【摘要】：精鍛機(jī)又稱“徑鍛機(jī)”,是世界上最先進(jìn)的鍛造設(shè)備之一。精鍛機(jī)具有脈沖鍛打和多向鍛打的特點,而且脈沖鍛打頻率高、速度快、每次變形量很小,省去了鍛造后的打磨等工序,可實現(xiàn)從坯料到成品的直接加工。精鍛機(jī)具有諸多優(yōu)點,如鍛件品質(zhì)高、生產(chǎn)率高、材料消耗低、工藝裝備少而簡單、通用性強(qiáng)、制造周期短、自動化程度高,勞動條件好等。因此精鍛機(jī)在軍工、航空航天、鐵路車軸、合金鋼鍛造及難鍛造的有色金屬等行業(yè)應(yīng)用廣泛。本文針對蘭石重工有限公司制造的1.6MN精鍛機(jī)進(jìn)行研究,以提升企業(yè)的裝備制造水平和市場競爭力,同時也填補(bǔ)我國精鍛機(jī)領(lǐng)域的空白。根據(jù)精鍛機(jī)的工作特點,本文重點研究了精鍛機(jī)主要參數(shù)的設(shè)計計算,結(jié)構(gòu)參數(shù)對主機(jī)運(yùn)動參數(shù)的影響因素等問題,探索精鍛機(jī)穩(wěn)定工作時的參數(shù)確定方法。對精鍛機(jī)的主要部件齒輪箱和鍛造箱進(jìn)行分析,得到合理的結(jié)構(gòu)設(shè)計參數(shù)。本文在充分論證精鍛機(jī)多種結(jié)構(gòu)型式后,根據(jù)企業(yè)的要求及各類精鍛機(jī)的特點,確定了1.6MN精鍛機(jī)采用無芯軸臥式的模式,主傳動采用機(jī)械傳動。其主傳動采用雙偏心結(jié)構(gòu)設(shè)計。對1.6MN精鍛機(jī)進(jìn)行以下了分析研究：1.對精鍛機(jī)的主要設(shè)計參數(shù)鍛造變形力、錘頭運(yùn)動參數(shù)、變形功進(jìn)行分析計算,為后續(xù)的精鍛機(jī)選型、設(shè)計提供理論依據(jù)。2.對1.6MN精鍛機(jī)主機(jī)錘頭位置控制及鍛造力反饋的計算,該計算為精鍛機(jī)控制部分的核心計算,同時鍛造力反饋推導(dǎo)計算為保護(hù)主機(jī)提供數(shù)據(jù)依據(jù)。3.根據(jù)1.6MN精鍛機(jī)主機(jī)齒輪箱中各齒輪的參數(shù)及驅(qū)動電機(jī)參數(shù),并對齒輪箱中關(guān)鍵零件——齒輪進(jìn)行齒面接觸強(qiáng)度和齒輪的彎曲強(qiáng)度計算,結(jié)果證明該設(shè)計能夠滿足設(shè)備的工作要求。5.使用有限元分析軟件Ansys Workbench對精鍛機(jī)關(guān)鍵受力件——鍛造箱體進(jìn)行有限元強(qiáng)度分析、模態(tài)分析、動力學(xué)分析及疲勞壽命分析,仿真結(jié)果顯示,鍛造箱在結(jié)構(gòu)強(qiáng)度和剛度、動載荷作用和疲勞壽命上均滿足要求,模態(tài)分析也表明外載荷不會激發(fā)結(jié)構(gòu)引起共振。因此,鍛造箱結(jié)構(gòu)在設(shè)計載荷作用下滿足強(qiáng)度條件、剛度條件和永久設(shè)計等。設(shè)備的研制成功表明,該1.6MN精鍛機(jī)具有可靠性、先進(jìn)性等優(yōu)點。1.6MN精鍛機(jī)研制成功后,將大大的為國內(nèi)企業(yè)節(jié)省大量外匯,并為后續(xù)開發(fā)系列化精鍛機(jī)打下堅實的基礎(chǔ)。
