Steel ibha eqeda futhi tempering umugqa ukukhiqizwa

A. Izinzuzo ze insimbi yokuqeda ibha kanye nomugqa wokukhiqiza we-tempering

1. The insimbi yokuqeda ibha kanye nomugqa wokukhiqiza we-tempering inganciphisa kakhulu umugqa wensimbi wokucima nokucisha ukukhiqiza nokwenza ngcono izimo zokusebenza.

2.Umugqa wensimbi wokucima nokucisha ukukhiqizwa kwensimbi ungathuthukisa izinga lenhlangano yensimbi yokucima uketshezi nokukhiqizwa kwethayela futhi ithuthukise ikhwalithi yomkhiqizo.

3. Imishini yokufudumeza engenayo yomugqa wensimbi wokucisha nokucisha ulingo igcina izinto ngaphezu kwesithando somlilo, futhi ngasikhathi sinye ithuthukisa impilo yensimbi yebha yensimbi ngemuva kokucima nokushisa.

4. Ulayini wensimbi wokucisha nokucisha ithenda awukhiqizi intuthu nentuthu ngenxa yokushisa kwe-induction, okuhlanza indawo yokusebenza yendawo yokusebenzela.

5. Isikhathi sokushisa se-induction sokucisha ibha yensimbi kanye nentambo yokukhiqiza ukufuthelana sifushane futhi ukusebenza kahle kuphezulu.

B. Uhlolojikelele lwensimbi yokukhiqiza ibha yokuqeda nokushisa

1.Umugqa wensimbi wokucima nokucisha ukukhiqizwa kwe-tempering ulawulwa amandla kagesi aphakathi nendawo, futhi ukulungiswa kuvulwe ngokuphelele ukufeza amandla aphezulu.

2. Ukudlulisa itafula le-roller: I-eksisi yetafula le-roller kanye ne-eksisi yensimbi yokusebenza yakha i-engeli engu-18 ~ 21 °, kuthi okokusebenza kuqhubekele phambili ngejubane eliqhubekayo ngenkathi i-autotransmitting, ukuze ukufudumeza kufane kakhulu. Itafula le-roller phakathi kwesithando somlilo lenziwe ngensimbi engagqwali engama-304 non-selehlile ngamanzi. Ezinye izingxenye zetafula le-roller zenziwe ngensimbi engu-45 nobuso obukhuni.

3. Ukuqoqwa kwetafula le-roller kwensimbi yokuqeda ibha yensimbi kanye nemishini yokushisa: iqembu lokuphakela, iqembu lenzwa neqembu elikhiphayo lilawulwa yisiguquli semvamisa esihlukile, esizuzisa ijubane elifanayo lebha ngesikhathi senqubo eya phambili.

4. Uhlelo lokushisa lwe-loop-closed-loop: Lisebenzisa i-American Leitai infrared thermometer ehlangene ne-German Siemens S7 ukwakha uhlelo lokulawula ukuvala, olungakwazi ukulawula ngokunembile izinga lokushisa nokushisa ngokulinganayo.

5.Izinsimbi zokucisha nokucisha i-steel bar ilawulwa yikhompyutha yezimboni, ekhombisa isimo semingcele yokusebenza ngaleso sikhathi ngesikhathi sangempela, nemisebenzi efana nememori yepharamitha yokusebenza, ukugcinwa, ukuphrinta, ukubonisa amaphutha, nokwenza kusebenze isignali ephuthumayo .

6. Umsebenzi wokusebenza ngemuva kokucima nokushisa entanjeni yensimbi nokukhiqiza ithubhu ayinayo imifantu futhi akukho ukusonteka, kanti izinga lemikhiqizo efanelekile lifinyelela kuma-99%.

7. Ubuchwepheshe bokulawula obufanayo nobuchungechunge be-resonance bokucisha i-steel bar nokucisha ugesi wokukhiqiza amandla, ukuthinta okugcwele kokusebenza kwedijithali kokungeniswa kokushisa nokuqeda imishini yokwelashwa kokushisa, iyimishini yezobuchwepheshe bokushisa bokungeniswa emhlabeni jikelele.

C.Ukufundwa okwenziwe ngocingo lwensimbi lokucisha nokucisha umugqa wokushisa:

1.Umugqa wensimbi wokucisha nokucisha ukukhiqizwa kwe-tempering usetshenziselwa ukucisha nokushisa okunamandla kwezinduku ze-hydraulic kanye nezinduku zokudonsa.

