Pitani ku nkhani
Yankho lachangu: Kukhuthala kwa loko yachitsulo kumafotokozedwa bwino mu mamilimita, osati gauge — makina oyezera amasiyana malinga ndi dziko ndi zinthu, pomwe mm ndi yomveka bwino. Maloko abwino amapangidwa kuchokera ku chitsulo chozizira cha 0.4–1.0 mm: 0.4–0.5 mm kuti chigwiritsidwe ntchito muofesi yopepuka, 0.6 mm ngati muyezo wamasukulu ndi maofesi, 0.8 mm m'malo odutsa anthu ambiri, ndi 1.0 mm kuti chigwiritsidwe ntchito kwambiri. Tsimikizani mtengo uliwonse ndi chitsanzo choyezedwa ndi caliper kapena satifiketi ya mphero yachitsulo.
Wogula wina ku Nigeria nthawi ina ananditumizira mtengo wochokera kwa wogulitsa amene ankapereka makabati a “22 gauge” pamtengo wabwino kwambiri. Anandifunsa tanthauzo la 22 gauge mu mamilimita kuti athe kuyerekeza ndi zomwe tinapereka za 0.6 mm. Ine ndinasintha, ndipo makabati ake “otsika mtengo” a 22-gauge anali achitsulo chopyapyala kuposa athu pamtengo wapamwamba. Sanafunsenso za makabati a gauge.
Kunenepa ndi komwe ogula amaika patsogolo - ndipo ogulitsa nambala imodzi nthawi zambiri amakoka. Umu ndi momwe mungaganizire bwino za makulidwe a loko yachitsulo.
Chifukwa Chake "Gauge" Ndi Msampha kwa Ogula Padziko Lonse
Gauge ndi njira yakale yowerengera manambala komwe nambala yapamwamba imatanthauza chitsulo choonda - ndipo mapu amasiyana pakati pa miyezo. Gauge ya chitsulo yaku US, British Standard Wire Gauge, ndi gauge yosapanga dzimbiri zonse zimapatsa nambala yofanana ma millimeter osiyanasiyana. Wogulitsa akunena kuti "gauge 18" popanda kutchula muyezowo akunena nambala yomwe ingatanthauze makulidwe osiyanasiyana.
Kusintha kosakhazikika pansi pa muyezo wamba wa pepala lachitsulo la ku America, pongoyang'ana kokha:
| Gauge (pepala lachitsulo la ku America, pafupifupi) | makulidwe |
|---|---|
| 26 kuyeza | ≈ 0.45 mm |
| 24 kuyeza | ≈ 0.6 mm |
| 22 kuyeza | ≈ 0.75 mm |
| 20 kuyeza | ≈ 0.9 mm |
| 18 kuyeza | ≈ 1.2 mm |
Onani msampha: misika ina imagwiritsa ntchito mawu akuti "gauge" pogwiritsa ntchito tebulo lina, ndipo ogulitsa ena amangogwiritsa ntchito mawuwa kuti amveke bwino akamatumiza chilichonse chomwe chidachitika. Mamilimita amachotsa kusamveka bwino konse. Ichi ndichifukwa chake ma tender apadziko lonse lapansi, ndi mapepala athu a quotation, amalemba makulidwe mu mm - ndipo chifukwa chake tikukulimbikitsani kufunsa wogulitsa aliyense, nambala iliyonse yomwe atchula, "ndipo kodi mu mamilimita ndi chiyani, pa satifiketi ya mphero?"
