\r產(chǎn)品介紹：<\/strong><\/span><\/span>\r<\/p>\r\r
\r<\/span><\/span>\r<\/div>\r\r機筒在擠出壓塑系統(tǒng)中和一樣，是擠出機的重要零件。機筒與螺桿配合工作，機筒包容螺桿，螺桿在機筒內(nèi)轉(zhuǎn)動。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r機筒與螺桿的正常配合工作，保證了擠出機的連續(xù)擠塑原料成型生產(chǎn)。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r產(chǎn)品結(jié)構(gòu)：<\/strong><\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r機筒的結(jié)構(gòu)比較簡單。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r在大型擠出機中，機筒的結(jié)構(gòu)可由幾段組成。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r由于機筒分為幾段組成，則每段機筒的長度縮小了，這給機械加工機筒帶來了方便。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r但是，這種由幾段組成的機筒，機械加工后的內(nèi)徑尺寸和幾段機筒的內(nèi)孔同心度精度比較難達(dá)到一致；<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r此外，分段機筒用法蘭連接，給機筒的加熱和冷卻設(shè)備布置也會帶來些難度，溫度控制也不會太均勻。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r為了節(jié)省較貴重的合金鋼材，有些大型擠出機的機筒采用內(nèi)孔加襯套或澆鑄耐磨合金層的方法。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r

\r這樣的機筒外套體可由普通鋼鑄造，達(dá)到降低機筒的制造費用的目的。<\/span><\/span>\r<\/p>\r
