Ukuhlaziywa okujulile kwesikhathi sokwelashwa kwe-roller chain ngemuva kokushisa

Isingeniso
Enqubweni yokukhiqiza amaketanga e-roller, ukwelashwa ngemva kokushisa kuyisixhumanisi esibalulekile. Kuthinta ngqo ukusebenza, impilo kanye nokuthembeka kwamaketanga e-roller. Kubathengi bamazwe ngamazwe abathengisa ngobuningi, ukuqonda isikhathi kanye nemingcele yenqubo ehlobene yokwelashwa ngemva kokushisa kwamaketanga e-roller kuzobasiza ukuthi bahlole kangcono ikhwalithi yomkhiqizo futhi bakhethe abaphakeli abafanelekile. Lesi sihloko sizohlola izixhumanisi ezahlukene kanye nesikhathi esidingekayo sokwelashwa ngemva kokushisa kwamaketanga e-roller, futhi sizihlaziye ngokujulile kanye nezimo zangempela.

Ukubuka konke kokwelashwa kwe-roller chain ngemuva kokushisa
Ukwelashwa kwe-roller chain ngemva kokushisa kuhlanganisa kakhulu izinyathelo ezimbili eziyinhloko: ukucima nokushisa. Inhloso yayo ukuthuthukisa izakhiwo zemishini ze-roller chain, njengokuqina, ukuqina nokumelana nokuguguleka, ngokushisa okushisa okuphezulu kanye nokupholisa okusheshayo (ukucima) kanye nokushisa okuphansi okulandelayo (ukushisa). Isikhathi kanye nemingcele yokushisa yokwelashwa kokushisa kuzohluka kuye ngezinto zokwakha, usayizi kanye nezidingo zokusetshenziswa kokugcina kwe-roller chain.

Izinyathelo eziyinhloko kanye nesikhathi sokwelashwa kwe-roller chain ngemuva kokushisa
1. Ukucima
Ukucima kuyisinyathelo sokuqala sokwelashwa nge-roller chain ngemva kokushisa. Inhloso yaso ukushintsha isakhiwo sangaphakathi se-roller chain ngokupholisa okusheshayo, ngaleyo ndlela kuthuthukiswe ubulukhuni namandla. Isikhathi sokucima ngokuvamile sifushane, kodwa izinga lokushisa kanye nezinga lokupholisa kudingeka kulawulwe ngokunembile.
Isikhathi sokushisa: Kuye ngezinto ezahlukene nezidingo zenqubo, isikhathi sokushisa ngokuvamile siphakathi kwemizuzu emi-2 nengu-3. Isibonelo, uma usebenzisa insimbi ephansi ye-alloy ephansi ukuze ukhiqize amaketanga e-roller, izinga lokushisa lokushisa lingu-870-890℃ kanti isikhathi sokushisa singu-2-3 imizuzu.
Isikhathi sokupholisa: Isikhathi sokupholisa sokucisha sifushane kakhulu futhi sivame ukuqedwa ngemizuzu embalwa. Ukulawulwa kwezinga lokupholisa kubalulekile ngoba kuthinta ngqo ubulukhuni kanye nokucindezeleka kwangaphakathi kweketanga le-roller.
2. Ukulinganisela
Ukushisa kuyisinyathelo sesibili sokwelashwa kwamaketanga okugoqa ngemva kokushisa. Inhloso yaso ukunciphisa ukucindezeleka kwangaphakathi ngemva kokucima ngokushisa okuphansi ngenkathi kugcinwa ubulukhuni nokuqina okuthile. Isikhathi sokushisa ngokuvamile siba side kunesikhathi sokucima.
Ukushisa Kwangaphambi Kokushisa: Izinga lokushisa lokushisa kwangaphambi kokushisa livame ukuba cishe ngu-130℃, kanti isikhathi sokubamba singamahora angaba ngu-2.5 kuya ku-3.5. Lesi sinyathelo sisiza ekuqaleni ukuzinzisa isakhiwo sangaphakathi se-roller chain.
Ukushisa kwesibili: Izinga lokushisa lokushisa kwesibili livame ukuba cishe ku-250℃, kanti isikhathi sokubamba singamahora ama-4 kuya kwangu-5. Ukushisa kwesibili kungathuthukisa kakhulu izakhiwo zemishini ze-roller chain futhi kugcine kuzinzile ekusetshenzisweni kwesikhathi eside.

Izici ezithinta isikhathi sokwelashwa ngemva kokushisa kwamaketanga ajikelezayo

1. Ukwakheka kwezinto

Ukwakheka kwezinto zochungechunge lwe-roller kunomthelela omkhulu esikhathini salo sokwelashwa kokushisa kanye nemingcele yenqubo. Isibonelo, izinga lokushisa lokucima kanye nesikhathi sensimbi ephansi ye-carbon-alloy kuhlukile kunensimbi evamile yekhabhoni. Ukwakheka kwezinto ezahlukene kudinga ukulungiswa kokushisa kokushisa, isikhathi sokubamba kanye nesilinganiso sokupholisa ukuqinisekisa izakhiwo zemishini ezifanele.

