Iimbangela kunye namanyathelo okuLawula iCemented Carbide Tool Chipping

2024-01-04

Cemented isixhobo se-carbide ukusika oonobangela kunye namanyathelo okuthintela:

Ukunxitywa kunye nokutshitshwa kokufakwa kwe-carbide yenye yezinto eziqhelekileyo. Xa ukufakwa kwe-carbide kugugile, kuya kuchaphazela ukuchaneka komatshini, ukusebenza kakuhle kwemveliso, umgangatho womsebenzi, njl.; Inkqubo yomatshini ihlalutywa ngononophelo ukufumana ingcambu yesizathu sokufakela ukunxiba.

Causes and Countermeasures of Cemented Carbide Tool Chipping

I-1) Ukukhethwa okungafanelekanga kwamabakala e-blade kunye neenkcukacha, ezifana nobukhulu be-blade buncinci kakhulu okanye amabakala anzima kakhulu kunye ne-brittle akhethwe ngomatshini olukhuni.

Imilinganiselo yokulwa: Yandisa ubukhulu beblade okanye ufake iblade ngokuthe nkqo, kwaye ukhethe ibakala elinamandla okugoba aphezulu kunye nokuqina.

2) Ukukhetha okungafanelekanga kwesixhobo seeparameters zejometri (ezifana ne-angle enkulu yangaphambili nangasemva, njl.).

Amanyathelo okunqanda: Yila ngokutsha isixhobo kule miba ilandelayo. ① Nciphisa ngokufanelekileyo ii-engile zangaphambili nezingasemva; ② Sebenzisa utyekelo olukhulu olubi; ③ Nciphisa eyona engile yokwala; ④ Sebenzisa i-chamfer enkulu engalunganga okanye i-edge arc; ⑤ Gaya inguqu yokusika umgca wokuphucula isicatshulwa sesixhobo.

3) Inkqubo ye-welding ye-blade ayilunganga, okubangelwa uxinzelelo olugqithisileyo lwe-welding okanye i-welding cracks.

Amanyathelo okuchasa: ①Kuphephe ukusebenzisa ubume bomjelo omacala-ntathu avaliweyo; ②Ukhetho oluchanekileyo lwesolder; ③Kuphephe ukusebenzisa i-oxyacetylene yokufudumeza idangatye ukuwelda, kwaye uhlale ushushu emva kwe-welding ukuphelisa uxinzelelo lwangaphakathi; ④Sebenzisa ubume bomatshini bokubambelela kangangoko

4) Indlela engafanelekanga yokulola iya kubangela uxinzelelo lokugaya kunye nokugaya ukuqhekeka; ukungcangcazela kwamazinyo emva kokulola iPCBN yokusila i-milling cutter inkulu kakhulu, ukuze amazinyo ngamanye azaliswe, kwaye imela nayo iya kubetheka.

Amanyathelo okunqanda: 1. Sebenzisa okusila okwethutyana okanye ivili lokusila idayimani; 2. Sebenzisa ivili lokusila elithambileyo kwaye ulisike rhoqo ukugcina ivili lokusila libukhali; 3. Nika ingqalelo kumgangatho wokulola kwaye ulawule ngokungqongqo ukungcangcazela kwamazinyo okusika amazinyo.

5) Ukukhethwa kwexabiso lokusika akunangqiqo. Ukuba isixa sikhulu kakhulu, isixhobo somatshini siya kuba nesithukuthezi; xa usika i-intermittently, isantya sokusika siphezulu kakhulu, izinga lokutya likhulu kakhulu, kwaye isibonelelo esingenanto asifani, ubunzulu bokusika buncinci; ukusika intsimbi ephezulu ye-manganese Ngezixhobo ezinotyekelo oluphezulu lokusebenza ukuqina, izinga lokutya lincinci kakhulu, njl.

I-Countermeasure: Khetha kwakhona inani lokusika.

6) Izizathu zesakhiwo ezifana nomphezulu ongalinganiyo osezantsi wegroove yemela yesixhobo esibotshwe ngoomatshini okanye iblade ende kakhulu ephumela ngaphandle.

Imilinganiselo yokuchasana: ① Sika umphezulu osezantsi wegroove yesixhobo; ② Lungiselela indawo ye-nozzle yokusika amanzi ngokufanelekileyo; ③ Yongeza i-gasket ye-carbide enesamente phantsi kwe-blade ye-arbor eqinile.

7) Ukugqithiswa kwezixhobo zokusebenza.

I-Countermeasures: Guqula isixhobo ngexesha okanye ubuyisele umgca wokusika.

I-8) Ukuhamba kwamanzi okusika akwanelanga okanye indlela yokuzalisa ayilunganga, ibangela ukuba i-blade ifudumale kwaye iqhekeze.

Imilinganiselo yokuchasana: ① Yandisa isantya sokuhamba kolwelo olusikiweyo; ② Lungiselela indawo yokusika umbhobho wolwelo ngokufanelekileyo; ③ Sebenzisa iindlela zokupholisa ezisebenzayo ezifana nokupholisa isitshizi ukuphucula isiphumo sokupholisa; ④ Sebenzisa * ukusika ukunciphisa impembelelo kwi-blade.

9) Isixhobo asifakelwanga ngokuchanekileyo, njengale: isixhobo sokusika sifakwe phezulu kakhulu okanye sisezantsi kakhulu; i-face milling cutter ithatha i-asymmetric down milling, njl.

Countermeasure: Phinda ufake isixhobo.

I-10) Ukuqina kwenkqubo yenkqubo kubi kakhulu, kubangele ukungcangcazela okugqithisileyo.

Imilinganiselo yokuchasana: ① Yandisa inkxaso encedisayo yesixhobo sokusebenza ukuphucula ukuqina kokuqina kwesixhobo sokusebenza; ② Ukunciphisa ubude besixhobo; ③ Nciphisa ngokufanelekileyo i-engile yokususa isixhobo; ④ Sebenzisa amanye amanyathelo okuphelisa ukungcangcazela.

I-11) Ukusebenza ngokungakhathali, njengalokhu: xa isixhobo sinqumla phakathi kwendawo yokusebenza, isenzo sinobudlova kakhulu;

Countermeasure: Nika ingqalelo kwindlela yokusebenza.
