1,要兼顧鑄(zhu)(zhu)鐵(tie)平板(ban)鑄(zhu)(zhu)件的(de)(de)度要求(qiu)和(he)成本各種鑄(zhu)(zhu)造方法所(suo)(suo)獲(huo)得的(de)(de)鑄(zhu)(zhu)件度不同,初(chu)投資(zi)和(he)生(sheng)產率也(ye)不一致(zhi),終的(de)(de)經(jing)濟效益也(ye)有(you)差異。因此,要做到(dao)多、快、好、省, 應當兼顧到(dao)各個方面。應對所(suo)(suo)選用(yong)的(de)(de)鑄(zhu)(zhu)造方法進行(xing)初(chu)步的(de)(de)成本估算,以確定(ding)經(jing)濟效益高又能保證(zheng)鑄(zhu)(zhu)件要求(qiu)的(de)(de)鑄(zhu)(zhu)造方法。
2,鑄(zhu)鐵平板鑄(zhu)造(zao)(zao)(zao)(zao)方(fang)法(fa)(fa)(fa)應和生(sheng)(sheng)(sheng)(sheng)產(chan)批(pi)(pi)量相適應,例如砂型(xing)鑄(zhu)造(zao)(zao)(zao)(zao),大量生(sheng)(sheng)(sheng)(sheng)產(chan)的(de)(de)(de)(de)(de)工(gong)廠應創造(zao)(zao)(zao)(zao)條(tiao)件(jian)(jian)采用(yong)技(ji)術(shu)的(de)(de)(de)(de)(de)造(zao)(zao)(zao)(zao)型(xing)、造(zao)(zao)(zao)(zao)芯(xin)(xin)方(fang)法(fa)(fa)(fa)。老式(shi)(shi)的(de)(de)(de)(de)(de)震(zhen)擊式(shi)(shi)或震(zhen)壓(ya)式(shi)(shi)造(zao)(zao)(zao)(zao)型(xing)機生(sheng)(sheng)(sheng)(sheng)產(chan)線(xian)(xian)(xian)生(sheng)(sheng)(sheng)(sheng)產(chan)率不夠高(gao)(gao),工(gong)人勞動強度(du)大,噪聲大,不適應大量生(sheng)(sheng)(sheng)(sheng)產(chan)的(de)(de)(de)(de)(de)要求(qiu),應逐步加(jia)以(yi)改造(zao)(zao)(zao)(zao)。對于(yu)小(xiao)型(xing)鑄(zhu)件(jian)(jian),可(ke)(ke)以(yi)采用(yong)水平分型(xing)或垂直分型(xing)的(de)(de)(de)(de)(de)無(wu)箱高(gao)(gao)壓(ya)造(zao)(zao)(zao)(zao)型(xing)機生(sheng)(sheng)(sheng)(sheng)產(chan)線(xian)(xian)(xian)、實型(xing)造(zao)(zao)(zao)(zao)型(xing)生(sheng)(sheng)(sheng)(sheng)產(chan)效率又高(gao)(gao),占地(di)面積也少;對于(yu)鑄(zhu)件(jian)(jian)可(ke)(ke)選用(yong)各種(zhong)(zhong)有箱高(gao)(gao)壓(ya)造(zao)(zao)(zao)(zao)型(xing)機生(sheng)(sheng)(sheng)(sheng)產(chan)線(xian)(xian)(xian)、氣沖造(zao)(zao)(zao)(zao)型(xing)線(xian)(xian)(xian),以(yi)適應快速、高(gao)(gao)度(du)造(zao)(zao)(zao)(zao)型(xing)生(sheng)(sheng)(sheng)(sheng)產(chan)線(xian)(xian)(xian)的(de)(de)(de)(de)(de)要求(qiu),造(zao)(zao)(zao)(zao)芯(xin)(xin)方(fang)法(fa)(fa)(fa)可(ke)(ke)選用(yong):冷芯(xin)(xin)盒(he)、熱(re)芯(xin)(xin)盒(he)、殼芯(xin)(xin)等(deng)(deng)制芯(xin)(xin)方(fang)法(fa)(fa)(fa)。中等(deng)(deng)批(pi)(pi)量的(de)(de)(de)(de)(de)大型(xing)鑄(zhu)件(jian)(jian)可(ke)(ke)以(yi)考(kao)慮應用(yong)樹脂自硬砂造(zao)(zao)(zao)(zao)型(xing)和造(zao)(zao)(zao)(zao)芯(xin)(xin)。單件(jian)(jian)小(xiao)批(pi)(pi)生(sheng)(sheng)(sheng)(sheng)產(chan)的(de)(de)(de)(de)(de)重型(xing)鑄(zhu)件(jian)(jian),手工(gong)造(zao)(zao)(zao)(zao)型(xing)仍(reng)是重要的(de)(de)(de)(de)(de)方(fang)法(fa)(fa)(fa),手工(gong)造(zao)(zao)(zao)(zao)型(xing)能適應各種(zhong)(zhong)復(fu)雜的(de)(de)(de)(de)(de)要求(qiu)比較(jiao)靈活,不要求(qiu)很(hen)多(duo)(duo)工(gong)藝裝備(bei)(bei)。