Ngokuya ngobulukhuni babo obucacile, izinsimbi zamathuluzi zisetshenziselwa ukwenza amathuluzi okusika afaka imimese nezivivinya, kanye nokwakha izidumbu ezithinta isitembu futhi zenze insimbi yensimbi. Ukukhetha ibanga lensimbi elihamba phambili kuzoncika ezintweni eziningi, kufaka phakathi:

1. Amabanga nokusetshenziswa kwensimbi yensimbi

2. Ithuluzi lensimbi lehluleka kanjani

3. Izindleko zensimbi yensimbi

Amabanga nezicelo ka Ithuluzi lensimbi

Ngokususelwa ekwakhiweni kwayo, ekwakheni noma kweqa ibanga lokushisa, nohlobo lokuqina ababa nakho, amathuluzi wensimbi ayatholakala emabangeni ahlukahlukene. Amabanga wenhloso ejwayelekile yensimbi yensimbi yi-O1, A2, ne-D2. Lezi zinsimbi ezisezingeni eliphakeme zibhekwa “njengezinsimbi ezisebenza ngamakhaza,” ezingabamba umkhawulo wazo emazingeni okushisa aze afike cishe ku-400 ° C. Zibonisa ubulukhuni obuhle, ukumelana nemihuzuko, kanye nokumelana ne-deformation. 

I-O1 iyinsimbi eqinisa uwoyela ngobulukhuni obuphakeme nokusebenza kahle kwemishini. Leli banga lensimbi yensimbi lisetshenziselwa kakhulu izinto ezinjengamathuluzi okusika nama-drill, kanye nemimese nezimfoloko.

I-A2 iyinsimbi eqinisa umoya equkethe inani eliphakathi lokuhlanganisa izinto (i-chromium). Ine-machinability enhle kanye nebhalansi yokuqina kokuqina nobulukhuni. I-A2 yizinhlobonhlobo ezisetshenziswa kakhulu zensimbi eyenza umoya uqine futhi ijwayele ukusetshenziselwa ukungabi nalutho nokwakha izibhakela, ukusika izidumbu nokufa komjovo.

Insimbi ye-D2 ingaba lukhuni kawoyela noma iqiniswe umoya, futhi iqukethe iphesenti eliphakeme lekhabhoni ne-chromium kune-O1 ne-A2 steel. It has a bafake ukumelana okusezingeni eliphezulu, ubulukhuni okuhle futhi ukuhlanekezela ongaphakeme emva kokushisa ukwelashwa. Amazinga aphezulu wekhabhoni ne-chromium ku-D2 steel enza kube ukukhetha okuhle kuzinhlelo zokusebenza ezidinga impilo yethuluzi elide. 

Amanye amamaki wensimbi yamathuluzi aqukethe amaphesenti aphezulu ezinhlobo ezahlukahlukene zama-alloys, njenge-high speed steel M2, engakhethwa ngokukhiqizwa kwevolumu ephezulu. Izinhlobonhlobo zezinsimbi ezishisayo ezisebenzayo zingagcina unqenqemeni lokusika olubukhali emazingeni okushisa aphakeme kakhulu afinyelela ku-1000 ° C.

Ithuluzi Lensimbi Liyahluleka Kanjani?

Ngaphambi kokukhetha ibanga lensimbi yethuluzi, kubalulekile ukuthi ubheke ukuthi yiluphi uhlobo lokwehluleka kwamathuluzi okungenzeka lube lolu hlelo ngokuhlola amathuluzi ahlulekile. Isibonelo, amanye amathuluzi ehluleka ngenxa yokugqoka okweqile, lapho okusikwayo kugcina phansi ithuluzi, noma ngabe lolu hlobo lokwehluleka luyephuza ukwenzeka futhi lungalindelwa. Ithuluzi eligugile ekuhlulekeni lidinga insimbi yamathuluzi enokumelana okukhulu kokugqoka.

Ezinye izinhlobo zokwehluleka ziyinhlekelele enkulu, njengokuqhekeka, ukuqhekeka, noma ukusonteka kwepulasitiki. Kwithuluzi eliphukile noma eliqhekekile, ukuqina noma ukumelana nomthelela wensimbi yensimbi kufanele kukhuliswe (qaphela ukuthi ukumelana nomthelela kuncishiswe ngamanothi, ama-undercuts, nama-radii abukhali, ajwayelekile kumathuluzi futhi afayo). Okwethuluzi elikhubazekile ngaphansi kwengcindezi, ubulukhuni kufanele bunyuswe. 

Khumbula, kepha, ukuthi izakhiwo zensimbi zensimbi azihlobene ngqo, ngakho-ke ngokwesibonelo, kungadingeka ukuthi udele ukuqina kokuqina kokugqoka okuphezulu. Kungakho kubaluleke kangaka ukuqonda izakhiwo zamathuluzi wezinsimbi ahlukene, kanye nezinye izinto ezifana neJiyomethri yesikhunta, okokusebenza okusetshenziswayo, nomlando wokwenza ithuluzi uqobo.

I- Izindleko Of Ithuluzi Steel

Into yokugcina okufanele uyicabangele lapho ukhetha ibanga lensimbi yensimbi izindleko. Ukusika amakhona ekukhetheni kwempahla kungahle kungaholeli kuzindleko eziphansi zokukhiqiza uma ithuluzi lizibonakalisa liphansi futhi lihluleka ngaphambi kwesikhathi. Ibhalansi kufanele itholakale phakathi kwekhwalithi enhle nentengo enhle.

Insimbi Yomlando waseShanghai ibilokhu igxile ekuthengisweni kwethuluzi nensimbi yesikhunta kusukela ngo-2003. Imikhiqizo ifaka phakathi: insimbi yomsebenzi ebandayo yensimbi, insimbi yomsebenzi eshisayo insimbi, isivinini sensimbi, isikhunta sensimbi, insimbi engagqwali, i-planer imimese, izikhala zethuluzi.
