樹脂(zhi)砂機床橫梁(liang)采用消失模鑄(zhu)(zhu)造工藝，消失模鑄(zhu)(zhu)造能夠鑄(zhu)(zhu)造各種(zhong)傳統鑄(zhu)(zhu)造方式難以完(wan)成的(de)幾何結構復雜的(de)大型鑄(zhu)(zhu)件(jian)(jian)、箱(xiang)體鑄(zhu)(zhu)件(jian)(jian)及(ji)殼體鑄(zhu)(zhu)件(jian)(jian)。
樹(shu)脂(zhi)(zhi)砂(sha)(sha)機(ji)(ji)床(chuang)橫梁的(de)(de)鑄(zhu)(zhu)(zhu)造(zao)(zao)方法一般(ban)采(cai)用(yong)(yong)消(xiao)失(shi)模(mo)鑄(zhu)(zhu)(zhu)造(zao)(zao)工藝，樹(shu)脂(zhi)(zhi)砂(sha)(sha)鑄(zhu)(zhu)(zhu)造(zao)(zao),實型鑄(zhu)(zhu)(zhu)造(zao)(zao),高牌號鑄(zhu)(zhu)(zhu)造(zao)(zao)等，例如機(ji)(ji)床(chuang)大(da)型鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)床(chuang)身(shen),立(li)柱,橫梁,滑臺等都是用(yong)(yong)這幾種鑄(zhu)(zhu)(zhu)造(zao)(zao)工藝。大(da)型鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)材質：HT200-350，可承接單件(jian)(jian)(jian)60噸左(zuo)右(you)的(de)(de)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)。采(cai)用(yong)(yong)樹(shu)脂(zhi)(zhi)砂(sha)(sha)型鑄(zhu)(zhu)(zhu)造(zao)(zao)大(da)型鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)優點：消(xiao)失(shi)模(mo)鑄(zhu)(zhu)(zhu)造(zao)(zao)對于生產單件(jian)(jian)(jian)或小批(pi)量的(de)(de)汽車覆(fu)蓋件(jian)(jian)(jian),機(ji)(ji)床(chuang)床(chuang)身(shen)等大(da)型鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)較有很大(da)優勢,表面質量好等優勢。
樹脂砂機床橫梁的(de)(de)結構復(fu)雜收(shou)(shou)(shou)縮(suo)困難，鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)收(shou)(shou)(shou)縮(suo)率(lv)減(jian)小(xiao)。例如，同(tong)一成(cheng)分澆注的(de)(de)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)鋼件(jian)(jian)(jian)，因(yin)結構形(xing)狀不同(tong)，其中(zhong)以自(zi)由收(shou)(shou)(shou)縮(suo)時的(de)(de)收(shou)(shou)(shou)縮(suo)率(lv)。大(da)型(xing)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)材料(liao)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)材料(liao)不同(tong)，鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)造(zao)收(shou)(shou)(shou)縮(suo)率(lv)也不同(tong)。例如，鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)鋼的(de)(de)收(shou)(shou)(shou)縮(suo)率(lv)比(bi)灰(hui)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)鐵(tie)大(da)；灰(hui)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)鐵(tie)中(zhong)硫多時，收(shou)(shou)(shou)縮(suo)率(lv)增大(da)，硅(gui)多時收(shou)(shou)(shou)縮(suo)率(lv)減(jian)小(xiao)。大(da)型(xing)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)退(tui)讓性鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)型(xing)的(de)(de)退(tui)讓性好(hao)，鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)收(shou)(shou)(shou)縮(suo)率(lv)增大(da)。例如，用(yong)濕(shi)性和(he)水玻璃砂型(xing)澆鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)的(de)(de)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)(jian)比(bi)干型(xing)澆鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)的(de)(de)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)收(shou)(shou)(shou)縮(suo)率(lv)大(da)。同(tong)樣(yang)道理，隨(sui)著鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)尺寸(cun)增大(da)，鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)型(xing)的(de)(de)退(tui)讓性變差，鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)收(shou)(shou)(shou)縮(suo)率(lv)也就減(jian)小(xiao)。
樹脂砂(sha)機(ji)床橫(heng)梁毛坯尺(chi)寸1910mm×960mm×1120mm,壁(bi)厚25mm,***小(xiao)壁(bi)厚15mm,重量為2100kg,材質為HT300,導軌(gui)淬(cui)火.采用(yong)呋(fu)喃樹脂砂(sha)造型,15t工頻感應電爐熔煉。水(shui)平床身(shen)配上傾(qing)(qing)斜放(fang)置(zhi)的(de)(de)滑板，并配置(zhi)傾(qing)(qing)斜式導軌(gui)防護罩(zhao)，這種布局(ju)形式一方面(mian)有水(shui)平床身(shen)工藝性好(hao)的(de)(de)特點，另(ling)一方面(mian)機(ji)床寬度方向的(de)(de)尺(chi)寸較水(shui)平配置(zhi)滑板的(de)(de)要小(xiao)，且排屑方便。水(shui)平床身(shen)配上傾(qing)(qing)斜放(fang)置(zhi)的(de)(de)滑板和斜床身(shen)配置(zhi)斜滑板布局(ju)形式被中、小(xiao)型數控(kong)車(che)床所普遍采用(yong)。
樹(shu)脂砂(sha)(sha)機床(chuang)橫梁的鑄(zhu)(zhu)造(zao)方(fang)法常用(yong)的是砂(sha)(sha)型(xing)(xing)鑄(zhu)(zhu)造(zao)，其次是特種鑄(zhu)(zhu)造(zao)方(fang)法，如：金屬型(xing)(xing)鑄(zhu)(zhu)造(zao)、熔(rong)模鑄(zhu)(zhu)造(zao)、石膏型(xing)(xing)鑄(zhu)(zhu)造(zao)等(deng)(deng)。而(er)砂(sha)(sha)型(xing)(xing)鑄(zhu)(zhu)造(zao)又可以分為粘(zhan)土砂(sha)(sha)型(xing)(xing)、粘(zhan)結劑砂(sha)(sha)型(xing)(xing)、樹(shu)脂自(zi)硬砂(sha)(sha)型(xing)(xing)、消(xiao)失模等(deng)(deng)等(deng)(deng)。
