Mitundu ya manja yolumikizana ndi rebar yomwe imagwiritsidwa ntchito kwambiri pamsika

Choyamba, tapered ulusi kugwirizana malaya: Pambuyo kulimbikitsa wapadera wa kutsogolo mapeto a rebar ulusi ndi kugwirizana chidutswa conical ulusi chinkhoswe mfundo. Kubadwa kwa ulusi wolumikizira ulusi wopindika kumathetsa kuipa kwa manja okanda mkono wolumikiza. Mitu ya ulusi wa taper ndi yopangidwa kale, ndipo kulumikizana kwapatsamba kumakhala kwakanthawi. Malowa amangofuna wrench ya torque kuti agwire ntchito popanda kufunikira kusuntha zipangizo ndi kukoka mawaya, ndipo amalandiridwa bwino ndi makampani omangamanga. Komabe, khalidwe la ulusi wa tapered wolumikiza sleeve silokhazikika. Chifukwa kukula kwa ulusi wopangidwa ndi makina kumafooketsa chigawo chapakati cha chitsulo choyambira kenako kumachepetsa mphamvu ya olowa, nthawi zambiri amafika 85 mpaka 95% ya mphamvu yokhazikika ya zinthu zoyambira. Pali mtunda wina pakati paukadaulo wolumikizana ndi ulusi waku China komanso kufananitsa kwapadziko lonse lapansi.

Limodzi mwa mavuto odziwika kwambiri ndiloti mamvekedwe ndi amodzi. Rebar kuchokera m'mimba mwake ya 16 ~ 40mm ndi 2.5mm, ndipo phula la 2.5mm ndiloyenera kwambiri kulumikiza nsonga ya 22mm. Kulimba kwazitsulo zolimba kwambiri kapena zowonda kwambiri zachitsulo sikoyenera, makamaka ndi 36mm m'mimba mwake ndi 40mm zitsulo zachitsulo cholumikizira ulusi, n'zovuta kufika ku mphamvu yeniyeni yazitsulo zazitsulo ndi nthawi 0,9. Magawo ambiri opanga amati amafika ku mphamvu ya zinthu zamakolo zazitsulo zolimbitsa zitsulo, zomwe ndikugwiritsa ntchito ntchito yapamwamba kwambiri yazitsulo zazitsulo zachitsulo, ndiko kuti, mphamvu yogwira ntchito yachitsulo ndi yaikulu kuposa mtengo wamtengo wapatali wa mphamvu yamakomedwe yazitsulo. Chifukwa ukadaulo wolumikizira ulusi wa taper uli ndi mawonekedwe omangika mwachangu komanso mtengo wotsika, wagwiritsidwanso ntchito pamlingo wokulirapo kuyambira kukhazikitsidwa koyambirira kwa 1990s. Komabe, chifukwa cha kuipa kwake, pang'onopang'ono amalumikizidwa ndi manja ndi ulusi wowongoka.

Pakati pawo, Yida Rebar Connection Technology Co., Ltd. ndiye mtsogoleri pamakampani olumikizana ndi manja.

Manja olumikizana ndi ulusi wowongoka makamaka amakhala ndi manja owongoka komanso ulusi wowongoka. Njira ziwirizi zimagwiritsa ntchito njira zosiyanasiyana zogwirira ntchito kuti ziwonjezere mphamvu ya ulusi wolimbitsa mutu, ndikufika pa cholinga cholimba cha mgwirizano ndi zitsulo zolimbitsa thupi.

Ulusi wowongoka wolumikiza mkono ndi wolumikizana womwe umapangidwa ndi ulusi wowongoka ndi membala wolumikizana womwe umapangidwa ndi kusokoneza mutu wa bar. Ntchito yake ndi:

Choyamba, kutha kwa bar yolimbikitsa kumakhumudwitsidwa ndi zida zosokoneza, ndiyeno ulusi umakonzedwa. Ulusi wa ulusi siwochepa kuposa momwe zimakhalira ndizitsulo zowonjezera, kotero kuti cholumikizira ndi maziko ake amafikira mphamvu yomweyo. Ulusi wowongoka wapadziko lonse lapansi wolumikizira ulusi, mapeto ake achitsulo amakhala ndi kukhuthala kotentha komanso kozizira. Kutenthetsa kutentha makamaka kumachotsa kupsinjika kwamkati panthawi yosokoneza, koma ndalama zogulira zida zotenthetsera ndizokwera. China chowongoka chowongoka cholumikizira manja, chitsulo chake chimathera makamaka chozizira komanso chokhuthala, chimakhala ndi kufunikira kwakukulu kwa ductility yachitsulo, ndipo ndizovuta kuwongolera kulimba kwachitsulo ndi ductility otsika, ndipo ndikosavuta kuukira mawonekedwe a fracture yophulika.

Manja olumikiza ulusi wokhuthala ndi wowongoka ali ndi zabwino zamphamvu kwambiri, kumanga mwachangu pamalopo, kutsika kwamphamvu kwa wogwira ntchito, kukonzekeretsa koyambirira kwa ulusi wowongoka wazitsulo zachitsulo, ndi kulumikizana pamalopo kuti agwire ntchito yoyika. Kusowa kwake ndikuti kumakonda kuwonetsa mawonekedwe opotoka panthawi yokhumudwitsa. Pamene kuphipha kuchotsedwa, m'pofunika kuchotsa kuphipha kolemera. Panthawi yosokoneza, kupsinjika kwamkati kumachitika, ndipo ductility ya tendon yokhumudwitsa imachepa, ndipo mawonekedwe a brittle fractures amapezeka mosavuta. Kukonza ulusi kumafuna ziwiri. Njira ziwirizi zatha.
