Kupedzisa kwepaipi dzesimbi inzira inokosha uye inokosha yekubvisa kukanganisa mumapombi esimbi, kuwedzera kuwedzera kunaka kwepombi dzesimbi, uye kusangana nezvinodiwa zvekushandiswa kwakakosha kwezvigadzirwa. Steel pombi kupera kunonyanya kusanganisira: simbi pombi kutwasanuka, kupera kwekucheka ( chamfering, saizi), kuongorora uye kuongorora (kusanganisira pamusoro pemhando yekuongorora, geometric dimension yekuongorora, isingaparadze bvunzo uye hydraulic test, nezvimwewo), kukuya, kuyerwa kwehurefu, kuyera, kupenda, kudhinda uye kurongedza maitiro.Mamwe-akakosha-chinangwa mapombi esimbi anodawo pamusoro pepfuti kuputika, mechanic processing, anti-corrosion kurapwa, nezvimwe.
(I) Simbi pombi kururamisa kuremara uye kudzivirira kwavo
⒈ Chinangwa chekugadzirisa pombi yesimbi:
① Bvisa kukotama (kusiri kutwasuka) kunogadzirwa nepombi yesimbi panguva yekukunguruka, kutakura, kupisa kupisa uye kutonhora maitiro.
② Deredza ovality yepombi dzesimbi
⒉ Hunhu husina kunaka hunokonzerwa nepombi yesimbi panguva yekururamisa: inoenderana nemuchina wekururamisa modhi, chimiro chegomba, kugadzirisa kwegomba uye maitiro epombi yesimbi.
⒊ Hunhu hurema mune simbi pombi kutwasanudza: simbi pombi hadzina kutwasanudzwa (pombi kupera bends), dented, squared, kuputika, kukwenya kwepamusoro uye indentations, nezvimwe.
(ii) Simbi pombi kukuya uye kucheka kuremara uye kudzivirira kwavo
⒈ Chinangwa chekukuya zvirema zvepombi dzesimbi: kubvisa kuremara kwepamusoro kunotenderwa kuvapo nemhando dzepombi dzesimbi asi kunofanirwa kucheneswa kuti kunatsiridza kunaka kwepombi dzesimbi.
2. Kukanganisa kunokonzerwa nekukuya kwepamusoro kwepombi dzesimbi: Chikonzero chikuru ndechekuti kudzika uye chimiro chezvibodzwa zvekukuya mushure mekugaya zvinodarika zvinodiwa zvinotsanangurwa muyero, zvichiita kuti dhayamita rekunze nekukora kwemadziro epombi yesimbi ipfuure kutsauka kwakashata. kana kuva nechimiro chisina kujairika.
⒊ Simbi pombi kukuya kunofanirwa kuzadzisa zvinotevera zvinodiwa:
① Mushure mekuremara kwepamusoro kwepombi yesimbi yagadziriswa, ukobvu hwemadziro enzvimbo yakagadziriswa haigone kuve yakaderera pane kutsauka kwakashata kweiyo zita remadziro ukobvu hwepombi yesimbi, uye dhayamita rekunze renzvimbo yakagadziriswa rinofanira kusangana nezvinodiwa zve. kunze dhayamita yepombi yesimbi.
②Mushure mepamusoro pepombi yesimbi yavhurika, zvinodikanwa kuchengetedza pasi pepombi yesimbi seyakatsetseka yakakomberedzwa (yakawandisa arc).Hudzamu hwekukuya: hupamhi: kureba = 1:6:8
③ Kana uchikuya pombi yesimbi sese, hapafanirwe kuve nekupisa kana kujeka mavanga epolygonal pamusoro pepombi yesimbi.
④Iyo nzvimbo yekukuya pamusoro pepombi yesimbi haifaniri kudarika nhamba yakataurwa muyero.
⒋ Kukanganisa kukuru kunokonzerwa nekucheka kwepombi yesimbi kunosanganisira: kumagumo kwepombi yesimbi haina kumira, kune mabhura uye zvishwe, uye bevel angle haina kururama, nezvimwe.
⒌ Kuvandudza kutwasuka kwepombi yesimbi uye kuderedza ovality yepombi yesimbi ndizvo zvinodiwa kuti uve nechokwadi chekucheka kwepombi yesimbi.Kune mapaipi esimbi ane alloy yakakwira, kucheka kwemurazvo kunofanirwa kudziviswa zvakanyanya sezvinobvira kuderedza kuitika kwekutsemuka kwepombi kupera.
