Yeqela kokuqukethwe
Impendulo esheshayo: Ubukhulu belokha yensimbi buchazwa kangcono ngamamilimitha, hhayi ama-gauge — izinhlelo ze-gauge ziyahlukahluka ngokwezwe nezinto zokwakha, kuyilapho i-mm icacile. Amalokha ekhwalithi akhiwe ngensimbi egoqwe ngokubandayo engu-0.4–1.0 mm: 0.4–0.5 mm yokusetshenziswa kwehhovisi okulula, 0.6 mm njengendinganiso yezikole namahhovisi, 0.8 mm yezindawo ezinabantu abaningi, kanye ne-1.0 mm yokusetshenziswa okunzima. Qinisekisa noma yikuphi ukucaphuna ngesampula elinganiswe nge-caliper noma isitifiketi sensimbi.
Umthengi eNigeria wake wangithumelela ikhotheshini evela kumhlinzeki onikeza amalokha “angama-22 gauge” ngentengo eyayibukeka kahle kakhulu. Wangibuza ukuthi kusho ukuthini ukuthi i-22 gauge ngamamilimitha ukuze ayiqhathanise nesipho sethu esingu-0.6 mm. Ngayiguqula, futhi ilokha lakhe “elishibhile” elingu-22-gauge laliyinsimbi encane kuneyethu ngentengo ephezulu. Akaphindanga wabuza nge-gauge futhi.
Ubukhulu buyinto abathengi abagxila kuyo ngenombolo eyodwa — futhi abahlinzeki benombolo eyodwa bavame ukubuthanda. Nansi indlela yokucabanga ngokujiya kwelokha yensimbi ngokucacile.
Kungani "iGauge" iyisithiyo kubathengi bamazwe ngamazwe
I-Gauge iyisistimu yezinombolo yakudala lapho inombolo ephezulu isho insimbi encane — futhi imephu ihlukile phakathi kwezindinganiso. I-US steel sheet gauge, i-British Standard Wire Gauge, kanye ne-stainless gauge konke kunikeza amanani ahlukene e-millimeter enanini elifanayo. Umhlinzeki ocaphuna “i-18 gauge” ngaphandle kokuqamba indinganiso ucaphuna inombolo engasho ubukhulu obuhlukahlukene obuhlukahlukene.
Ukuguqulwa okungekuhle ngaphansi kwendinganiso evamile yeshidi lensimbi lase-US, ukuze kuqondiswe kuphela:
| Igeyiji (ishidi lensimbi lase-US, cishe) | Ubukhulu |
|---|---|
| I-26 gauge | ≈ 0.45mm |
| I-24 gauge | ≈ 0.6mm |
| I-22 gauge | ≈ 0.75mm |
| I-20 gauge | ≈ 0.9mm |
| I-18 gauge | ≈ 1.2mm |
Qaphela ugibe: ezinye izimakethe zicaphuna ngokunganaki elithi “gauge” zisebenzisa ithebula elihlukile, kanti abanye abahlinzeki basebenzisa leli gama ukuzwakala njengobuchwepheshe ngenkathi bethumela noma ngabe ikhoyili yayiyini. Amamilimitha asusa ngokuphelele ukungaqondakali. Yingakho amathenda aphesheya kwezilwandle, kanye namaphepha ethu okucaphuna, echaza ubukhulu ngamamilimitha - futhi kungani singakukhuthaza ukuthi ubuze noma yimuphi umhlinzeki, noma ngabe yiliphi inombolo ayicaphunayo, “futhi yini leyo ngamamilimitha, esitifiketini somshini?”
