什麼是自由鍛造加工?

自由鍛造加工（簡稱自在鍛）shijinshusuxingjiagongdeyizhongjianlveerlingmindegenbenchengxingbanfa。tashishiyongduanyashebeishangxiazhenkuaiheyixiejianlvetongyongdongxi，shipiliaozaiyalixiaoguoxiafashengsuxingbianxing。自由鍛造有(you)手(shou)藝(yi)鑄(zhu)造(zao)和(he)機(ji)器(qi)鑄(zhu)造(zao)之(zhi)分(fen)。跟(gen)著(zhe)機(ji)器(qi)製(zhi)造(zao)工(gong)業(ye)的(de)迅(xun)速(su)發(fa)展(zhan)，如(ru)今(jin)出(chu)產(chan)中(zhong)首(shou)要(yao)選(xuan)用(yong)機(ji)器(qi)鑄(zhu)造(zao)。依(yi)據(ju)鑄(zhu)造(zao)設(she)備(bei)類(lei)型(xing)不(bu)同(tong)，機(ji)器(qi)鑄(zhu)造(zao)可(ke)分(fen)為(wei)鍛(duan)錘(chui)自(zi)在(zai)鍛(duan)和(he)水(shui)壓(ya)機(ji)自(zi)在(zai)鍛(duan)兩(liang)種(zhong)。前(qian)者(zhe)用(yong)以(yi)鑄(zhu)造(zao)中(zhong)小(xiao)鍛(duan)件(jian)，後(hou)者(zhe)首(shou)要(yao)鑄(zhu)造(zao)大(da)型(xing)鍛(duan)件(jian)。 

因為自由鍛造加工所suo用yong的de東dong西xi簡jian略lve，通tong用yong性xing強qiang
，靈ling敏min性xing大da，因yin而er合he適shi單dan件jian和he小xiao批pi量liang鍛duan件jian的de出chu產chan。鍛duan造zao加jia工gong鍛duan件jian是shi由you坯pi料liao逐zhu漸jian變bian形xing而er成cheng，東dong西xi隻zhi與yu坯pi料liao有you些xie觸chu摸mo，故gu所suo需xu設she備bei功gong率lv比bi模mo鍛duan要yao小xiao得de多duo，所suo以yi鍛duan造zao加jia工gong也ye適shi於yu鑄zhu造zao大da型xing鍛duan件jian。如ru萬wan噸dun模mo鍛duan水shui壓ya機ji隻zhi能neng模mo鍛duan幾ji百bai公gong斤jin重zhong的de鍛duan件jian，而er萬wan噸dun自zi在zai鍛duan水shui壓ya機ji卻que可ke鑄zhu造zao重zhong達da百bai噸dun以yi上shang大da型xing鍛duan件jian。可ke見jian，關guan於yu大da型xing鍛duan件jian的de鑄zhu造zao，隻zhi能neng采cai取qu鍛造加工造成形技術。
