Uma sikhuluma ngezingcezu zikagesi zokubhoboza isando, ake siqale siqonde ukuthi iyini isando sikagesi?
Isando sikagesi sisekelwe ku-drill kagesi futhi sengeza ipiston enenduku yokuxhuma i-crankshaft eshayelwa injini kagesi.Icindezela umoya uye phambili naphambili kusilinda, okubangela izinguquko ngezikhathi ezithile kumfutho womoya kusilinda.Njengoba umfutho womoya ushintsha, isando siphindela kusilinda, okulingana nokusebenzisa isando ukuze ulokhu uthephe ibhithi lokubhola elizungezayo.Izingcezu zokubhola ngesando zingasetshenziswa ezingxenyeni eziphukayo ngoba zikhiqiza ukunyakaza okubuyelana ngokushesha (imithelela evamisile) eduze kwepayipi lokubhoboza njengoba lizungezisa.Ayidingi umsebenzi omningi wezandla, futhi ingabhoboza izimbobo zikasimende namatshe, kodwa hhayi insimbi, ukhuni, ipulasitiki noma ezinye izinto.
Okubi ukuthi ukudlidliza kukhulu futhi kuzodala izinga elithile lomonakalo ezakhiweni ezizungezile.Ngemigoqo yensimbi esakhiweni sikakhonkolo, ama-drill bits ajwayelekile awakwazi ukudlula kahle, futhi ukudlidliza kuzoletha uthuli oluningi, futhi ukudlidliza kuzokhipha umsindo omkhulu.Ukwehluleka ukuthwala izinto zokuzivikela ezanele kungaba yingozi empilweni.
Iyini insimbi yokubhola isando?Zingahlukaniswa cishe ngezinhlobo ezimbili zokubamba: i-SDS Plus ne-Sds Max.
I-SDS-Plus - Imigodi emibili nezibambo ezimbili eziyindilinga
Uhlelo lwe-SDS olwakhiwe yi-BOSCH ngo-1975 luyisisekelo sezingcezu eziningi zanamuhla zokubhola isando sikagesi.Akusaziwa ukuthi i-SDS drill bit yasekuqaleni yayibukeka kanjani.Isistimu eyaziwa manje ye-SDS-Plus yasungulwa ngokuhlanganyela yi-Bosch kanye no-Hilti.Ngokuvamile elihunyushwa ngokuthi "Isistimu ye-Spannen durch" (uhlelo lokushintsha ngokushesha), igama layo lithathwe egameni lesiJalimane elithi "S tecken - D rehen - Safety".
Ubuhle be-SDS Plus ukuthi umane uphushe i-drill bit ku-drill chuck elayishwe intwasahlobo.Akukho ukuqiniswa okudingekayo.I-drill bit ayigxilile ngokuqinile ku-chuck, kodwa islayida emuva naphambili njengepiston.Uma uzungezisa, i-drill bit ngeke ishelele iphume ku-chuck ngenxa yama-dimples amabili ku-shank yethuluzi eliyindilinga.Ama-SDS ama-shank drill bits wokubhoboza isando asebenza kahle kakhulu kunezinye izinhlobo zama-shank drill bits ngenxa yemisele yawo emibili, okuvumela ukushaya ngesando okushesha ngesivinini kanye nokusebenza kahle kokusando okuthuthukisiwe.Ikakhulukazi, izinsimbi zokubhoboza isando ezisetshenziselwa ukumba isando etsheni nakokhonkolo zingaxhunywa ohlelweni oluphelele lwe-shank ne-chuck olwenzelwe le njongo.Isistimu yokukhipha okusheshayo ye-SDS iyindlela yokunamathisela ejwayelekile yezingcezu zanamuhla zokubhola isando.Akugcini nje ngokuhlinzeka ngendlela esheshayo, elula nephephile yokucindezela i-drill bit, futhi iqinisekisa ukudluliswa kwamandla afanele kubhithi lokubhoboza uqobo.
I-SDS-Max - Isibambo esiyindilinga semigodi emihlanu
I-SDS-Plus nayo inemikhawulo.Ngokuvamile, ububanzi besibambo se-SDS Plus bungu-10mm, ngakho ukubhoboza izimbobo ezincane neziphakathi akuyona inkinga.Uma ubhoboza izimbobo ezinkulu noma ezijulile, i-torque enganele ingabangela ukuthi i-drill bit ibambeke futhi isibambo siphuke ngesikhathi sokusebenza.I-BOSCH ithuthukise i-SDS-MAX esekelwe ku-SDS-Plus, enemigodi emithathu nemigodi emibili.Isibambo se-SDS Max sinemifantu emihlanu.Kunezikhala ezintathu ezivulekile nezimbili ezivaliwe (ukuvimbela i-drill bit ukuba indize ngaphandle).Okuvame ukwaziwa ngokuthi ama-grooves amathathu kanye nesibambo esiyindilinga semigodi emibili, eyaziwa nangokuthi isibambo esiyindilinga esiyimigodi emihlanu.Isibambo se-SDS Max sinobubanzi obungu-18 mm futhi siwufanela kangcono umsebenzi osindayo kunesibambo se-SDS-Plus.Ngakho-ke, isibambo se-SDS Max sinetorque enamandla kune-SDS-Plus futhi ifanele ukusebenzisa amabhithi okubhoboza amadayimitha amakhulu ekusebenzeni kwemigodi emikhulu nejulile.Abantu abaningi bake bakholelwa ukuthi uhlelo lwe-SDS Max luzongena esikhundleni sohlelo oludala lwe-SDS.Eqinisweni, ukuthuthukiswa okuyinhloko kwesistimu ukuthi i-piston ine-stroke ende, ngakho-ke lapho ishaya i-drill bit, umthelela unamandla futhi i-drill bit isike ngokuyimpumelelo.Naphezu kokuthuthukiswa kwesistimu ye-SDS, uhlelo lwe-SDS-Plus luzoqhubeka lusetshenziswa.I-SDS-MAX's 18mm shank diameter iphumela ezindlekweni eziphakeme uma kwenziwa amasayizi amancane okubhoboza.Ngeke kushiwo ukuthi ithatha indawo ye-SDS-Plus, kodwa ingumphelelisi.Izando zikagesi kanye nama-drill asetshenziswa ngokuhlukile kwamanye amazwe.Kunezinhlobo ezahlukene zezibambo namathuluzi amandla ezisindo zesando ezihlukene kanye nosayizi bebhithi yokubhoboza.
Kuye ngemakethe, i-SDS-plus iyona evame kakhulu futhi ngokuvamile ivumela izinsimbi zokubhoboza kusuka ku-4 mm kuya ku-30 mm (5/32 in. kuya ku-1-1/4 in.).Ubude obuphelele 110mm, ubude obukhulu 1500mm.I-SDS-MAX ivamise ukusetshenziselwa izimbobo ezinkulu nokukhetha.Ama-drill bits ngokuvamile aphakathi kwe-intshi engu-1/2 (13 mm) kanye no-1-3/4 amayintshi (44 mm).Ubude bebonke ngokuvamile buyi-12 kuya ku-21 amayintshi (300 kuya ku-530 mm).