Ubukhulu Belokha Lensimbi Ngokwesikesi Sokusetshenziswa
Akukho "ukujiya okujwayelekile" okujwayelekile — kukhona ububanzi bokusebenza, futhi iphuzu elifanele kulo lincike ekutheni ilokha izohlala ini. Lena ibhendi esiyakhayo, nokuthi singayihlukanisa kanjani:
| Ubukhulu | Ukusetshenziswa okujwayelekile | Yini ongayilindela |
|---|---|---|
| I-0.4-0.5 mm | Ukusetshenziswa kwehhovisi okulula, amakamelo abasebenzi, indawo yokugcina izinto engabizi kakhulu | Kuhle ezindaweni ezithambile; kuzophuka uma kungasetshenziswa kabi |
| 0.6 mm | Izikole, amahhovisi, amajimu — uhlobo lomsebenzi | Usinda ekushayweni nsuku zonke kanye nokushaywa okungahleliwe iminyaka eminingi |
| 0.8 mm | Imizila enabantu abaningi, amakamelo okushintshela ezimbonini | Umuzwa womnyango oqinile ngokuphawulekayo; umelana nokuqhekeka |
| 1.0 mm | Umsebenzi onzima: amafektri, amasosha, izindawo zokumba izimayini | Ukumelana okukhulu kakhulu nokubola; okunzima kakhulu futhi okubiza kakhulu |
Iqiniso eliyiqiniso lobunjiniyela: ukugxuma kusuka ku-0.4 kuya ku-0.6 mm kubaluleke kakhulu kunokugxuma kusuka ku-0.8 kuya ku-1.0 mm. Ngaphansi kuka-0.5 mm, iminyango izwakala ibuthakathaka futhi iqhekeka ngenxa yokujikijela isikhwama semali. Ku-0.6 mm enephrofayili efanele yokugoqa (okunye okwengeziwe ngalokho ngezansi), ilokha iphatha umzila wesikole iminyaka eyishumi. Ngaphezulu kuka-0.8 mm ukhokhela inzuzo yokusetshenziswa kabi, hhayi uhlobo lomkhiqizo oluhlukile.
Indlela Yokuqinisekisa Ubukhulu Obucashuniwe
Ukwethembana kuhle; i-caliper ingcono. Amazinga amathathu okuqinisekisa, ngokulandelana okukhuphukayo kokuqina:
- Isampula + i-caliper. Cela isampula yangaphambi kokukhiqiza bese ulinganisa iphaneli ngamaphuzu amathathu noma amane ukusuka emaphethelweni asikiwe (amaphethelo angafundeka kancane obukhulu kusuka kuma-burrs). I-caliper yedijithali engu-$15 ifundeka ku-0.01 mm.
- Isitifiketi sokuhlolwa kwe-Mill. Isikhungo sensimbi sikhipha isitifiketi seqoqo ngalinye lekhoyili elichaza ubukhulu bangempela. Ifektri ezimisele ingalikhiqiza, ngoba bathenga ikhoyili ukuze icaciswe — bona ukuthi ikhoyili iba kanjani amaphaneli esifundweni sethu se- indlela amalokha ensimbi enziwa ngayo.
- Ukuhlolwa komuntu wesithathu. Kuma-oda angangesitsha, engeza isilinganiso sobukhulu ohlwini lokuhlola lokuhlola ngaphambi kokuthunyelwa. Kungumshwalense oshibhile.
Isexwayiso esisodwa mayelana nendlela abaphakeli abacaphuna ngayo: buza ukuthi inombolo ingaphambi noma ngemva kokufakwa kwempuphu. Iphaneli ehlanganisiwe ingafunda ubukhulu obungu-0.1–0.2 mm ku-caliper kunensimbi engenalutho engaphansi. Isici esibalulekile ubukhulu bensimbi engenalutho, futhi isitifiketi sokugaya sisho lokho kanye.
Ubukhulu Akuyona Yonke Into: I-Fold Yenza Ingxenye Yomsebenzi
Nansi ingxenye abaqondisi abaningi abangayitholi. Iphaneli eliyisicaba elingu-0.8 mm aliqini ngokuzenzakalelayo kunele-0.6 mm eklanywe kahle, ngoba ukuqina kwephaneli kuvela ku-geometry kanye nobukhulu. Ebhulekini lokucindezela, imiphetho yephaneli ngayinye igoqwa ibe yi-90° flanges — futhi umphetho ogoqiwe wandisa ukumelana kwephaneli ekugobeni, isizathu esifanayo nesokuthi iphepha ligcine lutho ngaphandle kwephepha elifanayo eligoqiwe emseleni libambe uhlamvu lwemali.
Ngakho-ke uma uqhathanisa amalokha amabili ngesilinganiso esifanayo se-mm, bheka unqenqema lomnyango: umnyango onomphetho ogcwele kanye nesiqinisi sangaphakathi uzozizwa uqinile; umnyango oyisicaba onomphetho olula uzoguquguquka. Ubukhulu, ukwakheka kokugoqa, kanye nokwakhiwa kwamalunga - ukuqinisa okuhlanganisiwe noma amapuleti e-KD nut - kusebenzisana. Kuyindlela efanayo esiyichazayo ekuqhathaniseni kwethu kwe -KD vs okuhlanganisiwe : isakhiwo sinquma amandla ezwe langempela, hhayi inombolo eyodwa.
