Ngati kubowola kwachitsulo chothamanga kwambiri ndi microcosm ya chitukuko cha mafakitale padziko lonse lapansi, ndiye kuti chobowola nyundo yamagetsi chikhoza kuwonedwa ngati mbiri yaulemerero ya zomangamanga zamakono.
Mu 1914, FEIN inapanga nyundo yoyamba ya pneumatic, mu 1932, Bosch anapanga dongosolo loyamba lamagetsi la SDS, ndipo mu 1975, Bosch ndi Hilti pamodzi anapanga dongosolo la SDS-Plus.Zobowola nyundo zamagetsi nthawi zonse zakhala chimodzi mwazinthu zofunika kwambiri pakumanga ndi kukonza nyumba.
Chifukwa chobowola nyundo yamagetsi chimapanga kusuntha kofulumira (kukhudzidwa pafupipafupi) motsatira njira ya ndodo yobowola magetsi pozungulira, sikufuna mphamvu zambiri zamanja kuti kubowola mabowo muzinthu zosasunthika monga konkire ya simenti ndi miyala.
Pofuna kupewa kubowola kuti zisatuluke mu chuck kapena kuwuluka panthawi yozungulira, shank yozungulira imapangidwa ndi ma dimples awiri.Chifukwa cha ma grooves awiri pabowola, kumenyetsa kothamanga kumatha kufulumizitsa komanso kugwirira ntchito bwino kumatha kuwongolera.Chifukwa chake, kubowola nyundo ndi ma SDS shank drill bits ndikothandiza kwambiri kuposa mitundu ina ya shank.Dongosolo lathunthu la shank ndi chuck lomwe limapangidwira izi ndiloyenera kwambiri pobowola nyundo pobowola mabowo pamiyala ndi konkriti.
Dongosolo lotulutsa mwachangu la SDS ndiye njira yolumikizira yolumikizira nyundo yamagetsi masiku ano.Imawonetsetsa kufalikira kwamphamvu kwamagetsi obowola yokha ndipo imapereka njira yachangu, yosavuta komanso yotetezeka yotsekera pobowola.
Ubwino wa SDS Plus ndikuti kubowola kumatha kukankhidwira mu chuck yamasika popanda kumangitsa.Sizikhazikika, koma zimatha kutsetsereka ngati pisitoni.
Komabe, SDS-Plus ilinso ndi malire.Kutalika kwa shank ya SDS-Plus ndi 10mm.Palibe vuto pobowola mabowo ang'onoang'ono ndi ang'onoang'ono, koma mukakumana ndi mabowo akulu ndi akuya, padzakhala torque yosakwanira, zomwe zimapangitsa kuti pobowolawo atsekeredwe panthawi yantchito ndipo shank imasweka.
Chifukwa chake kutengera SDS-Plus, BOSCH idapanganso mipata itatu ndi mipata iwiri ya SDS-MAX kachiwiri.Pali ma groove asanu pa chogwirizira cha SDS Max: atatu ndi ma groove otseguka ndipo awiri ndi ma groove otsekedwa (kuteteza chobowolacho kuti chisawuluke kuchokera mu chuck), zomwe timakonda kuzitcha chogwirira chozungulira cha mipata itatu ndi mipata iwiri, amatchedwanso chogwirira chozungulira cha mipata isanu.Kutalika kwa shaft kumafika 18mm.Poyerekeza ndi SDS-Plus, mapangidwe a chogwirira cha SDS Max ndi oyenera kwambiri pazochitika zolemetsa, kotero kuti torque ya chogwirira cha SDS Max ndi yamphamvu kuposa ya SDS-Plus, yomwe ili yoyenera kubowola nyundo zazikulu zazikulu. ndi ntchito dzenje lakuya.
Anthu ambiri ankaganiza kuti dongosolo la SDS Max linapangidwa kuti lilowe m'malo mwa SDS yakale.Ndipotu, kusintha kwakukulu kwa kachitidwe kameneka ndiko kupatsa pistoni chiwombankhanga chachikulu, kotero kuti pistoni ikagunda pobowola, mphamvu yake imakhala yaikulu ndipo chobowola chimadulidwa bwino.Ngakhale ndikukweza pamakina a SDS, dongosolo la SDS-Plus silidzachotsedwa.Kubowola kwa 18mm kwa SDS-MAX kudzakhala kokwera mtengo kwambiri pokonza tinthu tating'onoting'ono tobowola.Sizinganenedwe kukhala cholowa m'malo mwa SDS-Plus, koma chowonjezera pamaziko awa.
SDS-plus ndiyomwe imapezeka kwambiri pamsika ndipo nthawi zambiri imakhala yoyenera kubowola nyundo yokhala ndi mainchesi 4 mpaka 30mm (5/32 inchi mpaka 1-1/4 inchi), kutalika kwaufupi kwambiri kumakhala pafupifupi 110mm, ndipo Kutalika kwambiri nthawi zambiri sikuposa 1500mm.
SDS-MAX nthawi zambiri imagwiritsidwa ntchito popanga mabowo akulu ndi zosankha zamagetsi.Kubowola nyundo nthawi zambiri kumakhala 1/2 inchi (13mm) mpaka 1-3/4 inchi (44mm), ndipo kutalika kwake nthawi zambiri kumakhala mainchesi 12 mpaka 21 (300 mpaka 530mm).