Kukhuthala kwa Chosungira Chitsulo pogwiritsa ntchito Chikwama
Palibe "kukhuthala kokhazikika" komwe kulipo padziko lonse lapansi — pali malo ogwirira ntchito, ndipo malo oyenera mkati mwake amadalira zomwe locker idzakhala nayo. Uwu ndi mzere womwe timapanga, ndi momwe tingaugawire:
| makulidwe | Kugwiritsa ntchito mwachizolowezi | Zimene muyenera kuyembekezera |
|---|---|---|
| 0.4-0.5 mm | Kugwiritsa ntchito ofesi mopepuka, zipinda za antchito, malo osungiramo zinthu ochepa | Zabwino pa malo odekha; zidzapindika ngati zitagwiritsidwa ntchito molakwika |
| 0.6 mamilimita | Masukulu, maofesi, malo ochitira masewera olimbitsa thupi — ntchito yapadera | Amapulumuka kumenyedwa tsiku ndi tsiku ndi kumenyedwa mwachisawawa kwa zaka zambiri |
| 0.8 mamilimita | Makonde okhala ndi magalimoto ambiri, zipinda zosinthira zovala zamafakitale | Kumveka bwino kwa chitseko; kumateteza kupindika |
| 1.0 mamilimita | Ntchito yaikulu: mafakitale, asilikali, malo opangira migodi | Kukana kwambiri kubowola; kolemera kwambiri komanso kokwera mtengo kwambiri |
Zoona zenizeni zaukadaulo: kulumpha kuchokera pa 0.4 mpaka 0.6 mm n'kofunika kwambiri kuposa kulumpha kuchokera pa 0.8 mpaka 1.0 mm. Pansi pa 0.5 mm, zitseko zimakhala zosalimba komanso zopindika chifukwa cha kugwedezeka kwa chikwama. Pa 0.6 mm yokhala ndi ma profiles oyenera opindika (zambiri pansipa), loko imagwira ntchito pa khonde la sukulu kwa zaka khumi. Pamwamba pa 0.8 mm mukulipira ndalama zothandizira nkhanza, osati kalasi ina ya zinthu.
Momwe Mungatsimikizire Kunenepa Komwe Mwatchulidwa
Kudalirana ndi kwabwino; caliper ndi yabwino. Magawo atatu otsimikizira, motsatira ndondomeko yowonjezereka ya kukhwima:
- Chitsanzo + caliper. Funsani chitsanzo chisanapangidwe ndipo yesani bolodilo pamalo atatu kapena anayi kutali ndi m'mphepete mwadula (m'mphepete mwake mutha kuwerenga makulidwe pang'ono kuchokera ku ma burrs). Caliper ya digito ya $15 imawerengedwa kufika pa 0.01 mm.
- Satifiketi yoyeserera ya mphero. Mphero yachitsulo imapereka satifiketi ya gulu lililonse la koyilo yomwe imafotokoza makulidwe enieni. Fakitale yodalirika imatha kupanga, chifukwa imagula koyilo malinga ndi zomwe zanenedwa - onani momwe koyilo imakhalira mapanelo mu ndondomeko yathu ya momwe makabati achitsulo amapangidwira.
- Kuyang'ana kwa chipani chachitatu. Mukaitanitsa chidebe chachikulu, onjezani muyeso wa makulidwe pa mndandanda wowunika zinthu musanatumize. Ndi inshuwaransi yotsika mtengo.
Chenjezo limodzi lokhudza momwe ogulitsa amanenera: funsani ngati nambalayo ndi ya ufa usanayambe kapena utatha . Gulu lokutidwa limatha kuwerenga makulidwe a 0.1–0.2 mm pa caliper kuposa chitsulo chopanda kanthu chomwe chili pansi pake. Chofunika kwambiri ndi makulidwe achitsulo chopanda kanthu, ndipo satifiketi ya mphero imanenadi zimenezo.
Kunenepa Sikonse: Kupindika Kumachita Hafu ya Ntchito
Nayi gawo lomwe malangizo ambiri ogula amaphonya. Panel yathyathyathya ya 0.8 mm siimalimba yokha kuposa panel yopangidwa bwino ya 0.6 mm, chifukwa kulimba kwa panel kumachokera ku geometry monga makulidwe. Pa press brake, m'mphepete mwa panel iliyonse imapindidwa kukhala ma flange a 90° — ndipo m'mphepete wopindidwa umachulukitsa kukana kwa panel kuti isapindike, chifukwa chomwecho pepala siligwira chilichonse koma pepala lomwelo lopindidwa mu njira limasunga ndalama.
Kotero mukayerekeza ma locker awiri pa mm spec yomweyi, yang'anani m'mphepete mwa chitseko: chitseko chokhala ndi mpiringidzo wozungulira wonse ndi cholimba chamkati chidzamveka cholimba; chitseko chomwe chili ngati pepala lathyathyathya chokhala ndi m'mphepete wosavuta chidzasinthasintha. Kukhuthala, kapangidwe ka kupindika, ndi kapangidwe ka ma joint — zolimbitsa zolumikizidwa kapena mbale za nati za KD — zimagwira ntchito limodzi. Ndi mfundo yomweyi yomwe timaifotokoza poyerekeza kwathu kwa KD vs welded : kapangidwe kake kamasankha mphamvu yeniyeni, osati nambala imodzi.
