自由鍛(duan)工(gong)藝過程的實質是利(li)用簡(jian)單的工(gong)具，逐步改變原(yuan)坯料的形狀、尺寸和組織結構，以獲(huo)得(de)所需鍛(duan)件(jian)的加工(gong)過程。自由鍛(duan)工(gong)藝所研究的內容(rong)是：鍛(duan)件(jian)的成形規律和提高鍛(duan)件(jian)質量的方法兩個方面。

自(zi)由鍛(duan)的(de)(de)優點是：所(suo)用工具(ju)簡單，通(tong)用性強(qiang)、靈活性大，因此(ci)適合單件和(he)小批鍛(duan)件，特別是特大型鍛(duan)件的(de)(de)生(sheng)產，這對于新產品(pin)的(de)(de)試制、非標準的(de)(de)工裝夾具(ju)和(he)模具(ju)的(de)(de)制造提(ti)供了經濟快(kuai)捷的(de)(de)方法。為了減(jian)輕模鍛(duan)設(she)備(bei)的(de)(de)負擔或充分利(li)用現有模鍛(duan)設(she)備(bei)，簡化模鍛(duan)結(jie)構，有些模鍛(duan)件的(de)(de)制坯工步(bu)也在自(zi)由鍛(duan)設(she)備(bei)上完成。

以下(xia)內(nei)容由(you)本公司為您提供，今天(tian)我(wo)們來分(fen)享鍛件鍛造廠家(jia)的內(nei)容，希望對大家(jia)有所(suo)幫助：

鍛件的預成形坯：

預(yu)成(cheng)形坯(pi)(pi)的(de)(de)設計是(shi)根據鍛件的(de)(de)重量(liang)、密(mi)度(du)、形狀(zhuang)和尺(chi)(chi)寸要求，設計預(yu)成(cheng)形坯(pi)(pi)的(de)(de)密(mi)度(du)、形狀(zhuang)和尺(chi)(chi)寸的(de)(de)。基本的(de)(de)原則就是(shi)在鍛造時(shi)有利(li)于(yu)預(yu)成(cheng)形坯(pi)(pi)的(de)(de)致密(mi)和充(chong)滿(man)(man)模(mo)(mo)膛(tang)，同(tong)時(shi)在充(chong)滿(man)(man)模(mo)(mo)膛(tang)前應(ying)盡可(ke)能使預(yu)成(cheng)形坯(pi)(pi)有較大的(de)(de)橫(heng)向塑(su)性(xing)(xing)流動。但在充(chong)滿(man)(man)模(mo)(mo)具型(xing)腔前的(de)(de)塑(su)性(xing)(xing)變形量(liang)不能大于(yu)預(yu)成(cheng)形坯(pi)(pi)塑(su)性(xing)(xing)允許(xu)的(de)(de)極限值。另外還必須考慮預(yu)成(cheng)形坯(pi)(pi)在充(chong)滿(man)(man)模(mo)(mo)具型(xing)腔時(shi)，各(ge)部位的(de)(de)應(ying)力(li)(li)狀(zhuang)態應(ying)盡可(ke)能處于(yu)三向壓(ya)應(ying)力(li)(li)狀(zhuang)態下，避免或減小拉(la)應(ying)力(li)(li)狀(zhuang)態。

密(mi)(mi)度(du)是預(yu)(yu)成(cheng)(cheng)(cheng)形(xing)(xing)坯(pi)(pi)的(de)(de)基本參數。根據預(yu)(yu)成(cheng)(cheng)(cheng)形(xing)(xing)坯(pi)(pi)密(mi)(mi)度(du)及(ji)鍛件質量，求得預(yu)(yu)成(cheng)(cheng)(cheng)形(xing)(xing)坯(pi)(pi)的(de)(de)體積，然后根據預(yu)(yu)成(cheng)(cheng)(cheng)形(xing)(xing)坯(pi)(pi)的(de)(de)高(gao)徑比，分別確定(ding)預(yu)(yu)成(cheng)(cheng)(cheng)形(xing)(xing)坯(pi)(pi)的(de)(de)高(gao)度(du)及(ji)徑向尺寸。以此(ci)作為壓制模(mo)尺寸設計的(de)(de)依據。粉(fen)末鍛件的(de)(de)密(mi)(mi)度(du)主(zhu)要(yao)(yao)是由鍛造(zao)變形(xing)(xing)決定(ding)的(de)(de)，一(yi)般(ban)(ban)與預(yu)(yu)成(cheng)(cheng)(cheng)形(xing)(xing)坯(pi)(pi)密(mi)(mi)度(du)關系不大(da)。預(yu)(yu)成(cheng)(cheng)(cheng)形(xing)(xing)坯(pi)(pi)密(mi)(mi)度(du)選(xuan)擇主(zhu)要(yao)(yao)考慮(lv)預(yu)(yu)成(cheng)(cheng)(cheng)形(xing)(xing)坯(pi)(pi)要(yao)(yao)有足夠強度(du)，保證在生產工序之(zhi)間的(de)(de)傳輸過程不損壞，形(xing)(xing)狀完整。為此(ci)一(yi)般(ban)(ban)冷壓制后的(de)(de)預(yu)(yu)成(cheng)(cheng)(cheng)形(xing)(xing)坯(pi)(pi)密(mi)(mi)度(du)為理論密(mi)(mi)度(du)的(de)(de)80%左右。
