Intshayelelo kunye nesicelo seMandrel

I-Mandrel sisixhobo esisetyenziselwa ukuveliswa kwemibhobho engenamthungo, efakwe ngaphakathi ngaphakathi komzimba wombhobho kwaye yenza umngxuma ojikelezayo onama-roller ukubumba umbhobho. I-mandrels iyadingeka ukuze kuqhutywe umbhobho oqhubekayo, i-pipe oblique oblique extension extension, i-periodic pipe rolling, i-top pipe, kunye ne-cold rolling kunye nomzobo obandayo wemibhobho.

I-Mandrel yintonga ejikelezayo ende ethatha inxaxheba kwi-deformation yezinto zombhobho kwindawo yokuguqula, njengendawo ephezulu. Umahluko kukuba ngexesha le-oblique rolling, i-Mandrel ihamba nge-axially ngaphakathi kwezinto zombhobho njengoko ijikeleza; Ngexesha lokuqengqeleka kwe-longitudinal (i-tube eqhubekayo, i-tube periodic rolling, i-tube ephezulu), i-Mandrel ayijikelezi kodwa ihamba nge-axially kunye ne-tube.

Kwi-Mandrel edadayo kunye nentshukumo elinganiselweyo yeMandrel eqhubekayo umatshini wokuqengqeleka kombhobho (jonga umatshini wokuqengqeleka oqhubekayo wokuqengqeleka kombhobho), iMandrel sisixhobo esibalulekileyo. Ngaphandle kokwenziwa kwezinto eziphezulu eziphezulu kunye nezixhobo eziphezulu zokugqoka, nazo zifuna umgangatho ophezulu wendawo, njengokugaya kunye nokunyanga ukushisa emva kokujika. IMandrel edadayo inde kakhulu (ukuya kuthi ga kwi-30m) kwaye inzima (ukuya kuthi ga kwi-12t). Ubude bokunciphisa iMandrel bufutshane kancinci, kodwa bufuna umgangatho ophezulu wezinto eziphathekayo. I-Mandrel esetyenziselwa umbhobho ophezulu kufuneka ikwazi ukumelana namandla amakhulu okutyhala. I-Mandrel ye-periodic pipe rolling machine inexesha elide lokufudumeza ngexesha lokusebenza. I-Mandrels ye-diagonal rolling kunye nomatshini wokolula ibandakanya i-tension Mandrels, i-Mandrels edadayo, i-Mandrels umda, kunye ne-retraction Mandrels.

I-tension Mandrel yi-Mandrel ehamba nge-axially ngesantya esikhulu kune-axial yesantya sombhobho ngexesha lokusebenza (jonga i-pipe diagonal rolling extension), kwaye yenza uxinzelelo kumhlaba ongaphakathi wombhobho. Uhlobo lokuhlehla lweMandrel yiMandrel ehambela kwelinye icala ukuya kwicala le-axial letyhubhu, kwaye iphantsi koxinzelelo lweposi. Iimfuno zeMandrel ze-diagonal rolling kunye nomatshini wokwelula ziphantsi kunezo ze-longitudinal rolling and stretching machine.

I-Mandrel ethintelweyo inosetyenziso olwahlukeneyo olubalulekileyo kwinkqubo yokuqengqeleka kwemibhobho, ebonakaliswa ikakhulu kule miba ilandelayo:

l Ukuphucula ukuchaneka kobukhulu bodonga:

I-motion limited Mandrel rolling mill iqinisekisa ukuchaneka kodonga lombhobho ngokulawula isantya seMandrel. Isantya seMandrel kufuneka sibe phezulu kunesantya sokuluma sesakhelo sokuqala kwaye sibe sezantsi kunesantya sokuqengqeleka sesakhelo sokuqala, ukuze kugcinwe isantya esingaguqukiyo kuyo yonke inkqubo yokuqengqeleka, kunqande ukungahambi kakuhle kokuhamba kwesinyithi, kunye nokunciphisa isiganeko. ye "bamboo knots".

l Ukuphucula umgangatho wemibhobho yentsimbi:

Ngenxa yentshukumo ehambelanayo phakathi kweMandrel kunye nomgangatho ongaphakathi wombhobho wentsimbi, intshukumo encinci yeMandrel rolling mill ilungele ukwandiswa kwesinyithi, inciphisa ukuguqulwa kwecala, kwaye iphucula ukuchaneka kwendawo yangaphakathi nangaphandle kunye nemilinganiselo yentsimbi. umbhobho wentsimbi.

l Nciphisa inkqubo yokuhamba:

Xa kuthelekiswa ne-Mandrel rolling mill edadayo, intshukumo encinci yeMandrel rolling mill isusa umatshini wokuhluba, yenza mfutshane ukuhamba kwenkqubo, inyuse ubushushu bokugqibela bemibhobho yentsimbi, kwaye igcine amandla.
