Kuchuluka kwa pini yotetezera kumayenera kutsimikiziridwa molingana ndi mphamvu yometa pamene yadzaza.Pazinthu za pini monga DIN1 ndi DIN7, chofunikira kwambiri ndikulondola kwambiri.Kulekerera kwa pini yamtundu wa cylindrical 8m6 ndi φ8m6 (+0.015/+0.006);kupatuka kwapamwamba ndi +0.015, kutsika kwapansi ndi +0.006;kukula kwa malire ndi φ8.015, kukula kwa malire ndi φ8.006, ndipo malo olekerera ndi 0.009.Kulekerera kwa chitsulo chosapanga dzimbiri cylindrical pini 10 h8 ndi φ10 h8 (0/-0.022), kupatuka kumtunda ndi 0, ndipo kutsika kwapansi ndi -0.022.Kukula kwakukulu kwa malire ndi φ10, kukula kwa malire ndi φ9.978, ndipo malo olekerera ndi 0.022.Ma pini nthawi zambiri amagwiritsidwa ntchito kulumikiza, kutseka mbali kapena poyika msonkhano, ndipo amathanso kugwiritsidwa ntchito ngati zida zachitetezo.Zikhomo za Cylindrical zimakhazikika m'mabowo mwa kusokoneza kukonza magawo, kufalitsa mphamvu, kapena kuchita ngati magawo oyika.Ma cylindrical pins ndi ma pini oyika omwe amagwiritsidwa ntchito kukonza malo achibale pakati pa magawo.Ndi gawo lofunikira lothandizira pophatikiza kukonza ndi kusonkhana.Zikhomo za Cylindrical nthawi zambiri zimapangidwa ndi chitsulo chapamwamba kwambiri cha carbon structural monga zopangira.Nthawi zambiri, zinthuzo zimakhala zambiri C35 ndi C45, koma chithandizo cha kutentha chimafunika.Kunyamula zitsulo kumasankhidwa pansi pa zofunikira zamphamvu.Chitsulo chosapanga dzimbiri chimapangidwa makamaka ndi zinthu 303 ndipo sichifuna chithandizo cha kutentha.Pini yotanuka ya cylindrical nthawi zambiri imakhala 65Mn.
Nangula ndi amitundu iyi:
(1) Bawuti yowonjezera nangula
Maboti owonjezera a nangula, omwe amatchedwa mabawuti okulitsa, amagwiritsa ntchito kusuntha kwa chulucho ndi pepala lokulitsa (kapena manja okulitsa) kulimbikitsa kukulitsa kwa pepala lokulitsa, kupanga mphamvu zowonjezera ndi zowonjezera ndi konkriti pakhoma la dzenje, ndikupanga kukoka kukana kudzera mukumeta ubweya wa ubweya.Chigawo chomwe chimazindikira kukhazikika kwa chidutswa cholumikizidwa.Maboti a nangula okulitsa amagawidwa kukhala mtundu wowongolera ma torque ndi mtundu wowongolera kutengera njira zosiyanasiyana zowongolera mphamvu pakukhazikitsa.Yoyamba imayendetsedwa ndi torque, ndipo yomalizayo imayendetsedwa ndi kusamuka.
(2) Nangula wa mtundu wa Reaming
Nangula wamtundu wa Reaming, womwe umatchedwa kuti reaming bolts kapena grooving bolts, akubwereranso ndikukonzanso konkire pansi pa dzenje lobowola, pogwiritsa ntchito makina olumikizirana pakati pa konkriti yonyamula pamwamba yomwe idapangidwa pambuyo pokonzanso ndi mutu wokulitsa wa bawuti ya nangula. ., chigawo chomwe chimazindikira kukhazikika kwa chidutswa cholumikizidwa.Maboti a nangula amagawika m'kukonzanso ndi kudzipangira okha molingana ndi njira zosiyanasiyana zopangiranso.Yoyamba ndi pre-grooving ndi reming ndi wapadera pobowola chida;bolt yomaliza ya nangula imabwera ndi chida, chomwe chimakhala chodzigudubuza ndikuyambiranso panthawi yoyika, ndipo grooving ndi kukhazikitsa zimamalizidwa nthawi imodzi.
(3) Maboti a nangula omangika
Zomangira za nangula zomangika, zomwe zimadziwikanso kuti ziboliboli zamankhwala, zomwe zimatchedwa ma bolts amankhwala kapena zomangira, zimapangidwa ndi zomatira zapadera zamankhwala (anchoring glue) kuti amamatire ndi kukonza zomangira ndi mipope yamkati mkati mwa mabowo obowola a magawo a konkire.Kumangirira ndi kutseka ntchito pakati pa zomatira ndi wononga ndi zomatira ndi khoma la dzenje la konkire kuti lizindikire chigawo chomwe chimamangiriridwa ku chidutswa cholumikizidwa.
(4) Kubzala mankhwala kwa tendons
Chomera chobzala mankhwala chimaphatikizapo zitsulo zopindika ndi ndodo zazitali, zomwe ndiukadaulo wolumikizana ndi nangula womwe umagwiritsidwa ntchito kwambiri m'mabwalo aukadaulo adziko langa.Nangula wa mipiringidzo yobzala mankhwala ndi yofanana ndi yomanga mabawuti a nangula, koma chifukwa kutalika kwa mipiringidzo yobzala mankhwala ndi zomangira zazitali sizochepa, ndizofanana ndi kukhazikika kwa mipiringidzo ya konkriti, ndi mawonekedwe owonongeka. ndi yosavuta kuwongolera, ndipo nthawi zambiri imatha kuwongoleredwa ngati kuwonongeka kwa mipiringidzo ya nangula.Chifukwa chake, ndiyoyenera kulumikizana ndi ma anchorage a mamembala omangika kapena osakhazikika omwe mphamvu zawo zokhazikika komanso zolimba za seismic ndizochepera kapena zofanana ndi 8.
(5) Zomangira konkriti
Mapangidwe ndi makina okhazikika a zomangira za konkriti ndizofanana ndi zomangira zamatabwa.Njira yapadera imagwiritsidwa ntchito pogubuduza ndi kuzimitsa wononga zolimba ndi zakuthwa za ulusi wa mpeni.Pakuyika, dzenje lolunjika lokhala ndi mainchesi ang'onoang'ono limabowoleredwa kale, ndiyeno phula limakulungidwa, pogwiritsa ntchito ulusi ndi dzenje.Kuchita kwa occlusal pakati pa khoma konkire kumatulutsa mphamvu yokoka ndikuzindikira chigawo chomwe chimamangiriridwa ku mbali zogwirizanitsa.
(6) Kuombera misomali
Msomali wowombera ndi mtundu wa misomali yachitsulo yolimba kwambiri, kuphatikizapo zomangira, zomwe zimayendetsedwa ndi mfuti, mu konkire, ndikugwiritsa ntchito kutentha kwake (900 ° C) kupanga misomali yachitsulo ndi konkire yophatikizidwa chifukwa cha kusakanikirana kwa mankhwala ndi kugwedeza.Zindikirani anangula wa magawo ogwirizana.
