style="font-size:22px;">彎頭機(jī)制造彎頭的工藝流程：彎頭適用于管道轉(zhuǎn)彎處的一種管件。在管道系統(tǒng)所使用的全部管件中，所占比例最大。約為80%通常，對不同材料或博后的彎頭選用不同的成形工藝。制造廠常用的無縫彎頭成形工藝有熱推，從牙，擠壓等。熱推彎頭成形工藝是采用專用的彎頭機(jī)，洗榜和加熱裝置，使套在模具上的坯料在彎頭機(jī)的推動下向前運(yùn)動，在運(yùn)動中被加熱，擴(kuò)徑并彎曲成形的過程。熱推彎頭的變形特點(diǎn)是根據(jù)金屬材料塑性變形前后體積不變的規(guī)律確定管坯的直徑，多采用的管坯直徑小于彎頭直徑，通過芯?？刂婆髁系淖冃芜^程，是內(nèi)弧處被壓縮的金屬流動，補(bǔ)償?shù)揭驍U(kuò)徑而減薄的其它部位，從而得到壁厚均勻的彎頭。</span></div>
