Ho Utloisisa-Liphoso Tsa ho Rata Screw: Masosa, Thibelo, le Tataiso e Nepahetseng ea RPM
Likurufu-li etselitsoe ho phunya, ho tlanya le ho tiisa tšebetsong e le 'ngoe. Leha ho le joalo, ho kenya ka mokhoa o sa lokelang ho ka baka tšenyo ea pele ho nako ea ho cheka le ho hloleha ho tiisa. Ka tlaase mona ho na le tlhaloso ea mefuta e tloaelehileng ea ho hlōleha e hlokometsoeng tšimong, lisosa tsa tsona, le mokhoa oa ho li thibela.
1. Likoluoa li Chepiloe
Taba e Shebetsoeng:
Likoluoa tse sehang sebakeng sa ho phunya li bonahala li robehile kapa li robehile pele li kenella ka botlalo.
Mabaka a mantlha:
Matla a axial a feteletseng nakong ea ho khanna
Ho qobella screw pele ntlha ea ho cheka e qala ho seha
Meroalo ea ts'ebetso ea tšohanyetso e tsoang ho bakhanni ba sa tsitsang
Malebela a Thibelo:
Lumella ntlha ea ho cheka hore e sehe ka tlhaho pele khatello e eketseha
Sebelisa matla a tsitsitseng, ho e-na le ho sututsa ka mokhoa o tsitsitseng-
Etsa bonnete ba hore karolo ea mokhanni e tsamaisana le perpendicular ho ea holimo
2. Ha ho Lesoba le Phatiloeng
Taba e Shebetsoeng:
Sekoti se bilika ntle le ho phunyeletsa bokaholimo ba tšepe.
Mabaka a mantlha:
Ho thatafala ha lintho tsa motheo ho feta bokhoni ba ho cheka
Mokhanni o ile a khutlela morao ka phoso
Sebaka sa ho cheka se boreleli kapa se senyehileng se bakoang ke ho ts'oaroa kapa liphoso tsa tlhahiso
Malebela a Thibelo:
Netefatsa botenya ba tšepe le matla a thata pele o kenya
Sheba tsela ea ho potoloha ha mokhanni pele u khanna
Hlahloba libaka tsa ho cheka hore na ho na le tšenyo efe pele u e sebelisa
3. Flute e Qhibilihile
Taba e Shebetsoeng:
Likolutu tsa ho phunya li bontša matšoao a ho chesa haholo le ho senyeha.
Mabaka a mantlha:
RPM e phahameng haholo
Nako e telele ea ho cheka li-substrates tse thata
Mocheso o hahelletsoeng ntle le ho tlosoa ka nepo
Malebela a Thibelo:
Fokotsa RPM ha u cheka tšepe e teteaneng kapa e thata ho feta
Sebelisa khatello e tsitsitseng ho khutsufatsa nako ea ho cheka
Qoba "hover drilling" e hlahisang mocheso ntle le ho khaola
4. Meltd Drill Point
Taba e Shebetsoeng:
Ntlha e fetoha e chitja kapa ea chesoa, e lahleheloa ke bokhoni ba ho itšeha.
Mabaka a mantlha:
Matla a feteletseng a kopantsoeng le lisebelisoa tse thata
Khohlano e phahameng e bakoang ke RPM e fosahetseng
Ho senya mocheso o fokolang nakong ea ho cheka
Malebela a Thibelo:
Bapisa RPM le botenya ba tšepe
Qoba matla a feteletseng a theohelang tlaase
Lumella jiometry ea boro e etse mosebetsi
5. Drill Bit Split
Taba e Shebetsoeng:
Sebaka sa ho phunya se phunyeha kapa se petsoha haufi le setsi.
Mabaka a mantlha:
Matla a feteletseng a sebelisoang nakong ea ho khanna
Ho hanyetsa ka tshohanyetso ha o phunyeletsa tshepe e teteaneng
Li-spikes tsa torque ea bakhanni
Malebela a Thibelo:
Boloka khatello e tsitsitseng nakong eohle ea ho cheka
Qoba ho phahama ha torque ka tšohanyetso
Sebelisa likurufu tse etselitsoeng botenya ba tšepe e shebiloeng
Tataiso e khothalelitsoeng ea RPM bakeng sa Boithati{0}
Khetho e nepahetseng ea RPM e bohlokoa bakeng sa ho thibela ho chesa le ho senya ho cheka. Mekhahlelo e latelang ke litataiso tse akaretsang tsa indasteri:
| Botenya ba Tšepe | RPM e khothalelitsoeng |
|---|---|
| Ka tlase ho kapa ho lekana le 1.5 mm | 2500-3000 RPM |
| 1.6–3.0 limilimithara | 1800-2500 RPM |
| 3.1–6.0 limilimithara | 1200-1800 RPM |
| E kholo ho feta kapa e lekana le 6.0 mm | 800-1200 RPM |
Ntlha ea bohlokoa:
RPM e phahameng ha e bolele ho cheka kapele. Lebelo le feteletseng hangata le baka mocheso o mongata, lintlha tse qhibilihisitsoeng, le ho fokotsa bophelo ba lisebelisoa.
Qetello
Bongata bo hlolehileng- ho cheka screw screwts'ebeliso-e amanang le sehlahisoa{1}e amanang. Ka ho laola RPM, ho sebelisa matla a axial a nepahetseng, le ho bapisa moralo oa screw ho boima ba lintho tse bonahalang, li-installer li ka fokotsa tšenyo ea li-drill point haholo le ho ntlafatsa ts'ebetso ea ho tiisa.
Bakeng sa borakonteraka, barekisi le basebelisi ba indasteri, ho utloisisa mekhoa ena ea ho hloleha hoa thusaho fokotsa litšenyehelo tsa ho kenya, ho fokotsa nako ea ho phomola, le ho atolosa tshebetso ea fasteners. Mekhoa e nepahetseng ea ho kenya e se e nkoa e le karolo ea bohlokoa ea boenjiniere ba sejoale-joale ba fastening.
