E 型片畢業(yè)論文設(shè)計(jì) 1 E 型片復(fù)合模具設(shè)計(jì) 摘 要：本設(shè)計(jì)為一 E 型片的冷沖壓模具設(shè)計(jì)，根據(jù)設(shè)計(jì)零件的尺寸、材料、批 量生產(chǎn)等要求，首先分析零件的工藝性，確定沖裁工藝方案及模具結(jié)構(gòu)方案，然后通過(guò)工 藝設(shè)計(jì)計(jì)算，確定排樣和裁板，計(jì)算沖壓力和壓力中心，初選壓力機(jī)，計(jì)算凸、凹模刃口 尺寸和公差，最后設(shè)計(jì)選用零、部件，對(duì)壓力機(jī)進(jìn)行校核，繪制模具總裝草圖，以及對(duì)模 具主要零件的加工工藝規(guī)程進(jìn)行編制。其中在結(jié)構(gòu)設(shè)計(jì)中，主要對(duì)凸模、凹模、凸凹模、 定位零件、卸料與出件裝置、模架、沖壓設(shè)備、緊固件等進(jìn)行了設(shè)計(jì)，對(duì)于部分零部件選 用的是標(biāo)準(zhǔn)件，就沒(méi)深入設(shè)計(jì)，并且在結(jié)構(gòu)設(shè)計(jì)的同時(shí)，對(duì)部分零部件進(jìn)行了加工工藝分 析，最終才完成這篇畢業(yè)設(shè)計(jì)。 關(guān)鍵詞：模具；沖裁件；凸模；凹模；凸凹模； E 型片畢業(yè)論文設(shè)計(jì) 2 Abstract: The design for E-type film of cold stamping die design, according to the size of the design components, materials, production requirements, the first part of the process of determining blanking die structure of the programme and the programme, and then through the design process, Determine layout and the Conference Board, and the calculation of the pressure-pressure center, the primary presses, calculated convex and concave-edge size and tolerance, the final design is selected, components, to check on the press, assembly and drawing the draft die, and Die major parts of the processing technology for the preparation of a point of order. In the design of the structure, mainly on punch, die, die Tuao, positioning parts, and the unloading of the device, model planes, stamping equipment, such as fasteners for the design, selection of some parts of the standard parts , There is no in-depth design, structural design and in the meantime, some parts of the processing technology for the analysis and eventually graduate to complete this design. Key words: Die; blanking pieces; punch; die; Tuao die; E 型片畢業(yè)論文設(shè)計(jì) 3 目錄 摘 要
