Mumamva kuponda kwa zilembo 7 kuponyedwa mozungulira, makamaka mukamagwira ntchito ndi zojambula zochokera kumadera ena kapena makina ena otumiza kunja. Lingaliro laposachedwa ndiloti ndi gawo lokhazikika, lopanda alumali. Ndiwo msampha woyamba. M'zondichitikira zanga, sizikhala zosavuta. Si gawo chabe nambala; ndizomwe zimakhala pamphambano za kuwerengera katundu, kapangidwe ka baseplate, ndipo, movutikira kwambiri, kutsatsa kwachangu. Kulakwitsa sikutanthauza kuchedwa; kutanthauza kamangidwe kamene kamasokonekera kuchokera pansi mpaka pansi.

Kusindikiza Gawo la Makhalidwe 7

Ndiye tikukamba za chiyani kwenikweni? Zilembo 7 nthawi zambiri zimatanthawuza kachipangizo kamene kamagwiritsidwa ntchito popangira ma bolts kapena zomangira maziko, kufotokoza magawo monga m'mimba mwake, kutalika, mtundu wa ulusi, komanso nthawi zina giredi yakuthupi. Ndi condensed spec. Vuto ndilakuti, kukodzedwa kumeneku sikwachilendo. Zolemba za zilembo 7 zochokera kukampani ina ya uinjiniya zitha kutanthauza kutha kwa malata otentha, pomwe ina imagwiritsa ntchito chitsulo chopanda kaboni chokhazikika pamalopo. Ndakhala maola ambiri ndikuwunika ma code awa ndi zofunikira zenizeni zaukadaulo, ndipo kusamveka bwino ndi komwe mapulojekiti amakhazikika.

Ndikukumbukira pulojekiti yothandizira ma conveyor komwe zojambulazo zimatchula zachindunji 7-mapazi a zilembo kodi. Gulu logula zinthu, lomwe likufuna kupulumutsa ndalama, linapeza chomangira chomwe chimafanana ndi m'mimba mwake ndi kutalika kwake. Iwo anaphonya kuti code imafuna mphamvu zokolola za 8.8, ndipo zomwe zinafika zinali giredi 4.8. Kusiyana kwake? Ductility yofunikira motsutsana ndi brittle point ya kulephera pansi pa katundu wamphamvu. Tidazipeza poyang'anira kuyika, koma zidayimitsa ntchito kwa milungu itatu. Chotengera: kachidindo ndi poyambira kukambirana, osati kutha kwake.

Apa ndipamene nkhani za malo zili zofunika. Ngati mukugwira ntchito ndi malo opangira zinthu m'malo ngati Chigawo cha Yongnian ku Handan, Hebei, yomwe imadziwika kuti ndi gawo lalikulu kwambiri lazinthu zopanga zinthu ku China, mutha kupanga zambiri. Kampani yomwe ili kumeneko, ngati Handan Zitai Fastener Manufacturing Co., Ltd., imagwira ntchito mkati mwa chilengedwechi. Kuyandikana kwawo ndi mayendedwe akuluakulu monga Beijing-Guangzhou Railway ndi National Highway 107 simalo ogulitsa okha; imatanthawuza kuti zinthu zikuyenda bwino pamadongosolo ochulukira komanso olemetsa. Koma ngakhale ndi mwayi wotero, kukambirana kwatsatanetsatane ndikofunikira. Simungangotumiza imelo ndi kuyembekezera kuti ifanane bwino.

The Specification Dialogue: Kupitirira Code

Izi zimatsogolera ku njira yothandiza. Ndikafunika kumasulira a 7-mapazi a zilembo callout mu dongosolo logula, sitepe yoyamba ndi pepala lowonongeka. Timalemba mawonekedwe aliwonse omwe amaganiziridwa: m'mimba mwake mwadzina, phula, kutalika kwa ulusi, kutalika kwa shank, mtundu wamutu (ngati ulipo), mtundu wazinthu (mwachitsanzo, Q235B, 35, 45), makina amakina, chithandizo chapamwamba (galvanizing, zinc plating, black oxide), ndi milingo ina iliyonse (GB, DIN, ISO). Tsambali limakhala Baibulo laukadaulo la RFQ.

Nayi vuto lodziwika bwino: chithandizo chapamwamba poteteza dzimbiri. Khodi silingatchule, koma malo oyika amatero. Kwa maziko akunja m'nyengo yachinyontho, galvanizing yotentha-dip ndi yosakanizidwa. Ndawonapo magulu akufika ndi zokutira zopyapyala za electroplated chifukwa unali mulingo wa ogulitsa pama codewo, osayenerera kugwiritsa ntchito. Kulephera kumawoneka ngati dzimbiri mkati mwa chaka ndikuchepetsa kuchepa kwa nthawi. Tsopano, nthawi zonse timawonjezera zolemba zachilengedwe kuzinthu zathu.