批(pi)(pi)量生(sheng)(sheng)(sheng)(sheng)產(chan)或長期生(sheng)(sheng)(sheng)(sheng)產(chan)的(de)(de)(de)(de)(de)定型(xing)產(chan)品采用(yong)多(duo)(duo)箱造(zao)(zao)(zao)(zao)型(xing)、劈箱造(zao)(zao)(zao)(zao)型(xing)法(fa)(fa)(fa)比較(jiao)適宜,雖然模具、砂箱等(deng)(deng)開始投(tou)資(zi)高(gao)(gao),但可(ke)(ke)從節約造(zao)(zao)(zao)(zao)型(xing)工(gong)時、提高(gao)(gao)產(chan)品質量方(fang)面得(de)到補償。低壓(ya)鑄(zhu)造(zao)(zao)(zao)(zao)、壓(ya)鑄(zhu)、離心鑄(zhu)造(zao)(zao)(zao)(zao)等(deng)(deng)鑄(zhu)造(zao)(zao)(zao)(zao)方(fang)法(fa)(fa)(fa),因設備(bei)(bei)和模具的(de)(de)(de)(de)(de)價格昂(ang)貴,所以(yi)只適合批(pi)(pi)量生(sheng)(sheng)(sheng)(sheng)產(chan)。
3,鑄(zhu)鐵平板造型方法應(ying)適合工廠條(tiao)件,例如同(tong)樣是生產(chan)(chan)大型機床床身(shen)等(deng)鑄(zhu)件,一般采(cai)用組芯造型法,不制(zhi)(zhi)作(zuo)模(mo)樣和砂箱,在地坑中組芯;而另外(wai)的工廠則采(cai)用砂箱造型法,制(zhi)(zhi)作(zuo)模(mo)樣。不同(tong)的企業(ye)生產(chan)(chan)條(tiao)件(包括設備、場地、員(yuan)工素質等(deng))、生產(chan)(chan)習慣、所積累的經驗各(ge)不一樣,應(ying)該根據這些條(tiao)件考慮適合做什么產(chan)(chan)品(pin)和不適合(或不能)做什么產(chan)(chan)品(pin)。
4,優(you)先采用(yong)砂(sha)型(xing)(xing)鑄造據統計在全部(bu)鑄鐵平板(ban)鑄件產(chan)量中,60~70的(de)鑄件是用(yong)砂(sha)型(xing)(xing)生產(chan)的(de),而且其中70左右是用(yong)粘土(tu)砂(sha)型(xing)(xing)生產(chan)的(de)。主要(yao)原(yuan)因是砂(sha)型(xing)(xing)鑄造較(jiao)之其它(ta)鑄造方法成本低、生產(chan)工(gong)藝簡單、生產(chan)周期(qi)短(duan)。
一(yi)般(ban)來(lai)講(jiang),對于(yu)中、大(da)型鑄(zhu)件(jian)(jian),鑄(zhu)鐵件(jian)(jian)可(ke)以(yi)用(yong)樹脂自(zi)硬(ying)砂型、鑄(zhu)鋼件(jian)(jian)可(ke)以(yi)用(yong)水玻璃砂型來(lai)生(sheng)產(chan),可(ke)以(yi)獲得尺寸、表面光潔的鑄(zhu)件(jian)(jian),但成本(ben)較(jiao)高(gao)(gao)。當(dang)然,砂型鑄(zhu)造(zao)生(sheng)產(chan)的鑄(zhu)件(jian)(jian)度、表面光潔度、材質的密度和(he)金相(xiang)組織、機械性(xing)(xing)能(neng)等方面往往較(jiao)差,所以(yi)當(dang)鑄(zhu)件(jian)(jian)的這(zhe)些性(xing)(xing)能(neng)要求(qiu) 高(gao)(gao)時(shi),應該采用(yong)其它(ta)鑄(zhu)造(zao)方法,例如熔模(失(shi)臘)鑄(zhu)造(zao)、壓(ya)鑄(zhu)、低壓(ya)鑄(zhu)造(zao)等等。
泊(bo)鑄(zhu)(zhu)機械(xie)量(liang)具廠鑄(zhu)(zhu)鐵(tie)平(ping)板完全按照 標準(zhun)確GB7947-1999《鑄(zhu)(zhu)鐵(tie)平(ping)板》級別分為0、1、2、3, 刨5個級別。其中2級以(yi)上(shang)為檢驗平(ping)板,3級為劃線平(ping)板或基礎平(ping)板。
鑄(zhu)(zhu)鐵(tie)平板(ban)結構:筋(jin)板(ban)式和單圍(wei)箱型,雙圍(wei)箱型。為保證度穩定(ding)和滿足載重(zhong)等要(yao)求(qiu),臺面下方為立式筋(jin)板(ban)結構。對(dui)于需要(yao)承載較(jiao)大重(zhong)量的鑄(zhu)(zhu)鐵(tie)平板(ban),應采用(yong)立式工字 筋(jin)板(ban)。我公司鑄(zhu)(zhu)鐵(tie)平板(ban)擁有(you)多(duo)(duo)樣式,多(duo)(duo)型號規格(ge),多(duo)(duo)用(yong)途,工藝,做工細(xi),價格(ge)實,訂購熱線:0317-8380005 13643379658!
