Yintoni i-hammer drill?

Ukuthetha ngamasuntswana ombane wehamile, masiqale siqonde ukuba yintoni isando sombane?

Ihamile yombane isekelwe kwi-drill yombane kwaye yongeza ipiston enentonga yokudibanisa i-crankshaft eqhutywa yinjini yombane.Icinezela umoya ngasemva naphambili kwi-cylinder, ibangela utshintsho lwexeshana kuxinzelelo lomoya kwi-cylinder.Njengoko uxinzelelo lomoya lutshintsha, isando sibuyela kwi-cylinder, elilingana nokusebenzisa isando ngokuqhubekayo ukucofa i-drill bit ejikelezayo.Amasuntswana okubhola ngesando anokusetyenziswa kwiindawo ezibhityileyo kuba avelisa intshukumo ekhawulezayo ebuyelanayo (iimpembelelo zarhoqo) ecaleni kombhobho wokubhoboza njengoko zijikeleza.Ayifuni misebenzi mininzi yezandla, kwaye inokwemba imingxuma kwikhonkrithi yesamente namatye, kodwa hayi intsimbi, umthi, iplastiki okanye ezinye izinto.

Ukungalungi kukuba i-vibration inkulu kwaye iya kubangela iqondo elithile lomonakalo kwizakhiwo ezijikelezileyo.Kwimivalo yensimbi kwisakhiwo sekhonkrithi, i-drill bits eqhelekileyo ayikwazi ukudlula kakuhle, kwaye ukunyakaza kuya kuzisa uthuli oluninzi, kwaye ukunyakaza kuya kuvelisa ingxolo eninzi.Ukungaphumeleli ukuthwala izixhobo ezifanelekileyo zokukhusela kunokuba yingozi empilweni.

Yintoni intwana yehamile?Banokwahlulwa ngokufanelekileyo ngeentlobo ezimbini zokubamba: i-SDS Plus kunye ne-Sds Max.

I-SDS-Plus - Imingxuma emibini kunye neegrooves ezimbini ezijikelezayo

Inkqubo ye-SDS eyaphuhliswa yi-BOSCH ngo-1975 sisiseko sezinto ezininzi zanamhlanje zombane zokugaya ihamile.Ayaziwa ukuba i-SDS drill bit yasekuqaleni yayibukeka njani.Inkqubo eyaziwayo ngoku yeSDS-Plus yaphuhliswa ngokudibeneyo nguBosch noHilti.Ngokuqhelekileyo iguqulelwe njenge "Spannen durch System" (inkqubo yokutshintsha ngokukhawuleza i-clamping), igama layo lithathwe kwibinzana lesiJamani elithi "S tecken - D rehen - Safety".

Ubuhle be-SDS Plus kukuba utyhala nje i-drill bit kwi-spring-loaded drill chuck.Akukho kuqiniswa okufunekayo.Intwana ye-drill ayimiliselwanga ngokuqinileyo kwi-chuck, kodwa isilayidi ngasemva naphambili njengepiston.Xa ujikeleza, i-drill bit ayiyi kuphuma kwi-chuck ngenxa yeedimples ezimbini kwi-shank yesixhobo esijikelezayo.I-SDS shank drill bits ye-hammer drill isebenza ngakumbi kunezinye iindidi ze-shank drill bits ngenxa yemigodi yazo emibini, evumela ukubethelwa ngesantya esiphezulu kunye nokuphucula ukusebenza kakuhle.Ngokukodwa, i-hammer drill bits esetyenziselwa ukugaya i-hammer kumatye kunye nekhonkrithi inokudityaniswa kwi-shank epheleleyo kunye nenkqubo ye-chuck eyenziwe ngokukodwa kule njongo.Inkqubo yokukhupha ngokukhawuleza ye-SDS yindlela esemgangathweni yoncamathiselo yeebhithi zanamhlanje zokubhola isando.Ayiboneleli kuphela indlela ekhawulezayo, elula nekhuselekileyo yokucinezela isuntswana le-drill, ikwaqinisekisa ugqithiso lwamandla alona lufanelekileyo kwi-drill bit ngokwayo.

I-SDS-Max – isiphatho esingqukuva semingxuma emihlanu

I-SDS-Plus nayo inemida.Ngokubanzi, i-handle diameter ye-SDS Plus yi-10mm, ngoko ke ukugrumba imingxunya emincinci naphakathi akuyongxaki.Xa kusetyenzwa imingxuma emikhulu okanye enzulu, itorque engonelanga inokubangela ukuba i-drill bit ibambeke kwaye isiphatho siphuke ngexesha lokusebenza.I-BOSCH iphuhlise i-SDS-MAX esekelwe kwi-SDS-Plus, ene-grooves emithathu kunye nemigodi emibini.Umqheba we-SDS Max unemiqolo emihlanu.Kukho iindawo zokubeka ezintathu ezivulekileyo kunye neendawo zokubeka ezimbini ezivaliweyo (ukuthintela i-drill bit ekubhabheni ngaphandle).Eyaziwa ngokuba ziigrooves ezintathu kunye nemingxuma emibini engqukuva isiphatho, ekwaziwa ngokuba yimingxuma emihlanu engqukuva.Isibambo se-SDS Max sinobubanzi obuyi-18 mm kwaye sikulungele kangcono umsebenzi onzima kune-SDS-Plus handle.Ke ngoko, isibambo se-SDS Max sinetorque eyomeleleyo kune-SDS-Plus kwaye ilungele ukusebenzisa i-diameter enkulu yempembelelo ye-drill bits kwimisebenzi emikhulu kunye nenzulu yomngxuma.Abantu abaninzi babekhe bakholelwa ukuba inkqubo ye-SDS Max iza kuthatha indawo ye-SDS endala.Enyanisweni, ukuphuculwa okuphambili kwenkqubo kukuba i-piston ine-stroke ende, ngoko xa ibetha i-drill bit, impembelelo yomelele kwaye i-drill bit cuts ngokufanelekileyo.Ngaphandle kokuphuculwa kwenkqubo yeSDS, inkqubo yeSDS-Plus iya kuqhubeka isetyenziswa.I-SDS-MAX ye-18mm ye-shank idayamitha iphumela kwiindleko eziphezulu xa kusenziwa iisayizi ezincinci zokomba.Akunakuthiwa ithathe indawo ye-SDS-Plus, kodwa kunokuba ngumphelelisi.Iihamile zombane kunye ne-drills zisetyenziswa ngokuhlukileyo kwamanye amazwe.Kukho iintlobo zomqheba ezahlukeneyo kunye nezixhobo zamandla zobunzima behamile obahlukeneyo kunye nobukhulu besuntswana le-drill.

Ngokuxhomekeke kwimarike, i-SDS-plus yeyona nto ixhaphakileyo kwaye ngokuqhelekileyo ihlalisa i-drill bits ukusuka kwi-4 mm ukuya kwi-30 mm (5/32 kwi-1-1 / 4 in.).Ubude obupheleleyo 110mm, ubude obuninzi 1500mm.I-SDS-MAX idla ngokusetyenziswa kwimingxuma emikhulu kunye nokuchongwa.Amasuntswana e-Impact drill aphakathi kwe-1/2 intshi (13 mm) kunye ne-1-3/4 intshi (44 mm).Ubude bubonke buqhele ukuba yi-12 ukuya kwi-intshi ezingama-21 (300 ukuya kuma-530 mm).