2. Usayizi weketanga le-roller

Ubukhulu beketanga lama-roller buthinta nesikhathi sokwelashwa ngemva kokushisa. Amaketanga ama-roller amakhulu adinga isikhathi eside sokushisa nokupholisa ukuqinisekisa ukusatshalaliswa kokushisa okufanayo kanye nezinguquko ezifanayo esakhiweni sangaphakathi.

3. Izidingo zokunemba kwenqubo

Izinhlelo zokusebenza ezahlukene zinezidingo ezahlukene zokunemba nokusebenza kwamaketanga okugoqa. Isibonelo, amaketanga okugoqa asebenza kahle kakhulu futhi ahlala isikhathi eside adinga izinqubo zokwelashwa kokushisa eziqinile kanye nezikhathi zokucubungula ezinde. Inqubo yokwelashwa kokushisa yale ketanga lokugoqa ifaka izinyathelo eziningi ezifana nokushisa kusengaphambili, ukugaya i-carburizing kanye nokucima, ukupholisa, ukuhlanza, ukufudumala kwangaphambili kanye nokushisa kwesibili, kanye nesikhathi kanye nemingcele yesinyathelo ngasinye kudinga ukulawulwa ngokunembile.

Ukuhlaziywa kwangempela kwecala lokwelashwa kwe-roller chain ngemuva kokushisa
Icala 1: Uchungechunge lwe-roller yensimbi olune-carbon ephansi
Ngokusho kwelungelo lobunikazi, uma usebenzisa insimbi engaphansi kwe-carbon ephansi ukukhiqiza amaketanga e-roller, inqubo yokwelapha ngemva kokushisa imi kanje:
Ukucima: izinga lokushisa lokushisa 870-890℃, isikhathi sokushisa imizuzu engu-2-3, kulandelwe ukucima i-press oil spray.
Ukushisa: izinga lokushisa lokushisa 200-350℃, isikhathi sokubamba silungiswe ngokwezidingo ezithile.
Le nqubo ingathuthukisa kakhulu amandla kanye nokumelana nokuguguleka kweketanga le-roller, ngenkathi inciphisa isisindo seketanga.
Icala 2: Iketanga lama-roller elihlala isikhathi eside elinokunemba okuphezulu
Ngokusho kwelungelo lobunikazi, inqubo yokwelapha ngemva kokushisa yeketanga lama-roller elihlala isikhathi eside elinokunemba okuphezulu ihlanganisa izinyathelo ezilandelayo:
Ukushisa: shisa i-roller ku-450-500℃, gcina ifudumele amahora angu-1.5-2.5.
Ukucima i-carburizing: shisa kufike ku-900-1000℃, dlulisa i-acetone ne-methanol, lawula amandla e-carbon ku-1.10±0.05%, gcina kufudumele amahora angu-3-4 ngaphambi kokucima.
Ukupholisa: Izinga lokushisa lokupholisa lilawulwa ku--10℃ kuya ku--15℃, isikhathi singamaminithi ayi-10-20.
Ukushisa kwangaphambili: izinga lokushisa 130±5℃, isikhathi amahora angu-2.5-3.5.
Ukushisa kwesibili: izinga lokushisa 250±5℃, isikhathi samahora angu-4-5.
Le nqubo ingathuthukisa kakhulu ukumelana nokuguguleka, ukumelana nokugqwala kanye nokuqina komthelela wamaketanga ajikelezayo.

Isiphetho
Imingcele yesikhathi kanye nenqubo yokwelashwa kwe-roller chain ngemuva kokushisa yizinto ezibalulekile ukuqinisekisa ikhwalithi yomkhiqizo. Ngokulawula ngokunembile isikhathi sokushisa, izinga lokushisa kanye nezinga lokupholisa, izakhiwo zemishini kanye nokuphila kwesevisi ye-roller chain kungathuthukiswa kakhulu. Kubathengi bamazwe ngamazwe abathengisa ngobuningi, ukuqonda lezi zinhlaka zenqubo kuzobasiza ukuthi bahlole kangcono izinga lobuchwepheshe lomhlinzeki kanye nekhwalithi yomkhiqizo. Esikhathini esizayo, ngentuthuko eqhubekayo yesayensi yezinto zokwakha kanye nobuchwepheshe bokwelashwa kokushisa, inqubo yokwelashwa kwe-roller chain ngemuva kokushisa izothuthukiswa ngokwengeziwe ukuze ihlangabezane nezidingo zokusebenza eziphakeme.
