【正文】 模具上的易損件應(yīng)容易更換。另有將落料、彎曲、拉深、沖孔和切邊等多工序安排在一個模具的不同工位上,在沖壓過程中坯料依次通過多工位被連續(xù)沖壓成形,至最后工位成為制件,這種模具稱為級進(jìn)模,又稱連續(xù)模。這種模具應(yīng)用普遍,結(jié)構(gòu)簡單,制造容易,但生產(chǎn)效率低。成形用的模具有型腔,分離用的模具有刃口。用于加工非金屬和粉末冶金的模具,則按加工對象命名和分類,有塑料模、橡膠模和粉末冶金模等。模具除其本身外,還需要模座、模架、導(dǎo)向裝置和制件項(xiàng)出裝置等,這些部件一般都是制成通用型,以適用于一定范圍的不同模具。分開時裝入坯料或取出制件,合攏時使制件與坯料分離或成形。因此,模具生產(chǎn)的水平是機(jī)械制造水平的重要標(biāo)志之一。模具基本上是單件生產(chǎn)的,其形狀復(fù)雜,對結(jié)構(gòu)強(qiáng)度、剛度、表面硬度、表面粗糙度和加工精度都有很高的要求,所以模具生產(chǎn)需要有很高的技術(shù)水平。關(guān)鍵詞:支板,沖壓工藝,復(fù)合模Ramming craft mold structural design Written by Li Chang longSupervised by Sun YongAbstract:This paper is onboard process of stamping die structure design, including punching and blanking two basic processes. According to parts sizes and shapes and materials requested selection of flipdie, who used part of an edge straight to the value of the layout. With two die, two onetime dropexpected, no flip expected to plete all of the punching. Direct result of the layout, the two parts on the centersymmetry, the module handles Design Center is the symmetry of the two die Centre. Block the adoption of side edge device, the step to ensure accuracy. Based on th