(iii) Simbi pombi pamusoro pekugadzirisa kukanganisa uye kudzivirira kwavo
⒈ Simbi pombi kugadziridzwa kwepamusoro kunonyanya kusanganisira: kupfurwa kwepamusoro peening, kukuya kwese kwepamusoro uye kugadzirisa kwemuchina.
⒉ Chinangwa: Kuwedzera kuvandudza kunaka kwepamusoro uye kurongeka kwepaipi yesimbi.
⒊ Zvishandiso zvekukuya kwese kwekunze kwepombi dzesimbi zvinonyanya zvinosanganisira: mabhandi abrasive, mavhiri ekukuya uye maturusi emuchina wekukuya.Mushure mekukuya kwese kwepasi pombi yesimbi, chiyero che oxide chiri pamusoro pepombi yesimbi chinogona kubviswa zvachose, kupera kwepamusoro kwepombi yesimbi kunogona kuvandudzwa, uye pamusoro pepombi yesimbi inogonawo kubviswa.Zvimwe zvikanganiso zvidiki senge madiki madiki, mitsetse yebvudzi, makomba, zvikwambo, nezvimwe.
① Shandisa bhandi rinokwenya kana vhiri rekukuya kuti unyatsokuya pamusoro pepombi yesimbi.Hurema hwemhando yepamusoro hunogona kuguma hunosanganisira: ganda dema pamusoro pepombi yesimbi, kukora kwemadziro akawandisa, nzvimbo dzakati sandara (mapolygoni), makomba, kutsva uye mavanga ekupfeka, nezvimwe.
② Ganda dema riri pamusoro pepombi yesimbi inokonzerwa nehuwandu hwekukuya hushoma kana makomba ari pamusoro pepombi yesimbi.Kuwedzera chiyero chekukuya kunogona kubvisa ganda dema pane simbi pombi pamusoro.
③ Iyo simbi yepombi madziro ukobvu haugone kushivirira nekuti kutsauka kwakashata kwemudhuri wepaipi pombi pachayo kwakakurisa kana kuwanda kwekukuya kwakakurisa.
④ Kupisa pamusoro pepombi yesimbi kunonyanya kukonzerwa nekunyanya kusangana kushushikana pakati pevhiri rekukuya nepamusoro pepombi yesimbi, kuwanda kwepombi yesimbi mukukuya kumwe, uye vhiri rekukuya rinoshandiswa rakanyanya.
⑤ Kuderedza kuwanda kwepombi yesimbi inokuya panguva imwe chete.Shandisa vhiri rekukuya pakuita rough papombi yesimbi uye vhiri rekukuya zvakanaka.Izvi hazvigoni kudzivirira kupisa kwepamusoro papombi yesimbi, asiwo kuderedza zvipfeko zvinogadzirwa pamusoro pepombi yesimbi.
⒋ Shot peening pamusoro pesimbi pombi pamusoro
① Simbi pombi pamusoro pekupfurwa kupeening ndeyekupfapfaidza simbi pfuti kana jecha requartz reimwe saizi pamusoro pepombi yesimbi nekumhanya kukuru kugogodza kubva pachikero cheoxide pamusoro kuti ivandudze kutsvedzerera kwepombi yesimbi.
②Kukura uye kuoma kwejecha kupfura uye kumhanya kwejekiseni zvinhu zvakakosha zvinokanganisa kunaka kwepfuti yakadongorera pamusoro pepombi yesimbi.
⒌ Simbi pombi pamusoro machining
①Mamwe mapombi esimbi ane yepamusoro mukati uye kunze kwepamusoro pemhando zvinodiwa zvinoda mechanic processing.
②Kurongeka kwedimensional, kunaka kwepamusoro uye kukombama kwepombi dzakagadzirwa hazvienzaniswi nemapombi anokungurutswa.
Muchidimbu, kupedzisa muitiro unokosha uye wakakosha zvikuru kuti uve nechokwadi chemhando yepombi dzesimbi.Kusimbisa basa rekupedzisa kupedzisa pasina mubvunzo richabatsira kuwedzera kunaka kwepombi dzesimbi.
