Kule mihla, ukususa kuphela umphezulu weendawo zesinyithi akwanelanga. Abasebenzisi abaninzi kufuneka bafake iifilitha emaphethelweni eendawo zesinyithi. Kodwa ngaba uyazi ubungakanani bokujikelezisa? Ungawufumana njani umlinganiselo ofanelekileyo wefillet?
Impendulo ixhomekeke kwinjongo yefillet. Ishishini elicubungula i-arhente kufuneka licubungule iindawo zesinyithi ngokweemfuno zomzobo. Ngokubanzi, ezi nkcukacha kufuneka zichaneke kwaye zingatshintshi. Ukuba kuboniswe kumzobo wemveliso ukuba ifillet kufuneka ijikelezwe, iinkcukacha ze-chamfer ziya kuba nefuthe elikhulu kwixabiso lomsebenzi. Ke ngoko, nokuba kumenzi ngokwakhe okanye kushishino olucubungulayo, kubaluleke kakhulu ukukhetha ngokuchanekileyo ubungakanani be-chamfer efanelekileyo.
Ukuhlangabezana neemfuno njengesiseko, kancinci kangangoko
Ukuqinisekisa ukusetyenziswa ngokukhuselekileyo nangokufanelekileyo kwezixhobo zokucubungula ezisezantsi komlambo, iindawo zesinyithi kufuneka zibe bushelelezi kwaye zingabi naziqhushumbisi. Ezi zixhobo ezisezantsi komlambo zinokuba zii-gate presses, oomatshini bokugoba okanye oomatshini bokulinganisa. Ngaphambi kokugoba okanye ukulinganisa, ukuba izinto azinazo iziqhushumbisi, akukho mfuneko yokujikelezisa, kuba i-leveling roller idla ngokonakala kuphela yi-burr ephakanyisiweyo. Oku kuyafana nakwezinye izixhobo ezifana nezixhobo zokujika kunye ne-milling cutters. Ke ngoko, iindawo ezingenazo iziqhushumbisi zifanelekile ngakumbi ekucutshungulweni okulandelayo.
Ukuze kuthintelwe ukukrwelwa kwabasebenzi, amava abonise ukuba kufuneka i-chamfer eyi-0.1mm kuphela ukuqinisekisa ukhuseleko. Kwaneeglavu zelatex, iipayipi zomoya okanye iintambo ezihlala zichukumisa imiphetho yeenxalenye zesinyithi aziyi konakaliswa ziindawo zesinyithi ezinoluhlu olujikelezayo olungaphantsi kwe-0.1mm.
Xa kuqwalaselwa uphahla, izinto ezichaphazelayo ziba nzima kwaye zahluke. Eyokuqala luhlobo lophahla (i-KTL, umgubo, ipeyinti emanzi), uhlobo kunye nomgangatho wophahla, kwaye emva koko iiparameter zezixhobo, ezinje ngonyango lwangaphambi konyango, ixesha lokomisa okanye ubushushu bokomisa, kude kube kukubekwa kokugqibela kwemveliso. Ezi zinto, kunye nerediyasi yomphetho, zidlala indima ebalulekileyo kwixesha lokukhusela umhlwa. Ke ngoko, ubungakanani be-chamfer efanelekileyo kufuneka bumiselwe ngovavanyo ukuze kwandiswe ixesha lokukhusela ukubola. Kakade ke, zonke ezinye izinto ezichaphazelayo kufuneka zingatshintshi kuvavanyo.
Ubuncinane be-chamfer ye-0.5 mm inika uqweqwe oluthembekileyo
Ngokutsho kwe-DIN EN ISO 9227:2017, “uvavanyo lwe-neutral salt spray NSS” ludla ngokusetyenziswa njengendlela yokuvavanya ukhuseleko lokugqwala. Inkqubo yokugqwala iqwalaselwa ngokuhamba kwexesha. Ukongeza, icandelo elinqamlezileyo linokwenziwa ukubonisa utshintsho lobukhulu bengubo, ukuze kulinganiswe ubungakanani bokujikeleza kwesampuli (kungenziwa umlinganiselo owongezelelweyo ukuba kuyimfuneko). Ezi sampuli zinokubonisa ngokucacileyo ukuba imilo ye-radius inefuthe kubukhulu bengubo. Kwimeko ye-fillet engalinganiyo, ubukhulu bengubo buyehla kwi-curvature ephezulu. Ke ngoko, kunokugqitywa kwelokuba isiphumo esifanelekileyo sokujikelezisa umphetho sinokufunyanwa nge-radius efanayo.
Umgangatho esinokuwufumana koku (umzekelo, kwizakhiwo zentsimbi okanye kwizakhiwo ezikude nolwandle) ufuna ukuba irediyasi ejikelezayo yomphetho wezinye iindawo zesinyithi zesheyiti ibe yi-2.0mm nangaphezulu. Nangona kunjalo, uninzi lwezicelo ezisebenzayo zibonisa ukuba ukunamathela okuhle kokugquma kunokufunyanwa logama nje kusenziwa i-rounding ye-0.5mm kwiindawo zesinyithi zesheyiti. Ngenxa yokuba ubungakanani be-chamfer kunye neendleko zesixhobo eziphumayo ziya kwanda ngokulinganayo ngokonyuka kwerediyasi yomphetho, kuyimfuneko ukuba abasebenzisi bafumane ubungakanani obuchanekileyo bokujikeleza ukuqinisekisa umatshini othembekileyo nongabizi kakhulu. Oko kukuthi: ukuhlangabezana neemfuno, kancinci kangangoko kunokwenzeka.
