氣瓶沖壓成形工藝及模具設(shè)計摘 要：本設(shè)計題目為汽 瓶 拉深模，體現(xiàn)了典型拉深模的設(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(qiáng)了設(shè)計者對拉深模設(shè)計基礎(chǔ)知識的理解和運(yùn)用，為設(shè)計更復(fù)雜的拉深模具做好了鋪墊。本設(shè)計運(yùn)用拉深工藝及模具設(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；然后計算了拉深件的拉深力，便于選取壓力機(jī)噸位及確定壓力機(jī)型號；最后分析了拉深件的特征，便于確定模具的設(shè)計參數(shù)、設(shè)計要點(diǎn)及卸件裝置。本設(shè)計采用了多次拉深復(fù)合模成形汽 瓶 。成形原理可劃分為兩個階段：首先拉深凸模與凹模共同作用拉深成形外型，而后利用縮口模具對瓶口進(jìn)行縮口成形。關(guān)鍵詞：沖壓成形，落料拉深復(fù)合模，縮口模 cutting Operations and mold design for gas cylinderAbstract：The topic for the design is gas cylinder drawing design,It has manifested the typical drawinging 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 drawing die design basical knowledge,has prepareed for designing more complex drawing die.The design has utilize drawing 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 drawing 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 Multiple drawing compound die to form the products.The forming principle can be divided to two stages: First, drawing punch and die affect together to make the product formed，then use the necking die to make the ring of bottle formed.Key word: cutting Operations, Multiple drawing compound die， Reducing die
