Ibhodi ejingayo Z uhlobo lwe-clevis sisidibaniso sehardware esixhaphake kakhulu kurhwebo lwangaphandle. Zingasetyenziselwa ukuxhoma, ukulungisa, kunye nokulayisha{1}}imeko ezalanayo. Ngexesha lemveliso, siya kuhlangabezana nokuthembeka kokusebenza kwemveliso ngaxeshanye, imigangatho yemarike yamazwe ngamazwe, kunye neenkcukacha zokwenziwa ngokwezifiso kwabathengi ukuhlangabezana neemfuno zabathengi bethu bangaphandle.
Izinto eziphathekayo: E-China, ngokuqhelekileyo sikhetha umgangatho we-Q235, kodwa xa sithumela e-United States, sikhetha umgangatho we-A36, kwaye xa sithumela eYurophu, sikhetha umgangatho we-S235JR. Xa sithumela ngaphandle kwiindawo eziselunxwemeni, siphinda sikhethe intsimbi engenasici. Sineemfuno ezingqongqo zeempawu zokusebenza, kuqukwa amandla okuqina Amakhulu kuno okanye alingana ne-370MPa kunye namandla esivuno Amakhulu okanye alingana nama-235MPa ukuqinisekisa umthamo wokuthwala{7}}. Ngensimbi engenasici, sifuna i-Cr Enkulu kune-18% okanye ilingana ne-18%, i-Ni Enkulu kune-8% okanye ilingana ne-8%, kunye ne-316 insimbi engenasici iqulethe i-Mo Greater okanye ilingana ne-2% yokuqinisekisa ukuxhathisa ukubola, ukuqinisekisa ukusebenza kwemveliso evela kumthombo.
Uyilo loLwakhiwo: Ubume bebhodi ejingayo ye-Z uhlobo lwe-clevis luya kuchaphazela amava omsebenzisi. Ububanzi bokuvula hook kufuneka ilawulwe ngaphakathi ± 0.2mm. Ukusetyenziswa ngokuchanekileyo, kunokulawulwa ngaphakathi kwe-± 0.1mm ngokweemfuno zomsebenzisi. Ubukhulu bepleyiti buyilelwe ukuba bube yi-2-10mm ngokomthwalo{11}}ngokuthwala iimfuno, kunye nokunyamezela ipleyiti yobunzima be ±0.15mm. Ukunyamezela umngxuma ojingayo yi-H13, ukutenxa kwisithuba somngxuma Ngaphantsi okanye ilingana no-0.2mm, udonga lomngxuma lukhululekile, kwaye i-chamfer iKhulu okanye ilingana ne-0.5×45 degree. Ukuthwala umthwalo okhuselekileyo, kufuneka kwakhona ihlangabezane neemfuno zokwenene zomsebenzisi.
Imigangatho yobukhulu: Umgaqo wokunyamezela owamkelwe ngamazwe ngamazwe yi-ISO 8015, ukuthunyelwa kwe-United States kulandela i-ANSI B4.2, ukuthunyelwa kwi-European Union kulandela i-EN ISO 286, kunye nokuthunyelwa kwe-Japan kulandela i-JIS B 0401. Kubathengi abafuna ukulungiswa, silandela ngokungqongqo imizobo ebonelelwa ngumthengi ukuqinisekisa ukwaneliseka kwabathengi.
Iimfuno zenkqubo: Xa usika izinto eziphathekayo, qinisekisa ukuba ukusika kusicaba, i-burr{0}}ikhululekile kwaye i-deformation{1}}ikhululekile, ukunyamezela i-angle yokugoba yi-± 1 idigri, akukho zintanda okanye imibimbi kwi-bend, kwaye i-weld ayinayo i-porosity, i-slag inclusions kunye nokungena okungaphelelanga. Izinto eziphathekayo ziphathwa ngokucinywa kunye nokufudumala.
Zeziphi iinkqubo zonyango kumphezulu ezifunekayo kwibhodi ejingayo Z uhlobo clevis phambi kokuthumela ngaphandle? Ngokwenyani, zininzi iinkqubo zonyango lomphezulu, kwaye imveliso kufuneka ilungiselelwe ngokweemfuno zomsebenzisi. Unyango lomphezulu olwahlukileyo luneemeko ezahlukeneyo ezisebenzayo kunye nemigangatho yokubulawa. Ngezantsi, siza kubazisa ngokweenkcukacha:
| Iindlela zonyango zomphezulu | Iimeko ezisebenzayo | ImiGangatho yokuPhumeza | Iimfuno zokusebenza |
| Kushushu-dip gavanizing | Ngaphandle, iindawo ezimanzi | ISO 1461 (International), ASTM A123 (USA), EN ISO 1461 (EU) | Ubungqingqwa be-zinc yokwambathisa bukhulu kuno okanye bulingana ne-85μm, ukuncamathela kuKhulu okanye kuyalingana ne-3.5N/mm², kwaye ubude bexesha lovavanyo lwesitshizi setyuwa bukhulu okanye bulingana neeyure ezingama-96. |
| Electrogalvanizing | Imeko yangaphakathi, enobume obuncinci | ISO 4042 (yamazwe ngamazwe), ASTM B633 (USA) | Ubukhulu be-Zinc plating Inkulu kuno okanye ilingana ne-10μm, unyango lwe-passivation (bhlowu{1}}mhlophe/nombala), uvavanyo lwesitshizi setyuwa Esikhulu okanye silingana neeyure ezingama-48. |
| Ukunyamezela | Ukutya, amayeza okanye{0}}ucoceko oluphezulu | I-ASTM A967 (USA), EN ISO 3651-2 (EU) | Ukunyangwa kwePassivation kususa ukungcola komhlaba, kungashiyi amabala e-oyile okanye iminwe yeminwe; uvavanyo lwesitshizi setyuwa Inkulu kune okanye ilingana neeyure ezingama-72. |
Kwibhodi ejingayo yohlobo lwe-Clevis olusetyenziswa kurhwebo lwangaphandle, uzinzo lwesakhiwo lubalulekile kuba kufuneka lusetyenziswe ixesha elide kumaziko ombane, kwaye ubume bumisela ubomi benkonzo. Ukuphucula ixabiso lemveliso{1}}ukusebenza, ezi mfuno uzinzo zilandelayo ziyasebenza:
I-Flatness: Ngaphantsi okanye ilingana ne-0.3mm / m, enokuthintela ukungahambi kakuhle kokufakela kunye noxinzelelo olungalinganiyo ngenxa yokuguqulwa ngexesha lokusetyenziswa;
Ukuchaneka kwendawo yomngxuma: Ukutenxa kwisithuba somngxuma phakathi komngxuma wokunqunyanyiswa kunye nomngxuma wokudibanisa ungaphantsi okanye ulingana no-0.2mm, kwaye ukunyamezela kwedayamitha yomngxuma yi-H13. Ngexesha lokusetyenziswa, inokudityaniswa ngokuchanekileyo kunye nezikhonkwane kunye neebholithi, kwaye akusayi kubakho kushukuma nasemva kokusetyenziswa kwexesha elide{2}};
Ukuthembeka kwe-Weld: Amandla okuqina e-weld makhulu okanye alingana ne-85% yamandla okuqina kwesiseko sesinyithi, kwaye akukho ziphene ezifana ne-porosity, ukufakwa kwe-slag, okanye ukungena okungaphelelanga. Emva kwe-welding, uvavanyo lwe-penetrant (PT) okanye uvavanyo lwe-ultrasonic (UT) lufunekayo ukuze kuqinisekiswe ukuba i-weld ayinayo i-cracks yangaphakathi.
