Kodi Kusiyanitsa Pakati pa SDS ndi HSS Drill Bits ndi Chiyani?

Pali masukulu awiri oganiza kuti SDS imayimira chiyani - mwina ndi slotted drive system, kapena imachokera ku German 'stecken - drehen - sichern' - kutanthauziridwa kuti 'insert - twist - safe'.

Chilichonse chomwe chili cholondola - ndipo chikhoza kukhala zonse ziwiri, SDS imatanthawuza momwe kubowola kumalumikizidwa ndi kubowola. Ndilo liwu lomwe limagwiritsidwa ntchito pofotokoza shank ya kubowola - shank imatanthawuza gawo la kubowola lomwe limatetezedwa ku chipangizo chanu. Pali mitundu inayi ya zobowola za SDS zomwe tifotokoza mwatsatanetsatane pambuyo pake.

HSS imayimira chitsulo chothamanga kwambiri, chomwe ndi zinthu zomwe zimagwiritsidwa ntchito pobowola. Zobowola za HSS zilinso ndi mawonekedwe anayi osiyana siyana - owongoka, ochepetsedwa, opendekera, ndi taper ya morse.

KUSIYANA KODI PAKATI PA HDD NDI SDS?
Kusiyana pakati pa ma HSS ndi ma SDS kubowola kumatanthawuza momwe kubowola kumamangidwira kapena kukakamira mkati mwa kubowola.

Zobowola za HSS zimagwirizana ndi chuck iliyonse. Kubowola kwa HSS kumakhala ndi shank yozungulira yomwe imalowetsedwa m'bowolo ndipo imasungidwa m'malo mwake ndi nsagwada zitatu zomwe zimamanga mozungulira shank.

Ubwino wa ma HSS drill bits ndikuti amapezeka kwambiri ndipo amatha kugwiritsidwa ntchito m'mitundu yambiri. Choyipa chachikulu ndichakuti chobowolacho chimakhala chomasuka. Mukamagwiritsa ntchito, kugwedezeka kumamasula chuck kutanthauza kuti wogwiritsa ntchitoyo ayenera kuyimitsa kaye ndikuyang'ana kumangirira, zomwe zingakhudze nthawi yomaliza ntchito.

Kubowola kwa SDS sikuyenera kumangidwa. Itha kuyikidwa mophweka komanso momasuka mumipata ya SDS hammer drill. Pogwiritsa ntchito, kagawo kakang'ono kamateteza ku kugwedezeka kulikonse kuti asunge kukhulupirika kwa kukonza.

KODI ZINTHU ZOFUNIKA KWAMBIRI ZA SDS DRILL BITS ndi ziti?
Mitundu yodziwika kwambiri ya SDS ndi:

SDS - SDS yoyambirira yokhala ndi zingwe zotsekera.
SDS-Plus - yosinthika ndi mabowo okhazikika a SDS, ndikupereka kulumikizana kosavuta. Ili ndi zingwe za 10 mm zokhala ndi mipata inayi yomwe imagwira motetezeka kwambiri.
SDS-MAX - SDS Max ili ndi shank yayikulu 18mm yokhala ndi mipata isanu yomwe imagwiritsidwa ntchito pamabowo akulu. Sizosinthana ndi kubowola kwa SDS ndi SDS PLUS.
Spline - Ili ndi shank yokulirapo ya 19mm ndi splines yomwe imagwira zolimba.
Zida za Rennie zili ndi zida zonse za SDS zobowola zomwe zimapereka magwiridwe antchito apamwamba. Mwachitsanzo, zida zake zobowola nyundo za SDS Pus zimapangidwa pogwiritsa ntchito nsonga yolimba yolimbana ndi kugunda yopangidwa ndi sintered carbide. Ndi abwino kubowola konkire, blockwork, miyala yachilengedwe, ndi njerwa zolimba kapena zobowoleza. Kugwiritsa ntchito ndikofulumira komanso kosavuta - shank imalowa mu chuck yosavuta yodzaza masika popanda chifukwa chomangirira, kulola kuti isunthike mmbuyo ndi mtsogolo ngati pisitoni pakubowola. Gawo losazungulira la shank limalepheretsa kubowola kuti zisazungulire panthawi yogwira ntchito. Nyundo yakubowola imathandizira kuthamangitsa pobowola yokha, osati kuchuluka kwa chuck, kupangitsa kuti SDS shank katsabola ikhale yopindulitsa kwambiri kuposa mitundu ina ya shank.

SDS Max Hammer Drill bit ndi chobowolera nyundo cholimba kwambiri, chopatsa chimodzi mwazinthu zabwino kwambiri zomwe zimapezeka pamsika. Chobowolacho chamalizidwa ndi nsonga yamtanda ya tungsten carbide kuti ikhale yolondola komanso yamphamvu. Chifukwa chobowola cha SDSchi chimangokwanira m'makina obowola okhala ndi SDS max chuck, ndibowola mwapadera pantchito yolemetsa pa granite, konkriti, ndi miyala.

NTCHITO ZABWINO KWA HSS DRILL BITS
Ma HSS Drill Bits amatha kusinthana pamagwiritsidwe osiyanasiyana. Kupititsa patsogolo ntchito ndi khalidwe zimatheka kupyolera mwa kuwonjezera kwa mankhwala osiyanasiyana kuti apereke ntchito yabwino. Mwachitsanzo, Rennie Tools HSS Cobalt Jobber Drill Bits amapangidwa kuchokera ku M35 alloyed HSS chitsulo chokhala ndi 5% Cobalt, zomwe zimawapangitsa kukhala olimba komanso osamva kuvala. Amapereka mayamwidwe odabwitsa ndipo amatha kugwiritsidwa ntchito pazida zamagetsi zam'manja.

Zina za HSS Jobber Drills zamalizidwa ndi wosanjikiza wakuda wa oxide chifukwa cha kutentha kwa nthunzi. Izi zimathandiza kuthetsa kutentha, ndi kutuluka kwa chip ndikupereka malo ozizira pamwamba pa kubowola. Kubowola kwa HSS tsiku lililonse kumapereka magwiridwe antchito apamwamba kwambiri pamitengo, zitsulo, ndi pulasitiki.
