【正文】 水 杯結(jié)構(gòu)尺寸圖 精度與表面粗糙度要求 要滿足在 IT13 級(jí)以下，不宜高于 IT11。 （ 2）杯子外筒的尺寸設(shè)計(jì)為高為 165mm、直徑為 64mm、厚度為 1mm。 （ 3） 由于拉伸件的變形程度有所限制拉伸件可能要進(jìn)行幾次拉伸才能獲得所需尺寸的零件。 材料的經(jīng)濟(jì)效益 水杯是人們生活中普遍使用 的喝水容器，所以要求它的材料有耐腐蝕耐磨性，使用壽命也要保證，所以從經(jīng)濟(jì)和材料的性能出發(fā)，杯子的材料選擇 304 不銹鋼。 (3)材料具有符合我們要求的硬度，材料所有面積和長(zhǎng)度均勻一致。 基本步驟 (1)工藝的設(shè)計(jì) 首先我們根據(jù)所要設(shè)計(jì)的零件的形狀、尺寸進(jìn)行分析，確定工藝方案，進(jìn)行毛坯的計(jì)算、材料利用率和壓力機(jī)的噸位的校核。使用計(jì)算機(jī)繪圖，使生產(chǎn)周期和精度都大大提高，提高了生產(chǎn)效率，促使模具向前發(fā)展。由于模具制造一直被視為生產(chǎn)后方 ,我國(guó)的模具發(fā)展一直很緩慢 ,1984年成立了模具工業(yè)協(xié)會(huì) ,1987年模具首次被列入機(jī)電產(chǎn)品目錄 ,當(dāng)時(shí)全國(guó)共有 6000家模具生產(chǎn)制造廠點(diǎn)。 (3)沖壓時(shí)一般很少產(chǎn)生碎料，材料利用率高，在加工過程中也不需要其它加熱設(shè)備，所以是一種高效節(jié)能的加工工藝 [8]。s living standards, people also have a higher demand for cups , the cup is no longer a simple water containing apparatus, and need it to the multifunction, a more healthy direction of development. Therefore, its material requirements, heat resistance and corrosion and environmental protection, the function of its requirements for better insulation effect, the appearance of simple and elegant. The stainless steel cup design not only exercise me have a good understanding of the market, on the other hand exercise my skilles that using Auto CAD drawing software. It improve me in the mould design, mould material, mould injection molding process analysis and data retrieval and improving access to prehensive training, summarizes and master the rules and methods of die my future and lay a solid foundation. The main contents of the design include: (1) This paper describes the development status and development advantages of stamping II die at home and abroad, the purpose and significance of stamping die research. (2) The machining process of the parts is analyzed and the relevant dimensions are calculated. (3) Mold design, mainly for the choice of the press, fall material drawing convex, concave die size calculation, mold selection, positioning device, unloading feeding device of choice. (4) The problem encountered during the stretching is both the solution and the auxiliary process. (5) The final drawing of the mold assembly drawings and parts diagram.
