實型離心鑄造雙盤法蘭直管及穿墻法蘭直管的設備及方法與流程

本發明涉(she)及(ji)(ji)離心(xin)鑄造技(ji)術領域中的一(yi)種(zhong)實型離心(xin)鑄造雙盤法蘭(lan)直管(guan)及(ji)(ji)穿墻(qiang)法蘭(lan)直管(guan)的設備及(ji)(ji)方法,特別(bie)涉(she)及(ji)(ji)雙盤法蘭(lan)及(ji)(ji)穿墻(qiang)法蘭(lan)直管(guan)離心(xin)一(yi)型多件(jian)鑄造。



背景技術:

目前,國內外市(shi)場上用于承壓的(de)輸水(shui)管(guan)線多數采用離心球墨(mo)鑄鐵管(guan)。由(you)于受雙(shuang)盤(pan)法蘭(lan)(lan)(lan)和穿(chuan)墻(qiang)法蘭(lan)(lan)(lan)在金屬模(mo)中脫模(mo)困難的(de)限(xian)制,供應市(shi)場的(de)雙(shuang)盤(pan)法蘭(lan)(lan)(lan)管(guan)及穿(chuan)墻(qiang)法蘭(lan)(lan)(lan)管(guan)有以下幾種生(sheng)產方式:

一(yi),焊(han)接(jie)(jie)雙(shuang)(shuang)盤法(fa)蘭管(guan)。焊(han)接(jie)(jie)雙(shuang)(shuang)盤法(fa)蘭管(guan)存在(zai)的(de)主要問題:(1)焊(han)縫(feng)與鑄(zhu)管(guan)本體材(cai)質(zhi)不一(yi)致,“異質(zhi)”焊(han)縫(feng)強(qiang)度低。(2)焊(han)接(jie)(jie)區(qu)域(yu)應力(li)集中,切(qie)無(wu)法(fa)完(wan)全消除。(3)管(guan)子兩端的(de)法(fa)蘭在(zai)焊(han)接(jie)(jie)前通(tong)過(guo)人(ren)工裝配(pei),尺寸誤差(cha)大(da);焊(han)接(jie)(jie)過(guo)程(cheng)中受(shou)熱應力(li)影響(xiang)很(hen)難保(bao)證兩法(fa)蘭孔的(de)同心度和盤面(mian)的(de)平行(xing)度。(4)目前國(guo)內外尚(shang)無(wu)鑄(zhu)鐵焊(han)縫(feng)的(de)評(ping)價標準,因(yin)此焊(han)接(jie)(jie)質(zhi)量用戶(hu)無(wu)法(fa)評(ping)價。結(jie)論;焊(han)接(jie)(jie)法(fa)蘭管(guan)因(yin)其焊(han)縫(feng)強(qiang)度低,脆性大(da)而經常發生(sheng)事故,雖不受(shou)用戶(hu)歡(huan)迎,但無(wu)更好的(de)替(ti)代產品,所以目前市場(chang)占有率還排(pai)在(zai)第一(yi)位。

二,螺紋(wen)法(fa)蘭(lan)管。顧(gu)名思(si)義法(fa)蘭(lan)與管是用螺紋(wen)連(lian)接(jie)的。這種連(lian)接(jie)方式軸向抗拉(la)強度尚可,但(dan)徑(jing)向強度低。因(yin)插(cha)口(kou)(kou)螺紋(wen)變(bian)形會造成接(jie)口(kou)(kou)漏(lou)水,大口(kou)(kou)徑(jing),地埋(mai)管均無(wu)法(fa)使用。因(yin)為受使用條件限制和接(jie)口(kou)(kou)密封不可靠(kao)等因(yin)素影響(xiang),也不受用戶歡迎。

三,砂(sha)型(xing)(xing)整鑄(zhu)(zhu)法(fa)蘭(lan)(lan)管(guan)。整鑄(zhu)(zhu)法(fa)蘭(lan)(lan)管(guan)目前多數采(cai)用(yong)普通砂(sha)型(xing)(xing)鑄(zhu)(zhu)造(zao)和(he)消失模鑄(zhu)(zhu)造(zao)。其(qi)中(zhong)普通砂(sha)型(xing)(xing)鑄(zhu)(zhu)造(zao)存在(zai)的(de)(de)(de)主要問(wen)題(ti)是(shi),管(guan)壁(bi)厚不(bu)均勻,彎曲變(bian)形(xing);消失模鑄(zhu)(zhu)造(zao)存在(zai)的(de)(de)(de)主要問(wen)題(ti)是(shi),夾渣,氣(qi)孔多,水(shui)壓試驗漏水(shui)率(lv)(lv)大。特別需要指出(chu)的(de)(de)(de)是(shi),管(guan)徑(jing)規格越小,長度(du)越長,存在(zai)上(shang)述(shu)缺陷的(de)(de)(de)幾率(lv)(lv)越大,dn200以下,長度(du)在(zai)2米以上(shang)的(de)(de)(de)法(fa)蘭(lan)(lan)管(guan)很(hen)(hen)難整鑄(zhu)(zhu)成型(xing)(xing),即便成型(xing)(xing),合格率(lv)(lv)也(ye)很(hen)(hen)低,無法(fa)滿足市場(chang)需求。如何規避上(shang)述(shu)幾種法(fa)蘭(lan)(lan)管(guan)的(de)(de)(de)缺陷,離心整體鑄(zhu)(zhu)造(zao)雙盤法(fa)蘭(lan)(lan)直(zhi)管(guan)是(shi)用(yong)戶迫切需求。因此,研制開發一(yi)種實型(xing)(xing)離心鑄(zhu)(zhu)造(zao)雙盤法(fa)蘭(lan)(lan)直(zhi)管(guan)及(ji)穿墻法(fa)蘭(lan)(lan)直(zhi)管(guan)的(de)(de)(de)設備及(ji)方法(fa)一(yi)直(zhi)是(shi)急待解決的(de)(de)(de)新(xin)課題(ti)。

