\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，螺桿在機筒內轉動。<\/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)品結構：<\/strong><\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r機筒的結構比較簡單。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r在大型擠出機中，機筒的結構可由幾段組成。<\/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，機械加工后的內徑尺寸和幾段機筒的內孔同心度精度比較難達到一致；<\/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，達到降低機筒的制造費用的目的。<\/span><\/span>\r<\/p>\r
