Inoenderera mberi ichitenderedza chubhu (inozonzi MPM) maitiro mandrel inoreva kupfeka refu capillary koramu zvichienderera kuburikidza neyakatevedzana kuronga rack, kukungurutsa uye kutenderedza nzira inopindirana nekuve kukungurutsa pombi saizi zvinodiwa. Chimiro chayo chinosiyanisa hukuru hukuru, kushanda kwepamusoro, yakanaka kukungurusa isina pombi kureba uye chigadzirwa chemhando, yakakura saizi renji; asi mari yayo yakakura uye yakabatana tekinoroji uye otomatiki kudzora zvakanyanya kudiwa.

MPM rack yemhando mbiri-roll, chimiro chakafanana neyakajairwa kaviri rolling mill. Zvichienderana nekufamba kwe mandrel MPM inogona kukamurwa kuita inoyangarara uye semi stopper stopper mandrel mill matatu marudzi.

1970s pamberi peMPM shandisa yakazara-inoyangarara mandrel oparesheni. Kubva pa punch kusvika kunopinda capillary mushure mekunge mandrel apinda mupombi inokunguruka muchina, kukunguruka kana kukunguruka kweguyo kuri kumashure kudhonzera kumashure kune mandrel rollers, pane bhara rekudzima muchina kubva pakukunguruka nhengo ye mandrel yabviswa, ichikunguruka mukati. nhanho inotevera, uye akadzokera kune mandrel chigayo reception mushure mekutonhodza, pinda zvakare kutenderera kunotevera kwebasa.

1970s France neItaly vakaonekwa mune mandrel hafu chivharo uye chivharo cheMPM. Muchidimbu, nzira mbiri idzi dzekushanda pamushini we mandrel chubhu, inokweretwa kubva kune mandrel nzira yekushanda yemuchina-matatu-roll rolling machine.
Hafu yakachengetwa mandrel nzira yekushanda, iri mukati mekukunguruka, iyo mandrel yekufamba kumhanya ishoma, iyo kadhi inobata mandrel inosungirirwa kune isingasviki yakakungurutswa kumberi kumhanya kweiyo workpiece. Yakachengetwa mandrel nzira yekushanda, kunze kwekunge panguva yekukunguruka, iyo mandrel yekufamba kumhanya ishoma, tayi yapera mushure mekukunguruka, iyo mandrel neanobata kadhi akadhonzwa achidzokera kubasa rekutanga chinzvimbo.

Mumakore achangopfuura, iyo Y-yakaumbwa matatu-mupumburu MPM yakaratidza PQF chigayo, yakatevera kusawirirana-kuderedza tekinoroji kubva kune yechipiri roller kusvika kune matatu roller shanduko, saka rolling process rolling deformation mamiriro ekushushikana uye deformation kugovera, michina, magetsi emagetsi mutoro kugovera, rolling rusvingo ukobvu uye rusvingo ukobvu tolerances uye saka ane maviri-mupumburu chigayo unmatched zvakanakira. Yayo yakatsiga kukungurutswa kwaro inogona kuvandudzwa pombi mhiri-sectional dimension, yakaderera flange nharaunda kana mutswe Lin Wen chiitiko mumunda dzakatetepa-namadziro pombi uye kukungurutsa yakakwirira alloy pombi zvinochinjika uye upfumi.
