車型頂蓋修邊模具設(shè)計畢業(yè)設(shè)計(存儲版)
【正文】 的整體形狀是一個盒子的形狀，中間為Z向的掏空，四周為了強度的要求采用了側(cè)面掏空的形式。側(cè)銷的布置：側(cè)銷分為兩種，一種是工作側(cè)銷，另外一種是安全側(cè)銷。彈簧要均勻布置，保證沒有偏心布置。彈簧常數(shù)95/mm *40= 氮氣彈簧壓料芯中間導(dǎo)柱導(dǎo)向設(shè)計。 壓料行程為余量a加上板件料厚，再加上切口切入量的總和。 鑲塊鑲塊螺釘設(shè)計要求：螺釘孔中心離擋墻面及配合面距離C1～C2，D1～D2為5mm的整數(shù)倍；螺釘孔中心間距A1～A5，B1～B5為20mm的整數(shù)倍；使用M16的螺釘；鑲塊在設(shè)計中要考慮以下三點：1， 項目總體要求，在不同的項目當中由于產(chǎn)品的生命周期不盡相同，導(dǎo)致鑲塊的結(jié)構(gòu)式樣不同；2， 鑲塊鑄造，加工的需求：鑲塊鑄造要求鑲塊設(shè)計要符合鑄造工藝性，加工要保證加工刀具可以加工到每個加工面；3， 一個整車項目，在整個周期中設(shè)變的次數(shù)是很頻繁的，修邊線常常改動，在設(shè)計過程中往往會留有余量 鑲塊基于以上三點考慮，我們利用的UG中的鑲塊制作工具來進行鑲塊設(shè)計，此種帶參鑲塊設(shè)計的方法可以克服以上三點中的所有問題。廢料滑板的角度應(yīng)≥25176。斜楔沖孔采用帶頂銷的臺肩凸模，當孔徑較?。讖叫∮?毫米）時，為了便于更換凸模，應(yīng)選用球鎖快換凸模。廢料刀原則上設(shè)計成直刃口，切刃高度應(yīng)與修邊刃口有一高度差， 廢料刀切刃長度應(yīng)略大于廢料對應(yīng)尺寸。 DL圖內(nèi)容由外向內(nèi)兩條線分別代表修邊線，整形線。覆蓋件的工藝設(shè)計、沖模結(jié)構(gòu)設(shè)計和沖模制造工藝都具有特殊性。 基于UG的覆蓋件模具設(shè)計 UG簡介本課題是基于UG的汽車頂蓋修邊模具設(shè)計。廠商認為只要增加質(zhì)檢次數(shù)就可以保證產(chǎn)品質(zhì)量。眾所周知，汽車沖壓件中頂蓋是最大的沖壓件，頂蓋質(zhì)量的好壞直接影響整車的外觀和質(zhì)量，同時還影響著前風擋玻璃、前后車門、前后門柱、后圍等幾個較大的沖壓件的裝配質(zhì)量，因此，頂蓋是一個在工藝設(shè)計、模具設(shè)計以及制造等方面都具有較大難度和較高要求的沖壓件。關(guān)鍵詞：汽車頂蓋 修邊模 修邊模具設(shè)計 UG A model based on UG that trimming mold design Abstract：In the industrial life, with all sorts of press and put pressure on board in the specialized tools, through the pressure to put metal and nonmetal material for pointing out the shape of the parts or products, the special tools collectively referred to as the mould. At present, the mould industry has bee the important basis of the industry of the national economy. The car industry is pillar industry of the national economy, the update mainly depends on the car body development cycles. And the development of key to body automobile covering die design and manufacture. Above that is the top of the car partment cover plate, the subject is using UG design that car trimming mold. The cover of the stamping process, mold design and manufacturing process, debugging and use and other than die, there is the unique. To stamping process is concerned, and that other stamping pared with thin materials, shape plex, and more for threedimensional surface, structure size and surface quality higher characteristic, to get a qualified covering, the key lies in its technology is reasonable. Use of 3 d software to develop parametric die structure, establishing standard parts library to mold for overall drive, can greatly decrease the repetitive work, improve the design efficiency, shorten the design cycle. From the analysis of the above that stamping technology, can see, material thickness of mm above that, belong to the plate material forming, need to pass and delay, trimming and plastic three
