u形蓋落料模具設(shè)計(jì)論文(存儲(chǔ)版)
【正文】 板等組成。值此成文之際，特向老師致以忠心的感謝和誠摯的敬意。機(jī)械工業(yè)出版社，2000《模具設(shè)計(jì)基礎(chǔ)》北京 機(jī)械工業(yè)出版社，1998。高等教育出版社，2006《公差配合與測量技術(shù)》北京致謝 本次設(shè)計(jì)是在指導(dǎo)老師***老師的悉心指導(dǎo)下完成的。5安裝導(dǎo)料銷，承料板。但應(yīng)注意以下幾點(diǎn):(1).為便于加工和裝夾,一般都將毛坯鍛造成平行六面體。 (7).加工型孔部分:當(dāng)凹模較大時(shí),為減少線切割加工量,需將型孔漏料部分銑(車)出,只切割刃口高度。⑶.導(dǎo)向方式的選擇為了提高模具壽命和工件質(zhì)量，該模采用四導(dǎo)柱的導(dǎo)向方式。通常說的沖裁力是指沖裁力的最大值，它是選用壓力機(jī)和設(shè)計(jì)模具的重要依據(jù)之一。若考慮到料頭、料尾和邊余料的材料消耗，則一張板料(或帶料、條料)上總的具體計(jì)算如下： =*100%=*100%=%選1220mm1800mm的鋼板，每張鋼板可裁剪=，每張條料有=，則： =100℅ =1707800 2074000%。沖件與沖件之間或沖件與條料側(cè)邊之間均無搭邊，沿直線或曲線切斷條料而獲得沖件。通過對(duì)上述三種方案的分析比較，該件的沖壓生產(chǎn)采用方案三為佳。采用單工序模生產(chǎn)。17 沖壓設(shè)備選定6 材料利用率的計(jì)算5 第二章 排樣設(shè)計(jì)及工藝參數(shù)的計(jì)算1 第一章 沖壓件及其工藝分析 本次的畢業(yè)設(shè)計(jì)課題來源于工廠的工作實(shí)踐, 模具結(jié)構(gòu)也較為常見，對(duì)于我們初學(xué)者是一種鍛煉。 畢業(yè)設(shè)計(jì)用紙中文摘要目前，我國經(jīng)濟(jì)仍處于高速發(fā)展階段，國際上經(jīng)濟(jì)全球化發(fā)展趨勢日趨明顯，這為我國模具工業(yè)高速發(fā)展提供了良好的條件和機(jī)遇。級(jí)進(jìn)模設(shè)計(jì)的要點(diǎn)之一就是毛坯排樣，排樣方案對(duì)材料的利用率、沖壓加工的工藝性以及模具的結(jié)構(gòu)和壽命等有著顯著的影響。s mold industry to provide good conditions and opportunities. For stamping, the singlestation single die structure, low productivity, and sheet metal parts can not be too plicated, or need more singlestation dies vice can be achieved. If the use of progressive die stamping production, you can change these shortings. Multiposition progressive die progressive die in general developed on the basis of a high precision, high efficiency, long life of the mold, the mold is an important representative of technologyintensive, is one of the development die. The punching die blanking addition to the work, but also the characteristics of part structure based on the nature and shape, plete beading, punching hole, bending, deep drawing forming process can even be pleted in the mold assembly process. Stamping, it will be with the material or strip materials sent from the mold after the entrance, step in the strictly controlled conditions, accuracy, forming process in accordance with the order arranged by the continuous pressing of the station, at the last station, or by punching
