style="text-indent:25px">1842年，英國工程師內史密斯創(chuàng)制一臺蒸汽錘，開始了蒸汽動力鍛造機械的時代。1795年,英國的布拉默發(fā)明水壓機，但直到19世紀中葉，濟南鍛錘，由于大鍛件的需要才應用于鍛造。隨著電動機的發(fā)明，十九世紀末出現了以電為動力的機械壓力機和空氣錘，并獲得迅速發(fā)展。第二次世界大戰(zhàn)以來，七十五萬千牛的模鍛水壓機、一千五百千焦的對擊錘，濟南鍛錘，濟南鍛錘、六萬千牛的板料沖壓壓力機、十六萬千牛的熱模鍛壓力機等重型鍛壓機械，和一些自動冷鐓機相繼問世，形成了門類齊全的鍛造機械體系。鍛壓設備機械加工余量小，材料利用率高。濟南鍛錘</p><div

style="text-indent:25px">鍛造設備的發(fā)展：1、我國雖是世界上發(fā)明使用鑄造技術較早的國家之一，但現代化的鑄造生產，起步晚技術水平低，國內鑄造設備的起步則更晚。能在短時間內獲得長足的發(fā)展，尤其能在自主創(chuàng)新方面取得如此優(yōu)異的成績，確屬不易。2、國內的鑄造設備企業(yè)，面對擁有數十年、甚至更長發(fā)展時間的西方強勁對手，不畏艱難、頑強拼搏、求實創(chuàng)新、銳意進取，從一窮二白到接軌世界再到現在的智能化帶領、高質量發(fā)展，獨具匠心的產品不僅展示了中國鑄造轉型升級、創(chuàng)新發(fā)展的較新成果，更彰顯出中國鑄造由大向強的實力與底氣。濟南立式擺碾機液壓螺旋壓力機的噸位已經超過8000t，模鍛液壓機超過70000t。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="濟南鍛錘,鍛造設備" src="https://tyunfile.71360.com/UploadFile/15961751058/637340624132998047/4400811.png"></div><p style="text-indent:25px">鍛造設備的發(fā)展：鍛造機械改變是從19世紀開始的，向重型和大型方向發(fā)展的趨勢，轉而向高速、高效、自動、精密、**、多品種生產等方向發(fā)展。于是出現了每分種行程2000次的高速壓力機、六萬千牛的三坐標多工位壓力機、兩萬五千千牛的精密沖裁壓力機、能冷鐓直徑為48毫米鋼材的多工位自動冷鐓機和多種自動機，自動生產線等。各種機械控制的、數字控制的和計算機控制的自動鍛造機械以及與之配套的DYH系列鍛造操作機、機械手和工業(yè)機器人也相繼研制成功?，F代化的鍛壓機械可生產精確制品，有良好的勞動條件，環(huán)境污染很小。</p><p style="text-indent:25px">鍛造設備的選擇原則：模鍛錘上模鍛是較早發(fā)展的模鍛方法。盡管各種新型模鍛設備和模鍛工藝方法不斷出現，但由于鍛錘上模鍛具有靈活、適應性強、金屬易于充滿模膛、可以單模膛和多模膛模鍛以及設備價格低廉等優(yōu)點，因此，它在模鍛件生產中仍占重要地位。然而，鍛錘上模鍛也有其難以克服的缺點，例如噪聲和振動大、污染環(huán)境、勞動條件差，因為速度高，不適于鍛造低塑性的特種合金。模鍛錘（含對擊錘）開始打擊鍛件的速度在4m/s～8m/s，屬于沖擊性載荷，錘頭打擊速度高而且變化大，不適于鍛造低塑性和再結晶速度慢的特種合金，塑性不是太差的特種合金，也可以在模鍛錘和對擊錘上進行鍛造，不過加熱溫度與壓力機模鍛不同。此外，鍛造開始時要輕打，隨后逐漸加重錘擊力度，并嚴格控制每錘的變形量。終鍛工序較后一錘的變形量尤其重要，以免產生不均勻的晶粒組織。模鍛錘（含對擊錘）開始打擊鍛件的速度在4m/s～8m/s，屬于沖擊性載荷。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="濟南鍛錘,鍛造設備" src="https://tyunfile.71360.com/UploadFile/15961751058/637340623978291015/5884873.png"></div><p style="text-indent:25px">鍛造設備的技術發(fā)展情況：傳統(tǒng)的立式冷擺輾成形機，擺頭可以實現圓、直線、螺旋線和多葉玫瑰線4種運動軌跡，其中直線、螺旋線和多葉玫瑰線3種軌跡擺頭均通過中心點，該點擺頭軸線與設備垂直軸線重合，擺角為0°，模具與工件坯料完全接觸，瞬間成形力陡增。圓形軌跡擺頭不通過中心點，擺輾過程為連續(xù)的局部成形，這也是目前極少采用螺旋線和多葉玫瑰線軌跡成形，而90%以上的擺輾件成形均采用圓形軌跡的原因。針對直線、螺旋線和多葉玫瑰線3種軌跡擺頭均通過中心點而使成形力陡增這一問題，北京機電研究所開發(fā)出了擺頭不通過中心點的橢圓、螺旋線和多葉玫瑰線運動軌跡，這樣即能夠解決擺頭通過中心點而使成形力陡增的問題，使擺輾過程均為連續(xù)的局部成形，對設計新型擺輾機、改進擺頭結構、完善擺輾成形工藝具有重要的技術意義?？梢愿鶕酒髽I(yè)現有設備狀況和鍛件批量較經濟地選擇。濟南驅動輪生產線</p><p style="text-indent:25px">螺旋壓力機的實際打擊載荷可以達到其名義載荷的1.6倍～2.0倍，特別適于薄壁鍛件的精鍛。濟南鍛錘</p><p style="text-indent:25px">鈦合金自由鍛造設備的選擇：自由鍛造在鈦合金生產中是非常重要的、必不可少的加工工序。一般來說，鍛鋼的鍛造設備可以鍛鈦，但鈦合金的變形抗力大，而且鈦合金的變形抗力隨溫度降低急劇變大，因此，在變形程度相同的情況下，鍛造鈦合金比鍛造低合金鋼需要更大噸位的設備，單位時間內鍛打次數更高些。目前，鈦合金自由鍛造設備主要有兩大類：鍛錘和液壓機。在鍛造過程中，一般根據鈦合金坯料的大小，不同牌號鈦合金的金屬性能，鍛造的成品尺寸、形狀等因素，選擇不同的鍛造設備。下面通過鍛錘和液壓機來介紹鈦合金自由鍛造設備的選擇。濟南鍛錘</p></p><br
