Mandrel ndi chida chomwe chimagwiritsidwa ntchito popanga mapaipi opanda msoko, omwe amalowetsedwa mkati mwa thupi la chitoliro ndikupanga dzenje lozungulira ndi odzigudubuza kuti apange chitoliro. Mandrels amafunikira pakugudubuza chitoliro mosalekeza, kupitilira kwa chitoliro cha chitoliro, kugudubuza chitoliro pafupipafupi, chitoliro chapamwamba, kugudubuza kozizira komanso kujambula mapaipi ozizira.
Mandrel ndi ndodo yayitali yozungulira yomwe imatenga nawo gawo pakuwonongeka kwa chitoliro m'dera la deformation, monga pamwamba. Kusiyanitsa ndiko kuti panthawi yopukutira oblique, Mandrel amasuntha axially mkati mwa chitoliro pamene akuzungulira; Pakugudubuza kwautali (kugudubuzika kwa chubu, kugudubuza kwa chubu nthawi zonse, chubu chapamwamba), Mandrel sazungulira komanso amayenda mozungulira ndi chubu.
Pa Mandrel yoyandama komanso kuyenda kochepa Mandrel makina opitilira chitoliro (onani makina opitilira chitoliro ogubuduza chitoliro), Mandrel ndi chida chofunikira. Kuphatikiza pa kupangidwa ndi zida zamphamvu kwambiri komanso zodzikongoletsera, zimafunikiranso mawonekedwe apamwamba, monga kugaya ndi chithandizo cha kutentha pambuyo potembenuka. Mandrel woyandama ndi wautali kwambiri (mpaka 30m) komanso wolemera (mpaka 12t). Kutalika kwa malire a Mandrel ndiwafupikitsa pang'ono, koma kumafunikira zinthu zapamwamba kwambiri. Mandrel omwe amagwiritsidwa ntchito pa chitoliro chapamwamba ayenera kupirira mphamvu yaikulu yokankhira. The Mandrel wa periodic pipe rolling machine ali ndi nthawi yotentha yotentha panthawi yogwira ntchito. Ma Mandrels a makina ozungulira ndi otambasula akuphatikiza ma Mandrels, ma Mandrels oyandama, malire a Mandrels, ndi Mandrels obweza.
Kuthamanga kwa Mandrel ndi Mandrel omwe amayenda mothamanga kwambiri kuposa liwiro la axial la chitoliro panthawi yogwira ntchito (onani chitoliro chotambasula chotambasula), ndipo chimakhala chovuta pakatikati pa chitoliro. Mtundu wobwerera wa Mandrel ndi Mandrel womwe umayenda mosiyana ndi njira ya axial ya chubu, ndipo umakhala wovuta kwambiri. Zofunikira za Mandrel za makina ozungulira ndi otambasula ndi otsika kusiyana ndi makina ozungulira komanso otambasula.
Mandrel woletsedwa ali ndi ntchito zosiyanasiyana zofunika pakugudubuza mapaipi, makamaka akuwonetsedwa pazinthu izi:
l Kupititsa patsogolo makulidwe a khoma:
The zochepa zoyenda Mandrel anagubuduza mphero amaonetsetsa kulondola kwa chitoliro khoma makulidwe ndi kulamulira liwiro la Mandrel. Liwiro la Mandrel liyenera kukhala lalitali kuposa liwiro loluma la chimango choyamba komanso kutsika kuposa kuthamanga kwa chimango choyamba, kuti mukhale ndi liwiro lokhazikika panthawi yonse yogubuduza, kupewa kusakhazikika kwachitsulo, ndikuchepetsa zochitikazo. za "nsonga za bamboo".
l Kupititsa patsogolo ubwino wa mapaipi achitsulo:
Chifukwa cha kuyenda wachibale pakati pa Mandrel ndi pamwamba pamwamba pa chitoliro zitsulo, zochepa zoyenda Mandrel anagubuduza mphero ndi abwino kuwonjezera zitsulo, amachepetsa mapindikidwe ofananira nawo, ndi bwino kulondola kwa mkati ndi kunja pamwamba ndi miyeso ya chitoliro chachitsulo.
l Kufupikitsa mayendedwe:
Poyerekeza ndi mphero yoyandama ya Mandrel, mphero yocheperako ya Mandrel imachotsa makina ovundukula, ifupikitsa njirayo, imawonjezera kutentha komaliza kwa mipope yachitsulo, ndikupulumutsa mphamvu.
