1,要(yao)(yao)兼(jian)顧鑄鐵(tie)平(ping)板鑄件的(de)(de)度要(yao)(yao)求和成本(ben)各種鑄造方(fang)法所(suo)獲得(de)的(de)(de)鑄件度不(bu)同,初投資和生(sheng)產率也不(bu)一(yi)致,終(zhong)的(de)(de)經(jing)濟效(xiao)益也有差(cha)異(yi)。因此,要(yao)(yao)做到多、快(kuai)、好、省, 應當(dang)兼(jian)顧到各個(ge)方(fang)面。應對所(suo)選用(yong)的(de)(de)鑄造方(fang)法進行初步的(de)(de)成本(ben)估(gu)算,以確定(ding)經(jing)濟效(xiao)益高又能保(bao)證(zheng)鑄件要(yao)(yao)求的(de)(de)鑄造方(fang)法。
2,鑄鐵平板鑄造(zao)(zao)(zao)(zao)方(fang)(fang)(fang)法(fa)(fa)應(ying)(ying)和生(sheng)(sheng)(sheng)產(chan)(chan)(chan)批(pi)(pi)量(liang)相適(shi)應(ying)(ying),例如砂型(xing)(xing)鑄造(zao)(zao)(zao)(zao),大(da)量(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)工(gong)(gong)廠應(ying)(ying)創造(zao)(zao)(zao)(zao)條件(jian)采用技術的(de)造(zao)(zao)(zao)(zao)型(xing)(xing)、造(zao)(zao)(zao)(zao)芯方(fang)(fang)(fang)法(fa)(fa)。老式(shi)的(de)震擊式(shi)或震壓式(shi)造(zao)(zao)(zao)(zao)型(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)線(xian)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)率(lv)不夠(gou)高(gao),工(gong)(gong)人勞(lao)動強(qiang)度(du)大(da),噪聲大(da),不適(shi)應(ying)(ying)大(da)量(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)要(yao)求(qiu)(qiu),應(ying)(ying)逐步(bu)加以改造(zao)(zao)(zao)(zao)。對于小型(xing)(xing)鑄件(jian),可(ke)(ke)以采用水(shui)平分(fen)型(xing)(xing)或垂直分(fen)型(xing)(xing)的(de)無箱(xiang)(xiang)高(gao)壓造(zao)(zao)(zao)(zao)型(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)線(xian)、實型(xing)(xing)造(zao)(zao)(zao)(zao)型(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)效率(lv)又高(gao),占(zhan)地面積也(ye)少;對于鑄件(jian)可(ke)(ke)選用各種有(you)箱(xiang)(xiang)高(gao)壓造(zao)(zao)(zao)(zao)型(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)線(xian)、氣沖造(zao)(zao)(zao)(zao)型(xing)(xing)線(xian),以適(shi)應(ying)(ying)快(kuai)速、高(gao)度(du)造(zao)(zao)(zao)(zao)型(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)線(xian)的(de)要(yao)求(qiu)(qiu),造(zao)(zao)(zao)(zao)芯方(fang)(fang)(fang)法(fa)(fa)可(ke)(ke)選用:冷芯盒、熱(re)芯盒、殼芯等(deng)制芯方(fang)(fang)(fang)法(fa)(fa)。中等(deng)批(pi)(pi)量(liang)的(de)大(da)型(xing)(xing)鑄件(jian)可(ke)(ke)以考慮應(ying)(ying)用樹脂自硬砂造(zao)(zao)(zao)(zao)型(xing)(xing)和造(zao)(zao)(zao)(zao)芯。單件(jian)小批(pi)(pi)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)重型(xing)(xing)鑄件(jian),手工(gong)(gong)造(zao)(zao)(zao)(zao)型(xing)(xing)仍是重要(yao)的(de)方(fang)(fang)(fang)法(fa)(fa),手工(gong)(gong)造(zao)(zao)(zao)(zao)型(xing)(xing)能(neng)適(shi)應(ying)(ying)各種復雜的(de)要(yao)求(qiu)(qiu)比較靈(ling)活,不要(yao)求(qiu)(qiu)很多工(gong)(gong)藝裝(zhuang)備。