Inqubo yokuqandisa kanye nenqubo yokushisa ephezulu isetshenziswa emikhakheni eminingi. Isibonelo, inqubo yokwelapha ukushisa iyinqubo eshisisa izinto zensimbi noma imikhiqizo yazo ezingeni lokushisa elidingekayo, ipholise ngesivinini esikhethiwe nendlela, iguqule isakhiwo sayo sangaphakathi, futhi ithole ukusebenza okudingekayo. Lolu hlobo lwenqubo lusetshenziswa emikhakheni eminingi yokucubungula imikhiqizo yezimboni, kodwa induku yepiston iphathwa kanjani ukushisa? Yiziphi izindlela zayo zokwelapha ukushisa? I-Yantai Shunfa Component Pneumatic Co., Ltd. iphendula kanje.
Inhloso yokucisha kanye nokwelashwa kokuthulisa iwukuqinisekisa ukuthi induku yepiston inezakhiwo ezibanzi ezihambisana namandla, ubulukhuni, ipulasitiki, kanye nokuqina kahle. Isakhiwo sangaphakathi siyi-sorbite efanayo nenhle, elungiselelwa ukucisha indawo elandelayo. I-cylinder piston rod ende inobude obungu-3800-4200 kanye nobubanzi buka-Φ 90- Φ 110mm, ngakho-ke okokusebenza kwayo kokushisisa kwamukela isithando somlilo sokumelana nohlobo lwe-150KW noma isithando somlilo esiqhubekayo esingama-600KW, esinokushisa okulawulwa ezindaweni ezimbili: phezulu. futhi ngaphansi. Imingcele yenqubo yokwelapha ukushisa: Amashubhu amane amisiwe esithandweni esisodwa esithandweni somthombo, esinokushisa okucishayo okungu-830 ± 10 ℃. Ngemva kokubamba imizuzu engu-160, amashubhu acinywa izikhathi ezimbili, namashubhu amabili acinywa isikhathi ngasinye. Amanzi okupholisa ajikelezayo asetshenziselwa ukupholisa amashubhu, azungeza phezulu naphansi ngesikhathi sokucisha ukuze kuqinisekiswe ukupholisa okufanayo ngezinga elikhulu. Uma epholile aze afike ku-100 ℃ (izinduku zikhipha isitimu kodwa zingaphumi), amanzi ageleza esithandweni somlilo sohlobo lomthombo ukuze afudumale.
Khona-ke amashubhu amane ashiswa ku-550 ± 10 ℃ ngesikhathi, abanjwe imizuzu engu-190, futhi ashiswe ngaphambi kokupholisa kwamanzi. Ngemuva kwenqubo engenhla yokucisha kanye nokwelashwa kokushisa, ukusebenza akuzinzile, futhi ubulukhuni buyashintshashintsha phakathi kuka-210-255HBS. Kuphinde kube nomehluko obalulekile wokuqina phakathi kwezingxenye ezingenhla, eziphakathi, neziphansi ze-piston rod efanayo. Futhi ngezinye izikhathi kuba khona ukushisa okukodwa ngobulukhuni obungafanelekile noma amandla aphansi adinga ukwelashwa kokulungisa. Ukucisha i-deformation kukhulu uma kuqhathaniswa, okwandisa ubunzima bokuqondisa okulandelayo kanye nokucutshungulwa kwemishini. Ngenxa yokuqina okungalungile kwensimbi engu-45, isakhiwo sangaphakathi esibhekwa yi-metallography akuyona i-sorbite eyodwa futhi efanayo, kodwa kunalokho inani elikhulu le-sorbite yamahhala likhona phakathi nendawo yalo, futhi ezinye izingxenye zinenethiwekhi ye-sorbite ne-Widmann isakhiwo.
Ukuze sixazulule izinkinga ezingenhla, sisebenzisa isithando somlilo esimisiwe esimisiwe sokucisha nokushisa, esinamashubhu angu-2 afakiwe ngeshubhu ngayinye. Ngemva kokushisa nokufakwa kwe-insulation, isithando somlilo sicima ngokuzenzakalelayo, futhi kukhiqizwa ishubhu elilodwa ngesigqi ngasinye ukuze kuqinisekiswe ukushisa okufanayo. Uma kucatshangelwa ukuthi izinga lokushisa le-Ac3 lensimbi engu-45 lingu-770-780 ℃, ukuze kucwengwe okusanhlamvu futhi kuncishiswe ukuwohloka ngangokunokwenzeka, sisebenzisa inqubo yokucisha engu-790 ± 10 ℃ yokucwenga okusanhlamvu kwe-austenite, futhi sithole ama-noodle amahle futhi afanayo. i-martensite ngemva kokucisha, ukuze kuthuthukiswe amandla nokuqina kwenduku ye-piston. Ukuze kuqhutshekwe nokunciphisa ukuwohloka nokuthuthukisa ukufana kokupholisa kwesisombululo sokucisha, sengeze izithasiselo zokucisha ezingu-5% -10% emanzini kampompi. Ngesikhathi sokucisha, siphinde sasebenzisa iphampu yamanzi ejikelezayo ukuze siphoqelele isisombululo sokupholisa ukuze sijikeleze ukuze kuphole. I-Tempering isashisiswe ku-550 ± 10 ℃, ngesigqi sokucisha esifanayo nangaphambili. Ngemva kokushisa, ipholiswa ngamanzi ukugwema ukuvela kohlobo lwesibili lwe-teering brittleness. Ngemuva kokuthuthukiswa kwenqubo engenhla, isakhiwo sangaphakathi sifana ne-sorbite epholile, ngokususwa kwe-ferrite enkulu noma e-reticular kanye nesakhiwo se-Widmann, okuholela ekuqineni okufanayo nokuzinzile namandla.
