Anthu ambiri akamva 'phazi la ambulera la chogwirira cha ambulera,' amaganiza za kapu ya raba yomwe ili kumapeto. Ndi malo osawoneka bwino amakampani - kuyang'ana pansalu ya denga kapena zimango zomangira phazi ngati chinthu chongoganizira pang'ono. M'malo mwake, chigawocho ndi malo oyamba olumikizirana ndi nthaka, tebulo, kapena mbedza. Mapangidwe ake ndi kukhulupirika kwake kumapangitsa kukhazikika, kukana kuvala, komanso chitetezo cha ogwiritsa ntchito. Ndawonapo ma prototypes ambiri akulephera chifukwa chogwiriracho chinali changwiro, koma phazi linali chowonjezera chamsika chomwe chimang'ambika pansi pa torque yaying'ono kapena kuvala bwino mkati mwa nyengo, kupangitsa kuti ambulera yonse ikhale yosavuta kutsetsereka. Si kapu chabe; ndiye nangula.

Malingaliro Olakwika a Zakuthupi ndi Zowona Zaku Grip

Zosankha zosasinthika kwazaka zambiri zakhala mphira wosavuta wopangidwa kapena PVC. Ndiwotsika mtengo ndipo imapereka kukangana koyambirira. Koma nazi zomwe zachitika pakuyesa kwapadziko lonse lapansi: kuwonongeka kwa chilengedwe ndi nkhanza. Phazi lomwe latsala pakhonde lowotchedwa ndi dzuwa m'chilimwe ku Arizona limakhala lolimba. Munthu akauthiridwa nthawi zonse mu udzu wonyowa kapena pamalo okwera amchere, amatha kunyozeka kapena kuterera. Njira yogwirira - yomwe nthawi zambiri imangokhala yozungulira - ndiyosakwanira popumira. Tinasamukira ku thermoplastic elastomers (TPEs) zokhala ndi UV komanso kukana kwa ozoni, ndipo zinali zosintha pamasewera akunja. Durometer (kuuma) ndikofunikira kwambiri; zofewa kwambiri, ndipo deforms kalekale pa otentha konkire; cholimba kwambiri, ndipo chimakanda pamwamba ndi kutsetsereka. Kupeza bwinoko ndizochitika zenizeni, osati kungochita masewera olimbitsa thupi.

Ndiye pali njira yomatira. Kungokankhira phazi pa ndodo yachitsulo ndiko njira yotaya. Tinaphunzira kuphatikiza nthiti zamkati kapena kachipangizo kakang'ono pamapangidwe a ndodo, ophatikizidwa ndi geometry yamkati yogwirizana paphazi. Nthawi zina, zomatira zolimbana ndi nyengo ndizofunikira, koma ziyenera kukhala zolondola - ena amadya TPE pakapita nthawi. Ndikukumbukira gulu lochokera kwa supplier, Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., kumene nkhaniyo sinali yokhazikika yomwe iwo ankadziwika nayo, koma njira yowonjezereka ya gawo la phazi lachitsulo ndi labala. Chomangiracho chinalephera pakuyesa chinyezi. Malo omwe amakhala ku Yongnian, malo akulu akulu aku Hebei, kutanthauza kuti anali ndi zitsulo zozizira kwambiri, koma zomangira za polima mpaka zitsulo zimafunikira kulimba. Linali phunziro labwino pazamalonda apadera; ngakhale abwino kwambiri m'dera limodzi amakhala ndi mapindikidwe ophunzirira m'malo oyandikana nawo.

Njira yogwirira ntchito ndi tsatanetsatane wina. Tidayesa njira yamitundu yambiri, pafupifupi ngati kaboti kakang'ono koyenda maulendo, chifukwa maambulera amaima pa turf. Zinagwira ntchito koma zinali zovuta kuzigwetsa. Njira zosavuta, zozama kwambiri zoyambira pakati zidakhala zodalirika pakukhetsa madzi ndi matope popanda kusokoneza kupanga. Cholinga sikuyambitsanso matayala; ndiko kuletsa ambulera kukhala yowopsa.

