\r產(chǎn)品介紹：<\/strong><\/span><\/span>\r<\/p>\r\r
\r<\/span><\/span>\r<\/div>\r\r機(jī)筒在擠出壓塑系統(tǒng)中和一樣，是擠出機(jī)的重要零件。機(jī)筒與螺桿配合工作，機(jī)筒包容螺桿，螺桿在機(jī)筒內(nèi)轉(zhuǎn)動(dòng)。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r機(jī)筒與螺桿的正常配合工作，保證了擠出機(jī)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(jī)筒的結(jié)構(gòu)比較簡(jiǎn)單。<\/span><\/span>\r<\/div>\r\r
\r<\/span><\/span>\r<\/div>\r\r在大型擠出機(jī)中，機(jī)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(jī)筒分為幾段組成，則每段機(jī)筒的長(zhǎng)度縮小了，這給機(jī)械加工機(jī)筒帶來(lái)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(jī)筒，機(jī)械加工后的內(nèi)徑尺寸和幾段機(jī)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(jī)筒用法蘭連接，給機(jī)筒的加熱和冷卻設(shè)備布置也會(huì)帶來(lái)些難度，溫度控制也不會(huì)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(jī)的機(jī)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(jī)筒外套體可由普通鋼鑄造，達(dá)到降低機(jī)筒的制造費(fèi)用的目的。<\/span><\/span>\r<\/p>\r
