Kuongororwa kweCore Performance Parameters yeCemented Carbide Chisels

Iyo simende ye carbide chisel ndiyo moyo wemazuva ano ekuchera matombo maturusi, uye kuita kwayo kunotaridza zvakananga kudhirowa uye hupenyu hwezvishandiso. Kusarudza nesainzi uye kushandisa machisel aya, zvakakosha kuti unzwisise zvakadzama zvinotevera epakati pekuita ma paramita.

1. Kuoma: Chiratidzo Chekutanga chekupikisa Kupinda uye Kupfeka

Kuomarara iparameter inoyera kugona kwesemented carbide chisel's pamusoro kuramba kupinda kana kukweshwa nezvinhu zvekunze, zvinowanzo ratidzwa muRockwell Hardness (HRA). Iyo inonyanya kutsanangurwa nekuoma, saizi yezviyo, uye kugovera kwe tungsten carbide (WC) mukati mezvinyorwa. Kuomarara kwepamusoro kunoreva kuti chisel inogona kunyatsoruma mudombo rakaoma uye kuramba kusakara kubva pakucheka kwedombo, nekudaro ichichengetedza kupinza uye kuwedzera hupenyu hwesevhisi. Mumaumbirwo ematombo anonyandura, kuomarara ndiyo danho rekutanga rekusarudza.

2. Kuoma: Chivimbiso Chinokosha Chinopesana Nemigumisiro uye Kutsemuka

Kuoma kunomiririra kugona kwechinhu kutora simba pasina kutsemuka. Kuchera ndeye yakakwirira-frequency, yakanyanya-stress maitiro maitiro. Kana chisel chikashaya kusimba kwakakwana, chinowanzo cheka, kutsemuka, kana kutokundikana zvachose. Kuoma kunonyanya kuenderana nezviri mukati uye kugovera kweiyo cobalt (Co) binder chikamu. Kazhinji, iyo yakakwira cobalt yemukati inoguma nekuoma kuri nani. Mune akatyoka uye heterogeneous dombo maumbirwo, kuomarara kwepamusoro ndiyo nzira yekudzivirira yekukurumidza kutadza kwechisel.

3. Flexural Strength: Chiyero cheKutakura-Kutakura Kukwanisa

Flexural simba ndiyo yakanyanya kushushikana iyo chinhu chinogona kumira chisati chatsemuka pasi pemutoro unokotama. Iyo inonyatsoratidza iyo "simba" uye "kuoma" kweiyo simende carbide uye yakanangana nekugona kwechisel kuramba kutyoka pasi pesimba rakakura rekuita uye nguva dzakaoma dzekukotama. Chisel ine simba repamusoro rakafanana nekuve ne "musana" wakasimba, uchiigonesa kutsungirira zvakatsiga kushushikana kwakasiyana-siyana kunosangana nemamiriro ekushanda akaomarara uye kuve nechokwadi chekuchengetedzwa kwekushanda uye kuvimbika.

4. Fracture Toughness: The Resistance to Crack Propagation

Kuomarara kwefracture chiratidzo chepamusoro chekuomarara, zvichinyanya kureva kugona kwechinhu chine micro-makorokoza kurwisa kusagadzika kupararira. Mukugadzira kunoshanda, zvirema zvidiki mukati mezvinyorwa hazvidzivisike. Kuomarara kwepamusoro kunoreva kuti kunyangwe madiki-diki akakura, haafanire kukurumidza kupararira uye kukonzera kutadza zvachose. Iyi parameter yakakosha pakuchengetedza chishandiso pasi pemamiriro akanyanya anosanganisira eccentric mitoro (semuenzaniso, kutsvedza zvishoma).

Mhedziso: The Balance and Synergy of Properties

Zvakakosha kusimbisa kuti aya ma parameters haapo ari ega asi anoenderana uye anowanzo sanganisira kutengeserana. Iko kutsvaga kuoma kwakanyanya kunowanzo kunouya nemutengo wekuderedzwa kuomarara uye kusimba, uye zvinopesana. Semuyenzaniso, machisero ane zviyo zvakatsetseka uye yakaderera cobalt zvemukati anoratidza kuomarara kwakanyanya uye kupfeka kuramba asi kusimba kwakaderera. Sezvineiwo, machisero ane coarse zviyo uye yakakwira cobalt zvemukati zvinopa zvirinani kuomarara uye kusimba asi kwakati kwakadzikira kuoma.

Naizvozvo, kusarudza simende ye carbide chisel haisi yekutevera iyo yekupedzisira mune imwechete parameter. Pane kudaro, ndezvekutsvaga yakaringana chiyero pakati pekuomarara, kuomarara, uye simba zvichibva pane chaiwo magadzirirwo ematombo (semuenzaniso, angave akaoma uye akasimba kana akatsemuka uye akaomarara). Iyi nzira inowana hupenyu hurefu hwebasa uye nekubudirira kwepamusoro.
