案②復(fù)合模結(jié)構(gòu)一般,比較容易制造。但成形制件需要兩道工序、兩套模具才能完成零件的加工,工序分散,搬運(yùn)半成品要浪費(fèi)大量時(shí)間。 ③沖孔 — 落料連續(xù)沖壓,采用級(jí)進(jìn)模生產(chǎn)。 減速器用墊片沖壓模具設(shè)計(jì) 2 對(duì)工序的安排,擬有以下幾種方案: ①落料 — 沖孔,單工序模生產(chǎn)。 ③有一定的生產(chǎn)批量,應(yīng)重視模具材料的選擇和模具結(jié)構(gòu)的確定,保證模具的壽命。(《冷沖壓工藝與模具設(shè)計(jì)》 P322) 工件精度為 IT14 級(jí),該制件形狀簡(jiǎn)單,尺寸較小,厚度一般,屬于普通沖壓件,但有幾點(diǎn)應(yīng)該注意: ①該沖裁件的材料為優(yōu)質(zhì)碳素工具鋼 10,具有較好的可沖壓性能。 punch die。 The election of press die is based on synthesis considerations on economical efficiency、 the processing property of part and plex degree iso many factors。文中還對(duì)沖壓成型零件和其它相關(guān)零件的選擇原則及選擇方法進(jìn)行了說(shuō)明,另外還介紹了幾種產(chǎn)品形狀的毛坯展開(kāi)尺寸計(jì)算的方法和簡(jiǎn)化模型,以及沖壓模具設(shè)計(jì)所需要使用的幾種參考書(shū)籍的查閱方法。 紫瑯職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計(jì) 題 目: 減速器用墊片沖壓模具設(shè)計(jì) 副 標(biāo) 題: 學(xué) 生 姓 名: 所在系、專(zhuān)業(yè): 機(jī)電工程系、模具設(shè)計(jì)與制造 班 級(jí): 模具 5091 指 導(dǎo) 教 師: 日 期: 摘 要 I 摘 要 本設(shè)計(jì)是對(duì)給定的產(chǎn)品圖進(jìn)行沖壓模具設(shè)計(jì)。沖壓工藝的選擇是經(jīng)查閱相關(guān)資料和和對(duì)產(chǎn)品形狀仔細(xì)分析的基礎(chǔ)上進(jìn)行的;沖壓模具的選擇是在綜合考慮了經(jīng)濟(jì)性、零件的沖壓工藝性以及復(fù)雜程度等諸多因素的基 礎(chǔ)上進(jìn)行的;產(chǎn)品毛坯展開(kāi)尺寸的計(jì)算是在方便建設(shè)又不影響模具成型的前提下簡(jiǎn)化為所熟悉的模型進(jìn)行的。 全套圖紙,加 153893706 關(guān)鍵詞 : 工藝、工藝性、沖壓工序、沖壓模具、尺寸 Abstract II Abstract This project is a press die designation based on the original product. The election of press process is based on consulting correlation datum and analyzing the form of manufactured product meticulous。 Calculating the work blank of manufactured product unfold dimension is lined feed on the premise of calculation convenience but without contribution die confectioning simplified frequent application cast. In the test, to introduce the election principle and means of press confectioning art and miscellaneous rapport part, otherwise also introducing calculation means on the work blank from of many kinds of product unfold dimension and simplified cast, and the means of looking up on the reference books of designing press die. Keywords: The craft; the technology capability; press process。 the size. 目 錄 I 目 錄 摘 要 ...........................................................................................................................................