Kuphatikiza Kwamapangidwe: Kuposa Kapu

Apa ndipamene uinjiniya weniweni amalowamo. Phazi si nthawi zonse kukhala chipewa chomaliza. M'maambulera ambiri a cantilever kapena amsika, pansi pa chogwiriracho ndi gawo la njira yotseka kapena yopendekera. Phazi lingafunike kuyika kasupe, pini, kapena kupereka malo oyambira. Ndathyola mayunitsi pomwe phazi linali lophatikizana la nayiloni, chotsukira chitsulo, ndi mphira kunja zonse zowumbidwa. Ngati chochapira chamkaticho sichinagwirizane bwino kapena kalasi ya nayiloni yolakwika, mumamva kugwedezeka pamene mukukonzekera kupendekera, kapena kuipiraipira, kuvala msanga komwe kumabweretsa kugwa mwadzidzidzi.

Nthawi ina tidayesa kukulitsa phazi lachilengedwe chonse ndi spike yomangidwira, yokhoza kubweza pa nthaka yofewa komanso mphira wopindika pamalo olimba. Kunali kulephera kwa msika. Zigawo zosuntha zodzaza ndi mchenga, ma pivot ndi dzimbiri, ndipo zimawonjezera mtengo ndi mfundo zolephera ku gawo lodalirika kwambiri. Kodi tikuphunzirapo chiyani? Nthawi zina, yankho lokongola kwambiri ndi phazi limodzi, lopangidwa ndi cholinga cha mtundu wa ambulera. Ambulera yolemera yoyambira imafunikira phazi lalikulu, lathyathyathya kuti ligawidwe; ambulera ya m'mphepete mwa nyanja yopepuka ingafunike phazi lakuthwa. Universality nthawi zambiri imasokoneza ntchito yayikulu.

Kugwirizana ndi mtengo ndikofunikira. Kwa mitengo yachitsulo, mapeto ake nthawi zambiri amawotchedwa kapena amawotcha. Phazi lakumapeto koyaka liyenera kukhala lopindika mkati ndi milomo yolimba kuti igwire motowo. Polumikiza ulusi, phazi lokha likhoza kukhala ndi choyikapo chachitsulo chopangidwamo. Apa ndipamene kuyika kwa katswiri wa fastener kumakhala kofunikira. Mulingo wa ulusi, mphamvu yokoka ya choyikapo, ndi kukana kwake kwa dzimbiri m'malo onyowa sizingakambirane. Kampani ngati Zitai Fastener, yomwe ili pa mphambano yaikulu ya mayendedwe pafupi ndi njanji ya Beijing-Guangzhou Railway, imamvetsetsa momwe mayendedwe ndi kuchuluka kwa zida zachitsulo zenizeni. Kupeza choyikapo chotere kuchokera kwa iwo n'komveka, koma kuumba mozungulira kuyenera kufotokozedwa molumikizana kuti tipewe mipata yaying'ono pomwe madzi amalowera kumayambitsa dzimbiri.

Njira Zolephera ndi Zowonera M'munda

Mumaphunzira zambiri kuchokera ku zobwerera ndi zolephera zam'munda kuposa mayeso aliwonse a labu. Kulephera kofala kwambiri ndiko kudzipatula. Phazi limangogwa n’kusochera. Chachiwiri ndikugawanika - zinthuzo zimang'ambika kuchokera pakati, nthawi zambiri kuchokera ku UV komanso kupsinjika kosalekeza kwa mtengo wofuna kusinthasintha pang'ono mkati mwake. Chachitatu ndi psinjika set: phazi flattens kwamuyaya, kutaya mbiri yake ndi kugwira.

Ndinakhala pamalo ena ochezera a m'mphepete mwa nyanja ndikuyang'ana maambulera awo obwereketsa. Mapazi anali odulidwa mbali imodzi chifukwa ogwira ntchito ankakokera maambulera otsekedwawo m'malo mowanyamula. Sitinapangire kuti ma lateral abrasion. Zinadziwitsanso mapangidwe amtsogolo pomwe tidagwiritsa ntchito kaphatikizidwe kolimba pang'ono, kosagwirizana ndi abrasion pa equator ya phazi, ndikusunga nkhope yolumikizirana kuti igwire. Zinawonjezera sitepe pakuumba koma kuwirikiza kawiri moyo wautumiki m'malo ovutawo.

