Isetyenziswa rhoqo kwi-power-saw kwikona ezibukhali kunye namabhore.Oku kunamandla ngaphezu kwezixhobo ezinamava ze-high-carbon steel eziye zasetyenziswa ngokuqhelekileyo ukususela ngo-1940 njengoko zikwazi ukuphatha amaqondo okushisa aphezulu ngaphandle kokuchaphazela amandla abo (ubunzima).Le propati inceda i-HSS ukuba inqumle ngokukhawuleza kune-carbon steel high, ngoko ke igama elithi High Speed ​​Steel.Kubushushu begumbi, apho, ubukhulu becala, unyango lobushushu olucetyisiweyo, uphononongo lwe-HSS, ubukhulu becala, lubonisa ubulukhuni obuphezulu (ngaphezulu kobunzima be-Rockwell 60) kunye nenkcaso ekhutshiweyo (ngokubanzi idityaniswe kwi-tungsten kunye nomxholo we-vanadium osetyenziswa rhoqo HSS) umahluko kunye nekhabhoni eqhelekileyo kunye nesixhobo silungiselela.

Usetyenziso

Olona setyenziso luphambili lwesantya esiphakamileyo silungiselela ukuhlala ekudityanisweni kwezixhobo zokusika ezahlukeneyo: iidrili, iitephu, izisiki zokucoca, iibhithi zesixhobo, ii-hobbling (igiya) izisiki, iikona ezibukhali, iplani, kunye nemiphetho edibeneyo, iibhithi zokutshintsha, njalo njalo. ., nangona ukusetyenziswa kwe punch kunye nokukhaba ibhakethi liyanda.

Amalungiselelo akhawulezayo afumene i-niche kwizixhobo zesandla ezilungileyo apho ubomi babo obude obuphezulu kubunzima obuphezulu zidityaniswe nenkcaso ephezulu ekhutshiweyo ibenze bafaneleka kwizicelo ezinesantya esisezantsi ezifuna indawo ebukhali, efana nezigodo, iitshi, imiphezulu yenqwelomoya yezandla, kunye neeblades zasekhitshini. eDamasko iimela zokusonta.

Izixhobo zentsimbi ezinesantya esiphezulu zezona zaziwa kakhulu ngokusetyenziswa ekwenzeni amaplanga, ekubeni inqanaba lemveliso yomsebenzi ngaphaya komphetho likhawuleza ngokukhawuleza kwizixhobo eziphathwa ngesandla, ngoko ke i-HSS inomphetho omde kakhulu kunezixhobo eziqhelekileyo zentsimbi yekhabhoni.

Iintlobo

Ukwenziwa ngokukhawuleza zii-amalgam ezifumana iipropati zazo kwinani leentsimbi ezixutywayo ezifakwe kwi-carbon steel, ngokuqhelekileyo njenge-tungsten kunye ne-molybdenum, okanye ukusuka kwindibaniselwano yezi zibini, ngamanye amaxesha kunye neekhompawundi ezahlukeneyo.Banesikhundla kwi-multi-part composite structure Fe - C - X apho i-X ibhekisela kwi-chromium, i-tungsten, i-molybdenum, i-vanadium okanye i-cobalt.Uluhlu lwe-X lusetyenziswa kakhulu kwi-7 yeepesenti, kunye ne-carbon engaphezu kwe-0.60 yeepesenti.

Iiklasi zohlobo lweTungsten (umz. T1, T15) kwinkqubo yokubala iinombolo ezidityanisiweyo (UNS) zinikwe amanani kwisakhiwo se-T120xx, ngelixa i-molybdenum (umz. M2, M48) kunye ne-T113xx ziphakathi kweendlela zendlela.Amaxabiso e-ASTM abonisa iifom ze-7 ze-tungsten kunye ne-17 iifom ze-molybdenum.

Ukwandiswa malunga ne-10% ye-tungsten kunye ne-molybdenum ngokupheleleyo kwandisa ngokuvelisa ubulukhuni kunye nokuqina kwe-Speed ​​​​Speed ​​​​Speed ​​​​ilungiselela kwaye igcine ezo zakhiwo kumaqondo okushisa aphezulu adalwe xa usika isinyithi.

Inokuhlala njani nzima?

Kwinqanaba xa ucinga ngesixhobo sokusika i-HSS, qwalasela ubushushu.Ukufudumala okuncinci okwenzayo (kwisixhobo), isixhobo esikhutshwe ngakumbi siya kuhlala.Kwinqanaba xa ubushushu buphatha i-HSS uyisa kubushushu obuthile (ngoku obubizwa ngokuba bubushushu obuphezulu) kangangexesha elichaziweyo.Oku kunika i-HSS ubulukhuni bayo obucacileyo, kodwa ibuthathaka kakhulu.Okulandelayo ithathe iqondo lobushushu ukuze “icaphuke okanye iwutsale”.Oku kufezwa ngokubanzi ngaphezu kwesihlandlo esinye.Oku kuthwala ubunzima apho ufuna khona kwaye unika ukuqina kwe-HSS (zombini ubunzima kunye namandla zilawulwa yi-composite kwizinto eziphathekayo).Ubushushu bobushushu akufunekanga bugqithwe ekusebenziseni okanye ekuboleni isixhobo okanye siya kuqina (relax).Oku kuya kwahluka ukusuka kwisibini sokugxila (Rc) ukuya kwicala elisezantsi elipheleleyo.Le yingcaciso esisiseko kakhulu yokufudumala kunomvuzo we-HSS.