Gawo 2: Ndodo yoboola
Mtundu wamba
Ndodo yobowola nthawi zambiri imapangidwa ndi chitsulo cha kaboni, kapena chitsulo cha aloyi 40Cr, 42CrMo, ndi zina zambiri. Zobowola nyundo zambiri pamsika zimatengera mawonekedwe ozungulira ngati chobowola chopindika.Mtundu wa groove poyamba udapangidwa kuti uchotse mosavuta chip.
Pambuyo pake, anthu adapeza kuti mitundu yosiyanasiyana ya groove singowonjezera kuchotsedwa kwa chip, komanso kukulitsa moyo wa kubowola.Mwachitsanzo, zobowola pawiri-pawiri zimakhala ndi chochotsa chip mu poyambira.Pochotsa tchipisi, amathanso kuchotsa zinyalala zachiwiri, kuteteza thupi lobowola, kukonza bwino, kuchepetsa kutentha kwamutu, ndikukulitsa moyo wabowola.
Mtundu woyamwa wopanda ulusi
M'mayiko otukuka monga ku Ulaya ndi United States, kugwiritsa ntchito makina opangira mphamvu ndi malo ogwirira ntchito omwe ali ndi fumbi komanso mafakitale omwe ali ndi chiopsezo chachikulu.Kubowola bwino sicholinga chokhacho.Chinsinsi chake ndikuboola bwino malo omwe alipo komanso kuteteza kupuma kwa ogwira ntchito.Chifukwa chake, pali kufunikira kwa ntchito zopanda fumbi.Pakufunidwa uku, zida zoboola zopanda fumbi zidayamba.
Thupi lonse la kubowola kopanda fumbi lilibe zozungulira.Bowolo limatsegulidwa pobowola, ndipo fumbi lonse lapakati pa dzenje limayamwa ndi chotsukira chotsuka.Komabe, chotsukira chotsuka ndi chubu chimafunikira panthawi ya opareshoni.Ku China, kumene chitetezo chaumwini ndi chitetezo sichigogomezedwa, ogwira ntchito amatseka maso awo ndikupuma kwa mphindi zingapo.Kubowola kopanda fumbi kotereku sikungatheke kukhala ndi msika ku China kwakanthawi kochepa.
GAWO 3: Blade
Tsamba lamutu nthawi zambiri limapangidwa ndi YG6 kapena YG8 kapena carbide ya simenti yapamwamba kwambiri, yomwe imayikidwa pathupi powotcha.Opanga ambiri asinthanso njira yowotcherera kuchokera ku kuwotcherera koyambirira kwamanja kupita ku kuwotcherera basi.
Opanga ena adayambanso kudula, mitu yozizira, kukonza nthawi imodzi, ma gilling grooves, kuwotcherera basi, zonse zomwe zakwanitsa kupanga zokha.Zobowola 7 za Bosch zimagwiritsa ntchito kuwotcherera pakati pa tsamba ndi ndodo yobowola.Apanso, moyo ndi mphamvu ya kubowola pang'ono amabweretsedwa kwa msinkhu watsopano.Zofunikira zanthawi zonse zobowola nyundo zamagetsi zitha kukwaniritsidwa ndi mafakitale ambiri a carbide.Masamba obowola wamba amakhala amtundu umodzi.Pofuna kuthana ndi zovuta zogwira ntchito bwino komanso zolondola, opanga ndi opanga ochulukirachulukira apanga zobowolera m'mbali zambiri, monga "tsamba la mtanda", "tsamba la herringbone", "tsamba lamitundu yambiri", ndi zina zambiri.
Mbiri yachitukuko cha kubowola nyundo ku China
Malo obowola nyundo padziko lonse lapansi ali ku China
Chiganizochi si mbiri yabodza ayi.Ngakhale kubowola nyundo kuli paliponse ku China, pali mafakitale ena obowola nyundo pamwamba pamlingo wina ku Danyang, Jiangsu, Ningbo, Zhejiang, Shaodong, Hunan, Jiangxi ndi malo ena.Eurocut ili ku Danyang ndipo pakadali pano ili ndi antchito 127, ili ndi malo okwana masikweya mita 1,100, ndipo ili ndi zida zambiri zopangira.Kampaniyo ili ndi mphamvu zolimba zasayansi ndiukadaulo, ukadaulo wapamwamba, zida zabwino kwambiri zopangira, komanso kuwongolera bwino kwambiri.Zogulitsa za kampaniyi zimapangidwa motsatira mfundo za Germany ndi America.Zogulitsa zonse ndizabwino kwambiri ndipo zimayamikiridwa kwambiri m'misika yosiyanasiyana padziko lonse lapansi.OEM ndi ODM angaperekedwe.Zogulitsa zathu zazikulu ndi zitsulo, konkire ndi matabwa, monga ma Hss kubowola, ma SDs kubowola, ma Maonry drill bits, wod dhil kubowola, magalasi ndi matailosi kubowola, TcT ma saw, masamba a diamondi, ma oscillating ma saw, bi- macheka azitsulo, macheka a diamondi, macheka a TcT, macheka obowola ndi macheka a Hss, etc. Kuphatikiza apo, tikugwira ntchito mwakhama kuti tipeze mankhwala atsopano kuti tikwaniritse zosowa zosiyanasiyana.