Kulephera kwina kosadziwika bwino ndiko kuchitapo kanthu kwa mankhwala. Mwini nyumba wapamwamba adagwiritsa ntchito mtundu wina wa zotsukira padenga zomwe zidasiya zotsalira. Pulasitiki mu phazi lathu la PVC lokhazikika linasamuka litakhudza, ndikusiya filimu yomata ndi phazi lopuwala, lolimba. Tinayenera kusinthira ku gulu la mphira la EPDM lopanda pulasitiki pamzere weniweniwo. Izi ndi zinthu zomwe simuzipeza m'buku; mumawapeza mumaimelo amakasitomala okwiya komanso kuyendera malo.

Dansi Yopanga ndi Kupeza

Kugwiritsira ntchito phazi ndikosavuta mwachinyengo, chifukwa chake nthawi zambiri kumasiyidwa mpaka mphindi yomaliza. Koma nkhungu yopangidwa molakwika yokhala ndi kuziziritsa kosakwanira imatha kuyambitsa zipsera kapena zofooka. Kutulutsa mpweya ndikofunikira kuti mupewe kuwombera pang'onopang'ono mwatsatanetsatane. Pachigawo chopangidwa mazana masauzande, monga ambulera yayikulu OEM, kuchepetsa theka lachiwiri la nthawi yozungulira kapena 1% kupulumutsa zinthu ndikwambiri. Uku ndiye kugunda kwamtengo wapatali.

Kupeza kumaphatikizapo katatu: wogulitsa zinthu, wopanga nkhungu, ndi chophatikiza chomaliza. Nthawi zina ndi bwino kukhala ndi ambulera fakitale gwero phazi mwachindunji nkhungu katswiri. Nthawi zina, makamaka pamapangidwe aukadaulo okhala ndi zoyika zachitsulo, ndikwabwino kupeza gawo lonse kuchokera kwa wothandizira m'modzi yemwe amayang'anira kuphatikiza. Kwa zida zachitsulo, kuyanjana ndi wopanga zomangira zodzipatulira ndizomveka. Kampani ngati Handan Zitai Fastener, yochokera ku gawo lalikulu kwambiri la China yopanga gawo, ili ndi sikelo ndi ukatswiri wopangira zoyikapo zitsulo zosasinthasintha, zokutira kapena nsonga za ulusi. Ubwino wawo wamakonzedwe, pokhala moyandikana ndi misewu yayikulu ndi njanji, zikutanthauza kuti amatha kudyetsa mizere yongopanga nthawi yake modalirika. Mfungulo ndikuwapatsa zolemba zenizeni za mtundu wa zokutira (mwachitsanzo, zokutira zinki zokhala ndi chromate yachikasu pofuna kukana mchere) komanso kulolera molimba.

Kuyankhulana ndizovuta zobisika. Kufotokozera zofunikira za durometer, mphamvu zamakokedwe, ndi zofunikira zoyika psinjika ku sitolo yowumba, ndiyeno kukana kwa dzimbiri ndi kalasi ya ulusi kwa zitsulo zazitsulo, zimafuna mapepala omveka bwino a deta. Gulu lolephera nthawi zambiri limachokera ku lingaliro kapena chinthu cholowa m'malo. Ndimasunga laibulale yamapazi olephera - opunduka, osungunuka, osasunthika - monga chida chothandiza kwambiri cholumikizirana ndi ogulitsa. Mukuona izi? Sitingakhale nazo izi.

Kutsiliza: Lemekezani Phazi

Choncho, phazi chogwirira ambulera. Ndi phunziro la kudzichepetsa kwa opanga mankhwala. Zimakuphunzitsani kuti malo aliwonse okhudzana ndi zinthu, kuti kupsinjika kwa chilengedwe kumakhala kochulukira, komanso kuti gawo lowoneka bwino kwambiri litha kukhala cholumikizira cha sayansi ya zinthu, kapangidwe ka makina, komanso kasamalidwe kazinthu. Izo siziri za kupanga izo zapamwamba; ndi za kupanga izo kuzimiririka kudzera opanda cholakwa ntchito. Cholinga chake ndi chakuti wogwiritsa ntchito asaganize konse—mpaka atagwiritsa ntchito ambulera yotsika mtengo yomwe imatsetsereka ndi kugwa, ndiyeno amvetsetsa kufunika kwake mosabisa. Kuchikonza ndiko kupambana kwachete, komwe kumapangitsa kuti dongosolo lonse likhale lolimba, mvula kapena kuwala.