Kugwira ntchito ndi opanga apadera kumathandizira izi. Mukakhala ndi gulu logulitsa zaukadaulo kwa wopanga, tinene, lomwe limafotokoza kuthekera kwake monga Zitai Fasteners amachitira, kutsindika za malo ake opangira zinthu zazikulu - simumangolankhula ndi wogawa. Mukhoza kukambirana zazitsulo, ndondomeko yopangira ulusi (yogubuduza vs. odulidwa), ndi kayendetsedwe ka khalidwe la kulekerera kwapakati. Mutha kufunsa, Pamakhodi a zilembo 7 akutanthauza kugwiritsidwa ntchito m'dera la zivomezi, mungapangire ulusi wotalikirana wosiyana kapena zida zapamwamba? Ndiko kukambirana komwe kumalepheretsa kulephera.

Logistics ndi Heavy Factor

Chomwe chimanyalanyazidwa nthawi zambiri pa zomangira maziko ndi mawonekedwe awo enieni. Kutumiza mazana angapo 7-mapazi a zilembo mabawuti a nangula, iliyonse mwina 1.2 mita utali ndi 36mm m'mimba mwake, ndi yolemera kwambiri komanso yovuta. Logistics sichinthu chongoganizira; ndi gawo lalikulu la mtengo ndi kuwunika zoopsa. Apa ndi pamene malo ogulitsa amatsimikizira kufunika kwake.

Wopanga wokhazikika pabwalo ngati Yongnian, yemwe ali ndi mwayi wopita ku Beijing-Shenzhen Expressway ndi National Highway 107, ali ndi mwayi wophatikizira katundu wapakhomo komanso mwayi wopita kudoko kutumiza kunja. Imachepetsa kugwirira, imachepetsa chiwopsezo cha kuwonongeka paulendo (zingwe zopindika ndizovuta kukonza pamalopo), ndipo zimatha kumeta masiku ofunikira kwambiri. Ndayerekeza zochitika zomwe kufunafuna kuchokera kumadera omwe siapadera kumawonjezera kupitilira 15% pamtengo womwe udafika pamiyendo yambiri.

Kupaka kumafunikanso. Izi sizinthu zazing'ono. Ayenera kukulungidwa kapena kumangidwa m'mitolo m'njira yoletsa kuwonongeka kwa ulusi panthawi yonyamula katundu m'nyanja. Wopanga wabwino amadziwa izi ndipo amamanga zoyikapo zolimba ngati gawo la ntchitoyo. Ndi tsatanetsatane yaying'ono yomwe imalankhula ndi zochitika zothandiza.

Case Point: The Adjustable Baseplate Fiasco

Phunziro langa lophunzitsa kwambiri pamutuwu linachokera ku pulojekiti yokhudzana ndi makina akuluakulu osinthika. Zojambulazo zinali ndi muyezo 7-mapazi a zilembo spec kwa mabawuti a nangula. Komabe, mapulateletiwo anali ndi mabowo okulirapo kuti azitha kuyanjanitsidwa komaliza asanagwetse. Utali wokhazikika wa bawuti, malinga ndi kachidindo, sunali wokwanira kuwerengera mtedza ndi mawaya ofunikira pansi.

Sitinagwire mpaka kukhazikitsa. Mabawuti anali aafupi kwambiri. Yankho lochokera ku gulu lamunda linali kuwotcherera zowonjezera pazitsulo-zochita zomwe zimawononga kotheratu chithandizo cha kutentha ndi makina azitsulo, kupanga malo ofooka kwambiri. Tinayenera kukana gulu lonselo. Kukonzekera kunali kukonzanso kwathunthu ndi chizolowezi, chosakhazikika kutalika, chomwe wopanga, kwa ngongole yawo, adatembenuka mwachangu chifukwa anali ndi zida zopangira komanso zopangira m'nyumba. Phunzirolo linali lopweteka: zowerengera sizingawunidwenso patokha. Iyenera kuyang'aniridwa motsutsana ndi msonkhano weniweni - makulidwe a baseplate, wosanjikiza wa grout, dongosolo lowongolera, ndikuwonetsa ulusi wofunikira.

Tsopano, mndandanda wathu umaphatikizapo kuwerengera kutalika kwa bawuti komwe kumakhala mu zigawo zonsezi. Khodi ya zilembo 7 imatipatsa kukula koyambira ndi giredi, koma tili ndi kutalika komaliza.

Malingaliro Omaliza: Ndi Za Kulimbikira Kwambiri

Kotero, pambuyo pa zonsezi, ndi malingaliro otani pa 7-mapazi a zilembo? Ndichidule chothandiza, koma ndodo yowopsa. Imayimira zidziwitso zochepa. Kuchitenga ngati kugulidwa kwathunthu ndi chiopsezo cha akatswiri.

Kudalirika kumachokera m'njira yomwe mumakulunga mozungulira: kuwonongeka kwaukadaulo, kusankha kwa ogulitsa kutengera luso la kupanga ndi kukonza, komanso cheke chomaliza motsutsana ndi chojambula chonse. Ndiko kusiyana pakati pa kugula chinthu ndi uinjiniya chigawo chimodzi.

Pamapeto pake, mapulojekiti opambana amatulutsa zinthu izi kuchokera kwa othandizana nawo omwe amamvetsetsa cholinga cha uinjiniya kumbuyo kwa code, osati ma code okha. Izi zimafuna kuyang'ana kupyola kalozerayo ndikupita kumalo oyambira, malo ogulitsira, ndi labu yabwino. Ndipamene mumapeza maziko enieni a dongosolo lanu.
