Kupanga ndondomeko ya seamless zitsulo chitoliro

Kupanga mapaipi azitsulo amphamvu kwambiri
Njira yopangira chitoliro chopanda chitsulo chosasunthika imagawidwa pang'onopang'ono munjira yodutsa (njira ya Mennesmann) ndi njira yotulutsira. Njira yodutsamo (njira ya Mennesmann) ndiyoyamba kutulutsa chubu popanda kanthu ndi chogudubuza, kenako ndikuchikulitsa ndi mphero. Njirayi ili ndi liwiro lopanga mwachangu, koma imafuna machinability apamwamba a chubu opanda kanthu, ndipo ndi oyenera kupanga machubu a zitsulo zamkati ndi aloyi otsika.

Njira yotulutsira ndikubowola chubu chopanda kanthu kapena ingot ndi makina oboola, kenako ndikuchitulutsa mu chitoliro chachitsulo ndi extruder. Njirayi ndi yocheperapo kuposa njira yopukutira skew ndipo ndiyoyenera kupanga mapaipi achitsulo amphamvu kwambiri.

Njira zonse ziwiri za skew rolling ndi extrusion ziyenera kutenthetsa chubu popanda kanthu kapena ingot, ndipo chubu chachitsulo chopangidwa chimatchedwa chubu chotentha. Mapaipi achitsulo opangidwa ndi njira zogwirira ntchito zotentha nthawi zina amatha kuzizira ngati pakufunika.

Pali njira ziwiri zogwirira ntchito zozizira: imodzi ndi njira yojambula yozizira, yomwe ndiyo kujambula chitoliro chachitsulo kupyolera mujambula kufa kuti pang'onopang'ono woonda ndi kukulitsa chitoliro chachitsulo;
Njira ina ndi yozizira yogudubuza, yomwe ndi njira yogwiritsira ntchito mphero yotentha yopangidwa ndi Mennesmann Brothers pogwira ntchito yozizira. Kuzizira kozizira kwa chitoliro chopanda chitsulo kumatha kusintha kulondola kwazithunzi ndi kumaliza kwa chitoliro chachitsulo, ndikuwongolera mawonekedwe amakina azinthuzo.

Njira yopangira chitoliro chopanda chitsulo chosasinthika (chitoliro chachitsulo chotentha)
Kusasunthika kwa chitoliro chachitsulo kumatsirizidwa makamaka ndi kuchepetsa kupsinjika, ndipo njira yochepetsera mikangano ndi njira yopititsira patsogolo yazitsulo zopanda pake popanda mandrel. Pansi pa chikhalidwe kuonetsetsa kuwotcherera khalidwe la chitoliro kholo, ndi kuwotcherera chitoliro kukokana kuchepetsa ndondomeko ndi kutentha welded chitoliro lonse kuti kuposa madigiri 950 Celsius, ndiyeno yokulungirani mu diameters osiyanasiyana akunja ndi makoma ndi chochepetsera mavuto (okwana 24 akudutsa wa kuchepetsa mavuto). Kwa mipope yokhuthala yomalizidwa, mapaipi achitsulo otenthetsera omwe amapangidwa ndi njirayi ndi osiyana kwambiri ndi mapaipi wamba omwe amawotcherera pafupipafupi. The yachiwiri mavuto kuchepetsa kugubuduza ndi kulamulira basi kulondola dimensional wa zitsulo chitoliro (makamaka roundness ndi khoma makulidwe kulondola kwa chitoliro thupi) bwino kuposa mipope ofanana msokonezo.
