【正文】 I 摘 要 隨著中國(guó)經(jīng)濟(jì)的迅速發(fā)展，模具已經(jīng)成為現(xiàn)今工業(yè)生產(chǎn)不可或缺的裝備，占有著越來(lái)越重要的地位。在這樣的發(fā)展形式下選擇模具設(shè)計(jì)這樣一個(gè)有意義的是一次非常重要的鍛煉機(jī)會(huì)。 沖壓是機(jī)械制造中先進(jìn)的加工方法之一，它利用壓力機(jī)通過(guò)模具對(duì)板料加壓，使其產(chǎn)生塑性變形或者分離，從而獲得一定形狀、尺寸和性能的零件。沖壓的主要設(shè)備是沖床和沖裁模具。 經(jīng)過(guò)查閱資料，首先要對(duì)零件進(jìn)行工藝分析，經(jīng)過(guò)工藝分析和對(duì)比，采用沖孔落料工序，通過(guò)沖裁力、頂件力、卸料力等計(jì)算，確定壓力機(jī)的型號(hào)。 再分 析對(duì)沖壓件加工的模具適用類(lèi)型選擇所需設(shè)計(jì)的模具 。 得出將設(shè)計(jì) 模具類(lèi)型后將模具的各工作零部件設(shè)計(jì)過(guò)程表達(dá)出來(lái)。 在模具設(shè)計(jì)當(dāng)中，產(chǎn)品的沖壓工藝不可能都象各種工藝的基本運(yùn)動(dòng)那樣簡(jiǎn)單，應(yīng)當(dāng)要根據(jù)具體情況對(duì)產(chǎn)品工藝作好運(yùn)動(dòng)分析，再據(jù)此作進(jìn)一步的設(shè)計(jì)。在對(duì)產(chǎn)品工藝運(yùn)動(dòng)作分析時(shí)，應(yīng)主要考慮其必要性、時(shí)間性、可行性，還應(yīng)具有創(chuàng)造性。必要性是指運(yùn)用基本運(yùn)動(dòng)原理判斷需要那些運(yùn)動(dòng)來(lái)實(shí)現(xiàn)產(chǎn)品工藝；時(shí)間性是指所需各項(xiàng)運(yùn)動(dòng)的先后順序；可行性是指能否通過(guò)結(jié)構(gòu)設(shè)計(jì)和力學(xué)設(shè)計(jì)來(lái)實(shí)現(xiàn)所需運(yùn)動(dòng)；創(chuàng)造性是指在前述運(yùn)動(dòng)無(wú)法被實(shí)現(xiàn)或運(yùn)動(dòng) 無(wú)法完全實(shí)現(xiàn)產(chǎn)品工藝的情況下，要善于大膽采用新方法去努力實(shí)現(xiàn)產(chǎn)品工藝，也就是前面所說(shuō)的對(duì)機(jī)械運(yùn)動(dòng)的靈活運(yùn)用。沖壓過(guò)程存在多種多樣的機(jī)械運(yùn)動(dòng)，而各種機(jī)械運(yùn)動(dòng)對(duì)沖壓工藝實(shí)現(xiàn)與沖壓件品質(zhì)的影響也各不相同，因而在沖壓模具設(shè)計(jì)中對(duì)機(jī)械運(yùn)動(dòng)的控制和靈活運(yùn)用對(duì)提高設(shè)計(jì)水平和保證沖壓件品質(zhì)具有重要意義。 在 論文 中第一部分，主要敘述了沖壓模具的發(fā)展?fàn)顩r，說(shuō)明了沖壓模具的重要性與本次設(shè)計(jì)的意義，接著是對(duì)沖壓件的工藝分析，完成了工藝方案的確定。第二部分，進(jìn)行沖裁工藝力的計(jì)算和沖裁模工作部分的設(shè)計(jì)計(jì)算，對(duì)選擇沖壓設(shè)備提供依 據(jù)。最后對(duì)主要零部件的設(shè)計(jì)和標(biāo)準(zhǔn)件的選 II 擇，為本次設(shè)計(jì)模具的繪制和模具的成形提供依據(jù)，以及為裝配圖各尺寸提供依據(jù)。通過(guò)前面的設(shè)計(jì)方案畫(huà)出模具各零件圖和裝配圖 再結(jié)合現(xiàn)今模具生產(chǎn)廠家的具體經(jīng)驗(yàn)進(jìn)行結(jié)構(gòu)設(shè)計(jì)，切實(shí)將設(shè)計(jì)做到能夠應(yīng)用在實(shí)際生產(chǎn)中，使模具更具有實(shí)用性。 本次設(shè)計(jì)闡述了沖壓 模 具 的結(jié)構(gòu)設(shè)計(jì)及工作過(guò)程。本模具性能可 靠，運(yùn)行平穩(wěn)，提高了產(chǎn)品質(zhì)量和生產(chǎn)效率，降低勞動(dòng)強(qiáng)度和生產(chǎn)成本 關(guān)鍵字 ： 沖壓；沖孔 ； 模具結(jié)構(gòu) III ABSTRACT With China39。s rapid economic development, mold has bee indispensable to today39。s industrial production equipment, occupy an increasingly important position. Such a development in the form of mold design to choose a meaningful way is a very important training opportunity. Stamping machinery manufacture, one of the advanced processing methods, it presses through the use of sheet metal pression mold to produce plastic deformation or separation in order to obtain a certain shape, size and performance parts. The main device is a pressing punch and stamping dies. Through access to information, the first parts to the process analysis, through process analysis and parison, the use of punch blanking process, through the blanking force, the top piece, and in terms of discharge power to determine the model press. Further analysis of the stamping dies for processing the application to select the desired type of mold design. Mold will be designed to draw upon the type of mold parts of the work expressed in the design process. In the mold design, the product of the stamping process can not have all kinds of technology as basic as a simple movement, it should be according to the specific circumstances of the product ready motion analysis technology, which further redesign. Movement of products in the analysis process should be the main consideration of its necessity, timing, feasibility, but also creative. The need for the use of basic movement is the principle to determine the needs of those campaigns to achieve product technology。 the timing of the movement refers to the order in which they required。 feasibility refers to whether the adoption of the structural design and mechanical design to achieve the required IV movement。 creativity is Movement refers to the aforementioned movement can not be achieved or not be fully realized product technology, it is necessary to be good at bold efforts to adopt a new approach to product technology, which is mentioned in front of the flexibility in the use of mechanical movement. Stamping process of a wide range of mechanical movement, and a variety of mechanical movement of the stamping process with the quality of stampings also vary, therefore the design of stamping dies for the mechanical motion control and flexibility in the use of design standards to enhance and ensure the quality stampings of great significance. In the paper the first part, mainly describes the development of stamping die, stamping die illustrate the importance and significance of this design, and then stamping parts of the process analysis, pleted a process to identify programs. The second part of blanking process for the calculation and Die Design and Calculation of the work of some of the stamping equipment to provide a basis to choose. Finally, the main ponents of standard design and the choice of designbased mapping tool and provide a basis for forming mold, as well as the assembly drawing to provide the basis of the size. Through the draw in front of mold design and assembly of the parts diagram Fig mold bined with the current manufacturer of the specific structural design experience, effective design can be used in actual production, so that a more practical tool. The design of the structure of the stamping die design and working process. Reliable performance of the mold, smooth running, improved product quality and production efficiency, reduce labor intensity and production costs Keywords: Stamping。 punching。 die structure I 目錄 摘 要 ........................................
