I 折彎墊片沖壓成形工藝與模具設(shè)計 摘要 本設(shè)計題目為墊 片 沖裁模 體現(xiàn)了典型沖裁模的設(shè)計要求 內(nèi)容及方向 有一定的設(shè)計意義 通過對該模具的設(shè)計 加強了設(shè)計者對沖裁模設(shè)計基礎(chǔ)知 識的理解和運用 為設(shè)計更復(fù)雜的沖裁模具做好了鋪墊 本設(shè)計運用沖裁工藝及模具設(shè)計的基礎(chǔ)知識 首先分析了板材的性能要求 為選取模具的類型做好了準(zhǔn)備 然后計算了沖裁件的沖裁力 便于選取壓力機 噸位及確定壓力機型號 最后分析了沖裁件的特征 便于確定模具的設(shè)計參數(shù) 設(shè)計要點及卸件裝置 本設(shè)計采用了沖孔 落料復(fù)合模成形墊 片 成形原理可劃分為三個階段 首先沖孔凸模與凹模共同作用先沖出四個 5mm 而后利用第一步?jīng)_出的四個 5mm 孔做精確定位使外形凸模與凹模共同作用使工件落料成形 最后一步是 進(jìn)行折彎 關(guān)鍵詞 沖孔 落料復(fù)合模 沖孔凸模 凹模 壓力機噸位 II Bending sheet stamping forming technology and die design Abstract The topic for the design is pad blanking die design It has manifested the typical blanking die s design request the content and the direction has certain design significance Through the design of the component mold strengthens the designer s understand and utilize to the blanking die design basical knowledge has prepareed for designing more complex blanking die The design has utilize blanking craft and the basical knowledge of the mold design has first analyzed the property requirement of the plate has prepared for selecting the mold type then has calculated the blanking strength has advantaged to select the press tonnage and determine press model Finally has analyzed the characteristic of the products has advantaged to finite the mold design variable the design main point and shedder This design used piercing and blanking progressive die to form the products The forming principle can be divided to two stages First piercing punch and die affect together and pierce four holes of 3 2mm and one hole of 8 5mm then use the four holes and the one hole as pinpoint to make the product formed Key word Piercing and blanking progressive die Piercing punch Press Tonnage
