Momwe Mungasankhire Zida za Rock Drill

Khwerero 1: Dziwani Kusintha kwa Shank pa Drill Yanu.

Gawo loyamba posankha choyenerazitsulo ndi bitspakubowola kwamwala ndi kugwiritsa ntchito kwanu kungakhale kudziwa kasinthidwe ka shank pakubowola kwanu.

Pali mitundu itatu yokha ya shank. 7/8 x 3 ¼”, 7/8 x 4 ¼” ndi 1 x 4 ¼”. Miyezo iyi imatanthawuza kukula kwa chitsulo cha hex (chopimwa modutsa ma flats) ndi kutalika pamwamba pa kolala yosungira. Zobowola zazikuluzikulu zimayendetsa chitsulo chokulirapo koma sizachilendo kukhala ndi 55lb kubowola komwe kumapangidwira shank 7/8 x 3 ¼”. Muyenera kudziwa kasinthidwe ka shank omwe muli nawo musanayambe kuyitanitsa chitsulo chobowola.

Khwerero 2: Dziwani Kubowola ndi Kusintha kwa Bit kwa Rock Drill Shank Yanu

H Chitsulo ndi Bits:

Ulusi wa H mwina ndiye ulusi womwe umagwiritsidwa ntchito kwambiri ndi makontrakitala chifukwa cha kusinthasintha kwake komanso kupezeka kwake. Ulusi wamphongo pazitsulo ndi pafupifupi 1 "diameter ndi pafupifupi 3/4" yaitali. Chitsulocho nthawi zambiri chimakhala ndi 12 "mpaka 120" kutalika mumitundu yonse itatu ya shank. Tizigawo tating'onoting'ono timachokera ku 1 3/8 "mpaka 3" m'mimba mwake mumtanda wa carbide (odziwika kwambiri), 1 3/8 "mpaka 2" pamtanda wozama wa carbide, 1 3/8" mpaka 2 1/4" mu batani ma bits ndi 1 3/8 "mpaka 2 -5/8" m'mimba mwake muzitsulo zonse.

H ulusi kubowola zitsulo nthawi zambiri amapangidwa kuchokera mkulu carbon zitsulo. Nthawi zambiri imakhala yopangidwa mwachinyengo, yopangidwa ndi makina, ndi kutentha kuti ikhale ndi kunja kwa chitsulo chosagwira ntchito kwinaku ndikusunga pachimake chofewa pang'ono kuti chigwire ndikusamutsa mphamvu. Ndizitsulo zoyendetsa pamapewa zomwe zikutanthauza kuti siketi ya pang'onopang'ono imamangiriza mpaka pamapewa opangidwa / opangidwa pazitsulo. Mphamvu ya percussive imasamutsidwa ngakhale chitsulo ndi siketi ya pang'onopang'ono kumaso - kuphwanya zinthu zomwe zili patsogolo pake.

Ngakhale ulusi wa H ulusi ndiye ulusi wodziwika bwino wa makontrakitala - umakhala ndi zofooka zake. Kuyendetsa pamapewa kumapangitsa kuti pang'onopang'ono ikhale yolimba pamapewa achitsulo. Ngati imamasuka pamapewa - mphamvu zonse zobowola zikuyenda ulusi wochepa kwambiri pazitsulo ndi zitsulo - ndipo zidzalephera mwamsanga. Pitirizani kupanikizika kosalekeza ndipo musalole kuti kubowola kugwedezeke mu dzenje ndipo ulusi wa H uyenera kugwira ntchito bwino pobowola miyala yolimba kwambiri.

Mitundu Yonse ya Carbide Cross:

Kachidutswa kakang'ono kameneka kali ndi zoyikapo 4 zazikulu za silver brazed carbide zomwe zimagwira bwino ntchito pobowola miyala yolimba. Amagwirizira bwino geji ndipo amatha kunoledwa ngati atopa kwambiri kuti asagwire ntchito.

Shallow Carbide Cross Bits:

Chuma chimawononga ndalama zocheperako kuposa Full Carbide bit koma chimakhala ndi kachigawo kakang'ono ka tungsten carbide. Nthawi zina amatha kukhala "zachuma" nthawi zina. (ntchito zazing'ono, zowononga kwambiri, kubowola m'malo omwe nthawi zambiri amalephera)

Mabatani a Carbide:

Batanilo limawononga ndalama zochulukirapo kuposa mtanda wa Full Carbide. Ili ndi mabatani angapo a carbide omwe amapanikizidwa kumaso kwa pang'ono. Kubowola pamanja kwakukulu kumatha kupereka mphamvu zokwanira kuti zipangitse kuti tizidutswa tating'ono tating'ono ting'onoting'ono ting'onoting'ono ta liwiro ndi moyo wautali m'malo oyenera.

Zida Zonse Zachitsulo:

Izi zopingasa zimapangika ndikuwumitsidwa ndipo ndi zosankha zotsika mtengo. Popanda gawo la carbide mutha kuyembekezera moyo waufupi makamaka m'mikhalidwe ya abrasive.

Taper Drill Steel:

Chitsulo chobowola chopangidwa ndi tapered chinali/ chimagwiritsidwa ntchito makamaka pokumba pansi pa nthaka pobowola jackleg. 12 digiri taper ndiyofala kwambiri ku Canada ndipo digiri ya 11 ndiyofala kwambiri ku US ndi Central America. Chovala chachikazi chimakankhira kuchitsulo chobowola chachimuna. Zikakwerana - zimatha kulekanitsidwa ndi kugogoda pang'ono pomwe nthitiyo yatha.

Ena makontrakitala atengera izo - monga Steel imapangidwa m'mavoliyumu akuluakulu ndipo ndiyosavuta kupanga motero imatha kukhala yotsika mtengo. Komabe, idapangidwira kupanga migodi ndipo ili ndi malire. Kubowola zitsulo zokhazikika za shank ndi 7/8 x 4 ¼ ndipo mitundu ya ma bits ndi yochepa. Kulephera kukhalabe ndi mphamvu yotsika kungayambitse kutaya pang'ono mu dzenje.

Zitsulo zachitsulo ndi zingwe:

Zingwe 100 (1” chingwe, R25) ndi chingwe 125 (chingwe 1 ¼”, R32) zimagwiritsidwa ntchito kwambiri popanga migodi mobisa. Makontrakitala ambiri atembenukira ku chitsulo chamtunduwu kuti apereke moyo wautali, makamaka m'malo ovuta kwambiri kapena pobowola mabowo 2 ½ ” kuphatikiza awiri. Chitsulo chobowola nthawi zambiri chimapangidwa ndi carburized chomwe ndi njira yothira chitsulo ndi zinthu za carbon mu ng'anjo. Izi zimapangitsa chitsulo kukhala cholimba kwambiri ndikusunga kulimba kocheperako kuti kusamutse shockwave. Ulusiwo ndi waukulu/utali ndipo umakhala pansi mkati mwa thanthwe. Kuphatikiza uku kumakhululukira kwambiri pobowola zovuta. Crowder Supply imapanga mitundu yambiri yazitsulo ndi ma adapter pang'ono pobowola njanji zazikulu koma sikofunikira kupitilira ulusi uwiriwu ndi kubowola pamanja.

Zitsulo za ulusi wa zingwe zimakupatsaninso mwayi woyendetsa zingwe zobowola pogwiritsa ntchito zitsulo zowonjezera. Izi zimakupatsani mwayi woboola dzenje lakuya kapena kuboola zazitali m'malo otsekeredwa.
