管(guan)(guan)帽的成型(xing)方法：1.鍛壓法:用型(xing)鍛機將管(guan)(guan)子(zi)端(duan)部(bu)(bu)或一部(bu)(bu)分予以(yi)沖伸，使外徑減少，常用型(xing)鍛機有旋轉式(shi)、連(lian)桿式(shi)、滾(gun)輪式(shi).

　　2.滾軋法:一般不(bu)用(yong)(yong)芯軸(zhou)，適合于厚(hou)壁管(guan)內(nei)側(ce)圓緣.在管(guan)內(nei)放置(zhi)芯子(zi)，外(wai)周(zhou)用(yong)(yong)滾輪推壓，用(yong)(yong)于圓緣加(jia)工.沖壓法:在沖床上(shang)用(yong)(yong)帶錐度的芯子(zi)將(jiang)管(guan)端擴到要(yao)求的尺寸和形狀.

　　3.彎曲成形法:有三種(zhong)(zhong)(zhong)方(fang)(fang)法較為常用，一(yi)種(zhong)(zhong)(zhong)方(fang)(fang)法叫(jiao)伸展法，另一(yi)種(zhong)(zhong)(zhong)方(fang)(fang)法叫(jiao)沖壓法，第(di)三種(zhong)(zhong)(zhong)滾(gun)輪法，有3－4個(ge)(ge)輥，兩(liang)個(ge)(ge)固定輥，一(yi)個(ge)(ge)調(diao)(diao)整輥，調(diao)(diao)整固定輥距(ju)，成品(pin)管件就(jiu)是彎曲的.

　　4.鼓(gu)脹法(fa)(fa):一種(zhong)是在(zai)管(guan)內放(fang)置橡膠，上方用(yong)(yong)沖子(zi)(zi)壓縮，使管(guan)子(zi)(zi)凸出成(cheng)形；另一種(zhong)方法(fa)(fa)是液壓鼓(gu)脹成(cheng)形，在(zai)管(guan)子(zi)(zi)中部充入液體(ti)，液體(ti)壓力把管(guan)子(zi)(zi)鼓(gu)成(cheng)所需要的(de)(de)形狀(zhuang)，波紋管(guan)的(de)(de)生產大部分用(yong)(yong)的(de)(de)是這(zhe)種(zhong)方法(fa)(fa)

滄州金旭機械(xie)制造有限公(gong)司是國(guo)家的生產企業，主營碳鋼，不銹鋼，合金材質的封頭管(guan)帽，廠家以質量求發(fa)展 Q235.20#管(guan)帽批發(fa)價，以信(xin)譽贏得國(guo)內(nei)外用(yong)戶的*。

       變(bian)壁厚的(de)(de)，指(zhi)沿管(guan)(guan)子(zi)長(chang)度(du)方(fang)向使(shi)壁厚發生變(bian)化(hua)；管(guan)(guan)件(jian)(jian)的(de)(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)方(fang)法(fa)(fa)也(ye)有(you)良(liang)多(duo)種。良(liang)多(duo)還屬于機(ji)械加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)類的(de)(de)范疇，用的(de)(de)多(duo)的(de)(de)是(shi)(shi)(shi)沖(chong)壓(ya)法(fa)(fa)、鍛(duan)壓(ya)法(fa)(fa)、滾輪加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)法(fa)(fa)、滾軋法(fa)(fa)、鼓(gu)脹法(fa)(fa)、拉伸法(fa)(fa)、彎曲法(fa)(fa)、和組合加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)法(fa)(fa)。管(guan)(guan)件(jian)(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)是(shi)(shi)(shi)機(ji)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)和金(jin)屬壓(ya)力(li)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)的(de)(de)有(you)機(ji)結合。管(guan)(guan)件(jian)(jian)為什么(me)在國(guo)外(wai)發展(zhan)如此(ci)迅速(su)，管(guan)(guan)件(jian)(jian)產品(pin)有(you)兩個比(bi)(bi)較突出的(de)(de)優點：*是(shi)(shi)(shi)可代替部分(fen)機(ji)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)產品(pin)，而且比(bi)(bi)機(ji)械加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)件(jian)(jian)、鑄件(jian)(jian)、鍛(duan)造結構件(jian)(jian)重量(liang)輕(qing)，節約(yue)材料；二是(shi)(shi)(shi)比(bi)(bi)機(ji)械加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)產品(pin)節省(sheng)工(gong)(gong)序、工(gong)(gong)時，降低工(gong)(gong)件(jian)(jian)成本。擴(kuo)徑管(guan)(guan)件(jian)(jian)，按照要(yao)求將管(guan)(guan)件(jian)(jian)端部或某部位擴(kuo)大形(xing)成各種外(wai)形(xing)的(de)(de)管(guan)(guan)件(jian)(jian)；所以管(guan)(guan)件(jian)(jian)法(fa)(fa)在價上(shang)(shang)很有(you)優勢 管(guan)(guan)帽，將近降低了50%。從性(xing)能上(shang)(shang)講(jiang)，管(guan)(guan)件(jian)(jian)法(fa)(fa)要(yao)優于機(ji)械加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)法(fa)(fa)。
