樹(shu)脂砂機(ji)床(chuang)橫梁采用消失模(mo)(mo)鑄(zhu)(zhu)造(zao)工藝(yi)，消失模(mo)(mo)鑄(zhu)(zhu)造(zao)能(neng)夠鑄(zhu)(zhu)造(zao)各種傳統鑄(zhu)(zhu)造(zao)方式難以完成的幾何結(jie)構復雜的大型鑄(zhu)(zhu)件(jian)、箱體鑄(zhu)(zhu)件(jian)及殼(ke)體鑄(zhu)(zhu)件(jian)。
樹脂(zhi)砂機床(chuang)橫(heng)梁(liang)的鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)造方法一般采用消(xiao)失模(mo)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)造工(gong)藝(yi)，樹脂(zhi)砂鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)造,實型鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)造,高牌號鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)造等，例如機床(chuang)大(da)(da)型鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)的床(chuang)身(shen),立柱,橫(heng)梁(liang),滑臺等都是用這幾種鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)造工(gong)藝(yi)。大(da)(da)型鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)材質(zhi)(zhi)：HT200-350，可承接單件(jian)(jian)60噸左(zuo)右的鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)。采用樹脂(zhi)砂型鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)造大(da)(da)型鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)的優點：消(xiao)失模(mo)鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)造對于生產(chan)單件(jian)(jian)或小(xiao)批量(liang)的汽車覆蓋(gai)件(jian)(jian),機床(chuang)床(chuang)身(shen)等大(da)(da)型鑄(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)較有很大(da)(da)優勢(shi),表(biao)面質(zhi)(zhi)量(liang)好等優勢(shi)。
樹脂砂機床橫梁的(de)(de)(de)結構(gou)復雜(za)收(shou)(shou)(shou)(shou)(shou)縮(suo)困難(nan)，鑄(zhu)(zhu)件(jian)的(de)(de)(de)收(shou)(shou)(shou)(shou)(shou)縮(suo)率(lv)(lv)減(jian)小(xiao)。例(li)如，同(tong)(tong)一成分澆注(zhu)的(de)(de)(de)鑄(zhu)(zhu)鋼(gang)件(jian)，因結構(gou)形(xing)狀不(bu)同(tong)(tong)，其中(zhong)以自(zi)由收(shou)(shou)(shou)(shou)(shou)縮(suo)時的(de)(de)(de)收(shou)(shou)(shou)(shou)(shou)縮(suo)率(lv)(lv)。大(da)型鑄(zhu)(zhu)件(jian)的(de)(de)(de)材(cai)料(liao)(liao)鑄(zhu)(zhu)件(jian)的(de)(de)(de)材(cai)料(liao)(liao)不(bu)同(tong)(tong)，鑄(zhu)(zhu)造收(shou)(shou)(shou)(shou)(shou)縮(suo)率(lv)(lv)也不(bu)同(tong)(tong)。例(li)如，鑄(zhu)(zhu)鋼(gang)的(de)(de)(de)收(shou)(shou)(shou)(shou)(shou)縮(suo)率(lv)(lv)比(bi)灰鑄(zhu)(zhu)鐵大(da)；灰鑄(zhu)(zhu)鐵中(zhong)硫多時，收(shou)(shou)(shou)(shou)(shou)縮(suo)率(lv)(lv)增大(da)，硅多時收(shou)(shou)(shou)(shou)(shou)縮(suo)率(lv)(lv)減(jian)小(xiao)。大(da)型鑄(zhu)(zhu)件(jian)的(de)(de)(de)退(tui)讓(rang)(rang)性(xing)鑄(zhu)(zhu)型的(de)(de)(de)退(tui)讓(rang)(rang)性(xing)好，鑄(zhu)(zhu)件(jian)的(de)(de)(de)收(shou)(shou)(shou)(shou)(shou)縮(suo)率(lv)(lv)增大(da)。例(li)如，用濕性(xing)和水玻璃(li)砂型澆鑄(zhu)(zhu)的(de)(de)(de)鑄(zhu)(zhu)件(jian)比(bi)干型澆鑄(zhu)(zhu)的(de)(de)(de)鑄(zhu)(zhu)件(jian)的(de)(de)(de)收(shou)(shou)(shou)(shou)(shou)縮(suo)率(lv)(lv)大(da)。同(tong)(tong)樣道理，隨著鑄(zhu)(zhu)件(jian)的(de)(de)(de)尺寸增大(da)，鑄(zhu)(zhu)型的(de)(de)(de)退(tui)讓(rang)(rang)性(xing)變差，鑄(zhu)(zhu)件(jian)的(de)(de)(de)收(shou)(shou)(shou)(shou)(shou)縮(suo)率(lv)(lv)也就(jiu)減(jian)小(xiao)。
