Mandrel chishandiso chinoshandiswa mukugadzira mapaipi asina musono, ayo anopinzwa mukati memuviri wepombi uye anoumba gomba rakatenderera rine rollers kugadzira pombi. Mandrels anodiwa kuti arambe achitenderedza pombi, pombi oblique rolling yekuwedzera, periodic pombi kutenderedza, pombi yepamusoro, uye kutonhora kutenderedza uye kutonhora kudhirowa kwepombi.
Iyo Mandrel itsvimbo yakareba yakatenderedza iyo inotora chikamu mukushandurwa kwepombi zvinhu munzvimbo yedeformation, senge kumusoro. Musiyano ndewekuti panguva ye oblique rolling, iyo Mandrel inofamba axially mukati mepombi zvinhu sezvainotenderera; Munguva yekutenderera kwenguva refu (inoenderera mberi chubhu kutenderera, periodic chubhu kutenderedza, kumusoro chubhu), iyo Mandrel haitenderere asi zvakare inofamba axially nechubhu.
PaMandrel inoyangarara uye zvishoma inofamba Mandrel inoenderera pombi yekukungurusa muchina (ona inoenderera pombi inotenderedza muchina wekukungurusa pombi), iyo Mandrel chishandiso chakakosha. Pamusoro pekugadzirwa kwepamusoro-simba uye yakakwirira-inodzivirira kupfeka zvinhu, zvinodawo hupamhi hwepamusoro, sekukuya uye kurapwa kwekupisa mushure mekutendeuka. Iyo Mandrel inoyangarara yakareba kwazvo (kusvika 30m) uye inorema (kusvika 12t). Hurefu hweiyo inodzikamisa Mandrel ipfupi zvishoma, asi inoda yepamusoro yemhando yemhando. Iyo Mandrel inoshandiswa papombi yepamusoro inofanirwa kukwanisa kumira nesimba guru rekusundira. Iyo Mandrel yemuchina weperiodic pombi inotenderedza ine nguva yakareba yekupisa panguva yekushanda. Iwo maMandrels eiyo diagonal rolling uye kutambanudza muchina anosanganisira tension Mandrels, Mandrels anoyangarara, muganhu Mandrels, uye retraction Mandrels.
A tension Mandrel iMandrel inofamba axially nekumhanya kwakakura kudarika axial speed yepombi panguva yekushanda (ona pombi diagonal rolling extension), uye inoita kushushikana mukati memukati wepombi. The retreat type Mandrel iMandrel inofamba ichienda kune axial direction yechubhu, uye inoiswa post tension. Zvinodiwa zveMandrel zveiyo diagonal rolling uye kutambanudza muchina zvakaderera pane izvo zvelongitudinal rolling uye kutambanudza muchina.
Iyo Mandrel yakaganhurirwa ine akasiyana akakosha mashandisiro mukugadzirisa pombi, kunyanya inoratidzwa mune zvinotevera zvinhu:
l Kuvandudza kunaka kwemadziro:
Iyo shoma inofamba Mandrel rolling mill inovimbisa iko kurongeka kwepombi madziro ukobvu nekudzora kumhanya kweMandrel. Kumhanya kweMandrel kunofanirwa kunge kwakakwira kupfuura kumhanya kweiyo yekutanga furemu uye kuderera kupfuura kumhanya kweiyo yekutanga furemu, kuitira kuti urambe uchimhanyisa panguva yese yekukunguruka, kudzivirira kusarongeka kwekuyerera kwesimbi, uye kuderedza chiitiko. ye "bamboo knots".
l Kuvandudza kunaka kwepombi dzesimbi:
Nekuda kwekufamba kwehukama pakati peMandrel nemukati mepombi yesimbi, iyo shoma inofamba Mandrel rolling mill inobatsira pakuwedzera kwesimbi, inoderedza lateral deformation, uye inovandudza iko kurongeka kwemukati nekunze kwenzvimbo uye zviyero zve. pombi yesimbi.
l Kupfupisa maitiro ekuyerera:
Kuenzaniswa neinoyangarara Mandrel rolling mill, iyo shoma inofamba Mandrel rolling mill inobvisa muchina wekubvisa, inopfupisa kuyerera kwemaitiro, inowedzera tembiricha yekutenderera yepombi dzesimbi, uye inochengetedza simba.
