Iindlela ezi-7 zokungaphumeleli zeTungsten Carbide Buttons

Njengomenzi wamaqhosha e-tungsten carbide, sifumene abathengi abaninzi abanengxaki yemibuzo malunga nokungaphumeleli kwe-tungsten carbide. Le mibuzo ingabaukunxitywa kwe-abrasive, ukudinwa kwe-thermal, i-spalling, iintanda zangaphakathi, ukwaphuka kweendawo ezingavezwanga zeqhosha le-carbide, i-shear fracture, kunye nokuqhekeka komhlaba.. Ukusombulula ezi ngxaki, kufuneka sifumanise ukuba zeziphi ezi ndlela zokungaphumeleli, kwaye sijonge indawo apho amaqhosha e-carbide wonakaliswe kakhulu kwaye anxitywa kaninzi, amaqhosha e-carbide aqhekeka umphezulu. Kweli nqaku, siza kuthetha ngezi 7 iindlela zokungaphumeleli kunye neengcebiso zokuzisombulula.

1. Ukunxiba kwe-abrasive

Yintoni ukunxiba kwe-abrasive?

Ukunxitywa kwe-abrasive kwenzeka ngexesha longquzulwano kunye nokungqubana phakathi kwamaqhosha e-tungsten carbide kunye namatye. Le yimowudi yokungaphumeleli eqhelekileyo nengenakuthintelwa, ekwayindlela yokusilela kokugqibela kwamasuntswana e-drill. Ngokuqhelekileyo, ukugqoka amaqhosha aphakathi kunye namaqhosha okulinganisa ahluke. Amaqhosha e-carbide, asondele kumda, okanye anesantya esiphezulu somgca ngexesha lomsebenzi, aya kuba neengxabano ezinkulu kunye nelitye, kwaye ukunxiba kunokuba nzima ngakumbi.

Iingcebiso

Xa kukho ukunxitywa kwe-abrasive kuphela, sinokuphucula ngokufanelekileyo ukuxhatshazwa kwamaqhosha e-tungsten carbide. Sinokunciphisa inani le-cobalt okanye siphucule i-WC ukuze sifezekise injongo. Yintoni esifanele siyiqaphele kukuba ukunyanzeliswa kokugqoka kwamaqhosha okulinganisa kufuneka kube phezulu kunokuba amaqhosha aphakathi. Ukunyuka kokuqina kunokuba nemveliso ukuba kukho ukungaphumeleli okunokwenzeka.

2. Ukudinwa kwe-thermal

Yintoni ukudinwa kwe-thermal?

Ukudinwa kwe-Thermal kubangelwa ubushushu obuphezulu ngenxa yempembelelo kunye nokungqubuzana phakathi kweengcebiso zemigodi ye-tungsten carbide, enokuphakama malunga ne-700 ° C. Inokubonwa ngokubonakala kwamaqhosha e-tungsten carbide xa kukho ukuqhekeka kwe-semi-stable cracks ebusweni bamazinyo amaqhosha. Ukudinwa okukhulu kwe-thermal kuya kuwonakalisa ngokupheleleyo amaqhosha e-carbide e-cemented kwaye wenze i-drill bit igugile.

Iingcebiso

1. Sinokunciphisa umxholo we-cobalt kwi-alloy ukunciphisa i-coefficient yokwandisa i-thermal yamaqhosha e-tungsten carbide;

2. Sinokunyusa ubungakanani bengqolowa ye-tungsten carbide powder ukunyusa i-thermal conductivity ukwenzela ukuba ukushisa okuphezulu okubangelwa ngexesha lokungqubuzana kunokukhululwa ngexesha;

3. Singasebenzisa ulwakhiwo olungelulo olwahlukileyo lwenkozo yeWC ukuze siqinisekise ukuxhathisa okufanelekileyo kokudinwa kwe-thermal, ukumelana nokunxiba, kunye nokuqina;

4. Singakwazi ukuyila kwakhona i-drill bits ukunciphisa indawo evelele yeqhosha;

3. Ukuphalaza

Yintoni i-spalling?

I-Spalling ligama elisetyenziselwa ukuchaza iindawo zekhonkrithi eziqhekekileyo kunye ne-delaminated kwi-substrate. Kwishishini le-carbide enesamente, libhekisa kwimodi yokungaphumeleli. Umda wokudibanisa phakathi kwamaqhosha e-carbide e-cemented kunye nelitye liphantsi kwamandla angalinganiyo, kwaye ukuqhekeka kwenziwa phantsi kwesenzo esiphindaphindiweyo sale mikhosi. Ukuqina kwe-alloy kuphantsi kakhulu ukukhusela ukuqhekeka ekwandiseni, okubangelwa ukuchithwa kwamaqhosha e-tungsten carbide.

Kuloo maqhosha e-carbide enziwe ngesamente enobulukhuni obuphezulu kunye nokuqina okuphantsi, ukutshatyalaliswa okucacileyo kwenzeka, okuya kunciphisa kakhulu ubomi be-drill bit. Ubungakanani be-spalling yamaqhosha e-tungsten carbide ihambelana nokubunjwa kwe-alloy, ubukhulu bengqolowa ye-WC, kunye nentsingiselo yamahhala yesigaba se-cobalt.

Iingcebiso

Isitshixo kulo mbandela yindlela yokunyusa ukuqina kwamaqhosha e-carbide enesamente. Kwimveliso, sinokuphucula ukuqina kwamaqhosha e-carbide e-cemented ngokunyusa umxholo we-cobalt we-alloy kunye nokucocwa kweenkozo zeWC.