2. Amapharamitha wensimbi acinyiwe futhi asebenza ngomlilo

1) impahla yomkhiqizo: 45 # steel, 40Cr, 42CrMo

2) Imodeli yomkhiqizo (mm): Ububanzi: 60≤D≤150 (induku yensimbi eqinile) Ubude: 2200mm ～ 6000mm;

3) Ibha yensimbi iyafudunyezwa ekushiseni okucimayo ngemvamisa ephakathi futhi bese selehlile ukwelashwa okucimayo, futhi ukwelashwa kwe-tempering kwenziwa ku-inthanethi.

Icima ukushisa okushisa: 950 ± 10 ℃; Ukushisa okushisa okushisa: 650 ± 10 ℃;

4) Amandla wokufaka: 380V ± 10%

5) Lokukhipha mfuneko: 2T / H (kuncike 100mm steel bar)

Izidingo zobuchwepheshe zensimbi yokukhiqiza ibha yokuqeda nokushisa

1) Ubulukhuni bomhlaba jikelele bomphetho wonke bungu-22-27 degrees HRC, ubunzima obuncane abukwazi ukuba ngaphansi kwama-22 degrees, nobulukhuni obufanele ngama-24-26 degrees;

2) Ubulukhuni bomphimbo ofanayo kufanele bube ngokufana, nobulukhuni beqoqwana elifanayo kufanele futhi bube ngokufana, futhi ukufana komphimbo kufanele kube ngaphakathi kwama-degree ama-2-4.

3) Inhlangano kufanele ifane, futhi izakhiwo zomshini kufanele zihlangabezane nezidingo:

a. Amandla esivuno makhulu kuno-50kgf / mm²

b. Amandla eqine makhulu kuno-70kgf / mm²

c. Ukunwebeka kukhulu kuno-17%

4) Indawo ephansi kakhulu enkabeni yombuthano ngeke ibe ngaphansi kune-HRC18, indawo ephansi kakhulu engu-1 / 2R ngeke ibe ngaphansi kune-HRC20 degrees, futhi iphuzu eliphansi kakhulu le-1 / 4R ngeke libe ngaphansi kune-HRC22 degrees.

E. Incazelo yenqubo yokugeleza kwensimbi yokuqeda ibha kanye nolayini wokukhiqiza we-tempering

Okokuqala, ngesandla beka izinduku zensimbi ezidinga ukufudunyezwa emgqeni owodwa nongqimba owodwa kuthebhu yesitoreji sokudla, bese okokusebenza kuthunyelwa kancane ku-rack rack ngomshini wokulayisha, bese leyo nto ifakwa ku ukondla i-roller ethambekele ngesilinda somoya. I-roller oblique ishayela impahla yebha phambili futhi ithumela okokusebenza kwi-quenching heat inductor. Ngemuva kwalokho i-workpiece iyashiswa ngengxenye yokushisa okucimayo, bese kuthi ukushisa okucimayo kuhlukaniswe kube ukucisha ukushisa okushisa nokuqeda ukushisa kokugcina ukushisa. Engxenyeni yokucima ukucisha, kusetshenziswa ugesi wamaphakathi wamandla angama-600Kw ukushisa indawo yokusebenza, bese kusetshenziswa amasethi amabili wamandla kagesi angama-200Kw aphakathi nendawo okulondolozwa nokushisa.

Ngemuva kokuthi ukufudumeza sekuqediwe, indawo yokusebenza iqhutshwa yiroli ethambekele ekudluliseni indandatho yokufafaza amanzi yokuqeda. Ngemuva kokuthi ukucisha kuqediwe, ingena ekushiseni kwe-tempering yokushisa okushisa. Ukushisa kwe-Tempering kubuye kwehlukaniswe kwaba izingxenye ezimbili: ukufudumeza ukufudumala nokushisa ukushisa. Ingxenye yokushisa yamukela ukuphakelwa kwamandla kagesi angama-300Kw Lesisemkhatsini, kanti ingxenye yokulondolozwa kokushisa isebenzisa amasethi amabili we-100KW.

Ibha yensimbi kanye nensimbi yokukhiqiza ibha yokuqeda nokushisa kukhiqiza izixazululo ezikhetha ukusebenza okuphezulu nezingabizi kakhulu ngokuya ngezidingo zenqubo ehlongozwe yikhasimende. Ulayini ophelele wokukhiqiza ufaka phakathi imishini yokushisa yamaphakathi, umshini wokuhambisa imishini, idivaysi yokukala ukushisa kwe-infrared, isistimu yokupholisa amanzi evaliwe, nebhokisi lokulawula eliphakathi njll.
