Izimbangela Nezinyathelo Zokulwa Ne-Cemented Carbide Tool Chipping

2024-01-04

Izimbangela nezinyathelo zokuphikisa ithuluzi le-carbide elifakwe usimende:

Ukugqokwa nokukhishwa kwe-Carbide Inserts kungenye yezinto ezivamile. Lapho ukufakwa kwe-carbide kugqokwa, kuzothinta ukunemba kwemishini, ukusebenza kahle kokukhiqiza, ikhwalithi ye-workpiece, njll.; Inqubo yomshini ihlaziywa ngokucophelela ukuze kutholwe imbangela yokufakwa kokugqoka.

Causes and Countermeasures of Cemented Carbide Tool Chipping

1) Ukukhetha okungalungile kwamabanga we-blade kanye nokucaciswa, njengokujiya kwe-blade mncane kakhulu noma amamaki aqine kakhulu futhi ama-brittle akhethelwa ukukhanda amakhanda.

Izinyathelo zokulwa: Khulisa ukujiya kwe-blade noma faka i-blade iqonde phezulu, bese ukhetha ibanga elinamandla okugoba aphezulu kanye nokuqina.

2) Ukukhetha okungalungile kwepharamitha yejiyomethri yethuluzi (njengama-engeli amakhulu kakhulu angaphambili nangemuva, njll.).

Izinyathelo Zokulwa: Dizayina kabusha ithuluzi ngezici ezilandelayo. ① Nciphisa ngokufanelekile ama-engeli angaphambili nangemuva; ② Sebenzisa ukuthambekela konqenqema olukhudlwana; ③ Yehlisa i-engeli enkulu yokwehliswa; ④ Sebenzisa i-chamfer engalungile enkulu noma i-arc enqenqemeni; ⑤ Gaya unqenqema lokusika ukuze uthuthukise ithiphu lethuluzi.

I-3) Inqubo ye-welding ye-blade ayilungile, okuholela ekucindezelekeni okweqile kwe-welding noma imifantu ye-welding.

Izinyathelo zokulwa: ①Gwema ukusebenzisa isakhiwo se-groove esinezinhlangothi ezintathu esivaliwe; ②Ukukhetha okulungile kwesidayisi; ③Gwema ukusebenzisa ukushisa kwelangabi le-oxyacetylene ukushisela, futhi ufudumale ngemva kokushisela ukuze uqede ukucindezeleka kwangaphakathi; ④Sebenzisa isakhiwo sokubopha ngomshini ngangokunokwenzeka

I-4) Indlela yokucija engalungile izobangela ukucindezeleka kokugaya kanye nemifantu yokugaya; ukudlidliza kwamazinyo ngemva kokulola i-PCBN milling cutter inkulu kakhulu, kangangokuthi amazinyo ngamanye agcwele ngokweqile, futhi ummese nawo uzoshaywa.

Izinyathelo zokulwa: 1. Sebenzisa ukugaya ngezikhathi ezithile noma ukugaya isondo ledayimane; 2. Sebenzisa isondo lokugaya elithambile futhi ulinqume njalo ukuze ugcine isondo lokugaya libukhali; 3. Naka ikhwalithi yokulola futhi ulawule ngokuqinile ukudlidliza kwamazinyo omshini wokusika.

5) Ukukhethwa kwenani lokusika akunangqondo. Uma inani likhulu kakhulu, ithuluzi lomshini lizoba yisicefe; lapho ukusika ngezikhathi ezithile, isivinini sokusika siphezulu kakhulu, izinga lokudla likhulu kakhulu, futhi isibonelelo esingenalutho asifani, ukujula kokusika kuncane kakhulu; ukusika insimbi ephezulu ye-manganese Ngezinto ezibonakalayo ezinokuthambekela okuphezulu kokusebenza kanzima, izinga lokudla lincane kakhulu, njll.

I-Countermeasure: Khetha kabusha inani lokusika.

6) Izizathu zesakhiwo ezifana nendawo engaphansi engalingani yenkundla yommese yethuluzi eliboshwe ngomshini noma insimbi ende kakhulu ephumela ngaphandle.

Izinyathelo zokulwa: ① Nquma indawo engaphansi ye-groove yamathuluzi; ② Hlela ukuma kwenozi yamanzi okusika ngokunengqondo; ③ Engeza i-gasket ye-carbide enosimende ngaphansi kwe-blade ye-arbor eqinile.

7) Ukugqoka kwamathuluzi okweqile.

Izinyathelo zokulwa: Shintsha ithuluzi ngesikhathi noma shintsha unqenqema lokusika.

I-8) Ukugeleza kwamanzi okusika akwanele noma indlela yokugcwalisa ayilungile, okwenza i-blade ishise futhi iqhekeke.

Izinyathelo zokulwa: ① Khulisa izinga lokugeleza koketshezi olusikayo; ② Hlela indawo yokusika umlomo wombhobho wamanzi ngendlela enengqondo; ③ Sebenzisa izindlela zokupholisa ezisebenzayo ezifana nokupholisa isifutho ukuze uthuthukise umphumela wokupholisa; ④ Sebenzisa * ukusika ukuze unciphise umthelela we-blade.

9) Ithuluzi alifakiwe ngendlela efanele, njengokuthi: ithuluzi lokusika lifakwe phezulu kakhulu noma liphansi kakhulu; i-face milling cutter isebenzisa i-asymmetric down milling, njll.

I-Countermeasure: Faka kabusha ithuluzi.

10) Ukuqina kwesistimu yenqubo kubi kakhulu, okuholela ekudlidlizeni okusika ngokweqile.

Izinyathelo eziphikisanayo: ① Khulisa ukusekelwa okuyisizayo kocezu lokusebenza ukuze uthuthukise ukuqina kokugoqa kocezu lokusebenza; ② Yehlisa ubude be-overhang bethuluzi; ③ Nciphisa ngokufanelekile i-engeli yokususa yethuluzi; ④ Sebenzisa ezinye izindlela zokuqeda ukudlidliza.

11) Ukusebenza ngokunganaki, njengokuthi: lapho ithuluzi linqamula phakathi nendawo yokusebenza, isenzo sinobudlova kakhulu;

I-Countermeasure: Naka indlela yokusebenza.