4. Iintanda zangaphakathi

Ziziphi iintanda zangaphakathi?

Ukuqhekeka kwangaphakathi kukuqhekeka okuvela kwisakhiwo sangaphakathi se-tungstenamaqhosha e-carbide, ekwabizwa ngokuba kukungaphumeleli kokubulala kwangaphambili. Kukho iindawo ezigudileyo, ezikwabizwa ngokuba ziindawo zesibuko, kunye neendawo ezirhabaxa, ezikwabizwa ngokuba zii-jaggies parts, kwindawo yokuphuka. Umthombo wokuqhekeka unokufumaneka kwinxalenye yesibuko.

Iingcebiso

Njengoko ukuqhekeka kwangaphakathi kubangelwa ikakhulu ngamaqhosha e-carbide ene-cemented ngokwabo, indlela yokuphepha ukuchithwa kwangaphakathi kukuphucula umgangatho wamaqhosha e-tungsten carbide ngokwabo. Singakwazi ukulungelelanisa i-sintering yoxinzelelo, kunye noxinzelelo olushushu lwe-isostatic kunye nonyango lobushushu emva kokuba sintering.

5. Ukuqhekeka kwamalungu angabonakaliyo

Yintoni ukwaphuka kwamalungu angavezwanga?

Xa senza amaqhosha e-tungsten carbide ngendlela engafanelekanga, ukuphuka kweengxenye ezingabonakaliyo kuya kwenzeka. Kwaye kunokubangelwa kukuxinzezeleka okukhulu koxinzelelo oluvela kwimilo engaphandle-kokujikeleza komngxuma wegiya esisigxina kunye nezinyo lebhola elibangela ukuba uxinzelelo lugxininise kwindawo ethile kumzimba weqhosha. Ukuqhekeka okwenzeka apho umngxuma ungekho nzulu, iintanda ziya kusasazeka ngokukhawuleza ngokugoba okuncinci, kwaye ekugqibeleni, zenze indawo egudileyo. Kwiintanda ezivela kwindawo enzulu ye-drill bits hole, ukuqhekeka kuya kubangela ukuba indawo ephezulu yeqhosha yahlulwe ngokude.

Iingcebiso

1. Qinisekisa ukugudiswa kwamazinyo ebhola emva kokusila, akukho ngaphandle kokujikeleza, akukho zintanda zokusila;

2. i-bottom of the tooth hole kufuneka ibe nesimo esifanelekileyo sokuxhasa esihambelana nomgangatho ophantsi weqhosha;

3. khetha i-diameter yezinyo efanelekileyo kunye nedayamitha yomngxuma xa ucinezela okubandayo okanye ukufakwa okutshisayo Isixa esihambelanayo.

6. Ukucheba ukwaphuka

Yintoni ukuqhekezwa kokucheba?

Ukuqhekeka kwe-shear kubhekiselele ekuqhekekeni kunye / okanye ukuchithwa kwempahla ngenxa yokusetyenziswa kwamandla oxinzelelo kumphezulu wayo. I-shear fracture ye-tungsten carbide yisiphumo samaqhosha e-tungsten e-carbide ahlala evezwe ngokucinezela kunye noxinzelelo lwe-shear ngaphezu kwemida ye-tungsten carbide inokumelana. Ngokubanzi, ukwaphuka kwe-chear akukho lula ukufunyanwa, kwaye kusenokusebenza emva kokuba kukho ukwaphuka. Ukuqhekeka kwe-shear kuqhelekile ukubonakala kwincam yetshizili.

Iingcebiso

Ukunciphisa ukuphuka kwe-chear, sinokujikeleza amaqhosha e-carbide e-cemented, kunye nokuyila kwaye ukhethe isakhiwo esifanelekileyo se-drill bit.

7. Ukuqhekeka komphezulu

Yintoni iintanda?

Ukuqhekeka komphezulu kuveliswa emva komthwalo ophezulu we-frequency kunye nezinye iindlela zokungaphumeleli. Ukuqhekeka okuncinci kumphezulu kuya kwandiswa ngokukhawuleza. Ibangelwa yifom yesakhiwo, indlela yokugaya i-drill bits, indawo yamazinyo eqhosha le-tungsten carbide, kunye nesakhiwo selitye eliza kuqhutyelwa.

Iingcebiso

Sinokunciphisa umxholo we-cobalt phezu kokunyusa ukuqina kunye nokuphucula ukuqina kwamaqhosha emigodi ye-tungsten carbide.

Ukulandela iindlela zokungaphumeleli kunye neengcebiso, unokuqonda ngakumbi ukuba kutheni amaqhosha akho e-tungsten carbide engaphumeleli emsebenzini. Ngamanye amaxesha, unokufumanisa ukuba kunzima ukufumanisa ukuba ngowuphi owona mba uphambili malunga namaqhosha akho e-tungsten carbide, nangona uqhelene nalo lonke uhlobo lwemowudi yokungaphumeleli kuba akukho sizathu esinye kuphela esenza ingqiqo.

Njengomenzi weqhosha le-tungsten carbide, indlela yokusombulula imiba yabathengi malunga nokunxiba kwe-tungsten carbide yimpendulo yethu. Siza kuhlalutya amatyala, sifumane ingxaki, kwaye sinike abathengi bethu isisombululo esingcono.
