Ibanga lokusebenza lama-bolts asetshenziselwa uxhumano lwesakhiwo sensimbi ngu-3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 njalonjalo. Amabhawodi ebanga lesi-8.8 nangaphezulu enziwe ngensimbi ephansi ye-carbon alloy noma insimbi ye-carbon ephakathi futhi afakwe ukushisa (acinywe, aqinile), ngokuvamile abizwa ngokuthi ama-bolts anamandla aphezulu kanti amanye ngokuvamile abizwa ngokuthi ama-bolt ajwayelekile.Intambo enembayo ephezulu iyisihluthulelo sokwenzaizinga okusezingeni eliphezulu CNC machining izingxenye.
Ilebula yebanga lokusebenza yebhawudi yakhiwe izingxenye ezimbili, ngokulandelanayo ezimele inani lamandla aqinile okuzisholo kanye nesilinganiso sokubhinca sento yebhawodi. Njenge:
Ngamabhawodi ekilasi lokusebenza 4.6, incazelo ithi:
Amandla okuzisholo okuqinile wento yebhawodi afika ku-400MPa;
Isilinganiso samandla we-bolt material ngu-0.6;
Amandla okuvunwa okuzisholo okwenziwa kwebhawodi ngu-400×0.6=240MPa.
Ibanga lokusebenza 10.9 high amandla bolt, impahla yayo ngemva kokwelashwa ukushisa, ingafinyelela:
Amandla okuzisholo okuqinile wento yebhawodi afinyelela ku-1000MPa;
Isilinganiso samandla we-bolt material ngu-0.9;
Amandla okukhiqiza ajwayelekile wento yebhawodi ngu-1000×0.9=900MPa.
Incazelo yebanga lokusebenza kwebholithi iyindinganiso yamazwe ngamazwe. Amabhawudi webanga elifanayo lokusebenza, kungakhathaliseki umehluko phakathi kwezinto zawo kanye nemvelaphi, anokusebenza okufanayo, futhi izinga lokusebenza kuphela elingakhethwa edizayini.
Amabanga wamandla 8.8 kanye no-10.9 abhekisela emazingeni okumelana nokucindezeleka kwe-shear ama-bolts 8.8GPa kanye no-10.9GPa
8.8 Amandla okubamba amandla 800N/MM2 okuzisholo okukhiqiza amandla 640N/MM2
Ngokuvamile, “x. I-Y” isetshenziselwa ukukhombisa amandla ebhawodi, X*100= amandla aqinile ebhawodi, X*100* (Y/10) = amandla okukhiqiza ebhawodi (ngoba ngokwelebula: khipha amandla/ukuqina amandla =Y/10)
Njengo-4.8, amandla aqinile webhawodi: 400MPa; Amandla okukhiqiza angu-400*8/10=320MPa.
Ngaphezu kwalokho: amabhawodi ensimbi engagqwali ngokuvamile abhalwe ngokuthi A4-70, A2-70, incazelo yenye incazelo.
Ukukala i
Iyunithi yokulinganisa ubude emhlabeni namuhla kunezinhlobo ezimbili eziyinhloko, eyodwa yohlelo lwemethrikhi, iyunithi yokulinganisa imitha (m), amasentimitha (cm), amamilimitha (mm), njll., eYurophu, eChina naseJapane nakwamanye aseningizimu-mpumalanga. Ukusetshenziswa kwe-Asia kungaphezulu, enye isiNgisi, iyunithi yokulinganisa ikakhulukazi ngamasentimitha (intshi), elilingana nedolobha elidala "ezweni lakithi, lisetshenziswa kabanzi e-United States, eBrithani nakwamanye amazwe aseYurophu naseMelika.
Isilinganiso semethrikhi: (isisekelo esingu-10) 1m =100 cm=1000 mm
I-Imperial system: (isisekelo 8) 1 intshi =8 imizuzu iyintshi engu-1 =25.4 mm 3/8 x 25.4 =9.52
Imikhiqizo engaphansi kuka-1/4 isebenzisa inombolo yokuqokwa ukuze imele usayizi wekheli layo, njengokuthi: 4#, 5#, 6#, 7#, 8#, 10#, 12#
Intambo yesikulufu
Umucu umumo onemigqa ezungezayo efanayo engxenyeni yendawo engaphandle noma engaphakathi yento eqinile. Ngokwezici zayo zesakhiwo kanye nokusetshenziswa kungahlukaniswa izigaba ezintathu:
Intambo evamile: umumo wezinyo elingunxantathu, osetshenziselwa ukuhlanganisa noma ukubopha izingxenye. Intambo evamile ihlukaniswe yaba izinhlobo ezimbili zentambo eqinile kanye nentambo ecolekile ngokuya ngephitshi, futhi intambo ecolekile inamandla okuxhumana aphezulu.
Intambo yokudlulisa: i-trapezoid yezinyo, unxande, isaha nonxantathu, njll.
