端 罩 的 沖 壓 成 形 工 藝 及 沖 壓 模 具 設(shè) 計(jì) 摘要 本設(shè)計(jì)題目為端罩的設(shè)計(jì) 體現(xiàn)了深薄壁類零件的設(shè)計(jì)要求 內(nèi)容及方向 有 一定的設(shè)計(jì)意義 通過對(duì)該零件模具的設(shè)計(jì) 進(jìn)一步加強(qiáng)了設(shè)計(jì)者冷沖模設(shè)計(jì)的基礎(chǔ) 知識(shí) 為設(shè)計(jì)更復(fù)雜的冷沖模具做好了鋪墊和吸取了更深刻的經(jīng)驗(yàn) 本設(shè)計(jì)運(yùn)用薄板類零件成型工藝及模具設(shè)計(jì)的基礎(chǔ)知識(shí) 首先分析了零件的成分 及性能要求 為設(shè)計(jì)拉深及沖裁模的數(shù)據(jù)指標(biāo)做好了準(zhǔn)備 然后計(jì)算了零件的體積 便于設(shè)計(jì)落料模的刃口尺寸 最后設(shè)計(jì)了模具的結(jié)構(gòu)特征 確定了模具的設(shè)計(jì)參數(shù) 設(shè)計(jì)要點(diǎn)及推出裝置的設(shè)計(jì) 沖壓加工分為分離工序和成形工序兩大類 落料 打孔屬于分離工序 拉深屬于 成形工序 設(shè)計(jì)任務(wù)是指導(dǎo)老師指定加工的零件為有孔拉深件 材料為鋁 L3 厚度為 2mm 大批量生產(chǎn) 其他具體要求參照零件圖 根據(jù)零件形狀 需要采用落料 拉深 沖孔 3 個(gè)工序 為提高成倍提高生產(chǎn)效率 提高沖壓件的質(zhì)量 可采用落料和拉深過 程集中于一套模具來(lái)完成 沖孔工序用簡(jiǎn)單模完成 關(guān)鍵詞 落料 拉深 沖孔 The drop cylinder shaped pieces of material drawing punching trimming the compound die design Abstract The design of the sets of topics for the long injection mold design reflects the deep thin wall plastic parts of the design content and direction of a certain design significance Parts of the mold through the design the designer has been further strengthened by the injection mold design based on knowledge for the design of more complex injection molds made and lessons foreshadowing a more profound experience The use of thin design parts molding process and die design of the basic knowledge first of all parts of the composition and performance requirements for the design and drawing Die data prepared for the target and then calculate the size of the parts for design Blanking the edge size final design of the structure of the mold a mold determine the design parameters design elements and the introduction of the device design Cutting and piercing belong to separating pulling and stretching belong to calendering The spare parts fall to cut material pull and stretch compound die and multiple hole punched die to process The job is in order to process the multiple hole punched die and pull stretch die design which is given by the tutor the material is AL L3 the thickness is a 2 mm the large quantity quantity produce other request to according to the spare parts diagram in a specific way According to the spare parts shape it need to to cut material to pull and stretch to punched hole 3 work become for the exaltation to raise the production efficiency doubly raise to the quantity of part to cut material and to pull and stretch adopt to compound die to complete to punched hole adopt to pierce die to complete Keywords cut material pull and stretch piercing
