí)行大量的二次操作，精沖就不適合你。還應(yīng)當(dāng)指出，沖程速率不接近那些傳統(tǒng)沖壓機(jī)的沖程速率。但是如果您需要嚴(yán)格的公差和耗時(shí)耗錢的二次操作，那么精沖裁絕對(duì)值得一看。理解綜述（不少于800字）一、本文主要內(nèi)容精沖這一技術(shù)原本是德國(guó)的shiess先生發(fā)明純粹應(yīng)用于鐘表行業(yè)的，后來(lái)生產(chǎn)了精沖壓力機(jī)，并公布了該技術(shù)。該技術(shù)的應(yīng)用范圍從鐘表工業(yè)擴(kuò)展到輕工業(yè)，也從西方國(guó)家擴(kuò)展到東方國(guó)家。在1980，世界上有超過(guò)2800套精沖壓力機(jī)。精沖工藝是基于三效壓力機(jī)、特殊材料和模具的組合，是一種具有低平坦度值，沖壓表面硬化和高角精度的鈑金加工技術(shù)。 該技術(shù)可允許厚度達(dá)1-15毫米材料沖裁、彎曲、上漿、拉伸和成形其他三維幾何形狀以及其他復(fù)雜輪廓，并且具有高精度，100%的剪切刃、平坦的形狀和精確的尺寸。此外，在應(yīng)用精密沖裁技術(shù)中，沖頭與模具之間的間隙要小得多。它的原理是在一塊金屬板上穿孔或切割孔的第一步，當(dāng)沖頭與板接觸時(shí)，金屬開(kāi)始變形并圍繞凸模的尖端鼓起。當(dāng)零件材料的屈服強(qiáng)度被壓力機(jī)的向下力超過(guò)時(shí)，沖頭的尖端開(kāi)始穿透金屬表面。它的優(yōu)勢(shì)是精沖加工出來(lái)的部件具有良好的形狀、光滑的表面和精確的尺寸，它們可以隨時(shí)進(jìn)行組裝，而無(wú)需任何進(jìn)一步的二次操作。生產(chǎn)率提高，生產(chǎn)周期時(shí)間和部件成本顯著降低。如果你所需要的工件需要嚴(yán)格的公差，且表面光滑，精沖是你不二的選擇。2、 本文主要研究方法（手段）1）文獻(xiàn)閱讀法。通過(guò)網(wǎng)絡(luò)資源、高校圖書(shū)館網(wǎng)絡(luò)數(shù)據(jù)庫(kù)資源、校