Intambo yophawu: Isetshenziselwa ukuxhuma uphawu, ikakhulukazi intambo yepayipi, intambo ye-taper kanye nentambo yepayipi ye-taper.
Ukuhlukaniswa ngokomumo:
Ibanga elilingana nentambo
Imicu yokunemba okuphezulu iyingxenye ebalulekile yokwenzaizinga okusezingeni eliphezulu CNC Machining izingxenye.
Ukulingana inani lokuxega noma ukucinana phakathi kwentambo yesikulufu, futhi ibanga elilinganayo liyinhlanganisela ecacisiwe yokuchezuka nokubekezelelana okusebenza ochungechungeni lwangaphakathi nolwangaphandle.
1. Ngentambo eyi-intshi efanayo, kunamabanga amathathu entambo yangaphandle: 1A, 2A kanye no-3A, kanye namabanga amathathu entambo yangaphakathi: 1B, 2B kanye no-3B, wonke alingana negebe. Lapho inombolo yerenki iphakeme, ilingana kakhulu. Ku-inch THREADS, ukuchezuka kucaciswe kuphela kumabanga 1A no-2A, ukuchezuka kwebanga 3A kunguziro, kanti ukuchezuka kwebanga kwebanga 1A no-2A kuyalingana. Uma likhulu inani lamabanga, kuncane ukubekezelelana.
I-Class 1A ne-1B, amamaki okubekezelela axege kakhulu, afanele ukubekezelela ukulingana kwemicu yangaphakathi neyangaphandle.
Amakilasi 2A kanye no-2B amakilasi avame kakhulu okubekezelela intambo amiselwe uchungechunge lwama-British lwezixhumi zokubopha.
I-Class 3A ne-3B, isikulufu ukuze senze ukulingana okuqinile, ezifanele izibophelelo ezinokubekezelela okuqinile, ngedizayini ebalulekile yokuphepha.
Ochungechungeni lwangaphandle, i-CLASS 1A ne-2A inokubekezelela okufanele, i-CLASS 3A ayinakho. Ukubekezelelana kwe-Class 1A kukhulu ngo-50% kunokubekezelelana kweklasi 2A, 75% kukhulu kunokubekezelelana kwekilasi 3A, emicu yangaphakathi, ukubekezelelana kwekilasi 2B kukhulu ngo-30% kunokubekezelelana kwe-2A. Ikilasi 1B likhulu ngo-50% kunekilasi 2B futhi likhulu ngo-75% kunekilasi 3B.
2. Intambo yemethrikhi, intambo yangaphandle inamabanga amathathu entambo: 4h, 6h no-6g, intambo yangaphakathi inamabanga amathathu entambo: 5H, 6H, 7H. (Amabanga anembayo ochungechunge lwansuku zonke athi I, II, III, futhi ngokuvamile II.) Kuchungechunge lwemethrikhi, ukuchezuka okuyisisekelo kuka-H kanye no-h kunguziro. Ukuchezuka okuyisisekelo kuka-G kuhle, futhi ukuchezuka okuyisisekelo kuka-E, F kanye no-G kunegethivu.
H indawo evamile yokubekezelela indawo yomucu wangaphakathi, ngokuvamile ayisetshenziswa njengendawo yokunameka ngaphezulu, noma ngongqimba oluncane lwe-phosphating. G ukuchezuka okuyisisekelo kwezikhathi ezikhethekile, njengokujiya, ngokuvamile okungavamile ukusetshenziswa.
g ijwayele ukusetshenziselwa ukunamathelisa okungu-6-9um okuncanyana, uma izidingo zomdwebo womkhiqizo zingamabhawudi angu-6h, intambo yesikulufu ngaphambi kokucwecwa ithatha ibhendi yokubekezelela engu-6g.
Inhlanganisela engcono kakhulu yochungechunge ilingana no-H/g, H/h noma G/h, kumabhawodi, amantongomane neminye imicu yokubopha ecolisisiwe, ukulingana okujwayelekile okunconyiwe okungu-6H/6g.
3. Ukumaka intambo
Imingcele eyinhloko yejiyomethri yezintambo zokuzibamba kanye nokuzimba
1. Idayamitha enkulu/idayamitha yangaphandle (d1) : ububanzi besilinda esicatshangelwayo esinemiqhele enentambo egqagqene. Idayamitha yentambo ngokuyisisekelo imele ububanzi bokulinganisa bosayizi wentambo.
2. Indlela yezinyawo/ububanzi obungezansi (d2) : ububanzi besilinda esicatshangelwayo lapho okungaphansi kwentambo kugqagqana khona.
3. Isikhala samazinyo (p) : kubhekisela ebangeni le-axial phakathi kwamaphoyinti amabili ahambisanayo amazinyo ancikene emgqeni ophakathi. Ohlelweni lombuso, ibanga phakathi kwamazinyo liboniswa inani lamazinyo ngamasentimitha angu-25.4.
Okulandelayo kuklelisa izicaciso ezijwayelekile zebanga lamazinyo (imethrikhi) Inombolo yamazinyo (intshi)
