Icandelo ledayimani ngumzimba osebenzayo we-diamond saw blade. Intloko yokusika isarha yedayimani yenziwe ngedayimani kunye nebhinda yematrix. Idayimani yinto enzima kakhulu esebenza njengento yokusika. I-matrix binder idlala indima yokulungisa idayimani. Iqulunqwe ngumgubo wensimbi olula okanye i-alloy powder yensimbi Ukuqulunqwa, iingoma ezahlukeneyo zibizwa ngokuba ziifomyula, kwaye iifomyula ziyahluka kwiidayimani ngokweendlela ezahlukeneyo zokusetyenziswa.

1. Ukukhethwa kobukhulu besuntswana ledayimani

Xa ubukhulu besuntswana ledayimani burhabaxa kunye nobungakanani besuntswana elinye, intloko yesarha yesarha ibukhali kwaye ukusebenza kakuhle kwedayimani kuphezulu, kodwa amandla okugoba e-agglomeration yedayimani ayancipha; xa ubungakanani besuntswana ledayimani lilungile okanye ubungakanani bamasuntswana arhabaxa kwaye acolekileyo buxutywe, intloko yesarha yesarha inokuqina okuphezulu, kodwa ayisebenzi kakuhle. Ukuthathela ingqalelo le miba ingentla, kufaneleka ngakumbi ukukhetha ubungakanani besuntswana ledayimane le-50/60 mesh.

2. Ukukhethwa koxinaniso lokusasazwa kwedayimani

Ngaphakathi koluhlu oluthile, xa ugxininiso lwedayimane lutshintsha ukusuka phantsi ukuya phezulu, ubukhali kunye nokusebenza kakuhle kwe-saw blade kuya kuncipha ngokuthe ngcembe, ngelixa ubomi benkonzo buya kwandisa ngokuthe ngcembe; kodwa ukuba ugxininiso luphezulu kakhulu, i-saw blade iya kuba buthuntu. Kwaye ukusetyenziswa koxinaniso oluphantsi, ubungakanani be-particle coarse, ukusebenza kakuhle kuya kuphuculwa. Ukusebenzisa imisebenzi eyahlukeneyo yecandelo ngalinye lentloko yomsiki ngexesha lokusarha, kusetyenziswa ugxininiso olwahlukileyo (oko kukuthi, ugxininiso olusezantsi lunokusetyenziswa kumaleko aphakathi kuluhlu olunezintlu ezintathu okanye ngaphezulu kwesakhiwo somaleko), kwaye kwakhiwa umjelo ophakathi. intloko yomsiki ngexesha lenkqubo yokubona, enefuthe elithile. Kuyinzuzo ukukhusela i-saw blade ukuba ingaphambuki, ngaloo ndlela iphucula umgangatho wokulungiswa kwamatye.

3. Ukukhethwa kwamandla edayimani

Amandla edayimani luphawu olubalulekileyo lokuqinisekisa ukusebenza kokusika. Amandla aphezulu kakhulu aya kwenza ukuba i-crystal ingabi lula ukuphuka, iinkozo eziqhekezayo ziya kuphononongwa ngexesha lokusetyenziswa, kwaye ubukhali buya kuncipha, kubangele ukuwohloka kokusebenza kwesixhobo; xa amandla edayimani enganele, aya kuphuka ngokulula emva kokuchaphazeleka, kwaye kunzima ukuthwala uxanduva olunzima lokusika. Ngoko ke, amandla kufuneka akhethwe kwi-130-140N

4. Ukukhethwa kwesigaba sokubopha

Ukusebenza kwe-saw blade akuxhomekeke kuphela kwidayimane, kodwa ekusebenzeni ngokubanzi kwezinto ezidibeneyo ze-diamond saw blade kunye nentloko ye-cutter eyenziwe yintsebenziswano efanelekileyo ye-binder. Kwizinto zamatye ezithambileyo ezifana ne-marble, iimpawu zomatshini zentloko ye-cutter kufuneka zibe ngaphantsi, kwaye izibophelelo ezisekelwe kubhedu zinokusetyenziswa. Nangona kunjalo, ukushisa kwe-sintering ye-binder-based binder iphantsi, amandla kunye nobunzima buphantsi, ubunzima buphezulu, kwaye amandla okudibanisa nedayimani aphantsi. Xa i-tungsten carbide (WC) yongezwa, i-WC okanye i-W2C isetyenziswe njengentsimbi ye-skeleton, kunye nenani elifanelekileyo le-cobalt ukuphucula amandla, ubunzima kunye neempawu zokudibanisa, kunye nenani elincinci le-Cu, i-Sn, i-Zn kunye nezinye izinyithi eziphantsi. indawo yokunyibilika kunye nobulukhuni obuphantsi bongezwa kwi-bonding Mutually. Ubungakanani beqhekeza lezithako eziphambili kufuneka bube ngcono kune-200 mesh, kwaye ubungakanani beqhekeza lezithako ezongezelelweyo kufuneka bube ngcono kune-300 mesh.

5. Ukukhethwa kwenkqubo ye-sintering

Njengoko iqondo lokushisa lisanda, iqondo lokuxinana kwesidumbu liyenyuka, kwaye amandla okuguquguquka nawo ayanda, kunye nokwandiswa kwexesha lokubamba, amandla okuguquguquka kwe-carcass engenanto kunye ne-diamond agglomerates kuqala ukunyuka kwaye emva koko kuyancipha. I-Sintering kwi-800 ° C ye-120s ukuhlangabezana neemfuno zokusebenza.