Mbendera Zofiira Zozungulira Kukhuthala
- Ma quotes okha zomwe sizingasinthe kukhala mm polemba.
- "Kukhuthala kwapakati" chilankhulo — chozungulira chili ndi gulu lololera; mawuwo ayenera kufotokoza makulidwe ndi kulekerera, osati avareji yosamveka bwino.
- Mtengo wotsika kwambiri pamsika pa "cholimba" - chitsulo ndiye mtengo waukulu kwambiri mu loko. Mtengo wotsika mtengo wa 0.8 mm nthawi zambiri umakhala wobisika ndi coil ya 0.6 mm.
- Palibe chitsanzo cha ndondomeko. Fakitale yodalirika ndi zitsanzo zake zapadera. mndandanda wotsimikizira wopanga imaona kufunitsitsa kwa chitsanzo ngati chizindikiro chachikulu.
Ndipo gwirizanitsani zomwe zili patsamba lino, osati ndi kunyada. Locker ya 1.0 mm mu ofesi yowerengera ndalama yokhala chete ndi ndalama zomwe zimagwiritsidwa ntchito polimbana ndi nkhanza zomwe sizingagwiritsidwe ntchito — bajeti yomweyi nthawi zambiri imagula mtengo wabwino kuposa chitsulo cha 0.6 mm kuphatikiza maloko, ma hinges, ndi zokutira zabwino. Buku lathu lotsogolera locker kusukulu limaperekanso njira yofanana yosinthira mapulojekiti akusukulu.
Mafunso Ofunsidwa Kawirikawiri
Kodi makulidwe a locker yachitsulo ndi otani?
Palibe muyezo umodzi — yankho loona mtima ndi lofanana ndi lomwe lingagwiritsidwe ntchito. Mafakitale ambiri abwino amapanga maloko achitsulo kuyambira 0.4 mpaka 1.0 mm okhala ndi chitsulo chozizira: 0.4–0.5 mm kuti agwiritsidwe ntchito muofesi yopepuka, 0.6 mm ngati chitsanzo cha ntchito m'masukulu ndi maofesi, 0.8 mm m'malo omwe magalimoto ambiri amadutsa, ndi 1.0 mm kuti agwiritsidwe ntchito m'mafakitale akuluakulu.
Kodi geji kapena mm ndi bwino pofotokoza makulidwe a chitsulo?
Mamilimita. Makina oyezera amasiyana malinga ndi dziko ndi zinthu — nambala yoyezera yomweyi imawonetsa makulidwe osiyanasiyana mu pepala lachitsulo la ku America, waya, ndi miyezo yosapanga dzimbiri. Mamilimita ndi omveka bwino, ndichifukwa chake ma tender apadziko lonse lapansi ndi mafakitale akuluakulu amatchula mu mm.
Kodi ndingayang'ane bwanji makulidwe achitsulo a loko yomwe ndanena?
Funsani chitsanzo chisanapangidwe ndipo yesani bolodi ndi choyezera cha digito pamalo angapo kutali ndi m'mphepete mwa chodulidwa, kapena funsani satifiketi yoyesera mphero ya choyezera chitsulo. Pa maoda akuluakulu, onjezani kuwunika kwa chipani chachitatu komwe kumaphatikizapo muyeso wa makulidwe mu mndandanda wotsatira.
Kodi chitsulo chokhuthala nthawi zonse chimatanthauza loko yolimba?
Osati nthawi zonse. Kulimba kwa panel kumachokeranso ku ma profiles opindidwa omwe amapangidwa pa press brake — panel ya 0.6 mm yokhala ndi ma flanges oyenera a madigiri 90 imatha kugwira ntchito bwino kuposa panel yathyathyathya ya 0.8 mm. Kukhuthala, kapangidwe kopindika, ndi ntchito yomanga ma connection pamodzi.
Kodi makabati a sukulu amafunikira makulidwe achitsulo otani?
Pa makonde a sukulu komwe zitseko zimatsekeredwa kambirimbiri patsiku, ma panel a thupi ndi zitseko a 0.6 mm ndi omwe amafunikira kwambiri, ndipo 0.8 mm pa zitseko zomwe zili m'malo ovuta kwambiri. Pansi pa 0.5 mm, yembekezerani kuoneka koboola mkati mwa nthawi yochepa ya sukulu.