批(pi)(pi)量(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)或長期生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)定型(xing)(xing)產(chan)(chan)(chan)品采用多箱(xiang)(xiang)造(zao)(zao)(zao)(zao)型(xing)(xing)、劈箱(xiang)(xiang)造(zao)(zao)(zao)(zao)型(xing)(xing)法(fa)(fa)比較適(shi)宜(yi),雖然(ran)模具(ju)、砂箱(xiang)(xiang)等(deng)開始(shi)投資高(gao),但可(ke)(ke)從(cong)節約造(zao)(zao)(zao)(zao)型(xing)(xing)工(gong)(gong)時(shi)、提高(gao)產(chan)(chan)(chan)品質量(liang)方(fang)(fang)(fang)面得(de)到補償(chang)。低壓鑄造(zao)(zao)(zao)(zao)、壓鑄、離心鑄造(zao)(zao)(zao)(zao)等(deng)鑄造(zao)(zao)(zao)(zao)方(fang)(fang)(fang)法(fa)(fa),因(yin)設備和模具(ju)的(de)價格昂貴,所(suo)以只(zhi)適(shi)合批(pi)(pi)量(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)。
3,鑄鐵平(ping)板(ban)造型(xing)方法(fa)應(ying)適(shi)合(he)工廠條(tiao)件(jian),例(li)如同(tong)樣(yang)是生產(chan)大型(xing)機床(chuang)(chuang)床(chuang)(chuang)身等鑄件(jian),一(yi)般采用(yong)組芯造型(xing)法(fa),不(bu)制作模樣(yang)和砂(sha)箱(xiang),在地(di)坑中組芯;而另(ling)外的(de)工廠則(ze)采用(yong)砂(sha)箱(xiang)造型(xing)法(fa),制作模樣(yang)。不(bu)同(tong)的(de)企(qi)業(ye)生產(chan)條(tiao)件(jian)(包括設備、場地(di)、員工素質等)、生產(chan)習慣、所積累(lei)的(de)經驗各不(bu)一(yi)樣(yang),應(ying)該根(gen)據這些(xie)條(tiao)件(jian)考慮(lv)適(shi)合(he)做什么產(chan)品和不(bu)適(shi)合(he)(或不(bu)能)做什么產(chan)品。
4,優(you)先采(cai)用(yong)砂型鑄(zhu)(zhu)造據(ju)統計在全部鑄(zhu)(zhu)鐵平板鑄(zhu)(zhu)件(jian)產量中,60~70的(de)鑄(zhu)(zhu)件(jian)是(shi)用(yong)砂型生(sheng)產的(de),而且其中70左右是(shi)用(yong)粘土(tu)砂型生(sheng)產的(de)。主(zhu)要原因(yin)是(shi)砂型鑄(zhu)(zhu)造較之其它鑄(zhu)(zhu)造方法成本(ben)低(di)、生(sheng)產工藝簡單、生(sheng)產周期短。
一般來(lai)講(jiang),對于中、大(da)型鑄(zhu)(zhu)件(jian),鑄(zhu)(zhu)鐵件(jian)可以用樹脂自硬砂(sha)型、鑄(zhu)(zhu)鋼件(jian)可以用水玻璃砂(sha)型來(lai)生(sheng)產(chan),可以獲得尺寸、表面(mian)光潔的(de)(de)(de)鑄(zhu)(zhu)件(jian),但成(cheng)本較高。當然,砂(sha)型鑄(zhu)(zhu)造(zao)生(sheng)產(chan)的(de)(de)(de)鑄(zhu)(zhu)件(jian)度、表面(mian)光潔度、材質的(de)(de)(de)密(mi)度和(he)金相組織、機械性能等方面(mian)往(wang)往(wang)較差,所(suo)以當鑄(zhu)(zhu)件(jian)的(de)(de)(de)這些性能要求 高時,應該采用其它鑄(zhu)(zhu)造(zao)方法,例如熔模(失臘)鑄(zhu)(zhu)造(zao)、壓(ya)鑄(zhu)(zhu)、低壓(ya)鑄(zhu)(zhu)造(zao)等等。
泊鑄(zhu)(zhu)機械量具廠鑄(zhu)(zhu)鐵平(ping)(ping)板(ban)完全按照 標準確GB7947-1999《鑄(zhu)(zhu)鐵平(ping)(ping)板(ban)》級別分為0、1、2、3, 刨(bao)5個級別。其中(zhong)2級以上為檢(jian)驗平(ping)(ping)板(ban),3級為劃線(xian)平(ping)(ping)板(ban)或基礎(chu)平(ping)(ping)板(ban)。
鑄(zhu)鐵(tie)平板(ban)(ban)結構:筋板(ban)(ban)式(shi)(shi)和單圍(wei)箱型(xing),雙圍(wei)箱型(xing)。為保證(zheng)度(du)穩定和滿(man)足(zu)載重等要(yao)(yao)求,臺(tai)面(mian)下方為立(li)式(shi)(shi)筋板(ban)(ban)結構。對于需要(yao)(yao)承載較大(da)重量的鑄(zhu)鐵(tie)平板(ban)(ban),應(ying)采(cai)用立(li)式(shi)(shi)工字 筋板(ban)(ban)。我公司鑄(zhu)鐵(tie)平板(ban)(ban)擁(yong)有(you)多(duo)樣(yang)式(shi)(shi),多(duo)型(xing)號規格(ge),多(duo)用途,工藝,做工細(xi),價格(ge)實,訂購熱線(xian):0317-8380005 13643379658!
