Chii chinonzi sando chibooresa?

Tichitaura nezvemagetsi sando yekubooresa, ngatitangei kunzwisisa kuti chii chinonzi sando yemagetsi?

Sando yemagetsi yakavakirwa pachibooreso chemagetsi uye inowedzera piston ine crankshaft yekubatanidza tsvimbo inotyairwa nemota yemagetsi.Inomanikidza mhepo kumashure nekudzoka mucylinder, zvichikonzera shanduko yenguva nenguva mukumanikidza kwemhepo mucylinder.Sezvo mweya wemhepo unochinja, sando inodzokera muhumburumbira, izvo zvakaenzana nekushandisa sando kuramba uchibaya chibooreso chinotenderera.Hammer drill bits inogona kushandiswa pane brittle parts nekuti inogadzira kukurumidza kudzoreredza mafambiro (zvinowanzoitika) pamwe nepombi yekuboora painotenderera.Haidi basa rakawanda remaoko, uye inogona kuboora maburi mukongiri yesamende nematombo, asi kwete simbi, huni, plastiki kana zvimwe zvinhu.

Izvo zvisingabatsiri ndezvokuti kuzununguka kwakakura uye kuchakonzera imwe nhanho yekukuvadza kune zvivakwa zvakapoteredza.Kune masimbi esimbi muchimiro chekongiri, akajairwa dhiri mabheti haagone kupfuura zvakanaka, uye vibration ichaunzawo guruva rakawanda, uye vibration inoburitsawo ruzha.Kutadza kutakura midziyo yekudzivirira yakakwana kunogona kuva nengozi kuutano.

Chii chinonzi sando drill bit?Ivo vanogona kunyatsosiyaniswa nemhando mbiri dzemubato: SDS Plus uye Sds Max.

SDS-Plus - Makomba maviri uye maviri magrooves akatenderedza mubato

Iyo SDS system yakagadziridzwa neBOSCH muna 1975 ndiyo hwaro hweakawanda emazuva ano emagetsi sando anodhirowa.Hazvichazivikanwe kuti yekutanga SDS drill bit yakaita sei.Iyo ikozvino inozivikanwa SDS-Plus system yakagadzirwa pamwe chete neBosch naHilti.Inowanzo shandurwa se "Spannen durch System" (kukurumidza-kuchinja clamping system), zita rayo rinotorwa kubva mumutsara wechiGerman "S tecken - D rehen - Safety".

Runako rweSDS Plus nderekuti unongosundidzira chibooreso muchirimo-chakaremerwa drill chuck.Hapana kuomesa kunodiwa.Iyo drill bit haina kusimba kune chuck, asi inotsvedza nekudzoka sepiston.Kana uchitenderedza, chibooreso hachizotsvedza kubva muchuck nekuda kwemadimples maviri pane yakatenderedza chishandiso shank.SDS shank drill bits yehammer drill inoshanda zvakanyanya kupfuura mamwe marudzi e shank drill bits nekuda kwe grooves yavo miviri, zvichibvumira kukurumidza kukurumidza-kumhanya nyundo uye kuvandudzwa kwehammering.Kunyanya, nyundo dzekuboora mabheti anoshandiswa kuchera sando mumatombo nekongiri anogona kusungirirwa kune yakazara shank uye chuck system yakagadzirirwa chinangwa ichi.Iyo SDS inokurumidza kuburitsa sisitimu ndiyo yakajairwa yekunamatira nzira yemazuva ano sando drill bits.Haisi chete inopa nzira inokurumidza, iri nyore uye yakachengeteka yekurovera dhiri, zvakare inova nechokwadi chekufambisa kwesimba kune iyo drill bit pachayo.

SDS-Max - shanu gomba rakatenderera mubato

SDS-Plus zvakare ine painogumira.Kazhinji, dhayamita yekubata yeSDS Plus i10mm, saka kuchera maburi madiki uye epakati harisi dambudziko.Pakuchera makomba mahombe kana akadzika, torque isina kukwana inogona kuita kuti chibooreso chibatire uye mubato utyoke panguva yekushanda.BOSCH yakagadzira SDS-MAX yakavakirwa paSDS-Plus, ine grooves matatu nemakomba maviri.Mubato weSDS Max une mikoto mishanu.Kune matatu akavhurika slots uye maviri akavharwa slots (kudzivirira iyo drill bit kubva pakubhururuka kunze).Inonyanya kuzivikanwa semigero mitatu uye maviri makomba akatenderedza mubato, anozivikanwawo semakomba mashanu akatenderedza mubato.Iyo SDS Max mubato ine dhayamita ye18 mm uye inokodzera zvirinani kune rinorema-basa basa kupfuura SDS-Plus mubato.Naizvozvo, iyo SDS Max mubato une torque yakasimba kupfuura iyo SDS-Plus uye yakakodzera kushandisa yakakura dhayamita inokanganisa dhiri mabhiti emabasa makuru uye akadzika gomba.Vanhu vazhinji vakambotenda kuti iyo SDS Max system yaizotsiva yekare SDS system.Muchokwadi, iyo huru yekuvandudza kune sisitimu ndeyekuti piston ine sitiroko yakareba, saka kana ichirova chibooreso, mhedzisiro yacho yakasimba uye dhiri rinocheka zvakanyanya.Kunyangwe kukwidziridzwa kuhurongwa hweSDS, iyo SDS-Plus system icharamba ichishandiswa.Iyo SDS-MAX's 18mm shank dhayamita inoguma nemitengo yakakwira kana uchigadzira madiki ekudhirowa.Izvo hazvigone kunzi inotsiva SDS-Plus, asi zviri nani mubatsiri.Sando dzemagetsi uye drills zvinoshandiswa zvakasiyana kune dzimwe nyika.Kune akasiyana marudzi emubato uye maturusi emagetsi ehuremu hwesando dzakasiyana uye masaizi ekudhirowa.

Zvichienderana nemusika, SDS-plus ndiyo yakajairika uye inogaro gara mabhiti ekuboora kubva pa4 mm kusvika 30 mm (5/32 in. kusvika 1-1/4 mukati.).Hurefu hwakazara 110mm, kureba kwepamusoro 1500mm.SDS-MAX inowanzo shandiswa kumakomba akakura uye mapikicha.Impact drill bits anowanzo pakati pe1/2 inch (13 mm) uye 1-3/4 inch (44 mm).Hurefu hwese hunowanzo 12 kusvika 21 inches (300 kusvika 530 mm).