所(suo)述的一種實型離心鑄造雙盤法(fa)蘭直(zhi)(zhi)管(guan)及穿墻法(fa)蘭直(zhi)(zhi)管(guan)的方法(fa)是(shi):

(1)模具準備

a、根據用(yong)戶(hu)需(xu)求,按不同規格(ge),不同壓(ya)力等級準備泡沫(mo)(mo)塑(su)料(liao)模(mo)(mo),選擇(ze)一(yi)型鑄造(zao)幾件(jian),因管模(mo)(mo)最大(da)有(you)效(xiao)長度為5.8米,在(zai)有(you)效(xiao)長度內可選擇(ze)單件(jian)或多件(jian)整體(ti)離心鑄造(zao),客戶(hu)需(xu)要兩(liang)件(jian)2.5米雙盤穿墻(qiang)法蘭管,將兩(liang)個件(jian)放在(zai)一(yi)個管模(mo)(mo)內,總長度不超過5.8米即(ji)可,泡沫(mo)(mo)塑(su)料(liao)模(mo)(mo)設(she)計為兩(liang)個半(ban)圓,便(bian)于包裹在(zai)定(ding)位鋼筒骨架上,泡沫(mo)(mo)塑(su)料(liao)模(mo)(mo)兩(liang)個半(ban)圓接縫用(yong)熱熔(rong)膠粘(zhan)接密封,用(yong)專用(yong)膠帶紙捆綁固定(ding)在(zai)定(ding)位鋼筒骨架上;

b、泡沫塑料模(mo)外表面需淋涂0.8-1.2㎜厚的(de)專用(yong)涂料,防止澆注過程中(zhong)鑄件表面粘(zhan)砂,涂料層(ceng)在60℃烘房中(zhong)烘干8小時,待涂料干燥后備用(yong);

c、根據(ju)鑄件規格選配管模,確保鑄件距管模內壁最小尺寸不(bu)低(di)于30㎜,兩端法(fa)蘭盤端面距壓板(ban)距離大于100㎜;檢查管模排(pai)氣孔是否通暢(chang),檢查管模端堵法(fa)蘭螺栓(shuan)緊固情(qing)況,檢查壓板(ban)、上端堵支撐環、壓板(ban)楔鐵(tie)是否完好,檢查就緒后安裝壓板(ban)、打緊壓板(ban)楔鐵(tie);

d、將管(guan)模垂(chui)直放入造(zao)型地坑內的震實臺上(shang),把烘(hong)干并在定位鋼筒骨架(jia)上(shang)的泡沫(mo)塑料模裝入管(guan)模的壓板定位孔,安(an)裝上(shang)端堵支撐環并鎖緊,開始充填(tian)樹脂砂操作;

(2)造型

a、充填樹脂(zhi)砂操作過程(cheng)稱(cheng)為造型,用連續混砂機混制樹脂(zhi)砂,從管(guan)模(mo)上方加入(ru)泡沫(mo)塑料模(mo)與(yu)管(guan)模(mo)內壁的縫隙(xi)中;

b、填滿樹脂(zhi)(zhi)砂(sha)后,啟動震實臺(tai)對樹脂(zhi)(zhi)砂(sha)震實,要求震實臺(tai)必須滿足高頻率(lv)低(di)振幅特點,既保證樹脂(zhi)(zhi)砂(sha)密實,又不能損壞(huai)泡沫塑料(liao)模;

c、充填樹(shu)脂砂(sha)操作結束并震實(shi)后,松(song)開壓(ya)(ya)板(ban)楔鐵(tie),取下(xia)上(shang)端(duan)堵支撐環(huan),將(jiang)多(duo)余的樹(shu)脂砂(sha)去掉(diao)并刮平,安(an)裝上(shang)壓(ya)(ya)板(ban),用壓(ya)(ya)板(ban)楔鐵(tie)鎖緊;

d、20分鐘后抽出定位(wei)鋼筒骨架,泡沫塑料模(mo)留在樹脂砂中(zhong)不用(yong)取出,澆注時自行燃燒掉;

e、將管模整體從地(di)坑中取(qu)出放平,以備離心(xin)澆注;