Amafulegi Abomvu Omhlinzeki Azungeze Ubukhulu
- Izingcaphuno ze-gauge kuphela lokho ngeke kuguqulwe kube yi-mm ngokubhala.
- "Ubukhulu obumaphakathi" ulimi — ikhoyili inebhande lokubekezelelana; isilinganiso kufanele sisho ubukhulu obujwayelekile kanye nokubekezelelana, hhayi isilinganiso esingacacile.
- Intengo ingaphansi kakhulu kwemakethe ngentengo "enkulu" — insimbi iyona ebiza kakhulu elokheni. Isilinganiso esishibhile esingaba ngu-0.8 mm ngokuvamile yi-coil engu-0.6 mm efihliwe.
- Ayikho inqubomgomo yesampula. Ifektri eqinisekayo ngemikhiqizo yayo ethunyelwa ngamasampula. uhlu lokuhlola lokuqinisekisa umkhiqizi kuphatha ukuzimisela kwesampula njengesignali eyinhloko.
Futhi fanisa imininingwane nesayithi, hhayi ukuziqhenya. Ilokha engu-1.0 mm ehhovisi elithule lokubala imali iyimali esetshenziswa ekumelaneni nokusetshenziswa kabi engeke isetshenziswe — isabelomali esifanayo sivame ukuthenga inani elingcono njengensimbi engu-0.6 mm kanye nezingidi ezingcono, amahinji, kanye nopende. Umhlahlandlela wethu welokha yesikole uhambisana nokushintshana okufanayo kwamaphrojekthi ekhampasi.
imibuzo ejwayelekile ukubuzwa
Iyini ubukhulu belokha yensimbi ejwayelekile?
Ayikho indinganiso eyodwa — impendulo eqotho ububanzi obuhambisana nokusetshenziswa. Izimboni eziningi ezisezingeni eliphezulu zakha amalokha ensimbi kusukela ku-0.4 kuya ku-1.0 mm insimbi egoqwe ngokubandayo: 0.4–0.5 mm yokusetshenziswa kwehhovisi okulula, 0.6 mm njengesici esisebenzayo sezikole namahhovisi, 0.8 mm yezindawo ezinabantu abaningi, kanye no-1.0 mm yokusetshenziswa kwezimboni okunzima.
Ingabe i-gauge noma i-mm ingcono ekuchazeni ubukhulu bensimbi?
Amamilimitha. Izinhlelo zokulinganisa ziyahlukahluka ngezwe nezinto zokwakha — inombolo efanayo yokulinganisa ihambisana nobukhulu obuhlukene eshidini lensimbi lase-US, ucingo, kanye nezindinganiso zensimbi ezingenasici. Amamilimitha awacaci kahle, yingakho amathenda aphesheya kanye nezimboni ezinkulu zicaphuna ngamamilimitha.
Ngingahlola kanjani ubukhulu bensimbi yelokha engicashuniwe?
Cela isampula yangaphambi kokukhiqiza bese ulinganisa iphaneli nge-caliper yedijithali ezindaweni eziningana kude nemiphetho esikiwe, noma udinga isitifiketi sokuhlola umshini wensimbi. Kuma-oda amakhulu, engeza ukuhlolwa komuntu wesithathu okuhlanganisa ukulinganiswa kobukhulu ohlwini lokuhlola.
Ingabe insimbi ejiyile isho njalo ilokhi eqinile?
Akunjalo ngaso sonke isikhathi. Ukuqina kwephaneli kuvela futhi kumaphrofayili onqenqema olugoqiwe adalwe kubhuleki lokucindezela — iphaneli engu-0.6 mm enezingxenyana ezifanele ezingama-90-degree ingenza kahle kakhulu kunephaneli eliyisicaba elingu-0.8 mm. Ubukhulu, ukwakheka kokugoqa, kanye nomsebenzi wokwakha amalunga ndawonye.
Ingakanani insimbi edingakalayo ngamalokha esikole?
Emaphaseji esikole lapho iminyango ishaywa khona izikhathi ezingamakhulu ngosuku, amaphaneli omzimba neminyango angu-0.6 mm ayindlela ephansi efanelekile, kanti angu-0.8 mm eminyango ezindaweni ezinzima kakhulu. Ngaphansi kuka-0.5 mm, lindela ukufiphala okubonakalayo phakathi nezikhathi ezimbalwa zesikole.
